Relationship between Human Body and Tools from Viewpoint of Physical Changes

Abstract

This paper examines the relationship between tools and the human body, and we discuss an ideal method of design from the viewpoint of physical changes of human body. It has been necessary to reduce the housework load by using household appliances, the use of which should not require any particular skill. However, in former times, we use different types of housework equipment, which did require skill to use. And a body changes as to use equipment. Like that, a phenomenon to appear subsidiary, for example, a physical skill is succeed, and users image is appeared. The perceptual system of humans body is rearranged by a relation with the environment, and physical ability improves through managing tools. The ideal relationship between a piece of equipment and the human body is not only to externalize but internalize the function of the equipment.
