Book Effects of Display Type on Performance in Virtual Environments

Download or read book Effects of Display Type on Performance in Virtual Environments written by and published by . This book was released on 1996 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research was conducted as part of a program to determine interface requirements for enabling dismounted soldiers to train in Virtual Environments (VEs). We compared different VE display devices in terms of their effects on task performance, skill acquisition, and side effects. Forty-eight college students completed a series of visual and psychomotor tasks, a subset of the Virtual Environment Performance Assessment Battery (VEPAB), using either a Head-mounted Display (HMD), a head-tracked boom-mounted display, or a standard computer monitor. Performance on vision tasks was sensitive to differences in display devices and to individual differences. Visual acuity scores were ordered according to estimates of the resolution of the displays, but were worse than what would he predicted from the resolution estimates. In comparison to real-world performance, distance and height estimation in the VEs varied greatly across participants, especially with the HMD. Motor tasks had high reliability, demonstrated small but significant practice effects, and were correlated with participants' use of computers and video games. Unexpectedly, even the standard monitor group showed a significant increase in simulator sickness scores. The VEPAB tasks should prove useful in the future when design tradeoffs must be made in the process of developing training system prototypes.

Book The Effects of Display Type and Spatial Ability on Performance During a Virtual Reality Simulation

Download or read book The Effects of Display Type and Spatial Ability on Performance During a Virtual Reality Simulation written by Fernando Manrique and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the effects of display type and spatial ability level on performance during three trials of a virtual reality (VR) simulation. Seventy-six Air Force Reserve Officer Training Corps cadets were identified as having high or low spatial ability level. Subjects used either a helmet mounted display or a standard computer monitor to perform a VR simulation. The study examined the effects of display type, spatial ability, and number of trials on simulation performance, performance strategy, discomfort level, display characteristics and attitude. Results indicated that subjects with high spatial ability performed significantly better on the simulation than subjects with low spatial ability. Performance results revealed a significant interaction between spatial ability level and trial. Separate analyses for each spatial ability group showed that the performance of high spatial ability subjects improved significantly from trial to trial. The performance of low spatial ability subjects did not significantly improve over time. There were no significant performance differences between subjects that wore the head mounted display versus subjects that did the simulation on a standard computer monitor. Results for performance strategy suggested that high spatial ability subjects used more effective strategies during the simulation than low spatial ability subjects. Exploratory data analysis indicated that performance strategy was a stronger predictor of performance than spatial ability. Discomfort survey results indicated that subjects who used the head mounted display reported significantly higher levels of cold sweating and difficulty focusing than subjects who used the standard computer monitor. Head mounted display subjects also rated display resolution significantly lower than computer monitor subjects. High spatial ability subjects benefited significantly more from practice than low spatial ability subjects.

Book Handbook of Virtual Environments

Download or read book Handbook of Virtual Environments written by Kelly S. Hale and published by CRC Press. This book was released on 2002-01-01 with total page 1273 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Virtual Environments for Dismounted Soldier Training and Performance

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.

Book Effect of a Body Model on Performance in a Virtual Environment Search Task

Download or read book Effect of a Body Model on Performance in a Virtual Environment Search Task written by Michael J. Singer and published by . This book was released on 1998 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
