Abstract

In this paper, we propose a method for generating CG animation of natural hand motion in playing a piano from score data as input. This method employs inverse kinematics and key-frame technique to generate the animation. To achieve this purpose, we analyze actual piano-playing motion and extract the common features. We propose to calculate natural key poses by using a weighted pseudo inverse matrix and the canonical pose (pose in the rest) in the inverse kinematics. We also propose to use pre-keying motions as the key frames. We evaluate the generated piano-playing CG animation using the pair comparison method and verify its naturalness.
