The University of Florida held a drone race Friday, an unremarkable event except for one thing: the pilots used mind control to steer.

A brain-computer interface, which measures the brain’s electrical signals, allowed the students to guide the drones ... slowly through a short race, according to Quartz.com. BCIs are in the early stages so the controls aren’t as responsive as a handheld controller. But Juan Gilbert, a computer science professor at the University of Florida, said the simple race could lead to much bigger things.
