Abstract
Transport mobility appears to be closely linked to a person's well-being, especially for elderly people. The development of specialized transport devices to compensate for the decline in mobility of the elderly is important so that they may move around and lead an independent life as they wish. Mobility devices such as electric carts offer great utility for transport; however, the electric cart has yet to gain popularity in the open market. Thus, it is necessary to examine ways of expanding the usage of such devices and to clarify their effects on improving the quality of life of the elderly. Here, we investigate the change in the quality of life from the viewpoint of health and welfare with the use of personal mobility mode, in the daily life of the elderly using various types of evaluation measurements.
