視覚障害者の歩行誘導のための頭部回旋装置の開発

抄録

In this paper, we developed a head-rotation device for walking guidance of the visually impaired. This device utilizes the characteristic that the direction of walking changes to follow that of the head. Previous studies have confirmed that the walking direction can be controlled by giving the head a forced gyration motion. In this study, we introduced a pressure sensor to detect the user's intention of head rotation, and improved the system to allow free head rotation. By doing so, we confirmed that a more natural and reliable walking guidance can be achieved by linking the control that allows free head movement with the forced rotation movement.
