Abstract

A device implementing a system for power management includes at least one processor configured to, detect first gesture state associated with motion of a device, the first gesture state being associated with meeting a first threshold of device motion, and set, in response to detecting the first gesture state, the device to a first power state. The at least one processor is further configured to detect, subsequent to detecting the first gesture state, a second gesture state associated with motion of the device, the second gesture state being associated with meeting a second threshold of device motion, and set, in response to detecting the second gesture state, the device to a second power state. The at least one processor is further configured to update, based on setting the device to the second power state, image data on a display of the device.

First claim

What is claimed is:

1. A method, comprising:
detecting a first gesture state associated with motion of a device in a current power state, the first gesture state being detected when the motion of the device exceeds a first threshold of device motion;
changing, in response to detecting the first gesture state, the current power state of the device to a first power state associated with a first power consumption level that corresponds to activating an application processor and kernel space of the device without activating a user space of the device, the user space corresponding to resources for updating image data on a display of the device, the first power consumption level being higher than a current power consumption level of the current power state;
detecting, subsequent to detecting the first gesture state, a second gesture state associated with motion of the device, the second gesture state being detected when motion of the device exceeds a second threshold of device motion;
setting, in response to detecting the second gesture state, the device to a second power state associated with a second power consumption level that corresponds to activating a user space of the device in addition to the activated application processor and kernel space, the second power consumption level being higher than the first power consumption level; and
updating, based on setting the device to the second power state, the image data on the display of the device.

2. The method of claim 1 , wherein the first threshold corresponds to a first confidence score of user intent to view the display based on motion of the device, and
wherein the second threshold corresponds to a second confidence score of user intent to view the display based on motion of the device, the second confidence score exceeding the first confidence score.

3. The method of claim 1 , wherein the first gesture state and the second gesture state relate to a wrist-raise gesture of the device.

4. The method of claim 3 , wherein the device is a smartwatch, and
wherein updating the image data is for displaying a first frame upon completion of the wrist-raise gesture.

5. The method of claim 1 , wherein the first and second thresholds of device motion are subject to respective time restrictions.

6. The method of claim 5 , further comprising:
associating the first gesture state with a cancel operation in a case where the second gesture does not meet its respective time restriction,
wherein the cancel operation corresponds to refraining from setting the device to the second power state and refraining from updating the image data.

7. The method of claim 1 , further comprising:
increasing a brightness of the display in response to detecting the first gesture state and prior to detecting the second gesture state.

8. The method of claim 1 , wherein the user space corresponds to system memory allocated to running an application on the device.

9. A device, comprising:
at least one processor; and
a memory including instructions that, when executed by the at least one processor, cause the at least one processor to:
detect a first gesture state associated with motion of the device, the first gesture state being detected when the motion of the device exceeds a first threshold of device motion;
change, in response to detecting the first gesture state, a current power state of the device to a first power state associated with a first power consumption level that corresponds to activating an application processor of the device, the first power consumption level being higher than a current power consumption level of the current power state;
detect, subsequent to detecting the first gesture state, a second gesture state associated with motion of the device, the second gesture state being detected when motion of the device exceeds a second threshold of device motion;
set, in response to detecting the second gesture state, the device to a second power state associated with a second power consumption level that corresponds to activating a user space of the device in addition to the activated application processor, the user space corresponding to resources for updating image data on a display of the device, the second power consumption level being higher than the first power consumption level; and
update, based on setting the device to the second power state, the image data on the display of the device.

10. The device of claim 9 , wherein the first threshold corresponds to a first confidence score of user intent to view the display based on motion of the device, and
wherein the second threshold corresponds to a second confidence score of user intent to view the display based on motion of the device, the second confidence score exceeding the first confidence score.

11. The device of claim 9 , wherein the first gesture state and the second gesture state relate to a wrist-raise gesture of the device.

12. The device of claim 11 , wherein the device is a smartwatch, and
wherein updating the image data is for displaying a first frame upon completion of the wrist-raise gesture.

13. The device of claim 9 , wherein the first and second thresholds of device motion are subject to respective time restrictions.

14. The device of claim 13 , wherein the instructions further cause the at least one processor to:
associate the first gesture state with a cancel operation in a case where the second gesture does not meet its respective time restriction,
wherein the cancel operation corresponds to refraining from setting the device to the second power state and refraining from updating the image data.

15. The device of claim 9 , wherein the instructions further cause the at least one processor to:
increase a brightness of the display in response to detecting the first gesture state and prior to detecting the second gesture state.

16. The device of claim 9 , wherein the user space corresponds to system memory allocated to running an application on the device.

17. A computer program product comprising code, stored in a non-transitory computer-readable storage medium, the code comprising:
code to detect a first gesture state associated with motion of a device, the first gesture state being detected when the motion of the device exceeds a first threshold of device motion;
code to change, in response to detecting the first gesture state, a current power state of the device to a first power state associated with a first power consumption level that corresponds to activating an application processor of the device, the first power consumption level being higher than a current power consumption level of the current power state;
code to detect, subsequent to detecting the first gesture state, a second gesture state associated with motion of the device, the second gesture state being detected when motion of the device exceeds a second threshold of device motion;
code to set, in response to detecting the second gesture state, the device to a second power state associated with a second power consumption level that corresponds to activating a user space of the device, the user space corresponding to resources for updating image data on a display of the device, the second power consumption level being greater than the first power consumption level; and
code to update, based on setting the device to the second power state, the image data on the display of the device,
wherein the first gesture state and the second gesture state relate to a wrist-raise gesture of the device.
