Detecting User Gestures With A Personal Mobile Communication Device

Abstract

System and methods for recognizing user gestures by processing audio from a microphone in a personal mobile communication device (PMCD) are disclosed. One such method includes sensing audio using a microphone in the PMCD and detecting a user gesture from audio sensed by the microphone. One such system includes a microphone, memory for storing instructions, and a processor configured by the instructions to sense audio using the microphone and detecting user gestures from audio sensed by the microphone. Also disclosed is a computer-readable medium storing a computer program for use in a personal mobile communication device. The program comprises instructions to: sense audio using a microphone in the personal mobile communication device; record the audio sensed by the microphone; process the recorded audio to extract a feature; classify the feature of the recorded audio; and identify one of a plurality of user gesture types based on the classified feature.
