+    abstract={{This paper describes a display device for blind people using an audio-tactile process. This device allows to restitute alpha-numeric informations contained on computer video screen. The process is based on sense of touch and hearing. It combines a multicontact sensor used to find information, which is in a memory, and a speech synthesizer to translate it into sound. This display principle combines the advantages of two types of existing solutions. The display system that we have realized uses current and low cost technology.}},
