International Workshop on Cross-Reality (XR) Interaction @ ACM ISS 2020

We are organising the first international workshop on Cross-Reality (XR) Interaction. XR describes the transition between or concurrent usage of multiple systems on the reality-virtuality continuum. While some expect the distinctions between Augmented Reality (AR) and Virtual Reality (VR) to fade away in time, it is still helpful to see them positioned in a Milgram’s Reality-Virtuality continuum of 'realities' with various degrees of virtual content. Being a continuum, it is possible to envision (i) a smooth transition between systems using different degrees of virtuality or (ii) collaboration between users using different systems with different degrees of virtuality. This workshop aims to bring together researchers and practitioners that are interested in XR to identify current issues and future directions of research while the long-term goal is to create a strong interdisciplinary research community and foster future development of the discipline and collaborations.

Call for Participation

You are invited to participate in the first international workshop on Cross-Reality (XR) Interaction that describes the usage and transition between different systems on the reality-virtuality continuum (e.g. from reality to augmented reality (AR) and virtual reality (VR)) or concurrent usage of multiple systems on this continuum for collaborative purposes. The aim of the workshop is to bring together a community of researchers, designers and practitioners who are interested in `cross-reality' (XR) interaction from an academic or practical perspective. We invite you to make submissions relating to the workshop topic or any of the themes of the workshop:

  • XR conceptual models and design principles
  • Interaction, transition, and visualization or perception techniques
  • Real-world tool use and tangibles as input to XR systems
  • Collaboration across the reality-virtuality continuum
  • Input and output devices
  • Use cases in, e.g., education, industry, transportation, sports, healthcare
  • Evaluation of XR experiences
  • Privacy and security in XR
  • Any other XR related topic

Prospective participants should submit a 2 to 4 page position or work-in-progress paper in the ACM Master Article Submission Template (single-column, references do not count towards page limit) describing their interest and/orprevious, current, or future work related to the workshop topic. Submissions are managed in the EasyChair submission system.

The deadline for submissions is 7 October 2020. These will be juried by an expert committee who will select participants based on the relevance and quality of the work on the broad domain of XR interaction. Each participantwill have five minutes to present their position/work at the workshop, and at least one author of each accepted paper must attend the workshop and be registered for at least one day of the conference.

The proceedings of the workshop will be published on the website and on an online repository that is indexed by Google scholar (e.g. HAL, aRxive).

The workshop will be organised online due to the pandemic. We will do our best to accommodate participants in disparate time-zones.

Submissions and questions should be emailed to

Submission and dates


Our half-day workshop will take place exclusively online via Mozilla Hubs, an increasingly popular 3D collaboration platform that is accessible to both VR and standard browser-based users. Group activities will be supported via Miro, a collaborative online whiteboard platform designed for remote teams.

Keynote: Dr Anasol Peña-Rios

Anasol Peña-Rios is a Senior Researcher at BT Research Labs in Adastral Park, Ipswich, where she specialises on AI and Immersive Technologies (VR/AR/MR). In addition, she is a Visiting Fellow at the University of Essex (UK), from where she holds a PhD in Computer Science and an MSc in Advanced Web Engineering. Previously, she completed a BEng in Information Technology at the Instituto Politécnico Nacional (Mexico).

Anasol has been personally driving the agenda on exploring the use of AI, digital twins and immersive technologies in the context of BT´s field force operations. Her work contributed to BT´s portfolio who was presented with a Global Telecoms Business Innovation Award (2017), and an IEEE Outstanding Organisation Award (2017). In addition, her project was highly commended at the IET Innovation Awards 2018. She was awarded Best KTP Associate 2016 by the University of Essex Research and Enterprise office and was shortlisted for the Computing Women in IT Excellence Awards 2018.

Anasol is an IEEE Senior Member, Board Member and co-founder of the Immersive Learning Research Network, and Board Member of the Creative Science Foundation. She serves as Associate Editor of EAI Endorsed Transactions on e-Learning and as a Review Editor of Frontiers’ Human-Media Interaction theme. Her other professional contributions include numerous peer-reviewed publications and editorial work, in addition, to serve as chair and co-organiser of numerous academic conferences. She has more than 15 years’ professional experience in industry, working in close collaboration with international multidisciplinary teams.


Post-workshop plans

We plan to leave this web site up and running and have the papers available for interested stakeholders. The web site will also serve as the entrance point for the future activities presented below.

We are planning to submit a report article about the workshop to the relevant journal (e.g. IEEE Access, Interact). Depending on the state of research presented in the accepted papers we will plan to hold an open call in a special issue of a relevant journal as well.

With one of the workshop aims being to establish future directions of the XR interaction, we will also hold a discussion for possible ways of strengthening the XR community and further promote the field through various project proposals such as the European Research Council calls Marie Skłodowska-Curie Innovative Training Networks and Cost action. The workshop will thus also serve as a platform for future collaborations between participants.
