Abstract

The present invention relates in general to graphical user interfaces (GUI) in computer display systems, and in particular, to the instrumentation of graphical control for task navigation in a GUI system. The present invention provides a method, apparatus, and processing system for performing a step-by-step procedure using a task oriented interface integrated into a single, intuitive, graphical control/display that further controls the user'"'"'s ability to navigate through the steps and prevents the user from attempting to revise irreversible steps. The interface display graphically displays how many steps remain to be completed, and how many steps have already been completed. Additionally, it enables the user to deviate from the predefined order of steps and skip optional steps while compelling the user to complete the required steps. The display also differentially displays the completed steps to indicate which steps can be revised and which cannot.
