Called 2ch, the sculpture is by artist Dmitry Morozov, an ambitious art project created to be a brain-to-brain interface. Via FastCoDesign:
In 2ch, the machine is not the end point for your thoughts, but the mediator to another person.
Maybe that sounds a lot like existing technologies—the telephone comes to mind! But what’s different about 2ch is that the machine uses an EEG reader—a skull-worn sensor that can measure the electricity in your brain—to measure your brainwaves, essentially reading your thoughts directly. Then two users can both wear headsets to connect to the machine at once, each trying to coax their half of the machine into working in tandem with the other, matching the same pitch, lining up a robotic arm at the same angle, or playing an abstract video in sync.
There’s no tutorial on how to think to make these things happen, however, so learning to communicate via your mind with someone else necessitates time. “It takes around two to three hours to get some clear result, but you feel changes even from the beginning,” says Morozov. “It’s good to be in mood to work with it, not very tired or irritated. But anger or any other strange state of mind could be fun, too.”
