Dynamic lighting sign system for way-finding by people with low vision

金沢大学大学院自然科学研究科情報システムWe developed and proposed a dynamic lighting sign (DLS for short) system for people with poor vision to use to find their way. The DLS system uses a chain of lighting units with LED to indicate the way and is controlled by means of a PC. We implemented the DLS system for helping people to find their way and evaluated it in terms of light-flashing time, spatial interval and colour. We also carried out an experiment to evaluate its effectiveness in helping people find their way. © Springer-Verlag 2004
