To clarify the motion characteristics of free-style Okinawan dance"Kachaasi", first, the subjective impression was quantitatively evaluated with semantic differential technique to cluster its types.Then, the contingency of joint rotation in shoulder, elbow and wrist joints was examined 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.As the results, in an excellent dancer, the motions of shoulder and elbow were highly synchronized and smoothly controlled. The low-frequency output of the shoulder and elbow were mutually interacted.Meanwhile, the wrist behaved independently of other joints' rotation.
