Digikeys

Digikeys turns any desk into a playable instrument using just a laptop's webcam and microphone. I'm a college student who gets the urge to play simple music, but a dorm has no room for a piano. With Digikeys, you point the camera at your desk, say what you want ("two octave piano", "drum set"), and tap the desk to play. Objects on the desk become instruments too: a ceramic mug becomes a bell, a phone a hi-hat. Taps are detected by fusing the mic (when) with webcam hand tracking (which finger, where), so sound plays about 60 ms after contact, with two-hand chords. No instrument to buy and no needed hardware.
