Use an electrode-laden helmet to detect brain-activity and graphically project it on the screen. Build a game around that which is similar to Guitar Hero or DDR.
Eventually, subliminal messages could be injected into the game, and the most receptive brain-pattern be used to get a high-score so that the person will become more suceptible to subversion...-- jong-scx, Sep 05 2006 A much cooler application for mind rhythm... what have you. http://www.neuroson...h/bgm-kurzweil.html [daseva, Sep 05 2006] Biofeedback computer games exist. They're usually of the "make this balloon float up in the air" variety, though, pretty easy. It takes a while to change your brain waves, so quick reactions are out of the question. It's still fun to learn to move a part of your body that you didn't know you could deliberately move!
(-) for the *use* unnecessary and technically bogus *a* introduction of "subliminal messages" *spellchecker* into an invention that has nothing to do with them.-- jutta, Sep 05 2006 To be fair, [jutta], I think the main point of the idea is the subliminal messaging, and the biofeedback game is a novel way of delivering it.
However, I think the idea does need more explanation of how the messages are delivered, and (perhaps more difficult) how receptivity is going to be detected or measured.-- pertinax, Sep 05 2006 random, halfbakery
