NSF Highlights Tongue Drive System Technology

August 4, 2011 -

The National Science Foundation has awarded a grant to GA Tech Research Corporation at the GA Institute of Technology for an innovative technology that lets the user move wheelchairs and mouse cursors with their tongue. A team of engineers at the GA Tech Research Corporation has developed a wireless and wearable assistive technology that can convert the user's tongue motions to specific commands such as moving a mouse cursor or a powered wheelchair.

In testing the advanced prototypes, individuals with high-level spinal cord injuries and other severe disabilities were able to move objects with ease. In one trial individuals with spinal cord injuries showed that the average speed of information transfer between participants and the computer was 95 bits/min--more than twice the bandwidth of the fastest brain-computer interfaces that have been tested on human subjects.

More from the NSF site:

"A team at the Georgia Institute of Technology, led by Maysam Ghovanloo, developed the system, which uses magnetic-field sensors mounted on a headset to detect a small magnetic tracer the size of a grain of rice on an individual's tongue. A novel signal-processing algorithm running on a laptop that wirelessly receives the measured magnetic fields associates the subject's tongue position to a set of six user-defined command positions within their mouth in real time. For example, subjects can touch one of their incisors with the tip of the tongue to move the wheelchair forward or one of their left molars to move a mouse cursor to the left."

The subjects also had immediate and full control over a powered wheelchair and were able to perform complex wheelchair navigation, such as driving through an obstacle course. Future development of the Tongue Drive System will include increasing the number of commands, and turning the tongue "into a joystick" by adding proportional control capabilities, and incorporating all the electronics in a dental retainer that can be hidden from sight.

Andrew EisenAnd, predictably, it encouraged more parody accounts, having the exact opposite effect than what was intended.09/21/2014 - 7:07pm
E. Zachary KnightThis is called a police state people. When public officials can send SWAT raids after anyone for any offense, we are no longer free.09/21/2014 - 6:41pm
E. Zachary KnightJudge rules SWAT raid tageting parody Twitter account was justified. http://www.theguardian.com/world/2014/sep/19/illinois-judge-swat-raid-parody-twitter-peoria-mayor09/21/2014 - 6:41pm
MechaTama31quik: But even if it did break, at worst it is only as bad as the powder. Even that is assuming that it is dangerous through skin contact, which is not a given if its delivery vehicle is a syringe.09/21/2014 - 4:30pm

quiknkoldSyringes can break. And in a transcontinental delivery, the glass could've broken when crushed. I work in a mail center. Shit like this is super serious09/21/2014 - 3:25pm
E. Zachary KnightIt doesn't matter what is inside the needle. As long as it requires him to take the step of purposefully injecting himself, the threat of the substance is as close to zero as you can get.09/21/2014 - 1:27pm
quiknkoldEzach: I'm not talking about the needle. I'm talking about what's inside. Geeze. Depending on what it is, the sender could be guilty of bioterrorism.09/21/2014 - 12:51pm
E. Zachary Knightquiknkold, No. That syringe is not worse than white powder or a bomb. The syringe requires the recipient to actually inject themselves. Not true for other mail threats.09/21/2014 - 12:49pm
Andrew EisenThe closest to a threat I ever received was a handwritten note slipped under my door that read "I KNOW it was you." Still no idea what that was about. I think the author must have got the wrong apartment.09/21/2014 - 12:28pm
InfophileThat's what they call it? I always called it hydroxic acid...09/21/2014 - 11:57am
MaskedPixelanteProbably dihydrogen monoxide, the most dangerous substance in the universe.09/21/2014 - 10:14am
james_fudgewell I hope he called the police so they can let us all know.09/21/2014 - 9:07am
quiknkoldIt's pretty gnarly. Depending on what it is, it could be worse than white powder or a fake bomb.09/21/2014 - 9:06am
james_fudgeI just looked it up on UPS.com09/21/2014 - 8:56am
james_fudgeand expensive for an American to ship to London.09/21/2014 - 8:55am
E. Zachary KnightThat is pretty scary. Would have been worse if it were a fake bomb or white powder.09/21/2014 - 8:49am
quiknkoldThere's some more tweets regarding it with more pictures09/21/2014 - 8:09am
quiknkoldMilo Yiannopoulos was mailed a syringe filled with clear liquid. He claims it's anti gamergate harassment. Mentioned on his twitter twitter.com/Nero/status/51366668391625523209/21/2014 - 8:07am
Andrew EisenNow, having said that, what sites are you reading that are claiming that if "you self-identify as a Gamer, you're immediately the problem" or that gamers are "obligated to stop harassment"? Or was that hyperbole too?09/21/2014 - 1:03am
