MOTION ANALYSIS METHOD AND MOTION ANALYSIS DEVICE
First Claim
Patent Images
1. A motion analysis method comprising:
- calculating, with the use of an output from a first inertial sensor installed above a sporting gear, to specify a first imaginary plane formed by a first line segment representing a direction in which a shaft part of the sporting gear in a static posture extends and a second line segment representing a ball hitting direction.

Abstract
A motion analysis device includes a calculation unit which specifies a first imaginary plane, that is, a shaft plane formed by a first line segment representing a direction in which a shaft part of a sporting gear in a static posture extends and a second line segment representing a ball hitting direction, with the use of an output from an inertial sensor.
