LOW-POWER HAND-TRACKING SYSTEM FOR WEARABLE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17851465 titled 'LOW-POWER HAND-TRACKING SYSTEM FOR WEARABLE DEVICE

Simplified Explanation

The patent application describes a method for a low-power hand-tracking system using a wearable device with a proximity sensor. Here are the key points:

  • The method involves polling the proximity sensor of the wearable device to detect a proximity event.
  • The wearable device has both a low-power processor and a high-power processor.
  • Upon detecting the proximity event, a low-power hand-tracking application is operated on the low-power processor using proximity data from the sensor.
  • The operation of the hand-tracking application can end in three ways:
 * By detecting and recognizing a gesture based on the proximity data.
 * By detecting a gesture without recognizing it based on the proximity data.
 * By detecting a lack of activity from the proximity sensor within a timeout period based on the proximity data.

Potential Applications

  • Virtual reality and augmented reality systems
  • Gaming and interactive entertainment
  • Gesture-based control systems for various devices and appliances

Problems Solved

  • Reduces power consumption by utilizing a low-power processor for hand-tracking applications.
  • Provides efficient and accurate hand-tracking capabilities using proximity data from a wearable device.
  • Enables gesture recognition and control without the need for continuous hand-tracking, conserving power.

Benefits

  • Extended battery life for wearable devices by utilizing a low-power processor for hand-tracking applications.
  • Improved user experience with accurate and responsive hand-tracking capabilities.
  • Enables gesture-based control in various applications without draining the device's power.


Original Abstract Submitted

A method for a low-power hand-tracking system is described. In one aspect, a method includes polling a proximity sensor of a wearable device to detect a proximity event, the wearable device includes a low-power processor and a high-power processor, in response to detecting the proximity event, operating a low-power hand-tracking application on the low-power processor based on proximity data from the proximity sensor, and ending an operation of the low-power hand-tracking application in response to at least one of: detecting and recognizing a gesture based on the proximity data, detecting without recognizing the gesture based on the proximity data, or detecting a lack of activity from the proximity sensor within a timeout period based on the proximity data.
