Users may derive new classes by defining views based on the current database contents. Some virtual classes are classified as brothers of existing classes, and others are either superclasses or subclasses of existing base and virtual classes. A base class is defined directly by the user using class definition constructs. A virtual class is classified as a brother of another class if it is deriv...

This talk discusses our investigation into an objective presence measure. In our experiment, we investigated the correlation among a post-experiment presence questionnaire, human peripheral response (electrodermal activity and skin temperature), and a behavioral-presence questionnaire. Our findings show that the measures do correlate and have use as a potential objective surrogate for subjectiv...

When we move, the visual direction of objects in environment can change substantially. Compared with our understanding depth perception, problem system faces computing this is relatively poorly understood. Here, tested extent to which participants’ judgments could be predicted by standard cue combination rules. Participants were virtual reality using a head-mounted display. In simulated room, t...

background: historically, operating room (or) has always been considered as a stand-alone trusted platform for surgical education and training.however, concerns about financial constraints, quality control, and patient safety have urged the surgical educators to develop more cost-effective, surgical educational platforms that can be employed outside the or. furthermore, trained surgeons need to...

Immersive virtual environment technology is increasingly used by psychologists as a tool for researching social influence in realistic, yet experimentally controllable, settings. The present study demonstrates the validity and reliability of facial electromyography as a marker of affect in immersive virtual environments and further shows that the mere presence of virtual humans is enough to eli...

Four experiments investigated the conditions contributing to sensorimotor alignment effects (i.e., the advantage for spatial judgments from imagined perspectives aligned with the body). Through virtual reality technology, participants learned object locations around a room (learning room) and made spatial judgments from imagined perspectives aligned or misaligned with their actual facing direct...

BARLOW, STEVEN TODD. Spatial Knowledge Acquired Through Navigation In A LargeScale Virtual Environment. (Under the direction of Sharolyn Converse.) The effects of changes in elevation, route distance, route complexity, and non-spatial information on memory for a virtual environment were investigated. Thirty college students learned the layout of a two-story virtual environment through a series ...

This paper describes a method to visualize and localize the sound that is simulated within a virtual environment using beamforming. The use of an acoustic camera along with noise image software as a short introduction to beamforming method is demonstrated. Furthermore, the transition from the three-dimensional sound recording to the three-dimensional virtual acoustic mapping, visualization and ...

— We preformed two studies to investigate the cognitive effects related to two important dimensions of virtual environment systems: travel technique and display. Options for both elements vary significantly in quality and cost. Our first study examined four different methods of travel in an virtual environment and their effect on cognition. Our second study examined the effects of large display...

The goal of this study is to develop a “virtual collaborator” as a new type of human interface environment. The virtual collaborator is an intelligent agent realized in VR space, who can communicate naturally with human like humans do with each other. As the first step of this study, the authors have constructed a prototype virtual collaborator who can behave just like plant operator in the con...
