Movies, animation films, and games are universal cultural items that can easily attract many people with their impressive visual arts technologies. The main characters of these cultural phenomena carry out various motions according to their own purposes in a virtual environment, and the motions are usually created by keyframing and motion capturing. How to create character motions has been one of the most important issues which the researchers in graphics fields have focused on. Since many time-consuming problems related to keyframing and motion capturing create intense labor in a work environment, advanced technologies need to be developed to establish an automated production system. Also the developed technologies should be intuitive for animators to use to promote increased efficiency in the animating process. In this paper, we discuss physics-based character motion research which can modify the limitations of keyframing and motion capturing.
