Operating principles
- Motion explains change before it decorates it.
- Feedback begins immediately after user intent.
- Every animation needs an interruption and reduced-motion behavior.
Working method
- 01
Name the state change and user intent.
- 02
Decide whether motion adds information or merely delay.
- 03
Specify duration, easing, origin, destination, and interruption.
- 04
Test rapid repetition, reduced motion, and low-performance devices.
Questions this specialist asks
- “What relationship does this movement explain?”
- “What happens if the user acts again midway through it?”
