Matching the Drop-Off of Image Resolution in Gaze-Contingent Multi- Resolutional Displays to That of Human Visual Resolution
The chief goal for designers of gaze-contingent
multi-resolutional displays has been to create display images that have
removed all the information that users cannot perceive, yet the images
are not perceptibly different from full high-resolution images. To do
this, you must create images in which image resolution drops off with
distance from the center of vision at the same rate that human visual
resolution drops off. Our work on this topic, is the most thorough
perception and performance investigation of this issue to date
(Loschky, McConkie, Yang & Miller, 2005), and provides the first
rigorous existence proof of a gaze-contingent multi-resolutional
display that maximizes savings while being imperceptibly different from
a constant high-resolution image. It also provides the first estimate
of the limits of visual resolution in freely viewed natural scenes,
thus providing a basis for predicting what information in different
parts of the visual field are available to affect scene perception.
This work is in collaboration with Jian Yang and Michael Miller of
Eastman Kodak, George McConkie at the University of Illinois.
