Bus Detection System for Blind Using Rfid with Prototypes for the Bus Stop and For the Bus

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 with two prototypes one at the bus stop and the other one inside the bus.The key components for these prototypes are voice ic and two zigbee units along withtwo switches for accepting and rejecting a bus request.
