Abstract

Techniques for display rotation are disclosed. In one aspect, raw angular motion sensor (AMS) data can be accessed. A motion state of the mobile device can be determined based at least in part on processing the raw AMS data. AMS data can be further processed to determine whether to perform a rotation of the display image based at least in part on applying at least one pre-defined criterion to the AMS data.

Claims

1. A method comprising:

accessing, by a first processor, raw angular motion sensor (AMS) data from an AMS configured to sense angular motion of a mobile device having a display capable of rendering a display image;

determining a motion state of the mobile device based at least in part on the raw AMS data;

in response to determining that the motion state of the mobile device is relative motion, initiating transmission of AMS data from the first processor to a second processor; and

processing the AMS data by the second processor to determine whether to perform a rotation of the display image, where the determination of whether to rotate the display image is based at least in part on applying at least one pre-defined criterion to the AMS data.

2. The method of claim 1, further comprising, in response to determining that the at least one pre-defined criterion has been met, execution of instructions by the second processor to perform the rotation of the display image of the mobile device.

3. The method of claim 2, where the rotation of the display image is either from landscape to portrait orientation, or from portrait to landscape orientation.

4. The method of claim 1, wherein the determining the state of motion of the mobile device based at least in part on the raw AMS data further comprises determining the state of motion using a relative motion detection (RMD) algorithm.

5. The method of claim 4, wherein the state of motion of the mobile device is selected from the group consisting of:

at rest, in motion, at relative rest, and in relative motion.

6. The method of claim 1, wherein the accessing of raw data from the AMS by the first processor is halted when the mobile device transitions from a state of motion to a state of rest.

7. The method of claim 6, wherein the determining the motion state of the mobile device further comprises receiving a motion interrupt signal at the first processor to initiate the access of AMS data when the mobile device transitions from a state of rest to a state of motion.

8. An apparatus comprising:

a first processor configured to;

access raw angular motion sensor (AMS) data from an angular motion sensor (AMS),

execute a relative motion detection (RMD) algorithm to determine a relative motion state of a mobile device, and

determine whether to transmit AMS data based at least in part on a result of the RMD algorithm; and

a second processor configured to;

receive and process the AMS data to make a determination as to whether to rotate a display image on a display of the mobile device, where the determination is based at least in part on applying at least one pre-defined criterion to the AMS data.

9. The apparatus of claim 8, wherein the second processor is further configured to rotate the display image from landscape to portrait orientation, or from portrait to landscape orientation, in response to the determination that the at least one pre-defined criterion has been met

10. The apparatus of claim 8, wherein to determine the relative state of motion of the mobile device is based at least in part on the raw AMS data.

11. The apparatus of claim 8, wherein the relative state of motion of the mobile device is selected from the group consisting of:

at rest, in motion, at relative rest, and in relative motion.

12. The apparatus of claim 8, wherein the angular motion sensor (AMS) is configured to:

sense a motion of the mobile device and

generate and transmit the raw AMS data to the first processor.

13. The apparatus of claim 12, wherein the AMS is further configured to send a motion interrupt signal to the first processor.

14. The apparatus of claim 12, wherein the first processor and/or AMS is located in a haptic sleeve or other peripheral device.

15. An apparatus comprising:

an angular motion sensor (AMS) configured to sense angular motion of a mobile device having a display capable of rendering a display image, and configured to generate and transmit raw AMS data to a processor, wherein the processor is configured to;

access raw AMS data;

execute a relative motion detection (RMD) algorithm to determine a relative state of motion of the mobile device; and

make a determination as to whether to rotate the display image based at least in part on a result of a RMD algorithm.

16. The apparatus of claim 15, wherein the processor is further configured to rotate the display image, from landscape to portrait orientation, or from portrait to landscape orientation, in response to a determination that a pre-defined rotation or angular change threshold is exceeded.

17. The apparatus of claim 15, wherein the relative state of motion of the mobile device is selected from the group consisting of:

at rest, in motion, at relative rest, and in relative motion.

18. The apparatus of claim 15, wherein the AMS is configured to halt transmission of data to the processor when the mobile device transitions from a state of motion to a state of rest.

19. The apparatus of claim 18, wherein the AMS is further configured to send a motion interrupt signal to the processor and to initiate transmission of AMS data when the mobile device transitions from a state of rest to a state of motion.

20. The apparatus of claim 19, wherein the AMS is located in a haptic sleeve or other peripheral device.
