Re: Hang on a moment...
Yup, UI design is not just about computer interfaces.
Without prior knowledge, I would have done exactly the same thing, because t'wrong 'ole has that circle around it making it look even more like a target.
I think it's because it looks like a pivoting part, so it's a surface phlange for the internal pivot, but that very plain hole adjacent does not look functional at all.
So the surface "decoration" should indeed look different and preferably, the holes have different dimensions and/or shapes to prevent accidents happening.
So many engineering accidents have happened due to ambiguous controls, and planes downed multiple times. You think that designers would have a better handle on this kind of thing by now.
