Five subjects, which the researchers specifically describe as ‘human’ in case you were wondering, were trained to move a cursor on a screen by imagining that they were squeezing one or both of their fists. They then used the same techniques to control first a virtual quadcopter and then a real one. All five participants were successful in making the robot fly in a chosen direction, including through rings.
While controlling toys with your mind might be cool, the researchers are really looking forward to using their technique to help paralyzed people control every day electronic objects. The key thing about this technology is that it’s completely non-invasive, meaning that it does not require any surgical implants. You do have to wear the funny electroencephalogram bonnet though.
You can see the a clip of the experiments below:
In case it isn’t clear from the video, the controller is facing away from the quadcopter. A camera mounted on the quadcopter gives the subject a first person view on his computer monitor.
