Patent abstract
An audio device may be configured to detect proximity of a user hand based on analysis of audio signals captured by the audio device. For example, the audio device may be configured to perform acoustic echo cancellation based on dynamically calculated filter coefficients. The coefficients may be analyzed to determine proximity of the user hand. The proximity of the hand may be evaluated over time to detect user hand gestures.
