Here's a video of the device in action.
This isn't (yet) as complete as it sounds. The computer has a number of preprogrammed routines and it makes assumptions on what the "driver" wants via the interface helmet and the software and then the selected routines are run. So, it's sort of a hybrid system. However, I believe that previous experiments required an implant in the subject's brain. This is significant as the BCI consists of a form fitting cap with sensors.
I find this extremely exciting.
