In this paper we present a new systems for the navigation of visually impaired persons around campus. The main idea is a range finding device that allow the user to sense what is around them. The design consists of 3 ultrasonic sensors on a pair of glasses connected to a micro-controller which in turn moves 3 linear actuators on the skin giving the user a sense of what is around them.

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.
