Extraordinary Blind People - Seeing with Sound
Daniel Kish is the Co-founder and Director of World Access for the Blind (www.worldaccessfortheblind.org). He lost his sight as an infant. He discovered that by clicking his tongue on the roof of his mouth, he can identify the surrounding objects close to him. The technique is similar to bats and dolphins, called echolocation. Now he is teaching blind people how to navigate new locations safely. So the blind people can running, biking and hiking alone.
The following videos show the extraordinary people - Daniel Kish, Ben Underwood and 7-year old Lucas Murray using echolocation to visualize the outside world.
