Relationship between Motion Features and Gracefulness

Abstract

This research focuses on ”gracefulness ” and aims to extract and model the graceful motion feature using classical dance. In the past, we have quantified gracefulness utilizing the shape of the trajectory of the fingers. However, the observer is not only looking at the hand movement but also the whole body movement. Therefore, it is necessary to expand the scope of observation to obtain multiple features closely related to gracefulness. This paper reports the relationship between head, body, and leg movements and gracefulness. This analysis showed no relation between the angle change and the impression in the time domain. But in the frequency domain, we found that the motion of low impression of gracefulness relates to the high-frequency components. And we showed the gracefulness motion is no periodicity.
