Abstract

Approximately about 37 million people across the globe suffer from visual impairment and that more than 15 million of these are in India. The visually impaired person uses braille for the activities of reading, writing and communicating, and usually needs someone for guidance. But in this particular subject, the greatest obstacle encountered by the visually challenged people is moving from one place to another without any form of support. Recent advances in technology including IoT (Internet of Things) have brought forth modern ways of improving the lives of disabled persons. In this paper, a description of the process of designing and systematically developing the smart wearable device, an aid for people with visual impairments, is presented. The system uses ultrasonic sensors, GPS (Global Positioning System), GSM (Global System for Mobile Communication) and feedback components like buzzer and vibrator to provide information on the surroundings in real time. This wearable device assists the user in orienting and mobility by warning them through vibrations and sounds when using the device and another internal unit where the United States military coordinates cross referencing the perceptions. It is further comprised of a communication interface for a GSM module and a GPS module enabling the gadget to send current location information in times of crisis. The given device is controlled by an Arduino Uno microcontroller. It is oriented towards economy and the possibility of further development. People who are undergoing clinical trials confirm that the provided device has optimized the mobility and autonomy of visually impaired people in terms of urban planning.
