観客視点を考慮した古典舞踊動作における手先軌道の解析

抄録

As robots in the welfare and service industries must come into contact with humans, they are required to make favorable impressions on human sensibilities. Our research focuses on the concept of “graceful motion,” as defined by William Hogarth, who was an English painter and an aesthetician. To quantify the gracefulness of human motion, we approximate hand trajectories of five classical dancers by the B-spline curve. Then, we extract the S-shaped curves from these approximated trajectories and analyze its curve shape on the plane considering the audience's viewpoint. Finally, the relationship between the result of analysis and the impression evaluation is discussed.
