Demonstration of Pedestrian Movement Support System Using Visible Light Communication

We constructed a pedestrian support system for the visually impaired that uses visible light communication (VLC) from self-illuminating bollards. To achieve this goal, we conducted a visibility evaluation using pedestrians with low and normal vision to determine the best bollard lighting pattern for pedestrian navigation systems. Furthermore, we designed a receiving terminal that is easy to manage and can be operated by touch alone. Moreover, we constructed a sidewalk model to evaluate the navigation system, and the communication area of the system was experimentally determined. We then created a prototype of the navigation system using VLC. The prototype was evaluated by visually impaired users, clarifying the effectiveness of the system.
