Abstract
Tactile Walking Surface Indicators (TWSIs), which help visually impaired people traveling alone, could be an extra barrier for pedestrians, wheelchair users, and baby carriage users. The purpose of this study is to develop TWSIs having less heights of flat-topped elongated bars (guiding patterns) than TWSIs compliant with the Japanese Industrial Standard (JIS). This study relates particularly to indoor guidance for visually impaired people. This study examines easily detectable heights of guiding patterns and distinction between guiding patterns and warning patterns. The result indicate that the evaluation of the combination of a guiding pattern which has two bars with a height of 2mm and a warring pattern which has 20mm or 30mm in diameter with a height of 2mm is good.
