Engineers at NeuroSky Inc. have big plans for brain wave-reading toys and video games. They say the simple Darth Vader game -- a relatively crude biofeedback device cloaked in gimmicky garb -- portends the coming of more sophisticated devices that could revolutionize the way people play.
Technology from NeuroSky and other startups could make video games more mentally stimulating and realistic. It could even enable players to control video game characters or avatars in virtual worlds with nothing but their thoughts.
Adding biofeedback to "Tiger Woods PGA Tour," for instance, could mean that only those players who muster Zen-like concentration could nail a putt. In the popular first-person shooter "Grand Theft Auto," players who become nervous or frightened would have worse aim than those who remain relaxed and focused.
