Creating and Updating Digital Twins for Enabling XR Applications

Special Session at AIxVR 2025 (January 27-29, 2025, Lisbon, Portugal)

Call for Papers

Digital twins of city spaces, landmarks or industrial environments are important enablers of VR and AR applications in domains such as city planning and maintenance, tourism, media, manufacturing and logistics. Creating high fidelity representations of the real world, and in particular keeping them up-to-date, is still a costly process. Leveraging data that can be captured at low cost, e.g. from vehicles driving through the space to be captured, from robots navigating in the environment, or from consumer media, could significantly reduce the costs and allow for the detection of changes and more frequent updates of digital twins. AI-based methods for 3D reconstruction and scene understanding are enablers for this process.

Topics of interest for this Special Session include, but are not limited to:

  • 3D reconstruction from “in the wild data”
  • Improvement of 2D/3D data representation (e.g., superresolution) in order to update the quality of the resulting digital twin
  • Multimedia analysis for understanding scene semantics and dynamicity
  • Multimodal datasets for digital twin creation and scene understanding
  • Generative AI and foundation models for digital twin creation and/or synthetic data generation
  • Combining synthetic and real data for improving scene understanding
  • Optimized multimedia content analysis for real-time and low-latency XR applications
  • Human interfacing and interaction optimization
  • Privacy and security aspects and mitigations for captured content used for digital twin creation/update


The submission to this session can be:

  • Long papers describing novel methods or their adaptation to specific applications or
  • Short papers describing emerging work or open challenges.


This workshop / special session is part of IEEE AIxVR, which is sponsored by IEEE’s Technical Committee of Semantic Computing and as such committed to the ethical, moral, and legal guidelines specified in the equity, diversity, and inclusion statements of IEEE.

SUBMISSION INSTRUCTIONS: Authors should submit their manuscripts in double-column IEEE format following the official IEEE Manuscript Formatting guidelines. All papers should be double-blind. Submissions will undergo a thorough peer review by at least three (long papers) or two (short papers) international program committee members regarding their scientific value and contribution. For accepted contributions, one author must register at the full conference rate and present the work at the conference. Also, consider the IEEE policies for publications (i.e., you must own copyright to all parts, and the manuscript must be original and not currently under review elsewhere).

Special session papers will be included in the conference proceedings, which will be published by IEEE Computer Society Press and submitted for inclusion in the IEEE Xplore Digital Library.


Submission is done via the main conference submission system (link to be announced).


Authors are expected to present their papers on-site at AIxVR.
