Daniel Kish was featured in Derren Brown's 'Misdirection' series. The clip here shows him using echolocation to describe the shape of a car and ride a bike: http://www.youtube.com/watch?v=MjFcvixIRxs

'You might think of it like being in a choir or an orchestra... The world is like a living symphony... This car is kind of like an instrument, except that, instead of making its own sound, it's reflecting sounds I'm making.'

Extraordinary.

How do you "explain" to someone who was born blind that he is "blind"?

Beautiful question. You could also ask if blind people are able to perceive vision in dreams. To which the answer, I believe, is that they simply cannot, due to the fact that their brains have no notion of a visual image.

I'm not sure about that. Sight happens in the brain. When the eyes don't work this doesn't have to mean the visual part of the brain doesn't work.

No more print articles, please. I'm tired of print dialogs popping up, un-asked-for. Use Readability if you don't like the layout. http://www.mensjournal.com/the-blind-man-who-taught-himself-...

It was probably done to get the article onto one page, not the five that the normal article is.

'...dreaming is a gradual cognitive achievement that requires the development of visual and spatial skills and other forms of imagistic skills as well.'[1]

Those who've never seen, or who were blinded very early, have auditory dreams. (They dream in sounds.) Those who were blinded after the age of around seven -- when the ability to form mental images necessary for dreaming develops -- are able to dream in pictures.

I wonder how a brain that has never "seen" an image would percieve technology to allow the blind to see using this:

Not sure why he wouldn't use this, this seems vastly superior to the system he uses: http://www.youtube.com/watch?v=8xRgfaUJkdM&feature=playe...

I don't know about that. While that system is clearly easier to use, from what I've heard about echolocation it provides much more detail than that system.

If you look at my other post, I linked to a video of a kid who used echolocation. He could distinguish objects - he walked past two garbage cans in the street, and said "Is that a car? clicks his tongue several times No, it's a garbage can."

Kish figures it would require $15 million to prove whether or not his idea is feasible. He fears he’ll never get the opportunity.

Sounds like he needs some real angels, those who measure the success of their investment in something bigger than dollars. How does one go about finding and pitching to them?
