If you read the article, they have 2 signals, one corresponding to what you're imagining your right hand doing, one to what your left is doing.

With this you have turn left, turn right, and both together is turn up.

To really fly it you need another control for speed. (They just made the speed constant.)

From what I know of existing EEG technology, the news here is left-right signaling, rather than simple on/off.

Fascinating and cool as hell, but really limited for HCI applications.
