Abstract (in Japanese) (See Japanese page) 
(in English) Our research is aiming at real-time collision-free motion planning for character animation in virtual environments. Our system performs a fast motion planning using precomputed Dynamic Roadmaps. However, there is a problem that the processing time of motion planning is too long for real-time character animation since robust planning of various motions requires an enormous size of precomputed Dynamic Roadmaps. To solve this problem, we propose a new method using a dimensionally reduced configuration space, which includes only natural postures of a character, by analyzing principal components of a motion capture data. Our method allows fast and robust motion planning in dynamic environments. We confirm the effectiveness of our method by comparing with motion planning using the traditional probabilistic roadmaps method.
