Well, maybe you’d like to control a helicopter with mind. I don’t know you. Maybe you’re into that kind of thing. Who am I to judge?

A University of Minnesota researcher has created a brain-computer interface that allows a person to move a 3-D helicopter on a screen using just her thoughts. A lab subject describes how she used the technology created by biomedical engineering professor Bin He to move the helicopter in a digital landscape by focusing on her right hand or left hand to light up electrodes. Ultimately Professor He hopes the technology could benefit stroke or paralysis victims.
