abstract:A computer icon is a pictogram displayed on a computer screen in order to help user navigate a computer system or mobile device in a similar way traffic signs are used to help a driver navigate traffic; one of the most notable icon designers, Susan Kare was quoted saying "good icons should be more like road signs than illustrations, easily comprehensible, and not cluttered with extraneous detail".
The pink, rectangular icon on the computer screen representing the progress of PATH train 5780 blinked, as the cars rolled out on the westbound tracks from the World Trade Center station.
