I don't know much about this offering, and I am not a neuroscientist/md, but I do know many well known and respected neurologists/epeleptologists and have worked with them for quite a while (I currently work in the Dept. of Neurology at a very well known institution). Nevertheless, even I know that signals acquired from surface electrodes are very difficult to "read" let alone useful to manipulate anything. For one, a patient who is awake and moving will generate a very difficult to ascertain signal to noise ratio due to too much muscle artifact. The best/most reliable I have seen via surface electrodes are simple binary commands along the lines of "move the dot on the screen up or down" (my brother did that as his senior thesis for his undergrad bio-engineering major). Now, the guys at emotiv may have devised a way to enhance the electrodes and/or filter out artifact but I would really have to put this to some of my scientist buddies who would actually know what is going on under the hood here. I am inclined to think they have not because I haven't heard any excitement from any of the neurologists in the epilepsy division. I've seen expert technicians actually apply electrodes both surface and implanted (aka. in the operating room with ones brain exposed). Let's talk surface. There is a lot of expert care and skill that goes into setting up electrodes (and in specific places). On top of that, the electrodes are generally coated with a gel. All of this to enhance the electrical signal. The headset from emotiv looks like it is dry and how do you know if it is positioned properly? tl;dr, I would love to think this has real value but I just don't think so.
