Abstract
Abstract Apparatus, methods, systems and computer program products are disclosed that automatically expands the computer displayed information that interests a computer user. Thus making the information easier for the user to see. The computer detects which area on a display device has the user's interest by using a gaze-tracking device to monitor where the user looks on the display. After determining which area interests the user the invention expands the display of the information in that area.
