Abstract

In this paper, we propose a device that indicates the direction of an obstacle that is encroaching into the path of a visually impaired person who is walking. Our proposed system, which would resemble a pair of eyeglasses, first detects an obstacle and then indicates its direction and distance to the wearer through puff of air to the forehead. This paper describes the preliminary testing for presenting distance information.
