Abstract
The falling of the elderly person is a serious social problem. The decline of the balance ability is one of the big factors of the fall. The development of the balance ability training system is of aim of this study. In order to improve the effect of training, we suggest a balance training system specialized in somatic sensation by intercepting human subject's sight. This paper presents an investigation about superiority of the sight interception training. Specifically, eye-open training and sight interception training are compared by the foot pressure center trace before and after the training. As a result, the sight interception training was significantly shown to be effective. This result will be applied to the development of the balance ability training system.
