Abstract: In This Paper, an Indoor navigation system is proposed for persons with visually disability that utilize VLC (Visible Light Communication) Technology. Using VLC we can provide precise locational coordinates or directions regarding their journey. Light Fidelity (Li-Fi) refers to the VLC technology. VLC is based on the concept that uses visible light as a means of communication enabling faster flow of information [1]. The principle of VLC is that it uses light as a medium to deliver high speed communication. The main idea is to create internal navigation system for the area to create automatic navigation for the visitor who are visually challenged. The Li-Fi is preferred over Wi-Fi because Wi-Fi is nothing but radio-telecommunication which effective within premises, while Li-Fi is effective for faster communication in restricted places without any hurdles. The concept of Li-Fi is used to give the navigation path for visually challenged person and particularly voice guidance of the walk way. Headphone is used to give the voice message to such people. The data is transmitted through the LED light which emits the visible light and an embedded system accepts from receiver. The received data is converted into audio format for the blind people. The suitability of system has been confirmed by means of useful prototype through a trail with blind person.
