motion capture

(1) See gesture recognition.

(2) The entering of a movement pattern into the computer. For example, if a person, hooked up to sensors, goes through the act of batting a ball, that motion trail can be used to simulate a more realistic baseball player in the computer.

Capturing Live Motion in Real Time

The ULTRATRAK PRO system from Polhemus provides a series of wearable sensors that captures motion in six degrees of freedom (6DOF). The sensors connect via Ethernet, and the ULTRATRAK PRO software interfaces with 3D animation programs to provide real-time capture of the person's movements. (Image courtesy of Polhemus, Inc.)
