Abstract

The invention refers to a tennis swing analyzing device which is used for knocking down a ground ball, intercepting or serving a ball. The swing analyzing apparatus includes: a three-axis acceleration sensor attached to a tennis racket including a handle and a head, for measuring accelerations in the directions of three axes when a swing for hitting a tennis ball is taken with the tennis racket; a three-axis gyro sensor attached to the tennis racket, for measuring angular speeds about the three axes when a swing for hitting a tennis ball is taken; and an analyzing device. The analyzing device has a receiving function to receive data regarding the accelerations and the angular speeds from the three-axis acceleration sensor and the three-axis gyro sensor; a coordinate axis conversion function to convert relative coordinate axes that are the three axes for the accelerations into absolute coordinate axes on the basis of the angular speeds; and a calculation function to calculate an index of the swing on the basis of accelerations resulting from the coordinate axis conversion.

Description

technical field [0001] The present invention relates to an analysis device and analysis method for analyzing the swing motion of a tennis racket performed by a user. Background technique [0002] The tennis swing is different for every player. The swing is influenced by the specifications of the tennis racquet. For example, if a racket with a low rebound coefficient is used to hit a ball at high speed, the player will start to exert force. On the other hand, when using a racket with a high rebound coefficient to control the speed of the shot, the player's hand will loosen. The cooperation between the golfer and the racket is very important. Proper swing analysis enables the correct fit. Proper swing analysis helps to improve a golfer's skills. [0003] Swing analysis also contributes to the research and development of tennis rackets. Furthermore, the swing analysis also helps to promote racket sales. [0004] Patent Document 1 discloses a swing speed measurement metho...
