When I was a wee lad, probably 1980 or so, I was a regular at a market testing group for video games. It was usually just whatever new game was coming soon, but once it was a headband that you wore, with electrodes. It would control your Atari 2600 "by thought". I remember playing River Raider with it at the testing, you could go left and right and fire. I don't think it actually read your brain activity, I think it was more muscle control dressed up, but it sorta worked. Edit- Link to some info on the device. It did in fact work by muscle activity. http://www.atarimuseum.com/videogames/consoles/2600/mindlink.html http://www.atarimuseum.com/videogames/consoles/2600/mindlink...
