ABSTRACT:
Scrolling of page oriented or continuous information is initiated or controlled based on where a viewer's eyes are looking as detected by an eyetracker. Scrolling rate can be gradually changed based on how far down a screen of text a reader has read, so that a reader will not run out of text. Selection of objects to scroll is also accomplished using the eyetracker. Page and scroll objects can be defined on the display and activated by a user's gaze. A change of background color may be used to make a user aware that a page change is imminent.
