Abstract
Systems and methods for improving power usage of a wireless device are disclosed. The wireless device includes a memory; and at least one processor communicatively coupled to the memory, the at least one processor configured to: determine a change in ambient light received by the wireless device; determine a position of the wireless device; activate a low power image sensor based on at least one of the change in the ambient light or the position of the wireless device; detect a face using the low power image sensor; and turn on a display of the wireless device based on a user face being the face detected.
Claims40
A method performed by a wireless device, the method comprising:
- determining a change in ambient light received by a light sensor of the wireless device;
- determining a position of the wireless device using a motion sensor;
- activating a low power image sensor based on at least one of the change in the ambient light or the position of the wireless device;
- detecting a face using the low power image sensor;
- and
- turning on a display of the wireless device based on an authorized user face being the face detected.
A wireless device, comprising:
- a memory;
- a light sensor;
- a low power image sensor;
- a motion sensor;
- and
- at least one processor communicatively coupled to the memory, the light sensor, the motion sensor and the low power image sensor, the at least one processor configured to:
- determine a change in ambient light received by the light sensor of the wireless device;
- determine a position of the wireless device using the motion sensor;
- activate the low power image sensor based on at least one of the change in the ambient light or the position of the wireless device;
- detect a face using the low power image sensor;
- and
- turn on a display of the wireless device based on an authorized user face being the face detected.
A wireless device, comprising:
- means for determining a change in ambient light received by the wireless device;
- means for determining a position of the wireless device;
- means for activating a low power image sensor based on at least one of the change in the ambient light or the position of the wireless device;
- means for detecting a face using the low power image sensor;
- and
- means for turning on a display of the wireless device based on an authorized user face being the face detected.
A non-transitory computer-readable medium configured to store computer-executable instructions that, when executed by a processor, cause the processor to:
- determine a change in ambient light received by a light sensor of a wireless device;
- determine a position of the wireless device using a motion sensor;
- activate a low power image sensor based on at least one of the change in the ambient light or the position of the wireless device;
- detect a face using the low power image sensor;
- and
- turn on a display of the wireless device based on an authorized user face being the face detected.
