Play Video Games... With Your Mind! Mwahaha!

This seems like something that would be invented decades from now, when I'm a wrinkly old lady grumbling about the good ol' controller-based console days ("What's a Wii, Great-Great Grandma?" the younglings will ask). But at CeBit, the "world's largest trade fair showcasing digital IT and telecommunications solutions for home and work environments" held annually in Hannover, Germany, the folks at Engadget got a chance to witness firsthand G-tec's EEG Electrode Cap at work:
The system works by cleverly measuring fluctuations in electrical voltage in the brain and then translating them into computer commands. The technology has already been commercialized into the size of an iPAQ Pocket PC for hospitals and research institutes. It costs about $5,000 with a 99 - 100% level of accuracy for "trained subjects."
Without the device, the Engadget editor played a game of Pong and got pwned (10-4 was the score) by a person wearing the cap who only began learning how to use it the the day before: "Our competition sat smug in his stool thinking about where he wanted his paddle to go, as we flailed about helpless with mouse and keyboard in a wake of alpha waves." That's pretty crazy stuff, and certainly more useful than this hands-free headgear.

It'll go into the same closet they stuffed VR technology and all the rest of that stuff that sound all futuristic and fun, but ends up to dificult or expensive or whatever to utilise in everyday gaming.
If I read it correctly, this stuff has to be in contact with your skin.
So, if I want to play, I'll have to shave my head?
Oookay. How fun :D
Maybe it's like an EEG, and you just smear K-Y Jelly into your hair... :)
