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

在本文中，我们开发和评估的可见光通信（VLC）系统的视觉残疾人的运动辅助信号交叉口或在地铁站，通过使用大量的调查结果。首先，通过对被试的行为分析，发现交通灯檐、VLC接收器和用户练习方法的改进提高了引导精度。其次，对地铁站厅视觉残疾人运动辅助的新型VLC系统进行了开发和分析。

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.
