This mind-power trick may seem far-fetched, like something from a late-night science fiction movie or the back of an old comic book. But several companies are bringing this technology to life with affordable headsets that determine a person’s state of mind.
With NeuroSky’s headset, people can manipulate real and digital objects
The gadgets translate brain waves into digital information and beam it wirelessly to computers or other devices.
So far the headsets are confined to mostly digital interfaces—videogames and movies whose plots can be altered with the mind—although in some cases real-world objects have been used, like a pair of catlike ears that move depending on a person’s mood.
