Development of walk safe cane for the rehabilitaion of blind people

Abstract

WSC will be meant for the rehabilitation of the blind people. The product is based on the distance measurement property of the ultrasonic sensors. It will measure the distance and velocity of the obstacle in the way of the person and will alarm the person about any obstacle (moving/stationary). There are ~4million blind persons across the world. Many of these persons use products similar to the WSC as travel aid for the blind. WSC will allow detection of obstacles on the ground, holes and pits, uneven surfaces, steps, and other typical obstacles in the path of the person. Apart from other similar products the WSC will also allow detection of potentially dangerous obstacles at head level. Since the device is incorporated with wireless module it will be very handy and will be much easier to use as compared to the similar products available in the market.
