Watch as Erik Weihenmayer experiments with the Brainport Vision Device, a revolutionary new technology enabling a blind person to see with his tongue. Mounted on Weihenmayers head is a small video camera which translates visual information to a credit card-size tongue display. Four-hundred tiny pixels present electrical patterns on his tongue, which Weihenmayers brain then interprets as a visual picture in three-dimensional space. Watch as he uses the device to read words and numbers on note cards, to play tic-tac-toe and stone-paper-scissors with his daughter, and to rock climb.
