I didn’t ignore what you said. I apologize if it came off that way.
When I was learning to drive back in the 80s, that was literally a thing I focused on: how to make changes to the radio station without taking my eyes off the road.
When I touch the knob, jokes aside, when I touch the knob there is a touching sense, what is called a tactile sensation that lets me know that I have touched a thing and this is the shape and feel of the thing I touched.
There is no tactile sensation that can differentiate between one button on a screen and another.
I’ll give another example in hopes it clarifies: a couple years back Apple replaced a physical Escape key, the top left key, with a Touch Bar. I use an editor that requires hitting the escape key a hundred or two times a day.
I could never tell if I hit that escape key because I was just tapping an area on the Touch Bar with no tactile indication that I had touched or tapped or pressed the thing.
