If you haven't been following his work, Chris Vic is doing some really amazing stuff with his Kinectar Performance Platform. This latest video shows what can be achieved when Kinectar is used in tandem with live performance art. The end result is an immersive experience that seamlessly mixes live motion with musical accompaniment that is generated by the performers actual motion.
The Pulse project was designed to engage audiences by combining musical accompaniment that directly translates motion being captured by the Kinect sensor. The entire application was developed in house and required the development of their own language (Pulse SL) in order to achieve a clean, small footprint that sends notes or controller events to music software such as Ableton Live.
