Transforming Any Flat Surface Into a Control Panel With Sound

New submitter brunozamborlin writes "I just published a short video that shows how a very cheap contact microphone can be used to recognize different types of fingers touch and transform any surface into an interactive board. In the video we put the microphone over different surfaces such as kitchen tables and balloons and through realtime gesture recognition we show how we can play different virtual music instruments using a technique called physical modeling . A mobile version would be definitely possible." The project's Web page shows several more examples. Update: 12/31 15:17 GMT by T : Bruno Zamborlin points out that the surfaces don't need to be flat; instead, they simply need to be rigid.

Re:Training?

Yes you can train the system with your own gestures :-)

I see, its a less useful version of this

saw stuff like this years ago. cant find the exact tech demo that i originally saw that used 3 mics for triangulation, but this video is pretty close. even mocked up a rough version (low precision, slow response time, but pretty damn good for an afternoon worth of work and very little experience with arduino) tied to a projector in my shop. customers had a blast with it, thought it was the coolest thing in the world. http://www.youtube.com/watch?v=CxDHiwheK8w&feature=related
