Development of a Motion Visualization System with the Center of Gravity for Novice Learners

Abstract

To control the center of gravity of the body is one of the most important issues in motor skill learning, however, it is difficult for us to imagine the center of gravity, because he/she cannot see it. Furthermore, when he/she learns motor skill by coach or reference book, the center of gravity is often described with ambiguous expression, therefore, he/she find it difficult to know the center of gravity. In this background, we developed a motion visualization system with the center of gravity for novice learners The learner's motion data is got by wearable motion capture system with gyroscope. By using this system, a learner would be able to visually understand the relationship between his/her body movement and the center of gravity.
