NAVIGATION SYSTEM PROTOTYPE FOR VISUALLY IMPAIRED USING VISIBLE LIGHT COMMUNICATION

Abstract

Wireless communication is vital for way of data communication. Due to continuous increase in the demand it’s necessary to develop alternate ways of data transfer. Authors have proposed the study of Visible light communication systems. The medium of communication is LED light signal in this method. The blinking of LED at high rates is useful for this technology. This paper is about how to use visible light communication to navigate visually impaired users. We believe that the application of visible light communication belongs to location-based services. For this application, users are able to know the information associated with a transmitter. Suppose a transmitter is present at a building, location information will be obtained and conveyed to receiver using LED light. Indoor navigation is convenient for everyone, and it is especially useful for visually impaired.
