## 매 한 줄
|
||||
> **"매 humans + computers — interface as cognitive contract."** Sutherland Sketchpad (1963) → Engelbart "Mother of All Demos" (1968) → Xerox PARC GUI → modern multimodal (touch, voice, gesture, AR/VR, BCI). 매 2026 inflection — 매 LLM as interface (chat, agent, voice), 매 ambient computing, 매 brain-computer interfaces (Neuralink, Synchron).
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 Foundational principles
|
||||
- **Affordance** (Gibson/Norman): 매 perceived action possibilities.
|
||||
- **Feedback**: 매 action → immediate response (≤100ms feels instant).
|
||||
- **Discoverability**: 매 features 의 findable.
|
||||
- **Consistency**: 매 platform conventions 의 respect.
|
||||
- **Error tolerance**: 매 undo, 매 confirmation, 매 graceful degradation.
|
||||
|
||||
### 매 Cognitive load (Sweller)
|
||||
- **Intrinsic** — 매 task 의 inherent complexity.
|
||||
- **Extraneous** — 매 poor design 의 added burden.
|
||||
- **Germane** — 매 schema construction.
|
||||
|
||||
### 매 Modalities (2026)
|
||||
- **Touch / pointer** — 매 still dominant.
|
||||
- **Voice** — 매 LLM 의 robust (Whisper, Voxtral).
|
||||
- **Multimodal LLM** — 매 image + text + voice (Claude Opus 4.7, GPT-5).
|
||||
- **AR/VR** — 매 Vision Pro 2, Meta Quest 4.
|
||||
- **BCI** — 매 emerging (Neuralink N1, Synchron Stentrode).
|
||||
|
||||
### 매 응용
|
||||
1. Adaptive UI — 매 LLM-driven personalization.
|
||||
2. Accessibility — 매 WCAG 3.0, 매 screen reader, 매 alt-text auto-generation.
|
||||
3. Voice-first products — 매 in-car, 매 smart home, 매 wearable.
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### Fitts's Law calculator
|
||||
```typescript
|
||||
// time = a + b * log2(distance / width + 1)
|
||||
function fittsTime(distancePx: number, targetWidthPx: number,
|
||||
a = 50, b = 150): number {
|
||||
return a + b * Math.log2(distancePx / targetWidthPx + 1);
|
||||
}
|
||||
// 매 button placement decision: minimize time
|
||||
```
|
||||
|
||||
### Optimistic UI
|
||||
```typescript
|
||||
// React — 매 perceived latency reduction
|
||||
function useOptimisticToggle(initial: boolean, save: (v: boolean) => Promise<void>) {
|
||||
const [value, setValue] = useState(initial);
|
||||
const toggle = async () => {
|
||||
const next = !value;
|
||||
setValue(next); // 매 instant feedback
|
||||
try { await save(next); }
|
||||
catch { setValue(!next); /* revert */ }
|
||||
};
|
||||
return [value, toggle] as const;
|
||||
}
|
||||
```
|
||||
|
||||
### Debounced search (cognitive flow)
|
||||
```typescript
|
||||
import { useEffect, useState } from 'react';
|
||||
|
||||
function useDebouncedValue<T>(value: T, delayMs: number): T {
|
||||
const [debounced, setDebounced] = useState(value);
|
||||
useEffect(() => {
|
||||
const t = setTimeout(() => setDebounced(value), delayMs);
|
||||
return () => clearTimeout(t);
|
||||
}, [value, delayMs]);
|
||||
return debounced;
|
||||
}
|
||||
// 매 300ms — 매 typing pause 의 natural query trigger
|
||||
```
|
||||
|
||||
### Accessible button
|
||||
```tsx
|
||||
// WCAG 2.2 AA
|
||||
<button
|
||||
onClick={handleClick}
|
||||
aria-label="Delete item"
|
||||
aria-describedby="delete-help"
|
||||
disabled={isLoading}
|
||||
className="min-h-[44px] min-w-[44px]" // 매 touch target
|
||||
>
|
||||
{isLoading ? <Spinner aria-hidden /> : <TrashIcon aria-hidden />}
|
||||
<span id="delete-help" className="sr-only">
|
||||
매 permanently delete this item
|
||||
</span>
|
||||
</button>
|
||||
```
|
||||
|
||||
### LLM voice interface
|
||||
```typescript
|
||||
// 매 speech-to-LLM-to-speech
|
||||
import Anthropic from '@anthropic-ai/sdk';
|
||||
|
||||
async function voiceTurn(audioBlob: Blob): Promise<Blob> {
|
||||
const transcript = await transcribe(audioBlob); // Whisper-v4
|
||||
const client = new Anthropic();
|
||||
const reply = await client.messages.create({
|
||||
model: 'claude-opus-4-7',
|
||||
max_tokens: 512,
|
||||
messages: [{ role: 'user', content: transcript }],
|
||||
});
|
||||
return await synthesize(reply.content[0].text); // ElevenLabs / OpenAI TTS
|
||||
}
|
||||
```
|
||||
|
||||
### Eye-tracking heatmap (Vision Pro)
|
||||
```swift
|
||||
// SwiftUI + visionOS
|
||||
import SwiftUI
|
||||
import RealityKit
|
||||
|
||||
struct GazeAwareView: View {
|
||||
@State private var gazeTarget: Entity?
|
||||
var body: some View {
|
||||
RealityView { content in
|
||||
// ARKit eye tracking
|
||||
content.add(makeButton(on: .gaze) { entity in
|
||||
gazeTarget = entity
|
||||
})
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Skeleton loader (perceived performance)
|
||||
```tsx
|
||||
// 매 content shape preview while loading
|
||||
function ArticleSkeleton() {
|
||||
return (
|
||||
<div className="animate-pulse">
|
||||
<div className="h-6 bg-gray-200 rounded w-3/4 mb-4" />
|
||||
<div className="h-4 bg-gray-200 rounded mb-2" />
|
||||
<div className="h-4 bg-gray-200 rounded w-5/6" />
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| Latency-sensitive UI | Optimistic update + skeleton |
|
||||
| Form-heavy flow | Inline validation + autosave |
|
||||
| Voice product | LLM round-trip <800ms target |
|
||||
| Accessibility | WCAG 2.2 AA minimum, AAA 권장 |
|
||||
| Multimodal | LLM가 매 modality routing |
|
||||
|
||||
**기본값**: 매 100ms feedback, 매 1s task completion, 매 10s context preserve (Nielsen 1993, 매 still holds).

## 🤖 LLM 활용
|
||||
**언제**: copywriting, alt-text generation, A11y review, conversational UI design.
|
||||
**언제 X**: 매 user research synthesis (real interviews 의 irreplaceable).
|
||||
|
||||
## ❌ 안티패턴
|
||||
- **Dark patterns**: 매 manipulative consent, 매 hidden costs.
|
||||
- **Touch target <44px**: 매 fat-finger errors.
|
||||
- **Loading without feedback**: 매 user 의 abandons after 3s.
|
||||
- **Voice-only critical action**: 매 destructive action 의 confirmation 의 X.
|

## 🧪 검증 / 중복
|
||||
- Verified (Norman "Design of Everyday Things", Nielsen Norman Group, WCAG 2.2 W3C).
