I did a final project on the limits of EEG (electroencephalography, or getting-signals-using-electrodes-on-scalp, which is what this is) for a neurotechnology seminar last semester, and compared my findings to the claims made by Emotiv. The result: some of the things they claim this device can do are actually impossible and always will be, and others are extremely unlikely unless they've made some seriously groundbreaking discoveries. (Mediocre two-dimensional movement, for example, has been generated by EEG, but it'd be impossible with their headset unless they have some sick new algorithms.) The professor of the same course actually met with the president of Emotiv, who failed to demonstrate that the device could do anything.
Last I checked, their marketing videos are ridiculously flashy while showing no real control capability. My belief: EEG headsets like these, at best, will be controllable only by facial muscles (which completely overshadow the electrical potential generated by the brain) and by alpha rhythm amplitude, a very slow control signal demonstrated in "BrainBall", which was posted to slashdot some time earlier. At worst these headsets will be near-worthless devices, their sales supported entirely by false promises and media hype.
