Bus Detection System for Blind People Using RFID

Abstract

This paper outlines implementation of RFID for a bus detection mechanism to help blind in travelling from one place to another. Generally, journey in a bus is a safe and comfort factor but navigation in outdoor environments is highly difficult for those who have congenital blindness or blindness from a very young age. Several solutions have been proposed like walking stick or white cane guide dogs and GPS guidelines to deal with this difficulty. Although some of them have shown to be useful in real scenarios, they involve an important deployment effort or use artifacts that are not natural for blind users. Therefore, this paper aims to develop a bus detection prototype using Radio Frequency Identification (RFID) for blind. RFID has the potential to be a useful aid with further standardization of RFID tags and improvement of current RFID readers. Interfacing reader with microcontroller (ATMEGA328-PU), using IR sensor for wireless communication design aids in improved. Radio Frequency Identification (RFID) has been an emerging technology in recent years. In the recent few years there have been a lot of advancements in the field of RFID. The application of RFID technology have been numerous and the usage of this technology has led to many application specific designs and models that are today being used in many control system. The purpose of this paper will be to develop a design and propose a plan to implement RFID technology that will help the blind people navigate in outdoor environment. This system will help us to understand and develop a prototype model which will be used as a system by people to fulfill their requirement of navigation and identification.
