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.


Created in fulfillment of the course requirements for ENGG*3100 Engineering and Design III. This course combines the knowledge gained in the advanced engineering and basic science courses with the design skills taught in ENGG*1100 and ENGG*2100 in solving open-ended problems. These problems are related to the student's major. Additional design tools are presented, including model simulation, sensitivity analysis, linear programming, knowledge-based systems and computer programming. Complementing these tools are discussions on writing and public speaking techniques, codes, safety issues, environmental assessment and professional management. These topics are taught with the consideration of available resources and cost.
