The effect of Kansei information on human motion - basic model of Kansei and analysis of human motion in violin playing

The purpose of this study is to derive evaluation functions to plan human motion involving Kansei effect. Clarifying the effects of Kansei on human motion has contribution to the design of human-machine interface and robot planning. This study deals with violin playing as an example of human motion affected by Kansei. In this paper, a basic model of violinist´s playing information flow and results of experiments which were carried out from the basic model are described. In the experiments, scales were played by three professional violinists to estimate the effects of Kansei information. As a result, the following rule has been derived: when the Kansei information changes, both the bow force and sounding point also change, but the bow speed does not change
