A Bluetooth Based Local Positioning System
In this paper we present a new system for aiding blind students in finding their way around a university campus. The main idea is to use Bluetooth transmitters to indicate the current location of the portable electronic device of the user. The user would then input their desired destination using voice commands. The device then finds the best route to the destination and guides the user there using audio feedback. Transmitters placed throughout a building and a receiver integrated into a cell phone or PDA will allow the device to know its current location. The software used in the design consists of signal reception, voice recognition, path planning, and audio feedback.
