1P2-D08 横断歩道口に敷設した発光ブロックの視認性

Abstract

Tactile walking surface indicators (TWSIs) are necessary devices for independent walk of visually impaired person. However, if these blocks installed following guidelines for constructing TWSIs, it's unkindness to users. Therefore, we propose LED blocks installed at crosswalk entrance for blind and visually impaired persons. These blocks can be detected through the soles of shoes and through use of residual vision. This study is conducted experiment that invited amblyopic examinees. In this study, we evaluate the visibility of the LED blocks.
