Abstract :
This paper addresses a 3D world perception principle and their usage for cognitive map building by visually impaired people. These bases are applied to define a new electronic travel aid named intelligent glasses system (IGS), a wearable system. IGS provides to blind people an information on their nearest 3D environment structure, and especially a tactile stimulating cognitive map of the obstacles located in user´s peri-personal space. This paper outlines briefly the IG system, and presents first results on the validation of the proposed representation via psycho-physiological experiments.
