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 an auditive interface. Due to the long time training required by this interface we have tested some new interfaces based on other modalities (tactile and force feed-back). In this paper, we present all these interfaces and discuss them.
