Abstract

In this paper, a man-machine interface included in an integrated environment that improves the mobility of blind persons into a limited area is presented. The proposed solution relies on the Acoustic Virtual Reality (AVR) concept, which can be considered as a substitute for the lost sight of blind and visually impaired individuals. According to the AVR concept, the presence of obstacles in the surrounding environment and the path to the target will be signalized to the subject by burst of sounds, whose virtual source position suggests the position of the real obstacles and the direction of movement, respectively. After a brief presentation of the AVR concept, the paper is focused on the implementation of the proposed man-machine interface, based on this new concept and the status of the research. Finally, some conclusions and further developments are also presented.
