Low-power hand-tracking system for wearable device

A computing apparatus comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, configure the apparatus to:
• poll a proximity sensor of a wearable device to detect a proximity event, the wearable device comprising a low-power processor and a high-power processor;
• in response to detecting the proximity event, detect, without recognizing for a number of tires, a gesture of a user of the wearable device using proximity data from the proximity sensor by operating a low-power hand-tracking application on the low-power processor;
• and
• end an operation of the low-power hand-tracking application and activate the high-power processor in response to detecting without recognizing for the number of tries that exceeds the preset number of tries the gesture based on the proximity data.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:

• poll a proximity sensor of a wearable device to detect a proximity event, the wearable device comprising a low-power processor and a high-power processor;
• in response to detecting the proximity event, detect, without recognizing for a number of tires, a gesture of a user of the wearable device using proximity data from the proximity sensor by operating a low-power hand-tracking application on the low-power processor;
• and
• end an operation of the low-power hand-tracking application and activate the high-power processor in response to detecting without recognizing for the number of tries that exceeds the preset number of tries the gesture based on the proximity data.
