The best interaction work usually feels obvious in retrospect.
The user moves, the interface responds, and the transition between states makes the product easier to understand.
The principle
Motion should reinforce structure.
That usually means:
- transitions should explain where the user is going
- hover states should make affordances clearer
- animations should avoid slowing down common tasks
What I watch for
When interaction starts to feel wrong, it is often because:
- the timing is too dramatic for the task
- too many elements compete for attention
- the animation looks nice but does not improve orientation
The strongest motion systems are usually the quiet ones. They guide attention, create rhythm, and help products feel more considered without demanding to be noticed every second.
