'Smart cane' reads e-tags to help blind AP 5 August 2009, 12:28am IST DETROIT: A cane equipped with the technology that retailers use to tag merchandise could help blind people avoid obstacles. An engineering professor at Central Michigan University has created a 'Smart Cane' to read electronic navigational tags installed between buildings to aid the blind in reaching their destinations more easily. During the spring term, Kumar Yelamarthi, the project leader, and five engineering students tested the cane, which is equipped with Radio Frequency Identification technology, similar to what retailers put on products to keep them from being stolen. The students also created a vibrating glove to assist those who are both visually and hearing-impaired.
