Abstract: A data viewing terminal for displaying graphical indices pointing to elements of a database of information in a way that takes into account properties of the human visual perception system so as to maximize the amount of information that the user can absorb. The system has an interface with a processor that displays the graphical indices as images moving across a viewing screen. The screen is divided into viewing segments, each of which displays graphical indices in motion in a direction predetermined for that segment where the information in at least one pair of adjacent viewing segments moves in anti-parallel directions.
