Using Lights to Aid in the Movement of People with Low Vision(<Special Issue>Lighting Technology Supporting Social Welfare)

Abstract

People with low vision walk with their remaining visual capability, and because their eyesight declines prominently during the night time, many walk using streetlights as a guide. Thus, it is effective to deploy streetlights systematically. However, it is difficult to visually indicate changes in walking environment such as staircases or crosswalks. In this research, we discuss how blocks for guiding the visually-impaired can be visually enhanced using LED illuminations to assist movement in such environmental changes.
