The Smart Cane contains an ultrasonic sensor that is paired with aminiaturenavigational system inside a messenger style bag worn across the shoulder. For the test, the students installed identification tags between twobuildings on the campus in Mount Pleasant, Mich. A speaker located on thebag strap gave audio alerts when the system detected an obstacle and
toldthe user which direction to move. Students wearing glasses that simulate visual impairment tested the cane. The students also created a vibrating glove to assist those who are
bothvisually and hearing impaired. Yelamarthi said it's one of the first outdoor applications of RFID and saidhe plans for students in upcoming classes to further refine the systemwhilehe seeks grants to speed the research.
