Big knobs for varying things. Push them to toggle things. Important shortcuts — the aforementioned defogger being one of them — on the real buttons inbetween.
Physically rotate the whole unit to control direction and a physical flow control switch for every vent to allow per-passenger comfort.
I love the design, but I personally find it less intuitive than conventional hvac controls like this, because Audi had to squeeze things into 3 circular LCDs.
While I am not a BMW fan, they got the interfaces almost close to perfect with their MINI Countryman cars. The screen is a touchscreen one, but, touchscreen is optional as there is a physical idrive controller, with shortcuts, and it works with carplay as well. All important stuff, defroster/AC/seat heaters are physical buttons! I love it.

Industrial design bliss.
