Virtual Reality (VR) and Augmented Reality (AR) : A Thriving Technology

The term Virtual reality (VR) & Augmented reality (AR) came into existence in the year 1968 by Ivan Sutherland. But, In today’s era it is a technology which has a huge potential to scale in the market. Virtual reality (VR) and Augmented reality (AR) are taking off in almost or soon to be a part of our lives. It could be from creating a 3D video graphic game, e-commerce, marketing or from walking through a dream house to experiencing a walk in beautiful places. Both of these technologies are known for their enriched experience that brings together a virtual world and the real one with enhanced 3D visuals. This technology allows a user to interact with a computer simulated environment, it is the bridge to experience, feeling and touch the past, present and the future virtual world. Today, VR has grown into a new phase and becomes a distinct field in the world of computing. The usability of VR has already been researched in automobile design, robotics, pharmacy, biology, education, as well as in building design. People are quite aware about the term VR/AR but in this paper I will give a detailed introduction on VR, history of VR , its terminology, use cases and its contribution to the thriving technology

An equity-based incentive mechanism for persistent virtual world content service

Virtual world has the potential to become a future global electronic marketplace, integrating many isolated markets in many areas. To achieve this goal, future virtual world is required to be persistent, implying that a virtual world together with its accumulated content shall exist forever regardless of dynamic changes of its users and owners. Unfortunately, existing virtual worlds, owning by some entities, are not immune from death due to business entity failure. To provide a persistent virtual world, a decentralized architecture is explored, which is constructed on user contributed devices. However, there are many challenges to realize a decentralized virtual world. One important issue is user cooperation in reliable content storage. The devices contributed by users may not be reliable for maintaining all user contents, but users do not have the incentive to provide reliable devices for others. This paper addresses the issue by two steps. First, an indicator, called replica group reliability, is provided to users, which is based on the proposed replicability index. Based on the indicator, users can learn the reliability of their content storage. Then, a new user incentive mechanism, called equity-based node allocation strategy, is proposed to promote user cooperation to collectively maintain reliable content storage. A decentralized algorithm implementing the strategy is designed and the evaluation results show its effectiveness and efficiency.

A Study on Design Requirement Development and Satisfaction for Future Virtual World Systems

Virtual worlds have become global platforms connecting millions of people and containing various technologies. For example, No Man’s Sky (nomanssky.com), a cross-platform virtual world, can dynamically and automatically generate content with the progress of user adventure. AltspaceVR (altvr.com) is a social virtual reality platform supporting motion capture through Microsoft’s Kinect, eye tracking, and mixed reality extension. The changes in industrial investment, market revenue, user population, and consumption drive the evolution of virtual-world-related technologies (e.g., computing infrastructure and interaction devices), which turns into new design requirements and thus results in the requirement satisfaction problem in virtual world system architecture design. In this paper, we first study the new or evolving features of virtual worlds and emerging requirements of system development through market/industry trend analysis, including infrastructure mobility, content diversity, function interconnectivity, immersive environment, and intelligent agents. Based on the trend analysis, we propose a new design requirement space. We, then, discuss the requirement satisfaction of existing system architectures and highlight their limitations through a literature review. The feature-based requirement satisfaction comparison of existing system architectures sheds some light on the future virtual world system development to match the changing trends of the user market. At the end of this study, a new architecture from an ongoing research, called Virtual Net, is discussed, which can provide higher resource sufficiency, computing reliability, content persistency, and service credibility.

Using virtual worlds as a platform for collaborative meetings in healthcare: a feasibility study

BackgroundHealthcare teams often consist of geographically dispersed members. Virtual worlds can support immersive, high-quality, multimedia interaction between remote individuals; this study investigated use of virtual worlds to support remote healthcare quality improvement team meetings.MethodsTwenty individuals (12 female, aged 25–67 [M = 42.3, SD = 11.8]) from 6 healthcare quality improvement teams conducted collaborative tasks in virtual world or face-to-face settings. Quality of collaborative task performances were measured and questionnaires and interviews were used to record participants’ experiences of conducting the tasks and using the virtual world software.ResultsQuality of collaborative task outcomes was high in both face-to-face and virtual world settings. Participant interviews elicited advantages for using virtual worlds in healthcare settings, including the ability of the virtual environment to support tools that cannot be represented in equivalent face-to-face meetings, and the potential for virtual world settings to cause improvements in group-dynamics. Reported disadvantages for future virtual world use in healthcare included the difficulty that people with weaker computer skills may experience with using the software. Participants tended to feel absorbed in the collaborative task they conducted within the virtual world, but did not experience the virtual environment as being ‘real’.ConclusionsVirtual worlds can provide an effective platform for collaborative meetings in healthcare quality improvement, but provision of support to those with weaker computer skills should be ensured, as should the technical reliability of the virtual world being used. Future research could investigate use of virtual worlds in other healthcare settings.

The Griefer and the Stalker: Disruptive Actors in a Second Life Educational Community

Linden Lab’s Second Life (SL) is well-known for its hands-off approach to user conflict-resolution. Although users are given tools to mute and block individual accounts as well as ban undesirable avatars from user-owned land, that does not prevent determined, malicious users from disrupting communities and harassing individuals. This case study focuses on two such malicious users exemplary of two specific types of malevolent virtual world actors: in-world griefers and online stalkers. As part of a decade-long ethnographic research project within the Cypris Chat English language learning community in SL, this paper utilizes data gleaned from notes on participant observation, semi-structured interviews, and first-hand encounters. It categorizes the disparate strategies these individuals have used over the years in their attempts to disrupt group cohesion, sow distrust between students and teachers, humiliate individuals, and foment an atmosphere of fear and anxiety. It then reviews the methods community members used to defend themselves from such attacks and analyzes the efficacy of these strategies. This study builds on our understanding of harassment in virtual worlds and acts as a cautionary tale for future virtual world educators and community leaders considering the development of their own online classes and groups.

Cost optimization in persistent virtual world design

Virtual world has the potential to become a future global electronic market, integrating many isolated markets in many areas. To achieve this goal, future virtual world is required to be persistent, which means that a virtual world together with its accumulated content shall exist forever regardless of the dynamic changes of its virtual world users and virtual world owners. This paper addresses the content-level persistence issue by proposing a persistence framework which consists of three elements: existence, availability, and sufficiency. Following the framework, a decentralized redundancy model is then proposed, which is immune from the possible collapse of virtual world. The key problem in the model is the selection of a redundancy level, which is based on cost optimization. Furthermore, the replica failure timeout mechanism is introduced to improve the model. The simulation results show that the redundancy model helps improve content availability and minimizes cost.

Virtual worlds to support patient group communication? A questionnaire study investigating potential for virtual world focus group use by respiratory patients.

Recent advances in communication technologies enable potential provision of remote education for patients using computer-generated environments known as virtual worlds. Previous research has revealed highly variable levels of patient receptiveness to using information technologies for healthcare-related purposes. This preliminary study involved implementing a questionnaire investigating attitudes and access to computer technologies of respiratory outpatients, in order to assess potential for use of virtual worlds to facilitate health-related education for this sample. Ninety-four patients with a chronic respiratory condition completed surveys, which were distributed at a Chest Clinic. In accordance with our prediction, younger participants were more likely to be able to use, and have access to a computer and some patients were keen to explore use virtual worlds for healthcare-related purposes: Of those with access to computer facilities, 14.50% expressed a willingness to attend a virtual world focus group. Results indicate future virtual world health education facilities should be designed to cater for younger patients, because this group are most likely to accept and use such facilities. Within the study sample, this is likely to comprise of people diagnosed with asthma. Future work could investigate the potential of creating a virtual world asthma education facility.

A Cross Case Analysis of Two Out-of-School Programs Based on Virtual Worlds

There is renewed interest in out-of-school programs for informal learning as a way to complement or supplement formal classrooms. Compelling evidence of learning in the context of virtual worlds is emerging, but few empirically detailed comparisons of programs based on such technologies exist. This article presents a cross-case analysis conducted on two out-of-school programs based on virtual environments involving Global Kid’s “I Dig Science” situated in the virtual platform Teen Second Life and Games, Learning & Society Program’s “Casual Learning Lab” based on the massively multiplayer online game World of Warcraft. Ethnographic methods were used for data collection across both in-game and face-to-face contexts at both sites with virtual and face-to-face data collection techniques used in combination. Analysis involved a code set of eleven a priori themes based on the shared goals of each program, resulting in 44 codes total. In this paper, the authors detail contrasts between the two programs in terms of argumentation, problem-solving, information literacy, and workplace skills, highlighting differences between the two programs in terms of their contrasting “locus of intentionality” (designer versus participant) and concluding with a set of “petite generalizations” in the form of design heuristics for future virtual worlds based programs.

Peer-to-Peer 3D Streaming

Virtual worlds have become very popular in recent years, with trends toward larger worlds and more user-generated content. The growth of 3D content in virtual worlds will make real-time content streaming (or 3D streaming) increasingly attractive for developers. To meet the demands of a large user base while lowering costs, peer-to-peer (P2P) content delivery holds the promise for a paradigm shift in how future virtual worlds will be deployed and used. The authors define both the problem and solution spaces for P2P 3D streaming - by outlining its requirements and challenges - and categorize existing proposals.

Learning in the Virtual World: the Pedagogical Potentials of Massively Multiplayer Online Role Playing Games

A much more attractive way to use the internet was discovered. Users are represented by avatars in the fantasy persistent 3D world, and the avatars apparently come to occupy a special place in the hearts of their creators (Castronova, 2001). At present, millions of people worldwide have accounts to some kind of virtual environments. Virtual world may soon become the primary venue for all online activities (Castronova, 2001) including learning. Imagine that one can gain knowledge and skills by social interactions in virtual worlds. A massively multi-student online learning environment (MMOLE) is a pedagogically designed space where students would spend much time learning online by doing and interacting with others. Furthermore, massively multiplayer online games (MMOGs) or massively multiplayer online role playing games (MMORPGs) allow individuals, through their avatars, to learn in the service of games goals and through problem solving and collaboration. This article aims at exploring the pedagogical potentials of virtual worlds. The strengths and weaknesses will be outlined and some of the issues will be discussed through case studies. Hopefully, lessons can be learned and the future virtual worlds can become a more powerful and effective environment to engage students in learning.
