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

A motion analysis display method for displaying a motion analysis on a first subject and a second subject as subjects, the method comprising:

• calculating first motion analysis information of the first subject and second motion analysis information of the second subject in a swing, using an output from an inertial sensor mounted on at least one of the subject and a tool operated by the subject;
• determining a dominant hand of the first subject and the second subject, using the first motion analysis information and the second motion analysis information;
• inverting the positive and negative of an output of the first motion analysis information if, as a result of the determination, it is determined that the first subject and the second subject have different dominant hands;
• and
• displaying, on a screen, an image based on the first motion analysis information that is inverted.
