The U.S. Army Research Institute is investigating requirements for using Virtual Environments (VE) in training dismounted soldiers. This experiment investigated full body representation (generic) versus a hand linked pointer on movement performance in an office building interior during a search task. The search task was used as a representative dismounted soldier activity in urban environments. The VE used a biocular Head Mounted Display (HMD) with head coupled and body referenced movement control. Sensors enabled participants to walk through the VE while performing the search task in six repeated trials. Movement time and number of collisions during discrete phases of the search task revealed no significant differences found between full body and pointer representations, although significant improvement was found over repeated trials. Field of view is discussed as a possible intervening aspect. A Simulator sickness questionnaire (SSQ) was administered before, during, immediately after the experiment, and after a recovery period. Significant changes in the SSQ were found over the course of the experiment, but were not related to the body representation condition. The results indicate a rapid onset of symptoms followed by some adaptation to the VE, and rapid recovery. The Immersive Tendencies Questionnaire administered pre-experiment, and the Presence Questionnaire administered post-experiment, were not significantly related to the body representation conditions.

With contributions from a collection of authors consisting of many recognizable experts in the field of virtual and adaptive environments, as well as many up and coming young researchers, this book illustrates the many ways in which psychological science contributes to and benefits from the increased development and application of these nascent systems. Discussing issues from both a user- and technology-based standpoint, the volume examins the use of human perception, cognition, and behavior. The book builds a foundation on the assumption that these systems are first and foremost human-centered technologies, in that their purpose is to complement and extend human capabilities across a wide variety of domains.

This thesis investigates human performance differences on maneuvering tasks in virtual and real spaces when a natural locomotion technique is used as opposed to an abstraction through a device such as a treadmill. The motivation for the development of locomotion devices thus far has been driven by the assumption that a The "perfect" device will result in human performance levels comparable to the real world. This thesis challenges this assumption under the hypothesis that other factors beyond the locomotion device contribute to performance degradation. An experiment was conducted to study the effects of these other factors. The experiment studied sidestepping, kneeling, looking around a corner, and backward movement tasks related to a building clearing exercise. The participants physically walked through the environment under all conditions. There were three treatments: real world (no display, physical objects present), virtual world (head- mounted display, no physical objects), and real and virtual world combined (head-mounted display, physical objects present). The results suggest that performance and behavior are not the same across conditions with the real world condition being uniformly better than the virtual conditions. This evidence supports the claim that even with identical locomotion techniques, performance and behaviors change from the real to the virtual world.

Since 1992, when it began as the "Medicine Meets Virtual Reality" conference, NextMed/MMVR has been a forum for researchers utilizing IT advances to improve diagnosis and therapy, medical education, and procedural training. Scientists and engineers, physicians and other care providers, educators and students, military medicine specialists, futurists, and industry: all come together with the shared goal of making healthcare more precise and effective. This book presents the proceedings of the 20th NextMed/MMVR conference, held in San Diego, California, USA, in February 2013. It covers a wide range of topics: simulation, modeling, imaging, data visualization, haptics, robotics, sensors, interfaces, plasma medicine, and more. Key applications include simulator design, information-guided therapies, learning tools, mental and physical rehabilitation, and intelligence networking. During the past two decades, healthcare has been transformed by progress in computer-enabled technology, and NextMed/MMVR has played a prominent role in this transformation.

"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.

In 1988, the NATO panel governing human sciences (Panel 8 on Defence Applica of Human and Bio-Medical Sciences) established a Research Study Group to synthe tions size information relevant to Advanced Technologies Applied to Training Design. During its first phase, the RSG established an active exchange of information on advanced tech nologies applied to training design and stimulated much military application of these tech nologies. With the increased emphasis on training throughout the alliance, Panel 8, during its April 1991 meeting decided to continue with Phase II of this RSG focusing in the area of advanced training technologies that were emerging within the alliance. In order to ac complish its mission, the RSG held a series of workshops. Leaders in technology and training were brought together and exchanged information on the latest developments in technologies applicable to training and education. This volume represents the last in a se ries based on the NATO workshops. In Part One, it details findings from the last work shop, Virtual Reality for Training; and in Part Two, we provide a summary perspective on Virtual Reality and the other emerging technologies previously studied. These include computer-based training, expert systems, authoring systems, cost-effectiveness, and dis tance learning. It is a natural extension to proceed from learning without boundaries to virtual envi ronments. From the extended classroom to the individual or team immersion in a distrib uted, virtual, and collaborative environment is an easy conceptual step.

This Handbook, with contributions from leading experts in the field, provides a comprehensive, state-of-the-art account of virtual environments (VE). It serves as an invaluable source of reference for practitioners, researchers, and students in this rapidly evolving discipline. It also provides practitioners with a reference source to guide their development efforts and addresses technology concerns, as well as the social and business implications with which those associated with the technology are likely to grapple. While each chapter has a strong theoretical foundation, practical implications are derived and illustrated via the many tables and figures presented throughout the book. The Handbook presents a systematic and extensive coverage of the primary areas of research and development within VE technology. It brings together a comprehensive set of contributed articles that address the principles required to define system requirements and design, build, evaluate, implement, and manage the effective use of VE applications. The contributors provide critical insights and principles associated with their given area of expertise to provide extensive scope and detail on VE technology. After providing an introduction to VE technology, the Handbook organizes the body of knowledge into five main parts: *System Requirements--specifies multimodal system requirements, including physiological characteristics that affect VE system design. *Design Approaches and Implementation Strategies--addresses cognitive design strategies; identifies perceptual illusions that can be leveraged in VE design; discusses navigational issues, such as becoming lost within a virtual world; and provides insights into structured approaches to content design. *Health and Safety Issues--covers direct physiological effects, signs, symptoms, neurophysiology and physiological correlates of motion sickness, perceptual and perceptual-motor adaptation, and social concerns. *Evaluation--addresses VE usability engineering and ergonomics, human performance measurement in VEs, usage protocols; and provides means of measuring and managing visual, proprioceptive, and vestibular aftereffects, as well as measuring and engendering sense of presence. *Selected Applications of Virtual Environments--provides a compendium of VE applications. The Handbook closes with a brief review of the history of VE technology. The final chapter provides information on the VE profession, providing those interested with a number of sources to further their quest for the keys to developing the ultimate virtual world.
