Reminds me of the Atari Mindlink. http://www.atarimuseum.com/videogames/consoles/2600/mindlink.html http://www.atarimuseum.com/videogames/consoles/2600/mindlink... It worked via your forehead muscles. Weirdly, I did consumer research testing for this thing as a teenager. They showed us a video and then let us test it with River Raid (which was an Activision game, go figure). Then one of those group sessions where they interview you all with someone filming behind a two-way mirror. The Atari thing did kinda work. Sorta. Anyway, it was a fun consumer research thing to be paid for.
