Gaze-Contingent Multi-Resolutional Displays
There are many types of single-user computer displays for which people want or need very high image resolution, large fields of view, and fast image updates, for example virtual reality, simulators, video telephones, teleoperation, telemedicine, or remote piloting. Unfortunately, these combined demands often exceed the available processing resources or transmission bandwidth. One way to economize on resources and bandwidth in such applications is to use a gaze-contingent multi-resolutional display—a display in which you put high resolution information only where the user is looking at each moment, and lower resolution everywhere else, by using multi-resolutional images and gaze-tracking. Our research on this topic investigates the effects of varying the spatial and temporal dimensions of gaze-contingent multi-resolutional displays on users?perception and visual task performance. Together with Eyal Reingold and David Stampe at the University of Toronto, and George McConkie at the University of Illinois, we have published a review paper on gaze-contingent multi-resolutional displays synthesizing research across the fields of electrical engineering, computer science, vision science, and psychology, and provided a general framework within which research across these areas can be integrated, evaluated, and guided (Reingold, Loschky, McConkie & Stampe, 2003).
