Mobile terminal-based tennis instruction support system for beginners

Abstract

Visualization technologies are becoming more widely used in sports sciences. In addition to video analyses, many kinematic analyses of sports participants conducted using various sensors have been reported. The present paper proposes a method for evaluating the serve and stroke forms of tennis players by measuring ground reaction force and video analysis. In the study, we (1) perform simultaneous outdoor measurement of racket movements and ground reaction forces, (2) measure visual data feedback to an individual trainee by means of a mobile terminal from a Web server, and (3) perform a system feasibility study with the assistance of a university tennis class to evaluate the performance of the proposed system. A preliminary experiment conducted during a university tennis class has revealed the system feasibility. © 2011 Springer-Verlag.
