Smart Lightweight Wearable Device for Partially Impaired and Blind People

Abstract

Being able to live independently is everyone’s goal but there are many people among us who are incapable to live independently just because they are not gifted with the senses a normal person has. This paper outlines state-of-the-art solution that enables the blind person to perceive the world in a way very much similar to a normal person, by enhancing the effectiveness of the senses they have, with the aid of technology, to sense the surroundings and to make sudden reflexes. Conventional white canes simply detect obstacles at a certain distance with the help of ultrasonic sensors, but do not give information about the type of situational surrounding they are in or how to counter sudden unexpected obstacles. Our state-of-the-art proposed system works on Arduino Nano which in turn consists of various sub-modules including Ultrasonic Sensor, Vibration Motor, Buzzer, Wi-Fi Module, Linode Cloud. A simple, cost-effective, configurable, easy to handle to device. This device will be effective, efficient, and unique in its capability in specifying the source and the distance of the obstacles that may encounter the partially impaired and blind people. By wearing this device, blind people can full avoid the use of blind stick (white cane) and such other tools. This device will help the blind people to navigate without holding a blind stick that makes more convenient.
