University of Minnesota biomedical engineering professor Bin He has been working on a brain-computer interface that allows people to steer robots with their thoughts. In the video above, young students manipulate a flying machine right, left, up, and down using only their minds (e.g. think about making a fist with your right hand to make it turn right).
This kind of technology might one day allow people with limited mobility to control artificial limbs, wheelchairs, and other medical devices. Not long after that it will be exploited by SkyMall companies selling perfectly healthy Americans beer mugs they can think over to themselves on the couch.
