Abstract
Walking environment for visually handicapped people has improved. However, the present condition of pedestrian spaces still causes difficulty for them. A good sample is a spiral ramp. In this study, we put yellow-colored braille blocks on a spiral ramp, and surveyed the spatial cognition of visually handicapped people to improve the ramp. To clarify the characteristics of spatial cognition and search behavior, experiments were performed using 32 different courses. Subjects were visually handicapped people and eye-masked people with ordinary vision. The search behavior of the two groups was compared and analyzed by walking locus and observation; and the spatial cognition, by interview and observation.
