Abstract

Methods and apparatuses for operating a portable device based on an accelerometer are described. According to one embodiment of the invention, a movement of a portable device is detected using an accelerometer attached to the portable device. An orientation of the portable device after the movement is determined based on movement data provided by the accelerometer. It is determined whether the portable device is held by a user after the movement based on the movement data provided by the accelerometer. Locations of the hands of the user for holding the portable device are determined based on the orientation of the portable device. At least one interface that is not within the predicted locations of the hands of the user is activated.

Claims

1. A method, comprising:

detecting a movement of a portable device using an accelerometer attached to the portable device;

determining an orientation of the portable device after the movement based on movement data provided by the accelerometer;

determining whether the portable device is held by a user after the movement based on the movement data provided by the accelerometer;

predicting locations of the hands of the user for holding the portable device based on the orientation of the portable device; and

activating at least one interface that is not within the predicted locations of the hands of the user.

2. The method of claim 1, further comprising:

activating at least one interface of the portable device that is best suitable for given the determined orientation; and

optionally deactivating at least one interface of the portable device that is less suitable for the given determined orientation.

3. The method of claim 1, further comprising deactivating at least one interface that is within the predicted locations.

4. The method of claim 1, wherein the at least one interface includes one or more wireless transceiver.

5. The method of claim 4, further comprising:

activating at least one wireless transceiver that communicates with relatively strong signals; and

optionally deactivating at least one wireless transceiver that communicates with relatively weak signals.

6. The method of claim 1, wherein the at least one interface includes one or more speakers.

7. The method of claim 6, further comprising driving at least one speaker to have a best sound effect given the determined orientation of the portable device after the movement.

8. The method of claim 1, wherein the at least one interface includes one or more cameras.

9. The method of claim 1, wherein the at least one interface includes one or more microphones.

10. The method of claim 1, wherein the at least one interface includes one or more video output interfaces.

11. The method of claim 1, wherein the portable device is one of a laptop computer, a tablet PC, a PDA (personal digital assistant), a cellular phone, a personal communicator, and a media player.

12. A machine-readable storage medium having machine-executable instructions stored therein, which when executed by a machine, cause the machine to perform a method, the method comprising:

detecting a movement of a portable device using an accelerometer attached to the portable device;

determining an orientation of the portable device after the movement based on movement data provided by the accelerometer;

determining whether the portable device is held by a user after the movement based on the movement data provided by the accelerometer;

predicting locations of the hands of the user for holding the portable device based on the orientation of the portable device; and

activating at least one interface that is not within the predicted locations of the hands of the user.

13. The machine-readable storage medium of claim 12, wherein the method further comprises:

activating at least one interface of the portable device that is best suitable for given the determined orientation; and

optionally deactivating at least one interface of the portable device that is less suitable for the given determined orientation.

14. The machine-readable storage medium of claim 12, wherein the method further comprises deactivating at least one interface that is within the predicted locations.

15. The machine-readable storage medium of claim 12, wherein the at least one interface includes one or more wireless transceiver.

16. The machine-readable storage medium of claim 15, wherein the method further comprises:

activating at least one wireless transceiver that communicates with relatively strong signals; and

optionally deactivating at least one wireless transceiver that communicates with relatively weak signals.

17. The machine-readable storage medium of claim 12, wherein the portable device is one of a laptop computer, a tablet PC, a PDA (personal digital assistant), a cellular phone, a personal communicator, and a media player.

18. A portable device, comprising:

a processor; and

a memory for storing executable instructions, which when executed from the memory, cause the processor to perform operations, including

detecting a movement of a portable device using an accelerometer attached to the portable device,

determining an orientation of the portable device after the movement based on movement data provided by the accelerometer,

determining whether the portable device is held by a user after the movement based on the movement data provided by the accelerometer,

predicting locations of the hands of the user for holding the portable device based on the orientation of the portable device, and

activating at least one interface that is not within the predicted locations of the hands of the user.

19. The portable device of claim 18, wherein the operations further comprise:

activating at least one interface of the portable device that is best suitable for given the determined orientation; and

optionally deactivating at least one interface of the portable device that is less suitable for the given determined orientation.

20. The portable device of claim 18, wherein the operations further comprise deactivating at least one interface that is within the predicted locations.

21. The portable device of claim 18, wherein the at least one interface includes one or more wireless transceiver.

22. The portable device of claim 21, wherein at least one wireless transceiver that communicates with relatively strong signals is activated, and wherein at least one wireless transceiver that communicates with relatively weak signals is optionally deactivated.

23. The portable device of claim 18, wherein the portable device is one of a laptop computer, a tablet PC, a PDA (personal digital assistant), a cellular phone, a personal communicator, and a media player.
