'Mind Gaming' Could Enter Market This Year
An anonymous reader writes "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."
I did a final project on the limits of EEG (electroencephalography, or getting-signals-using-electrodes-on-scalp, which is what this is) for a neurotechnology seminar last semester, and compared my findings to the claims made by Emotiv. The result: some of the things they claim this device can do are actually impossible and always will be, and others are extremely unlikely unless they've made some seriously groundbreaking discoveries. (Mediocre two-dimensional movement, for example, has been generated by EEG, but it'd be impossible with their headset unless they have some sick new algorithms.) The professor of the same course actually met with the president of Emotiv, who failed to demonstrate that the device could do anything.
Last I checked, their marketing videos are ridiculously flashy while showing no real control capability. My belief: EEG headsets like these, at best, will be controllable only by facial muscles (which completely overshadow the electrical potential generated by the brain) and by alpha rhythm amplitude, a very slow control signal demonstrated in "BrainBall", which was posted to slashdot some time earlier. At worst these headsets will be near-worthless devices, their sales supported entirely by false promises and media hype.
