Smart Ultra-Sonic Blind Stick

Abstract

In the Blind Worldwide, still the visually challenged persons are facing lots of problem when they are walking in their daily life. They require proper indication to detect any obstacles in front of their walking path. The followed project is designed to guide a visually challenged person to walk and avoid bumping into obstacles. Low cost ultrasonic rangefinders along with a microcontroller is used to measure the distance of any obstacles and if they are close enough provide a feedback to the user in form of beeps or vibrations. The “Ultrasonic Blind Stick†device is the best solution. The main component used for this device is the ultrasonic sensor.
