Locomotion Assistance for the Blind

Abstract

We have developed a triangulating laser telemeter adapted to the space perception for the blind: the “Teletact.” Two parts compose the Teletact. The first part is a laser telemeter, which detects the distances to obstacles, and the second one is an interface, which presents these distances to the blind user. The Teletact was developed originally with a sonorous interface. Due to the long time training required by this interface we have tested some new interfaces based on other modalities (tactile and force feedback). In this chapter, we present all these interfaces and discuss them.
