An investigation of a model for the generation of "the intended random action" Miki Goan （Visiting Researcher,ATR Media Information Science Laboratories） URL；http://www.kmu-f.jp/miki/research.htm This study presents a model of motion generation based on ecological psychology, which emphasizes a cycle of perception and action. The model proposed here deals with the generation of "the intended random action." It is intended to improve the realization of the movements of a CG character. The idea of "the intended random action" has been derived from a study of dramas directed by Oriza Hirata, who works with the perception of reality. In this study, actors’ actions are captured by motion analysis system and a fine motion model is constructed.
