Motion analysis method, motion analysis display method, and motion analysis device

摘要

A motion analysis device has a determination unit which uses an output from an inertial sensor mounted on at least one of a subject and a tool operated by the subject, to determine a dominant hand of the subject in a swing. The determination unit can determine the dominant hand on the basis of the sign of angular velocity or acceleration from the inertial sensor. A calculation unit which calculates motion analysis information in a swing, using an output from the inertial sensor can add dominant hand information from the determination unit to the motion analysis information. The motion analysis device can include a coincidence determination unit which determines that a first subject and a second subject have different dominant hands, and an inverted image generation unit which inverts first motion analysis information in the case of no coincidence.
