The V Motion Project is an interactive music and video performance system that translates a performer’s gestures to music and motion graphics using Xbox 360's Kinect motion sensor. The performer’s movements are captured by two Kinect motion sensors and projected on stage in the form of a computer generated avatar. The music system works by connecting the Kinect to Ableton Live, a music sequencing software used by Djs and musicians during live performances, so when the performer hits certain hot spots, different music samples and notes are played. Below is a video showing the full device in action. Very very cool.....
