Welcome to RALQ

RALQ (Reality Augmented Learning for Chemistry) is an educational platform that helps you learn chemistry through interactive 3D visualizations and augmented reality. This guide will walk you through your first steps with the platform.
RALQ works best on mobile devices for AR features, but you can access 3D visualizations from any device with a modern web browser.

View Your First 3D Molecule

Let’s explore a 3D molecular structure:
  1. Click on “Estructuras Moleculares” from the main menu
  2. You’ll see a gallery of molecules including:
    • Water (H₂O)
    • Caffeine (C₈H₁₀N₄O₂)
    • Benzyl alcohol (C₈H₁₀O)
    • Phenol (C₆H₅OH)
    • Glycerol (C₃H₈O₃)
    • Propane (C₃H₈)
  3. Each molecule card displays:
    • An interactive 3D model that auto-rotates
    • Chemical formula
    • AR viewing button
  4. Interact with the model:
    • Click and drag to rotate the molecule
    • Pinch to zoom in/out
    • Click the “i” button for detailed information (molecular weight, state, formula)
<model-viewer

Try AR Mode on Mobile

To experience augmented reality:
  1. Open RALQ on a mobile device (smartphone or tablet)
  2. Navigate to any molecule page
  3. Click “Ver en Realidad Aumentada” (View in Augmented Reality)
  4. Grant camera permissions when prompted
  5. Point your camera at a flat surface
  6. The molecule will appear in your real-world environment!
AR features require:
  • A mobile device with ARCore (Android) or ARKit (iOS)
  • Camera permissions
  • Good lighting conditions
  • A flat surface for placing the model

​
Available AR Molecules

​
Tips for Success

  • Use mobile for AR: While 3D models work on desktop, AR features require a mobile device
  • Rotate and zoom: Don’t just watch - interact with the 3D models to understand spatial relationships
  • Read the info cards: Click the “i” button on each molecule for molecular weight, state, and formula
  • Practice regularly: The more you explore, the better you’ll understand molecular structures
