The Problem

With people experiencing disabling hearing loss projected to reach 711 million by 2050, existing sign language learning tools remain flat, non-immersive, and limited to a single country's sign language per app.

BridgesXR addresses this by combining immersive VR learning with cross-cultural sign language support — covering Malaysian Sign Language (BIM), American Sign Language (ASL), and British Sign Language (BSL) — with cultural localisation connecting sign vocabulary to local context.

What I Built in 72 Hours

Unity Development

  • Scene setup, interaction logic, gesture tracking system, UI flow, and game loop
  • Custom gesture recording and matching system — recorded hand joint node data, matched against stored patterns. No external AI APIs. No cost.
  • Hand tracking via XR Interaction Toolkit — controller-free, hands-only interaction
  • 1-to-1 virtual classroom with gesture-based communication and auto-translation

Team & Product

  • Led a 4-person team through 72 hours of continuous development
  • Project direction, task delegation, and all pitching and presentation to judges
  • Gamified learning structure with tiered progression (Tier 1, Tier 2)
  • Multi-language support: BIM, ASL, BSL in one app with cultural localisation
