Interaction Design & UI Micro-Animations
Interaction design turns static screens into engaging, responsive user experiences. Designers demonstrate technical capability by crafting micro-interactions, configuring easing animation curves (200-300ms timing), designing interactive state feedback, and mapping gesture controls.

Design guide establishing standard timing parameters and feedback states for interactive components.
Frequently Asked Questions (Interaction Design & Micro-interactions)
What is the ideal duration for UI micro-interactions?
UI micro-interactions should last between 200ms and 300ms. Anything faster feels abrupt; anything slower than 400ms feels sluggish.
Why are easing curves (ease-in-out) used in UI animation instead of linear movement?
Physical objects in the real world accelerate and decelerate naturally. Linear animations feel robotic and unnatural to the human eye.
What is a feedback loop in interaction design?
A feedback loop provides instant visual, audio, or haptic confirmation that the system received a user input (e.g. a button changing state when pressed).
