Abstract

Pending execution of a sensor function for use in operation of an application executing on a computing device may be determined. At least a first sensor and a second sensor associated with the computing device may be identified, the first sensor and the second sensor both providing at least a portion of the sensor function. A current context associated with the pending execution of the sensor function may be determined, the current context being defined in terms of context parameters. Selection criteria defined in terms of the context parameters may be accessed, and the first sensor may be selected to execute the sensor function for the application, based on the selection criteria and the current context.

Claims

1. A computer system including a non-transitory computer-readable storage medium having instructions that are readable by at least one processor, the computer system comprising:

an input handler configured to cause the at least one processor to determine a pending execution of a sensor function for use in operation of an application executing on a computing device, and to identify at least a first sensor and a second sensor associated with the computing device, the first sensor and the second sensor both providing at least a portion of the sensor function, the first sensor having higher power requirements than the second sensor;

a context monitor configured to cause the at least one processor to determine a current context associated with the pending execution of the sensor function, the current context being defined in terms of context parameters, the context parameters including a prediction of a re-charge event with respect to the computing device; and

a sensor selector configured to cause the at least one processor to access selection criteria defined in terms of the context parameters, and to select the first sensor to execute the sensor function for the application, based on the selection criteria and the current context.

2. The computer system of claim 1 wherein the input handler is configured to determine the pending execution including receiving a request for the operation of the application.

3. The computer system of claim 2 wherein the input handler is configured to determine a result of the operation and to determine the sensor function of the first sensor and the second sensor, from which the result may be obtained.

4. The computer system of claim 1, wherein the sensor function includes sensing of a current location of the computing device.

5. The computer system of claim 1 wherein the context parameters include one or more of a current power level of the computing device, a current power type of the at least one computing device, user preferences of a user of the at least one computing device, a relative speed of the first sensor and the second sensor in executing the sensor function, a relative reliability of the first sensor and the second sensor in executing the sensor function, a location of the user of the at least one computing device, available processing resources of the computing device, available memory resources of the at least one computing device, and application requirements of the application.

6. The computer system of claim 1, wherein the current context includes current values of previously-collected values of the context parameters.

7. The computer system of claim 6, wherein the current values include historical usage patterns of a user of the application.

8. The computer system of claim 1 wherein the selection criteria includes at least one algorithm for evaluating the existing values of the context parameters of the current context relative to one another to thereby select the first sensor.

9. The computer system of claim 1 wherein the sensor selector is configured to provide the selection of the first sensor to a user of the application, and to receive an indication from the user as to the acceptability of the selection.

10. The system of claim 1, wherein the input handler is configured to communicate with the first sensor and the second sensor using sensor-specific communications protocols, and the sensor selector is configured to translate the sensor-specific communication protocols to thereby communicate with the application using an application-specific communications protocol.

11. The system of claim 1, wherein the sensor selector is configured to cause the at least one processor to select the first sensor based on a first comparison of the selection criteria and the current context, and the context monitor is configured to determine an updated current context that exists at a later time during the operation of the application, and wherein the sensor selector is further configured to dynamically switch between the first sensor and the second sensor at the later time, including deactivating the first sensor, based on a second comparison of the selection criteria with the updated current context.

12. The system of claim 1, wherein, prior to the selection of the first sensor, the sensor selector is configured to activate the first sensor and the second sensor simultaneously and to use a first-received sensor output in the operation of the application.

19. The system of claim 1, wherein the input handler, context monitor, and sensor selector are at least partially included within an application program interface (API) of the application.

13. A computer-implemented method including executing instructions stored on a computer-readable medium, the method comprising:
