Better comparison would be another capsule for ISS missions, since the functionality is about the same. The obvious one being Soyuz capsule, the control dash area happens to be about the same size and looks more realistic to condense.

Starliner has a much more traditional interior design than the Dragon but both are intended to be flown completely automated, so the controls are somewhat redundant anyway.

Found an article on the controls:

I'm still puzzled on how they are going to operate those touch screens in high-G (emergency) situations. Fighter jets typically have force sensor sticks for which you don't need to lift or move your arm at all.

What exactly is an high-G manoeuvre for you? If i recall correctly the crew is suspected to ~2.5G shortly before Max-Q, and right now you have to fighter pilots sitting in the capsule, they probably won't bat an eye (okay, that's going to change with regular missions). They would probably see ~6-7 G on a inflight abort at Max-Q (someone did the math for the ground abort and calculated 3.5G for that, plus the ~2.5G during normal flight), but it would require superhuman reactions to control the capsule anyway, so it is done by the flight computer ->no interactions required.
The only situation where they could be required to use the touchscreens at high-G would be during reentry, but if the capsule is similar to the Souyz they would experience under 4G (and i am not sure if this G-number is reached while breaking or if it is the negative G they would feel when the chutes deployed).

It's not like the old Gemini/Mercury systems that reached 7G on both stages, you probably just had to pray that the rest of the rocket would function if something broke during launch.
nctnico:
IIRC one of the Gemini missions got a stuck manoeuvring thruster putting the space craft into a wild spin. Current technology is likely much better but things still can go wrong.
dr.diesel:
Anybody know what OS is running on the Dragon touchscreens?

SpaceX uses a lot of Linux from what I've heard, but the bottom menu row does look a bit custom Winish.   :horse:
