Barrier Detection Glasses for Visually Impaired People

A simple, physically based analysis illustrates the detection of front-end objects. Notification tools which are buzzers and disk vibrators are used for barrier detection. The project involves wave transmission and reflection of transverse waves. The receiver takes an input in the form of a transverse wave and conversion takes place to get the output as a longitudinal wave. The output device and barrier detector module are connected to a processing unit which is an ultrasonic sensor. The code is inserted to guide the visually impaired person who cannot hear by the proximity sensor, and it always keeps a track of the front view. Such a tool is a system that uses ultrasonic sensors to identify obstacles. It can help visually impaired individuals to navigate their surroundings safely, increase their mobility, and improve their overall quality of life. The tool provides feedback through audio and a vibrator.
