How does Audi's virtual cockpit display work in the A7?

I've heard that the A7 has a unique virtual cockpit display. Can someone explain how it works and if it's easy to use while driving?

The virtual cockpit display in the Audi A7 is a fully digital instrument cluster that can be customized to show a variety of information such as navigation, audio, and vehicle status. It can be controlled using the steering wheel controls, voice commands, or the central touch display. I find it to be very intuitive and convenient while driving.
