Abstract

In one embodiment an electronic device comprises a display, a motion sensor, one or more wireless communication devices, and logic configured to receive, in the controller, data indicating that the controller is in motion, determine a velocity of the controller, and activate a first location service to determine a coarse location of the controller when the velocity of the controller falls above a predetermined threshold for a predetermined period of time. Other embodiments may be described.

Claims

1. A context aware apparatus, comprising:

logic, at least partially including hardware logic, configured to;

receive, in the controller, data indicating that the controller is in motion;

determine a velocity of the controller; and

activate a first location service to determine a coarse location of the controller when the velocity of the controller falls above a predetermined threshold for a predetermined period of time.

2. The context aware apparatus of claim 1, wherein the logic is further configured to:

define a first region around the coarse location; and

determine whether at least one part of one or more geofences overlaps with the first region.

3. The context aware apparatus of claim 2, wherein the logic is further configured to suspend use of the first location service in response to a determination that no geofences fall within the first region.

4. The context aware apparatus of claim 3, wherein the logic is further configured to:

activate a wireless fidelity network scanner in response to a determination that one or more geofences fall within the first region; and

determine a location from one or more wireless fidelity broadcast beacons.

5. The context aware apparatus of claim 4, wherein the logic is further configured to suspend use of the wireless fidelity network scanner in response to a failure to detect one or more wireless fidelity broadcast beacons within a predetermined time.

6. The context aware apparatus of claim 4, wherein the logic is further configured to:

activate a global positioning service (GPS) location service in response to a determination that one or more geofences fall within the first region.

7. The context aware apparatus of claim 6, wherein the logic is further configured to:

determine a location from the GPS location service.

8. The context aware apparatus of claim 6, wherein the logic is further configured to determine whether the apparatus has reached a geofence threshold, and in response to perform at least one of:

update a location of the context area apparatus using the GPS location service;

or

generating an alert.

9. The context aware apparatus of claim 6, wherein the logic is further configured to:

provide the location of the controller to a processor separate from the controller.

10. The context aware apparatus of claim 6 wherein the logic is further configured to revert to a standby state when the context aware apparatus remains stationary for a predetermined period of time.

11. An electronic device, comprising:

a display;

a motion sensor;

one or more wireless communication devices;

logic configured to;

receive, in the controller, data indicating that the controller is in motion;

determine a velocity of the controller; and

activate a first location service to determine a coarse location of the controller when the velocity of the controller falls above a predetermined threshold for a predetermined period of time.

12. The electronic device of claim 11, wherein the logic is further configured to:

define a first region around the coarse location; and

determine whether at least one part of one or more geofences overlaps with the first region.

13. The electronic device of claim 12, wherein the logic is further configured to suspend use of the first location service in response to a determination that no geofences fall within the first region.

14. The electronic device of claim 13, wherein the logic is further configured to:

activate a wireless fidelity network scanner in response to a determination that one or more geofences fall within the first region; and

determine a location from one or more wireless fidelity broadcast beacons.

15. The electronic device of claim 14, wherein the logic is further configured to suspend use of the wireless fidelity network scanner in response to a failure to detect one or more wireless fidelity broadcast beacons within a predetermined time.

16. The electronic device of claim 14, wherein the logic is further configured to:

activate a global positioning service (GPS) location service in response to a determination that one or more geofences fall within the first region.

17. The electronic device of claim 16, wherein the logic is further configured to:

determine a location from the GPS location service.

18. The electronic device of claim 16, wherein the logic is further configured to determine whether the apparatus has reached a geofence threshold, and in response to perform at least one of:

updating a location of the context area apparatus using the GPS location service;

or

generating an alert.

19. The electronic device of claim 16, wherein the logic is further configured to:

provide the location of the controller to a processor separate from the controller.

20. The electronic device of claim 16 wherein the logic is further configured to revert to a standby state when the context aware apparatus remains stationary for a predetermined period of time.

21. A computer program product comprising logic instructions stored on a tangible computer readable medium which, when executed by a controller, configure the controller to:

receive, in the controller, data indicating that the controller is in motion;

determine a velocity of the controller; and

activate a first location service to determine a coarse location of the controller when the velocity of the controller falls above a predetermined threshold for a predetermined period of time.

22. The computer program product of claim 21 comprising logic instructions stored on a tangible computer readable medium which, when executed by the controller, configure the controller to:

define a first region around the coarse location; and

determine whether at least one part of one or more geofences overlaps with the first region.

23. The computer program product of claim 22, wherein the logic is further configured to suspend use of the first location service in response to a determination that no geofences fall within the first region.

24. The computer program product of claim 23, wherein the logic is further configured to:

activate a wireless fidelity network scanner in response to a determination that one or more geofences fall within the first region; and

determine a location from one or more wireless fidelity broadcast beacons.

25. The computer program product of claim 24, wherein the logic is further configured to suspend use of the wireless fidelity network scanner in response to a failure to detect one or more wireless fidelity broadcast beacons within a predetermined time.

26. The computer program product of claim 24, wherein the logic is further configured to:

activate a global positioning service (GPS) location service in response to a determination that one or more geofences fall within the first region.

27. The computer program product of claim 26, wherein the logic is further configured to:

determine a location from the GPS location service.

28. The computer program product of claim 26, wherein the logic is further configured to determine whether the apparatus has reached a geofence threshold, and in response to perform at least one of:
