We may have seen the monkey controlling a robotic arm, but here it is in human trials with much more impressive results. Researchers were able to train the system by having the participant think about moving her arm. With several months of training, her motions were fluid and precise (see video below). Future improvements would make the system more tolerable to brain tissue and wireless, paving the way for those direct brain/machine interfaces we’ve imagined.
Still, it requires surgery. Gives new meaning to “you are the controller,” doesn’t it?
