Luca "Hydr0gen" Vitale

XR Developer · Unity · Immersive & WebAR experiences

I build real-time 3D and immersive experiences for AR / VR / MR headsets, and bring the same interaction design to the web and mobile.

What I work on

  • Real-time 3D & XR — Unity-first, from scene architecture to on-device optimization
  • Standalone headsets — HoloLens 2, Magic Leap, Meta Quest, Apple Vision Pro
  • WebAR — image tracking and 3D on the browser with three.js, A-Frame and MindAR
  • Web & app frontends — React, React Native and Angular
  • Native mobile — Kotlin (Android) and Swift (iOS)
  • Motion capture — full-body and hand tracking with OptiTrack and Vicon
  • Tooling & data — Python pipelines for preprocessing, mesh/JSON handling and validation tools (PyQt / Dash)

Co-designed and developed ARtour, a Unity AR application for cultural tours: QR-anchored localization inside Matterport digital twins, NavMesh-based indoor wayfinding with custom occlusion shader, and an in-app LLM assistant (Gemini 2.0 Flash) with encrypted API key handling and native Android TTS. Evaluated in a 42-participant user study on usability, cognitive load and co-presence.
