3D MOTION CAPTURE LABORATORY

Currently I am supervising the 3D Motion Capture Laboratory. The 3D Motion Capture Laboratory provides the state of the art technology for recording human movement in 3D. It is equipped with an optical motion capture system to support the real-time capture of 3D human motions. This technology has been adopted in applications such as animation and movie production.
