Create Motion Sensing Website Using Doppler Effect

Believe it or not, now you can use your microphone and speakers (not headphones) as a motion detection sensor that measures the Doppler effect of the sound waves using a JavaScript library called doppler.js by GitHub user Daniel Rapp. While the project is still in its infancy, the basic demo does work on Chrome! In the demo, you can try to scroll up and down the motion sensing website by moving your hand towards and away from the mic/computer. Hit the buttons below to learn more.
