摘要:
A telemeter hold by the hand of a blind person measures the distance to the obstacle encountered by its laser beam (1 mW at 670 mn). A microprocessor realises a correspondance between the distance and a musical note sent to an auricular. The blind person directs the beam thanks to his proprioception. The most important information is not the absolute distance but the musical melody correponding to the profile of the environnement. Combining musical perception and propioception the blind acquires the form of the obstacles and his position relative to them. Method of learning is in progress.
