FutureEcologies: Towards Mixed Reality Cross-Device Ecologies for The Future of Work

Organizers: Steven Houben (Eindhoven University of Technology, Netherlands),
Nicolai Marquardt (University College London, United Kingdom)

Summary — The Future Ecologies workshop will explore how mixed-reality cross-device ecologies can support the newly emerging modes of hybrid work. The way people are working and collaborating is fundamentally changing as we see a shift towards a distributed, online, and often nomadic work model across spaces, time zones, and roles that have been dramatically accelerated by Covid-19. The goal of this workshop is to bring together academic researchers and practitioners working on the topics of (i) future of work and remote work practices, (ii) cross-device computing, and (iii) collaborative mixed reality, to flesh out a new vision for how immersive technologies can be leveraged to mediate and support these newly emerging modes of work. We aim to document these new modes of ‘future work’ happening now, establish new conceptual approaches and vocabulary to discuss hybrid immersive experiences, and propose new sociotechnical possibilities to address emerging changes in work practices.

Attending — We invite academic researchers, industry experts, and practitioners to submit their interests via our website (registration will open soon). We require the contact details and a short (maximum 1-page) motivation or position statement on the relevance of your research and or expertise for this topic and workshop. The workshop is collocated with ISS'21 so if you would like to attend you need to register for at least one day of the conference and the specific workshop.

Transitional Interfaces in Mixed and Cross-Reality: A new frontier?

Organizers: Hans-Christian Jetter (University of Lübeck, Germany),
Jan-Henrik Schröder (University of Lübeck, Germany),
Jan Gugenheimer (Institut Polytechnique de Paris, Télécom Paris, France),
Mark Billinghurst (University of South Australia, Australia and University of Auckland, New Zealand),
Christoph Anthes (University of Applied Sciences Upper Austria, Hagenberg Campus, Austria),
Mohamed Khamis (University of Glasgow, United Kingdom),
Tiare Feuchtner (University of Konstanz, Germany)

Summary — The rapid proliferation of powerful, yet affordable, off-the-shelf AR/VR head-mounted displays (HMDs) raises questions about how to better integrate such mixed reality technologies into our real-world computing ecosystems and into the real-world physical spaces they inhabit.
We believe that in the future the concept of transitional interfaces (TIs), which was initially introduced by Billinghurst et al.’s "MagicBook" in 2001, will provide a key lens through which mixed reality systems should be analysed, understood, and designed to achieve better integration. Billinghurst et al. already envisioned a system that enables a team of users (e.g. an architect and her clients) to move seamlessly between reality and immersive virtual reality while collaborating on the task at hand in the same physical space.
We believe that similar to how cross-device interaction has blended tabletop computers, digital whiteboards, and mobile devices with our familiar physical and social environment in meeting rooms or even desk lamps, transitional interfaces could help us to seamlessly integrate systems from different locations along the RV-continuum as usable, consistent, and coherent user interfaces in a shared physical space.
Prior work has explored similar concepts: In their ISS 2020 workshop on cross-reality (XR), Simeone et al. envisioned interfaces that enable "(i) a smooth transition between systems using different degrees of virtuality or (ii) collaboration between users using different systems with different degrees of virtuality". Riegler et al. propose cross-virtuality as "a seamless integration and transition between conventional 2D visualization, augmented reality and virtual reality in order to provide users with optimal visual and algorithmic support with maximum cognitive and perceptual suitability, depending on their current tasks and needs".
Our workshop is aimed at bringing together researchers who are working on TIs or related concepts such as XR or XV to create a common ground and mutual understanding for developing this space further. We believe that ACM ISS is an optimal venue for such work, since it brings together the extensive experience of researchers in the field of interactive surfaces and spaces including cross-device interaction and of researchers from the AR/VR/XR/XV community. Focus topics of the workshop include but are not limited to:

  1. Defining TIs: Identify differences and commonalities between transitional interfaces and related terms and terminologies (e.g., cross-reality, cross-virtuality, hybrid user interfaces).
  2. Designing TIs: Compare and discuss designs of interaction and visualization techniques that support seamless transitions while maintaining situational and group awareness.
  3. Evaluating TIs: Develop cognitive models or constructs for "seamlessness", "continuity", or other important qualities of TIs and discuss how to "measure" them in user studies and experiments.
  4. Building TIs: Discuss and compare hard- and software that especially supports or hinders seamless transitions, e.g., video-based vs. optical see-through, different AR/VR engines, platforms for networked virtual environments.

Attending — The full-day workshop will take place as a hybrid event as part of the 2021 ACM Interactive Surfaces and Spaces Conference (ACM ISS 2021) on November 14th in Łódź, Poland. We will ensure that anyone can effectively contribute to the workshop regardless of what the circumstances in November will be. ISS will offer virtual attendance opportunities.
To attend the workshop, we ask prospective participants to submit position papers between 2-4 pages in the ACM Small single column format to jschroeder@imis.uni-luebeck.de. References do not count towards page limit. Position papers will be selected by the workshop organizers based on their relevance to the workshop, the validity of the presented position, and originality of the content. Accepted position papers will be published online on this website.
