When I came home from Switzerland yesterday, The Man was all in a state about NeuroWear, the people behind the technology above.
"Do you think it's real?" he wondered.
Why not. It was only last month that I mentioned mind control tech was the new frontier, and NeuroWear's Nécomimi thing, which is basically a mood ring, doesn't represent the most serious ways in which mind-interfacing technology has advanced (1, 2, 3). But it does represent how cheap the technology has become, how sensitive, and how important it'll be for the future: people are playing with it.
To wit: BCI (brain computer inferface) users can even make beats.
I wouldn't worry about everybody and your mom getting "Nécomimi" bunny ears, though. (I am holding out for a tail.) The money's on the gaming industry, and eMotiv is already conducting open experiments in that arena.
