Blind Soldier Uses Tongue To "See"

Zen found this story about a blind soldier using a lollypop-sized tongue sensor to 'see.' The system actually enables him to walk and read unaided. The guy says, "It feels like licking a nine-volt battery or like popping candy. The camera sends signals down onto the lollypop and onto your tongue, you can then determine what they mean and transfer it to shapes."

Sweet! Another example of the human mind!

Yet another example of the adaptability of the human brain. I wonder what the resolution of such a system would be? What's the possibility of being able to read with it?

And a minor pedantic point. It's not a sensor on his tongue. A sensor is an input device. This is an output device (relative to the computer "device")...
