Wheelchair Controlled by Thought 84

Posted by samzenpus from the just-like-xavier dept.
macduffman writes "New Scientist reports on another development in interfacing with the central nervous system. The system 'eavesdrops' on signals sent from the brain to the larynx, so even people who lack the muscular control to vocalize a command can operate it. The potential applications of this technology are as varied as human imagination, among them: allowing a person who has lost speech capability to vocalize again." From the article:"The wheelchair could help people with spinal injuries, or neurological problems like cerebral palsy or motor neurone disease, operate computers and other equipment despite serious problems with muscle control. The system will work providing a person can still control their larynx, or 'voice box,' which may be the case even if the lack the muscle coordination necessary to produce coherent speech."

    If it's eavesdropping on the signals sent to your larynx, does that mean that you can't talk and drive at the same time?

      Not to be rude, but how is this insightful? The throat and mouth follow the commands of the brain, therefore unless they have independent intelligence they would not add any additional information.

      Well, how much information do you really need to drive a wheelchair?

      Rotate left
      Rotate right
      forward
      stop current action

      Not much. I'm sure there are four discernible signals to the larynx, probably more. Just a quick guess, but you could probably detect the following sequences of long/short "uh" sounds:

      short short (uh uh)
      short long (uh uuuuh)
      long short (uuuuh uh)
      long long (uuuuh uuuuh)

      There's four signals.

      • Man, if I end up on such a wheelchair, I sure hope my larynx is fucked up too. Because otherwise it sounds like an orangutan on a wheelchair. "Uh uh uuuuh uh uh uuuuh uuuuh uuuuh!" Throw in some chest thumping and people might try to appease me with bananas.

        I think you meant the other order there. Not "uuuuh uuuuh" for stopping! I think short short is for stopping. Much more important than rotating. I mean it's gonna be "uuuuh... oops, didn't stop, I feel off a cliff."
      • even if there are only 4 commands, the percent error this machine should have in discerning between the commands should be less than 0.1% (1/1000). Think about it, how often do you tell yourself to stop walking? Now what if one of those is to tell yourself to stop walking across the street. while this technology seems useful, they'll sure have to test the hell out of it before it gets anywhere near production.

      How long until the NSA makes us all wear one?

      For a short time in college I was on a research team looking into this kind of stuff. (Way back in '93, this was) The electrical impulses that are meant for your vocal chords, but are suppressed because you don't want to (or can't) speak are called "covert oral behavior." Anyway, even back then, we were working on training up neural networks to translate the signals into words/phonemes. I'm sure the technology has come a long way since then.

      Right around 9/11 and the whole Gitmo thing I started thinking, "I'll bet covert oral behavior detection is being used to interrogate prisoners." The thing is, the signals "leak" down your nerves when you only think words, but don't say them. The trick is being able to interpret them and translate them to words. Not easy by any stretch, but once successful it would be the closest thing to ESP around.
