Design and development of blind navigation system using GSM and RFID technology

Abstract

Objectives: The main objective of this work is to provide a cost effective way to allow path planning for blind people. Methods: The Blind Audio guidance system hopes to allow the visually impaired users to simply press a button, speak the desired destination to the Blind customer care, and be guided there with the use of audio instructions. The system provides a portable unit that can be easily carried out and operated by a visually impaired user. To implement a wrong path identification alert system for Blind and to provide blind to communicate with the customer care in a finger Tip. In this work ultrasonic and RFID are combined to navigate the blind. Findings: The tool provides information about the direct surroundings of the blind to allow him to move around without collisions. The Obstacles around the blind person up to a certain distance can be understand by a system using a sensors. Applications/Improvements:.
