The present invention relates to telecommunications in general, and, more particularly, to a graphical user interface for defining relations among products and services.
As part of a concept known as the “Internet of Things” (IoT), sensor devices communicate information about the environment around them to other devices. To enable this, the IoT comprises a network infrastructure that links physical and virtual objects through the use of data capture and communication capabilities. The network infrastructure of the IoT provides identification of specific objects, sensor monitoring, and connection capability.
The aforementioned features of the IoT serve as the basis for the development of cooperative services and applications, particularly those that are characterized by a high degree of autonomous data capture, event transfer, network connectivity, and interoperability. These applications include home automation; metering of power, gas, water and heating; monitoring of alarm systems, vending machines, medical devices and vital life functions; and tracking and tracing of vehicles and toll collection affecting those vehicles. In regard to home automation, services enabled in part by the IoT include sending a text when a doorbell rings, tweeting a pet owner when a pet's water bowl runs dry, and taking a photograph to be uploaded to a homeowner's Dropbox when motion is detected in the homeowner's garage, to name a few specific associations of sensors with services.
In a related development, the machine-to-machine (M2M) device, software, network and service market is expected to grow rapidly worldwide in the next few years. According to the Cisco Internet Business Solutions Group's (IBSG) April 2011 data, there were about 12.5 billion objects connected to the Internet in 2010 and there will be an estimated 50 billion connected devices by 2020. Key factors that are responsible for such rapid growth of connectivity include the dropping cost of access to the public mobile data network, and of access to wireless data networks in general, and the continually increasing capabilities of these networks.
As the number of connectable devices grows, so does the need to manage the connections between such devices more effectively.
The present invention enables users to create relations between selected products or services, via a user interface and based on cause-and-effect rules. The products or services for which relations can be created are from fields such as home automation, Internet services, and any other situation in which a cause-and-effect relation may be applied.
In accordance with an illustrative embodiment of the present invention, a user interface is presented to a user via a computer system such as a tablet computer. The user interface comprises a graphical user interface (GUI) as part of a computer software application. The GUI disclosed herein features a display that is analogous to that of a slot machine, with a touch-enabled screen that is operated with the user's fingers. The GUI has scrollable, dynamic “rolls,” similar to those of a slot machine and in the form of vertical or horizontal “stripes” of information, which in this context are made up of display icons. These display icons are items that are representative of sensor and actor devices, or of products and/or services that have associated sensor or actor devices.
The user interface presents to the user two rolls, each roll having a displayable series of items. The first roll is a displayable first series of items, including one or more displayed items, and is situated in a display region on a first side (e.g., left side) of the user display. The second roll is a displayable second series of items, including one or more displayed items, and is situated in a display region on a second side (e.g., right side) of the user display. In some embodiments of the present invention, the first series of items is made up of a series of icons that represent “causes” and the second series of items is made up of a series of icons that represent “effects.”
The computer system of the illustrative embodiment presents the rolls of the user interface to the user, in order to enable the user to navigate through the relation management system, to select items and to define relations. A “relation” in this context is an association or a connection between two or more items that are representative of devices or of products and/or services. For example and without limitation, a sensor device associated with a first product or service can be linked to an actor device associated with a second product or service, so that the two devices are configured to telecommunicate with each other.
In a first variation of the illustrative embodiment of the present invention, the icons in the first roll directly represent sensor devices such as, but not limited to, the following: “Thermometer”, “Hygrometer”, “Anemometer”, “Motion Detector”, “Email Server”, and “Light Switch”. The icons in the second roll directly represent actor devices such as, but not limited to, the following: “Light Bulb”, “Heater”, “Air Conditioner”, “Media Player”, “Outgoing-Email Server”, and “Outgoing-SMS Text Server”.
For example, the user can select the “Motion Detector” sensor device as a cause and the “Media Player” actor device as an effect, and can then further define the relationship by specifying that detecting motion in a particular place will activate the playing of a particular music track, in a particular room at home and at a particular time and day. In this case, the cause is the detection of motion, as detected by the motion detector as the sensor device, and the effect is the playing of the music, as implemented by the media player as the actor device.
In a second variation of the illustrative embodiment of the present invention, and at a higher level of abstraction, the icons in the first roll represent products and services such as, but not limited to, the following: Evernote™, Google Latitude™, Twitter™, Gmail™, Belkin Motion™ sensor, and Facebook™. The icons in the second roll represent products and services such as, but not limited to, the following: Belkin Switch™ plug, Thermostat—Nest™, Scenes—Philips Hue™, Email Alert, and SMS Alert.
For example, the user can select “Gmail” as a cause and “Scenes—Philips Hue” as an effect, and can then further define the relationship by specifying that receiving a particular email on the user's Gmail account will activate the selected Hue scene (e.g., “stars pallet”) as a room-lighting effect in a particular room at home, at a particular time and day. In this case, the cause is the arrival of the incoming email, as detected by the user's Gmail account as the “sensor,” and the effect is the activation of the selected Hue scene, as implemented by the Philips Hue Lighting product as the “actor.”
In some embodiments of the present invention, the relation between the cause and effect is defined and previewed in the display region in the middle of the user interface—that is, between the selected cause and selected effect. In having this arrangement, the disclosed GUI reflects graphically and spatially the nature of the relation, in that the settings and relation “happen” between the cause and the effect.
The disclosed graphical user interface is advantageous, in that it enables easy and intuitive navigation, is responsive, maps real-world relations, and has increased usability. Moreover, in the embodiment of the invention operating at the products/services level, the need for a user to have to configure relations directly at the device level is reduced or eliminated.
A first embodiment of the present invention comprises: displaying at least one item in a displayable first series of items, on a display; detecting a selection of a first item from the first series of items; displaying at least one item in a displayable second series of items, on the display, wherein the second series of items is based on the selected first item; detecting a selection of a second item from the second series of items; and transmitting a signal for linking a) a first device represented by the selected first item and b) a second device represented by the selected second item, with each other, based on the detecting of: i) the selection of the first item, and ii) the selection of the second item; wherein the selected first and second items being in spatial alignment with each other on the display provides an indication of the linking of the first and second devices.
A second embodiment of the present invention comprises: a display for: i) displaying at least one item in a displayable first series of items, and ii) displaying at least one item in a displayable second series of items, wherein the second series of items is based on a first item being selected; a processor for: i) detecting the selection of the first item from the first series of items, ii) detecting a selection of the second item from the second series of items; and a transmitter for: i) transmitting a signal for linking a first device represented by the selected first item and a second device represented by the selected second item, with each other, based on the detecting of: a) the selection of the first item, and b) the selection of the second item, wherein the selected first and second items being in spatial alignment with each other on the display provides an indication of the linking of the first and second devices.
A third embodiment of the present invention comprises: displaying at least one cause in a displayable series of causes, on a display; detecting a selection of a cause from the series of causes; displaying at least one effect in a displayable series of effects, on the display, wherein the series of effects is based on the selected cause; detecting a selection of an effect from the series of effects; and transmitting a signal for linking a) a first device that is capable of monitoring for the cause selected and b) a second device that is capable of implementing the effect selected, with each other, such that the selected effect is brought about when the selected cause occurs, wherein the linking is based on the detecting of: i) the selection of the cause, and ii) the selection of the effect.

In accordance with the illustrative embodiment, computer system 101 is mobile and telecommunicates wirelessly. It will clear to those skilled in the art, however, after reading the present disclosure, how to make use and use various embodiments of the present invention in which computer system 101 operates primarily or solely at a fixed position, or is connected via physical media (e.g., cable, wire, etc.) to network 102, or both.
Computer system 101 is illustratively a tablet computer with at least packet data capability provided and supported by network 102. It will be clear to those skilled in the art, however, after reading the present disclosure, how to make and use alternative embodiments where computer system 101 is a desktop, laptop, hand-held computer, smartphone, cell phone, personal digital assistant (PDA), dedicated media player, consumer electronic device, wearable computer, smartwatch, smartglasses (e.g., a Google Glasses™ platform), specialized remote-control unit, other type of personal computer system, other computing device, or any combination thereof, for example and without limitation. Computer system 101 is capable of and configured to, for example and without limitation:
Display 201 is a component that enables computer system 101 to present a user interface to a user according to the illustrative embodiment. Display 201 is well known in the art. In accordance with the illustrative embodiment, display 201 is built into the same enclosure of computer system 101 that also houses system 101's other salient components. In some alternative embodiments of the present invention, display 201 is housed in a physical enclosure separate from the other components depicted in
Computer system 101 comprises an interactive function associated with display 201 such that display 201 is a touch-screen that receives user input—for example, via touching or stroking the surface of display 201. However, it will be clear to those skilled in the art, after reading the present disclosure, how to make and use alternative embodiments wherein the interactivity with display 201 is accomplished in a different way, e.g., stylus, mouse, keyboard, knob (i.e., physical turn-knob or otherwise), etc. The functionality of the user interface and its presentation scheme is described in more detail below and in the accompanying figures.
Processor 202 is a processing device such as a microprocessor that is well known in the art. Processor 202 is configured such that, when operating in conjunction with the other components of computer system 101, processor 202 executes software, processes data, and telecommunicates according to the operations described herein.
Memory 203 is non-transitory and non-volatile computer storage memory technology that is well known in the art (e.g., flash memory, etc.). Memory 203 stores operating system 211, application software 212, and database 213. Operating system 211 is a collection of software that manages, in well-known fashion, computer system 101's hardware resources and provides common services for computer programs, such as those that constitute application software 212.
The specialized application software 212 that is executed by processor 201 according to the illustrative embodiment is illustratively denominated the “relation management logic.” The relation management logic enables computer system 101 to perform the operations of method 400. It should be noted that in some configurations where computer system 101 collaborates with server computing system 103, system 103 also comprises and executes some elements of the relation control logic, for example, when system 103 performs certain operations in response to data received from computer system 101.

In any event, it will be clear to those skilled in the art, after reading the present disclosure, how to make and use computer system 101.
One or more sensors are associated with each causation system 104-m. Each sensor gathers information about the environment that is accessible by the causation system. In some embodiments, a sensor associated with causation system 104-m monitors a particular physical condition in well-known fashion. A sensor associated with causation system 104-m senses a change in the condition being monitored. For example and without limitation, the condition being monitored can be:
As those who are skilled in the art will appreciate, after reading this disclosure, the sensor associated with causation system 104-m can be in a variety of forms, such as a thermometer 311, a motion detector 312, an email server 313, a position determination equipment (PDE) 314, and so on.
Likewise, one or more actors are associated with each affected system 105-n. Each actor performs appropriate actions upon the actor's environment, based either on commands received from another entity making decisions (e.g., a separate middleware decision layer, etc.) or on decisions made by actor itself, or both. The decisions that are made (i.e., by the other entity and/or by the actor itself) are based on one or more causes, as sensed by sensors in one or more causation systems 104-m. Each actor acts upon its environment in well-known fashion. In some embodiments, an actor is or comprises an actuator, as is known in the art. An actor associated with affected system 105-n is capable of receiving, transmitting, processing, and/or relaying data, as well as being able to affect a condition, physical or otherwise, in its environment. For example and without limitation, the condition being affected can be:
As those who are skilled in the art will appreciate, after reading this disclosure, the actor associated with affected system 105-n can be in a variety of forms, such as a light bulb 321 as part of a lighting system, a media player 322 as part of an audio/video system, a heater 323 as part of an environment control system, an outgoing-email server 324 as part of a messaging system, an actor in a water sprinkler system, a robot or robotic arm, a pan/tilt camera, a switch, a motor, a servo mechanism, and so on.
In some embodiments of the present invention, an actor can also be considered a sensor or can be directly associated with a sensor, in the case of one or more of the actors. For example, a state of a light bulb (i.e., “on” or “off”) can be tested and subsequent actions can be defined. As another example, an email sent as an “effect” of one rule can be a “cause” of one or more subsequently defined actions.
The depicted GUI appears and works as a slot machine, being operated with fingers on a touch-enabled screen. This slot-machine GUI has scrollable, dynamic “rolls” in the form of vertical or horizontal “stripes” of information, which in this context are display icons. These display icons are items that are representative of products or services, which have associated sensor devices or actor devices in some embodiments of the present invention. In some embodiments of the present invention, one or more of the display icons are directly representative of sensor devices or actor devices themselves.
User interface 301 presents to the user two rolls, each roll having a displayable series of items. The first roll is a displayable first series of items 303, including displayed item 302, and is situated in a display region on the left side of user interface 301, as depicted. The second roll is a displayable second series of items 305, including displayed item 304, and is situated in a display region on the right side of user interface 301, as depicted. First series 303 is made up of a series of icons representing “causes,” and second series 305 is made up of a series of icons representing “effects.”
Computer system 101 presents the rolls of user interface 301 to the user, in order to enable the user to navigate through the relation management system, to select items and to define relations. A relation in this context is an association or a connection between two or more items representative of products, services, and/or devices. For example, a sensor device (e.g., motion detector 312, etc.) can be linked to an actor device (e.g., media player 322, etc.), so that the two devices are capable of telecommunicating with each other or are, in fact, in communication with each other.
As illustrated specifically in
For example, the user can select “Motion Detector” as a cause and “Media Player” as an effect, and can then further define the relationship by specifying that detecting motion in a particular place will activate the playing of a particular music track, in a particular room at home and at a particular time and day. In this case, the cause is the detection of motion, as detected by motion detector 312 as the sensor device, and the effect is the playing of the music, as implemented by media player 322 as the actor device.
In some other embodiments of the present invention, a sensor device can be associated with a first product or service, and an actor device can be associated with a second product or service. In this case, the user manages the establishment of the relation at a product/service level, which is a higher level of abstraction than the device level. This higher level of abstraction involving products and/or services is now discussed.
As illustrated specifically in
For example, the user can select “Gmail” as a cause and “Scenes—Philips Hue” as an effect, and can then further define the relationship by specifying that receiving a particular email on the user's Gmail account will activate the selected Hue scene (e.g., “stars pallet”) as a room-lighting effect in a particular room at home, at a particular time and day. In this case, the cause is the arrival of the incoming email, as detected by the user's Gmail account as the “sensor,” and the effect is the activation of the selected Hue scene, as implemented by the Philips Hue Lighting product as the “actor.” In this example, software within an incoming email server serves as the actual sensor device and a smart light bulb serves as the actual actor device.
Various alternative embodiments of user interface 301 are possible, as those who are skilled in the art will appreciate after reading the present disclosure. First, as depicted in
At task 405, computer system 101 displays at least one item in a displayable first series of items, on display 201. System 101 determines a set of items to display, out of all of the possible displayable items, based on predetermined criteria. For example, system 101 might display a set of items that is user-independent (e.g., a general default list), or system 101 might display a set of items that is user-specific (e.g., based a user attribute, based on a user demographic, based on a user behavioral pattern, based on what the user had previously selected as an effect, etc.). In some embodiments of the present invention, at least one item related to or representative of an advertisement is displayed, which can be user-independent or user-specific as well.
At task 410, computer system 101 detects a selection of an item from the first series of items. Task 410 is described below and in
At task 415, computer system 101 displays at least one item in a displayable second series of items, on display 201. In accordance with the illustrative embodiment, system 101 determines which subset to display, out of all of the possible displayable items, based on the selected item detected at task 410. For example, system 101 might display a first subset of items to display based on a first selected item having been detected at task 410, whereas system 101 might display a second subset of items to display based on a second selected item having been detected at task 410, wherein the first and second subset might or might not have any items in common. In some embodiments of the present invention, at least one item related to or representative of an advertisement is displayed, based on the selected item detected at task 410.
At task 420, computer system 101 detects a selection of an item from the second series of items. Task 420 is described below and in
At task 425, computer system 101 optionally displays one or more choices as part of a user menu in a third region of the display. The choices displayed offer user-selectable options to the user and are based on a combination of the selected first and second items. In accordance with the illustrative embodiment, system 101 determines i) what information content to display as part the user menu or ii) whether to display any content at all, or both, based on the selected item detected at task 410 or on the selected item detected at task 420, either alone or in combination with each other. The user menu can include a set of options and/or conditions for the sensor; for example, a condition for a temperature sensor might be “falls below 10 degrees.” The user menu also can include a set of available actions for the actor; for example, an available action for a heater might be “turn on.” An example of the third region of the display is depicted in
At task 430, computer system 101 detects, in well-known fashion, a selection of at least one option specifying one or more conditions, from the user-selectable options displayed at task 425. System 101 uses the selection of the option or options to define, at least in part, the relation between the selected first and second items and between their underlying devices.
At task 435, computer system 101 links i) a first device that constitutes causation system 104-m and that is represented by the selected first item and ii) a second device that constitutes affected system 105-n and that is represented by the selected second item, with each other. Linking comprises one or both of i) applying the relation between the condition specified for the selected sensor and the action specified for the selected actor, and ii) establishing the connectivity between the selected sensor and actor. In accordance with the illustrative embodiment, the linking is based on i) the detecting at task 410 of the selection of the first item and ii) the detecting at task 420 of the selection of the second item. Task 435 is described below and in
After task 435, computer system 101 returns to a processing state in which a user of user interface 301 is able to select a different pair of items of the purpose of linking together a different pair of devices.
At task 505, computer system 101 detects the selection of the first item as described at task 410. System 101 does this, at least in part, by determining whether the first item has been moved, by a user of display 201, to within a first display region of user interface 301, in well-known fashion.
At task 510, upon determining that the first item has been moved to within the first display region, computer system 101 concludes that the user has selected the first item.
Consistent with tasks 505 and 510,
Computer system 101 determines that the movement of item 601 into region 602, followed by the removal of the user's finger from the icon, has happened and, as a result, concludes that the user has selected Belkin Motion Sensor as a “cause.” In some embodiments of the present invention, computer system 101 then displays one or more captions and/or selection buttons that are relevant to the selected item, in the center of the display.
Computer system 101 then displays graphical and/or textual elements in display region 603, shown in
Computer system 101 can also display other pertinent information that is contextual to the selected cause item. For example, system 101 displays login prompt 604 (i.e., “Connect to account”) for providing access to an account that is associated with the selected cause. As another example, system 101 displays advertising prompt 605 (i.e., “Buy product”) for advertising something about the selected cause.
At task 705, computer system 101 detects the selection of the second item as described at task 420. System 101 does this, at least in part, by determining whether the second item has been moved, by a user of display 201, to within a second display region of user interface 301, displayed on display 201, in well-known fashion.
At task 710, upon determining that the second item has been moved to within the second display region, computer system 101 concludes that the user has selected the second item.
Consistent with tasks 705 and 710,
Computer system 101 determines that the movement of item 801 into region 802, followed by the removal of the user's finger from the icon, has happened and, as a result, concludes that the user has selected Scenes—Philips Hue as an “effect.”
Computer system 101 then displays one or more choices as part of user menu 803 in display region 804, shown in
In some embodiments of the present invention, the prompts in user menu 803 are based on one or more relations already established. For example, as previously discussed, an actor can be considered a sensor or can be directly associated with a sensor. For example, menu 803 can provide the option to test a state of a light bulb (i.e., “on” or “off”) and to define subsequent actions. As another example, menu 803 can provide the option to have an email, which was sent as an “effect” of one rule, be a “cause” of one or more subsequently defined actions. In other words, an effect or actor in a previously-created first relation can be configured via menu 803 as a cause or sensor in a second relation being created by the user.
At task 905, computer system 101 identifies a first device that is represented by the selected first item. For example, a relationship between i) each icon in the first series and ii) one or more associated first devices, can be maintained in database 213 and accessed from the database by system 101.
At task 910, computer system 101 identifies a second device that is represented by the selected second item. For example, a relationship between i) each icon and the second series and ii) one or more associated second devices, can be maintained in database 213 and accessed from the database by system 101.
At task 915, computer system 101 applies the relation between i) one or more specified conditions, if any, for the selected sensor device and ii) one or more specified available actions, if any, for the selected actor device. These conditions are a part of the one or more options selected by the user and detected by system 101 at task 430. A purpose of this is to establish when a sensor device transmits a signal for an actor device, or when an actor device performs an appropriate action based on a signal transmitted by a sensor device, or both. For example, suppose that the specified condition for a motion sensor is “motion detected” and the specified action for a light bulb (actor) is “blink red five times”. In this case, computer system 101 transmits to one or more of server-computing system 103, causation system 104-m (wherein m corresponds to the selected sensor), and affected system 105-n (wherein n corresponds to the selected actor), information (e.g., one or more signals, one or more messages, one or more records, etc.) representing the relation of the light bulb blinking red five times when the motion sensor detects motion.
At task 920, computer system 101 connects logically the first device and the second device together, such that they are able to communicate with each other, in well-known fashion. For example, computer system 101 can access each device and transmit one or more signals that inform each device of i) the presence of the other device and ii) the relationship between each other. As another example, computer system 101 can transmit one or more signals to server-computing system 103, which in turn connects the first and second devices together.
At task 925, computer system 101 optionally indicates to the user that the selected first and second items are linked together, or the corresponding first and second devices are linked together, or both. The selected first and second items being in spatial alignment with each other on the display, in this case horizontally as shown in
It is to be understood that many variations of the invention can easily be devised by those skilled in the art after reading this disclosure and that the scope of the present invention is to be determined by the following claims.
