A Research Paper on Smart Blind Stick

Abstract

Abstract: The main objective of this article is to assist blind persons who have no human needs. Notably, anytime a blind person needs help, a hand is always there for them. The blind people's safety or ability to accomplish their goals isn't always guaranteed when they utilise this stick. The person may not feel any potential obstacles in their route if they use the stick. Notably, anytime a blind person needs help, a hand is always there for them. In any case, there is no assurance that using this stick will protect persons who are blind. The person using the support of the stick doesn't sense any obstructions in their way, despite there possibly being any. Therefore, if the obstruction is too great or dangerous, the people could suffer harm. In this study, a blind stick is designed and created to aid the blind and provide them with a clear path. The system consists of an ultrasonic sensor attached to the user's stick. As the user moves the stick forward, the ultrasonic sensor and Arduino Mega mounted to the stick try to detect any impediments in their way. When the sensor detects an obstruction, the output of the receiver triggers, and the microcontroller can notice this change because the output of the receiver acts as inputs to the microcontroller. This device recognises what is in front of the user and replies by vibrating or by posing a question. After that, the person can walk around without being afraid. This device will offer the best solution for a visually impaired person's issues.
