Perceived Egocentric Distances in Real, Image-Based, and Traditional Virtual Environments

In virtual environments, perceived egocentric distances are consistently underestimated when compared to the same distance judgments in the real world. The research presented in this paper explores two possible causes for the compressed distance perception in virtual environments: (1) real-time computer graphics rendering, and (2) immersive display technology. Our results show there is a signif...

Gaze-Dependent Depth-of-Field Effect Rendering in Virtual Environments

This paper presents gaze-dependent depth-of-field (DOF) rendering setup, consisting of high frequency eye tracker connected to a graphics workstation. A scene is rendered and visualised with the DOF simulation controlled by data captured with the eye tracker. To render a scene in real-time, the reverse-mapped z-buffer DOF simulation technique with the blurring method based on Poisson disk is us...

An Experimental Comparison of Perceived Egocentric Distance in Real, Image-Based, and Traditional Virtual Environments using Direct Walking Tasks

In virtual environments, perceived egocentric distances are often underestimated when compared to the same distance judgments in the real world. The research presented in this paper explores two possible causes for this reduced distance perception in virtual environments: (1) real-time computer graphics rendering, and (2) immersive display technology. Our experiment compared egocentric distance...

Towards Real-Time Interactive Visualisation in Virtual Environments: A Case Study of Q-SPACE

Virtual Environments present opportunities for novel interaction with and visualization of abstract data. However, the inherent difficulties of rendering three dimensional environments, as well as bottlenecks in traditional virtual reality systems make real-time manipulation of realistic volumes of data difficult. We present an architectural solution that addresses many of these problems, and Q...
