Abstract
Many of people with low vision walk using their low sight ability. They have difficulties to walk especially at night. In this research, we propose the guidance system with LED lighting, in order to make people with low vision easy to walk at night. First of all, the questionnaire was performed in order to clarify night walk of people with low vision. Many of them walk daytime using residual eyesight. They, however, can't use residual eyesight at night. Therefore they need guide and reduce going out at night. Secondly, we perform laboratory experiments by low vision subjects in order to verify effectiveness of the proposed system. As a result, the system is effective for those who walk under low illumination (6 lx or less). In addition we verify the suitable combinations of the installation interval and brightness of spots. "5 m interval and 90 lx brightness" and "7.5 m interval and 180 lx brightness" are efficient for the guidance of them.
