# 察介
評介之用、達、效也。
## 用
- 釋前察用→用
- WCAG 2.1 達合→用
- 流之效→用
- 表設→用
- 啟發評既介→用
## 入
- **必**：所察之介（URL、原型、源碼）
- **必**：標用述（職、技、境）
- **可**：研果（訪、問、析）
- **可**：WCAG 標（A、AA、AAA）
- **可**：所察之流
- **可**：助技（讀屏、開關）
## 行
### 一：啟發評（Nielsen 十則）
逐則察介：
| # | 則 | 問 |
|---|---|---|
| 1 | **狀顯** | 系恆告用所事乎？|
| 2 | **介合實** | 用熟語熟念乎？|
| 3 | **用控自由** | 易撤、復、退乎？|

各則評重：
| 級 | 述 |
|---|---|
| 0 | 非問題 |
| 1 | 飾 — 暇修 |
| 2 | 微 — 低先 |
| 3 | 大 — 必修 |
| 4 | 災 — 釋前必修 |
```markdown
## Heuristic Evaluation Findings
| # | Heuristic | Severity | Finding | Location |
|---|-----------|----------|---------|----------|
| 1 | System status | 3 | No loading indicator during data fetch — users click repeatedly | Dashboard page |
| 3 | User control | 2 | No undo for item deletion — only a confirmation dialog | Item list |
| 5 | Error prevention | 3 | Date field accepts invalid dates (Feb 30) | Booking form |
| 9 | Error recovery | 4 | Form submission error clears all fields | Registration |
```
得：十則皆評，各有具體發現與重級。
敗：時迫→重 1、3、5、9。
### 二：達察（WCAG 2.1）
#### 可知
- [ ] **1.1.1 非文容**：圖皆有 alt（飾圖 `alt=""`）
- [ ] **1.3.1 訊關**：用語意 HTML
- [ ] **1.3.2 序意**：DOM 序合視序
- [ ] **1.4.1 色用**：色非唯傳訊
- [ ] **1.4.3 對比**：文 ≥ 4.5:1（常）、≥ 3:1（大）
- [ ] **1.4.4 縮文**：可縮 200% 不失功
- [ ] **1.4.11 非文對**：UI 元 ≥ 3:1
- [ ] **1.4.12 文距**：增距仍可用
#### 可操
- [ ] **2.1.1 鍵**：諸功皆鍵可操
- [ ] **2.1.2 無鍵困**：焦不困
- [ ] **2.4.1 跳鏈**：有跳導鏈
- [ ] **2.4.3 焦序**：Tab 序合理
- [ ] **2.4.7 焦顯**：焦印明顯
- [ ] **2.4.11 焦不蔽**：焦元不藏
- [ ] **2.5.5 標尺**：互動 ≥ 24x24px
#### 可解
- [ ] **3.1.1 頁語**：`<html>` 設 `lang`
- [ ] **3.2.1 焦時**：焦不引意外
- [ ] **3.2.2 入時**：入不引意外
- [ ] **3.3.1 誤識**：誤明述於文
- [ ] **3.3.2 標令**：表入有顯標
- [ ] **3.3.3 誤建**：誤訊建修法
#### 健
- [ ] **4.1.1 解析**：HTML 有效
- [ ] **4.1.2 名色值**：自定元有 ARIA
- [ ] **4.1.3 狀訊**：動容變宣告
得：WCAG 2.1 AA 系察、各條過/敗。
敗：先用 axe-core、Lighthouse 自動掃，後人評需判者。
### 三：鍵與讀屏察
#### 鍵導測
僅用 Tab、Shift+Tab、Enter、Space、箭、Esc：
```markdown
## Keyboard Navigation Audit
| Task | Completable? | Issues |
|------|-------------|--------|
| Navigate to main content | Yes — skip link works | None |
| Open dropdown menu | Yes | Arrow keys don't work within menu |
| Submit a form | Yes | Tab order skips the submit button |
| Close a modal | No | Escape doesn't close, no visible close button in tab order |
| Use date picker | No | Custom date picker not keyboard accessible |
```
#### 讀屏測
NVDA、VoiceOver、TalkBack 測：
```markdown
## Screen Reader Audit
| Element | Announced As | Expected | Issue |
|---------|-------------|----------|-------|
| Logo link | "link, image" | "Home, link" | Missing alt text on logo |
| Search input | "edit, search" | "Search products, edit" | Missing label association |
| Nav menu | "navigation, main" | Correct | None |
| Error message | (not announced) | "Error: email is required" | Missing live region |
| Loading spinner | (not announced) | "Loading, please wait" | Missing aria-live or role="status" |
```
得：全流以鍵獨、讀屏皆測。
敗：無讀屏→察 ARIA 與語意 HTML 為代。
### 四：流析
繪要流：
```markdown
## User Flow: Complete a Purchase
### Steps
1. Browse products → 2. View product → 3. Add to cart → 4. View cart →
5. Enter shipping → 6. Enter payment → 7. Review order → 8. Confirm
```
得：要流繪、摩擦點識別評級。
敗：無分析→按複雜與步數評。
### 五：認負察
- [ ] **訊密**：屏訊量適乎？
- [ ] **漸顯**：複訊漸顯乎？
- [ ] **塊**：相關視覺成組乎？
- [ ] **識勝憶**：見而非憶乎？
- [ ] **一致式**：同務同式乎？
- [ ] **決疲**：選過多乎？
- [ ] **工憶**：跨步需憶乎？
得：認負察、過載/不足區明。
敗：難客評→「眯測」（眯眼察結構顯否）。
### 六：表用察
各表：
- [ ] **標**：每入有顯關標
- [ ] **占文**：僅作例非標
- [ ] **入型**：HTML 入型正
- [ ] **驗時**：失焦或提交時誤
- [ ] **誤訊**：具非泛
- [ ] **必欄**：明標
- [ ] **欄組**：相關視覺組
- [ ] **自完**：`autocomplete` 設
- [ ] **Tab 序**：合視覺
- [ ] **多步表**：進度顯
- [ ] **持**：離返保
得：每表察、具體問題錄。
敗：表多→重高量者（註冊、結算、聯）。
### 七：書察報
```markdown
## UX/UI Review Report
### Executive Summary
[2-3 sentences]
### Top 5 Improvements (Prioritised)
1. **[Issue]** — Severity: [N] — [Specific recommendation]
```
得：察給優先可行建、附重級。
敗：問題過多→分「必修」（3-4）「宜修」（1-2）。
## 驗
- [ ] 十則皆評
- [ ] WCAG 2.1 至少 1.1.1、1.4.3、2.1.1、2.4.7、3.3.1、4.1.2 察
- [ ] 鍵導要流測
- [ ] 讀屏測（或 ARIA/語意 HTML 代）
- [ ] 至少一要流析摩擦
- [ ] 認負察
- [ ] 表用察
- [ ] 發現按重排可行建
## 忌
- **混 UX 與視設**：UX 為何運、視為何貌。美而 UX 劣可有
- **僅測順路**：誤、空、載、邊例為 UX 問題藏處
- **忽真機**：瀏覽器代之。真機觸、性、視口問題
- **達為後思**：晚發貴修。早續察
- **私好為 UX 反**：「吾偏好…」非 UX 反。引則、研、規
