RE@CT - Immersive Production and Delivery of Interactive 3D Content

International audienceThis paper describes the aims and concepts of the FP7 RE@CT project. Building upon the latest advances in 3D capture and free-viewpoint video RE@CT aims to revolutionise the production of realistic characters and significantly reduce costs by developing an automated process to extract and represent animated characters from actor performance capture in a multiple camera studio. The key innovation is the development of methods for analysis and representation of 3D video to allow reuse for real-time interactive animation. This will enable efficient authoring of interactive characters with video quality appearance and motion

Setting the stage for the future progress of virtual reality production for designers

One of the most important questions for any designer or artist using Virtual Reality (VR) is not to use it as a gimmick. VR needs be used to communicate knowledge and ideas, add new views and take you where only VR can take you. How we experience VR, augmented reality or 360-degree video is important. It is quite likely that augmented reality will be the most popular of these forms in the future. But for learning and education, understanding designers working practices the VR headset maybe more effective as it occupies users’ full vision with less distraction. Its solitary nature could be one of its strengths when used appropriately. This paper seeks to show how VR could be a useful tool to help students under- stand the design process through its representation of design studios, design artefacts, and the making process. The paper also discusses the opportunity to develop a broader visual language for VR and to offer an alternative approach beyond the “gaming aesthetic” that often characterises the medium. A key aim being to create a visually authentic user experience. Jonathan Hamilton has been a practicing designer and lecturer for 30 years, with 14 years as a full-time lecturer and researcher, at one of the UK’s largest art and design universities; Nottingham Trent University (NTU). In discussions with col- leagues over these years they have noticed changes in student understanding of the design process and professional practice. Studio visits are an essential part of this student understanding, yet restricted, as many design studios can only take a small number of students at a time. With UK graphic design cohorts well over 100 students this means only a small percentage can visit any one studio. Exposure to a variety of studios, and their different working methods, helps students to understand that there are a range of approaches to the design process, which they could then be applied to their own work. This paper reports on a research project “Communities of Design” lead by Hamilton and theatre design expert Kate Burnett, in its first case study investigating approaches to documenting the design studio of a recently deceased, international opera theatre designer; Paul Brown, using an alternative method of capturing the space for VR. This method intends to produce an authentic representation of the space capturing atmosphere, mood, light qualities and detailed surface textures, to try and give a more representative experience of being in the studio. As well as documenting the space with VR, video interviews were made with Browns’ studio assistants and collaborators, filmed in the studio space before it was dismantled after his death. Browns’ design models, artefacts and drawings with their complex surface treatments were also documented using a range of methods and technologies including video, photography and 3D scanning. The intention being to include these within the VR space but also to have this content accessible online for when VR is not available for students

Sonic interactions in virtual environments

This book tackles the design of 3D spatial interactions in an audio-centered and audio-first perspective, providing the fundamental notions related to the creation and evaluation of immersive sonic experiences. The key elements that enhance the sensation of place in a virtual environment (VE) are: Immersive audio: the computational aspects of the acoustical-space properties of Virutal Reality (VR) technologies Sonic interaction: the human-computer interplay through auditory feedback in VE VR systems: naturally support multimodal integration, impacting different application domains Sonic Interactions in Virtual Environments will feature state-of-the-art research on real-time auralization, sonic interaction design in VR, quality of the experience in multimodal scenarios, and applications. Contributors and editors include interdisciplinary experts from the fields of computer science, engineering, acoustics, psychology, design, humanities, and beyond. Their mission is to shape an emerging new field of study at the intersection of sonic interaction design and immersive media, embracing an archipelago of existing research spread in different audio communities and to increase among the VR communities, researchers, and practitioners, the awareness of the importance of sonic elements when designing immersive environments

Design methodology for 360-degree immersive video applications

360-degree immersive video applications for Head Mounted Display (HMD) devices offer great potential in providing engaging forms of experiential media solutions. Design challenges emerge though by this new kind of immersive media due to the 2D form of resources used for their construction, the lack of depth, the limited interaction, and the need to address the sense of presence. In addition, the use of Virtual Reality (VR) is related to cybersickness effects imposing further implications in moderate motion design tasks. This research project provides a systematic methodological approach in addressing those challenges and implications in 360-degree immersive video applications design. By studying and analysing methods and techniques efficiently used in the area of VR and Games design, a rigorous methodological design process is proposed. This process is introduced by the specification of the iVID (Immersive Video Interaction Design) framework. The efficiency of the iVID framework and the design methods and techniques it proposes is evaluated through two phases of user studies. Two different 360-degree immersive video prototypes have been created to serve the studies purposes. The analysis of the purposes of the studies ed to the definition of a set of design guidelines to be followed along with the iVID framework for designing 360-degree video-based experiences that are engaging and immersive

This article explores the applicability and potential of Social VR in the broadcast sector, focusing on a live TV show use case. For such a purpose, a novel and lightweight Social VR platform is introduced. The platform provides three key outstanding features compared to state-of-the-art solutions. First, it allows a real-time integration of remote users in shared virtual environments, using realistic volumetric representations and affordable capturing systems, thus not relying on the use of synthetic avatars. Second, it supports a seamless and rich integration of heterogeneous media formats, including 3D scenarios, dynamic volumetric representation of users and (live/stored) stereoscopic 2D and 180º/360º videos. Third, it enables low-latency interaction between the volumetric users and a video-based presenter (Chroma keying), and a dynamic control of the media playout to adapt to the session’s evolution. The production process of an immersive TV show to be able to evaluate the experience is also described. On the one hand, the results from objective tests show the satisfactory performance of the platform. On the other hand, the promising results from user tests support the potential impact of the presented platform, opening up new opportunities in the broadcast sector, among others.This work has been partially funded by the European Union’s Horizon 2020 program, under agreement nº 762111 (VRTogether project), and partially by ACCIÓ, under agreement COMRDI18-1-0008 (ViVIM project).
