VR Gesture Drum Trainer

Learn drumming through spatial muscle memory in VR before graduating to your real drum kit.

What is this?

VR Gesture Drum Trainer is a rhythm training application for Meta Quest 3 that teaches fundamental drumming patterns through hand-tracked gesture following. Players pursue animated gesture trails in 3D space, building coordination and muscle memory in a low-stakes, gamified environment. It bridges the gap between "no drumming experience" and "ready to play Phantom Rack," capitalizing on Quest 3's improved hand tracking and the growing market demand for skill-building rhythm games.

Features

• Hand-tracked gesture following – Follow floating 3D trails using precise hand tracking
• Progressive lesson system – Structured curriculum from basic patterns to complex combinations
• Real-time accuracy feedback – Instant scoring on timing, spatial precision, and consistency
• Spatial muscle memory – Build coordination through repetition in 3D space
• Ready-to-graduate path – Transition smoothly to Phantom Rack or other VR drum instruments
• Quest 3 optimized – Leverages latest hand tracking hardware for responsive gameplay

Quick Start

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/vr-gesture-drum-trainer.git
   cd vr-gesture-drum-trainer
   

2. Open in Unity (2022 LTS or later) with Meta XR SDK installed

3. Install dependencies:

   pip install -r requirements.txt
   

4. Build and deploy to Quest 3:

   unity -quit -batchmode -buildTarget Android -executeMethod BuildScript.Build
   

Usage

Starting a Lesson

1. Launch the app on your Quest 3
2. Select a lesson from the main menu (Assets/Scenes/MainMenu.unity)
3. Follow the animated gesture trails with your hands
4. Receive real-time accuracy scores and feedback

Lesson Structure

Lessons are defined in JSON (e.g., Assets/Resources/Lessons/lesson_01.json):

{
  "id": "lesson_01",
  "name": "Basic Grip",
  "difficulty": 1,
  "patterns": [
    {
      "gesture": "vertical_tap",
      "hand": "both",
      "duration": 2.0,
      "target_height": 1.5
    }
  ]
}

Core API

GesturePattern – Defines a single drumming motion:

GesturePattern pattern = new GesturePattern(
  gestureType: "tap",
  targetPosition: new Vector3(0, 1.5f, 0),
  duration: 1.0f
);

AccuracyTracker – Scores player performance:

float score = accuracyTracker.CalculateAccuracy(
  detectedPosition: handPosition,
  targetPosition: patternTarget,
  timingOffset: deltaTime
);

HandPoseDetector – Recognizes hand positions and gestures via Quest tracking:

HandPose pose = handPoseDetector.DetectPose(Hand.Right);
