We propose Specimen Box, an interaction technique that allows world-fixed display (such as CAVEs) users to naturally hold a plausible physical object while manipulating virtual content inside it. This virtual content is rendered based on the tracked position of the box. Specimen Box provides the weight and tactile feel of an actual object and does not occlude rendered objects in the scene. The end...
Here we explore a visual display technique for low frame rate virtual environments called low persistence (LP). This involves displaying the rendered frame for a single display frame and blanking the screen while waiting for the next frame to be generated. To gain greater knowledge about the LP technique, we have conducted a user study to evaluate user performance and learning during a dynamic target...
User performance in virtual environments with degraded visual conditions due to low frame rates is an interesting area of inquiry. Visual content shown in a low frame rate simulation has the quality of the original image, but persists for an extended period until the next frame is displayed (so-called high persistence-HP). An alternative, called low persistence (LP), involves displaying the rendered...
In virtual reality applications, there is an aim to provide real time graphics which run at high refresh rates. However, there are many situations in which this is not possible due to simulation or rendering issues. When running at low frame rates, several aspects of the user experience are affected. For example, each frame is displayed for an extended period of time, causing a high persistence image...
The increasingly widespread availability of high-accuracy terrain models is revolutionizing our understanding of historic landscapes across the globe, yet much of this inherently 3D data is viewed and analyzed using 2D Geographical Information System (GIS). The ability to explore the environments in a more immersive way that takes advantage of the full data content is advantageous for professionals...
