Visual Fidelity Optimization of Displays

Abstract

The visual experience afforded by digital displays is not identical to our perception of the genuine real world. Display resolution, refresh rate, contrast, brightness, and color gamut neither match the physics of the real world nor the perceptual characteristics of our Human Visual System. With the aid of new algorithms, however, a number of perceptually noticeable degradations on screen can be diminished or even completely avoided.

ICG Dome

Featuring more than 10 million pixels at 120 Hertz refresh rate, full-body motion capture, as well as real-time gaze tracking, our 5-meter ICG Dome enables us to research peripheral visual perception, to devise comprehensive foveal-peripheral rendering strategies, and to explore multi-user immersive visualization and interaction.

Reality CG

Scope of "Reality CG" is to pioneer a novel approach to modelling, editing and rendering in computer graphics. Instead of manually creating digital models of virtual worlds, Reality CG will explore new ways to achieve visual realism from the kind of approximate models that can be derived from conventional, real-world imagery as input.

Simulating Visual Perception

The aim of this work is to simulate glaring headlights on a conventional monitor by first measuring the time-dependent effect of glare on human contrast perception and then to integrate the quantitative findings into a driving simulator by adjusting contrast display according to human perception.
