Sure, we've seen brain power used to give mobility back to the immobile, but a new development in Europe is one-upping current efforts by adding in a hint of artificial intelligence to the tried and true brain-computer interface. The MAIA BCI not only converts signals emitted by the brain into actions -- such moving a wheelchair forward -- it also thinks for itself when needed in order to assist the user in getting where he / she wants to go. Essentially, the individual need only think about going left or forward (for example), and the machine itself will automatically detect obstacles and potential barriers in order to move more efficiently. As it stands, there's still quite a bit of testing to be done before MAIA-based wheelchairs would be available to the public, but researchers are already hoping to integrate said technology into artificial limbs and the like.

It's certainly not the first to toy around with mind control as a means of fun and games, but OCZ looks like it may be among the first to actually get a product out the door, with it now set to launch its Neural Impulse Actuator "brain mouse," or NIA for short. According to Daily Tech, the device makes use of a combination of EEG readings, muscle movement, and eye movement to control a given application which, in this case, is mainly intended to be games. Needless to say, the contraption will take a little getting used to, but OCZ says that most users will get the hang of it "within hours" after a little practice, and that they'll eventually even be able to increase their reaction time compared to a standard mouse. You'll also not surprisingly need a fairly decent PC, as the NIA has been designed specifically for multi-core systems, and a good bit cash to spare, with it set to run $300 when it launches sometime in the not too distant future (it's going into production next week).

The idea of wearing a funny hat to mind control software is certainly nothing new 'round these parts. Now Emotiv Systems returns with an update to their Project Epoch USB headset. Crave went hands-on with the system which required a short, six-second calibration before entering the first "game." At that point, Crave was able manipulate a simple cube on the screen with varied success at making it disappear or pull forward. Oooh, what fun! Mind you, it's just a prototype and we've seen this tech applied to old-school arcade games like Pong and Space Invaders to great effect. You'll get your chance soon enough as Emotiv plans to launch the first thought-controlled, consumer gaming device this Christmas for $299 with at least one bundled PC game. One more picture of that Alien face-hugger of a headset after the break.

We were fairly certain we'd reached the apex of human-computer interfacing when that 14-year old kid started blasting Space Invader baddies using only his mind, but we were oh so very wrong. Some University of Washington researchers have managed to jack a grad student into their humanoid robot and perform minor tasks. The big news is that this time, unlike that MRI-based Asimo control we saw earlier this year, the brain waves are being read by a mere cap with 32 electrodes on it, meaning the project uses much messier brain data to control the bot. Because of the type of brain readings they're getting, the bot is semi-autonomous, using human control for making the decisions based on video cameras, but managing the actual mechanics of the motions on its own. Right now the bot can only manage to pick up simple shapes and move them to another location, but the eventual goal is a human-controlled robot that can function in human environments, learn from its surroundings and perform meaningful tasks for its human masters.

Compared to other advances in the world brain-controlled interfaces, Hitachi's latest development may seem a tad unimpressive, basically amounting to a thought-controlled switch. But, connect that switch to a model train set and you've suddenly got something that's a heckuva lot more impressive -- at least on first glance. To get that train rolling, Hitachi uses optical topography to map changes in blood flow in areas of the brain associated with mental activity, translating those changes into voltage signals to flip the switch on and off. Of course, Hitachi eventually sees the tech allowing for a much greater degree of control, with one of the goals being to help paralyzed patients become more independent. They also seem to think they're on the fast track towards commercializing the technology, saying it could be available as soon as five years from now.
