Recent scholarship suggests that virtual environments can serve as effective proxies in battling implicit stereotypes. However, existing experimental research has rarely examined the effectiveness of virtual simulations of mental illnesses in inducing empathy to combat stereotypical responses. We report results from a 4-condition, between subjects experiment (N = 112), wherein participants were...

The use of virtual simulation-based training continues to expand, as organizations explore alternative methods to reduce the cost of training. While virtual simulation has been empirically validated to be effective in the transfer of skills to the live environment, what is still unknown is what effect, if any, that an individual’s sense of presence in the simulation has on their performance. In...

The objective of this research is to present a discussion about concepts and steps necessary to develop Virtual Reality environments for simulation and training of medical procedures. Thus, were related the main features of systems found in scientific literature in order to distinguish difficulties in creating virtual simulators, verify results achieved and point out future trends in simulation...

Graphical level of detail (LOD) is a set of techniques for coping with the issue of limited computational resources by reducing the graphical detail of the scene far from the observer. Simulation LOD reduces quality of the simulation at the places unseen. Contrary to graphical LOD, simulation LOD has been almost unstudied. As a part of our on-going effort on a large virtualstorytelling game pop...

Virtual garment design and simulation involves a combination of a large range of techniques, involving mechanical simulation, collision detection, and user interface techniques for creating garments. Here, we perform an extensive review of the evolution of these techniques made in the last decade to bring virtual garments to the reach of computer applications not only aimed at graphics, but als...
