Path Guidance for Blind Person using Ultrasonic Sensor

Abstract

Abstract
In this paper, the proposed designed system a user-friendly system for visually disable people which helps visually impared people to detect objects in the path and show the direction for destination. Ultrasonic sensor determines the presence of object in front of the user as it finds any object, it transmits a signal to the microcontroller. It results to the output of buzzer sound. Global system for mobile application is used in the system to provide navigation to the user.
