Abstract

Devices and methods are disclosed for establishing device interaction among electronic devices of an environment. The device has a transmitter, receiver, memory storing interaction rules and a processor for implementing the interaction rules in association with the transmitter, receiver, and other devices of the environment. The device also includes components for performing the device specific functions and a state sensor for determining the logical or physical state of the device. The methods involve detecting a change of state at a device and then communicating in accordance with the interaction rules thereafter. The communication may involve broadcasting change of state messages to the environment, directing change of state messages to specific devices, and directing requests and/or directing replies to requests. Through device interaction, changes of state may automatically occur at one device in response to a change of state at another in order to reduce the burden on the user.

Claims

1. A method of establishing device interaction in an environment having a plurality of devices where each device performs one or more unique functions within the environment with the one or more functions of each device being associated with various states, the method comprising:

detecting a change of state at a first device;

in response to detecting the change of state, referencing rules of device interaction that govern communication between the first device and one or more other devices of the plurality, the rules of device interaction providing an association between the detected change of state, the one or more other devices that are communicated with in response, and the content of the communication between the first device and the one or more other devices; and

communicating with the one or more other devices according to the rules of device interaction in response to detecting the change of state.

2. The method of claim 1, wherein the device interaction rules specify that the device should broadcast the change of state to all devices of the plurality, and wherein the step of communicating with the one or more other devices comprises broadcasting the state of change to all devices of the plurality.

3. The method of claim 1, wherein the device interaction rules specify that the device should direct the change of state to one or more specific devices of the plurality, and wherein the step of communicating with the one or more other devices comprises directing the change of state to the one or more specific devices.

4. The method of claim 1, wherein the device interaction rules specify that the device should direct a request to a specific device of the plurality and receive a reply from the specific device, and wherein the step of communicating with the one or more other devices comprises directing the request to the specific device of the plurality and receiving the reply from the specific device.

5. A method of establishing device interaction in an environment having a plurality of devices where each device performs one or more unique functions within the environment with the one or more functions of each device being associated with various states, the method comprising:

detecting a change of state at a first device; and

in response to detecting the change of state, broadcasting a change of state message to the plurality of devices, the message including an indication of the change of state and an identification of the first device.

6. The method of claim 5, wherein a set of interaction rules are provided for each device, the method further comprising that prior to broadcasting the change of state message, determining from the set of interaction rules that the change of state should be broadcast to all devices of the plurality.

7. The method of claim 5, wherein a set of interaction rules are provided for each device, the method further comprising:

receiving the message at the plurality of devices; and

receiving at the first device a reply from one or more of the plurality of devices.

8. A method of establishing device interaction in an environment having a plurality of devices where each device performs one or more unique functions within the environment with the one or more functions of each device being associated with various states, the method comprising:

detecting a change of state at a first device;

determining a second device of the plurality that is associated with the detected change of state of the first device; and

in response to detecting the change of state, directing a message to a second device, the message including a notification related to the detected change of state and an identification of the first device.

9. The method of claim 8, wherein the notification describes the change of state of the first device.

10. The method of claim 8, wherein interaction rules are provided for the first device, the method further comprising referencing the interaction rules to determine a change of state desired for the second device due to detection of the change of state of the first device and wherein the notification describes the change of state desired for the second device.

11. The method of claim 8, wherein an aggregator is in communication with each device of the plurality and wherein directing the message further comprises:

sending the message to the aggregator; and

forwarding the message from the aggregator to the second device.

12. A method of establishing device interaction in an environment having a plurality of devices where each device performs one or more unique functions within the environment with the one or more functions of each device being associated with various states, the method comprising:

detecting a change of state at a first device; and

in response to detecting the change of state, directing a request to a second device, the request including an indication of a subject matter of the request, and an identification of the first device;

receiving at the second device the request sent by the first device; and

in response to receiving the request, directing a reply to the first device from the second device, the reply including an identification of the second device and the subject matter being requested.

13. The method of claim 12, wherein an aggregator is in communication with each of the plurality of devices, and wherein directing a request comprises sending the request to the aggregator and forwarding the request from the aggregator to the second device.

14. The method of claim 13, wherein directing a reply comprises sending the reply to the aggregator and forwarding the reply from the aggregator to the first device.

15. The method of claim 12, wherein the subject matter of the request includes rules of interaction stored by the second device.

16. The method of claim 12, wherein the subject matter of the request includes a current state of the second device.

17. The method of claim 12, wherein the subject matter of the request includes a list of capabilities of the second device.

18. The method of claim 12, wherein the plurality of devices maintain interaction rules that contain a subscriber list indicating the devices that should receive a message regarding a change of state, and wherein the subject matter of the request includes an instruction to add the first device to the subscriber list of the second device.

19. A device for interacting in an environment having a plurality of devices where each device performs one or more unique functions within the environment with the one or more functions of each device being associated with various states, the device comprising:

a transmitter;

a receiver;

a memory that stores interaction rules of the device;

components that acquire the various states upon performing the one or more unique functions of the device;

a state sensor that is operably coupled to one or more of the components to recognize a current state of the device; and

a processor in communication with the transmitter, receiver, memory, and state sensor, the processor being configured to detect a change of state from the state sensor, reference the memory to find an interaction rule corresponding to the change of state, and utilize the transmitter and receiver to communicate with the other devices of the plurality according to the interaction rule.

20. The device of claim 19, wherein the interaction rules specify that the device should broadcast the change of state to all devices of the plurality.

21. The device of claim 19, wherein the interaction rules specify that the device should direct the change of state to one or more specific devices of the plurality.

22. The device of claim 19, wherein the interaction rules specify that the device should direct a request to a specific device of the plurality and receive a reply from the specific device.

23. The device of claim 19, wherein the components form a television.
