About the research centre or Inria department

The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.


This project is framed within the EquipEx+ CONTINUUM, that aims a enabling a paradigm shift in the way we perceive, interact and collaborate with complex digital data and digital worlds by placing humans at the centre of the data processing flows. The project will provide scientists, engineers and industrial users with a network of high-performance visualization and immersion platforms for observing, manipulating, understanding and sharing digital data, multi-scale simulations and virtual or augmented experiences. All platforms will allow remote collaboration and will be equipped with mobile equipment that can be loaned to users to facilitate access to these technologies.


In this context, this project focuses on how a user with AR capabilities can ask for remote assistance from one or multiple remote users (VR collaborators). To ensure optimal collaboration, first, remote users need a precise understanding of the workspace of the AR user (workspace awareness). The awareness of the workspace enables the remote collaborators to understand and assess the environment in which the AR user is located. Second, users should be able to be aware of the actions of the other users (user awareness) and should be able to communicate with traditional interaction modalities, such as voice, gaze and gestures. User awareness is required to ensure efficient communication and interaction among users, as users should be aware of the actions of others. Finally, workspace and user awareness must be synchronized, as interactions are linked with elements of the physical workspace. However, due to the difficulty to ensure free exploration for remote collaborators, workspace awareness still remains an open problem, and it is typically supported either by virtual replicas/reconstructions or video feeds 1. However, with the appearance of radiance field rendering methods such as Neural Radiance Fields (NeRF) 2 or more efficient point-based solutions 3, real-time and high-fidelity reconstruction of physical workspaces are becoming possible.
