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.

james_fudgeQuiknkold: Let me ask you- how many of those 'gamers are dead' articles did you see here? Because apparently i'm part of some vast conspiracy.09/18/2014 - 5:18am
NeenekoAh, that old straw man. That is one of the ironies about the discussion, the whole point is showing how good people can still have problems with sexism and not realize it.09/17/2014 - 9:11pm
Andrew EisenYes, there have been a handful of op-eds suggesting that the term “gamer” has become tainted (two that I know of) but that’s the opinion of only a few. I've seen an equal number from those who disagree.09/17/2014 - 8:55pm
Andrew EisenExcept, you haven't provided a single example of a site that’s actually calling gamers a "collective of Sexist White Bigoted Basement Dwelling Manchildren."09/17/2014 - 8:55pm
TechnogeekIf you want to make the stereotype of gamers less painful, try calling people out when they do bad shit rather than handwave it away as "not all gamers". Even if it is a few bad apples, that'll still more than enough to spoil the barrel.09/17/2014 - 8:53pm
quiknkoldI'm not going to Sell Gamergate anymore. It can sell itself. But I will sell the integrity of the Gamer. That we are still good people, who create and donate to charitys, Who engage with those around us and just want to have a good time.09/17/2014 - 7:35pm
quiknkoldpeople should not be harrassed and punished for the actions of a few. I've always welcomed and accepted everybody who wanted to join in. Who wanted to make them, or play them. I love good strong female protagonists, and want more.09/17/2014 - 7:35pm
quiknkoldOne of the tennants of Gamergate is to stand up against Harrassment. That Gamers arent like those assholes. We can argue for days if the Sexism or Antifeminism or corruption is there or not, But the one thing I believe in and wear on my sleave is that09/17/2014 - 7:35pm
quiknkoldBut there were these websites, attacking me and people like me, for the actions of a few. and then others joined in on Twitter and other places. there was a hashtag that said "explain in 4 words a gamer" and it made me sick.09/17/2014 - 7:35pm
quiknkoldManchildren who are awful people and that the Identity of the Gamer should die. This hurt me personally. I've always identified as a Gamer. Even in my childhood years, I was a Gamer. All my friends are Gamers. Its one of the core parts of my identity.09/17/2014 - 7:34pm
quiknkoldUltimately, With the whole Gamergate thing, I jumped on it due to the harassment. A small number of assholes harrass Anita and Zoe, and then all the publications lumped together Gamers as this collective of Sexist White Bigoted Basement Dwelling09/17/2014 - 7:34pm
quiknkoldEZacharyKnight : Lemme ask you a question. We have people who cling to walls, people who fire lasers from their eyes, people who can shapeshift....and yet fabric needs to be upheld to RL physics?09/17/2014 - 6:54pm
james_fudgebody paint?09/17/2014 - 5:33pm
E. Zachary Knightquiknkold, I stand corrected on the buttcrack thing. Still, I know of no fabric that actually does that.09/17/2014 - 5:05pm
Andrew EisenSo... it's unethical to discuss the ethics surrounding public interest vs. personal privacy?09/17/2014 - 4:45pm
prh99The source for the game was just released not long ago, it's at https://github.com/keendreams/keen09/17/2014 - 4:43pm
prh99An Indiegogo champagin bought the rights to the early 90's game Keen Dreams to make it open source and release it on GOG etc. https://www.indiegogo.com/projects/let-s-get-keen-dreams-re-released-legally09/17/2014 - 4:42pm

Andrew EisenI read the Kotaku story. Nowhere does it say anything close to "Gamers are white bigoted sexist losers." It's commenting specifically on the crap being slung at people discussing gender issues in games. So, what's the problem?09/17/2014 - 4:06pm
Andrew EisenYeah, I can imagine Spiderwoman posed like in your second link.09/17/2014 - 4:00pm
