Use Case 1:

Federated Metaverse

Real-time holographic communications in eXtended Reality (XR) environments bring the promise to become a dominant social interaction, collaboration and communication medium in the years to come, and an essential enabler towards the Metaverse. Currently, most state-of-the-art multiuser Social XR platforms rely on the use of synthetic avatars. In this context, recent studies have reflected on remarkable benefits of providing realistic users’ representations in such services, in terms of trustworthiness, as well as of levels of embodiment, co-presence, and quality of interaction.


SUNRISE-6G will count with a worldwide pioneering platform, called HoloMIT, able to provide real-time multiuser holographic communications with realistic and volumetric user (self and others’) representations, using low-cost and off-the-shelf XR capture and rendering hardware. Up to date, HoloMIT has been assessed and validated in different scenarios, for a set of relevant use cases, such as collaborative viewing, interactive virtual and events and virtual meetings, obtaining satisfactory and promising results.


However, state-of-the-art holographic communication (and Metaverse-like) technologies and platforms still encounter key needs and challenges in terms of mainly:

Performance (e.g., delays, fps, resolution, stability…)

Resources consumption (processing, bandwidth…)

Adaptability and scalability (and thus inter-operability)

Effective deployment over multi-domain and heterogeneous scenarios. SUNRISE-6G will provide key technological (network, cloud continuum, cognitive orchestration) enablers, and key Camara Service APIs via the Open Federation Framework as well as federated facilities, to effectively overcoming such challenges

To effectively enable scalable multiuser XR holographic communication services with realistic and volumetric user representations captured in real-time, between users connected through remote (cross-country) 6G experimentation facilities (6G-XR, 6G-Bricks), thanks to a smart and dynamic adaptation based on the available computing and network resources, and orchestration policies.
