Correlation Analysis Between Tennis Swing Features and Tennis Skillfulness Using Six-Axis Sensor

In this study, we are developing a training support system that can measure swing motion and advise players. In this paper, we propose seven features for evaluating swing forms using a six-axis sensor. Also, we measured the swing motions of tennis players at various levels with a sensor mounted on the racket and extracted the features. We defined skillfulness based on control and ball speed. Then, we analyzed the correlation between the features and the skillfulness. As a result, a correlation was found between several features and the skillfulness, suggesting that utilize the features to evaluate swings.
