At the ATLAS Week Outreach Parallel Session on June 18, 2025, Alexander Sharmazanashvili delivered a detailed status report on the technological developments under the ATLAS-GTU TAI Agreement.
The presentation focused on a suite of interactive, browser-based applications aimed at enhancing detector visualization and educational outreach for the ATLAS experiment. The tools include:
- Tracer-VR: A virtual reality platform for immersive exploration of the ATLAS detector at CERN’s Point-1 site. Users can navigate through four predefined 3D scenes using different drone-like flight modes (circular, beam-pipe-aligned, and free flight), controlled via head movements and Ray Caster interaction.
- Tracer-ART: An augmented reality table-top application that places 3D representations of ATLAS detector components on any flat surface. It enables sectional views and component-level exploration with high performance on mid-range mobile GPUs.
- Tracer-ARB: A lightweight augmented reality extension for printed media, allowing interactive 3D overlays on static diagrams. This tool is fully browser-based, requires no installation, and is optimized for use via mobile device cameras. Five modules covering different subsystems of the ATLAS detector are currently implemented.
The team also outlined future developments:
- Tracer-ARD (AR Door): In the R&D phase, this application will allow virtual navigation within the ATLAS detector environment through spatially anchored AR portals.
- Tracer-ARL (AR Landscape): Planned for development in 2026, this will be a full-scale landscape AR visualization of the entire ATLAS detector.
All applications are cross-platform, web-accessible, and hosted in open-source repositories on CERN GitLab, with a recommendation for use on Chromium-based browsers.
