Education system of skill succession based on 3D evaluation and improvement in time series

Abstract

This paper presents an educational support system of skill succession with body motion based on 3D (three-dimensional) biomechanics evaluation. Skill succession using body motion seems different because human cannot attain the perfect copy or imitation of the reference skill motion. We call it the imperfect imitation problem. Then, we propose the 3D skeleton motion viewer and e-learning education system. The learner cannot move the expert motion, however, watching only 3D skeleton motion movie. So, our system supports learner using the judgment of the expert instructors (teacher). In experiment, to evaluate the effectiveness of the proposed system, some education of sports such as swimming, darts game and karate are adopted. The evaluation is a learner's improvement and teacher's satisfaction from the interview.
