Individual skill

microinteractions

Design the small details -- triggers, rules, feedback, loops and modes -- that separate good products from great ones. Use when the user mentions "microinteraction", "button feedback", "loading state", "toggle design", "animation detail", "state transitions", "input feedback", "the interface feels dead", "make the UI feel responsive", or "add polish to interactions". Also trigger when designing form-validation responses, progress indicators, confirmation dialogs, or any element where the user expects immediate feedback. Covers trigger design, state rules, feedback mechanisms, and progressive loops. For overall UI polish, see refactoring-ui. For affordance design, see design-everyday-things.

# Microinteractions Framework

Design the tiny, contained product moments users touch every day -- toggles, password fields, loading indicators, pull-to-refresh, like buttons. Based on Dan Saffer's four-part structure (Trigger, Rules, Feedback, Loops & Modes), this framework turns invisible details into the polish that separates forgettable products from beloved ones.

## Core Principle

**The difference between a product you tolerate and a product you love is almost always in the microinteractions.** A microinteraction is a contained moment built around a single use case -- changing a setting, syncing data, picking a password -- so small that users rarely think about it consciously, but they feel it. Every microinteraction follows the same four-part structure: a Trigger initiates it, Rules determine what happens, Feedback shows what is happening, and Loops & Modes define its long-term behavior.

## Scoring

**Goal: 10/10.** Score by how many of the 8 Quick Diagnostic rows the microinteraction passes — `score = round(passed / 8 × 10)`, then read the band:
- **9-10** = passes all 8 rows: deliberate discoverable trigger with visible states, simple predictable rules, sub-100ms feedback scaled to event significance, evolves over time, mode-free or mode-visible, learnable without help.
- **5-6** = 4-5 rows pass: it works but has a generic feel -- e.g. feedback exists but is uniform, or the trigger lacks distinct states.
- **<=3** = 2 or fewer rows pass: missing feedback, invisible triggers, or hidden modes that break trust.
