Scientists are developing ways of capturing human movement in three dimensions which would allow music to be created with the gesture of an arm.

It would eliminate the need for music technicians to twiddle hundreds of knobs to achieve the perfect sound. The technique could also be used for scrolling a webpage, especially useful for people with limited mobility.
The goal of the project is to capture 3D movements using infra-red light. The light is then projected onto tiny reflective balls attached to clothing and monitored by 12 cameras. The computer recognizes the changing positions of the balls and turns different gestures into instructions for music software. read more…
