The major challenge of visually impaired person is in mobility, object identification and identification of space around him/her. The proposed RF Based Talking Signage for Blind Navigation aims to provide a universal electronic travel guide for the visually challenged people. This system incorporates a user friendly and versatile method called “Talking Signage” that is implemented using android devices. The system uses an Android application in the mobile phone which could deliver voice messages about the user environment via a heterogeneous network. It can be deployed in any dense environment so that blind persons can fulfill their needs. The primary advantage of the system compared to other system in the area islow cost, ease of transport, less power consumption, lightweight, and it could be utilized by those peoples who are technically challenged. The architecture proposed in this paper clearly shows communication between a mobile phone and a heterogeneous network enabled with RF devices. We have implemented the system in our university environment and the proposed system found to be a great success.
