Abstract
Navigating the visually impaired people are challenging in the unfamiliar environment. This paper proposes a system for the impaired people to guide them towards a destination in the unfamiliar environment. The proposed system at first informs the way to destination then guides towards the destination by making different sound informing different things in the environment. Following the sound, the impaired people know the characteristics of the environment and predicts the position of the things and moves towards the destination. This system design by using Bluetooth wireless network to accomplish the navigation. Two types of module are used namely receiver module and transmitter module. Receiver modules are located on different things in the environment. The impaired people carry the transmitter module in his/her hand and transmits a signal by pressing a button. During the movement of the impaired people the nearby receiver modules receive the transmitter signal and make sound informing the location and nature of the things. The study shows that the proposed system is useful in navigating the visually impaired people.
