Rapid Response Smart Blind Stick With Obstacle Detection Using Arduino

Abstract

The smart blind stick helps visually impaired people to commute and to do their work easily. The usual blind stick doesn’t detect the obstacle in the way of visually impaired person and hence sometimes becomes a cause of fatal road accidents. Because the visually impaired person does not know what type of objects is in front of them, the person cannot recognize the obstacle and how far is he/she from the object which makes the commuting process of the blind person strenuous. This paper presents the blind stick works with the help of ultrasonic sensors and Arduino for visually impaired people. With the help of smart blind stick, the object is detected using an ultrasonic sensor and the person helping the blind person. GPS is integrated with smart blind stick for real-time tracking of the blind person which can be very useful in case of any casualty.
