Parallel visual data acquisition is not available to blind. Yet, sequential tactile scanning (e.g. white cane) allows them to form mental concepts of their surroundings, albeit slower. The purpose of this project is to demonstrate that acoustic serial scanning of graphical objects allows a blind user to form mental concepts and to reproduce these objects graphically. Moreover, this system is designed to enable blind users to obtain graphic information and express their visual ideas graphically through sound.
