Book Synopsis Where are you? Self- and body part localization using virtual reality setups by : Albert van der Veer
Download or read book Where are you? Self- and body part localization using virtual reality setups written by Albert van der Veer and published by Logos Verlag Berlin GmbH. This book was released on 2019-09-19 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a line of original experimental studies on the bodily self, investigating where people locate themselves in their bodies and how accurate they are at localizing their body parts. So far, it was not well known whether people locate themselves in one or more specific regions of their bodies. On the other hand, some systematic distortions in indicating bodily locations were already documented. In the present studies, participants were therefore asked to indicate their self-locations, as well as the locations of several of their body parts, using a self-directed, first-person perspective pointing paradigm in various virtual reality (VR) setups (different head-mounted displays and a large-screen immersive display). Overall, participants were found to locate themselves mainly in the (upper) face and the (upper) torso. However, striking differences in self-localization were found when testing in different VR setups. Upon further investigation, these differences were found to be foremost due to inaccuracies in body part localization. When taking these inaccuracies into account, differences between setups—and also with self-localization outside of VR—largely disappear. Another striking finding was that providing participants—in between pointing phases—with information about their bodies in the form of a real-time animated self-avatar, did not make them more accurate at locating their own body parts. While manipulating their viewpoint to chest-height of their self-avatar did shift the afterwards indicated locations of their own body parts upwards, towards where they were seen on the avatar. Potential explanations for the various new findings, also from tasks outside of VR, are discussed. Taken together, this volume suggests a differential involvement of multi-sensory information processing in experienced self-location within the body and the ability to locate body parts. Self-localization seems to be less flexible, possibly because it is strongly grounded in the 'bodily senses', while body part localization appears more adaptable to the manipulation of sensory stimuli, at least in the visual modality.
Book Synopsis Measuring, modelling and minimizing perceived motion incongruence for vehicle motion simulation by : Diane Cleij
Download or read book Measuring, modelling and minimizing perceived motion incongruence for vehicle motion simulation written by Diane Cleij and published by Logos Verlag Berlin GmbH. This book was released on 2020-01-28 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans always wanted to go faster and higher than their own legs could carry them. This led them to invent numerous types of vehicles to move fast over land, water and air. As training how to handle such vehicles and testing new developments can be dangerous and costly, vehicle motion simulators were invented. Motion-based simulators in particular, combine visual and physical motion cues to provide occupants with a feeling of being in the real vehicle. While visual cues are generally not limited in amplitude, physical cues certainly are, due to the limited simulator motion space. A motion cueing algorithm (MCA) is used to map the vehicle motions onto the simulator motion space. This mapping inherently creates mismatches between the visual and physical motion cues. Due to imperfections in the human perceptual system, not all visual/physical cueing mismatches are perceived. However, if a mismatch is perceived, it can impair the simulation realism and even cause simulator sickness. For MCA design, a good understanding of when mismatches are perceived, and ways to prevent these from occurring, are therefore essential. In this thesis a data-driven approach, using continuous subjective measures of the time-varying Perceived Motion Incongruence (PMI), is adopted. PMI in this case refers to the effect that perceived mismatches between visual and physical motion cues have on the resulting simulator realism. The main goal of this thesis was to develop an MCA-independent off-line prediction method for time-varying PMI during vehicle motion simulation, with the aim of improving motion cueing quality. To this end, a complete roadmap, describing how to measure and model PMI and how to apply such models to predict and minimize PMI in motion simulations is presented. Results from several human-in-the-loop experiments are used to demonstrate the potential of this novel approach.

Available in PDF, EPUB and Kindle. Book excerpt: Despite widespread interest in virtual reality, research and development efforts in synthetic environments (SE)â€"the field encompassing virtual environments, teleoperation, and hybridsâ€"have remained fragmented. Virtual Reality is the first integrated treatment of the topic, presenting current knowledge along with thought-provoking vignettes about a future where SE is commonplace. This volume discusses all aspects of creating a system that will allow human operators to see, hear, smell, taste, move about, give commands, respond to conditions, and manipulate objects effectively in a real or virtual environment. The committee of computer scientists, engineers, and psychologists on the leading edge of SE development explores the potential applications of SE in the areas of manufacturing, medicine, education, training, scientific visualization, and teleoperation in hazardous environments. The committee also offers recommendations for development of improved SE technology, needed studies of human behavior and evaluation of SE systems, and government policy and infrastructure.

Book Synopsis Understanding Virtual Reality by : William R. Sherman
Download or read book Understanding Virtual Reality written by William R. Sherman and published by Morgan Kaufmann. This book was released on 2018-11-08 with total page 938 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding Virtual Reality: Interface, Application, and Design, Second Edition, arrives at a time when the technologies behind virtual reality have advanced dramatically in their development and deployment, providing meaningful and productive virtual reality applications. The aim of this book is to help users take advantage of ways they can identify and prepare for the applications of VR in their field, whatever it may be. The included information counters both exaggerated claims for VR, citing dozens of real-world examples. 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 application design and implementation, including hardware requirements, system integration, interaction techniques and usability. Features substantive, illuminating coverage designed for technical or business readers and the classroom Examines VR's constituent technologies, drawn from visualization, representation, graphics, human-computer interaction and other fields Provides (via a companion website) additional case studies, tutorials, instructional materials and a link to an open-source VR programming system Includes updated perception material and new sections on game engines, optical tracking, VR visual interface software and a new glossary with pictures
Book Synopsis Basic and Clinical Neurocardiology by : J. Andrew Armour
Download or read book Basic and Clinical Neurocardiology written by J. Andrew Armour and published by Oxford University Press. This book was released on 2004-05-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The progression of heart disease is associated with changes in the neurohumoral mechanisms that control cardiac function. The degree to which this neurohumoral remodeling occurs, even before overt signs of cardiac disease become manifest, is important for prognosis. To determine why some patients experience sudden death while others sustain life in the presence of severely compromised cardiac function, the neuronal control of cardiac electrical and mechanical events must be considered. Starting at the level of individual neurons and building upwards, this book describes the synergistic interactions that occur among intrathoracic and CNS feedback loops to permit precise control of regional cardiac behavior. On this basic science foundation, subsequent clinical chapters explore the remodeling that occurs in this system with aging, with the evolution of specific cardiac pathologies, and with the psychological concomitants of heart disease. Most importantly, these chapters provide unique insights into how specific therapies like beta-andrenergic receptor blockade not only affect cardiomyocytes directly but also mitigate the adverse neurohumoral changes that accompany disease processes, such as heart failure and essential hypertension. The paradigm advanced in this volume is that heart disease is a multifaceted phenomenon involving the interplay of neurohumoral, cardiomyocyte and structural elements, each of which depends on the other. With our cumulative understanding of these interdependent processes, new avenues for time-appropriate, targeted methods of treating heart diseases can be developed.

Available in PDF, EPUB and Kindle. Book excerpt: It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

Book Synopsis The Body and the Self by : Jose Luis Bermudez
Download or read book The Body and the Self written by Jose Luis Bermudez and published by MIT Press. This book was released on 1998-01-23 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Body and the Self brings together recent work by philosophers and psychologists on the nature of self-consciousness, the nature of bodily awareness, and the relation between the two. The central problem addressed is How is our grasp of ourselves as one object among others underpinned by the ways in which we use and represent our bodies? The contributors take up such issues as how should we characterize the various distinctive ways we have of being in touch with our own bodies in sensation, proprioception, and action? How exactly does our grip on our bodies as objects connect with our ability to perceive the external environment, and with our ability to engage in various forms of social interaction? Can any of these ways of representing our bodies affect a bridge between body and self?
Book Synopsis Advances in Virtual Reality and Anxiety Disorders by : Brenda K. Wiederhold
Download or read book Advances in Virtual Reality and Anxiety Disorders written by Brenda K. Wiederhold and published by Springer. This book was released on 2014-10-27 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactive computer-generated world of virtual reality has been successful in treating phobias and other anxiety-related conditions, in part because of its distinct advantages over traditional in vivo exposure. Yet many clinicians still think of VR technology as it was in the 1990s–bulky, costly, technically difficult–with little knowledge of its evolution toward more modern, evidence-based, practice-friendly treatment. These updates, and their clinical usefulness, are the subject of Advances in Virtual Reality and Anxiety Disorders, a timely guidebook geared toward integrating up-to-date VR methods into everyday practice. Introductory material covers key virtual reality concepts, provides a brief history of VR as used in therapy for anxiety disorders, addresses the concept of presence, and explains the side effects, known as cybersickness, that affect a small percentage of clients. Chapters in the book's main section detail current techniques and review study findings for using VR in the treatment of: · Claustrophobia. · Panic disorder, agoraphobia, and driving phobia. · Acrophobia and aviophobia. · Arachnophobia. · Social phobia. · Generalized anxiety disorder and OCD. · PTSD. · Plus clinical guidelines for establishing a VR clinic. An in-depth framework for effective (and cost-effective) therapeutic innovations for entrenched problems, Advances in Virtual Reality and Anxiety Disorders will find an engaged audience among psychologists, psychiatrists, social workers, and mental health counselors.eractive
