After some digging, I can confirm that they appear to use the Emotiv headset like munin hints on. While I never got around to diving too deep into my Emotiv headset, the one thing I did notice is during my profile training, I wouldn't get precise results without forcing some sort of neuro-muscular response (pulling my head slightly back to move the block closer).
I noticed the person in the wheelchair showed control from at least the neck up, so I assume there was some use of muscles to get that sort of response out of the quadcopter. Thinking, without muscles, is actually really HARD! I couldn't get past training without some assistance, and that was with maybe 2-3 actions (imagine ~10 different actions with unique thoughts needed)
Its still amazing work, and I'm glad to see some research in the field and will definitely try to get a copy of their paper. I'd love to see the next step to be either controlling the wheelchair with some good response time, or to increase the number of actions possible.
