Ui Ux And Feedback

name: ui-ux-and-feedback
description: Use when designing, auditing, or generating a HUD, menu system, or feedback vocabulary for any genre — information hierarchy, diegetic vs. non-diegetic classification, cognitive load budgeting, feedback channel design, menu flow, input modality, and accessibility. Also use to diagnose a UI that is cluttered, that players ignore, that confuses state, or where players miss critical information.

# UI/UX & Information Design

How to give players exactly the information they need to decide right now — no more, no less — and communicate every game-state change through channels they can read under pressure.

> **Tier:** universal craft (→ `gamestack-core`). Applies to every genre and every game. The feel of individual UI elements (squash on button press, easing on transition) lives in `game-feel-and-juice`, which cites *up* to this skill; this skill owns the information architecture and UX layer.

## When to use this

- Classifying each HUD element on the Fagerholt axes (diegetic / non-diegetic / spatial / meta) and writing a HUD spec contract
- Auditing why players miss critical state, pause constantly to check info, or describe the UI as cluttered or confusing
- Designing or reviewing the feedback vocabulary (visual / audio / haptic / camera) for a mechanic set
- Specifying menu depth, input modality, navigation flow, and settings infrastructure
- Generating a reflowable, data-driven HUD spec from a mechanic inventory

## Scope

This skill owns **information architecture and UX** — what to show, when, in what form, and how to communicate state change. Adjacent concerns live in sibling skills:

- The *feel* of UI elements — button squish, easing curves, transition timing, UI juice → `game-feel-and-juice` (owns the feedback layer; this skill sets what to communicate, that skill sets how good it feels)
- Visual contrast, signal color, silhouette, and legibility at the pixel level → `art-direction-and-readability`
- Tutorial and first-play onboarding sequencing (the *teaching* layer, not the HUD layer) → `onboarding-and-teaching`
- Reward structure, flow, and motivation theory underneath the feedback → `game-design-fundamentals`
- Session rhythm and how menu transitions pace the experience → `pacing-and-the-player-journey`

## How the pieces fit

- **`GUIDE.md`** — the cited *why*, in five sub-domains: the Fagerholt–Lorentzon four-type taxonomy (diegetic / non-diegetic / spatial / meta); information hierarchy and cognitive load (Sweller, Hodent); feedback and game-state communication; menu and navigation flow / input modality; accessibility-adjacent UX. Each rule carries an exemplar + source, a **test-for** criterion, the named failure mode, and the **procedural / headless implication**.
- **`CHECKLIST.md`** — Do/Don't + machine-checkable **Test-for** criteria, grouped by sub-domain. Written to be enforced as validators in a generation loop.

## The one idea to anchor on

> **The HUD's only job is to give the player what they need to decide right now.** Every element that isn't serving the current decision is extraneous cognitive load — a tax the player pays with attention and performance (Sweller 1988; Hodent 2017). Show Tier-1 state (health, ammo, objective) permanently at the periphery; surface Tier-2 state on context; hide Tier-3 state in menus. Diegetic where the world can carry it plausibly; non-diegetic where it can't; never pure-diegetic for data that changes faster than world-object animation can track.

Start with `GUIDE.md`, then apply `CHECKLIST.md`.
