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 put. In the popular action game “Grand Theft Auto,” players who become nervous or frightened would have worse aim than those who remain relaxed and focused.

NeuroSky’s prototype measures a person’s baseline brain-wave activity, including signals that relate to concentration, relaxation and anxiety. The technology ranks performance in each category on a scale of 1 to 100, and the numbers change as a person thinks about relaxing images, focuses intently, or gets kicked, interrupted or otherwise distracted.

We have seen some of these kind of interactive displays at some of the shows we have been to. It’s facinating to wonder how this technology will integrate itself into our lives. There are some bars that have using similar technology so far for a cool lighting effect.
