Whatever you do, don't think about getting hit in the face by a helicopter...
It's a Parrot ArDrone quadrotor. The frame is made of foam which encloses the rotors and the motors automatically cut off if they sense the blades are obstructed. Being hit by one is like being bumped with a bit of polystyrene.
(HN is so pedantic)

Seven dead astronauts taught me to distrust intuition about foam.
How many directions can EEG control. If this is just up and down based on your level of concentration, it is relatively useless. However, if it maps all 6 directions, it is pretty impressive.
the articles say 4 directions, but I'm going to assume that's because it's what they've been able to find clear enough patterns to map actions to. If they thought up a few more, ex "think about kicking your left leg" to move forwards, it could probably work. The leader talked about using wheelchairs and prosthetic limbs.

I wonder how many "channels" can be worked out? 2? 20? 2,000? 2,000,000? Anyone have any background on this? It's fascinating to think of the complexity of a machine that could be controlled, when compared to the inherent limitations of pedals, wheels, switches and the like.
It is highly unlikely that an EEG BCI will ever replace any normal task, as the performance relative to any reliable motor movement for direct control is terrible. For instance, if you have an eye tracker, you can reliably out perform the best BCI. It is really aimed at severely paralyzed people who don't have any other means of communication. The idea is undoubtedly cool and compelling, but the practicality of BCI for healthy subject use is very limited.

Google Glass and the Oculus Rift are very interesting for us, since it puts technology right on the spot where we need to acquire signals for brain-computer interfaces. FYI, there was a successful crowd-source campaign by InteraXon for an acceptable EEG headset [1]. This is the first headset that I can imagine being worn in public spaces. In five years we can potentially see brain-computer interfaces for consumers. I…
Awesome answer thanks! Do you think EEG can ever replace a keyboard and mouse?

No, not without some radical new insights :). But, why replace them? If you need something to replace them, probably you have a different need (e.g. hands-free, private communication, or expressing something that is hard to do consciously, like the level of pain, tiredness of familiarity of a face). Perhaps EEG can be used to fulfill that need instead.
Also replacing the keyboard is a worthwhile goal. A lot of people get RSI, and I think even at something fast like 100 wps our brain to computer "bandwidth" is pretty slow. (And typing fast takes a lot of practice)
