Discussion about Correlation of Walking and Psychosomatic State by Using Motion Image

Abstract

It is said that the physical and mental state is reflected on the walking motion well. The walking motion shows the psychosomatic state in other words. The purpose of this study is to consider correlation of walking motion and the psychosomatic state. The walking motion is defined by the fixed point observation of the legs using the motion image of front view. The Measuring points are four points in all, which are both knees and both tiptoes. The features of the walking motion was extracted from time series data of the length between measuring points which was measured from the motion images. Principal component analysis was conducted with those charecteristics. Then multiple linear regression analysis was also conducted with principal component scores. As a result, psychosmatic state of each subject was estimated by walking movement.
