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.

PHX CorpI'm going to do a test stream later today, if anyone is intrested07/31/2014 - 2:40pm
Andrew EisenYes, I'm such a big Nintendo dork that I read Nintendo's quarterly financial reports.07/31/2014 - 2:09pm
Andrew EisenCool tidbit - Mario Kart 8 sales account for more than half of total Wii U software sales for the last quarter even though it was only available for the last third.07/31/2014 - 2:09pm
Andrew EisenStill a pretty cool promotion. Unfortunately for me, I'm not interested in purchasing Mario Kart 8 and I already owned or didn't want any of the free games on offer.07/31/2014 - 1:43pm
Andrew EisenInteresting that EU had 10 games to choose from while North America only had four.07/31/2014 - 1:41pm
MaskedPixelanteIt certainly worked, I probably would never have bought Mario Kart 8 if it didn't come with a free copy of Wind Waker HD.07/31/2014 - 1:14pm
Andrew EisenI imagine will see similar promotions like "Buy Mario Kart 8 get a download code for one of these specific games" but almost certainly not for all of its (however you would define) biggest releases.07/31/2014 - 11:24am
MaskedPixelanteI wonder if Nintendo is going to be doing "buy one get one free" promos for all their biggest releases going forward.07/31/2014 - 10:48am

ZippyDSMleeWouldn't they be able to afford and get done in a timely manner a general gba emluator for the 3DS? It seems to me if they want to make money off sales they need to do it.07/31/2014 - 7:25am
Sora-ChanAmbassador program, that's what I was looking for. Anyway the other games that have been made no longer exclusive to the early adopters got updates in their software. It'll only be a matter of time more than likely for the GBA to get the same treatment.07/31/2014 - 5:35am
Sora-ChanI might be naming it incorrectly when I say "founder" i mean the program for earlier adopters.07/31/2014 - 5:34am
Sora-Chanthe 3DS's GBA emulator was a rush job due to the founder program. No other GBA titles have been released on the 3DS yet. If/When they do get around to it, they'll more than likely update the emulation software.07/31/2014 - 5:32am
Zenemulator...it's not just a slap job that makes "some" work..they do it for each which is why they work so well. I would rather have the quality over just a slap job.07/30/2014 - 5:48pm
ZenMatthew there is a difference between "worked" and "accurate". You play the Nintendo VC titles they play as damn close to the original as possible. The PSP would just run them as best they could, issues and all. And Masked...EACH VC title has their own07/30/2014 - 5:48pm
MaskedPixelanteOnce again, the 3DS already HAS a GBA emulator, it just can't run at the same time as the 3DS OS.07/30/2014 - 4:54pm
Matthew Wilsonyou cant street pass in ds mode ether, and if moders can make a gba emulator that runs very well on the psp as I understand it. you are telling me that Nintendo devs are not as good as moders?07/30/2014 - 4:49pm
Zenperformance. Halo 1 and 2 worked great because they actually did custom work on each of them...just like Nintendo does now lol07/30/2014 - 4:08pm
Zenexisting hardware while the GBA has to be emulated completely. Same reason the 360 couldn't run most Original Xbox games correctly, or had issues because they just did "blanket approach" for their emulation which led to game killing bugs or horrible07/30/2014 - 4:07pm
ZenSora/Matthew: It's not just Miiverse, but the whole idea of streetpass and things like that would be affected if the OS is not running. And just because a 3DS game can be downloaded and run does not mean that GBA can as easily. Those 3DS games use the07/30/2014 - 4:06pm
