Patent number: 6798414Abstract: A base animation storing unit stores base animation, generated for each grid point in a range of adaptation with regard to a certain motion. A synthesizing unit starts adaptation motion synthesizing in the event that an end effector exists within the range of adaptation. The synthesizing unit calculates a weight array based on the position of a target and the position of each grid point, and adds base animation with the calculation results as linear addition coefficients, thereby generating the desired animation. Accordingly, animation cooperatively display with multiple objects of display can be effectively generated.Type: GrantFiled: December 7, 2001Date of Patent: September 28, 2004Assignee: Sony CorporationInventors: Yasunori Ohto, Yuichi Ueda, Takashi Nozaki, Yoichiro Serita
