Abstract:
Baseball and softball are popular sports worldwide. In baseball/softball, batting is a fundamental action, but it is also one of the most difficult skills to master. Batting requires constant practice and proper guidance. Experienced coaches can provide instant diagnoses and feedbacks tailored for individual players. In the absence of such coaches, tools such as motion tracking systems or sports bracelets may help to assist the players. Unfortunately, they are either too expensive and awkward to use, or too limited in providing useful diagnosis and guidance. In this paper, we introduce a low-cost diagnosis and guidance tool for batting training in baseball/softball. The tool requires only one wearable device and one camera, such as the one on the smartphone, to capture the player's motion. The collected data are summarized and analyzed to derive the distinct features of the player's actions in different swing stages. The tool then pinpoints the mistakes and discrepancies in player's batting actions by comparing with expert actions, which in turn guides the player to perfect the action. Evaluations on real users show the effectiveness of our tool in comparison with experienced coaches.
