US Patent 7350158 Icon display system and method, electronic appliance, and computer program

An icon display system is provided in which an icon train selectable on an icon menu screen is managed by a display icon management table and non-display icon management table to visualize a part of the entire icon train. This is done by disposing the visualized icon train in an orbit while holding the other part of the icon train as invisible icons on the screen and displaying the invisible icons by moving the icon train in the orbit. Some icons are made to visually disappear at a discontinuity of the orbit by moving the icon train in the orbit and the new icons can be made to appear at the discontinuity to the screen. With this system, patterns of individual icons can be prevented from being indiscernible from each other no matter how many icons are set selectable on the display screen.
