In this paper, we propose an analytical method for performing teaching, by revealing the expert’s skills. In dance, expert’s motion is smooth, but beginner’s motion is awkward. As the cause, we considered that the change of the body axis and the motion is not linked. We obtained a movement of the subject by the acceleration sensor attached to the waist. As a result, we can be classified into four patterns from the trend of acceleration waveform. Furthermore, we installed a pressure sensor in the sole of the subject, in order to clarify the differences between the four patterns. As a result, it is found that expert do weight shift by considering the next motion. This was a motion that is performed unconsciously. It was useful method to find skills, clarifying the difference by comparing the movement of beginner and expert. |
