The present invention relates to augmented reality with persistent digital content linked to a physical location. More specifically, the present invention links location coordinates descriptive of a physical location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with location specific digital content. According to the present invention, digital content remains persistent with a location even if visual aspects of the location change.
The use of smart devices has become a daily part of life for many people. A smart device may be used as a communication tool and to receive information. Communication is generally on a point-to-point basis, and sometimes on a point to multiple points basis. Information dissemination to unknown recipients, or to recipients that are not ascertainable at a time of generation of the information, requires posting or storing of the information in a centralized server where the information may be retrieved using traditional queries and search engines, such as Google or social media.
However, it is difficult, if not impossible to automatically receive information pertinent to a designated area. And it is especially difficult to receive information related to a subject area when a user does not know what to ask for, or what type of information may be available to the user.
Accordingly, the present invention combines methods and apparatus for providing digital content included in an Agent interface based upon an area at least partially defined by a geospatial position contemplated by the Agent interface. In some embodiments, an area defined by a geospatial position contemplated by an Agent is based upon a current position occupied by the Agent and a direction of interest provided by the Agent.
Digital content linked to a physical area is provided to an Agent based upon an identification of the Agent, where the Agent is, and which direction the Agent is oriented towards. In some embodiments, the present invention provides an interactive user interface with content derived from an immediate environment the Agent is located in and virtual content. For example, the present invention enables a user to direct a Smart Device, such as a smart phone, towards an area of interest to the user and a user interface is presented on the user's smart device (and/or a remote smart device) the interface includes an augmented reality environment that combines a rendition of the physical environment present to the user and location specific information in the form of digital content.
For example, a transceiver may be co-located with a sensor and engage in wireless communication. Based upon the wireless communication, location coordinates indicating where the sensor is located. The sensor quantifies a condition at a specific location. When a user views the physical area containing the sensor with the Smart Device, the Smart Device displays a rendition of the area monitored by the sensor and with the conditions quantified by the sensor.
Essentially, the present invention enables point and query (or ask and query) access to information or other content close to a Smart Device. The Smart Device may be used to generate an interface indicating what people, equipment, vehicles, or other items are viewable to the Smart Device and place those items into the context of the environment surrounding the Smart Device.
In general, the present invention associates digital content with Tags associated with location coordinates. A Tag may include one or more of a Physical Tag, a Virtual Tag, and a Hybrid Tag (as described in the Glossary below). Tags provide persistent access to specified digital content based upon the Tag's association of the content with a set of location coordinates and/or an area of positional coordinates including the location coordinates. For example, a set of positional coordinates may be located near an architectural aspect of a structure, such as a point of intersection of two beams. A Tag may be associated with the set of positional coordinates. An Area of digital content interaction (e.g., retrieval of digital content and/or placement of digital content for subsequent retrieval) may include the set of positional coordinates and also include an area comprising additional sets of positional coordinates, surrounding the set of positional coordinates, adjacent to the set of positional coordinates, and/or proximate to the set of positional coordinates.
This functionality is accomplished by establishing a target area and determining which tags are present within the target area. Tags may be virtual; in which case the virtual tags are associated with positional coordinates and viewable whenever a target area is designated to encompass the coordinates the virtual tag.
Alternatively, the tags may be physical, such as a small disk adhered to an item of equipment, vehicle, or a person's employee badge. Tracking of a position and content associated a physical tag may be updated in real time or on a periodic basis. Physical tags may be moved into a target area or the target area may be moved to encompass the physical tag. The present invention will automatically generate an interface indicating which tags contained in the interface, what those tags are associated with and where a tag is in relation to the Smart Device. It will also access any information that has been stored and associated with the tag and present int on the Smart Device.
By aligning real world and virtual world content, a real world site experience is enriched with content from a geospatially linked virtual world. The virtual world content is made available to an Agent based upon a position and a direction of a Radio Target Area (“RTA”) specified by a Smart Device supported by the Agent. A geospatial position and direction of interest that is contained within the RTA is generated using wireless communication with reference point transmitters. Wireless communication capabilities of the Reference Point Transmitters determine parameters associated with a Wireless Communication Area (“WCA”). The RTA is a subset of the WCA.
The present invention provides for methods and apparatus for executing methods that augment a physical area, such as an area designate as a wireless communication area. The method may include the steps of transceiving a wireless communication between a Smart Device and multiple reference point transceivers fixedly located at a position within a wireless communication area; generating positional coordinates for the Smart Device based upon the wireless communication between the Smart Device and the multiple reference transceivers; establishing a radio target area for an energy receiving sensor; receiving energy into the energy receiving sensor from the radio target area; generating a digital representation of the energy received into the energy receiving sensor at an instance in time; generating positional coordinates for a tag at the instance in time, the tag comprising digital content and access rights to the digital content; determining the tag is located within the radio target area based upon the positional coordinates for the tag; generating a user interactive interface comprising static portions based upon the digital representation of the energy received into the energy receiving sensor; generating a dynamic portion of the user interactive interface based upon the positional coordinates for the tag and the positional coordinates for the Smart Device; receiving a user input into the dynamic portion of the user interactive interface; and based upon the user input received into the dynamic portion of the user interactive interface, including the digital content in the user interactive interface.
In some embodiments, multiple disparate energy levels may be received into the energy receiving sensor at the instance in time, each disparate energy level received from a different geospatial location; associating positional coordinates with the disparate energy levels; and indicating the disparate energy levels and relative positions of the disparate energy levels in the user interactive interface. A tag may include a virtual tag with the digital content and a location identified via positional coordinates.
In another aspect, a physical tag may include a transceiver capable of wireless communication with the multiple reference transceivers and the method may include transceiving a wireless communication between a tag and multiple reference point transceivers; and generating positional coordinates for the tag based upon the wireless communication between the tag and the multiple reference transceivers. The wireless communication between the Smart Device and the multiple reference point transceivers may be accomplished by transceiving using an Ultra-Wideband modality; Bluetooth modality or another wireless modality, such as WiFi.
A wireless communication area may be identified as including a radio transmission area of the energy receiving sensor and the wireless communication area may be based upon a communication distance of the Ultra-Wideband modality in an area encompassing the energy receiving sensor.
Transceiving a wireless communication between a tag and multiple reference point transceivers may be accomplished using w wireless modality such as, for example, a UWB or Bluetooth modality; and generating positional coordinates for the tag based upon the wireless communication between the tag and the multiple reference transceivers may be accomplished using the same modalities. Positional coordinates may include one or more of: Cartesian Coordinates, an angle of arrival and an angle of departure and a distance.
In another aspect, access rights to tag content may be required and based upon an identifier of the Smart Device or a user operating the Smart Device. A dynamic portion of the user interactive interface may include an icon indicative of the digital content associated with the tag.
In some embodiments, the present invention combines methods and apparatus for providing multifactor security protection of digital content. Factors in addition to the typical two factor security are based upon location coordinates of Tags (Virtual, Physical or Hybrid) that are associated with specified digital content. For example, a third factor may be based upon knowledge of a location of a Virtual Tag and/or Physical Tag storing the digital content; and a fourth factor may be based upon a physical location of a user or other Agent requesting access to the digital content. A potential fifth factor may include location coordinates of the user's smart device for a time period prior to the request for access to the protected digital content. According to the present invention, knowledge of the location of the Tag may be provided via an Augmented Reality interface with icons specific to a User being presented in the context of an image of a physical environment. Determination of a physical location of the user may be accomplished via wireless communications.
Factors in security authentication according to the present invention may be based upon one or both of: location coordinates for a user's smart device at the time of request for access to the Virtual Tag; and location coordinates of the user's smart device at time intervals prior to the request for access to the Virtual Tag. In some embodiments, an Augmented Reality interface manifests interactive icons that may be selected to provide access to the digital content “in” or otherwise associated with the Virtual Tag. An AR view includes interactive icons incorporated into image data representative of a physical area, such as an image based upon energy levels received into a charged couple device (CCD). Image data may be live “video” type image data or a still image.
In some embodiments, access to protected digital content requires the presence of an Agent in a defined geospatial area and corresponding location coordinates. The A/R interface incorporates interactive icons representative of the Virtual Tags at the locations specified by the location coordinates within the defined geospatial area. For example, an authorized geospatial area may include a physical structure; such as an office; a manufacturing facility; a warehouse or other storage facility; a military base; an airport; a construction worksite; an energy substation; a cellular tower site; a distribution center; a residential facility; an infrastructure, such as a bridge or tunnel; or other definable area.
Digital content linked to a physical area is provided to an Agent based upon an identification of the Agent, where the Agent is, and which direction the Agent is oriented towards. In some embodiments, the present invention provides an interactive user interface with content derived from an immediate environment the Agent is located in and virtual content. For example, the present invention enables a user to direct a Smart Device, such as a smart phone, towards an area of interest to the user and a user interface is presented on the user's smart device (and/or a remote smart device) the interface includes an augmented reality environment that combines a rendition of the physical environment present to the user and location specific information in the form of digital content.
A Virtual Tag infrastructure (VTI) provides a cryptographic technique that enables secure access to digital content via one or both of: secure networks; and an insecure public networks, such as the Internet. Virtual Tag cryptography reliably verifies an authorized request for access to digital content by a user or other Agent. In various embodiments, location coordinates are used to verify an authorized request to access protected digital content. The location coordinates correspond with one or more of: a location of a Virtual Tag; a location of a Physical Tag; a location of a smart device; and a location of another type Node.
In another aspect, Virtual Tag cryptography may be based upon location coordinates of designated areas of access to the digital content. Still further aspects may rely upon location coordinates of a Virtual Tag, a Physical Tag a smart device and/or a Node at intervals over a defined period of time prior to a request to access the digital content.
The VTI includes a system for the creation, storage, and distribution of digital content based upon presentation of authorizing credentials based, at least in part, upon location coordinates. The location coordinates may relate to a first security factor based upon one or both of a location of a Virtual Tag; and a Physical Tag; and a second factor based upon a location or sequence of locations of an Agent seeking to access the digital content to retrieve, modify, or deposit digital content.
In some embodiments, authorizing credentials may include an improved version of a PKI infrastructure, wherein the PKI public certificate is a value based upon location coordinates of at least one of a: Virtual Tag, Physical Tag, Smart Device, or other Node. The public certificate may be used to verify that a particular Virtual Tag is accessible to an entity requesting access. The VTI creates digital certificates that map Virtual Tags to locations, and maps authorized access areas to users requesting access (or who may request access). In this manner, the public key includes positional coordinates, or may be derived from positional coordinates. For example, derivation may be accomplished via an algorithmic processing of location coordinate values. Location coordinate values may be those determined at a time interval during a request to access the digital content, and/or during a time interval prior to a request to access digital content.
A VTI may include one or more of: a VTI certificate authority that stores, issues and processes digital certificates based upon location coordinates and time interval values; a central directory providing a secure location in which location values associated with Virtual Tags digital content are stored and indexed; and a Virtual Tag management system managing positional coordinates and associated digital content.
The present invention a multifactor authentication for protecting access to digital content that includes a mathematical scheme for verifying the authenticity of a request for access to the digital content and authenticity of a provider of digital content. Essentially, a valid digital signature or login credentials based upon location coordinate values, personal knowledge and possession of a known hardware device provides the VTI with extremely strong evidence to determine that an access request was submitted by a known sender, resulting in a location/user based authentication, and confidence in the integrity of the digital content.
In some embodiments, the present invention enables point and query (or ask and query); and point and deposit; access to information or other digital content proximate to a Smart Device. The Smart Device may be used to generate an interface indicating what people, equipment, vehicles, or other items are viewable to the Smart Device and place those items into the context of the environment surrounding the Smart Device.
The details of one or more examples of the invention are set forth in the accompanying drawings and the description below. The accompanying drawings that are incorporated in and constitute a part of this specification illustrate several examples of the invention and, together with the description, serve to explain the principles of the invention: other features, objects, and advantages of the invention will be apparent from the description, drawings, and claims herein.
The accompanying drawings, that are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and, together with the description, serve to explain the principles of the invention:
The present invention relates to the provision of digital content placed in a real world context, such as a human user interface, including for example an augmented reality interface, or a machine interface, with persistent digital content linked to a physical location. In some embodiments, the present invention links a physical area with digital content and thereby enables an augmented reality user interface with aspects of the physical area combined with location designated digital content. According to the present invention, digital content remains persistent with a location even if visual aspects of the location change.
Some embodiments include methods and apparatus for determining virtual world digital content linked to positional coordinates; and displaying real-world energy levels integrated with and aligned with the virtual-world digital content.
In some examples, a carefully placed reference point Node may function as a transceiver of signals. For example, a Node may receive and transmit signals in a radio frequency band of the electromagnetic spectrum. In a simple form, a Node may broadcast a radio frequency wireless communication. Nodes may also be capable of receiving a radio frequency on a same radio frequency and/or a different radio frequency as a received radio frequency. Frequencies utilized for wireless communication may include those within the electromagnetic spectrum radio frequencies used in one or more of: UWB, Wi-Fi, and Bluetooth modalities, as well as IR, visible and UV light as examples of transmission modalities. In some embodiments, sound emanations may also be used as a communication mechanism between a Smart Device and a reference point Node and/or between two Nodes. In various aspects of wireless communication, the Nodes may function to communicate a timing value via their electromagnetic or sonic transmissions or data other than timing signals, such as a digital value representing a condition quantified with an electronic sensor. Accordingly, wireless communications may provide data identifying information unique to the Node, data related to the synchronization of timing at different well located reference points and may also function as general data communication Nodes.
A triangulation calculation and/or a distance and angle indicating a position of a Smart Device or a Node may result from a system of multiple reference position Nodes communicating timing signals to or from the Smart Device or Node. Methods of calculating positions via wireless communications may include one or more of: RTT, RSSI, AoD, AoA, timing signal differential and the like. Triangulation or other mathematical techniques may also be employed in determining a location.
A process is disclosed for determination of a position based upon wireless communication between a Node and/or Smart Device and with reference point transceivers. The process may be accomplished, for example via executable software interacting with the controller, such as, for example via running an app on the Smart Device or as a service on a server accessible via the Internet.
In the following sections, detailed descriptions of examples and methods of the invention will be given. The description of both preferred and alternative examples though thorough are exemplary only, and it is understood that, to those skilled in the art, variations, modifications, and alterations may be apparent. It is therefore to be understood that the examples do not limit the broadness of the aspects of the underlying invention as defined by the claims.
In some embodiments, the location of a Node. may be determined via discernment of a physical artifact, such as, for example a visually discernable feature, shape, or printed aspect. A pattern on a surface may convey a reference point by a suitable shape such as a cross, Vernier or box structure as non-limiting examples. The printing may also include identification information, bar codes or lists of location coordinates directly. A Smart Device ascertaining a physical reference mark and a distance of the Smart Device to the mark may determine a relative location in space to a coordinate system of the marks. Reference points may be coded via identifiers, such as a UUID (Universally Unique Identifier), or other identification vehicle. Marks tied to a geospatial coordinate system may be utilized to determine a relative location. A number of methods may be executed to determine a distance from the Smart Device to a mark such as, for example, a sensed reflection of light beams (preferably laser beams), electromagnetic beams of wavelength outside of the visible band such as IR, UV, radio and the like, or sound-based emanations. It may be important that the means of determining the distance can be focused into a relatively small size. It may be important that the means of determining the distance is reflected by the physical mark. For example, a light-source apparatus used to determine a distance may benefit from a mirror surface upon the physical mark. In addition, a reflected signal may emerge significantly towards a user. It may be desirable that physical reference points are placed with high accuracy at specific reference locations, or it may be desirable to be able to measure with high accuracy specific reference locations after placement.

A designated direction 112 may be generated based upon wireless communications and may be used to determine a targeted item 113 and/or a targeted direction. A designated direction may be determined via the wireless modalities discussed herein. Some embodiments will include one or more of: radio communications involving multiple antennas; radio communications with one or more antennas at two or more locations at different instances of time; a magnetometer; a compass; LiDAR; laser; sonic; accelerometer; gyroscope or other electronic mechanism.
A Radio Target Area 117 (sometime abbreviated as “RTA”) may be identified with an area of from which energy is received from a direction congruent with and/or overlapping an area indicated with the designated direction 112. In some embodiments, an RTA may also be congruent and/or overlap a field of view (FOV) of a camera device included in the Smart Device at the location of transceiver 105.
In another aspect, in some embodiments, one or more of a physical transceiver, such as one or more of: an IoT Tag 114; a Virtual Tag 115; and a Hybrid Tag 116. In general, an IoT Tag 114 includes a physical tag with a transceiver that transceives logical data that may include a timing signal from which a position may be calculated. In some embodiments, an IoT Tag 114 may also include an electronic sensor that generates digital content that may also be transceived and/or stored in the IoT Tag 114. A Virtual Tag includes digital content associated with a set of coordinates but does not include a physical transceiver. A Hybrid Tag 116 includes digital content associated with a set of coordinates similar to a Virtual Tag 115 and may be a subset type of Virtual Tag 115 that includes digital content generated via an IoT Tag 114, while the IoT Tag 114 was located at the coordinates associated with the Hybrid Tag 116.
In some embodiments, one or more of the IoT Tag (Virtual Tag 115), the Smart Device at the location of transceiver 105, and the Reference Point Transceivers 101-104 may comprise a Node with a transceiver, a controller, and a memory that may store digital content.
Still further, in some embodiments, a Node deployed as one or more of the IoT Tag (Virtual Tag 115), the Smart Device at the location of transceiver 105, and the Reference Point Transceivers 101-104 may receive a digital content download via a wireless modality other than the nodality used to determine a geospatial location 107 of the Smart Device at the location of transceiver 105, such as, for example via a cellular transmission or a satellite download in a remote area, such as a remote construction work site, a wilderness location, a hiking trail, a remote section of an aqueduct or utility or a pipeline (e.g. a gas or oil pipeline). Digital content downloaded and/or stored in a Node deployed as one or more of the IoT Tag (Virtual Tag 115), the Smart Device at the location of transceiver 105, and the Reference Point Transceivers 101-104 may be communicated during a transceiving process engaged in between Nods and/or device described herein.
Reference Point Transceivers 101-104 may be fixed in a certain location within or proximate to the Structure 106 and define a wireless communication area 111. The Reference Point Transceivers 101-104 may transceive in a manner suitable for determination of a position of one or more Transceivers 105 supported by an Agent 100. Transceiving may be conducted via one or more wireless transmission modalities between the Transceiver 105 supported by the Agent 100 and one or more Reference Point Transceivers 101-104.
By way of non-limiting example, Transceivers 105 supported by the Agent 100 may be included in, and/or be in logical communication with, a Smart Device, such as, one or more of: a smart phone, tablet, headgear, ring, watch, wand, pointer, badge, Tag, Node; a Smart Receptacle; headgear; or Tag supported by the Agent 100 or other Agent supportable device with Transceiver 105 operable to transceive with the Reference Point Transceivers 101-104.
The Reference Point Transceivers 101-104 may include devices, such as, for example, a radio transmitter, radio receiver, a light generator, a light receiver, a pattern recognizing device, a sonic or ultrasonic device. A radio frequency transceiver may transmitters and receivers operative to communicate via wireless modalities such as, for example: Wi-Fi, Bluetooth, Ultra-wideband (“UWB”), ultrasonic, infrared, or other communication modality capable of logical communication between Transceivers 101-105.
In some embodiments, a Reference Point Transceivers 101-104 may include a multi-modality transceiver, which communicates more locally via a first communication modality and a second communication modality. Each of the first modality and the second modality, may include for example apparatus and software code for wireless communications via one of: UWB, Bluetooth, Wi-Fi, ANT, Zigbee, BLE, Z Wave, 6LoWPAN, Thread, Wi-Fi, Wi-Fi-ah, NFC (near field communications), Dash 7, Wireless HART, or similar modality. In some embodiments, a first communication modality may engage in wireless communications with a first set of distance constraints and a second communication modality may engage in wireless communication with a second set of distance constraints. For example, a first communication modality may involve UWB communications modalities that travel a shorter distance than a second communication modality but may provide a more accurate location determination. In this example, a second communication modality may include one or more of: satellite communications (e.g., GPS); cellular communication modalities (e.g., 3G, 4G 5G and the like), sub GHz communications, or another modality.
In some embodiments, satellite communications (e.g., global positioning system “GPS”) and/or cellular communications may be used to determine an identification of a structure 106 within which transceiving with the Reference Point Transceivers 101-104 may be established.
Wireless communications between Transceivers 101-105 may engage in logical communications to provide data capable of generating one or more of: Cartesian coordinates, polar coordinates, vector values, AoA, AoD, RTT, RSS, a GPS position, or other data that may be utilized for one or more of: locating one or both of an Agent 100; indicating a direction of interest; and identify a Structure or defined area of structure 106. Logical communications may include digital data indicative or a value, which may be used, for example, to determine a distance via processes involving one or more of: a time difference of arrival (TDOA); frequency difference in arrival (FDOA); and time of flight (TOF).
A precise geospatial location 107 may be determined via triangulation based upon a measured distance from three or more Reference Point Transceivers 101-104. For example, a radio transmission or light signal may be measured and compared from the three reference point transceivers 101-103. Other embodiments may include a device recognizable via image analysis and a sensor or other Image Capture Device, such as a CCD device, may capture an image of three or more Reference Point Transceivers 101-104. Image analysis may recognize the identification of each of three or more of the Reference Point Transceivers 101-104 and a size ratio of the respective image captured with Reference Point Transceivers 101-104 may be utilized to calculate a precise position. Similarly, a height designation may be made via triangulation using the reference point transceivers as reference to a known height or a reference height.
Reference Point Transceivers 101-105 may include circuitry and logic capable of transceiving in a single modality, or multiple disparate modalities. Similarly, a Reference Point Transceivers 101-104 and/or an Agent-supported device at the location of Transceiver 105 may include multiple transceiver device, including, transmitters and receivers.
A modality, as used in conjunction with a Transceiver, transmitter and/or receiver refers to one or both of a bandwidth of wireless communication and a protocol associated with a bandwidth. By way of non-limiting example, a modality, as used in relation to a Transceiver, transmitter and/or receiver may include Wi-Fi; Wi-Fi RTT; Bluetooth; UWB; Ultrasonic, sonic, infrared; ANT, Zigbee, BLE, Z Wave, 6LoWPAN, Thread, Wi-Fi, Wi-Fi 33-ah, NFC (near field communications), sub-GHz, Dash 7, Wireless HART, or other logical communication medium.
Triangulation essentially includes determining an intersection of three distances 108-110, each of the three distances 108-110 calculated from a reference point transceivers 101-104 to an Agent-supported device at the location of transceiver 105. The presence invention allows for a first distance 108, to be determined based upon a wireless communication in a first modality; and a second distance 109 and a third distance 110 determined based upon a wireless communication in a same or different modality as the first modality. For example, a first distance 108 may be determined based upon a wireless communication using UWB; a second distance 109 may be determined based upon a wireless communication using Bluetooth; and a third communication may be determined based upon a wireless communication using ultrasonic communication (other combinations of same and/or different communication modalities are also within the scope of the present invention and may include, for example, infrared communications, image recognition, RFID, accelerometer readings or other data generated by an electronic device or mechanical mechanism).
A geospatial location 107 may be determined via triangulation based upon a measured distance from three or more reference point transceivers 101-103 to the transceiver 105 supported by the Agent 100. For example, timing associated with a radio transmission or light signal may be measured and compared from the three reference point transceivers 101-103. Other embodiments may include a device recognizable via image analysis and a sensor or other Image Capture Device, such as a CCD device, may capture an image of three or more reference point transceivers 101-104.
Additional embodiments may include image analysis of image data captured via a CCD included in a Smart Device to recognize the identification of each of three or more of the reference point transceivers 101-104 and a size ratio of the respective image captured where reference point transceivers 101-104 may be utilized to calculate a precise position. Similarly, a height designation may be made via triangulation using the reference point transceivers as reference to a known height or a reference height. In a similar fashion, triangulation may be utilized to determine a relative elevation of the Smart Device as compared to a reference elevation of the reference points.
In some embodiments, the geospatial location 107 of the Agent-supported device at the location of Transceiver 105 may be ascertained via one or more of: triangulation; trilateration; and multilateration (MLT) techniques.
In some embodiments, a geospatial location based upon triangulation may be generated based upon a controller receiving a measurement of angles between the position and known points at either end of a fixed baseline. By way of non-limiting example, a point of a geospatial location may be determined based upon generation of a triangle with one known side and two known angles. Moreover, a geospatial location based upon multilateration may be generated based on a controller receiving measurement of a difference in distance to two reference positions, each reference position being associated with a known location. Wireless signals may be available at one or more of: periodically, within determined timespans and continually. The determination of the difference in distance between two reference positions provides multiple potential locations at the determined distance. A controller may be used to generate a plot of potential locations. In some embodiments, the potential determinations generally form a curve. Specific embodiments will generate a hyperbolic curve.
The controller may be programmed to execute code to locate a relatively exact position along a generated curve, which is used to generate a geospatial location. The multilateration system thereby receives as input multiple measurements of distance to reference points, wherein a second measurement taken to a second set of stations (which may include one station of a first set of stations) is used to generate a second curve. A point of intersection of the first curve and the second curve may be used to indicate a specific location.
In another aspect, in some embodiments, the location of a Transceiver 101-105 may be determined and/or aided via discernment of data based upon a physical artifact, such as, for example a visually discernable feature, shape or printed aspect located within the Structure 106. Discernment of the physical artifact may, for example, be based upon topographical renditions of physical aspects included in the Structure, such as those measured using LIDAR, a magnetic force, image data (or a point cloud derived from image data). A pattern on a surface may convey a reference point by a recognizable pattern (which may be unique to the setting), Vernier or three-dimensional structure as non-limiting examples. A Smart Device ascertaining a physical reference mark and a distance of the Smart Device to the mark may determine a relative location in space to a coordinate system of the marks.
Marks and/or markers with a known location indicated via coordinate values tied to a geospatial coordinate system may be utilized to determine a relative location. Recognition of the marker may be accomplished for example, via one or more of image recognition, laser reflection, RFID activation and reading, sonic reading, LiDAR, or other recognition technology. Similarly, number of methods and apparatus may be executed in various embodiments, to determine a distance from the Smart Device to a mark such as, for example, a sense reflection of light beams (preferably laser beams), electromagnetic beams of wavelength outside of the visible band such as IR, UV, Radio and the like, or sound-based emanations.
In some examples, a carefully placed reference point Node may function as a transceiver of signals. For example, a Node may receive and transmit signals in a radio frequency band of the electromagnetic spectrum. In a simple form, a Node may detect an incoming signal and coincidently broadcast a radio frequency wireless communication. Frequencies utilized for wireless communication may include those within the electromagnetic spectrum radio frequencies used in UWB, Wi-Fi, and Bluetooth modalities, as well as IR, Visible and UV light as examples.
In some embodiments, sound emanations may also be used as a communication mechanism between a smart device and a Reference Point Transceivers 101-104. In some examples, the Reference Point Transceivers 101-104 may function to communicate data with their electromagnetic or sonic transmissions. Such communications may provide identifying information unique to the Node, data related to the synchronization of timing at different well located reference points and may also function as general data communication nodes. A triangulation calculation of the position of a Smart Device or a Node may result from a system of multiple reference position Nodes communicating timing signals to or from the Smart Device or Node. Methods of calculating positions via wireless communications may include one or more of: RTT, RSSI, AoD, AoA, timing signal differential and the like, Triangulation or other mathematical techniques may also be employed in determining a location.
The process of determination of a position based upon triangulation with the reference points may be accomplished, for example via executable software interacting with the controller in a Smart Device, such as, for example via running an app on the Smart Device.
Reference points may be coded via identifiers, such as a UUID (Universally Unique Identifier), or other identification vehicle.
Reference point transceivers 101-104 may be deployed in a defined area of structure 106 to determine a geospatial location 107 of an Agent 100 within or proximate to the defined wireless communication area 111. Reference point transceivers 101-104 may be fixed in a certain location and transceive in a manner suitable for a triangulation determination of the position of the Agent. Transceiving may occur via wireless transmission to one or more Transceivers 105 supported by the Agent 100. By way of non-limiting example, Transceivers 105 supported by the Agent 100 may be included in, or be in logical communication with, a Smart Device with Transceivers 105 able to transceive with the reference point transceivers 101-104.
The reference point transceivers 101-104 may include devices such as a radio transmitter, radio receiver, a light generator, or an image-recognizable device (i.e., an apparatus set out in a distinctive pattern recognizable by a sensor). A radio transmitter may include a UWB Node, Wi-Fi, Bluetooth, or other communication device for entering into logical communication between Transceivers 101-105. In some embodiments, Reference Point Transceivers 101-104 may include a Wi-Fi router that additionally provides access to a distributed network, such as the Internet. Cartesian coordinates (including Cartesian coordinates generated relative to a GPS or other reference point), or any other coordinate system, may be used as data that may be utilized for one or more of: locating one or both of an Agent 100; indicating a direction of interest; and identifying a Structure 106 or defined area of structure 106. A radio transmitter may include a router or other Wi-Fi device. The radio transmitter may include transmissions via an Ultra-Wideband (“UWB”) frequencies including, for example, 3.5-6.5 GHz; on Wi-Fi frequencies (300 MHz-60 GHz), sub GHz frequencies or another modality. A light generator may distribute light at human-safe intensities and at virtually any frequency known in the art. Such frequencies include, without limitation, infrared, ultraviolet, visible, or nonvisible light. Further, the light beacon may comprise a laser, which may transmit light at any of the aforementioned frequencies in a coherent beam.
This plurality of modalities allows for increased accuracy because each modality may have a different degree of reliability. For example, a Smart Device 101 and/or Smart Receptacle may measure a timing signal transmitted by a Reference Point Transceivers 101-104 within a different error tolerance than it may measure the receipt into a photodetector of infrared laser light. This has at least two principal benefits. First, a location calculation may, in some embodiments, be a weighted average of the location calculated from each modality. Second, outliers may be shed. For example, if the standard location calculation comprises a weighted average of the location as calculated by five modalities, but one modality yields a location greater than two standard deviations from the average computed location, then that modality may not be considered for future weighted location calculations.
Additionally, the radio transmitters and/or transceiver in the Smart Device may comprise multiple antennas that transmit signals in a staggered fashion to reduce noise. By way of non-limiting example, if there are three antennas, then they may transmit a signal in intervals of 20 milliseconds. Given this rate of transmission, a detected time of arrival may be used to determine the distance between the transmitter and the antenna (i.e., the Smart Device). Moreover, the antennas may comprise varying lengths to accommodate desirable wavelengths. Further, dead reckoning may be used to measure location, using traditional methods of numerical integration.
A precise location may be determined based upon wireless transmissions between Nodes, such as between a Smart Device and the Reference Position Transceivers. Timing determinations—as well as signal qualities like angle of arrival, angle of departure, transmission strength, transmission noise, and transmission interruptions—may be considered in generating relative positions of Nodes. Additional considerations may include AI and unstructured queries of transmissions between Nodes and triangulation logic based upon a measured distance from three or more Reference point transceivers 101-104. For example, a radio transmission or light emission may be measured, and timing associated with the radio transmission or light to determine a distance between Nodes. Distances from three reference point transceivers 101-103 may be used to generate a position of a Node in consideration. Other methodologies include determination of a distance from one or more Nodes and a respective angle of arrival and/or angle of departure of a radio or light transmission between the Node in consideration and another Node (Reference Point Node or dynamic position Node).
In some embodiments of the invention, position determination in a Structure or on a Property contemplates determination of a geospatial location using triangulation, trilateration, or multilateration techniques. In some embodiments, a geospatial location relative to one or more known reference points is generated. The geospatial location in space may be referred to as having an X, Y position indicating a planar designation (e.g., a position on a flat floor), and a Z position (e.g., a level within a Structure, such as a second floor) may be generated based upon indicators of distance from reference points. Indicators of distance may include a comparison of timing signals received from wireless references. A geospatial location may be generated relative to the reference points. In some embodiments, a geospatial location with reference to a larger geographic area is associated with the reference points, however, in many embodiments, a controller will generate a geospatial location relative to the reference point(s) and it is not relevant where the position is located in relation to a greater geospatial area. In addition to these Cartesian coordinates, polar coordinates may be used, as further described below.
A geospatial location based upon triangulation may be generated based upon a controller receiving a measurement of angles between the position and known points at either end of a fixed baseline. A point of a geospatial location may be determined based upon generation of a triangle with one known side and two known angles.
Triangulation essentially includes determining an intersection of three distances 108-110, each of the three distances 108-110 calculated from a reference point transceivers 101-104 to an Agent-supported device at the location of transceiver 105. The present invention allows for a first distance 108 to be determined based upon a wireless communication in a first modality; and a second distance 109 and a third distance 110 determined based upon a wireless communication in a same or different modality as the first modality. For example, a first distance 108 may be determined based upon a wireless communication using UWB; a second distance 109 may be determined based upon a wireless communication using Bluetooth; and a third communication may be determined based upon a wireless communication using ultrasonic communication (other combinations of same and/or different communication modalities are also within the scope of the present invention).
Geospatial location 107 may be based upon triangulation generated based upon a controller receiving a measurement of angles between the position and known points at either end of a fixed baseline. A point of a geospatial location may be determined based upon generation of a triangle with one known side and two known angles.
In some embodiments, a geospatial location 107 may be based upon multilateration and generated based on a controller receiving a measurement of a difference in distance to two reference positions, each reference position being associated with a known location. Wireless signals may be available at one or more of: periodically, within determined timespans, and continually. The determination of the difference in distance between two reference positions provides multiple potential locations at the determined distance. A controller (such as one in the Smart Device) may be used to generate a plot of potential locations. In some embodiments, the potential determinations generally form a curve. Specific embodiments will generate a hyperbolic curve.
A controller may be programmed to execute code to locate an exact position along a generated curve, which is used to generate a geospatial location. The multilateration thereby receives as input multiple measurements of distance to reference points, wherein a second measurement taken to a second set of stations (which may include one station of a first set of stations) is used to generate a second curve. A point of intersection of the first curve and the second curve is used to indicate a specific location.
In exemplary embodiments, as described herein, the distances may be triangulated based on measurements of UWB, Wi-Fi or sub GHz strength at two points. Transceiver signals propagate outward as a wave, ideally according to an inverse square law. Ultimately, a crucial feature of the present invention relies on measuring relative distances between two points. In light of the speed of Wi-Fi waves and the real-time computations involved in orienteering; these computations need to be as computationally simple as possible. Thus, depending upon a specific application and mechanism for quantifying a condition or location, such as a measurement, various coordinate systems may be desirable. In particular, if the Smart Device moves only in a planar direction while the elevation is constant, or only at an angle relative to the ground, the computation less complicated.
One exemplary coordinate system includes a polar coordinate system. One example of a three-dimensional polar coordinate system is a spherical coordinate system. A spherical coordinate system typically comprises three coordinates: a radial coordinate, a polar angle, and an azimuthal angle (r, θ, and φ, respectively, though θ and φ are occasionally swapped conventionally).
By way of non-limiting example, suppose Point 1 is considered the origin for a spherical coordinate system (i.e., the point (0, 0, 0)). For each Transceiver 101-105, emitter e1, e2, e3, . . . can be described as points (r1, θ1, φ1), (r2, θ2, φ2), and (r3, θ3, φ3) . . . respectively. Each of the r1's (1≤i≤3 or more) represent the distance between the Transceiver 101-105 emitter and the Transceiver 101-105 receiver on the Smart Device 101 or Smart Receptacle (see
It is understood that in some embodiments, an azimuth may include an angle, such as a horizontal angle determined in an arcuate manner from a reference plane or other base direction line, such as an angle formed between a reference point or reference direction; and line (ray or vector) such as a ray or vector generated from or continuing to a Smart Device. In preferred embodiments, the ray or vector may be generally directed from a Reference Position Transceiver towards, and/or intersect one or more of: an item of interest; a point of interest; an architectural aspect (such as a wall, beam, header, corner, arch, doorway, window, etc.); an installed component that may act as a reference in an augmented virtual model (AVM) (such as, for example, an electrical outlet, a light fixture, a plumbing fixture, an architectural aspect; an item of equipment; an appliance; a multimedia device, etc.); another Reference Position Transceiver or other identifiable destination.
Accordingly, in some embodiments, a spherical coordinate system may include Reference Position Transceiver that is capable of determining an angle of departure of a location signal and a Transceiver that is capable of determining an angle of arrival of the location signal; one or both of which may be used to facilitate determination of an applicable azimuth.
According to various embodiments of the present invention, one or both of an angle of departure and an angle of arrival may therefore be registered by a Transceiver that is transmitting and/or receiving wireless signals (e.g., radio frequency, UWB, Bluetooth 5.1, sonic frequency, or light frequency).
In some embodiments, locating an Agent occurs in or proximate to a Structure in which Reference point transceivers, (including, for example, one or more of: Wi-Fi Transceivers, UWB Transceivers, Bluetooth Transceivers, infrared Transceivers, and ultrasonic Transceivers) may be located above and/or below an Agent. In these embodiments, a cylindrical coordinate system may be more appropriate. A cylindrical coordinate system typically comprises three coordinates: a radial coordinate, an angular coordinate, and an elevation (r, θ, and z, respectively). A cylindrical coordinate system may be desirable where, for example, all Wi-Fi emitters have the same elevation. Angles may be determined as described above.
In some embodiments, transceivers 101-105 including arrays of antennas may be used to measure an angle of radio communication (e.g., angle of arrival and/or angle of departure). Various configurations of transmitting antennas and receiving antennas may be used. For example, a radio transmission may be transmitted with a single antenna and received with a receiver with an array of antennas, the phase or timing difference of arriving signals can be used to calculate the angle at which the signals emerged. In angle of departure schemes, a transmitter may contain an array of antennas and may send a pattern of signals through the array that arrive at a receiver with a single antenna where the angle of departure (AoD) is communicated.
Measurement of angle of arrival may be performed as mentioned by calculation of time difference of arrival at the antennas in an array or alternatively can be performed by rotation of antenna elements.
Some modalities, such as those modalities that adhere to the Bluetooth 5.1 or BLE5.1 standards, allow a Smart Device 101, Smart Receptacle, or other Node to determine an angle of arrival (AoA) or an angle of departure (AoD) for a wireless transmission. An array of antennas may be used to measure aspects of the Bluetooth signaling that may be useful to calculate these AoA and AoD parameters. By calibrating an antenna system, the system may be used to determine angles in one or two dimensions depending on the design of the antenna. The result may be significant improvement in pinpointing the location of origin of a signal.
An array of antennas may be positioned relative to each other and a transmitting transceiver to allow for extraction of an AoA/AoD. Such an array may include a rectangular array; a polar or circular array; a linear array; and a patterned array, where a number of antennas are deployed in a pattern conducive to a particular environment for transceiving. Antennas may be separated by characterized distances from each other, and in some examples, a training protocol for the antenna array results in antenna positioning incorporating superior angle and location precision. Some transceivers may transceive in 2.4-2.482 GHz frequency bands, and thus the radiofrequency transmissions may have wavelengths in the roughly 125 mm length scale. A collection of antennas separated by significantly less than the wavelength may function by comparing a phase of RF transmissions arriving at the antennas. An accurate extraction of phase differences can yield a difference in path length that, when accumulated, can lead to a solution for the angles involved. In some embodiments, Transceivers 101-105 may include antenna arrays combined with batteries and circuitry to form complete self-contained devices.
In an example, an Agent-supported device at the location of transceiver 105 may be located at a position and may transmit a signal of the various types as have been described. Nodes, such as Reference Point Transceivers 101-104 located at reference points in the wireless communication area around the position of the Agent 100 may receive the transmission and determine the angle of arrival of that transmission. Similarly, transmission associated with other reference point transceivers 101-103 may also determine an angle of arrival of transmissions. In some embodiments, reference point transceivers 101-103 may communicate with one or more of: each other, a smart device, a controller, or other processor to mathematically process multiple angles and locations of the transceivers and calculate a position of a transmission emanation. In examples where calculations are not performed at a smart device, a communication to the smart device of the calculated position may be communicated.
In certain embodiments of the invention, a direction of interest indicated by Smart Device 101 or a Smart Receptacle (see
In another aspect, captured data may be compared to a library of stored data using image recognition software to ascertain and/or affirm a specific location, elevation and direction of an image capture location and proper alignment with the virtual model. Similarly, a Smart Device may capture image data and/or audio data from a determined position and in some embodiments, a determined direction. The captured image data may be stored in a library of image data and referenced in subsequent analysis of where a location is.
In various embodiments, a position of an Agent Smart Device may be determined by any of the methods described herein. A user or other Agent may position a sensor of an associated smart device to be pointing in a direction of interest and obtain an image. The image may be passed on to a server with access to database of images containing stored images of the space around the user. Algorithms on the server may compare the stored images to the image captured by the user and may calculate adjustments to the comparative image based on where the reference image was taken in relationship to the location of the user. Based on the determination that the calculated adjusted image compared to the image obtained by the user in the direction of interest, a direction may be inferred with known location of objects in the reference image. In some variations, the differences in features of the user obtained image compared to a reference image may be used to calculate a direction of interest based upon a location at which the reference image was obtained.
In some examples, stored images may be obtained at multiple angles to improve accuracy of orienteering. These examples may include sensor arrays, audio capture arrays and sensor arrays with multiple data collection angles. In some examples a full 360-degree sensor perspective may be obtained by such arrays. In some directional arrays, a Sensor array (including image capture sensors) may include at least 120 degrees of data capture. By collecting such image collections as the Sensor/Sensor systems are moved, a database of image perspectives may be formed and utilized to assist in orienteering as described.
Non-limiting examples may include image-based identification where a device with some imaging means, including but not limited to a mobile device sensor, tablet device sensor, computer sensor, security sensor, or A/R headset sensor, may image points of interest in a direction of interest. These points of interest may be identified. Image recognition software may be used to identify the visualized landscape by its identifying features. Machine learning may be used to train systems using this software to identify specific features of the environment in question.
To create a supplemental topographic part of a model of the environment of a user, laser scanning and/or LiDAR may be performed during the acquisition of imagery for a reference database. A resulting three-dimensional shape model may be modelled with the captured imagery to help in the comparison to user data. Three-dimensional shapes can be used to infer comparative imagery at different angles of acquisition than exist in a database. In another example, a device of a user may have the means of performing laser scanning or LiDAR scanning of the environment as well as obtaining images. The resultant three-dimensional data or a composite of the three-dimensional data, and the imagery may be used to recognize features and determine a direction that the user was facing when they collected the image.
The results of scanning may be stored and presented in different manners. In some examples, the scanned data may be represented by a point cloud representation; in other examples an estimated topographic surface representation may be used to visualize the three-dimensional shape data obtained. In some examples, outward facing planes of the surface topography may have the captured imagery superimposed upon them. The resulting image and three-dimensional models may be used to calculate a direction of interest or a device field of view in a dynamic sense or alternatively upon user request.
In some examples other methods of capturing spatially accurate information may include the use of drones and optical scanning techniques which may include high resolution imagery obtained from multiple viewpoints. Scanning may be performed with light based methods such as a CCD sensor. Other methods may include infrared, ultraviolet, acoustic, and magnetic and electric field mapping techniques.
In other embodiments, a single distance to a point of interest in an image, which may be obtained by a laser, other collimated light source, sound source or the like, may be used with models of the environment of the user. A comparison of the imagery and the measurement of the distance of the user to a prominent feature in the image may allow for an orientation of the user to be determined algorithmically.
In some exemplary embodiments, radio frequencies used for wireless communication include sound waves used to perform one or more of: location determination; movement tracking in interior or exterior areas; and distance calculation. Sound wave transmissions include a number of significant attributes, which may translate into a benefit for a given set of circumstances when used for RF based location determination.
According to the present invention, sonic waves may be deployed independently, or in combination with electromagnetic transmissions and reception of logical communications utilizing other bandwidths, such as bandwidths associated with Ultrawideband, Wi-Fi, Bluetooth, Ultrawideband, ANT, infrared or almost any wavelength in the Industrial, Scientific, and Medical bands (sometimes referred to as “ISM Bands”).
For example, sound waves travel through an ambient atmosphere at a significantly slower speed than electromagnetic radiation (6×10{circumflex over ( )}2 m/sec versus 3×10{circumflex over ( )}8 m/sec). Therefore, a relative accuracy for measurements related to travel times may be improved in some environments by orders of magnitude using sonic-based location tracking as compared to electromagnetic-based measurements. Therefore, using sonic communications may result in increased accuracy of location determination, in some environments.
The present invention also provides for sonic wave emanations may be used to complement electromagnetic emanations based upon a tendency that sonic waves generally do not efficiently penetrate walls other physical items or structures. Sonic transceivers may be particularly advantageous in a defined area where location can be unambiguously determined to be within a particular room (the use of multiple bandwidth transmitting and receiving for different purposes is further discussed below). Sound wave interaction with a solid surface, such as a wall, may require that for optimal performance, transceiver/transmitters/receivers to be located in each room where location detection is desired. In some embodiments, a reflected sonic transmission may be received and analyzed to determine an effect of the reflected nature of the transmission.
Accordingly, methods may be employed using sonic emanations and reception for location determination. In general, frequencies of effective indoor sonic location detection may be at ultrasonic bandwidths (commonly used bandwidths include frequencies of between 1 MHz and 10 MHz, although frequencies of less than 50 kHz to greater than 200 MHz are possible). The utilized frequencies may be either below or above audible detection by people or other animals in the location, such as at frequencies above 20 kHz.
Sound waves may be used to perform one or more of: location determination, movement tracking in interior or exterior locations, and distance calculation from a position to a Smart Device at the location of transceiver 105, which may be accomplished based upon transmission and receipt of sonic transmission. Sound wave transmissions include several significant attributes, which may be beneficial for a given set of circumstances when used for radiofrequency-based location determination. According to the present invention, sonic waves may be deployed independently, or in combination with, transmissions and reception of logical communications utilizing other bandwidths, such as bandwidths associated with Wi-Fi, Bluetooth, ANT, infrared or almost any wavelength in the ISM Bands.
In some examples, as may be used in orienteering herein, an Agent-supported device at the location of transceiver 105 may support receivers, transmitters or transceivers that interact with ultrasonic transceivers fixedly secured to a reference point position, such as via mechanical mounting within a room environment. An ultrasonic positioning system may have indoor positioning accuracy at centimeter, millimeter, and even sub-millimeter accuracy. Multiple ultrasonic Transceivers may transceive from an Agent-supported device to communicate with fixed reference point transceivers may transmit signals. Arrival of the sound transmissions may be accurately timed and converted to distances. In some embodiments, distance determinations may be improved with knowledge of temperatures in the environment containing the sound transceiving. For example, temperature may be measured at one or more of: an Agent-supported Smart Device, a Reference Point position, and an ambient environment.
In some examples, synced timing apparatus is able to generate a location of a stationary Agent to within centimeter accuracy using sonic wave transmissions and reception and preferably within several millimeters of accuracy. In addition, in some embodiments sensors are able to detect frequency shifts within the sonic emanations which may add information about the relative rate of movement of the Agent, which may then in turn allow for correction to the timing signals.
In some examples, a combination of radio frequency emissions and ultrasonic emissions may be used. For example, a complement of radio frequency emissions/receptions and ultrasonic of radio frequency emissions and ultrasonic emissions may be reconciled to generate more accurate location determination. In another aspect, a radio frequency signal may be used to transmit syncing signals that establish a time that ultrasonic signals are transmitted. Since, the electromagnetic transmissions may be orders of magnitude faster than sound transmissions, the electromagnetic transmissions relatively small time of travel from the Transceivers to the Agent may be negligible and therefore used as “zero-time” setpoints as received at the Agent-supported Transceiver. In such embodiments, a controller determining a location may use not only relative arrival times, but also a delta time between a radiofrequency transmission and ultrasonic transmission to determine a distance from a transmitting Transceiver. An array of such ultrasonic and/or radiofrequency transceivers provide increased accuracy in triangulating a location of the Agent.
In still further examples, RF communications may transmit a syncing pulse and also transmit digital data about various aspects of a defined area, such as the defined area's identification, its relative and/or absolute location in space and other refinements. In some examples, data related to improved distance calculation may also be transmitted by RF communication such as temperature of the environment, humidity and the like which may influence the speed of sound in the environment as a non-limiting example. In some examples, such a system may result in millimeter level accuracy of position determination.
In some examples, the process may be iterated to refine the direction of each of the ultrasonic transmitters and maximize signal levels of the transmission which may provide additional information in the calculation of a position. UWB, Bluetooth, Wi-Fi, ANT, Zigbee, BLE, Z Wave, 6LoWPAN, Thread, Wi-Fi, Wi-Fi-ah, NFC (near field communications), Dash 7, and/or Wireless HART transmissions may be used for data communications and syncing. In other examples, an Agent-supported device at the location of transceiver 105 may be moved and an iterative process may be used to track the Agent-supported device at the location of transceiver 105 as it moves through space. Stationary Agents may be tracked with submillimeter accuracy in some embodiments.
A direction dimension may be based upon multiple transceivers included in a Smart Device or a Smart Receptacle or via a movement of a Smart Device or Smart Receptacle while an Agent supporting the Smart Device or Smart Receptacle remains in a stationary position in relation to reference, such as a ground plane position. For example, a device with a controller and an accelerometer, such as mobile Smart Device, may include a user display that allows a direction to be indicated by movement of the device from a determined location acting as a base position towards a feature in the intended direction where the movement results in an extended position. In some implementations, the Smart Device may first determine a first position based upon triangulation with the reference points and a second position (extended position) also based upon triangulation with the reference points.
As described above, facing a mobile device towards an area in a Structure and movement of the mobile device in a particular pattern may be used to ascertain a specific area in space to be interpreted by various methods. In some examples, the leading edge of a smart device, or the top portion of the user screen (in either portrait or landscape mode of display) may be the reference for the direction pointed in by the user. If the smart device is held at an angle relative to the ground, in some examples, the angle formed by the perpendicular to the top portion of the user screen may be projected upon the ground and that projection taken as the indication of direction.

An Authorized Transaction Area (ATA) 209 may be specified to indicate an area from which a Smart device 205 is authorized to perform transactions with the Transaction Apparatus 208, In some embodiments, an ATA 209 may be exclusive to a particular Transaction Apparatus 208. For example, as discussed further below, an ATA 209 may be exclusive to transactions with a specified Transaction Apparatus 208, such as, for example, a particular workstation; dispensing apparatus; building delivery; utility station; point of sale device; and construction site under management.
Inclusion of a Smart device 205 within an ATA 209 may be determined according to any of the methods and apparatus discussed herein, in addition a Transaction Apparatus Transceiver (TAT) 210 may be positioned with the Transaction Apparatus 208 (such as, co-located with, or incorporated into the Transaction Apparatus 208). The TAT 210 may include a relatively shorter range and more accurate location modality than GPS, such as one or more of: UWB, Bluetooth, Wi-Fi, ANT, Zigbee, BLE, Z Wave, 6LoWPAN, Thread, Wi-Fi, Wi-Fi-ah, NFC (near field communications), Dash 7, and/or Wireless HART transmissions. The TAT 210 may provide data sufficient to calculate an ATA/Smart Device distance 206 indicative of how far the Smart Device at the location of transceiver 105 is from the TAT 210 based upon a timing signal included in transceiving between the TAT 210 and the Smart Device at the location of transceiver 105.
In general, an ATA/Smart Device distance 206 may not be enough to determine that the Smart Device at the location of transceiver 105 is located within a transaction Apparatus 208 since a radio distance is often a radius. Therefore, the present invention provides for a TAT 210 to provide for directional transmissions. For example, a directional transmission may be limited to transmission from a front side of the transaction Apparatus 208 in a forward direction (as indicated by the arrow).
In addition, one or more Reference Point Transceivers 104-104 may engage wireless communications with the Smart Device 205 and a respective distance 201-204 between the respective reference point transceivers 101-104 and the Smart Device 205 may be calculated. Since only one respective distance 201-202 per reference point transceivers 101-104 will intersect a radius of a distance from a TAT 210, a determination made be made as to whether a SD is within an ATA 209.
With a Smart Device 205 positioned within an ATA 209, a transaction with improved security may be entered into and completed. A number of factors may be ascertained before a transaction with the transaction Apparatus 208 is executed. In some preferred embodiments, the completion of the transaction with the transaction Apparatus 208 will include one or more of: a) designating a user via a unique user identification; b) exchange of a user password, private key, synchronous dynamic password or other security code; c) location verification via wireless communication, which may include determination that the Smart Device at the location of transceiver 105 is within a ATA 209; identifying a transaction Apparatus 208; d) present transaction Apparatus 208 credentials to a transaction process; f) present credentials to a transaction process; g) designate actions to be completed during transaction execution; h) execute the actions; generation of an augmented reality icon viewable form the ATA 209; and interaction with the A/R icon.
According to the present invention, presentation of credentials from one or both of the transaction apparatus 208 and Agent 100 may only be made once location determinations indicate that the Agent 100 with the User Smart Device at the location of transceiver 105 is within the ATA 209.
In addition, in some embodiments, credentials may be withheld until an A/R Virtual Tag icon has been generated and made available to the unique identifier of the user. The Virtual Tag icon will be located in virtual space at a geospatial position that is viewable via an A/R interface generated with input from geospatial indicators generated by the Smart Device. The viewable area may include a Radio Target Area for an energy receiving device in (or attached to) the Smart device. Geospatial indicators may include, for example, location coordinates for the Smart Device that are generated as discussed herein. Generation of the icon in a virtual space that is aligned with a specific location creates a deterrent to unauthorized access to the Transaction Apparatus since a person that is not present to the TA will not be able to view the Virtual Tag icon and therefore not be able to interact with the icon in order to complete a process for gaining access to the secure transaction.

In some embodiments, a presence of the Smart Device at the location of transceiver 105 within an ATA 209A permits an Agent 100 to enter User credentials. In other embodiments, the locating of the Smart Device at the location of transceiver 105 within the ATA 209A causes a first controller (such as a CPU in a workstation 212) to execute a security related process that presents User credentials associated with the Smart Device at the location of transceiver 105 to a related login process. Presentation of credentials may also be a part of other various secure transactions that require different credentials to be presented. In addition, credentials from one or both of a TA, such as the workstation 212, and an Agent 100 may be presented to a process that will transacted.
In some embodiments, a Virtual Tag 211A is presented at location coordinates within an RTA (not illustrated). The Virtual Tag 211A is preferably viewable from within the ATA 209A with the Smart Device at the location of transceiver 105, when the Smart Device at the location of transceiver 105 is supported by the Agent 100.

According to the present invention, a personnel, which in some embodiments may also be a User 214A may locate a Smart Device at the location of transceiver 105 with an ATA 209B and interact with an App (or other executable code executed by a controller) that identifies a particular authorized area of work 217 which may also represent a TA based upon the Smart Device at the location of transceiver 105 being located in the ATA 209B. The App may present Agent credentials for a controller, software, automation, or other provider of access to Virtual Tag(s) 211,211A-211B.
The App may also present payor credentials for the User 214A (or other entity that authorizes payment for sale of materials, energy, services, or other saleable item or quantity to the User 214A or an entity associated with the User 214A).
In some preferred embodiments, the credentials are virtually presented to a known payment processor, such as a bank, a credit card company, online payment company (e.g., Venmo, PayPal, Zelle etc.) via a secure Internet connection or device specific app, thereby adding further security features. In this manner, the present invention provides for a payee for a transaction from within a specific TA for one or more of: a) a finite list of potential purchases; b) a finite list of potential vendors to purchase from; c) a capped amount of purchase contingent upon the Agent identification and the TA the Agent is in; d) unlimited purchase conditions with each purchase associated with the particular project or other accounting designation, wherein the accounting designation is associated with a particular TA; and f) unlimited purchase conditions and/or accounting variables based upon the TA and Agent credentials.
For example, a User 214A in an ATA 209B may execute an app that provides a user interface with user interactive devices enabling one or more of: the purchase, shipping, supply. lease and rental of one or more of: materials; services; utilities; equipment; supplies; food; space; real estate; or other purchasable item and have the purchase linked with a jobsite associated with one or more of: an ATA 209B; an architectural aspect 218; and a User 214A-214B. No card swipe, chip scan, near field communication or other locally interceptable transfer of data takes place; and the point of sale may be anywhere within an ATA 209B.
In some embodiments, an additional step may be included in a secure transaction according to the present invention. The additional step may include generation of a Virtual Tag 211 in RTA viewable from the ATA 209B. Use of the Virtual Tag 211B verification requires that a User be able to see the Virtual Tag 211B and interact with the Virtual Tag 211B. In some embodiments, a Virtual Tag 211B may occupy a congruent space in a user interface as an item in a visual representation (e.g., image data reproducing a physical area). The item may be, by way of non-limiting example, an item of equipment 213A-213C; personnel 214A-C; robotic agent 215; materials 216, authorized area; or other ascertainable item in a visual representation included in a user interface presented on a Smart Device at the location of transceiver 105.
A remote hacker or a hacker that was not in or very close to the ATA 209B would not be able to view and interact with the Virtual Tag 211B since the Virtual Tag 211B is assigned to a set of location coordinates that are unpublished to the User 214A except as an icon in an A/R interface. Similar processes may be utilized in other secure transactions that may, for example, involve access to protected digital content and submission of protected digital content.
In some embodiments, an action taken, or quantification of a condition on the worksite may be accomplished via a robotic Agent 215, such as an UAV or UGV, in such embodiments an alternate ATA 209B may be designated as an area for a specific action and an icon may be locatable by the robotic Agent 215, as well as by a User 214A overseeing the robotic Agent 215. The icon may include digital content related to an action to be performed by the robotic device 215 at a particular location. For example, the icon may include a type of material to be used; a fastener type; parameters of installation, time of installation; sequence of installation; values for variables related to installation (e.g., force, pressure, torque, thickness of material, rate of process used, etc.).
In another aspect, in some embodiments, a secure transaction may include one or more of: operation of various items of equipment 213A-213C; operation of a device 219, such as an automated lock that provides entry into a designated area or structure (such as a delivery area, equipment corral, commercial building, garage, parking area, recreation facility or fenced in area); association of digital content with a position of a design model, site plan, floorplan or other AVM; and access to a utility area. Utility areas may include, for example, an electrical power substation, a gas line control area, water supply area, wastewater area, Internet or other distributed network area, watershed area, or other utility area. A secure transaction may include a delivery, or simple access to the area via an ATA 209B. As with other secure transactions according to the present invention, a Virtual Tag Icon may be generated proximate to the ATA 209B (in this case viewable from the ATA 209B) such that User 214A interaction with the generated icon may be used to further verify an authorized User 214A is present at the designated area allocated as the ATA 209B. A utility area may also be equipped with an ATA 209C accessible via UAV and/or UGV.
While a construction site is illustrated, other outdoor, or combined outdoor and structure interior environments are within the scope of the present invention. Accordingly, a definable geospatial area, such as a recreation area; hunt club area; private land; Federal Bureau Land Management area, National Park, State, or local park, including land areas and/or water body areas may be designated to contain one or more ATA's 209B. One or more ATA's 209B may be associated with one or more Virtual Tag Icons to verify a User 214A and a location that may be referenced in an automated process for authorizing a transaction, which may include authorization to be present on the land included as a managed area, a delivery, a movement of items within the area, or other action. Areas that contain wildlife and/or human activity may also require authorization for activities monitoring movement of the wildlife and/or humans and/or equipment.

In some embodiments, an Agent 300 may position a smart device 305 including one or more transceivers and antenna arrays in a first position 301 proximate to a portion in a space of interest 310. The first position 301 of the Smart Device 305 may be determined and recorded, for example in terms of cartesian coordinates X, Y and Z, representative of three planes 302X, 302Y, 302Z. The Agent 300 may orient the smart device 305 in a general direction of the portion in space of interest 310. Positional coordinates may also include other known coordinate values, such as: polar coordinates and/or cylindrical coordinates.
A controller in an external system or in the smart device 305 may generate a directional indicator 303 (e.g., one or both of a ray and a vector). The directional indicator 303 may be directed towards a portion of a space of interest in which the Agent 300 would like to execute a secure transaction, such as interaction with a Virtual Tag 311 (e.g.: generation of a new virtual tag; modification an existing virtual tag; or receipt of digital content included in an existing virtual tag). Interaction with a Virtual Tag 311 may include one or more of: receipt of digital content associated with the Virtual Tag 311; associating digital content with the Virtual Tag 311; and conditions for access of the Virtual Tag 311.
In some embodiments, the vector may have a length determined by a controller that is based upon a distance to a feature of interest in space as represented in a model on the controller in the direction of the generated vector. The vector may represent a distance from the second position to the space of interest 310 along the axis defined by a line between the first position 301 and the second position. In contrast, a ray may include just a starting point and a direction.
In still other embodiments, a device with a controller and an accelerometer, such as mobile phone, tablet or other Smart Device 305 that includes a Transceiver, may include a user display that allows a direction to be indicated by movement of the device from a determined location acting as a base position towards a point in a direction of interest or representing a center of an RTA of the device. The movement may occur to a second location in an extended position. In some implementations, the Smart Device 305 determines a first position 301 based upon triangulation with the reference points. The process of determination of a position based upon triangulation with the reference points may be accomplished, for example via executable software interacting with a controller in the Smart Device 305, such as, for example by running an app on the Smart Device 305.
An array of antennas positioned at a user reference point may allow for the accurate receipt of orientation information from a transmitter. As discussed earlier a combination devices with arrays of antennas may be used to calculation a position. A single Node with an array of antennas can be used for orienteering and determining a direction of interest. Each of the antennas in such an array receiving a signal from a source may have different phase aspects of the received signal at the antennas due to different distances that the emitted signal passes through. The phase differences can be turned into a computed angle that the source makes with the antenna array.
In some embodiments, aspects of location determination and verification may be integrated with other security mechanisms (e.g., 306-309) that may implement processes that involve security specific protocols and hardware. For example, any of the wireless communications may also involve the use of a security processor, such as a chip to cloud security processor 306 and associated software and processes. According to the present invention, the chip to cloud security processor 306 and other chip to cloud technology 308 may interact with one or both of: a location coordinate generator 307 and a CPU Core 309 to further ascertain that a requested process involving digital content is being requested by an authorized Agent 300, from an authorized geospatial area and for an authorized purpose.
In some embodiments, methods, and devices for determining a direction that may be referenced for one or both of data capture and data presentation of a particular portion of the virtual representation of surroundings of a user. An Agent 300 may position a Smart Device 305 in a first position 301 proximate to a portion in a space of interest 310. The first position 301 of the Smart Device 305 may be determined and recorded. The Agent 300 may then relocate the Smart Device 305 to a second position in a general direction of the portion in space of interest. With associated position information obtained for the first and second positions a controller in an external system or in an associated Smart Device 305 may generate one or both of a ray and a vector towards the portion of a space of interest.
In some embodiments, the vector may have a length determined by a controller that is based upon a distance to a feature of interest in space as represented in a model on the controller in the direction of the generated vector. The vector may represent a distance from the second position to the space of interest 310 along the axis defined by a line between the first position 301 and the second position. In contrast, a ray may include just a starting point and a direction. In various embodiments, a vector may be referenced to define a volume of space that has a perimeter of a defined shape, such as a rectangle, circle, oval, square or other perimeter shape with a volume defined by the perimeter being extended through space in a direction and for a distance indicated by the vector.
In still other embodiments, a device with a controller and an accelerometer, such as mobile phone, tablet or other Smart Device 305 that includes a Transceiver, may include a user display that allows a direction to be indicated by movement of the device from a determined location acting as a base position towards a point in a direction of interest or representing a center of an RTA of the device. The movement may occur to a second location in an extended position. In some implementations, the Smart Device determines a first position 301 based upon triangulation with the reference points. The process of determination of a position based upon triangulation with the reference points may be accomplished, for example via executable software interacting with a controller in the Smart Device, such as, for example by running an app on the Smart Device 305.
An array of antennas positioned at a user reference point may allow for the accurate receipt of orientation information from a transmitter. As discussed earlier a combination devices with arrays of antennas may be used to calculation a position. A single Node with an array of antennas can be used for orienteering and determining a direction of interest. Each of the antennas in such an array receiving a signal from a source may have different phase aspects of the received signal at the antennas due to different distances that the emitted signal passes through. The phase differences can be turned into a computed angle that the source makes with the antenna array.
As illustrated in
In some examples, as may be used in orienteering herein, an Agent-supported device 314A may support receivers, transmitters or transceivers that interact with ultrasonic transceivers fixedly secured to a reference point position, such as via mechanical mounting within a room environment. An ultrasonic positioning system may have indoor positioning accuracy at centimeter, millimeter, and even sub-millimeter accuracy. Multiple ultrasonic Transceivers may transceive from an Agent-supported device to communicate with fixed reference point transceivers may transmit signals. Arrival of the sound transmissions may be accurately timed and converted to distances. In some embodiments, distance determinations may be improved with knowledge of temperatures in the environment containing the sound transceiving. For example, temperature may be measured at one or more of: an Agent-supported Smart Device, a Reference Point position, and an ambient environment.
In some examples, synced timing apparatus is able to generate a location of a stationary Agent to within centimeter accuracy using sonic wave transmissions and reception and preferably within several millimeters of accuracy. In addition, in some embodiments sensors are able to detect frequency shifts within the sonic emanations which may add information about the relative rate of movement of the Agent, which may then in turn allow for correction to the timing signals.
In some examples, a combination of radio frequency emissions and ultrasonic emissions may be used. For example, a complement of radio frequency emissions/receptions and ultrasonic of radio frequency emissions and ultrasonic emissions may be reconciled to generate more accurate location determination. In another aspect, a radio frequency signal may be used to transmit syncing signals that establish a time that ultrasonic signals are transmitted. Since, the electromagnetic transmissions may be orders of magnitude faster than sound transmissions, the electromagnetic transmissions relatively small time of travel from the Transceivers to the Agent may be negligible and therefore used as “zero-time” setpoints as received at the Agent-supported Transceiver. In such embodiments, a controller determining a location may use not only relative arrival times, but also a delta time between a radiofrequency transmission and ultrasonic transmission to determine a distance from a transmitting Transceiver. An array of such ultrasonic and/or radiofrequency transceivers provide increased accuracy in triangulating a location of the Agent.
In still further examples, RF communications may not only transmit a syncing pulse, but also transmit digital data about various aspects of a defined area, such as the defined area's identification, its relative and/or absolute location in space and other refinements. In some examples, data related to improved distance calculation may also be transmitted by RF communication such as temperature of the environment, humidity and the like which may influence the speed of sound in the environment as a non-limiting example. In some examples, such a system may result in millimeter level accuracy of position determination.
In some examples, the process may be iterated to refine the direction of each of the ultrasonic transmitters and maximize signal levels of the transmission which may provide additional information in the calculation of a position. RF and Wi-Fi transmissions may be used for data communications and syncing as have been described. In other examples, as an Agent-supported device 314A is moving, an iterative process may be used to track the Agent-supported device 314A moves through space. Stationary Agents may be tracked with submillimeter accuracy in some embodiments.
A direction dimension may be based upon multiple transceivers included in a Smart Device or a Smart Receptacle or via a movement of a Smart Device or Smart Receptacle while an Agent supporting the Smart Device or Smart Receptacle remains in a stationary position in relation to reference, such as a ground plane position. For example, a device with a controller and an accelerometer, such as mobile Smart Device, may include a user display that allows a direction to be indicated by movement of the device from a determined location acting as a base position towards a feature in the intended direction where the movement results in an extended position. In some implementations, the Smart Device may first determine a first position based upon triangulation with the reference points and a second position (extended position) also based upon triangulation with the reference points.
As described above, facing a mobile device towards an area in a Structure and movement of the mobile device in a particular pattern may be used to ascertain a specific area in space to be interpreted by various methods. In some examples, the leading edge of a smart device, or the top portion of the user screen (in either portrait or landscape mode of display) may be the reference for the direction pointed in by the user. If the smart device is held at an angle relative to the ground, in some examples, the angle formed by the perpendicular to the top portion of the user screen may be projected upon the ground and that projection taken as the indication of direction.

In some embodiments, one or both of the Smart Device 501 and the Smart Receptacle 502 incorporating Transceivers 503-510 may be rotated in a manner (such as, for example in a clockwise or counterclockwise movement 520, 522 relative to a display screen) that repositions one or more Transceivers 503-510 from a first position to a second position. A vector 526 may be generated at an angle that is zero degrees with a plane of a display screen 523 or perpendicular 525 or some other designated angle in relation to the smart device 501 and an associated display screen 523. In some embodiments, an angle in relation to the smart device is perpendicular 525 to a display screen 523 and thereby viewable via a forward-looking sensor (or other CCD or LIDAR device) on the smart device. In addition, a mirror or other angle-altering device may be used in conjunction with a CCD, LIDAR or other energy receiving device.
Movements of a Smart Device 501 equipped with an antenna array can be determined via relative positions of the antenna and/or via operation of an accelerometer within the Smart Device 501 or Smart Receptacle 502. Rough movement sense may be inferred with a single source to the antenna array. However, with multiple sources, the positional movement of each of the antennas can be used to sense many types of movements including translations and rotations.
A user may position the smart device 501 such that an object in a direction of interest is within in the CCD view. The smart device may then be moved to reposition one or more of the transceivers 503-510 from a first position to a second position and thereby capture the direction of interest via a generation of a vector in the direction of interest.
In some embodiments, movement of the Smart Device 501 and/or the Smart Receptacle 502 may not be desired and another method of indicating direction may be utilized, such as a value generated based upon a magnetic force detection device, such as a magnetometer included in the Smart Device 501 and/or Smart Receptacle 502. Registration of a magnetic force may be determined in relation to a particular direction of interest 524 and a determination of magnetic force referenced or provide a subsequent orientation of the Smart Device 501 or Smart Receptable 502. In some embodiments therefore, multiple modalities of wireless input may be used to determine a position of a Smart Device and direction of interest 524.
For example, a first wireless modality may be used to determine a structure in which a Smart Device 501 is located. Accordingly, the first modality may include a cellular transmission or GPS signals. A second modality of wireless communication may be used to determine a position within the structure. Appropriate second modalities may therefore include, one or more of UWB, Bluetooth, sonic, ultrasonic, LiDAR, or infrared modalities (or other modalities discussed herein). A third modality, such as a magnetic force, a movement of a device, a relative position of two or more antennas may be used to determine a direction of interest.
In some embodiments, the magnetic force detection device may be used combination with, or in place of directional movement of the Smart Device transceivers 503-510 to quantify a direction of interest to a user. Embodiments may include an electronic and/or magnetic sensor to indicate a direction of interest when a Smart Device 501 and/or Smart Receptacle 502 is aligned in a direction of interest. Alignment may include, for example, pointing a specified side of a Smart Device 501 and/or Smart Receptacle 502, or pointing an arrow or other symbol displayed upon a user interface on the Smart Device 501 towards a direction of interest.
A magnetic force detection device (sometimes referred to as a magnetic sensor) may detect a magnetic field particular to a setting that a Smart Device is located. For example, in some embodiments, a particular structure or other setting may have a magnetic force that is primarily subject to the earth's magnetic field or may be primarily subject to electromagnetic forces from equipment, power lines, or some other magnetic influence or disturbance. An initial quantification of a magnetic influence at a first instance in time may be completed and may be compared to a subsequent quantification of magnetic influence at a later instance in time. In this manner an initial direction of interest indicated by a position, orientation, pitch, and yaw of a Node, such as a Smart Device may be compared to a subsequent position, orientation, pitch, and yaw of the Smart Device.
In some embodiments, an initial position, pitch, and yaw of a Smart Device 501 may be described as a relative angle to a presiding magnetic force. Examples of presiding magnetic forces include, magnetic influences of electrical charges, Earth's magnetic field, magnetized materials, permanent magnetic material, strong magnetic fields, ferromagnetism, ferrimagnetism, antiferromagnetism, paramagnetism, and diamagnetism, or electric fields that are generated at reference nodes at known positions which may be locally used to indicate a direction of interest.
Smart devices may include electronic magnetic sensors as part of their device infrastructure. The magnetic sensors may typically include sensing elements deployed along three axis. In some examples, the magnetic sensors may be supplemented with electronic accelerometers, such as MEMS accelerometers.
In some examples the magnetic sensor may include a Hall effect sensor that is operative to measure a sensed magnetic field perpendicular to the body of the sensor via operation of the Hall effect sensor. In some examples, a Hall effect sensor may be built into silicon to generate a relatively sensitive sensing capability for magnetic fields. In some Hall effect sensors, electrons and holes flowing in a region of the silicon may interact with the regional magnetic field and build up on the fringes of the conduction region, thus generating a measurable voltage potential. In other examples, anisotropic magnetoresistance sensors may sensitively detect the magnetic field at the device as a significant change in resistance of structure elements in the device.
In still further examples, the magnetic sensor may include one or more giant magnetoresistance (GMR) sensors may detect the magnetic field. In some of these examples, the GMR sensors may detect a magnetic field with a current-perpendicular-to-plane (CPP) GMR configuration. In other examples, a current-in-plane (CIP) GMR sensor configuration may be used. The resulting three-axis magnetic sensors may perform a sensitive compass function to determine a direction of a specified portion of the Smart Device and/or an edge of the smart device relative to the local magnetic field environment. A specified portion of the Smart Device may be indicated via a user interface presented on a screen of the Smart Device.

As presented herein, a direction dimension may be based upon one or more of: a wireless position of two or more transceivers, a movement of a device, a magnetic force determination, a LIDAR transmission and receiving, CCD energy determinations and other assessments of an environment containing the Smart Device and/or Smart Receptacle. For example, a device with a controller and an accelerometer, such as a mobile Smart Device, may include a user display that allows a direction to be indicated by movement of the device from a determined location acting as a base position towards a feature in the intended direction where the movement results in an extended position. In some implementations, the Smart Device may first determine a first position based upon triangulation with the reference points and a second position (extended position) also based upon triangulation with the reference points.

In some embodiments, a portion of the 2D representation will be displayed in a user interface 606A based upon a virtual tag position 617 of the smart device 606 and a direction of interest 617A generated via wireless mechanisms and methodologies discussed herein. The wireless mechanisms and methodologies may include for example, one or more of: radio communications; magnetic readings (e.g., a compass reading); accelerometer readings; sonic readings; image recognition and the like.
In some embodiments, an Agent 600 may select one or both of: an area to be included in a user interface 606A; and a direction of interest via interaction with the user interface 606A. Interaction to indicate a direction of interest and/or an area to be included in a user interface display, may include, for example, dragging over an area of the user interface 606A; creation of a geometric shape, which may be a polygon or arcuate shape or combination of both; free hand movement; and selection of areas designation by a pattern of Virtual Tags 604 and/or IoT Tags 601-603 and/or Hybrid Tags 605. In some embodiments, for example, one or both of a direction of interest 617A and an area or a representation of a structure 618 may be defined in whole or in part via a tag (virtual, hybrid and/or virtual) that define different zones, quadrants, rooms, architectural aspects, structure features, or even flood zones, seismic zones, animal sanctuaries, dangerous conditions, or other subject.
Digital content associated with one or more of IoT Tags 601-603, Virtual Tag 604, Hybrid Tag 605; may include almost any content representable via a digital value or pattern, such as, by way of non-limiting example, one or more of: narrative, text, video, image, audio, uniform resource locator, IP address alone or in combination with a port and/or socket; and ecommerce vehicle.
In some non-limiting examples that relate to construction site management, a worker may be on site and instead of having a series of physical documents that must be carried and updated and deciphered as to their meaning and revision level and applicability to a particular worker, the worker or other Agent 600 may simply carry a Smart Device 606 and based upon the position of the Smart Device and a direction of interest 617A, a user interface 606A may display information specific to the Agent 600 via one or more of IoT tags, Virtual Tags 604, 607-616, and Hybrid Tags 605. For example, an HVAC worker may have included in a user interface 606A, data generated by an IoT Tag 601-603 with an electronic sensor that provides readings on one or more of: heat, humidity, water presence, air flow and the like. A plumber, electrician and/or a sheet rock worker may or may not be shown similar or same data on a user interface presented to them. A Hybrid Tag 605 may include a time and position of an IoT tag 601 at a time previous to a present time period and digital content generated by the IoT Tag 601 while the IoT Tag 601 at that time and position. As discussed herein, a position of the IoT Tag 601 may include a set of Cartesian Coordinates (e.g., X, Y, Z) and/or polar coordinates or cylindrical coordinates (including >angle and radius).
Similarly, an electrician may be shown wiring and electrical fixtures on the electricians User Interface 606A and a plumber may be shown piping and plumbing fixtures on the plumbers User Interface 606A. Accordingly, a user interface 606A may include content based upon an Agent that will interact with the user interface 606A and the position 617 and direction of interest 617A for the Smart Device 606.
In some embodiments, digital content included in a user interface 606A may be stored in a data receptacle (e.g., a data storage vehicle) and linked, such as, via a data file, relational database, index, ledger, blockchain, or other data association mechanism enabling specific digital content to be associated with coordinates that indicate a particular location, which may be referred to as a Tag location. In addition, the specific digital content may be associated with one or more Agents 600. A Smart Device 606 may also be associated with the Agent 600, and a position 617 and direction of interest 617A. An Area of Interest, and/or Radio Target Area may be based upon the position 617 and direction of interest 617A and an area shape and thereby include the location of the Tag. If the Area of Interest, and/or Radio Target Area does include the location of the Tag, then the digital content associated with the Agent may be included in a user interface 606A presented on the Smart Device 606.

In addition, in some embodiments, activation of an initial interactive area represented as a Virtual Tag 621-626 may bring a user from a first user interface 627A to a second or subsequent user interface. For example, a subsequent user interface may include information derived from a BIM model, AVM or other sophisticated resource normally requiring a proprietary interface.
In some specific embodiments, one or more of a Virtual Tag, IoT Tag and Hybrid Tag may be used to guide a robot or other unmanned vehicle (including, for example, one or both of an unmanned aerial vehicle and/or an unmanned ground vehicle or machine) to a location for performing an action; and/or confirm a location for performing an action. The action may be almost any procedure that the robot is capable of performing while deployed on a location. By way of illustration and non-limiting example, one or more of a Virtual Tag, IoT Tag and Hybrid Tag may be used to guide a robot or other unmanned vehicle may be guided to a person, such as a patient in an assisted living situation, rehabilitation, or medical care facility and assist the patient in a manner that the robot is designed. Wireless location and direction of interest as described herein may be combined with Virtual Tags and/or IoT Tag data to provide input to the robot as to a function to perform at a particular location for a particular patient.
In another example, a construction site robot may be guided to a position 622A within a structure 620 that corresponds with a Virtual Tag 622 and be provided with an instruction for an action to be conducted at the Virtual Tag position 622A. The action may be an action achievable by a robot or other automation engaged to receive instruction from the Virtual Tag 622. As illustrated, the instruction may include, for example to install sound proofing on the walls, or some subset of the walls the robot may access form the indicated Virtual Tag position 622A.
In some embodiments, a Virtual Tag may be created remotely by associating coordinates with digital content, On location, the Virtual Tag may be accessible as would any other tag based upon the location coordinates, such as via an interactive user interface.
According to the present invention, multiple modalities of wireless position determination may be utilized to provide an increasingly accurate location of the smart Device position 628 and direction of interest 629. For example, a satellite 630 communication modality, such as GPS may provide the smart Device position 628 determination accurate enough to determine an identification of a structure 620; and a radio transceiving such as an UWB and/or Bluetooth modality may provide a Smart Device position 628 and direction of interest 629 and also a Virtual Tag position 622A. Image recognition, LiDAR, laser, sonic, ultrasonic or other highly accurate modality may further guide a precise location for an action to be performed. By way of non-limiting illustration, in the construction site example, a radio transceiving such as an UWB and/or Bluetooth modality may provide a Smart Device position 628 and direction of interest 629 may be used to indicate a particular wall to be worked on by a robot, and one or more of Image recognition, LiDAR, laser, sonic, ultrasonic may be used to specify a precise location of an action, such as where to drill a hole, or place a beam or board.

In some embodiments, digital content may be transceived to an IoT Tag 633-634 and stored. Subsequently, an Agent 600B may transceive between a Smart Device 627 and the IoT Tag 633-634 to retrieve the information stored in the IoT Tag 633-634 that was downloaded from the satellite 630.
In another aspect, digital content generated on sites of remote locations 631-632 may be stored in a Node such as an IoT Tag 633-634 and transceived via a satellite uplink communication and from the satellite 630 conveyed to a distributed network, such as the Internet and/or a virtual private network.
Embodiments illustrated in
As with other settings, an Agent 600B in a remote wilderness location 632 may generate a Virtual Tag 636 by placing a Smart device 627 at a location 639-640 and associating a set of location coordinates with the location 639-640 of the Smart Device 627. The agent 600B may interact with a user interface 627B on the Smart Device 627 to acknowledge the set of location coordinates and associate Agent specified digital content with the set of location coordinates. Similarly, an IoT Tag 633-634 may generate data, or other IoT Tag 633-634 digital content and associate the digital content with set of location coordinates.
In a case where the IoT Tag 633-634 subsequently changes its location, a hybrid tag 641 may be left as an artifact from the previous presence of the IoT Tag 633-634 at that location. While such a capability may be useful in many scenarios and locations, it may be particularly important at remote locations 631-632 to track a presence of an Agent 600B at the remote locations 631-632 and information in the form of digital content that the Agent may be able to input into a system utilizing one or more of location based: Virtual Tags, IoT Tags, and Hybrid Tags.
While a Smart Device 627 is within remote locations 631-632 or proximate to such area of remote locations 631-632 (within transceiving distance to Reference point transceivers located therein); an Agent 600B may transceive with Reference Point Transceivers 101-104 to generate location coordinates and perform the actions described herein, including accessing digital content via oT tags 633-634, or virtual tags 636, and generating Virtual Tags 636 and/or hybrid tag 641.

At step 702 a location is designated via the wireless processes and using the apparatus discussed herein.
At step 703, a set of coordinates is associated with the designated location. Coordinates may include any grouping of alphanumerical values that is capable of indicating within a required accuracy range a location of the Agent. A required accuracy range may be contingent upon a modality of wireless communication used to generate the coordinates.
At step 704, a direction of interest from the designated location is generated. The direction of interest may be generated, for example, via generation of a vector intersecting a position of a Smart Device supported by the Agent. Generation of the direction of interest may reference, by way of non-limiting example, locations of reference point transceiver, angle of arrival of radio spectrum energy; angle of departure of radio spectrum energy; values generated by a magnetic sensor, image data recognition processes, LiDAR, ultrasonic measurements, and the like.
At step 705, a shape of a directional area associated with the direction of interest may be designated. The shape of a directional area may include for example an area congruent with a radio a target area or other geometric area. Non-limiting examples of geometric areas may include areas definable as a frustum; conical area; an area with a square profile' an area with a rectangular profile, an area with another polygonal profile; an area with a circular profile, an area with an oval profile; and an area with a complex geometric shape profile, combining linear, arcuate, and angular aspects.
At step 706, digital content is designated that is accessible from the designated location in the direction of interest, and in some embodiments within the area of interest.
At step 707, an interactive user interface is generated that is accessible via a smart device or other automated device having a controller and a display.
At step 708, user interactive areas within the interactive user interface are associated with coordinates, and at step 709, the coordinates are associated with specific digital content.
At step 710, the Agent will activate a user interactive area associated with specific coordinates such that at step 711, the digital content associated with the coordinates is presented on the user interface. Other actions may also be triggered by the Agents activation of an interactive area, such as control of an item of equipment, activation (or deactivation) of an alarms state, generation of an electronic message, or almost any action activatable via an electronic console.

As illustrated, a portion of the RTA 801 may flatten out 801a in response to a ground plane, wall, partition, or other obstruction encountered. A Node 806 may be located on or within a surface that makes up a relevant obstruction and the Node 806 may appear to be along a perimeter of the RTA 801. Similarly, a Virtual Tag may be associated with location coordinates that appear on or within a floor, wall, partition, or other article acting as a radio frequency obstruction and thereby appear to be a part of the obstruction, however, since it is virtual, the Virtual Tag will not affect the physical properties of the obstruction. Essentially, a Virtual Tag may have location coordinates that correspond to anywhere in the physical real-world. In some examples, a software limit or setting may limit location coordinates of Virtual Tags to some distance from a base position or a distance from a designated position, such as a location of a designated Physical Tag, Reference Point Transceiver, or other definable position.
In addition to obstructions, a topography of an environment within an RTA 801 may also limit wireless conveyance of energy within an RTA 801 to an energy-receiving Sensor 804. Topography artifacts may include, for example, a terrain, buildings, infrastructure, machinery, shelving, or other items and/or other structures that may create impediments to the receipt of wireless energy.
Energy 803 received into the energy-receiving Sensor 804 may be used to create aspects of a user interface that is descriptive of the environment within the RTA 801. According to the present invention, environmental aspects, Nodes 806, Tags (both physical Tags and Virtual Tags) and the like may be combined with user interactive mechanisms, such as switches or other control devices built into a user interactive device and included in a user interactive interface. For example, energy levels received into an energy-receiving Sensor 804 may be combined with location coordinates of Physical Tags and/or Virtual Tags and a user interactive device may be positioned in an interactive user interface at a position correlating with the position coordinates and be surrounded with a visual indicator or the received energy levels.
In this manner, a single user interface will include a static image representative of received energy levels at an instance in time; a visual representation of a location(s) of Physical and/or Virtual Tag(s), and devices with user interactive functionality. In some embodiments, the devices with user interactive functionality may be positioned at a location in the user interactive interface correlating with the position(s) of the Physical and/or Virtual Tag(s).
This disclosure will discuss RTAs 801 that are frustums of a generally conical shape, however, RTAs 801 of other volume shapes are within the scope of the invention. For example, if an energy-receiving Sensor 804 included a receiving surface that was a shape other than round, or had multiple receiving surfaces, each of a round or other shape, the RTA 801 associated with such an energy-receiving Sensor may have a shape other than a frustum of generally conical shape.

Some embodiments include an RTA 807 that varies according to a type of energy-receiving Sensor 804 receiving a corresponding type of energy. For example, an energy-receiving Sensor 804 that receives energy in a lower bandwidth may have an RTA 807 that extends a greater distance than an energy-receiving Sensor 804 that receives energy in a higher bandwidth. Similarly, some energy-receiving Sensors 804 may be affected by forces outside of the RTA 807, such as a magnetometer which may be sensitive to signal interactions around all of the WCA 800, and an RTA 807 associated with a magnetometer may accordingly be the same as the WCA 800.
By way of non-limiting example, an RTA 807 for a CCD-type energy receiver may be represented as a frustum with an expansion angle of approximately 60 degrees in shape. Accordingly, the RTA 807 subtends only a portion of the universal WCA 800.

A user interface based upon quantified energy in an RTA 807A, may present a representation of energy within the respective RTA 807A as quantified by an energy-receiving Sensor in a Smart Device 802. Energy levels of other three-dimensional spaces within the WCA 800D may be quantified by energy receivers and presented in a user interface by directing energy from a selected three-dimensional space into the energy receivers and thereby defining a different RTA 807A. In this manner, energy levels may be quantified from essentially any area within the WCA 800D and represented as part of a user interface. Quantified energy levels may vary based upon a receiving Sensor. For example, a CCD Sensor may quantify visible light spectrum energy, and a LIDAR receiver a broad spectrum, an infrared receiver may quantify infrared energy levels, and energy-receiving Sensors. A particular feature present in a particular portion of the electromagnetic spectrum quantified by an energy-receiving Sensor may have a unique physical shape which characterizes it, and which may be associated with a corresponding virtual-world aspect and Tag associated with the location.
In some examples, as has been described, quantification of energy levels associated with aspects of the physical world may be for one or more of: characterizing an RTA 807A by quantifying energy levels and patterns existing at an instance in time; determining a location and/or orientation of a Smart Device 802 or other Node, such as Node 806; and verifying a location and/or orientation of a Smart Device 802. Various embodiments include energy levels associated with aspects of the physical world may be communicated by the Smart Device 802 to a remote controller for further processing, and the remote controller may communicate information back to the Smart Device or to another user interface. Information communicated from the controller may include, for example: an orientation of physical and/or virtual aspects located within the universal RTA in relation to the Smart Device; and quantified energy indicating of or more of a topographical feature, a surface temperature, a vibration level, information associated with a Virtual Tag, information associated with a physical Tag, sensor data, or other information associated with the RTA 807A.
A view of an RTA 807A (Radio Target Area) may be a relatively small portion of the entire wireless communication area (WCA) that surrounds a Smart Device. An area of energy to be quantified by a sensor (sometimes referred to herein as the Radio Target Area) may be displayed surrounded by the WCA 800D.

A location of a real-world Tag or Virtual Tag may be in either RTA 813, the WCA 811 or external to both the RTA 813 and the WCA 811. Examples of Tags outside the RTA 813 and within the WCA 811 include Tags 815-819. An example of a Tag in the device RTA is Tag 820. A Tag located external to of the WCA 811, and the RTA 813 includes Tag 821.
In some examples, a display on the user's Smart Device may illustrate image data captured via a CCD included in a Smart Device. Portions of the image data captured via a CCD may be removed and replaced with an icon at position correlating to a position in space within the RTA 813. The icon may indicate of a Tag 821 located within the RTA 813, or at least the direction in the RTA 813 along which the Tag 821 may be located at an instance in time. In addition, an area of a user interface portraying the Icon may user interactive device such that when the device is activated, the Smart Device is operative to perform an action.
The actual positions of the Tags in real-world space (or the digital equivalent in the real-world space) may be stored and maintained in a database. Positions of physical Tags may be determined via techniques based upon wireless communication and be updated periodically. A period of update may be contingent upon variables including, user preference, Tag movement, change in environmental conditions, User query or other variable that may be converted into a programmable command. In another example of some embodiment, an Agent may interact with a user interface and understand the presence of Tags that are outside of the RTA 813 and adjust one or both of a position and direction that the Smart Device to cause the Smart Device to be positioned such that the RTA 813 encompasses a position of the Tag of interest.

Smart Device 901 may have its position and direction of orientation determined using the orienteering methods described herein, with reference to one or more Reference Point Transceivers 908 A-B. The position may be determined relative to a Base Node, such as Reference Point Transceiver 908A. The Base Nod may operate as an origin in a coordinate system associated with Structure 906 and its surroundings. A position-determination process may be aided with reference to transmitter 907, which in some embodiments, may be a Reference Point Transceiver. In this example, transmitter 907 is positioned proximate to the Structure 906.
A receiver on Smart Device 901 may be operative to receive a wireless logical communication from transmitter 907. This communication may be in one of a variety of modalities, such as Bluetooth, ultra-wideband (UWB), radiofrequency, infrared, ultrasound, etc. Based upon the signal, Smart Device 901 may transmit a database query based upon a determined set of coordinates of transmitter 907, a set of coordinates of the Smart Device 901, the RTA 905, or other position and direction relevant variable.
If the database contains an entry comprising a set of coordinates (as a data structure) and the set of coordinates define a point within displayable distance to the set of coordinates of transmitter 907, then the user interface 920 may display an interface that includes an interactive area 904 that manifests a Virtual Tag (such as an icon or other definable area) in context to a virtual structure 903 representative of the physical structure 906. In this way, a user of Smart Device 901 may be alerted to the presence of information associated with structure 906 in which the user may be interested.
In some embodiments, inclusion of an interactive area 904 on the user interface 902 may be contingent upon an Agent operating the Smart Device 901 presenting appropriate credentials and/or permissions to access digital content made accessible via the interactive area. Still further appropriate credentials and/or permission may be required to ascertain that an interactive area exists. For example, an image displayed on a user interface may include imagery descriptive of item of equipment or a person. A user with proper credentials may be presented with a user interface that includes an interactive area 904 that manifests a Virtual Tag, such as an icon or outline of imagery descriptive of an item of equipment or a person; while a user who has not presented proper credentials may not be made aware of the existence of such an interactive area, nor the content included in the Virtual Tag associated with the interactive area 904.
In another aspect, in some embodiments, an interactive area 904 may only display if Smart Device 901 is in active communication with a specified Wi-Fi network, or if the Smart Device 901 his in communication with at least one of a specified Node or Nodes. Communication with a Node may include, for example, wireless communication via a wireless modality, such as, one or more of: UWB; Bluetooth, infrared, sonic, or other modality discussed In other embodiments, interactive area 904 may display on any user interface 902 (if the RTA 905 includes transmitter 907), but further functionality may be based upon successfully responding to a security challenge. A security challenge may include, for example, a biometric measurement, inputting a password, correctly input an answer to a question, a gesture made with the Smart Device, a gesture made in communication with a sensor integrated within or with a Smart Device (such as, for example, motion of hand(s) in front of a camera, or motion of a hand wearing a Smart Ring or a wrist wearing a Smart Wristband).
In some embodiments, the appearance of interactive area 904 may change based upon variables, such as, one or more of: the position of the Smart Device 901; the identity of user or Agent; if the interactive area 904 is related to a query and/or query response; if the interactive area 904 is within an RTA 905 or based upon some other dynamic. For example, if the user has a certain UUID, and the database includes a message specifically intended for a user with that UUID, then the interactive area 904 or an icon may flash to indicate the presence of a message. This message may be displayed textually, visually, audibly, or by a hologram. Similarly, the database may record one or more instances in which the Smart Device 901 is accessed via a query from a Smart Device. Access via a query may be associated with a time stamp. If data related to structure 906 has changed since a previous time stamp, then interactive area 904 may be presented in a highlighting color (such as, for example be presented in red or other color) to indicate that a change has been detected. In addition, digital content may be appended to any content already in the database, such as additional alphanumeric annotation, an audio file, an image file, a video file, or a story file.
In some embodiments, in response to activation of an interactive area 904 (such as a click, screen touch, voice command, gesture, etc.), additional functionality may be provided via the Smart Device 901 or other item of equipment. For example, selecting interactive area 904 may display digital content related to Structure 906. Alternatively, activating the interactive user device associated with interactive area 904 may generate a control panel, which may allow the user to control aspects relating to sensors or other electronics within structure 906. For example, upon confirmation that Smart Device 901 has the appropriate permissions, selecting interactive area 904 (or other activation of the interactive area 904) may allow the user to turn off the lights within structure 906. Still other embodiments allow for activation of an interactive area 904 to be a prerequisite to operation of equipment located within the RTA 905 or other defined area.
An interactive area 904, may be incorporated into a user interface in almost any manner conducive to a user activating the interactive area 904. For example, a user interface that recreates a visual of a physical area, such as, by way of non-limiting example: an image (or video) based upon a CCD sensor array; a two dimensional representation of a physical area (such as a floorplan, site plan or architectural drawing); and a three dimensional representation (such as a CAD model, AVM; or Augmented Reality model) may include interactive areas that include areas of the image data, integration of one or more of: an icon, an outlined image area, a highlighted image area, an image area with a changed appearance (e.g. change in hue or color), integration or overlay of an image (e.g. a logo, emoticon, or other device).
The Smart Device 901 may also display other functional buttons on its user interface 902. In some examples, one such function may be to show displays of the sensor in the context of the universal RTA 905 surrounding the user. By activating the functional button, the user may be presented with a set of options to display the universal RTA 905.
According to the present invention, an interactive area 904 may be used to retrieve digital content, and/or to store digital content for subsequent retrieval. Digital content may be associated with one or more sets of position coordinates (e.g., cartesian coordinates, polar coordinates, and/or cylindrical coordinates). A user interface 902, AVM and/or two dimensional representation of a structure or geospatial area may be produced that allows the digital content to be accessed based upon the associated coordinates. The retrieval of the digital content is persistent in the sense that it may be retrieved, and new digital content may be added for so long as an underlying infrastructure enabling determination of coordinates used to access and/or place digital content within a coordinate framework exists.

The Tag 931-932 may be located at a physical location within or outside of the RTA 932 (is illustrated). Selection of the Tag (sometimes referred to activating the Tag 931-932), a menu 933 may display. Amongst the various information such as text, imagery, video content and the like that may be displayed an identification of the Tag 934, associated textual information and data 935 as well as functional buttons 936 may be displayed on the user interface and may be used by the user to activate additional function including new display layers, content integration and control function such as in a non-limiting sense a control to revert to a previous menu display.
In some examples, a Smart Device may function as a Tag. The Tag functionality may include providing location-related information as broadcasted digital content. In providing such broadcasted digital content, the Smart Device tab may employ numerous forms of security protocols for the protection of the information and authorization of its use which may include sign-in/password protocols, sharing of encryption keys and the like. In similar methods, a central server may provide content related to a Tag and may manage security protocols and the like where a Smart Device acting as a Tag may merely share an identification phrase that a user could use with applications running or connecting with the central server could use to be authorized for additional content. Location may be determined by the various means as described herein including wireless communication with position Nodes by GPS, Cellular, Wi-Fi, Ultrawideband, Bluetooth and the like. If the Smart Device is operating in a mesh Node, the mesh could communicate within Nodes relative and absolute location information which the Smart Device may share as its role as a Tag. In addition to location, other sensor data at the Smart Device such as temperature, vibration, sensor imagery, LiDAR scan imagery, sound sensing.
In addition to real-world data, the Smart Device Tag may also provide virtual content associated with itself and its connected environment. The Smart Device may provide content stored within its memory devices and may provide dynamically calculated results of processing on content stored in its memory devices. The virtual content may also correspond to a user interface of the Smart Device Tag that may be used to initiate or authorize function of the Smart Device including real-world activities such a communication via internet protocol, text, phone, or video.
In some embodiments, an energy-receiving Sensor may receive energy associated with a LiDAR transmission and/or other functionality involved in LiDAR scanning which can be used to interrogate the local environment for physical shapes. In a Smart Device Tag function, the Smart Device may stream its video and scanning data directly or through a server model. Some Smart Devices may be configured to operate as a smart security monitoring systems and may provide the video, topographic, audio, and other sensor streams as Tag related content. There may be numerous manners that a Smart Device could function as a Tag in an environment.
A Smart Device with either a single- or multiple-sensor system may also have a LiDAR scanning capability or other three-dimensional scanning capability. The Smart Device may utilize a number of systems to refine and improve its accuracy in determining the location that it is at. In an example, a Smart Device may utilize a GPS or cellular system to get an approximate location of the device. In a next step, a user may initiate the Smart Device to take a series of image and scanning data acquisitions of its environment. For example, the user may move the phone by hand to different directions while maintaining their feet in a fixed location. The phone may use one of the orientation methods as have been discussed to determine its orientation as it is moved to different vantage points. The Smart Device may either process those images and compare against a database in its memory, or it may communicate the data to a server to do the comparison. With an approximate location, the orientation information, and the streams of video and/or topographic information, a calculation may be performed to match the image/topographic information to a more exact positional location. In alternative examples, the device may use the image and/or topographic information to determine the orientation of the device itself.
In some examples, the Smart Device may act as a receiver of one or multiple types of wireless energy input. For example, the acquisition of data based upon a visual light spectrum (approximately 380 to 700 nm wavelength) may be modelled as spatially-characterized electromagnetic energy. Electromagnetic energy in the visible band may enter a focusing lens and be focused up an array of devices. The devices may be CMOS-active pixel sensors, CMOS back-illuminated sensors, or CCDs, as non-limiting examples, to receive the energy and convert it into spatially-arrayed pixel data.
In some examples, the Smart Device may have an energy-receiving Sensor incorporated or attached which may quantify energy levels for frequencies outside the visible spectrum. Any optics employed in such sensors may be different from the previously discussed CMOS and CCD Sensors since some of those energy receiving devices may have filters or lenses that absorb wavelengths outside of the visible spectrum. Sensors with infrared capabilities may have specialized optics and may use different materials for the CMOS and CCD elements—such as indium gallium arsenide-based sensors for wavelengths in the regime of 0.7-2.5 μm.
Alternatively, entirely different sensing elements, such as bolometers, which sense temperature differences of the incoming radiation, may be employed for longer wavelengths in the regime of 7-14 μm and may include filters that remove other wavelengths. A display of an infrared Sensor, which senses incoming energy in the infrared band, may be rendered on a typical visual display, but the colors of such displays may have no direct physical meaning. Instead, a color scheme may be instituted to represent different infrared wavelengths with different visible colors. Alternatively, the colors may be used to represent different intensities of infrared energy received across bands of infrared wavelengths.
In some examples, a Smart Device may both project and receive energy. For example, a Smart Device may scan the topography of its surroundings by use of LiDAR. In LiDAR, a laser may be used to emit energy into the environment. The energy may be emitted as pulses or continuous trains, and the light source may be scanned across the environment. Light emitted from the Smart Device may proceed into the environment until it is absorbed or reflected. When it is reflected and subsequently received at the Sensor, the transit time can be converted to distance measurements of the environment. Many different wavelengths of light may be used to scan an environment, but numerous factors may favor certain choices such as invisibility to human/animal eyes, safety, absorption by the airspace surrounding the user and the like. Atmospheric gases may absorb significant amounts of infrared transmissions at certain frequencies; therefore, for LiDAR to be effective in the infrared spectral region, certain bands of emitted frequencies may be favored. A standard LiDAR system may operate at a band from 900-1100 nm infrared wavelength or at a band centered at approximately 1550 nm. As discussed previously, select optic components and materials may be useful for these wavelengths and the detectors may have improved function based on materials such as “black” silicon, germanium, indium phosphide, gallium arsenide, and indium gallium arsenide as exemplary detector materials.
In an example, a laser light source may be rastered across a dimension of forward looking positions of a Smart Device, which may be represented by a conic section or Radio Target Area in front of the Smart Device. As the light is raster across the surface it can address, it may be pulsed on or off. As the light travels out along a collimated path, it may interact with a surface and a portion of the intensity may be reflected backwards.
A resulting reflected ray may come back to the Smart Device and be received by a Sensor in the device. Since the emitted light source may be orders of magnitude more intense than the surroundings, reflected light may dominate a background intensity and the signal detected may be compared with the time of the leading edge of the laser pulse. The repeated acquisition of the timing signals in the various directions can be used to form a point cloud that represents the distance to reflective features from the Smart Device.
As mentioned previously sound may be reflected off of surfaces and the transit time may be used to characterize a distance between a focused ultrasonic transducer and a reflective surface. In similar manners, points or lines of focused sound emissions may be pulsed at the environment and a sensor or array of sensors may detect the reflected signals and feed the result to a controller which may calculate point cloud representation or other or topographic line representations of the measured surface topography. In some examples, ultrasonic focused and scanned soundwaves in the frequency range of hundreds of megahertz may result in small, focused sources whose reflections may be detected by magnetic or piezoelectric sound transducers as non-limiting examples.
A Smart Device may have numerous different types of energy-collection devices which may characterize data values with spatial relevance. As mentioned before, infrared imaging may be performed on some Smart Devices, and a user may desire to view a spatial representation of the infrared imaging that represents the data as it may appear if the user's eyes could perceive the energy. In some examples, data values for the wireless energy sensing of infrared energy may be assigned color values and displayed in an image format. For examples, low levels of infrared energy, which may relate to colder temperatures in the imaged regions, may be assigned blue color values, and high levels of infrared energy, which may relate to warmer temperatures, may be assigned red color values. Other color assignments to data values may be used. A legend for the conversion of the color values to the data values may be provided.
In some examples, the data descriptive of spatially descriptive energy levels quantified by an energy-receiving Sensor data may be portrayed in a user interface. In some user interfaces, representations based upon spatially representative energy levels of different wavelengths may be aggregated or otherwise combined in one or more related user interfaces. Such a combination may allow a user to understand the regional nature of various quantified energy.
In some examples, a user interface may allow for display of the positional location image points. In some examples, a location of a pixel element chosen by a user may be converted to a real-world location within the RTA which may be represented in Cartesian coordinates (X,Y,Z) or in other coordinate systems such as polar coordinate systems involving angles and distances as discussed previously. In some examples, topographic data obtained by scanning an area with an RTA may be used quantify topography within the RTA. A user interface based upon such quantified energy levels may include virtual presentations of the quantified energy levels from different perspectives and may allow for coordinate grids (Cartesian or other) to coordinate placement of facets of a user interface based upon combinations of energy level data, Tag locations and perspective relevance.
In some examples, distinct structures within the RTA may be highlighted and assigned positional coordinates. In some examples, this may occur by image processing directly, in other examples a user interface may allow for a user to pick items/regions of interest in an RTA presentation.
In other examples, real and virtual Tags may exist within the RTA. A physical Tag may include a position Node, another Smart Device, or any device with communication capability that can communicate with either a position Node or with the Smart Device of the user directly. Such physical Tags may be located in numerous manners. In some examples, the physical Tag may have a direct determination of its location either because it is stationary and has been programmed with its location or because it has the capability of determining its own position with the various methods as have been described herein. In other examples, a physical Tag may be able to communicate with Nodes such as Reference Point Transceivers and a location may be determined based upon an exchange of data, such as timing values, in the wireless communications. A Node may also be functional to determine, store and communicate a location of other Tags. The Smart Device of the user may gain access to the locations of Tags, either because they are publicly available or because the user has established rights digitally to obtain the information from some or all of these physical Tags.
There may also be virtual Tags that are associated with positional coordinates. The distinction of these Tags over physical Tags is that there may be no physical presence to the virtual Tag. It may be a digital or virtual-world entity that has an association with a real-world positional coordinate. Except for this distinction, a virtual Tag and a real-world Tag may behave similarly with respect to their association with a physical coordinate.
In these examples, an interactive user interface based upon energy levels and Tags located with an RTA may have icons associated with the placement of Tags. The user interface may include an icon positional designation and a graphic to indicate the presence of a Tag. It may be apparent that, in some cases, multiple Tags may lay along a single direction from a given Smart Device location and RTA, and thus multiple icons may be included within a user interface in close proximity. The user interface may indicate multiple Tag icons by color changes, blinking or other indicators. As an RTA is changed, Tags along a same perspective may resolve into different directions for Tags with different positional coordinates.
The Tag icon may indicate to the user a digital functionality associated with a real-world or virtual Tag. For example, the icon may allow a user to choose the functionality of the icon by moving a cursor over the icon and making a keystroke or mouse click or for touch screens by pressing the display location of the Tag icon. The choosing of the Tag icon may activate user interface dialogs to allow the user to control subsequent functionality. In cases of superimposed Tag icons on a same pixel location in a user display, a first functionality may allow the user to choose one of the multiple Tag icons to interact with. In some examples, a Tag icon may be displayed with an associated ID/name and a user may select the icon with voice commands rather than physically selecting the icon as described previously. Displays of these Tags may follow similar protocols as have been discussed in reference to

The wireless receiver may be a Smart Device sensor, including a CMOS active pixel sensor, a CMOS back illuminated sensors, CCD, or a LIDAR apparatus, including a solid-state/MEMS-based LIDAR. The wireless receiver may comprise an array or other plurality of other wireless receivers. The wireless receiver may be operative to receive the wireless energy into an array of an appropriate dimension for subsequent display (possibly after processing) on the Smart Device. For example, where the wireless receiver is a Sensor, the Sensor may be operative to translate the wireless energy into a two-dimensional array.
At step 1002, a pattern of digital values is generated based upon receipt of wireless energy into the wireless receiver. This pattern of digital values may be based on one or more qualities of the received wireless energy, including its intensity, spatial dispersion, wavelength, or angle of arrival. The pattern may be placed into an appropriate array. For example, if the display of the Smart Device is a two-dimensional display, then the pattern of digital values may comprise a two-dimensional representation of the image data received. In some embodiments, the pattern of digital values may be based on an aggregated set of values from an array of receivers. For example, if the basis of the digital values is the intensity of the wireless energy received into the receiver, then the digital value assigned to a given entry in the array may be based on a weighted average of intensity of wireless energy received at a plurality of the receivers in the array. Optionally, at step 1003, the wireless receiver may receive the wireless energy as an analog signal (for example, if the wireless receiver is a black-and-white sensor or an unfiltered CCD), and convert the analog signal to digital values through filtration or other analog-to-digital conversion. The set of digital values within the Radio Target Area is the Digital Radio Target Area.
With the Smart Device wireless receiver's Radio Target Area determined, the Smart Device's position should be determined as well, along with the positions of any items of interest in a given space. Collectively, the Smart Device and the item of interest may comprise wireless Nodes. Accordingly, at step 1004, coordinates representative of a wireless Node may be determined relative to a base Node. These coordinates may be determined in any appropriate coordinate system (such as Cartesian, polar, spherical polar, or cylindrical polar) and may be determined via RTLS or the orienteering-triangulation methods with various wavelengths or modalities, such as ultra-wideband, Bluetooth, etc. Additionally, the coordinates may be determined using an angle of arrival or angle of departure of a signal to or from the base Node, along with the distance from the base Node. By way of non-limiting example, this could produce a dataset that correlates the coordinates of three elements with the identities of those elements: {(0,0,0), BaseNode; (1,1,1), SmartDevice; (2,2,2), ItemOfInterest}. While this example may be used throughout the following discussion, it is understood to be non-limiting, as a given space may include a plurality of items of interest. Note that, in some embodiments, the Smart Device itself may become a dynamic database entry with a continuously (or periodically) updating set of coordinates. This may be useful in allowing a plurality of Smart Devices engaged with the system at the same time to interact with one another.
At step 1005, the position of the Base Node is determined relative to the defined physical area. In exemplary embodiments, this may include establishing the Base Node as an origin in the coordinate system and determining vectors from the Base Node to boundaries and items of interest (i.e., the distance from the Base Node and the direction from the Base Node to the boundaries and items of interest). In some examples, the Base Node may have an established reference relative to a global coordinate system established.
At step 1006, a Target Area is generated within a controller of the Smart Device. The Target Area may be the set of coordinates (relative to the Base Node) within the Radio Target Area of the wireless receiver. The Target Area may be limited by physical boundaries of the given space, such as walls, floors, ceilings, occlusions, etc. The Target Area may also be limited by distances that various types of signals may travel. For example, a sensor of audio signals may not be able to practically pickup signals over a background noise level that originate more than 1000 feet from a user position, purely as an example. In such a case, the Target Area for such signal types may be limited to that dimension.
At step 1007, respective positions of one or more wireless Nodes within the Target Area are determined. These positions may be determined relative to the physical Target Area or the Radio Target Area. The determination may be made with reference to the dataset discussed at step 1005, or it may be made dynamically based upon one or more Base Nodes and/or the Radio Target Area. Moreover, the determination may additionally be based on receipt of a wireless signal into the Smart Device from the wireless Node. This signal may indicate a position using the orienteering methods described herein.
At step 1008, a user interface may be generated on the Smart Device based upon the pattern of digital values generated at step 1002. The user interface may comprise a plurality of pixels, wherein each pixel comprises a visible color based upon the pattern of digital values generated at step 1002. For example, if the digital values were based upon receipt of visible light into the wireless receiver (e.g., a sensor), then the display may reflect a reasonably accurate color photograph of the Radio Target Area of the wireless receiver. If the digital values were based upon an intensity of received light from, for example, LIDAR, then the display may reflect a scan of the Radio Target Area. In some embodiments, the pixel may include an intensity of energy received into the receiver. In this way, aspects of the Radio Target Area characterized by an intensity of energy may be emphasized. For example, this may produce a LIDAR relief of an area or a heatmap of an area.
At step 1009, an icon may be generated in the user interface. Preferably the icon will be placed at a position relative to data quantifying received energy levels. In some embodiments, the icon location in a user interface will be indicative of a position of a Tag (Virtual or Physical). This position may be quantified via positional coordinates, such as Cartesian Coordinates, Polar Coordinates, Spherical Coordinates, and the like. The icon may be based upon an input from a user, stored data, quantified environmental conditions or other criteria related to an aspect of the Radio Target Area.
For example, an icon may indicate information about an Item of Interest located at a given set of coordinates within the Radio Target Area or Digital Radio Target Area. In another embodiment, the user may indicate on the display a position in which the user wishes to place an icon and add information about an Item of Interest (thus creating a new entry in the database, which may be populated with the coordinates of the indicated position). Moreover, the icon may change colors based upon the pattern of digital values. The icon may be overlaid on top of the display. The icon may resemble the letter “I,” a question mark, a thumbnail, or any other suitable image from a library. In some embodiments, the icon may change depending on one or more attributes of its corresponding database entry. For example, if the icon located at (4,4,4) relates to a restaurant menu, then the icon may resemble the letter “i” or a thumbnail of a menu. On the other hand, if this database entry is modified so that the corresponding database entry is a message, then the icon may update to a picture of an envelope.
In some embodiments, the icon-generation step may be based upon an inquiry to a database that uses the Digital Radio Target Area as an input. For example, upon generation of the Digital Radio Target Area, an associated set of coordinates in one or more dimensions may be generated. This may then be submitted to a database. An associated display may be as illustrated in
Continuing with the example from step 1004, the Digital Radio Target Area may comprise the set of coordinates: ([1.5,10], [1.5,10], [1.5,10]). In this example, the database may return information about the Item Of Interest, but not about the Base Node. The Digital Radio Target Area may update when the Smart Device position changes, or by user input, the Digital Radio Target Area may remain static after a certain instance in time.
Continuing with
At step 1011, user-interactive functionality may be associated with the pixels comprising the icon. This may allow the user to “select” the icon by means of an input device (e.g., mouse, touchpad, keyboard), touchscreen, digital input, etc. Upon selection, the icon may be operative to interact with the user in one or more ways, including: displaying a message intended for the user (by text, audio, video, hologram, etc.); requesting credentials from the user to verify permissions (e.g., a password), displaying information about an item associated with the icon, prompting the user to update information about an item associated with the icon, etc. The user-interactive functionality may display static information (e.g., dimensions of the item), display dynamic information (e.g., an alarm state or sensor information relating to the item; for example, if the item is a refrigerator, internal temperature may be displayed), or produce a control panel that allows the user to issue control commands (e.g., remotely operating an automated apparatus by resetting an alarm state, taking remedial action based upon a sensor state as described herein, etc.) or to issue menu control commands such as to invoke a different user interface or screen of a user interface.
This may be useful in geospatial applications, or in procedurally generated activities. For example, a first user may generate a positional designation on a user interactive device, such as, for example an augmented-reality display to leave a narrative, icon or other input associated with the first use. Additionally, the same or another user may log positional coordinates and upload an image that could be displayed submitting a database query including those coordinates. Entry of the coordinates and essential credentials may provide access to the content associated with the positional coordinates.
At step 1012, the preceding steps may be integrated by generating a display comprising the user interface, the icon, and at least some of the associated user-interactive functionality. In embodiments, in which a plurality of Smart Devices are themselves part of the database, this may allow various users to send messages, images, etc. to each other.
At step 1013, detection of movement of the Smart device may cause a branch back to step 1005. Based upon that movement of the Smart Device, a defined physical area from which wireless energy is received (i.e., the Radio Target Area based upon the Target Area) may be changed. The movement may be detected using input from wireless communications, magnetic field sensors, an accelerometer, feature-recognition software, or other similar apparatus and algorithms. In other examples, the position of the Smart Device may be dynamically obtained using any of the techniques of position determination, such as triangulation with reference nodes. Here, too, a change of position detected in this manner may cause a branch back to step 1005. The Target Area may be based upon the position of the Base Node, the relative positions of the wireless Nodes, and the Smart Device.

The bolded entries in the database shown in
The ActionType variable may include any action for which interactivity with an icon may be desirable. In
Action may relate to any action that a sensor, electronic device, or other apparatus connected to the database may take. For example, Action may include changing a temperature, measuring a temperature, turning off lights, activating an emergency sprinkler system, opening a door, etc. In some embodiments, prior to taking the Action, a password may be requested as part of the permission check.
Directions may show a user how to navigate (using, in exemplary embodiments, orienteering methods) from the current position to a desired position. For example, upon scanning an entry on a map, virtual arrows may be generated to guide the user to a chosen store.
The ActionAttributes may have attributes based on the ActionType. For example, if the ActionType is Information or Message, then the ActionAttributes may be a text string or a stored audiovisual file containing the message. Similarly, if the ActionType requires a sensor or other electronic device to take an Action, then the ActionAttributes may include a command or subroutine to affect such an Action. In the example shown here, the ActionType Directions comprises an ActionAttribute that includes a command to the Smart Device (i.e., show directions in the form of green arrows).

In some examples, the user may be prompted to choose a desired coordinate system for the display at step 1203. In other examples, a user interface of the system may have a setpoint function which the user may invoke to gain access to user settable parameters which may include they type of coordinate system to use, such as for example Cartesian or spherical coordinates.
In still further examples, the system may decide to default to a particular coordinate system depending on the nature of the type of data its positional reference devices may be obtaining or providing.
At step 1204, if the coordinate system was chosen as Cartesian coordinates, the system may utilize triangulation amongst multiple reference point transceivers. Alternatively, at step 1205 if the coordinate system was chosen as polar coordinates, the system may utilize positioning systems that utilize angles and distances involved in transceiving and location. In either event, at step 1206, the position of a Sensor attached to the smart device of the user may be determined. In some examples, the system may have multiple and redundant location system. A combination of such position determinations may result in superior accuracy of an aggregated position result. Accordingly, at optional step 1207, a wireless position determination may be performed with the smart device to establish a verification of the position of the Smart Device and the Sensor attached. Referring now to step 1208, a direction that the sensor is facing in may be determined. Although there may be a number of different manners of determining orientation as have been described herein, in an example, the orientation may be determined based upon wireless transmission and/or wireless verification.
Referring now to step 1209, an energy-receiving Sensor included in the Smart Device or in logical communication with the Smart Device may be used to quantify energy levels perceivable at the position and in the direction of the Smart Device. The resulting quantification may depend on aspects of the Sensor device, but the resulting data will quantify a characteristic for the RTA.
In some embodiments, an optional step 1210 may be performed by an element of the system such as the smart device or a server in communication with the Smart Device. The element of the system may compare one or more of position information, orientation information and the image data itself to calculate an estimate of whether the RTA angle has changed for the sensing element.
In general, at step 1211, the RTA of the Sensor device used to capture the image in step 1209 may be quantified. In an optional step 1212, coordinates relating to the instant RTA of the image may be established. In some examples, this may relate to a range of three-dimensional coordinates that are addressed by the RTA of the Sensor element. In general, at step 1213, the system may look up, or in some cases generate, location coordinates for Tags that are determined to be within the quantified RTA. In some database systems that the system may have access to, real-world or virtual-world tags may be tracked in a coordinate system with a certain origin.
If the current origin established at step 1201 is offset from a particular database related origin, then one or both the coordinate system values may be converted to each other to align their respective origins. At step 1214, the Tags in an aligned coordinate system may have their positions compared to the current RTA and a selection for the set of Tags that are within the RTA may be made.
In some alternative examples, a display of all Tags that are authorized for access to the user regardless of whether they are in the RTA may be made using associated aligned coordinates as discussed in reference to step 1213.
Referring now to step 1215, in an example, the Smart Device of the user may be used to generate and display a user interface to the user based upon the captured image and the associated tag icons within the RTA. These associated Tag icons may have at least the functionality as has been discussed in reference to

For example, bandwidths may include those associated with UWB, Wi-Fi, Bluetooth, ANT, ultrasonic, infrared, and cellular modalities of communication. In general, unless otherwise constrained by physical modification such as the use of a directional antenna, or the presence of radio frequency interference from a physical object (such as objects with significant metallic content; objects with high water content; electrical fields; etc.), a WCA 1302 may include spherical area(s) emanating from one or more transceivers and/or transceiver antennas operated by the Smart Device 1301.
As discussed extensively herein, and in patent applications referenced by this application, the location of the Smart Device 1301 may be determined based upon wireless communication to and/or from the Smart Device 1301; and described via a coordinate system, such as via generation of Cartesian coordinates, or other coordinates such as: polar coordinates, spherical coordinates, and cylindrical coordinates. Modalities of wireless communications that may be referenced to generate location coordinates may include one or more of: RTT (round trip time), time of flight, RSSI (received signal strength indicator); angle of arrival, angle of departure, and other methods, equipment and modalities as have been described herein.
With the location of the Smart Device 1301 determined, a location of the WCA 1302 may be extrapolated based upon the location of the Smart Device and a range or transceiving distance the Smart Device may be capable of.
According to the present invention, a portion of the WCA 1302 may be selected as a radio target area (RTA) 1312 from which the Smart Device 1301 may receive specific bandwidths of electromagnetic radiation. In preferred embodiments, the RTA 1312 may include a frustum expanding outward in a conical shape from one or more energy-receiving Sensors 1309 included in the Smart Device 1301. The frustum shaped RTA 1312 may overlap with a portion of the generally spherically shaped WCA 1302. Other shapes for an RTA 1312 are also within the scope of this specification.
In some embodiments, a shape of the RTA 1312 may be based upon receiving capabilities of the one or more energy-receiving Sensors 1309 incorporated into or in logical communication with the Smart Device 1301. For example, an energy-receiving Sensors 1309 with a charge coupled device (CCD) or complementary metal oxide semiconductor (CMOS) receiver may have a single plane receiving surface and be best matched with a frustum of a generally pyramidal or conical shape. Whereas an energy-receiving Sensors 1309 with multiple receiving surfaces (e.g., with multiple CCD and/or CMOS devices) may be arranged to enable a more complex shaped RTA 1312.
In some preferred embodiments, a direction of interest 1311 may intersect the RTA 1312. As discussed herein, the direction of interest 1311 may be represented by a ray or vector 1311A and 1311B. In addition, the direction of interest 1311 may be represented as a direction of interest area, such as a frustum defined by multiple rays or vectors, 1311A and 1311B, In various embodiments, the direction of interest 1311 area may encompass the RTA 1312 or be a subset of the RTA 1312.
A direction of interest 1311 may be determined for example via the methods and devices described herein and in referenced patent applications and may be associated with a direction based upon a ray or vector indicative of a direction of interest 1311, a direction based upon a magnetic field sensor, an accelerometer, a light beam, correlation between two Tags or Nodes, Agent gestures, or other Smart Device recognized apparatus and/or method.
One or more transceivers 1303-1305 (typically included within a Smart Device, Tag, or Node) may be located within an area defined by the RTA 1312. According to the present disclosure, a position of the transceiver 1303-1305 may be determined and a user interactive mechanism may be generated at a position of the transceiver 1303-1305 within a graphical user interface emulating aspects of the RTA 1312 on the Smart Device 1301 or another user interactive interface screen (not shown, and perhaps at a site remote to the RTA 1312).
According to the present disclosure, some portion of the RTA 1312 (which may include the entirety of the RTA 1312) may be portrayed on an Agent interface 1310, including, in some embodiments, a human-readable graphical user interface (GUI). The interface 1310 may include a representation 1313 of a particular level of electromagnetic energy received via the energy-receiving Sensors 1309 and associated with a particular area of the RTA 1312. For example, energy levels of an infrared wavelength that has emanated from or reflected off of an item in the RTA 1312 and received via an infrared receiver in the Smart Device 1301 may be used to generate a heat map type interface display. Similarly, energy that has emanated from or reflected off of an item in the RTA 1312 in the 400 nm to 700 nm range and been received via a charge-coupled/or CMOS image sensing device in the Smart Device 1301 may be portrayed as a human visible image of items in the area included in the RTA 1312.
Other embodiments may include a point cloud derived from electromagnetic energy bouncing off of or emanating from items included in the RTA 1312 or a series of polygons generated based upon a LIDAR receiver in the Smart Device 1301. An Agent interface 1310 may be presented in a modality understandable to an Agent type. For example, an interface presented to a UAV or UGV may include a digital pattern and an interface presented to a human Agent may include multiple pixels or voxels generating a pattern visible to a human being.
The wireless location methods and apparatus described herein may be deployed in conjunction with one or more Transceivers 1303-1305 or Tags and/or Nodes 1306-1308 located with the WCA 1302 to generate location coordinates for the one or more Transceivers 1303-1305 or Tags and/or Nodes 1306-1308. A controller or other device operating a processor may determine which one or more Transceivers 1303-1305 or Tags and/or Nodes 1306-1308 located within the three-dimensional space included in the RTA 1312 based upon a) the location of the one or more Transceivers 1303-1305 or Tags and/or Nodes 1306-1308; and b) the location of area included in the RTA 1312.
In another aspect of the present disclosure, in some embodiments, some energy levels may not be represented in the Agent interface 1310. For example, in some embodiments, energy levels reflected off of a particular item may not be included in the Agent interface 1310. Other embodiments may only represent energy levels that have reflected off of selected items within the RTA 1312 thereby emphasizing the presence of the selected items and ignoring the presence of other items within the RTA 1312.
As described above, some portion of the RTA 1312 may be portrayed on an Agent interface 1310, including, in some embodiments, a human readable graphical user interface (GUI), as a point cloud derived from electromagnetic energy bouncing off of or emanating from items included in the RTA 1312 or a series of polygons generated based upon a LIDAR receiver in the Smart Device 1301. An example of such a representation is shown in
In this example, Virtual Tags 1403 and 1404 are created by the Smart Device by methods described herein and icons may be present on the GUI to identify the position of the Virtual Tags 1403 and 1404. The Virtual Tags 1403 and 1404 may, for example, represent various locations of interest in the RTA 1400, such as an object of interest or an exit or entrance The icons associated with the Virtual Tags 1403 and 1404 may be engaged or “clicked” or otherwise activated to be made operational; for the Smart Device to receive (e.g., retrieved from a database) additional information associated with the object or location of interest.
For example, if the object of interest is a statue, clicking on the icon associated with the Virtual Tag 1403 associated therewith may provide information regarding the statue, such as the history, origin, and the like. If, for example, the Virtual Tag 1404 is associated with an exit of the room, clicking the Virtual Tag may provide information on what is present in the adjacent room, or where the Smart Device is in relation to exiting the building, or any other desired information.
In some embodiments, mathematical data associated with a LIDAR rendering, such as parameters of triangles formed by various LIDAR points 1405-1406 within an associated RTA may be stored and a relative position of a smart device with the RTA 1400 may be determined based upon the recognition of similarities of the LIDAR point 1405-1406 patterns. A resolution of laser scanning involved in generation of data based upon LIDAR techniques may influence a number of date points within a selected RTA, but in general, pattern recognition and determination of an orientation of a smart device based upon LIDAR data may be much more efficient, than, for example image data based pattern recognition. In addition, the LIDAR based patterns may be formed in a “fingerprint” of an RTA, wherein it would be very rare, if not impossible to replicate the LIDAR point patterns at two disparate locations. Therefore, recognition of a point pattern may be used to identity a location of a particular RTA.

IoT sensors may be associated with transceivers and combined into a unit for quantifying conditions present at location, such as, for example a Shade™ Multi Sensor unit 1802 and/or a Shade Action Box 1803. A Shade Action Box 1803 will be associated with interactive controls linked to the user interface that allow for wireless of a structure aspect, such as a water turn off valve, a door lock, HVAC control, electrical on/off and the like.
Specific icons each associated with a disparate IoT sensor may be displayed with associated logos in a specified user interactive area 1809. Icons 1809a, 1809b may be associated with one or more of: fire, power, power surge, power outage, temperature, water, humidity, vibration and almost any condition quantifiable via an electronic or electromechanical sensor.
Interactive areas 1804-1806 may provide user control of aspects of the user interactive interface. For example, a calibration interactive area 1804 provides a user with control of functionality that allows the user to align A/R sensor data, such a visible light wave data and/or infrared image data to be aligned with an icon 1801-1803 or other designated user interactive area.

There may be numerous techniques that the system of transceivers and a radio position tag may be used with to determine positions by triangulation. In some examples, a distance from a transceiver to the radio tag may be determined by the measurement of the strength of the signal which is related to the distance the signal has travelled. In other examples, timing signals may be used to determine the precise time it takes for a signal to transit the distance. In still further examples, the angles of arrival of signals from or to the transponder may be used in combination to determine a location. Thus, the first position location 1905 may be determined by making at least three determinations of distance or angles between a radio position tag at first position location 1905 and the four transceivers (1901-1904).
It may be appreciated, that all four of the determinations may be made and can be used to calculate a position. In a real world environment, there may be a number of factors that lead to difficulties in obtaining a position or angle measurement with precision. In a first example, the positioning system may be installed in an interior location with walls, equipment, occupants, and other elements formed of materials that may interact with the radio signals (or other position signals such as infrared, laser, and ultrasonic signals as non-limiting examples. Scattered signals from walls may cause multiple signal paths which may cause confused signal determination. Depending on the location of the first position within the space of interest, one or more of the signal paths from the transceivers to the first position tag may experience signal degradation from one of the causes.
The positioning system may utilize all four of the signals to determine that one of the three signals could be omitted to improve the “goodness” of a position determination. Both the instantaneous signal path determination as well as the time progression of a signal path determination may factor into the rejection of a particular signal path measurement. Accuracy of position determination may be improved by sampling numerous times. In some examples, ultrawide band transmission protocols may be used to make position determination with relatively low energy consumption and good signal to noise aspects. Ultrawideband protocols may use extremely narrow (nanosecond) pulses which may allow for improved discrimination of multipath signal arrivals. Many different frequencies may be utilized for high degrees of sampling which can improve the accuracy.

In some examples, advantages may be obtained by establishing systems with larger numbers of transceivers.

Position tag 1910A may transceive a wireless communication to and/or from the 8 transponders and each of these paths may be used to determine the location. The statistical combination of additional transponder paths will implicitly improve the accuracy of measurements. In some embodiments, a system including the reference point transceivers 1901A-1907A is trained with known positions from time to time or a set periodic basis to remove static or systematic errors such as may occur in the location of a given position reference point transceivers 1901A-1907A.
In some embodiments, dynamic aspects of an environment in which the reference point transceivers 1901A-1907A are located may affect performance and accuracy of transceiving of wireless communications, such as for example changing a timing aspect associated with such transceiving.
For example, a human occupant of a space or an object that is placed transiently into a location may create an obstruction 1920A to line of sight path measurements such as the illustrated obstruction 1920A. The location determination system may detect the presence of an obstruction by a number of means such as a reduced signal strength over historical levels relative to other signal strengths at other transceivers. In some examples, interference by an obstruction 1920A may result in a distance or angle determination of the signal path D5 that is entirely inconsistent with the determination of position from some or all of the other paths D1-D4 and D6-D8.

According to the present invention, he smart device 2101A may include integrated wireless position devices 2102A-2109A and/or wireless position devices 2102A-2109A in a smart receptacle 2100B may provide a directional indication, such as a directional vector 2110A, without needing to move the smart device 2101A from a first position to a second position since a directional vector may be determined from a relative position of a first wireless position devices 2102A-2109A and a second wireless positional device wireless position devices 2102A-2109A.
In preferred embodiments, a position of the Smart Device 2101A may be determined based upon wireless communication with one or more Reference point transceivers 2111-2114. As described herein, a position may be determined based upon timing of wireless transmissions, such as via TDOA methodologies understood in the industry, and/or a time involved in a wireless communication and an angle of arrival and/or angle of departure for the wireless transmissions.
In other exemplary embodiments, distances may be triangulated based on measurements of wireless strength at two or more points, such as a strength of a wireless WiFi transmission. In the case of a WiFi transmission, a wireless signal may propagate outward as a wave, ideally according to an inverse square law. Ultimately, the crucial feature of the present invention relies on measuring relative distances at two points. In light of the speed of WiFi waves and real-time computations involved in orienteering, these computations need to be as computationally simple as possible. Thus, depending upon the specific application and means for taking the measurements, various coordinate systems may be desirable. In particular, if the smart device moves only in a planar direction while the elevation is constant, or only at an angle relative to the ground, the computation will be simpler.
A position may be described in reference to coordinates descriptive of a location, one such an exemplary coordinate system includes a cartesian coordinate system including an X,Y,Z position and other embodiments, may include a polar coordinate system. One example of a three-dimensional polar coordinate system is a spherical coordinate system. A spherical coordinate system typically comprises three coordinates: a radial coordinate, a polar angle, and an azimuthal angle (r, θ, and φ, respectively, though a person of ordinary skill in the art will understand that θ and φ are occasionally swapped).
By way of non-limiting example, suppose Point 1 is considered the origin for a spherical coordinate system (i.e., the point (0, 0, 0)). Each WiFi emitter e1, e2, e3 can be described as points (r1, θ1, φ1), (r2, θ2, φ2), and (r3, θ3, φ3), respectively. Each of the s (1≤i≤3) represent the distance between the WiFi emitter and the WiFi receiver on the smart device.
In some embodiments, the orienteering occurs in a multi-story building, in which WiFi emitters may be located above and/or below the technician. In these embodiments, a cylindrical coordinate system may be more appropriate. A cylindrical coordinate system typically comprises three coordinates: a radial coordinate, an angular coordinate, and an elevation (r, 0, and z, respectively). A cylindrical coordinate system may be desirable where, for example, all WiFi emitters have the same elevation.

In some examples, a controller determining a position may default to either a first point 2201 or a second point 2202 (additional points may also be calculated and used according to the methods presented in this disclosure) or a mathematical combination of the first point, second point (and any additional points) locations. A vector 2203 may be generated and a direction of the vector may be used as an Agent 2204 defined direction of interest.
A hierarchy of the first point 2201 to the second point 2202 may be specified to generate a starting point of the vector (e.g., first point 2201) and an intersecting point (e.g., second point 2202), a magnitude may be generated based upon a model of a position of the Agent 2204. A generated direction may be inverted by swapping the hierarchy of the first point 2201 and the second point 2202.
One or more of radio frequency and sound frequency transmissions, emissions, reflections, absorption, and detections may be used as input into a controller for determining a location of the first point 2201 and the second point 2202 and generation of a direction of interest.

In some embodiments, each transceiver 2210-2213 may in turn include multiple transmitters and/or receivers 2214-2217. The multiple transmitters and receivers 2214-2217 may operate on a same or different frequencies. Different frequencies may be within a same bandwidth, such as for example UWB bandwidth, or the different frequencies may be across different bandwidths, such as, for example an UWB and a WiFi bandwidth. In some embodiments a single transceiver 2210-2213 may thereby operate on multiple different frequencies. In other embodiments, different transceivers 2210-2213 may operate on a same or different frequencies. The multiple transceivers 2210-2213 may be operative to implement simultaneous or sequenced transmitting and receiving.
In some embodiments, some, or all of the multiple transmitters and/or receivers 2214-2217 may be incorporated into a transceiver device. The multiple transmitters and/or receivers 2214-2217 may also include an antenna 2220 with a same or different physical characteristics. For example, different antenna may be tuned to a same or different frequencies. In some embodiments, tens, hundreds or more antennae may be incorporated into a device in order to enable redundant communications and improve quality of a wireless communication.
Wireless communication may be accomplished for example via bandwidths associated with one or more of: Bluetooth; UWB; WiFi (including RTT Wi-Fi); Ultrasonic; and infrared communications. Transceivers used in transceiving may include antennas 2220 that are directional and/or omni-directional. Antennae 2220 may be tuned similarly or tuned differently. Transceiving may be accomplished simultaneously, in timed sequence and/or based upon occurrence of an even. For example, a sensor may transceive on a predetermined timed schedule and also transceive following the occurrence of an event, such as a sensor reding that exceeds a threshold.
As illustrated in
In some examples, mounting (either permanent or temporary) will include fixedly attaching a Reference Point Transceiver 2210-2213 to a position and may be made to one or more of: a ceiling within the defined area, a wall mount; a stand mount; a pole; or integrated into or otherwise connected to an electrical receptacle. In some examples, a reference transceiver 2210-2213 may be mounted at a calibrated location within the defined area 2200B and act as a coordinate reference location.
The Reference Point Transceivers 2210-2213 may be placed in logical communication with a controller (such as via a distributed communications system, wireless or hardwired), the controller may cyclically receive logical communication from one or more transceivers supported by an Agent located within the defined area 2200B while simultaneously monitoring the reference location. A Reference Point Transceiver 2210-2213 may be useful for calibrating various aspects of wireless communication between a Reference Point Transceiver 2210-2213 and an Agent supported Transceiver 2218-2219, aspects may include, for example variables in communication relating to one or more of: environmental condition such as humidity, temperature, and the like; as well as a variation in transceiver power levels, noise levels, amplification aspects and the like.
There may be numerous sources and causes of noise in a radiofrequency environment and/or a sound frequency environment (such as ultrasonic) that may come into play when using a Reference Point Transceivers 2210-2213 and an Agent supported Transceiver 2218-2219 that operate in one or more of: WiFi bandwidth; Bluetooth bandwidth; ultrawide band; ultrasonic or similar technology. For example, in an indoor environment walls, structures, furniture, occupants, HVAC settings; particulate in the air (such as smoke or steam) human traffic; machinery movement; and the like may create a complex and dynamic environment where radiofrequency logical communications reflect and are absorbed. Reflections, particularly multiple reflections, may cause spurious logical communications where the time for the logical communication transmission may be inappropriately long.
Accordingly, in some embodiments, a controller may benefit from receiving many data from multiple closely sequenced logical communications included in transmissions/receptions between Reference Point Transceivers and Transceivers supported by an Agent. Examples of multiple logical communications include less than ten samples to billions of samples per second. A large number of logical communications may be averaged or otherwise mathematically processed to determine a localization. Mathematical processing may include less consideration (e.g., weight, or removal) of logical communications outside of an otherwise closely associated data set. Other mathematical processing may include a mean, an average and a median of data included in the logical communications.
Systems with Transceiver counts of as few as six and sampling frequencies in the hundreds of billions of samples per second have been demonstrated to localize Transceiver locations with sub-millimeter accuracy. High sampling rates may require specialized data acquisition capabilities including advanced filtering systems, ultrafast digital to analog converters and the like. Fundamentally, the more samples that are collected per unit of time a more accurate a position determination may be.
A wireless positioning system (such as, WiFi, UWB, Ultrasonic and Bluetooth) with high positioning accuracy may be used for determination of a direction of interest using transceivers sized to be unobtrusive in a defined area 2200B and/or to be able to be supported by a human Agent or an automation Agent capable of traversing the defined area 2200B.

Linking between a smart device, such as a smart phone 2230, and an ancillary position determining device 2231-2234 may be accomplished, for example via a hardwire connection, such as a lightening port or USB, mini USB type connector, Bluetooth, ANT, near field communications and the like. A smart watch 2231 (one example of an ancillary position determining device 2231-2234) that may be worn on an Agent's arm, a wand 2234 may be held in an Agent's hand, similarly, a ring 2232 may be worn on a finger and a tag 2233 may be incorporated into a badge, a button, an adhesive backed patch, a clip, or a wide variety of attachment mechanisms. Each ancillary position determining device 2231-2234 may include one or more Transceivers capable of communicating with a Reference Point Transceiver to generate logical communications from which a position may be calculated.
The Agent's smart phone 2230 and an ancillary position determining device 2231-2234, may each have one or more Transceivers and may be used with the methods and apparatus described herein to determine a first point and a second point. The first point and the second point may be used for generating a vector indicating a direction of interest (as discussed above). Other combinations of devices may be used, such as those illustrated in

The devices shown as examples may allow a single hand to be used to indicate position and direction. Various other devices that may include transceiver capability may be used in similar manners. A user may have one hand occupied holding a tool or sensor or may be otherwise occupied and can still indicate a desired direction of focus. In the example of a wand 2234, the user may press a button, switch, or engage other activation mechanism, such as a capacitive discharge device on the wand to indicate that the orientation of the wand is at a desired input condition.
Transceiver devices may be operative to employ various methods to improve accuracy of location determination, including but not limited to varying a frequency of transmission and reception of logical communications; varying a pulse pattern transmission and reception of logical communications, and varying intensity of emissions used in transmitting a logical communication.
In some embodiments of the present invention, Agent supported Transceivers and ancillary position determining devices 2231-2234 may communicate bursts of logical communications that include timing information. A delay of logical communications between the transmitter and the receiver may be converted to a distance measurement and a combination of a number of such logical communications may be used to triangulate the position. In some examples, the smart phone 2230 and an ancillary position determining device 2231-2234 may transmit the timing logical communications which the mounted transceivers receive and process for a distance determination. In other examples, an ancillary position determining device 2231-2234 smart phone 2230 may receive logical communications and determine timing delays and associated distances. Results of distance determinations may be communicated to controller, such as processing devices located at a smart device. A suitable controller may be located at one or more of the Transceivers or at a location remote to the Transceivers and connected by a communication network.
There may be many physical properties that may be used to make localization measurements/determinations. In an example of another type of sensing system an Infrared based sensor and camera system may be used to determine localization and orientation.

A second area containing one or more transceivers 2301 and 2302 may be used as indicators that will be detected by directional apparatus, such as an infrared camera. A user may direct a pointer 2300 in a direction of interest and engage an activation mechanism, such as a switch, or engage in a motion to indicate the time to obtain the position and direction orientation. For example, an agent may activate a switch to activate a Transceiver 2301-2303 and partake in logical communication with a Reference Point Transceiver 2307. In some embodiments, the logical communication may be manifested as a pattern of light. A controller may be supplied with the pattern of light transmitted as well as Reference Position information and generate a direction of interest.
According to the methods of the present invention, position points P1-P4 may be generated based upon the logical communications between the Reference Point Transceiver 2307 and the Transceivers 2301-2303 supported by an Agent. A vector 2308 may be generated based upon the position points P1-P4. In addition, a smart device 2304 may also communicate with the Reference Point Transceiver 2307 and a position point P5 associated with the smart device 2304 may be generated.
In some embodiments, a vector 2309 may be generated based upon the position point P5 of the smart device 2304 and a position point P1-P4 generated based upon logical communications with Transceivers 2301-2303 located on or within the extension apparatus 2306.

It is understood that an accelerometer 2344 does not need to be incorporated into a smart phone and may be directly fixed to an attachment fixture 2342 or fixed to a vibration integrator 2341 or fixed to a structural component 2340.
Vibrations present in the structural component may be indicative of a state of functioning of equipment included in the structure (not shown in
In some embodiments, a user, such as a service technician, may install an accelerometer into the attachment fixture for the specific purpose of taking an accelerometer reading. A smart device 2343 may run an app that records a time and place and vibration pattern received. The vibration pattern may be compared with a known set of vibration patterns and a condition of the structured may be ascertained from the comparison. The time date and vibration pattern may be transmitted to a server and aggregated with other sensor readings.
In another aspect, in some embodiments, a second accelerometer 2344A may be used to introduce a vibration pattern into the structural component 2340. The second device may include a second attachment fixture 2342A that establishes vibrational integrity between the second accelerometer 2344A in a second smart device 2343A and a second vibration integrator 2341A. The vibration pattern introduced may include a known frequency and amplitude. In some embodiments, the vibration pattern will include a sequence of frequencies and amplitudes, wherein different frequencies and amplitudes will be effective in diagnosing or otherwise indicating an underlying causation for a pattern of vibration. The second accelerometer 2344A and the first accelerometer 2344 may be synchronized via executable software such that the first accelerometer will detect the vibrations introduced by the second accelerometer 2344A. Any discrepancies between what was introduced by the first accelerometer 2344 and the first accelerometer 2344 may be indicative of a state of the structure.
For example, introduction of a frequency pattern into a beam that is sound may transmit well through the beam and be detected with minimal variations from the frequency pattern that was introduced. However, a beam that is cracked or has rot within it may not convey the frequency pattern to the first accelerometer or convey the frequency pattern with significant distortion and/or diminutions in amplitude.
A history of sensor readings associated with a particular structure and/or group of structures may be stored and referenced to assist in interpreting a cause for a particular vibration pattern.
Vibration sensors may be installed and recorded in as built data or added to a structure in a retrofit. Some commercial sensors (such as the Fluke 3561 FC Vibration Sensor) may be associated with vendor supplied software for ease of retrofit implementation.
According to the present invention, accelerometers or other vibration sensors are deployed in specific locations and tracked in a structure according to the respective sensor location. In addition, a relative position of a particular sensor position is tracked relative to other sensors (vibration sensors or sensors for monitoring different modalities of ambient conditions). The present system includes an AVM that may store and make available to a user and/or to AI applications which structural components are in vibrational communication with a particular sensor. Various sensors include underlying piezoelectric, accelerometers of other technologies.
Embodiments also include a sensor programmed to reside in a lower power states and to periodically “wake itself up” (enter a higher powered state) to take a reading and transmit the reading. Sensor readings may be correlated with different types of wear, damage, failure, or proper operation of components included in a structure. The AVM may track location and may rank a likelihood of a component responsible for a particular vibration pattern detected by a sensor. The ranking may be based upon proximity, mediums available for communicating the vibration pattern (such as a beam traversing a significant portion of a structure, but which provides excellent mechanical communication for the vibration).
Some embodiments also associate a sensor reading of vibration with a type of motion likely to cause such a reading. For example, some readings may include a linear component and a rotational component (such as operation of a washing machine during certain cycles). Patterns of normal and abnormal operation may be recorded and deciphered via programmable software on a controller.
In another aspect, a pattern of sensor data that denotes spikes of linear data may be associated with a human being walking. Overtime, a controller may track sensor reading patterns and associate a particular pattern with the walk of a particular person.
It is also within the scope of the invention to track and analyze a set of data associated with a primary signal and additional sets of data (secondary, tertiary etc.) tracking harmonics of the primary signal. The AVM may also track sets of data associated with simultaneous, and/or closely timed readings received from multiple sensors and associate an amplitude, sequence, delay, or other attribute of the data sets relative to each other to provide input as to a location of a source of the vibration. Additionally, vibration sensors may include axis within the sensor. For example, two axis and three axis sensors may have a direction of each axis included in the AVM and used in analysis of a vibration pattern.
The present invention also provides simple and fast procedures for the provision of directions of a User or a sensor to a source of vibration based upon analysis of readings of one or more sensors via the X. Y and Z location determination and directional ray or vector generation methods described herein.
Disparate types of sensor may also provide disparate data types that are useful in combination to determine a source of sensor readings. For example, a vibration sensor reading indicating erratic motion may be combined with an increased temperature reading from a sensor proximate to an item of equipment. The combined sensor readings may assist in an analysis of a cause of the sensor readings.
In still another aspect, one or more sensor readings may be correlated to a life expectancy of an item of equipment, such as for example a heating Ventilation and Air Conditioning (HVAC) unit. By way of non-limiting example, an ammeter sensor reading measuring an electrical draw of an HVAC unit may be quantified upon deployment of the unit. The initial readings may act as a baseline of a unit in excellent operational condition. A similar baseline reading may be taken via an accelerometer measuring a vibration generated by the HVAC unit. Still other sensor readings may include airflow, temperature, humidity, or other condition. Over time, a change in one or more senor reading values may indicate some wear and move the HVAC equipment item into a “normal wear but operational” status.
Still further along a time continuum, one or more sensor readings may indicate a pending failure. For example, a current required to run the unit may be measured by the ammeter sensor and indicate an increased draw in electrical current. Likewise, airflow may decrease, and temperature may increase, and other sensors may provide additional evidence of a pending failure. Finally, a failed unit may generate a very high temperature reading and ammeter readings may increase to a level of sufficient electrical current draw to trip an electrical breaker, thereby indicating a failure.
According to the present invention, any of the sensor readings (or all, or some subset of all sensor readings) may be referenced to generate an alert. Following the alert, remedial action may be taken.

The wireless receiver may be a Smart Device sensor, including a CMOS active pixel sensor, a CMOS back illuminated sensors, CCD, or a LIDAR apparatus, including a solid-state/MEMS-based LIDAR. The wireless receiver may comprise an array or other plurality of other wireless receivers. The wireless receiver may be operative to receive the wireless energy into an array of an appropriate dimension for subsequent display (possibly after processing) on the Smart Device. For example, where the wireless receiver is a Sensor, the Sensor may be operative to translate the wireless energy into a two-dimensional array.
At step 2402, a pattern of digital values is generated based upon receipt of wireless energy into the wireless receiver. This pattern of digital values may be based on one or more qualities of the received wireless energy, including its intensity, spatial dispersion, wavelength, or angle of arrival. The pattern may be placed into an appropriate array. For example, if the display of the Smart Device is a two-dimensional display, then the pattern of digital values may comprise a two-dimensional representation of the image data received. In some embodiments, the pattern of digital values may be based on an aggregated set of values from an array of receivers. For example, if the basis of the digital values is the intensity of the wireless energy received into the receiver, then the digital value assigned to a given entry in the array may be based on a weighted average of intensity of wireless energy received at a plurality of the receivers in the array. Optionally, at step 2403, the wireless receiver may receive the wireless energy as an analog signal (for example, if the wireless receiver is a black-and-white sensor or an unfiltered CCD), and convert the analog signal to digital values through filtration or other analog-to-digital conversion. The set of digital values within the Radio Target Area is the Digital Radio Target Area.
With the Smart Device wireless receiver's Radio Target Area determined, the Smart Device's position should be determined as well, along with the positions of any items of interest in a given space. Collectively, the Smart Device and the item of interest may comprise wireless Nodes. Accordingly, at step 2404, coordinates representative of a wireless Node may be determined relative to a base Node. These coordinates may be determined in any appropriate coordinate system (such as Cartesian, polar, spherical polar, or cylindrical polar) and may be determined via RTLS or the orienteering-triangulation methods with various wavelengths or modalities, such as ultra-wideband, Bluetooth, etc. Additionally, the coordinates may be determined using an angle of arrival or angle of departure of a signal to or from the base Node, along with the distance from the base Node. By way of non-limiting example, this could produce a dataset that correlates the coordinates of three elements with the identities of those elements: {(0,0,0), BaseNode; (1,1,1), SmartDevice; (2,2,2), ItemOfInterest}. While this example may be used throughout the following discussion, it is understood to be non-limiting, as a given space may include a plurality of items of interest. Note that, in some embodiments, the Smart Device itself may become a dynamic database entry with a continuously (or periodically) updating set of coordinates. This may be useful in allowing a plurality of Smart Devices engaged with the system at the same time to interact with one another.
At step 2405, the position of the Base Node is determined relative to the defined physical area. In exemplary embodiments, this may include establishing the Base Node as an origin in the coordinate system and determining vectors from the Base Node to boundaries and items of interest (i.e., the distance from the Base Node and the direction from the Base Node to the boundaries and items of interest). In some examples, the Base Node may have an established reference relative to a global coordinate system established.
At step 2406, a Target Area is generated within a controller of the Smart Device. The Target Area may be the set of coordinates (relative to the Base Node) within the Radio Target Area of the wireless receiver. The Target Area may be limited by physical boundaries of the given space, such as walls, floors, ceilings, occlusions, etc. The Target Area may also be limited by distances that various types of signals may travel. For example, a sensor of audio signals may not be able to practically pickup signals over a background noise level that originate more than 1000 feet from a user position, purely as an example. In such a case, the Target Area for such signal types may be limited to that dimension.
At step 2407, respective positions of one or more wireless Nodes within the Target Area are determined. These positions may be determined relative to the physical Target Area or the Radio Target Area. The determination may be made with reference to the dataset discussed at step 2405, or it may be made dynamically based upon one or more Base Nodes and/or the Radio Target Area. Moreover, the determination may additionally be based on receipt of a wireless signal into the Smart Device from the wireless Node. This signal may indicate a position using the orienteering methods described herein.
At step 2408, a user interface may be generated on the Smart Device based upon the pattern of digital values generated at step 2402. The user interface may comprise a plurality of pixels, wherein each pixel comprises a visible color based upon the pattern of digital values generated at step 2402. For example, if the digital values were based upon receipt of visible light into the wireless receiver (e.g., a sensor), then the display may reflect a reasonably accurate color photograph of the Radio Target Area of the wireless receiver. If the digital values were based upon an intensity of received light from, for example, LIDAR, then the display may reflect a scan of the Radio Target Area. In some embodiments, the pixel may include an intensity of energy received into the receiver. In this way, aspects of the Radio Target Area characterized by an intensity of energy may be emphasized. For example, this may produce a LIDAR relief of an area or a heatmap of an area.
At step 2409, an icon may be generated in the user interface. Preferably the icon will be placed at a position relative to data quantifying received energy levels. In some embodiments, the icon location in a user interface will be indicative of a position of a Tag (Virtual or Physical). This position may be quantified via positional coordinates, such as Cartesian Coordinates, Polar Coordinates, Spherical Coordinates, and the like. The icon may be based upon an input from a user, stored data, quantified environmental conditions or other criteria related to an aspect of the Radio Target Area.
For example, an icon may indicate information about an Item of Interest located at a given set of coordinates within the Radio Target Area or Digital Radio Target Area. In another embodiment, the user may indicate on the display a position in which the user wishes to place an icon and add information about an Item of Interest (thus creating a new entry in the database, which may be populated with the coordinates of the indicated position). Moreover, the icon may change colors based upon the pattern of digital values. The icon may be overlaid on top of the display. The icon may resemble the letter “I,” a question mark, a thumbnail, or any other suitable image from a library. In some embodiments, the icon may change depending on one or more attributes of its corresponding database entry. For example, if the icon located at (4,4,4) relates to a restaurant menu, then the icon may resemble the letter “i” or a thumbnail of a menu. On the other hand, if this database entry is modified so that the corresponding database entry is a message, then the icon may update to a picture of an envelope.
In some embodiments, the icon-generation step may be based upon an inquiry to a database that uses the Digital Radio Target Area as an input. For example, upon generation of the Digital Radio Target Area, an associated set of coordinates in one or more dimensions may be generated. This may then be submitted to a database.
In some embodiments, an icon-generation step may be based upon an inquiry to a database that uses the user's position coordinates as an input. In these embodiments, both the Digital Radio Target Area based on an RTA as well as the universal Radio Target Area may be included in an inquiry submitted to the database.
In some examples, the user may have an option to limit or filter the types of database entries that may be queried for, such as in a non-limiting sense, the existence of real-world Tags, virtual Tags, sensor data values and streams from a particular class of sensors and the like.
Continuing with the example from step 2404, the Digital Radio Target Area may comprise the set of coordinates: ([1.5,10], [1.5,10], [1.5,10]). In this example, the database may return information about the Item Of Interest, but not about the Base Node. The Digital Radio Target Area may update when the Smart Device position changes, or by user input, the Digital Radio Target Area may remain static after a certain instance in time.
Continuing with
At step 2411, user-interactive functionality may be associated with the pixels comprising the icon. This may allow the user to “select” the icon by means of an input device (e.g., mouse, touchpad, keyboard), touchscreen, digital input, etc. Upon selection, the icon may be operative to interact with the user in one or more ways, including: displaying a message intended for the user (by text, audio, video, hologram, etc.); requesting credentials from the user to verify permissions (e.g., a password), displaying information about an item associated with the icon, prompting the user to update information about an item associated with the icon, etc. The user-interactive functionality may display static information (e.g., dimensions of the item), display dynamic information (e.g., an alarm state or sensor information relating to the item; for example, if the item is a refrigerator, internal temperature may be displayed), or produce a control panel that allows the user to issue control commands (e.g., remotely operating an automated apparatus by resetting an alarm state, taking remedial action based upon a sensor state as described herein, etc.) or to issue menu control commands such as to invoke a different user interface or screen of a user interface.
This may be useful in geospatial applications, or in procedurally generated activities. For example, a first user may generate a positional designation on a user interactive device, such as, for example an augmented-reality display to leave a narrative, icon or other input associated with the first use. Additionally, the same or another user may log positional coordinates and upload an image that could be displayed submitting a database query including those coordinates. Entry of the coordinates and essential credentials may provide access to the content associated with the positional coordinates.
At step 2412, the preceding steps may be integrated by generating a display comprising the user interface, the icon, and at least some of the associated user-interactive functionality. In embodiments, in which a plurality of Smart Devices are themselves part of the database, this may allow various users to send messages, images, etc. to each other.
At step 2413, detection of movement of the Smart device may cause a branch back to step 2405. Based upon that movement of the Smart Device, a defined physical area from which wireless energy is received (i.e., the Radio Target Area based upon the Target Area) may be changed. The movement may be detected using input from wireless communications, magnetic field sensors, an accelerometer, feature-recognition software, or other similar apparatus and algorithms. In other examples, the position of the Smart Device may be dynamically obtained using any of the techniques of position determination, such as triangulation with reference nodes. Here, too, a change of position detected in this manner may cause a branch back to step 2405. The Target Area may be based upon the position of the Base Node, the relative positions of the wireless Nodes, and the Smart Device.
Referring to
In some examples, the user may be prompted to choose a desired coordinate system for the display at step 2503. In other examples, a user interface of the system may have a setpoint function which the user may invoke to gain access to user settable parameters which may include they type of coordinate system to use, such as for example Cartesian or spherical coordinates.
In still further examples, the system may decide to default to a particular coordinate system depending on the nature of the type of data its positional reference devices may be obtaining or providing.
At step 2504, if the coordinate system was chosen as Cartesian coordinates, the system may utilize triangulation amongst multiple reference point transceivers. Alternatively, if the coordinate system was chosen as polar coordinates, at step 2505, the system may be operative to execute software and reference positioning devices that utilize angles and distances involved in transceiving and location.
In either case, at step 2506, the position of a Sensor attached to the smart device of the user may be determined. In some examples, the system may have multiple and redundant location system. A combination of such position determinations may result in superior accuracy of an aggregated position result. Accordingly, at optional step 2507, a wireless position determination may be performed with the smart device to establish a verification of the position of the Smart Device and the Sensor attached. Referring now to step 2508, a direction that the sensor is facing in may be determined. Although there may be a number of different manners of determining orientation as have been described herein, in an example, the orientation may be determined based upon wireless transmission and/or wireless verification.
Referring now to step 2509, an energy-receiving Sensor included in the Smart Device or in logical communication with the Smart Device may be used to quantify energy levels perceivable at the position and in the direction of the Smart Device. The resulting quantification may depend on aspects of the Sensor device, but the resulting data will quantify a characteristic for the RTA.
In some embodiments, an optional step 2510 may be performed by an element of the system such as the smart device or a server in communication with the Smart Device. The element of the system may compare one or more of position information, orientation information and the image data itself to calculate an estimate of whether the RTA angle has changed for the sensing element.
In general, at step 2511, the RTA of the Sensor device used to capture the image in step 1209 may be quantified. In an optional step 2512, coordinates relating to the instant RTA of the image may be established. In some examples, this may relate to a range of three-dimensional coordinates that are addressed by the RTA of the Sensor element. In general, at step 2513, the system may look up, or in some cases generate, location coordinates for Tags that are determined to be within the quantified RTA. In some database systems that the system may have access to, real-world or virtual-world tags may be tracked in a coordinate system with a certain origin.
If the current origin established at step 2501 is offset from a particular database related origin, then one or both the coordinate system values may be converted to each other to align their respective origins. At step 2514, the Tags in an aligned coordinate system may have their positions compared to the current RTA and a selection for the set of Tags that are within the RTA may be made.
In some alternative examples, a display of all Tags that are authorized for access to the user regardless of whether they are in the RTA may be made using associated aligned coordinates as discussed in reference to step 2513.
Referring now to step 2515, in an example, the Smart Device of the user may be used to generate and display a user interface to the user based upon the captured image and the associated tag icons within the RTA. These associated Tag icons may have at least the hardware and be operative to perform the functionality as has been discussed herein.

Embodiments may also include routing particular antenna/antenna array outputs to the BLE5.1-consistent Node 2610 in a controlled and timed sequence. A processing Module 2670 may coordinate a connection of the Node 2650 to external peripherals.
In some examples, circuitry 2680 to logically communicate with one or more of: a Peripheral, a data Connection, Cameras and Sensors controllers, and components to perform data and image acquisition of various kinds, or it may interface external components with the Node 2650.
The Node 2650 may also include its own power management unit 2660 which may take connected power or battery power or both and use it to prove the various power needs of the components of the assembly. The Node 2650 may have its own processing modules 2670 or collections of different types of processing functions which may have dedicated memory components 2671. In some examples, specialized processing chips of various kinds such as Graphical Processing Units and fast mathematics function calculators as well as dedicated artificial intelligence processing chips may be included to allow the Node 2650 to perform various computational functions including location determination of wirelessly connected devices amongst other functions. There may be numerous other functions to include in a Node 2650 and alternative types of devices to perform the functions presented herein.
In some examples as illustrated in
A directional antenna may include, for example, an antenna with RF shielding over some portion of an antenna's circumference. For example, 270° (or some other subset of a 360° circumference of an antenna), or an antenna array may have RF shielding to block and/or reflect back an RF signal towards the antenna-receiving portion. Other directional antennas may include a shield blocking less than 360° of RF transmissions that rotates around a receiving portion of an antenna and only receives RF communications from a direction of an opening in the shield. Shielded antennas may provide improved determination of a direction from which a wireless transmission is being received from, since RF noise is blocked from a significant portion of a reception sphere.

A microphone 2710 and associated circuitry may convert the sound of the environment, including spoken words, into machine-compatible signals. Input facilities may exist in the form of buttons, scroll wheels, or other tactile Sensors such as touch-pads. In some embodiments, input facilities may include a touchscreen display.
Visual feedback to the user is possible through a visual display, touchscreen display, or indicator lights. Audible feedback 2734 may come from a loudspeaker or other audio transducer. Tactile feedback may come from a vibrate module 2736.
A magnetic force sensor 2737 such as a Hall Effect Sensor, solid state device, MEMS device or other silicon based or micro-electronic apparatus.
A motion Sensor 2738 and associated circuitry converts motion of the smart device 2702 into a digital value or other machine-compatible signals. The motion Sensor 2738 may comprise an accelerometer that may be used to sense measurable physical acceleration, orientation, vibration, and other movements. In some embodiments, motion Sensor 2738 may include a gyroscope or other device to sense different motions.
A location Sensor 2740 and associated circuitry may be used to determine the location of the device. The location Sensor 2740 may detect Global Position System (GPS) radio signals from satellites or may also use assisted GPS where the mobile device may use a cellular network to decrease the time necessary to determine location. In some embodiments, the location Sensor 2740 may use radio waves to determine the distance from known radio sources such as cellular towers to determine the location of the smart device 2702. In some embodiments these radio signals may be used in addition to GPS.
Smart Device 2702 comprises logic 2726 to interact with the various other components, possibly processing the received signals into different formats and/or interpretations. Logic 2726 may be operable to read and write data and program instructions stored in associated storage or memory 2730 such as RAM, ROM, flash, SSD, or other suitable memory. It may read a time signal from the clock unit 2728. In some embodiments, Smart Device 2702 may have an on-board power supply 2732. In other embodiments, Smart Device 2702 may be powered from a tethered connection to another device or power source.
Smart Device 2702 also includes a network interface 2716 to communicate data to a network and/or an associated computing device. Network interface 2716 may provide two-way data communication. For example, network interface 2716 may operate according to the internet protocol. As another example, network interface 2716 may be a local area network (LAN) card allowing a data communication connection to a compatible LAN. As another example, network interface 2716 may be a cellular antenna and associated circuitry which may allow the mobile device to communicate over standard wireless data communication networks. In some implementations, network interface 2716 may include a Universal Serial Bus (USB) to supply power or transmit data. In some embodiments, other wireless links may also be implemented.
As an example of one use of Smart Device 2702, a reader may scan some coded information from a location marker in a facility with Smart Device 2702. The coded information may include for example, a hash code, bar code, RFID, or other data storage device. In some embodiments, the scan may include a bit-mapped image via the optical capture device 2708. Logic 2726 causes the bit-mapped image to be stored in memory 2730 with an associated time-stamp read from the clock unit 2728. Logic 2726 may also perform optical character recognition (OCR) or other post-scan processing on the bit-mapped image to convert it to text. Logic 2726 may optionally extract a signature from the image, for example by performing a convolution-like process to locate repeating occurrences of characters, symbols, or objects, and determine the distance or number of other characters, symbols, or objects between these repeated elements. The reader may then upload the bit-mapped image (or text or other signature if post-scan processing has been performed by logic 2726) to an associated computer via network interface 2716.
As an example of another use of Smart Device 2702, a reader may recite words to create an audio file by using microphone 2710 as an acoustic capture port. Logic 2726 causes audio file to be stored in memory 2730. Logic 2726 may also perform voice recognition or other post-scan processing on the audio file to convert it to text. As above, the reader may then upload the audio file (or text produced by post-scan processing performed by logic 2726) to an associated computer via network interface 2716.
A directional sensor 2741 may also be incorporated into Smart Device 2702. The directional device may be a compass and be based upon a magnetic reading or based upon network settings. The magnetic sensor may include three axes of magnetic sensitive elements and may also be coupled with an accelerometer in the directional sensor 2741.
A LiDAR sensing system 2751 may also be incorporated into Smart Device 2702. The LiDAR system may include a scannable laser light (or other collimated) light source which may operate at nonvisible wavelengths such as in the infrared. An associated sensor device, sensitive to the light of emission may be included in the system to record time and strength of returned signal that is reflected off of surfaces in the environment of Smart Device 2702. Aspects relating to capturing data with LiDAR and comparing it to a library of stored data (which may be obtained at multiple angles to improve accuracy) are discussed above.
Physical world and virtual-world based imagery related to the environment of a user may be presented via a user interface that may display on a Smart Device screen or other interactive mechanism, or in some embodiments, be presented in an augmented of virtual environment, such as via a VR or AR headset. The imagery displayed upon these devices may represent a composite of image data reflective of a real-world data stream as well as digitally added/superimposed image data from a virtual or digital source data stream. A user may be presented a typical image as it would look to the user's eyes physically, upon which digital shapes representing virtual “Tags” may be superimposed to represent the presence of digital information that may be accessed by a user. In other examples, the digital information may be directly displayed as a superposition. In some examples, the real-world and virtual-world environments may be displayed separately on a screen or separately in time.
In some examples, the “physical world image” may also be digitally formed or altered. For, example, an imaging device may obtain images where the sensing elements of the imaging device are sensitive to a different frequency of electromagnetic radiation, such as in a non-limiting sense infrared radiation. The associated “real-world image” may be a color scale representation of the images obtained in the infrared spectrum. In still further examples, two different real-world images may be superimposed upon each other with or without additional virtual elements. Thus, a sensor image may have an IR sensor image superimposed over part or all of the image and a digital shape representing a virtual Tag may be superimposed.
In some implementations, a virtual reality headset may be worn by a user to provide an immersive experience from a vantage point such that the user may experience a virtual representation of what it would be like to be located at the vantage point within an environment at a specified point in time. The virtual representation may include a combination of simulated imagery, textual data, animations and the like and may be based on scans, image acquisition and other Sensor inputs, as examples. A virtual representation may therefore include a virtual representation of image data via the visual light spectrum, image data representing image scans obtained via infrared light spectrum, noise, and vibration reenactment. Although some specific types of exemplary sensor data have been described, the descriptions are not meant to be limiting unless specifically claimed as a limitation and it is within the scope of this disclosure to include a virtual representation based upon other types of captured sensor data may also be included in the AVM virtual reality representation.
It should be noted that although a Smart Device is generally operated by a human Agent, some embodiments of the present disclosure include a controller, accelerometer, data storage medium, Image Capture Device, such as a CCD capture device and/or an infrared capture device being available in an Agent that is an unmanned vehicle, including for example an unmanned ground vehicle (“UGV”) such as a unit with wheels or tracks for mobility and a radio control unit for communication. or an unmanned aerial vehicle (“UAV”) or other automation.
In some embodiments, multiple unmanned vehicles may capture data in a synchronized fashion to add depth to the image capture and/or a three-dimensional and four-dimensional (over time) aspect to the captured data. In some implementations, UAV position may be contained within a perimeter and the perimeter may have multiple reference points to help each UAV (or other unmanned vehicle) determine a position in relation to static features of a building within which it is operating and also in relation to other unmanned vehicles. Still other aspects include unmanned vehicles that may not only capture data, but also function to perform a task, such as paint a wall, drill a hole, cut along a defined path, or other function. As stated throughout this disclosure, the captured data may be incorporated into a virtual model of a space or Structure.

A/R interfaces according to the present invention thereby create a reciprocal relationship of a user or other Agent with its environment, including a real time view of the physical world that is augmented with the power of the cyber world. The power of the cyber world may include one or more of: IoT sensing capabilities that far exceed those of human sensory capabilities; location specific data (or other digital content) storage; location specific data (or other digital content) access; location tracking of Agents and/or equipment items; condition tracking of Agents, structures, or equipment items; location specific ecommerce; and almost any functionality available via a distributed network. Such as the Internet.
Additional non-limiting exemplary aspects of an A/R interface according to the present invention include one or more of: an interactive portion indicating RTLS coordinates of a Tag 2804; RTLS coordinates of an image capture device, such as a CCD camera 2805; bearings of the image capture device (or other environment mapping device, such a laser device, a sonic device etc.) 2806; and calibration controls 2807.

According to the present invention, an additional layer of security may be provided by requiring that a user 2824 or other Agent requesting access to digital content accessible via the Virtual Tags (represented by icon 2801) and Physical Tags (represented by icons 2802-2803) must be in a qualified area to access the Tags. An accessible area may include an area from which the icons 2801-2803 associated with the respective Tags may be viewed, or another physical area designated as a qualified access area.

A qualified access area may include, by way of non-limiting example, an area around a workstation in an office, an area within a structure (such as an office building, manufacturing facility, distribution warehouse, consulate etc.); an area proximate to or within an infrastructure item (such as a bridge; tunnel; power station; cell tower, etc.); a home office area; on a ship; or other quantifiable area that has been designated as authorized to access designated digital content. The designated digital content may or may not be associated with a Virtual Tag, Physical Tag and/or an icon in an A/R or VR interface.
Although
In some embodiments, remote or on site interaction may include, for example, monitoring digital content that is deposited into a Virtual Tag and/or retrieved from a Virtual Tag, and/or deleted from a Virtual Tag.
For example, by way of illustration, an administrator may be able to view cyber activity associated with a remote worker by monitoring work product generated by the remote worker in an authorized remote work area. The remote worker may have an onsite work area within a virtual fence around a company facility and another authorized work area designated as a home office. The two areas may be the only areas from which the worker is able to access protected digital content. A respective Virtual Tag may be associated with each of the onsite work area and the at homework area and work product produced by the worker will be deposited into an appropriate Virtual Tag based upon where the worker is located while working during a specified time period. Virtual Tags may be protected in that they are only visible to the worker and to the worker's administrator.
In this example, an unauthorized person would need to know normal login credentials, and have a Node associated with the worker (the node may be a smart device, employee badge, dongle etc.); and also know what areas are authorized for access to specified digital content and also be at an authorized area, in order to gain access to protected digital content.
Location coordinates may also make up a portion of an enhanced PKI key. In such embodiments, instead of simply having a private key, the private key portion is replaced by a value generated via location coordinates; or a range of values for location coordinates of an Agent position. Still other embodiments include a private key comprising a value generated by an algorithm that processes location coordinates for one or both of: location coordinates at a time of request of access to digital content; and a series of values for locations coordinates associated with the user at specified time periods (or instances) prior to the request for access to the digital content. For example, if the user generates location coordinates indicating that they are in their office during a particular hour of the day, and a request for access to protected digital data is received with coordinates indicating that the user is at an authorized home office at the same hour of the day, the VTI may deny access to the digital content until the conflict is resolved. Such embodiments may include a private key portion that is not known to the user and is generated by a smart device or other Node designating the user's position.

In another aspect of the present invention, a user may retrieve digital content based upon knowledge of where an icon associated with storage of the digital content is located. Users sometimes have difficulty remembering which file folder, or disk drive, or other file storage mechanism holds particular content, however, humans often associate particular knowledge with a particular location which may aid in remembering where to retrieve information.
For example, a family or business may have a “digital safe” 3007 located at a particular position within the home, or office. The digital safe 3007 will in essence be a Virtual Tag. The digital safe 3007 may contain sensitive documents, passwords, photos, videos, or other personal items that are important and private to the family members. The digital safe 3007 may be configured so that it is only accessible from within specified areas, e.g., an area 3005 included in an office or in a house corresponding to the location coordinates of the digital safe 3007 that is designated as an area of digital content interaction. In some embodiments, a physical hard drive, SSD or other storage device for the device may be located on site of the home, or remotely, such as in the cloud. If on site, the storage device need not be accessible from any location outside of the home (or other designated location). Access to the digital safe may require an authorized user, with an authorized device, making an access request from an authorized location (location coordinates or area of coordinates), as well as knowledge of the existence of the digital safe (Virtual Tag) which is essentially invisible to unauthorized users.
