When he was 13 months old, Daniel Kish lost both eyes to retinal cancer. Driven by fearless curiosity, he taught himself to navigate by clicking his tongue and listening for echoes -- a method science calls echolocation, and that Kish calls FlashSonar.
In 2000, Kish founded World Access for the Blind as a platform to teach FlashSonar, along with other methods that the blind can use to “see” and that the sighted can use to expand their awareness. Kish and many researchers believe that echolocation produces images similar to sight, and allows the visually impaired to transcend the limited expectations of society.
“Daniel Kish has been sightless since he was a year old. Yet he can mountain bike. And navigate the wilderness alone. And recognize a building as far away as 1,000 feet. How? The same way bats can see in the dark.” — Men’s Journal, March 2011

Short recaps of these bold talks … The logic of the young mind. Scientists have to make generalizations on tiny amounts of data – and so do babies. Laura Schulz investigates […]

He let Kate Torgovnick May tag along as he got ready for TED.
