Gaze-contingent Computational Displays: Boosting perceptual fidelity

Contemporary digital displays feature multi-million pixels at ever-increasing refresh rates. Reality, on the other hand, provides us with a view of the world that is continuous in space and in time. The discrepancy between viewing the physical world and its sampled depiction on digital displays gives rise to perceptual quality degradation. By measuring or estimating where we look, a new breed of gaze-contingent algorithms aim to exploit the way we visually perceive digital images and videos to remedy visible artifacts. This article gives an overview of recent developments in computational display algorithms that enhance perceived visual quality of conventional video footage when viewed on commodity monitors, projectors, or head-mounted displays.
