A SMART WALKING STICK WITH ULTRASONIC SENSOR FOR SUPPORTINGTHE VISUALLY IMPAIRED PEOPLE

Abstract

The purpose of the device is to support the visually impaired people in their day-to-day life. The module consists of walking stick connected by an ultrasonic sensor, processing unit and a buzzer supported by Arduino uno. The device supports the visually impaired people for finding out any obstacles in their path. The device consists of a pair of glasses, an obstacle detection module which includes an ultrasonic sensor, a central processing unit, an output device a buzzer and a power supply. The ultrasonic sensors identify the information of the obstacle present in front of the man and sends the output through the buzzer. The ultrasonic glasses helps the blind people to avoid obstacles. Using this blind stick, a person can walk more confidently. The smart stick will have an ultrasonic sensor to sense distance from any obstacle and a RF remote using which the blind man could remotely locate his stick.
