3D-LIVE : live interactions through 3D visual environments

This paper explores Future Internet (FI) 3D-Media technologies and Internet of Things (IoT) in real and virtual environments in order to sense and experiment Real-Time interaction within live situations. The combination of FI testbeds and Living Labs (LL) would enable both researchers and users to explore capacities to enter the 3D Tele-Immersive (TI) application market and to establish new requirements for FI technology and infrastructure. It is expected that combining both FI technology pull and TI market pull would promote and accelerate the creation and adoption, by user communities such as sport practitioners, of innovative TI Services within sport events

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).

Trends in virtual reality technologies for the learning patient

NextMed convened the Medicine Meets Virtual Reality 22 (MMVR 22) conference in 2016. Since 1992, the conference has brought together a diverse group of researchers to share creative solutions for the evolving challenge of integrating virtual reality tools into medical education. Virtual reality (VR) and its enabling technologies utilize hardware and software to simulate environments and encounters where users can interact and learn. The MMVR 22 symposium proceedings contain projects that support a variety of learners: medical students, practitioners, soldiers, and patients. This report will contemplate the trends in virtual reality technologies for patients navigating their medical and healthcare learning. The learning patient seeks more than intervention; they seek prevention. From virtual humans and environments to motion sensors and haptic devices, patients are surrounded by increasingly rich and transformative data-driven tools. Applied data enables VR applications to simulate experience, predict health outcomes, and motivate new behavior. The MMVR 22 presents investigations into the usability of wearable devices, the efficacy of avatar inclusion, and the viability of multi-player gaming. With increasing need for individualized and scalable programming, only committed open source efforts will align instructional designers, technology integrators, trainers, and clinicians. Curriculum and InstructionCurriculum and Instructio

Transmission: A telepresence interface for neural and kinetic interaction

Transmission is both a telepresence performance and a research project. As a real-time visualization tool, Transmission creates alternate representations of neural activity through sound and vision, investigating the effect of interaction on human consciousness. As a sonification project, it creates an immersive experience for two users: a soundscape created by the human mind and the influence of kinetic interaction. An electroencephalographic (EEG) headset interprets a user’s neural activity. An Open Sound Control (OSC) script then translates this data into a real-time particle stream and sound environment at one end. A second user in a remote location modifies this stream in real time through body movement. Together they become a telematic musical interface-communicating through visual and sonic representation of their interactions

Virtual Heritage at iGrid 2000

As part of the iGrid Research Demonstration at INET 2000, we created two Virtual Cultural Heritage environments - "Virtual Harlem" and "Shared Miletus". The purpose of these applications was to explore possibilities in using the combination of high-speed international networks and virtual reality (VR) displays for cultural heritage education. Our ultimate goal is to enable the construction of tele-immersive museums and classes. In this paper we present an overview of the infrastructure used for these applications, and some details of their construction.Comment: 9 pages, 4 figures, INET 2001 (Stockholm, Sweden, 5-8 June 2001

Business Case and Technology Analysis for 5G Low Latency Applications

A large number of new consumer and industrial applications are likely to change the classic operator's business models and provide a wide range of new markets to enter. This article analyses the most relevant 5G use cases that require ultra-low latency, from both technical and business perspectives. Low latency services pose challenging requirements to the network, and to fulfill them operators need to invest in costly changes in their network. In this sense, it is not clear whether such investments are going to be amortized with these new business models. In light of this, specific applications and requirements are described and the potential market benefits for operators are analysed. Conclusions show that operators have clear opportunities to add value and position themselves strongly with the increasing number of services to be provided by 5G.Comment: 18 pages, 5 figure
