Researchers at the University of Minnesota have done away with all that tedious joystick work by developing a mind-controlled quadcopter. It may seem like the top item of next year's Christmas list, but it also serves a very practical purpose. Using a skullcap fitted with a Brain Computer Interface (BCI), the University's College of Science and Engineering hopes to develop ways for people suffering from paralysis or neurodegenerative diseases to employ thought to control wheelchairs and other devices.
