Using motion capture for interactive motion editing

Motion capture technology has been widely used for creating character motions. Motion editing is usually also required to adjust captured motions. Because character poses which include joint rotations, body positions, and orientations are high-dimensional data, it is difficult to manipulate character poses through a conventional mouse-based interface. We propose a motion editing system that uses a motion capture device. Our system can capture a motion and edit the captured motion using the same motion capture device. Our motion-capture-based interface can specify motion editing parameters such as time period, body part selection, end-effector position, pose, and motion segment. We conducted a user study to compare our system and conventional mouse-based motion editing system. The results showed that our interface is more efficient than the conventional interface.
