doppler
A web implementation of the SoundWave paper that detects motion using the Doppler effect with microphone and speakers.
What is doppler?
Doppler is a JavaScript library that implements motion detection using the Doppler effect in web browsers. It enables touchless interaction by emitting an inaudible tone through speakers and detecting frequency shifts caused by moving objects using the microphone. This creates possibilities for gesture-based interfaces without requiring specialized hardware.
Web developers and researchers interested in creating touchless interfaces, experimenting with alternative input methods, or exploring the capabilities of browser audio APIs for motion sensing applications.
Doppler provides a pure JavaScript implementation of academic research (Microsoft's SoundWave paper) that makes motion detection accessible using standard web technologies. Unlike camera-based solutions, it works with just microphone and speakers, offers privacy advantages, and demonstrates sophisticated signal processing in the browser.
