Out of curiosity, is there a button that's held while rotating the stick to rotate? The stick looks directional, so it wouldn't make sense to just rotate it and keep it rotated...
My understanding is that when you rotate the stick, the angle controls the rotational (yaw) speed of the Volcopter (in other words, you hold the stick straight, it'll keep looking in a fixed direction, say north. Now if you twist the stick a few degrees, it'll slowly rotate in that direction (and keep rotating as long as you hold it twisted). If you twist it more, it'll rotate faster. If you let go (untwist), it'll stop rotating and maintain that heading.)
You can see this in this video of the first manned flight a year ago, at around 2:26.
You can also nicely see the thumb controlled ascent/descent switch at the beginning. Controls look super intuitive.
I can understand such motivation, but aviation is extremely heavily regulated area. I am not sure whether non-standard controls would even be allowed, though. While driver's license is granted for demonstration of rather basic ability to handle a vehicle, even non-commercial pilot's license (which I do not have, so) is granted for demonstrating substantial ability to control an aircraft and number of hours clocked. Enough hours that different controls could seem an obstacle.
If it was about new concept self-driving car with manual controls on joystick rather pedals and wheel, I would have my doubts about its marketability also.

Good point, regulation is a huge issue.
It is my understanding, though, that FAA and EASA are moving away from regulation that is very prescriptive in exactly how to achieve something (which would indeed make it hard to introduce an entirely new control concept) towards regulation that prescribes more what needs to be achieved (controllability, safety, etc.), under the heading of "performance-based certification".
Also, it appears regulators in Germany are somewhat positively disposed towards this, and even considering to establish a new category of aircraft with distinct certification requirements and airmen licensing requirements.
I mean, in fixed wings, you have to demonstrate a certain number of take-offs and landing, which makes perfect sense, but it's not really transferable to this aircraft:
ok, you sit in a Volocopter and then press the switch up with your thumb for take-off for a few seconds, then hold it fully down until touchdown (automatically slowed down when ground proximity is detected), then repeat a few times (up, down), and get your license... :-)
* rotate to rotate the craft (replacing rudder)
* move forward/backwards/sideways to move (translate) the craft (replacing cyclic)
* operate simple switch on top to ascent/descent (replacing collective and throttle)
