Other editions of book Imitating Nature - From Bat Sonar to Canes for the Blind

Inspired by bats' ability to "see with sound," three scientists from the University of Leeds in England used their knowledge of echolocation to invent an ultrasonic cane for the visually impaired. Echolocation by bats is explained, as well as the electronic mimicking of ultrasonic mapping, how it works, and how the UltraCane is used by blind individuals.
