Blind Soldier Uses Tongue To "See" 107

Posted by CmdrTaco from the in-the-future-we'll-all-be-robots dept.
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."

      Yet another example of the adaptability of the human brain.

      More than some might realize.

      Some decades ago (when a camera was not practically portable) a similar device was built with an array of vibrators on the back for the interface. This worked as well (though the resolution was necessarily low both because of the size of the vibrators and because the back has a low density of touch sensors).

      But one event was telling:

      At one point the camera tipped over into the scene it was viewing. The subject reflexively threw his hands up to "protect his eyes". (Later the blind-from-birth subject said he now had a referent for the word "looming".)

      This event implies that the subject's brain had routed the input from the touch sensors on his back into his visual processing at a stage before the "dangerously close incoming object" detection. So he was "really seeing" without eyes.

      • This device probably derives from an ongoing study at the University of Wisconsin. In this study the researchers discovered that after several weeks of using the device, the information it was providing would begin to be processed by the visual cortex, confirmed by actual measurement of brain activity. So as ircmaxell and Ungrounded Lightning noted, there is solid evidence that somehow the human brain is able to reroute connections to ensure that sensory input is processed properly. I wish I could cite a sc

        • The choclea evolved from the lateral line of the fishes, coiling up to fit inside the head and modifying the wave path so what used to map into direction now maps into pitch.

          Perhaps that might be reverse engineered so we can generate a sound that produces the original "fish acoustic vision" sensation of directionality and intensity for impulse noise ("something is twitching THERE").

          (And perhaps that's what the "sounds like modem tones, maps into vision" thing mentioned earlier is up to?)

  • Wouldn't this affect his taste buds greatly having a feeling of a 9 volt battery constantly?

    • Well it is definitely rewiring tongue sensations for visual images. If he is blind, his sense of taste is already greatly enhanced, since all of his senses should have started using the visual cortex. They are just using some of the visual cortex for visual processing again, but this time via the tongue.

The cells reacting to the shocks may be mechanoreceptors, like the cells responsible for the sense of touch in skin. The shocks are inadequate signals for them as well, but still closer. The brain just started to "see" meaningful information in those shocks. It's similar to the guy (link lost, lazy to google) who made himself a kind of belt with vibrating motors around it coupled to
