High-quality rendering of both audio and visual material properties is very important in interactive virtual environments, since convincingly rendered materials increase realism and the sense of immersion. We studied how the level of detail of auditory ...

An experiment was conducted to investigate whether human observers use knowledge of the differences in focus of attention in multiparty interaction to identify the speaker amongst the meeting participants. A virtual environment was used to have good ...

We report on three experiments that investigate the efficacy of a new type of interface called a virtual verbal display (VVD) for nonvisual learning and navigation of virtual environments (VEs). Although verbal information has been studied for route-...

This article presents a method for automating rendering parameter selection to simplify tedious user interaction and improve the usability of visualization systems. Our approach acquires the important/interesting regions of a dataset through simple user ...

It is still an unsolved problem how to optimally simulate self-motion using motion simulators. We investigated how a forward acceleration can be simulated as believably as possible on a hexapod motion platform equipped with a projection screen.

Human ...

Based on concepts of the human visual system, computational visual attention systems aim to detect regions of interest in images. Psychologists, neurobiologists, and computer scientists have investigated visual attention thoroughly during the last ...

Previous work in real and virtual settings has shown that the way in which we interact with objects plays a fundamental role in the way we perceive them. This article uses multidimensional scaling (MDS) analysis to further characterize and quantify the ...
