Motion Capture (also referred to as mo-cap or mocap) is the process of digitally record the movement of people. It is used in entertainment, sports, medical applications, ergonomics and robotics. In film-making and game development, it refers to recording actions of actors for animations or visual effects. A famous example of a movie with lots of motion capture technology is Avatar. When it includes full body, face and fingers or captures subtle expressions, it is also referred to as performance capture.
