Researchers at the University of Dundee have used the Xbox 360 Kinect sensor to control optical tweezers, a set of laser beams used to manipulate particles.
Physicists control the particles through their body movements, which are read by a Kinect-based interface called "HoloHands." While not completely perfect yet, with a latency issue and the occasional misinterpration of the user's movements, the interface has been quite successfully tested moving silica particles.
