Utility of Gaze-contingent DOF Blur for Depth Perception

Depth-of-Field blur is a by-product of optical systems and its recreation can enhance the realism of images and convey information about size and distance. In this paper we present an approach to create a gaze-contingent DOF blur using pre-rendered scenes created with ray-tracing techniques. The approach has been evaluated in a user study and been shown to increase perceived realism and the perception of depth.
