Abstract
System of quantitative feedback to novice is required in the medical, welfare and sports field. In the field of these, inexperienced user can be obtained in technology lore to observe and mimic the model of the expert who has mastered the dexterity. However, in order to gain experience over a period of time, it takes time to have training of successors. So, we focused on the sports field. In this paper, we have built a free throw shot measurement system using the motion capture system, and validate "skillfulness". Next, we have considered quantitatively the shoot success. Then, we confirmed that the motion transmission is occurring to the skilled person. However, motion transmission showed that does not necessarily depend on the shoot success or failure. Finally, we found that force transmission using motion transmission made success.
