The power of the mind may be the next big thing in video games, and it may come soon.

Emotiv says its mind-control headsets will be on shelves later this year, along with a host of novel biofeedback games developed by its partners. Several other companies–including EmSense in Monterey, California; NeuroSky in San Jose, California; and Hitachi in Tokyo–are also developing technology to detect players´ brainwaves and use them in next-gen video games.

The technology uses a combination of EEGs (which reveal alpha waves that signify calmness), EMGs (which measure muscle movement), and ECGs and GSR (which measure heart rate and sweating). Near infrared spectroscopy, which monitors changes in blood oxygenation, could also be incorporated since it overcomes some of the interference problems with EEGs.
