Social VR enables people to interact over distance with others in real-time. It allows remote people, typically represented as avatars, to communicate and perform activities together in a shared virtual environment, extending the capabilities of traditional social platforms like Facebook and Netflix. This paper explores the benefits and drawbacks provided by a lightweight and low-cost Social VR platform (SocialVR), in which users are captured by several cameras and reconstructed in real-time. In particular, the paper contributes with (1) the design and evaluation of an experimental protocol for Social VR experiences; (2) the report of a production workflow for this new type of media experiences; and (3) the results of experiments with both end-users (N = 15 pairs) and professionals (N = 22 companies) to evaluate the potential of the SocialVR platform. Results from the questionnaires and semi-structured interviews show that end-users rated positively towards the experiences provided by the SocialVR platform, which enabled them to sense emotions and communicate effortlessly. End-users perceived the photo-realistic experience of SocialVR similar to face-to-face scenarios and appreciated this new creative medium. From a commercial perspective, professionals confirmed the potential of this communication medium and encourage further research for the adoption of the platform in the commercial landscape.@en

The advent of affordable 3D capture and display hardware is making volumetric videoconferencing feasible. This technology increases the immersion of the participants, breaking the flat restriction of 2D screens, by allowing them to collaborate and interact in shared virtual reality spaces. In this paper we introduce the design and development of an architecture intended for volumetric videoconferencing that provides a highly realistic 3D representation of the participants, based on pointclouds. A pointcloud representation is suitable for real-time applications like video conferencing, due to its low-complexity and because it does not need a time consuming reconstruction process. As transport protocol we selected low latency DASH, due to its popularity and client-based adaptation mechanisms for tiling. This paper presents the architectural design, details the implementation, and provides some referential results. The demo will showcase the system in action, enabling volumetric videoconferencing using pointclouds.@en
