# Flow State

## 매 한 줄
> **"매 challenge와 skill이 정확히 균형된 순간 시간이 사라진다"**. 매 Flow는 Csikszentmihalyi(1975)가 정의한 optimal experience — 매 자아 의식 사라짐, immediate feedback, intrinsic reward. 2026 game design, productivity tool, learning platform의 매 design target.

## 매 핵심

### 매 8 Conditions (Csikszentmihalyi)
1. **Clear goals**: 매 매 순간 무엇을 해야 하는지 명확
2. **Immediate feedback**: 매 action → result 즉시
3. **Skill-challenge balance**: 매 너무 쉬우면 boredom, 너무 어려우면 anxiety
4. **Action-awareness merge**: 매 doing = thinking
5. **Concentration**: 매 task에 완전 집중
6. **Sense of control**: 매 outcome 지배감
7. **Loss of self-consciousness**: 매 ego 사라짐
8. **Time distortion**: 매 5시간이 30분처럼

### 매 Flow Channel
- **Anxiety zone**: 매 challenge ≫ skill
- **Boredom zone**: 매 challenge ≪ skill
- **Flow channel**: 매 둘이 동반 상승 (스킬 ↑ → 도전 ↑)

### 매 응용
1. Game difficulty curves (Souls-like, rhythm games).
2. Coding flow (Pomodoro, focus mode).
3. Dynamic difficulty adjustment (Resident Evil 4 director AI).
4. Educational scaffolding (Duolingo adaptive).

## 💻 패턴

### Dynamic Difficulty Adjustment (Unity C#)
```csharp
public class FlowDifficulty : MonoBehaviour
{
    float playerSkill = 0.5f;  // 매 EMA estimate
    float currentDifficulty = 0.5f;
    
    void OnPlayerSuccess()
    {
        playerSkill = 0.9f * playerSkill + 0.1f * 1.0f;
        AdjustDifficulty();
    }
    
    void OnPlayerFail()
    {
        playerSkill = 0.9f * playerSkill + 0.1f * 0.0f;
        AdjustDifficulty();
    }
    
    void AdjustDifficulty()
    {
        // 매 keep difficulty slightly above skill (flow channel)
        currentDifficulty = Mathf.Clamp(playerSkill + 0.1f, 0.1f, 0.95f);
        ApplyDifficulty(currentDifficulty);
    }
}
```

### Focus Mode (VS Code extension)
```typescript
import * as vscode from 'vscode';

export function enterFlowMode() {
    vscode.workspace.getConfiguration().update('zenMode.fullScreen', true);
    vscode.workspace.getConfiguration().update('workbench.activityBar.visible', false);
    vscode.workspace.getConfiguration().update('editor.minimap.enabled', false);
    
    // 매 disable notifications
    vscode.commands.executeCommand('notifications.toggleDoNotDisturbMode');
    
    // 매 25min Pomodoro
    setTimeout(() => {
        vscode.window.showInformationMessage('매 flow check: 잠시 휴식?');
    }, 25 * 60 * 1000);
}
```

### Skill Tracking (Python EMA)
```python
class SkillTracker:
    def __init__(self, alpha=0.1):
        self.alpha = alpha
        self.skill = 0.5
    
    def update(self, success: bool):
        target = 1.0 if success else 0.0
        self.skill = (1 - self.alpha) * self.skill + self.alpha * target
    
    def in_flow_zone(self, difficulty: float) -> bool:
        # 매 difficulty 가 skill 의 ±15% 안에 있어야 flow
        return abs(difficulty - self.skill) < 0.15
```

### Immediate Feedback (Web)
```javascript
// 매 keystroke마다 syntax check (flow-friendly)
let timeoutId;
editor.on('change', () => {
    clearTimeout(timeoutId);
    timeoutId = setTimeout(() => {
        const errors = lint(editor.getValue());
        showInlineErrors(errors);  // 매 즉시 visual feedback
    }, 100);  // 매 debounce 100ms — 매 fast enough for flow
});
```

### Distraction Blocking (macOS Focus)
```bash
# 매 macOS Shortcuts CLI
shortcuts run "Focus: Do Not Disturb On"

# 매 hosts file block social
echo "0.0.0.0 twitter.com" | sudo tee -a /etc/hosts
echo "0.0.0.0 reddit.com" | sudo tee -a /etc/hosts
```

### Flow Telemetry (game)
```python
def log_session_flow(session):
    duration = session.end - session.start
    deaths = session.deaths
    completions = session.completions
    
    # 매 high engagement + moderate failure = flow
    if duration > timedelta(minutes=20) \
       and 0.3 < deaths / (deaths + completions) < 0.6:
        analytics.track("flow_session", session.user_id)
```

## 매 결정 기준
| 상황 | Design priority |
|---|---|
| Action game | Tight feedback loop, DDA |
| Strategy game | Clear goal, skill ceiling exposure |
| Learning app | Adaptive difficulty, immediate hint |
| Productivity tool | Distraction-free mode, focus timer |
| Casual game | Low anxiety, high accessibility |

**기본값**: 매 difficulty = skill + 10%, feedback < 200ms, distraction = 0.

## 🤖 LLM 활용
**언제**: 매 game design review, learning UX critique, productivity workflow 진단.
**언제 X**: 매 medical/clinical attention disorder context — flow state는 self-help framework, not therapy.

## ❌ 안티패턴
- **Forced flow**: 매 user를 trap (매 dark UX) → 매 burnout, churn.
- **Notification interrupt**: 매 push 매 5분 → 매 flow 진입 불가능.
- **Difficulty spike**: 매 sudden challenge → 매 anxiety zone 추락.
- **Reward without challenge**: 매 free progress → 매 boredom.

## 🧪 검증 / 중복

- Verified (Sweetser & Wyeth, "GameFlow: A Model for Evaluating Player Enjoyment in Games", 2005).
- 신뢰도 A.
