The scientists, from MIT's Computer Science and Artificial Intelligence Laboratory and Boston University, created a feedback system that lets people correct robot mistakes instantly with nothing more than their brains. Using data from an electroencephalography (EEG) monitor that records brain activity, the system can detect if a person notices an error as a robot performs an object-sorting task. When a person's brain notices that a mistake has been made or is about to be made, it creates brain signals called "error-related potentials". While the system currently handles relatively simple choice activities, MIT scientists believe that they could one day control robots in much more intuitive ways.
