Microinteractions for buttons use timing, easing, and state transitions (hover, focus, active, loading) to provide clear visual feedback. Define each state's duration and easing curve to balance perceived performance with accessibility, ensuring feedback remains noticeable for all users.

Accessible animations respect motion preferences, use sufficient contrast and duration for clarity, and avoid flashing. Performance-optimized animations leverage GPU acceleration, reduce repaints, and keep frame rates smooth—critical for mobile and web apps where timing and easing directly affect both experience and usability.

Yes. Microinteraction audits examine button states, form feedback, loading indicators, notifications, and page transitions against timing standards, easing consistency, state clarity, and accessibility requirements, identifying gaps in feedback intentionality across web and mobile interfaces.

Define a timing system—duration for each interaction type (form feedback, notifications)—and select easing curves that match intent: ease-out for entrances, ease-in for exits. Apply consistently to inputs, cards, modals, and notifications so users develop reliable expectations for interaction response.

Perceived performance uses timing and easing to make actions feel faster or more responsive—loading spinners, state transitions—without changing actual speed. Actual performance optimizes rendering. Together, they create smooth, intentional feedback that reduces user friction and improves confidence in the interface.

Yes. Button states, form feedback, loading indicators, and page transitions follow the same principles—timing, easing, state changes, accessibility—across platforms. Mobile requires attention to touch feedback and reduced animation duration; web benefits from hover states. Both need performance optimization and accessible motion.
