Abstract
Abstract Passively tracking a user's eye gaze while the user is browsing a web page and modifying the presentation of the web page to the user based on the tracked gaze. By combining historical information about a user's direction of gaze on individual cached web pages, a browser may be enabled to represent regions of a web page that have been previously glanced at by the user in a modified manner. For example, sections of a web page that a user has previously read or viewed may be represented in a changed form, such as in a different color, brightness, or contrast, for example. In one embodiment, the portions of the web page previously viewed by the user may be represented as “grayed out” so as to be unobtrusive.
