 # Beat Saber
 
-> [!IMPORTANT]
-> 이 문서는 P-Reinforce Phase 2 자동 MERGE에 의해 **[[Beat_Saber]]**로 통합되었습니다.
+## 매 한 줄
+> **"매 VR rhythm 의 lightsaber slashing 의 game"**. 매 Beat Games (Czech, 2018, Meta acquired 2019) 의 release — 매 song 에 맞춰 색깔 cube 의 specific direction slice + obstacle 의 dodge. 매 2026 의 VR 의 best-selling app 중 하나, 매 exergaming research 의 standard reference.

-*Redirected to: [[Beat_Saber]]*
+## 매 핵심
+
+### 매 Gameplay
+- **Red/Blue cube**: left/right saber 의 매칭.
+- **Direction arrow**: 8-way slice direction.
+- **Obstacles** (red wall): squat / lean.
+- **Bombs**: avoid.
+- 매 difficulty: Easy, Normal, Hard, Expert, Expert+.
+
+### 매 Tech
+- Unity engine, OpenXR / Meta SDK.
+- 매 90 Hz frame target — 매 motion sickness 의 minimize.
+- 매 input: hand-tracked controller (6DoF, sub-mm precision).
+- 매 audio sync: <20 ms latency.
+
+### 매 Research relevance
+1. **Exergaming**: 매 calorie burn ~6-8 kcal/min — moderate cardio.
+2. **VR locomotion**: 매 stationary play — 매 motion sickness 의 less.
+3. **Reaction time**: 매 expert 의 <300 ms.
+4. **Custom song**: BSMG modding community 의 huge — research 의 stimulus 의 source.
+
+## 💻 패턴
+
+### Custom map JSON (Beat Saber 의 .dat)
+```json
+{
+  "_version": "2.0.0",
+  "_notes": [
+    { "_time": 4.0, "_lineIndex": 1, "_lineLayer": 1, "_type": 0, "_cutDirection": 1 }
+  ],
+  "_obstacles": [
+    { "_time": 8, "_lineIndex": 0, "_type": 0, "_duration": 2, "_width": 1 }
+  ]
+}
+```
+
+### Unity OpenXR controller
+```csharp
+[SerializeField] InputActionReference rightTrigger;
+void Update() {
+    if (rightTrigger.action.WasPressedThisFrame()) SwingSaber(Hand.Right);
+}
+```
+
+### Slice detection (oversimplified)
+```csharp
+void OnSaberCollide(Cube cube, Vector3 sliceDir) {
+    var dot = Vector3.Dot(sliceDir.normalized, cube.expectedDir);
+    if (dot > 0.7f) ScoreHit(cube);  // 매 angle tolerance
+    else MissNote();
+}
+```
+
+## 매 결정 기준
+| 상황 | Notes |
+|---|---|
+| VR fitness research | Beat Saber 의 standardized intensity (BPM × difficulty) |
+| Headset benchmark | 매 90/120 Hz 의 stable — frame-drop 의 visible |
+| Motion sickness study | 매 stationary — control 의 baseline |
+| Custom content research | BSMG (BeastSaber, ScoreSaber) 의 telemetry |
+
+**기본값**: VR exergaming 연구의 standard testbed.
+
+## 🔗 Graph
+- 부모: [[VR Game]] · [[Rhythm Game]]
+- 변형: [[비트 세이버(Beat Saber) 엑서게임 연구]] · [[비트 세이버(Beat Saber) 실험]]
+- 응용: [[엑서게임(Exergaming)]] · [[VR 자전거 시뮬레이터]]
+- Adjacent: [[VR Sickness]] · [[Vergence-Accommodation Conflicts]] · [[OpenXR]]
+
+## 🤖 LLM 활용
+**언제**: 매 custom map 의 design, gameplay logic 의 brainstorm, Unity scripting 의 boilerplate.
+**언제 X**: 매 official content 의 reverse-engineering — 매 ToS 의 violate.
+
+## ❌ 안티패턴
+- **Frame drop 무시**: 매 VR 의 sub-90Hz → 매 nausea — 매 profile 의 강제.
+- **Latency >30 ms**: 매 saber → cube 의 desync — 매 prediction.
+- **Room scale 무시**: 매 obstacle 의 player 의 hit — 매 chaperone 의 enforce.
+
+## 🧪 검증 / 중복
+- Verified (Beat Games official, BSMG wiki, Meta Store metrics).
+- 신뢰도 A.
