The invention concerns a method and a system enabling the blind and the partially sighted to direct themselves and find their way in unknown surroundings. Said method consists in teletraining using a portable sensor in particular touch-sensitive or audio, the blind or partially sighted person about the path he must follow to move from one point to another, avoiding obstacles. Said method enables the blind or partially sighted person, having no material landmark which he could remember and recognize by feeling his way with his walking stick, to find his way particularly in streets of a town, in the corridors of an underground railway or of a building.
