Abstract

Blind people often depend on public transit for mobility. In interviews I learned that changing trains and orientation inside stations is a significant hindering reason for not being spontaneous. Since GPS-navigation typically cannot be used indoors, this paper focuses on building a tool for blind people to assist them in navigating inside train stations, designed for commodity hardware like the Apple iPhone.
