Abstract :
Stereo displays suffer from crosstalk, an effect that reduces or even inhibits the viewer´s ability to correctly perceive depth. Previous work on software crosstalk reduction focussed on the preprocessing of static scenes which are viewed from a fixed viewpoint. However, in virtual environments scenes are dynamic, and are viewed from various viewpoints in real-time on large display areas. In this paper, three methods are introduced for reducing crosstalk in virtual environments. A non-uniform crosstalk model is described, which can be used to accurately reduce crosstalk on large display areas. In addition, a novel temporal algorithm is used to address the problems that occur when reducing crosstalk in dynamic scenes. This way, high-frequency jitter caused by the erroneous assumption of static scenes can be eliminated. Finally, a perception based metric is developed that allows us to quantify crosstalk. We provide a detailed description of the methods, discuss their tradeoffs, and compare their performance with existing crosstalk reduction methods
