dc.description.abstract In this paper we present a new system for helping visually impaired people in navigating around the campus buildings and rooms. The main idea behind the system is that it will aid the user in obtaining a more precise idea of their orientation while finding their way around the campus. The design consists of a simple Radio Frequency Identification Device (RFID) system that is based on data linking via electromagnetic waves. RFID transponders are strategically located around main entrances to each building, and also beside the entrance doors to all rooms within a building. An RFID transceiver picks up the signal that is closest to it, if any, and through the signal processing component sends it to the microcontroller. The microcontroller stores all information in a memory buffer, and plays an MP3 recording of a sound corresponding to a particular building or room number. The user is able to hear the sound through earphones. en
