The purpose of this study was to examine the correlation between subjective impressions and physical motions of shoulder, elbow and wrist in Kachaasii dance. The subjective impression was estimated with semantic differential technique, and the physical motions ware investigated with multivariate autoregressive model. The time-series data of positions and angles of three joints were calculated according to the deforming conditions and shielding directions of the ring lights. The results of cumulative power contribution and impulse response showed that mutual interaction of joint rotations produced high scores in subjective evaluation.
