US 11,893,159 B2 · Multi-component detection of gestures

Abstract

This disclosure describes techniques for recognizing gestures performed by a user, including techniques for conserving power when performing finger or hand gesture recognition operations that involve processing electromyography (EMG) data. In one example, a wearable device capable of being worn by a user comprises: a motion detector configured to detect motion of the wearable device; a tissue movement sensor configured to collect tissue movement information associated with motion of muscles or tissues beneath the user's skin; and a gesture detection module. The gesture detection module is configured to: detect motion data; enable the tissue movement sensor to collect tissue movement data; initiate a first process to determine a likelihood that a gesture occurred; initiate a second process to identify the gesture; determine, before the second process has completed, the likelihood that a gesture has occurred; and responsive to determining the likelihood, determining whether to allow the second process to continue.

Dependent claims

A device that is capable of being worn by a user, comprising processing circuitry and a plurality of tissue movement sensors, wherein the processing circuitry is configured to:

initiate a first process to determine a likelihood that a gesture occurred based on tissue movement data collected by a tissue movement sensor from among the plurality of tissue movement sensors;
initiate a second process to identify the gesture based on the tissue movement data collected by the tissue movement sensor, wherein at least a portion of the first process and the second process are performed concurrently;
determine, by the first process and before the second process has completed, the likelihood that a gesture has occurred;
and
responsive to determining the likelihood, determine whether to allow the second process to continue.

2 more elements

A non-transitory computer-readable medium comprising instructions that, when executed, cause processing circuitry of a computing system to:

initiate a first process to determine a likelihood that a gesture occurred based on tissue movement data collected by a tissue movement sensor from among a plurality of tissue movement sensors;
initiate a second process to identify the gesture based on the tissue movement data collected by the tissue movement sensor, wherein at least a portion of the first process and the second process are performed concurrently;
determine, by the first process and before the second process has completed, the likelihood that a gesture has occurred;
and
responsive to determining the likelihood, determine whether to allow the second process to continue.
