    Abstract: User input buttons are displayed as part of a graphical user interface by showing the buttons as multiple oval shapes and including shading and highlighting to indicate different states of the buttons. The buttons appear to the user as three dimensional simulated mechanical buttons because of the shape, shading, and temporal states used to represent them. States of the buttons include inactive, active, entered and pressed, each state having its own bitmap image to represent it on the computer display.
