Daniel Kish Uses Echolocation To Navigate

Description:  Daniel Kish lost his eyes to cancer before he was 13 months old. He uses echolocation by listening to the reflection of sound waves to navigate in 3D space. He can even ride a bicycle. In addition to being an incredible story of perseverance this is a perfect phenomenon for a unit on waves. Sound waves are reflected, absorbed, and transmitted through objects in the environment and Daniel can sense the changes in energy of the returning waves.

"They call me the real life batman. My claim to fame is that I click," explains Daniel Kish. His organization, World Access for the Blind, trains the visually impaired to achieve greater freedom through echolocation, a technique that simulates a bat's night vision of perceiving the environment through sound.
