Abstract

The purpose of this study was to extract the motion characteristics that are closely related to the subjective evaluation of hip hop dance performance. The subjects were 11 expert, six non-expert and nine novice hip hop dancers. Each dancer performed the “wave“ motion as the experimental task. Movements of upper extremities during the task were captured by a motion capture system and several kinematic parameters including the propagation velocity of the wave (PV) were calculated. We found that the coefficient of variance of the PV was highly correlated with the subjective evaluation by the judges (r=0.770, p<0.01). This result indicated that smooth propagation of the wave was most closely related to the subjective evaluation to the wave performance.
