Defining Virtual Reality Because virtual reality is a new medium, its definition is still in flux. The researchers and users of VR naturally have their own points of view. Those less familiar with the field may have slightly different ...
Understanding Virtual Reality arrives at a time when the technologies behind virtual reality have advanced to the point that it is possible to develop and deploy meaningful, productive virtual reality applications. The aim of this thorough, accessible exploration is to help you take advantage of this moment, equipping you with the understanding needed to identify and prepare for ways VR can be used in your field, whatever your field may be. By approaching VR as a communications medium, the authors have created a resource that will remain relevant even as the underlying technologies evolve. You get a history of VR, along with a good look at systems currently in use. However, the focus remains squarely on the application of VR and the many issues that arise in the application design and implementation, including hardware requirements, system integration, interaction techniques, and usability. This book also counters both exaggerated claims for VR and the view that would reduce it to entertainment, citing dozens of real-world examples from many different fields and presenting (in a series of appendices) four in-depth application case studies. * Substantive, illuminating coverage designed for technical and business readers and well-suited to the classroom. * Examines VR's constituent technologies, drawn from visualization, representation, graphics, human-computer interaction, and other fields, and explains how they are being united in cohesive VR systems. * Via a companion Web site, provides additional case studies, tutorials, instructional materials, and a link to an open-source VR programming system.

Virtual. Reality. This chapter has two broad aims: firstly, it explores various historical strands surrounding the development of virtual reality, and secondly it critically analyses debates surrounding the virtual and the real.
The idea of virtual realities has a long and complex historical trajectory, spanning from Plato's concept of the cave and the simulacrum, to artistic styles such as Trompe L'oeil, and more recently developments in 3D film, television and gaming. However, this book will pay particular attention to the time between the 1980s to the 1990s when virtual reality and cyberspace were represented, particularly in fiction, as a wondrous technology that enabled transcendence from the limitations of physical embodiment. The purpose of this critical historical analysis of representations of virtual reality is to examine how they might deny, repress or overlook embodied experience. Specifically, the author will contend that embodiment is a fundamental aspect of immersion in virtual reality, rather than something which is to be transcended. In this way, the book aims to challenge distorted ideas about transcendence and productively contribute to debates about embodiment and technology.
Haptics for Virtual Reality and Teleoperation
Release on 2012-12-14 | by Matjaž Mihelj
Virtual reality is composed of an interactive computer simulation, which senses the user's state and operation and replaces or augments sensory feedback information to one or more senses in a way that the user gets a sense of being ...
This book covers all topics relevant for the design of haptic interfaces and teleoperation systems. The book provides the basic knowledge required for understanding more complex approaches and more importantly it introduces all issues that must be considered for designing efficient and safe haptic interfaces. Topics covered in this book provide insight into all relevant components of a haptic system. The reader is guided from understanding the virtual reality concept to the final goal of being able to design haptic interfaces for specific tasks such as nanomanipulation. The introduction chapter positions the haptic interfaces within the virtual reality context. In order to design haptic interfaces that will comply with human capabilities at least basic understanding of human sensors-motor system is required. An overview of this topic is provided in the chapter related to human haptics. The book does not try to introduce the state-of-the-art haptic interface solutions because these tend to change quickly. Only a careful selection of different kinematic configurations is shown to introduce the reader into this field. Mathematical models of virtual environment, collision detection and force rendering topics are strongly interrelated and are described in the next two chapters. The interaction with the virtual environment is simulated with a haptic interface. Impedance and admittance based approaches to haptic robot control are presented. Stability issues of haptic interaction are analyzed in details and solutions are proposed for guaranteeing stable and safe operation. Finally, haptic interaction is extended to teleoperation systems. Virtual fixtures which improve the teleoperation and human-robot cooperation in complex environments are covered next and the last chapter presents nanomanipulation as one specific example of teleoperation.

With the advent of the internet and handheld or wearable media systems that plunge the user into 360o video, augmented—or virtual reality—technology is changing how stories are told and created. In this book, John V. Pavlik argues that a new form of mediated communication has emerged: experiential news. Experiential media delivers not just news stories but also news experiences, in which the consumer engages news as a participant or virtual eyewitness in immersive, multisensory, and interactive narratives. Pavlik describes and analyzes new tools and approaches that allow journalists to tell stories that go beyond text and image. He delves into developing forms such as virtual reality, haptic technologies, interactive documentaries, and drone media, presenting the principles of how to design and frame a story using these techniques. Pavlik warns that although experiential news can heighten user engagement and increase understanding, it may also fuel the transformation of fake news into artificial realities, and he discusses the standards of ethics and accuracy needed to build public trust in journalism in the age of virtual reality. Journalism in the Age of Virtual Reality offers important lessons for practitioners seeking to produce quality experiential news and those interested in the ethical considerations that experiential media raise for journalism and the public.

Virtual reality (VR) provides immersive stereoscopic visualization of virtual environments, and the visualization effect and computer graphics are critical to enhancing the engagement of participants and achieving optimal education and training effectiveness. Constructing realistic 3D models and scenarios for a specific application of VR simulation is no easy task. There are many different tools for 3D modeling. However, many of the modeling tools are used for manufacturing and product design applications and have advanced features and functions which may not be applicable to different levels of users and various specializations. Cases on Virtual Reality Modeling in Healthcare introduces the use of Blender for VR 3D modeling, demonstrates healthcare applications, and examines potential uses in modeling, dressing, and animation in healthcare. Covering a range of topics such as cross reality, rehabilitation games, and augmented reality, this book is ideal for engineers, industry professionals, practitioners, researchers, academicians, instructors, and students.

Abstract This chapter outlines the structure for a virtual reality (VR) ethical tool grounded in John Dewey's concept of dramatic rehearsal. The culmination of ethical thinking on empathy, moral imagination and principlism is brought ...
This book examines the ethics of virtual reality (VR) technologies. New forms of virtual reality are emerging in society, not just from low-cost gaming headsets, or augmented reality apps on phones, but from simulated “deep fake” images and videos on social media. This book subjects the new VR technological landscape to ethical scrutiny: assessing the benefits, risks and regulatory practices that shape it. Though often associated with gaming, education and therapy, VR can also be used for moral enhancement. Journalists, artists, philanthropic and non-governmental organisations are using VR films, games and installations to stimulate user empathy to marginalised peoples through a combination of immersion, embodiment and persuasion. This book critically assesses the use of VR for empathy arousal and pro-social behaviour change, culminating in the development of a VR “ethical tool” – a device to facilitate reflective ethical judgement. Drawing upon the pragmatist philosophy of John Dewey, virtual reality is reshaped as “dramatic rehearsal”. This book explains how a combination of immersive environment-building, moral imagination, choice architecture and reflective engagement can stimulate a future-focused and empathic ethics for users of the technology.

Virtual Reality has the potential to provide descriptive and practical information for medical training and therapy while relieving the patient or the physician. Multimodal interactions between the user and the virtual environment facilitate the generation of high-fidelity sensory impressions, by using not only visual and auditory, but also kinesthetic, tactile, and even olfactory feedback modalities. On the basis of the existing physiological constraints, Virtual Reality in Medicine derives the technical requirements and design principles of multimodal input devices, displays, and rendering techniques. Resulting from a course taught by the authors, Virtual Reality in Medicine presents examples for surgical training, intra-operative augmentation, and rehabilitation that are already in use as well as those currently in development. It is well suited as introductory material for engineering and computer science students, as well as researchers who want to learn more about basic technologies in the area of virtual reality applied to medicine. It also provides a broad overview to non-engineering students as well as clinical users, who desire to learn more about the current state of the art and future applications of this technology.
Investigating Rollenwahrnehmung Perspective and Space through Virtual Reality related Game Interfaces
Release on 2021-01-03 | by Daniel P. O. Wiedemann
“Using Presence Questionnaires in Virtual Reality”. In Proceedings of the 2019 CHI Conference on Human Factors in Computing Systems (CHI '19). ACM, New York, 1-12. DOI 10.1145/3290605.3300590 Scrivener, S.A.R. 2002.
This book is the publication of my PhD dissertation and is written in the corresponding style. The included research provides explorations and investigative reflections on Rollenwahrnehmung (a newly coined phrase meaning role perception/fulfillment), Perspective and Space through Virtual Reality (VR) game interfaces. A number of important topics will be addressed, like the creation of new experiences in the context of VR, the extension and new development of various interaction paradigms, various User Experience (UX) aspects and user guidance in a sophisticated new medium. Placed in the field of design practice, this research focuses on the creation of digital gaming artifacts, while extrapolating insights and guidelines concerning VR interfaces. Hence, this practice-based research is derived from a portfolio of specifically developed interactive artifacts, following the methodological approach of Constructive Design Research. These include the VR related games Nicely Dicely, LizzE - And the Light of Dreams and Gooze. They were used for various Lab experiments and Showroom presentations, while continually being refined throughout an iterative process. Nicely Dicely is an abstract game based on physics. In Local Multiplayer, up to four players are able to compete or collaborate. It is not a VR game per se, but features both, Monoscopic and 3D Stereoscopic Vision modes, which were tested in an experiment on their effect on Player Immersion. LizzE - And the Light of Dreams is a Singleplayer 3rd Person Hack and Slay game based in a fantasy universe. In an experiment, the game was used to primarily investigate in which ways 3rd Person VR games can work for a broad audience, regarding camera behavior. Gooze is a 1st Person VR puzzle game, taking place in a realistic horror environment with supernatural aspects. It was designed with diverse VR interaction technologies in mind and offers users different options to play the game, depending on available hardware and preferences. The Locomotion and Virtual Object Interaction mechanics were tested in an experiment regarding their UX. In summary, this book illustrates various game, interface and VR designs, informing the emerging field of VR game development of the relationship between UX, interfaces and gameplay. Furthermore, guidelines for designing and developing specific aspects of VR games were identified and each single artifact can be used as a design and development precedent for practice and academia.
