View Full Version : Computer input using only the face, eyes, and mind.

OCZ's Neural Impulse Actuator is a computer input device [marketed as a game controller] that allows the user to perform configurable keyboard commands using only face muscles, eye movement, and thought.

By incorporating an electro-myogram, electro-encephalogram, and electro-oculogram into a small headband and a little black box with a USB connector, the company has developed a control system that can translate eye movements, facial muscle movements, and brain waves into game input.

The NIA software lists eight different inputs in total. The bulk of those inputs are made up by a "muscle" input that tracks facial muscle tension (largely from jaw and eyebrow muscles) and a "glance" control that tracks lateral eye movement. Six brain-wave inputs—three for alpha waves and three for beta waves—fill out the neural control aspect of the NIA. This post by Dr. Schuette suggests alpha waves correspond to aggression and that beta waves can correspond to pain management. For instance, one can trigger the Alpha 2 meter by thinking of an expletive. (emphasis added)
This might cause a problem for some of us... given my propensity to cuss while playing a game, and the constant pain management required to deal with injury, my character would likely spend most of its time running backward and jumping for no reason.

Still, it's encouraging to see a mass-market hand-free computer interface device. I hope this product is successful, and perhaps future versions will expand the capabilities and address some of the issues.

The NIA costs $159.

I keep thinking about this device. Might it be possible to use it to control the pedals in a car? Maybe it could control this contraption (http://sci.rutgers.edu/forum/showthread.php?t=103421). If I had a few extra $$ I'd pick one up just to try it out. My gut tells me that this thing, plus a hobbyist's spirit, might come up with some interesting results.

At one moment the user says he has no idea, about how he control the game(I don't like that). I hope it was just a joke.
The main problem with this approach is because the skull bone is too thick and the brain signal is too weak.

The review I read was generally positive, though it did say the device required a fair amount of practice to master.

My biggest idea for this is that it might be able to replace the accelerator and brake in a car, so that one hand can be free while driving (to eat Egg McMuffins, drink coffee, make phone calls, play with the radio, etc :D) But for that control, obviously eye movement is out. Face tension, maybe, but that would take some careful muscle control. Alpha waves, who knows? The review I read said alpha waves are affected by emotions, like anger. Would a sudden burst of road rage equal full accelerator? That wouldn't work out well!

I have no arm movement, I type with a headswitch and ez keys. I bought a device similar to this one called brainfingers... Needless to say it didn't really work for me and now it just sits in a drawer. I think it's a good idea but just needs to be tweaked a little better

I tried to work with it for months
