Scope of Manipulability Sharing: A Case Study for Sports Training

Abstract

Recently, advanced information communication technology and robotic technology have been used for developing a sports-like game application and low-cost interface devices, such as wii-sports, to encourage performing exercises in a room. Such an application can provide an easy-to-understand visual feedback for players by using a virtual reality head-mount display. However, those do not provide quantitative information about the body forms required for training during sports to improve the performance and skill of players. The purpose of this study is to develop an intelligent scope of manipulability sharing considering the dynamic change in the human body form (structure) in sports motion, thus providing an evaluation result based on the manipulability theory for both the player and the instructor in real time. Evaluation tests using a prototype system using a smart glasses and a Kinect sensor are conducted to verify the effectiveness of the proposed scope of manipulability sharing in pitching and batting motions.
