Blur in images can create the sensation of depth because it emulates an optical property of the eye; namely, the limited depth of field created by the eye's lens. When the human eye looks at an object, this object appears sharp on the retina, but objects at different distances appear blurred. Advances in gaze-tracking technologies enable us to reproduce(More)
Some recent mobile devices have autostereoscopic displays that enable users to perceive stereoscopic 3D without lenses or filters. This might be used to improve depth discrimination of objects overlaid to a camera viewfinder in augmented reality (AR). However, it is not known if autostereoscopy is useful in the viewing conditions typical to mobile AR. This(More)
Using real time eye tracking, gaze-contingent displays can modify their content to represent depth (e.g., through additional depth cues) or to increase rendering performance (e.g., by omitting peripheral detail). However, there has been no research to date exploring how gaze-contingent displays can be leveraged for manipulating perceived color. To address(More)
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(More)
