You can just feel your way around. If all the buttons have the same shape, sure, you can’t, but they don’t have the same shape. For example, if one button has a little raised nub, like the F key in keyboards, you know immediately which button your finger is on.
This. I don’t need braille to know which button, it becomes muscle memory. A touch screen UI changes dynamically, so having muscle memory like for a physical momentary switch is impossible. And the tactile feedback is important too.
