Effect of Viewing Conditions on Sickness and Distance Estimation in a Virtual Environment by Jennifer A. Ehrlich Pdf

"Previous research indicates that Helmet Mounted Displays (HMDs) using stereoscopic presentation techniques induce greater Simulator Sickness symptomology than a biocular presentation. However, neither of these presentation methods takes into account the different perspective each eye normally receives as a result of each eye turning to fixate on objects in different depth planes, referred to as vergence movements. The present study examined the effects of a vergence algorithm moderating the stereoscopic display in an HMD in a within subjects comparison to standard stereoscopic and biocular presentations. The experiment used a distance estimation task and the other major variable was incidence of simulator sickness. The experiment task required moving through rooms in a virtual environment and providing distance estimates to different objects. The findings suggest that most participants would recover more easily from simulator sickness symptoms with a vergence viewing condition. However, because this study shows a wide range of individual differences, a vergence adjustment to stereoscopic presentation should not be expected to eliminate the number of participants withdrawing, but only to reduce their number when repeated exposures are involved. Also, the range of individual differences indicates a need for multiple measures of symptomology not only to help identify individuals who are under duress, but to better assess when they have adapted. One candidate measure of duress is dark vergence, based on its objective scaling, its relevance to adaptation, and its correlation with 55 sub-scale scores."--DTIC.

Being Really Virtual by Frank Steinicke Pdf

This book focuses on the recent developments of virtual reality (VR) and immersive technologies, what effect they are having on our modern, digitised society and explores how current developments and advancements in this field are leading to a virtual revolution. Using Ivan Sutherland's ‘The Ultimate Display’ and Moore’s law as a springboard, the author discusses both popular scientific and technological accounts of the past, present and possible futures of VR, looking at current research trends, developments, challenges and ethical considerations to the coming age of differing realities. Being Really Virtual is for researchers, designers and developers of VR and immersive technologies and anyone with an interest in the exponential rise of such technologies and how they are changing the very way we perceive, interact and communicate within our digital society.

Getting Rid of Cybersickness by Andras Kemeny,Jean-Rémy Chardonnet,Florent Colombet Pdf

This book provides a concise overview of VR systems and their cybersickness effects, giving a description of possible reasons and existing solutions to reduce or avoid them. Moreover, the book explores the impact that understanding how efficiently our brains are producing a coherent and rich representation of the perceived outside world would have on helping VR technics to be more efficient and friendly to use. Getting Rid of Cybersickness will help readers to understand the underlying technics and social stakes involved, from engineering design to autonomous vehicle motion sickness to video games, with the hope of providing an insight of VR sickness induced by the emerging immersive technologies. This book will therefore be of interest to academics, researchers and designers within the field of VR, as well as industrial users of VR and driving simulators.

Virtual Environments for Dismounted Soldier Training and Performance by Anonim Pdf

"The U.S. Army has made a considerable investment in the use of virtual environments (VE) to train combat forces, to evaluate new systems and operational concepts, and to rehearse specific missions. While these simulations have predominately focused on training and simulation for mounted soldiers, there is also a need to train infantry and other dismounted soldiers. Although VEs have the potential to immerse dismounted soldiers directly in simulations, there are few successful examples of the use of VE to provide effective training. The effective use of VE for training requires identification of the types of tasks for which VE training is most appropriate, the characteristics of VE systems that are required to provide effective training, and the training strategies that are most appropriate for use with VE. This report presents recommendations for the use of VE for dismounted soldier training and mission rehearsal, and identifies needed future research. They are based on the results of an ARI in-house research program, related programs for which ARI scientists have participated, and the work of other VE researchers. Recommendations include types of tasks for which training in VE is and is not appropriate, interface design recommendations, and ways to reduce side- and after-effects.

Why People Get Lost by Paul A. Dudchenko Pdf

At some point in our lives, most of us have been lost. How does this happen? What are the limits of our ability to find our way? Do we have an innate sense of direction? 'How people get lost' reviews the psychology and neuroscience of navigation. It starts with a history of studies looking at how organisms solve mazes. It then reviews contemporary studies of spatial cognition, and the wayfinding abilities of adults and children. It then considers how specific parts of the brain provide a cognitive map and a neural compass. This book also considers the neurology of spatial disorientation, and the tendency of patients with Alzheimer's disease to lose their way. Within the book, the author considers that, perhaps we get lost simply because our brain's compass becomes misoriented. This book is written for anyone with an interest in navigation and the brain. It assumes no specialised knowledge of neuroscience, but covers recent advances in our understanding of how the brain represents space.

S3D Dashboard by Florian Weidner Pdf

Over the last decades, the interior of cars has been constantly changing. A promising, yet unexplored, modality are large stereoscopic 3D (S3D) dashboards. Replacing the traditional car dashboard with a large display and applying binocular depth cues, such a user interface (UI) could provide novel possibilities for research and industry. In this book, the author introduces a development environment for such a user interface. With it, he performed several driving simulator experiments and shows that S3D can be used across the dashboard to support menu navigation and to highlight elements without impairing driving performance. The author demonstrates that S3D has the potential to promote safe driving when used in combination with virtual agents during conditional automated driving. Further, he present results indicating that S3D navigational cues improve take-over maneuvers in conditional automated vehicles. Finally, investigating the domain of highly automated driving, he studied how users would interact with and manipulate S3D content on such dashboards and present a user-defined gesture set.
