The demand for simulated environment technology such as virtual reality (VR) devices and systems has been increasing in recent years. VR may refer to computer technologies that generate realistic images, sounds and other sensations to create an environment. The environment may be three dimensional and immersive and may simulate a user's physical presence in this environment. A user may be enabled to interact with the virtual space and objects in the environment using display screens or projectors and other devices. VR devices provide a unique user experience and may be used in any number of settings such as a user's living room or bedroom or in a public setting. Haptic simulations may be employed to physically create sensations on a user's body that simulate events that occur in the virtual reality environment.
Features and advantages of the disclosure will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the disclosure; and, wherein:
Before technology embodiments are described, it is to be understood that this disclosure is not limited to the particular structures, process steps, or materials disclosed herein, but is extended to equivalents thereof as would be recognized by those ordinarily skilled in the relevant arts. It should also be understood that terminology employed herein is used for describing particular examples or embodiments only and is not intended to be limiting. The same reference numerals in different drawings represent the same element. Numbers provided in flow charts and processes are provided for clarity in illustrating steps and operations and do not necessarily indicate a particular order or sequence.
Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of layouts, distances, network examples, etc., to convey a thorough understanding of various technology embodiments. One skilled in the relevant art will recognize, however, that such detailed embodiments do not limit the overall technology concepts articulated herein, but are merely representative thereof.
As used in this written description, the singular forms “a,” “an” and “the” include express support for plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an integrated circuit” includes a plurality of such integrated circuits.
Reference throughout this specification to “an example” means that a particular feature, structure, or characteristic described in connection with the example is included in at least one technology embodiment. Thus, appearances of the phrases “in an example” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment.
As used herein, a plurality of items, structural elements, compositional elements, and/or materials can be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. In addition, various technology embodiments and examples can be referred to herein along with alternatives for the various components thereof. It is understood that such embodiments, examples, and alternatives are not to be construed as de facto equivalents of one another, but are to be considered as separate and autonomous representations under the present disclosure.
Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of layouts, distances, network examples, etc., to provide a thorough understanding of technolgoy embodiments. One skilled in the relevant art will recognize, however, that the technology can be practiced without one or more of the specific details, or with other methods, components, layouts, etc. In other instances, well-known structures, materials, or operations may not be shown or described in detail to avoid obscuring aspects of the disclosure.
In this disclosure, “comprises,” “comprising,” “containing” and “having” and the like can have the meaning ascribed to them in U.S. Patent law and can mean “includes,” “including,” and the like, and are generally interpreted to be open ended terms. The terms “consisting of” or “consists of” are closed terms, and include only the components, structures, steps, or the like specifically listed in conjunction with such terms, as well as that which is in accordance with U.S. Patent law. “Consisting essentially of” or “consists essentially of” have the meaning generally ascribed to them by U.S. Patent law. In particular, such terms are generally closed terms, with the exception of allowing inclusion of additional items, materials, components, steps, or elements, that do not materially affect the basic and novel characteristics or function of the item(s) used in connection therewith. For example, trace elements present in a composition, but not affecting the composition's nature or characteristics would be permissible if present under the “consisting essentially of” language, even though not expressly recited in a list of items following such terminology. When using an open ended term in this written description, like “comprising” or “including,” it is understood that direct support should be afforded also to “consisting essentially of” language as well as “consisting of” language as if stated explicitly and vice versa.
The terms “first,” “second,” “third,” “fourth,” and the like in the description and in the claims, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that any terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Similarly, if a method is described herein as comprising a series of steps, the order of such steps as presented herein is not necessarily the only order in which such steps may be performed, and certain of the stated steps may possibly be omitted and/or certain other steps not described herein may possibly be added to the method.
The terms “left,” “right,” “front,” “back,” “top,” “bottom,” “over,” “under,” and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in other orientations than those illustrated or otherwise described herein.
The term “coupled,” as used herein, is defined as directly or indirectly connected in an electrical or nonelectrical manner. “Directly coupled” objects or elements are in physical contact with one another. In this written description, recitation of “coupled” provides express support for “directly coupled” and vice versa. Objects described herein as being “adjacent to” each other may be in physical contact with each other, in close proximity to each other, or in the same general region or area as each other, as appropriate for the context in which the phrase is used. Occurrences of the phrase “in one embodiment,” or “in one aspect,” herein do not necessarily all refer to the same embodiment or aspect.
As used herein, comparative terms such as “increased,” “decreased,” “better,” “worse,” “higher,” “lower,” “enhanced,” “maximized,” minimized,” and the like refer to a property of a device, component, or activity that is measurably different from other devices, components, or activities in a surrounding or adjacent area, in a single device or in multiple comparable devices, in a group or class, in multiple groups or classes, or as compared to the known state of the art. For example, a data region that has an “increased” risk of corruption can refer to a region of a memory device, which is more likely to have write errors to it than other regions in the same memory device. A number of factors can cause such increased risk, including location, fabrication process, number of program pulses applied to the region, etc.
As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases, depend on the specific context. However, generally speaking, the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. For example, a composition that is “substantially free of” particles would either completely lack particles, or so nearly completely lack particles that the effect would be the same as if it completely lacked particles. In other words, a composition that is “substantially free of” an ingredient or element may still actually contain such item as long as there is no measurable effect thereof.
As used herein, the term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint. However, it is to be understood that even when the term “about” is used in the present specification in connection with a specific numerical value, that support for the exact numerical value recited apart from the “about” terminology is also provided.
Numerical amounts and data may be expressed or presented herein in a range format. It is to be understood, that such a range format is used merely for convenience and brevity, and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to about 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3, and 4 and sub-ranges such as from 1-3, from 2-4, and from 3-5, etc., as well as 1, 1.5, 2, 2.3, 3, 3.8, 4, 4.6, 5, and 5.1 individually.
This same principle applies to ranges reciting only one numerical value as a minimum or a maximum. Furthermore, such an interpretation should apply regardless of the breadth of the range or the characteristics being described.
As used herein, the term “circuitry” can refer to, be part of, or include an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), and/or memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable hardware components that provide the described functionality. In some aspects, the circuitry can be implemented in, or functions associated with the circuitry can be implemented by, one or more software or firmware modules. In some aspects, circuitry can include logic, at least partially operable in hardware.
Various techniques, or certain aspects or portions thereof, may take the form of program code (i.e., instructions) embodied in tangible media, such as floppy diskettes, compact disc-read-only memory (CD-ROMs), hard drives, transitory or non-transitory computer readable storage medium, or any other machine-readable storage medium wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the various techniques. Circuitry can include hardware, firmware, program code, executable code, computer instructions, and/or software. A non-transitory computer readable storage medium can be a computer readable storage medium that does not include signal. In the case of program code execution on programmable computers, the computing device may include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. The volatile and non-volatile memory and/or storage elements may be a random-access memory (RAM), erasable programmable read only memory (EPROM), flash drive, optical drive, magnetic hard drive, solid state drive, or other medium for storing electronic data. The node and wireless device may also include a transceiver module (i.e., transceiver), a counter module (i.e., counter), a processing module (i.e., processor), and/or a clock module (i.e., clock) or timer module (i.e., timer). One or more programs that may implement or utilize the various techniques described herein may use an application programming interface (API), reusable controls, and the like. Such programs may be implemented in a high level procedural or object oriented programming language to communicate with a computer system. However, the program(s) may be implemented in assembly or machine language, if desired. In any case, the language may be a compiled or interpreted language, and combined with hardware implementations.
As used herein, the term “processor” can include general purpose processors, specialized processors such as VLSI, FPGAs, or other types of specialized processors, as well as base band processors used in transceivers to send, receive, and process wireless communications.
It should be understood that many of the functional units described in this specification may have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom very-large-scale integration (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions, which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module may not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network. The modules may be passive or active, including agents operable to perform desired functions.
Reference throughout this specification to “an example” or “exemplary” means that a particular feature, structure, or characteristic described in connection with the example is included in at least one embodiment of the present technology. Thus, appearances of the phrases “in an example” or the word “exemplary” in various places throughout this specification are not necessarily all referring to the same embodiment.
Example Embodiments
An initial overview of technology embodiments is provided below and then specific technology embodiments are described in further detail later. This initial summary is intended to aid readers in understanding the technology more quickly but is not intended to identify key features or essential features of the technology nor is it intended to limit the scope of the claimed subject matter.
Simulated environments seek to provide a user with an immersive experience that may simulate experience from the real world or provide a fictional experience from a fantasy world. Simulated environments may be virtual reality, augmented realty, or mixed reality. Software may be used to create the simulated environment. Hardware and other technologies are employed to provide feedback or stimuli to a user's senses. For example, a haptic actuator may be employed to provide mechanical feedback to a user. A haptic actuator may be referred to as a device used for haptic or kinesthetic communication that recreates the sense of touch by applying forces, vibrations, or motions to the user. This mechanical stimulation can be used to assist in the creation of virtual objects in a computer simulation, to control such virtual objects, and to enhance the remote control of machines and devices. Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. Other hardware devices used for simulated environments may include a head-mounted display (HMD), such as a wearable object that a user wears on the head and over the eyes. The HMD may have a screen that displays images to the user. Headphones or other speakers may also be employed to provide audio feedback to the user.
To provide accurate haptic feedback to the user, the haptic actuator is placed in the appropriate location on the user's body. In one solution, a haptic actuator is incorporated into a wearable article such as a glove or suit that is worn by the user. The location of the haptic actuator on the wearable article may be communicated to or known by the software controlling the simulated environment. However, a haptic actuator with a fixed location on/in the wearable article limits the haptic feedback that can be provided to the user. Therefore, a haptic actuator with a fixed location may turn out to be useful for one simulated environment, but not a second simulated environment. The present technology provides a movable haptic actuator that can be placed in more than one location on a wearable article.
When moving the movable haptic actuator from one location to another, it is possible that the haptic actuator may be moved to a location on the wearable article that is not known to the simulated environment software. If the location is not known to the simulated environment software then the haptic actuator may not be useful in providing feedback to the user. The present technology provides techniques for locating the position of the movable haptic actuator on the wearable article after the movable haptic actuator has been attached or moved onto the wearable article. For example, in some embodiments, the movable haptic actuator may have a fastener that is employed to attach or couple the movable haptic actuator to the wearable article. In one embodiment, the fastener may be reusable and comprise components such as a hook and loop fastener (e.g. Velcro), snap, button, magnets, have a size that allows it to fit into a pocket, etc. or the fastener may have a one-time use such as an adhesive (e.g. an adhesive backing film) that is replaced each time the movable haptic actuator is moved.
In one aspect, the wearable article is capable of auto detecting a location of the haptic actuator on the wearable article. For example, the wearable article may comprise or comprise a conductive fabric having a matrix of addressable locations configured to indicate a presence or absence of a haptic actuator. A controller associated with the wearable article may be configured to determine a presence or absence of the haptic actuator and thus identify a location or the position of the haptic actuator on the wearable article. The location may then be communicated to the simulated environment software such that the simulated environment software may provide information to the controller for the haptic actuator to provide feedback to the user during the simulated environment experience. In some embodiments, the wearable article may be a haptic suit that is a full body suit. The wearable article may also refer to one or more of the following: gloves, vests, shirts, pants, shorts, socks, hats, hoods, arm bands, sleeves, leggings, shoes, headbands, face masks, etc.
In one embodiment, the conductive fabric of the wearable article may form rows and columns of addressable cells on the wearable article. The conductive fabric may also include leads that electrically connect to a portion of the haptic actuator. The leads combined with the addressable cells of the wearable article are employed by the controller to detect the location of the haptic actuator.
In one aspect, a sensor external to the user, the wearable article and the haptic actuator is employed to detect a location of the haptic actuator on the wearable article. For example, the sensor may be mounted to a structure such as a wall and is able to detect a wearable article and the haptic actuator within range of the sensor. The sensor may be an optical device such as digital camera or a photodiode. Once a haptic actuator is mounted or attached to the wearable article, the sensor may then operate to detect the location. In one aspect, the haptic actuator may include an emitter that emits a signal to be detected by the sensor. For example the emitter may be a light source such as an infrared light source or a laser. The sensor and emitter may employ LiDAR, or other optical technology, to determine the location of the haptic actuator. By using a sensor to determine a location of the haptic actuator, the wearable article may not employ conductive fabric. However, a wearable article with conductive fabric may also use a haptic actuator with an emitter and an external sensor to determine the location of the haptic actuator.
The haptic actuator 102 may include a communications component 106. The communications component 106 may be used by the haptic actuator 102 to communicate with a controller such as a microcontroller. The controller may be used in conjunction with a wearable article to determine the location of the haptic actuator 102 on the wearable article. The controller may also provide information from the simulated environment software to direct the haptic actuator 102 to activate and provide feedback to a user employing the haptic actuator 102. The communications component 106 may be wired to the controller or may be wireless. The communications component 106 may use communications protocols to communicate with the controller such as Bluetooth, ZigBee, or other wireless protocols.
The communications component 106 may include a feedback motor 108. The feedback motor 108 may be referred to as a haptics motor and driver and operates to provide sensation to the user employing the haptic actuator 102. For example, the feedback motor 108 may vibrate or create other tactile sensations. The haptic actuator 102 including the communications component 106 and the feedback motor 108 may be powered via a power source. A haptic actuator may have a power source that only serves one haptic actuator. Alternatively, a single power source may power multiple haptic actuators associated with the same wearable article.
In one aspect, the wearable article 202 is capable of housing or having the haptic actuator 208 attached to any location on the wearable article 202. The haptic actuator 208 may have all or some of the capabilities and features described for the haptic actuator 102 of
The wearable article 202 may include a controller 204. The controller 204 may communicate with the haptic actuator 208. The controller 204 may receive information from the simulated environment software. The information may be sent to the haptic actuator 208 as commands for the haptic actuator 208 to provide feedback to the user wearing the wearable article 202. The controller 204 may be capable of communicating with a plurality of haptic actuators. The controller may communicate wireless or use wired connected to communicate with the haptic actuator 208. For wireless communications, the controller 204 may employ a transmitter and receiver that use wireless protocols such as Bluetooth or ZigBee. For wired communications, a plurality of haptic actuators may be daisy chained together to communicate with the controller 204. The wearable article 202 may include a power source 206. The power source 206 may be a battery or other mobile power source. The battery may be rechargeable or a one-time use power source. The power source 206 may power a plurality of haptic actuators or one haptic actuator. The power source may be wired to an external power source such as a traditional electrical wall outlet.
In one aspect, the simulated environment software may direct a user where to place the haptic actuator 208 on the wearable article 202. For example, the simulated environment software may direct the user to fasten the haptic actuator 208 to the right side of the abdomen of the wearable article 202. The simulated environment software may generate objects (e.g. physics objects) in the simulated environment designed to interface with a particular location of the user's body. The directed location will allow the haptic actuator 208 to provide feedback from the simulated environment software to the user based on the location of the physics objects in the simulated environment. After the haptic actuator 208 has been fastened to the right side of the abdomen, the techniques of the present technology may be employed to detect the actual location of the haptic actuator 208. If the haptic actuator 208 is located at the proper location directed by the simulated environment software, the simulated environment may begin operations. The simulated environment software may also determine that the haptic actuator 208 is not in the proper directed location. The simulated environment software may then provide further directions to the user to modify or move the location of the haptic actuator 208 on the wearable article 202.
The actuator 406 and the actuator 408 may have all the same features and capabilities of the haptic actuator 102 of
The wires 418, 420, 422, 424, and 426 may carry an electric current from a power source 410. The power source 410 may be attached or coupled to the conductive fabric 402 or may be separate from the conductive fabric 402. The power source 410 may be a battery or other power source. The power source 410 may be used to power the actuator 406 and the actuator 408. However, a separate power source may be used to power the haptic actuators fastened to the conductive fabric 402. The power source 410 may supply current and voltage to the wires 418, 420, 422, 424, and 426. In one aspect, the current may be a few micro amperes. The actuator 406 is depicted as being in contact with the wire 418 and the wire 426. The actuator 408 is depicted as be in contact with the wire 422 and the wire 424. An actuator that is in contact with one of the wires 418, 420, 422, 424, and 426 will change the voltage, current, and/or resistance in the particular wire. Sensors associated with the power source 410 or the controller 404 may then detect the presence or absence of a haptic actuator. In one aspect, the actuator 406 or the actuator 408 detect their location on the conductive fabric 402 and communicate that information to the controller 404. The controller 404 may map each address of the cells of the conductive fabric 402 and thus once an address of a haptic actuator is known, the location of the haptic actuator on the wearable article may be known. This information may be communicated to the simulated environment software. The simulated environment software may then use this information to provide commands to the haptic actuator to provide feedback to the user employing the wearable article and the haptic actuators where the feedback is based on what is occurring in the simulated environment. For example, the simulated environment may create physics objects in the simulated environment that correspond with the location of the haptic actuator fastened to the wearable article.
The haptic actuator 504 may be coupled to, or otherwise associated with, an emitter 506. The emitter 506 may emit or generate a signal for the sensor 508 to recognize. For example, the emitter 506 may be a light source including an infrared light source or a laser. The sensor 508 and the emitter 506 together may employ techniques such as LiDAR to identify a position of the haptic actuator 504. The position of the haptic actuator 504 may be determined in virtual space in the simulated environment software and mapped to positions on the user's body. In one aspect, the sensor 508 may identify the location of the haptic actuator 504 by any outside-in mechanism with respect to a fixed reference. In one aspect, the emitter 506 is emitting light that a camera of sensor 508 can detect and the location of the haptic actuator 504 on the wearable article 502 is detected or tracked by the camera connected to host system and an accurate depth and position of the haptic actuator 504 is created using a body model of the user with the wearable article 502.
The sensor 508 may be mounted on a structure 510. For example, the structure 510 may be a wall or a pole. The sensor 508 may have a range for operations. Therefore the user of the wearable article 502 may stand within range of the sensor 508 while the sensor 508 is detecting the location of the haptic actuator 504. The sensor 508 may be capable of detecting a plurality of haptic actuators fastened to the wearable article 502.
During the use of the wearable article 502 with the haptic actuator 504 for a simulated environment, the haptic actuator 504 may be moved on the wearable article 502 or another haptic actuator may be fastened to the wearable article 502. The sensor 508 may be capable of detecting the move of the haptic actuator 504 to a second location on the wearable article 502 and may be capable of detecting the additional haptic actuator fastened to the wearable article 502. The sensor 508 may be configured to operate at predetermined intervals. For example, the sensor 508 may perform operations to detect the location of potential haptic actuator every five seconds or at any other interval. Alternatively, the sensor 508 may continually operate during a simulated environment session such that the location of the haptic actuator 504 may be continually updated in real time. This may be described as automatically tracking a location of the haptic actuator 504. The sensor 508 may be used in conjunction with a computer system to identify and determine the location of the haptic actuator 504 on the wearable article 502. The computer system may incorporate the sensor 508 or may be located remotely from the sensor 508.
Once the position or location of the haptic actuator 504 has been identified on the wearable article 502, information pertaining to the position of the haptic actuator 504 may be sent to a controller associated with the wearable article 502 and the simulated environment software. The simulated environment software may be executing on a computer system separate from the wearable article 502 and the sensor 508. The simulated environment software may map the location of the haptic actuator 504 on the user's body and then provide information to the haptic actuator 504 via the control such that the haptic actuator 504 provides feedback in the form of physical sensations during the simulated environment operations.
The system can also include an I/O (input/output) interface 710 for controlling the I/O functions of the system, as well as for I/O connectivity to devices outside of the system. A network interface can also be included for network connectivity, either as a separate interface or as part of the I/O interface 710. The network interface can control network communications both within the system and outside of the system. The network interface can include a wired interface, a wireless interface, a Bluetooth interface, optical interface, and the like, including appropriate combinations thereof. Furthermore, the system can additionally include various user interfaces, display devices, as well as various other components that would be beneficial for such a system.
The system can also include memory in addition to memory 704 that can include any device, combination of devices, circuitry, and the like that is capable of storing, accessing, organizing and/or retrieving data. Non-limiting examples include SANs (Storage Area Network), cloud storage networks, volatile or non-volatile RAM, phase change memory, optical media, hard-drive type media, and the like, including combinations thereof.
The processor 706 can be a single or multiple processors, and the memory 704 can be a single or multiple memories. The local communication interface can be used as a pathway to facilitate communication between any of a single processor, multiple processors, a single memory, multiple memories, the various interfaces, and the like, in any useful combination.
The system can also include a networking interface 712, and a user interface 714 for interacting with the user. The system can also include a display screen 716 for displaying images and the user interface 714 (e.g. a graphical user interface).
The disclosed embodiments may be implemented, in some cases, in hardware, firmware, software, or any combination thereof. Portions of the disclosed embodiments may also be implemented as instructions carried by or stored on a transitory or non-transitory machine-readable (e.g., computer-readable) storage medium, which may be read and executed by one or more processors. A machine-readable storage medium may be embodied as any storage device, mechanism, or other physical structure for storing or transmitting information in a form readable by a machine (e.g., a volatile or non-volatile memory, a media disc, or other media device).
