Brain-computer interfaces have been popping up left and right lately, but the latest system from Germany's Technical University of Braunschweig, might be the silliest one we've seen so far. While the system doesn't involve the careful placement of electrodes, it does require you to don a large metal helmet fitted with sensors, which can even detect brain activity through hair -- and makes you look like Magneto on a bad day. The system is solid enough to allow test subjects to control an RC car and researchers say the tech is similarly applicable to wheelchairs and prosthetics. Yeah, that's great -- we'll stick with the dangerous neurosurgery implantation over this contraption, guys. Video after the break.
