Recording Kinect-Based Choreography

The motivation for our project is to provide choreographers with a new software and hardware tool for composing and recording multi-dancer choreographies from a single dancer. We use a Microsoft Kinect camera/sensor to record 3D point-cloud sequences of a dancer in motion. In a 3D point-cloud, or sequence, a grid of 640x480 infrared dots are projected by the Kinect sensor, and a sensor records the position of these points in space and the (x, y, z) coordinates of each point are computed and recorded 30 times a second in a movie. The body of a dancer intersecting with the projected infrared dots create a 3D moving in space. When viewing this human surface on the computer, the viewing point can be chosen to be different from the point where the original kinect stood during the recording.
