SoundWave: Using the Doppler Effect to Sense Gestures

Date

May 5, 2012

Overview

Gestures are becoming an increasingly popular means of interacting with computers. However, it is still relatively costly to deploy robust gesture-recognition sensors in existing mobile platforms. SoundWave is a real-time sensing technique that leverages a speaker and a microphone to robustly sense in-air gestures and motion around a device. It is capable of detecting a variety of gestures, and can directly control existing applications without requiring a user to wear any special sensors.
