We already know that NeuroSky is bringing us the mind-reading mindset for your gaming pleasures, but we got a first-hand look at the device here at TGS. At first glance, the headset may appear to be just another white set of over-the-ear headphones, but a little boom that gets all cuddly with your forehead measures how well you are concentrating on in-game objects.
While this may sound like a bunch of hoopla, keep in mind that mega-developer Square Enix is already on board with "Judecca," a zombie thriller that forces you to concentrate your way into seeing your enemies. After holding up your hand, you then concentrate on a glyph that glows in direct relation to your ability to concentrate, opening up what's called your Devil's Eye. Once you're in a zen-like state, you can see Judecca's zombies and unleash some kill. You can also show your concentration skills enough to walk through walls, naturally.
In our limited time trying the tech with Judecca, we were indeed able to induce some sort of concentrative state, even with the distractions of a giant Japanese gaming convention. As for how long we'd want to play something like this before switching to something involving, say, just pushing buttons and killing enemies, we're not so sure.
