You select a file, press the button, and wait. The button changes its label. A small indicator appears beside the file. When the process finishes, the file remains where you can see it, with a clear indication that it is ready. The sequence sounds almost too ordinary to discuss, which is part of the achievement. You can follow what happened without composing an explanation for yourself.
An interface has a pace even when nothing in it is animated. It gives you things to notice in an order, asks you to choose, then tells you what followed from the choice. A dense panel can make a simple action feel like a careful inspection. A familiar control in a stable place can let you continue with very little ceremony. The experience comes from the transitions as much as from the individual screens.
It is useful to look at those transitions without the finished task in mind. Watch the moment after a button is pressed. Is there a visible response? Does the current item stay recognizable? Can you tell whether you are waiting for something or being asked to act again? These questions concern the experience on the surface. They can be considered before anyone makes a claim about how quickly the machinery underneath ought to work.
