Here is a video from CEBiT featuring a couple people hooked up to a computer via some kind of brain interface. I'd had to say they probably don't have any implanted electrodes and the helmet that they are wearing picks up the brain activity. Both people are playing a game of pong against each other via the brain interface. There isn't really much to see other than the two guys sitting there and the pong paddles moving up and down on the screen. I've seen things like this before usually for people who are disabled but nothing that you could really go out and buy in the store. Coming any time soon to a store near you? I doubt it.
