In an adapted version of the Harry Potter video game, players lift boulders and throw lightning bolts using only their minds. Just as physical movement changed the interface of gaming with Nintendo’s Wii, the power of the mind may be the next big thing in video games.
And it may come soon. Emotiv, a company based in San Francisco, 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 is based on medical technology that has been around for decades. Using 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), developers hope to create a picture of a player´s mental and physical state. Near infrared spectroscopy (NIRS), which monitors changes in blood oxygenation, could also be incorporated since it overcomes some of the interference problems with EEGs.
