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.
