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.

EA has shuttered Maxis (The Sims, SimCity). Should it keep the Maxis name alive?:

Andrew EisenDoesn't matter if you play more games where the cast is the same basic character model. In this type of game, being able to easily tell which character you're looking at serves an important purpose.03/06/2015 - 7:29pm
ZippyDSMleeMechaCrash:Meh I've played more stuff that had pickups rather than set class's.03/06/2015 - 7:22pm
MechaCrashZarya's body type also has a pragmatic reason. Ever notice how in TF2, you can immediately tell who's who because they all have very different profiles? Same deal with Overwatch. If you see Zarya, you KNOW it's Zarya.03/06/2015 - 6:32pm

ZippyDSMleeNearly anyway the new UT game has color at least. And wow they changed to C++ 0-o03/06/2015 - 5:43pm
ZippyDSMleeCraig R.: Same reason why UT99/04 and UT3 are diffrent, gritty is the thing to do...at least it was... nearly everyone else grew out of dark and gritty….03/06/2015 - 5:40pm
ZippyDSMleeI doubt each model of characters in COH/COV/CO,ect are kept as unique model data.03/06/2015 - 5:39pm
ZippyDSMleemodel shape.03/06/2015 - 5:38pm
ZippyDSMleeMonte:I think it’s more a part of the engine, yes its more work but you should be able to have some sort of physical collision system in place to keep arms and stuff from clipping. Outside of that the data stored is just number variables to change the m03/06/2015 - 5:38pm
Andrew EisenAt least she's smiling in one of the pics.03/06/2015 - 5:31pm
Craig R.It's like somebody took the color palette and decided that anything approaching 'bright' is unacceptable03/06/2015 - 5:30pm
Craig R.Scratching my head as to why DC shows are as dark and drab, color-wise, as the movies look to be03/06/2015 - 5:30pm
MonteIf for instance you make the character fat, you need to make sure the animation of the character moving his arms and gun around, won't result in them clipping into the character's larger stomach03/06/2015 - 5:22pm
Monte@zippy, I imagine creating customizabel, vastly different body types would add a lot more complexity. Like making sure the character's animation still looks right. It can be done, but it can get complicated03/06/2015 - 5:19pm

prh99I think it probably far easier to add a character than strip a feature from game engine that was baked in from the start.03/06/2015 - 4:45pm
Andrew EisenAs I've said twice already, yes, strides in one area do not absolve anyone from criticism over where else they're falling short.03/06/2015 - 3:04pm
ZippyDSMleeI know I know one thing is not the other. Still worth nagging about.I still do not see why they do not put in body sliders and elt people make thier own body types....I'd do fat/pudgy or chibi befor I do ultra generic prefect body......03/06/2015 - 2:59pm
Andrew EisenAgain, yes, it's dumb that there's no offline mode and that's certainly something worthy of criticism but that does not make any positive moves Blizzard makes any less positive. A bummer that the issue that's more important to you wasn't addressed? Sure.03/06/2015 - 2:46pm
ZippyDSMleeBut...but... but my butthurt!!111 LOL :P03/06/2015 - 2:45pm
