Abstract
A body motion measurement device capable of detecting a body motion balance without installing a pressure sensor is provided. The body motion measurement device includes an acceleration detection unit for detecting a change in acceleration by walking, a calculation unit for detecting a walking balance from the acceleration signal detected by the acceleration detection unit, and a display unit for performing an output based on the detected walking balance. The calculation unit for detecting the walking balance executes step and step of recognizing one step unit of walking from the acceleration signal and acquiring PPodd, PPeven, Todd, and Teven, which are the foot information, and steps of detecting the walking balance based on the foot information.
