As a current PhD student working in this area, I caution you about getting too excited about the Emotiv EPOC. We've got one in the lab we've started to work with as a potential low-cost EEG system. The out-of-the-box software is kinda hokey, so you may end up with an expensive novelty you use once or twice. On the technical side, it does seem to be the best current option for consumer EEG, though most of these device…

Have you worked with the open source python library for it?

No, I haven't, though I'm interested in which library are you referring to. We've been developing our own Python wrapper interface to their API, though this is to share a common interface with the other EEG DAQ (e.g. g.tec) Python wrappers we've been developing.

(I've heard a few people make similar complaints to yours, which is really really saddening to me. Regardless I'm still going to buy one and see what I can do with it :))

I'm not being clear, I don't think that thinking the words "left left up up" would be detectable through EEG. When I say detecting movement, I mean things like imagining moving a hand, a foot or a tongue. These movements use distinct areas of the brain so you can distinguish between them by looking at where on the scalp the change occurred. This is done in ways that are known to be close to perfect. However, you prob…

Well all you would really need are some easily detectable signals. So if move hand, move foot, move eyes, etc are all easily detectable then you have the basis for an interface. After that it's just a matter of building the interface around those limitations. It wouldn't be mind reading (not even close), but it seems like you should be able to get a reasonably good UI going.

I doubt it. Firstly, you will have to provide a method to filter out real movements from intended ones. A sensor on a few muscles may help, but sticking them on your skin every morning would not help towards the goal of "Reasonably good UI".

Secondly, I am not sure one can learn to almost unconsciously think about certain movements of bodily parts. Chances are this will keep requiring too much apof one's attention.

Thirdly, I think temporal resolution will be awful. Even if you can learn to think about say 3 movements simultaneously, I doubt you will get this above a byte per second of bandwidth. Written text is around a bit/character, so that would likely be way below slow speech.

Most of this is opinion/guessing, so feel free to correct things.
