Thanks Itaxpica. I come from an academic cognitive neuro background too and shared a lot of your concerns. We've shown empirically that you can use an active (non-gel) EEG system to do limited things. We are interested in mindfulness and meditation, which often involves sitting still and closing your eyes. These facts make it easier to use our detection algorithms successfully than it might in other realms. Check out neurosky, emotiv, interaxon and other folks to see products in the space--> still in its infancy, but we're practically seeing results for our narrow focus, which is meditation.
