Abstract
The purpose of this study is to examine the relationship between physical motion characteristics and the subjective impressions produced in dancing. The structure of subjective impressions for dance motions with no regular rule of operation was investigated using Okinawan folk dance "Kachaasii". Only the movement of the leg was discussed here. First, the questionnaire method and the principal component analysis were adopted for investigation of the mental structure of the leg motion in dance. Next, the dance was reproduced with computer graphics, and the subjective impressions were examined. The results showed that the movement of leg has five subjective scales : preference, weight, width and kinetics.
