An engineering professor and five students at Central Michigan Universityhave created a ''Smart Cane'' to read electronic navigational tagsinstalledbetween buildings to aid the blind in reaching their destinations moreeasily. ''This project started as a way for me to teach students to see andunderstand the ways that engineering can be used for the greater good,''said Kumar Yelamarthi, the professor and project leader. ''We wanted to dosomething that would help people and make our campus
more accessible. '' During the spring term, Yelamarthi and five senior engineering studentstested the cane, which is equipped
with Radio Frequency Identificationtechnology, similar to what retailers put on products to keep them frombeing stolen. The Smart Cane contains an ultrasonic sensor that is paired with aminiaturenavigational system inside a messenger style bag worn across the shoulder.
