Like Emotiv's Project Epoc, OCZ's Neural Impulse Actuator turns your brain into a video game controller. The headband's neural sensors are located up front, reading your neural activity the same way that an electrocardiograph reads your heart (though fortunately the NIA doesn't require you to lube up before putting the headband on). OCZ claims the device has a 2-minute learning curve. The NIA is set to come out at the end of the year for $300. It looks less intrusive than the Epoc, but unfortunately it's wired.
Check out the post-jump video to see the device in action.
