Abstract
In this research, the basic layout pattern which is shown by the operational sequence of the GUI component in the information equipment screen to the navigation of a user's operation was built. First, the GUI screen samples used now were collected. Next, the function of the GUI component was defined. Next, in a screen which performs a certain task, the inclusive relation of those functions was analyzed by the FCA. Finally, the flow of the function was specified from the concept lattice obtained by that analysis.
