An avatar motion system for realizing gesture functions

In recent years, various communication robots have been developed, and humanoid robots, such as androids, offer the particular advantage of high expressiveness in communication through facial expressions and gestures. On the other hand, previous research has pointed out that using such teleoperated highly flexible robots can lead to complex control methods. Therefore, in this study, we developed an automatic motion system for an avatar based on the operator's speech for asynchronous presentations. This study aimed to comprehensively cover the functions of gestures based on sociology. The effects of key modules were also experimentally verified, and demonstrated the effectiveness of the implemented functions. The main contribution of this study lies in demonstrating how each of these gesture functions can be realized and clarifying the impressions they convey to the participants.
