# Using Sound Waves to Sense Motion – Controls Devices

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.
