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).
Our research on gaze-contingent multi-resolutional displays has
covered several topics:
-
Matching the Drop-Off of
Image Resolution in Gaze-Contingent Multi- Resolutional Displays to
That of Human Visual Resolution
-
The Effects on
Perception and Performance When Image Resolution Drops Below the
Limits of Visual Resolution
-
Matching Image Update
Rates in Gaze-Contingent Multi-Resolutional Displays to the
Temporal Limits of Vision
