Abstract: The major challenge to any visually impaired person is to identify and avoid obstacles and to adapt themselves to the surrounding environment. Some of the conventional methods used by the visually impaired/challenged people to reach their destination are talking sign, guide cans, echolocations etc. In this paper, we have discussed some of the existing systems in this domain and we have proposed a novel idea that can be implemented with the help of wireless sensor networks (WSN) for easy navigation of visually impaired through public transport.
