Beat Saber

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.

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)

{
  "_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

[SerializeField] InputActionReference rightTrigger;
void Update() {
    if (rightTrigger.action.WasPressedThisFrame()) SwingSaber(Hand.Right);
}

Slice detection (oversimplified)

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.

  • 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.
