Human Echolocation
Ben Underwood had his eyes surgically removed at the age of three due to cancer. He discovered human echolocation at the age of seven and now uses it to accomplish such feats as running, rollerblading, foosball and playing video games. Human echolocation involves creating an environmental image by hearing echoes bouncing from those objects. It is similar in principle to sonar and to the animal echolocation employed by bats and dolphins. Human echolocation has been studied since at least the 1950's but is still not completely understood. Ray Charles was said to use a variation of the technique by wearing hard-bottomed shoes, the change in sound alerted him to when we had passed through a doorway. However, very few people have mastered human echolocation to a superhuman level like Ben Underwood.

This is amazing!!!

It seems too amazing to be true. I'm tempted to believe there's some kind of a hoax going on. I can just barely imagine how human echolocation could reveal a fallen trashcan, but the video game could not possibly provide sound clues to the precise location of someone firing at you. The foosball table also seems like an unlikely spot for sound or smell or touch to provide sufficient information to beat any sighted person.

It may be hard to believe, but it could def. be true. As to the videogame, it all depends on what game you're playing, obviously some games won't work. In college though I watched my roommate beat people left and right in Tekken while sitting BESIDE the TV, facing away from it.

Did I hear correctly that Ben's mother's name was "Aquanetta"?

*holds up paper*

Hey Ben, what colour is this paper?

Yeah, that's what I thought. You're blind to the whole EM spectrum and I'm not. I win =D

that's a little harsh. he may not be able to see the colors, but he can see everything else. you don't win, he wins.

Echolocation is actually pretty easy to do--so long as you're in a quiet environment and get a week of practice--although identifying a 'soft' object might take a while.. I mean lets see this kid walk around in downtown NY and if he can navigate without a stick or a dog then yeah, he's the real deal.

he "sees" better than you do in a pitch black room, or out in the wilderness at midnight with no moon+overcast.

On the other hand, I can tell the difference from a car and a trashcan way better than he can, and given a flashlight, and with even adim light source my vision can match his echolocation.

Bats still do it better

For those of you saying that you are better than him, you're not. And for the person that said bats are better, they are able to do this naturally where as he had to teach himself how to do it.

Sad how many of you are threatened by a blind kid...

I saw the documentary on tv. It was really really cool. I never thought that people could do something like that.
