Walking movement analysis for visually disabled and evaluation of the guidance system using visible light communication technology

本文利用大量的调查结果，对视障人士在信号交叉口或地铁站台辅助行动的可见光通信系统进行了研究和评价。首先，通过对受试者的行为分析，发现通过对红绿灯檐、VLC接收器和使用者练习方法的改进，提高了诱导精度。其次，对新型视障人士地铁站台运动辅助VLC系统进行了开发分析。

In this paper, we developed and evaluated the visible light communication (VLC) systems for the visually disabled persons' movement assist at signalized intersection or at subway concourse by using the result of many surveys. First, it is found that the guidance accuracy was advanced by improvements Dn the eaves of traffic light, VLC receiver and practice method for users through behavior analysis on subjects. Second, it was developed and analyzed on new VLC system for the visually disabled persons' movement support at subway concourse.
