Motor cortex that controls the movements of the human body is divided functionally into each control region. In the motor cortex, the area for the hand is almost the same as the total area for arm, torso and lower body. This physiological fact indicates that human hand movements require very complicated control. As a result, our hand can perform high precision movements as an actuator. Motion capture (MoCap) technique that can digitize a position and a posture as a function of time is widely used in order to create animation and CG. It is very difficult to measure all hand movements because one hand has twenty-seven bones and nineteen joints. Therefore, it has been impossible to record the finger movements of a sports player that are high in speed and in accuracy.
