Book Description
This paper investigates the perception of distance in virtual environments. It describes an experiment designed to determine observers' ability to make use of error corrective feedback to improve the accuracy of judgments of absolute egocentric and exocentric distances. Observers viewed objects at varying distances in a virtual environment and gave their estimates of distance through a blindfolded walking task, in which observers walked the distance to or between previously viewed targets. Feedback training was provided to observers based on experimental condition. The effect of feedback was quite specific. Receiving egocentric feedback significantly improved only observers' egocentric distance estimates, and exocentric feedback improved only people's exocentric distance estimates. This improved ability to estimate egocentric as well as exocentric distances persisted for at least one week's time.

Book Description
Technologische Fortschritte in der Computergrafik, dem dreidimensionalen Scannen und in Motion-Tracking-Technologien haben zu einem erhöhten Einsatz von Selbst-Avataren in immersiven virtuellen Realitäten (VR) beigetragen. Selbst-Avatare werden zum Beispiel in den Bereichen Visualisierung und Simulation, aber auch in klinischen Anwendungen oder für Unterhaltungszwecke eingesetzt. Deshalb ist es wichtig neue Erkenntnisse über die Wahrnehmung des eigenen Körpers, des Selbst-Avatars und der räumlichen Wahrnehmung des Benutzers zu gewinnen, sowie den Einfluss des Selbst-Avatars auf die räumliche Wahrnehmung in der virtuellen Welt zu untersuchen. Mit Hilfe von moderner VR-Technologie habe ich untersucht wie Veränderungen des Selbst-Avatars die Wahrnehmung des eigenen Körpers und des Raumes verändern. Die Ergebnisse zeigen, dass Selbst-Avatare nicht genau die gleichen Dimensionen wie der Körper des Benutzers haben müssen, damit sich der Benutzer mit seinem Selbst-Avatar identifizieren kann.

Book Description
The majority of research on human perception and action examines sensors and effectors in relative isolation. What is less often considered in these research domains is that humans interact with a perceived world in which they themselves are part of the perceptual representation, as are the positions and actions (potential or ongoing) of other acti

Book Description
"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.

Book Description
The accurate perception and estimation of distance is an important element of many military tasks. It is necessary for orienting oneself on the battlefield, for making optimal use of terrain features during navigation, and for judging the distance from one point to another. It is also a component of both route and configuration knowledge and acquisition. In order to maximize transfer from Virtual Environment (VE) to the real world, it is important to develop an understanding of the capabilities and limitations of this new training medium. Toward that end, the present study sought to gain insight about the conditions affecting distance estimation of VEs. The purpose of this research is to examine factors that influence the perception of distance in VEs. Two experiments were designed to investigate the relative effects of such factors on distance estimates of a stationary observer positioned at near and medium distances from an object. Factors found to improve distance estimates in these experiments will be incorporated into the design of VEs for subsequent investigations.
