Third Eye for Blind Using Ultrasonic Sensor

Abstract

The project offers smart gloves, a cutting-edge assistive technology solution that helps blind people navigate their environment. The Internet of Things (IoT) is used by the gloves to give environmental awareness and emergency assistance. There are almost 37 million blind people in the world, with over 15 million of them coming from India. Braille is a language used by blind or visually impaired people for reading, writing, and correspondence. When they are exploring new places, they frequently need outside help. For people who are blind, the ideal exam is to thoroughly investigate the places with minimal help beforehand. These individuals must be permitted to live safe, fulfilling lives in a free society. In this study, an ESP32-based smart glove for the visually impaired has been developed, as innovation is expanding quickly. Because the recommended smart glove can detect obstacles, it gives blind individuals more confidence when they walk in public. It has an ultrasonic sensor that can identify objects moving in front of blind people and obstacles. Additionally, it contains output devices that let people detect an object's mobility through sound, like a buzzer, vibrating motor, and LED indication. The recommended smart glove is only appropriate for blind people because it depends on them to recognise the movement of an object by listening for the buzzer's continuous beep and vibration.
