Patent ID: 8414507

Claim:
A body motion balance detection device comprising: a body motion related signal acquiring unit that acquires a body motion related signal in which a change in a body motion of a living body is detected, the body motion related signal acquiring unit acquiring the body motion related signal when the body motion related signal acquiring unit is attached to the living body; a body motion balance detection unit that detects a body motion balance from the body motion related signal acquired by the body motion related signal acquiring unit; and an output unit that performs an output based on the detected body motion balance, wherein the body motion balance detection unit is configured to execute: a foot information acquiring process for recognizing one step unit from the body motion related signal, and acquiring foot information on each respective foot of the living body, and a body motion balance detection process for detecting the body motion balance based on the foot information, and a detecting unit that determines whether the body motion related signal is indicative of walking, wherein the detection of the body motion balance by the body motion balance detection unit is executed when walking is determined, the foot information acquiring process acquires information of an odd number step and information of an even number step by separating the foot information of the odd number step and the even number step, and the body motion balance detection process detects an abnormal balance of the body motion balance by comparing the information of the odd number step and the information of the even number step.
