手指障害者のための非接触型入力インターフェースの開発

抄録

A noncontact input interface using image processing for people with disabilities of the fingers, such as rheumatism, collagen disease, and osteoarthritis, has been developed. The input interface is simply composed of a CCD camera and PC. Taken with the CCD camera, the fingers were appropriately detected using image processing in this paper. An on-screen keyboard and control box were also made. In order to evaluate a performance of the input interface, three healthy subjects input some example sentences using it. From the experimental results, it was clear that the beginners could directly input them in Microsoft Word without any difficulty, and the input characteristics with the least error were experimentally shown in this paper.
