An IoT based Voice Controlled Blind Stick to Guide Blind People
share
Visually impaired people find it difficult to identify objects in front of them while walking down the street, which makes it risky. The smart stick comes as a way to define the world around them. In this paper, we propose a solution, presented in a smart stick with an infrared sensor to detect staircases and a pair of ultrasonic sensors in order to detect any other obstacles in front of the user, within four meters. Furthermore, another sensor is placed at the bottom of the stick to prevent puddles. Speech warning message is triggered upon identification of any obstacle. About 39 million people are permanently blind and about 285 billion are visually impaired. Blind person, who doesn't walk alone, struggles to do his own job. There's always fear of getting injured and getting into an accident. How can we solve those problems? Indeed, this paper has provided a solution which can relieve the blind from this problem. Which is" Blind Stand with voice control to guide blind people" This is essentially a device consisting of Arduino UNO, Ultrasonic Sensor and Voice Module that informs and notifies the blind person of the hazards This will help a blind person to walk comfortably and keep themselves safe from danger.
