Direct Brain-to-Game Interface Worries Scientists

This part is pretty ludacris though:
"Emotiv CEO Nam Do declined to explain how his company's technology works, but denies it's a form of neurofeedback... 'There is no two-way interaction, and the technology does not require the user to train their brain to get into a predetermined state in any way.'"
If you use your EEG signals alone to change things on a computer screen, then it's neurofeedback. This guy is claiming that if it's not done in a clinical setting, then it's not neurofeedback; he's wrong. You're still using your brainwaves to go in a certain direction (which actually IS a two-way interaction). That's all neurofeedback is. I trust that Emotiv and NeuroSky will do whatever controlled clinical studies the FDA makes them do, but the fact that they don't consider EEG-based video games to be neurofeedback is a little worrisome. Then again, no one ever did any clinical studies on the neurological effects of TV watching.
This is like a commercialized version of the neurofeedback games that were at the NASA party back in April, which were basically just move forward & move backward by collecting blood in the front of your brain and then calling it quits when you started to get a headache. Since it's nearly impossible to deliberately do anything complicated with EEG signals, I'm not sure EEG-based gaming is ever really going to take off. I'm interested to see where this goes though.
