Brain-Computer Interface Works With Speech Centers

Posted by Unknown on from the dragon-naturally-thinking dept.

Scottingham writes "Science Daily reports on new research that uses electrodes placed in the speech centers of the brain to move a cursor around the screen. Participants were instructed to utter different vowel sounds while their neural activity was parsed and analyzed. Once analyzed and connected to a cursor-control program, participants quickly learned to use the different vowel sounds to move a cursor around a screen. The system can distinguish between actual speech and the cursor controlling thought sounds."

    You know what? This is awesome. The other day I was a little down and pessimistic that the aught years didn't really seem to have the leaps and bound of progress that decades in the previous century did. I mean, jets, radar, space travel, computers, the Internet, medicine, manufacturing, plastics and other materials. I dunno, maybe I wasn't paying attention or something. But it seems like between 2001 and 2010, the biggest move forward was lolcats and smartphones. And for as awesome as smartphones could be, mostly they're just expensive toys.

    But with this and other such recent news of progress I feel like this is actually going somewhere. We'll have direct neural interfaces of one shape or another within my lifetime.

    It's just kind of exciting to look forward to.

      If anything, it's more fitting to be depressed because space travel has advanced far, far less over the last 50 years than just about anything.

      But no, the last decade did bring a fair bit of innovation, I think. Just a few things...

      On the Internet front, not much technically new, but last decade is when it truly became widespread globally, instead of being largely limited to a few rich Western countries. From 2000 to 2010, Europe went from 105 million to 475 million Net users. Mideast went from 114M to 825M. Africa, where overall use remains very low, still went from 4M to 110M.

      A lot of interesting stuff happened with cybernetic implants / mind controlled tech. The BrainGate allowed paraplegics to mentally control a robotic arm (see Matt Nagle).

      Stem cell research has shown some very promising things. Shinya Yamanaka came up with some method to use non-embryonic stem cells by some reprogramming process I won't claim to understand.

      Spirit & Opportunity discovered proof of liquid water once on Mars, while frozen water got discovered on the Moon. And the first private spaceflights took place in this decade.

      As far as gadgets and such go, some are also rather important. Digital cameras became commonplace, which I'd say is a more important innovation than smartphones, for now at least. In terms of ease and convenience, Wi-Fi and flat LCD screens became popular - with Wi-Fi being widely used and LCDs essentially pushing CRTs off the market, personal computing became easier.

      Come to think of it, mobile phones! Last decade is when they went from expensive to common. In 2000, in my area at least, they'd be mostly used by businessmen and those who really had a need, but over a few years mobile phones became so widespread that grannies and schoolchildren have them now, in the last few years they've also caused landline use at home to become less prevalent.

      Perelman's proof of the Poincare conjecture gave a solution to one of the most important outstanding problems in mathematics.

      A functional memristor was built at HP. This can be a very important technology.

      3D printing has become feasible for use.

      And to finish this post, Mycoplasma laboratorium. One of the most potentially interesting developments in recent times, while it could also pose major ethical issues and possible misuse.

      That is, indeed, kind of a neat scientific advancement.

There have been work around systems proposed in the past where you connect the neural sensor to movement centers, then retrain the brain so that certain movements can be interrupted as speech; but this is far more direct and requires far less retraining. The cursor moving thing is really more proof of concept. The idea is to give voices to mutes.
