MOTION ANALYSIS DEVICE, MOTION ANALYSIS SYSTEM, MOTION ANALYSIS METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a motion analysis device for evaluating a swing propriety more easily than the prior art.SOLUTION: A motion analysis device for using the output of an inertial sensor, comprises: a first specification part for specifying a first axis along the longitudinal direction of a shaft part of a locomotorium tool in the address position of a user; a second specification part for specifying a second axis forming a predetermined angle with respect to the first axis, by using a ball hitting direction as a rotation axis; and an adjustment part for adjusting the angle of the second axis in the case where the angle of the second axis exceeds a threshold angle.SELECTED DRAWING: Figure 1
