IoT Based Navigation System for Visually Impaired People

The Internet of Things is playing a vital role in making human life easy and comfortable. A large proportion of the population in our society includes physically challenged people. There are several tools available to help blind people to lead a normal life, but still, most of them lack efficiency and accessibility. One of such problems is accessing public transport by blind people. This paper presents an RFID based electronic model, which will help a blind person to use public transport very quickly and safely in his daily life without any external help. The proposed system helps a visually impaired person not only in booking the public transport but also helps them to reach the bus stop through the audio guide using GPS and to pay the travel fare. The implementation of this model consists of two devices, a user module and bus module, connected through a wireless network to exchange information. The system is designed to reduce efforts and to create a comfortable life for blind people.
