In this paper we present a new system for indoor blind accessibility. The main idea is an intelligent cane which is capable of navigating a fully blind person through the use of Radio Frequency Identification (RFID) technology. The design consists of a modified white cane, containing RFID transponders which receive information from RFID tags in the hallways. The user wears a headset to give commands and receive information. A rumble feature in the cane is used to give the user directional feedback. The design's directional feedback software was simulated and the results show that the software is successful and will competently keep the user on the path to their specified location.

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.
