Download or read book Effect of Viewing Conditions on Sickness and Distance Estimation in a Virtual Environment written by Jennifer A. Ehrlich and published by . This book was released on 2000 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Virtual Environments for Dismounted Soldier Training and Performance written by and published by . This book was released on 1998 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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. "-- Report documentation page.

Download or read book Why People Get Lost written by Paul A. Dudchenko and published by . This book was released on 2010 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The majority of research on human perception and action examines sensors and effectors in relative isolation.

Download or read book Virtual Reality Designs written by Adriana Peña Pérez Negrón and published by CRC Press. This book was released on 2020-03-12 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtual Reality is not real life. Instead it is life-like creations using computer-generated scenarios. Human behavior is replicated in virtual scenarios, where every detail is controlled by computers, and in situations that can be repeated under the same conditions. Based on technology and design, the user can experience presence. In the virtual world, users are embodied in avatars that represent them and are the means to interact with the virtual environment. Avatars are graphical models that behave on behalf of the human behind them. The user avatar is a proxy that also backs interaction with others, allowing computer-mediated interactions. Analyses directed to understand people’s perceptions, personal and social behavior in computer mediated interactions, comprise a multidisciplinary area of study that involves, among others, computer science, psychology and sociology. In the last two decades a number of studies supported by Virtual Reality have been conducted to understand human behavior, in some cases the implications of the technology, or to reproduce artificial human behavior. This book presents a collection of studies from recognized researchers in the area.
Download or read book S3D Dashboard written by Florian Weidner and published by Springer Nature. This book was released on 2021-08-12 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
