Abstract

Techniques are described for providing information about a current state that is modeled with multiple state attributes. In some situations, the providing includes receiving from a module a request related to the modeling of the current state with the multiple state attributes. In such situations, the providing further includes, without further intervention related to the request by the module, determining that the request cannot currently be satisfied, and indicating to the module that the request cannot currently be satisfied, monitoring at later times after the indicating to determine whether the request can be satisfied, and indicating to the module that the request can be satisfied if it is determined at one of the later times that the request can currently be satisfied.

Claims

1. A computer-implemented method for providing information about a current activity of a user that is modeled with multiple state attributes, the method comprising:

employing a processor within a first computer executing computer executable instructions to implement the following acts;

by a mediator module;

receiving from a consumer module a request related to the modeling of the current activity of the user with at least one attribute of user activity of the multiple state attributes, wherein the consumer module registers with the mediator module to receive the at least one attribute of the user activity when the at least one attribute becomes available;

sending a first request to a mediator module in another computer, the first request requesting at least one value related to a physical environment of the user;

in response to the first request, receiving at least one value related to a physical environment of the user and deriving the at least one attribute of the user activity to model the current activity of the user; and

sending a second request to a mediator module in another computer, the second request requesting the mediator module to perform a task.

2. The method of claim 1, further comprising:

receiving from the consumer module an indication of a condition related to a value of the at least one attribute of the multiple state attributes such that the consumer module desires to know when the condition has been satisfied;

detecting changes in the value of the at least one attribute to determine whether the condition is satisfied; and

when it is determined that the condition is satisfied, notifying the consumer module that the condition is satisfied.

3. The method of claim 2, wherein the condition relates to the at least one attribute having a specified value.

4. The method of claim 1, further comprising, by the mediator module, determining whether a source is currently available on the first computer to supply the at least one value related to a physical environment of the user.

5. The method of claim 4, wherein the determining whether the source is currently available on the first computer occurs before sending the first request to the mediator module in another computer.

6. The method of claim 5, further comprising monitoring to detect when a value for a specified state attribute is received.

7. The method of claim 6, wherein the monitoring involves detecting when a source indicates an ability to supply values for the specified state attribute.

8. The method of claim 1, wherein deriving the at least one attribute of the user activity comprises applying at least one mediation technique to select at least one value for a specified state attribute from among values provided by a plurality of sources of supply, the sources of supply comprising at least one server module on the first computer and the mediator module in the another computer.

9. The method of claim 8, further comprising monitoring to determine when at least one of the plurality of sources has a value for the specified state attribute.

10. A computer-readable medium having computer-executable instructions stored thereon for controlling a wearable computer to implement a mediator module that performs acts relating to providing information about a current activity of a user that is represented with multiple attributes, the acts comprising:

receiving from a consumer module on the wearable computer a request for a named attribute of user activity of the multiple attributes related to the modeling of the current activity of the user;

determining a source of a value of the named attribute;

when the determined source is on the wearable computer, obtaining the value of the named attribute from the source on the wearable computer; and

when the determined source is on another computer, requesting from another mediator module on the other computer the value, the requesting comprising renaming the named attribute.

11. The computer-readable medium of claim 10, wherein the acts further comprise:

sending a request to register with the another mediator module on the other computer.

12. The computer-readable medium of claim 10, wherein the acts further comprise:

receiving a second request from a second mediator module on a second other computer;

determining if security approval is needed for processing the second request; and

conditionally processing the second request if the security approval is not needed or is satisfied.

13. The computer-readable medium of claim 12, wherein the acts further comprise:

in response to the second request, obtaining a second value from the source on the wearable computer; and

returning the value to the second mediator module.

14. The computer-readable medium of claim 13, wherein the acts further comprise:

sending a request to the second mediator module to perform a task.

15. A computing device for providing information about a current activity of a user that is represented with multiple attributes, comprising:

at least one processor that executes the following computer executable components resident on a computer readable medium;

an attribute request receiver component adapted to;

receive from a client module a request related to the modeling of the current activity of the user with a higher level of abstraction attribute of user activity of the multiple state attributes; and

derive the higher level of abstraction attribute from a plurality of lower level of abstraction attributes related to a physical environment of the user; and

an attribute request satisfier component adapted to;

determine a respective source of a value for each of the plurality of lower level of abstraction attributes;

when a determined source of a value an attribute of the plurality of lower level of abstraction attributes is on the computing device, obtain a respective one of the values from the source; and

when a determined source of a value of an attribute of the plurality of lower level of abstraction attributes is on another computing device, obtain a respective one of the values from an attribute request satisfier component on the other computing device.

16. The computing device of claim 15, wherein the attribute request receiver component is further adapted to:

determine whether the request can currently be satisfied; and

indicate to the client module that the request can be satisfied after it is satisfied.

17. The computing device of claim 15, further comprising multiple sources and multiple clients executing in memory.

18. The computing device of claim 15, wherein the client module comprises at least one consumer of context information about a current state of a user of a wearable computer.

19. The computing device of claim 15, wherein the higher level of abstraction attribute indicates that the user is engaged in an activity comprising jogging.

20. The computing device of claim 15, wherein the higher level of abstraction attribute indicates the user'"'"'s emotional state.
