Abstract

The organization of a menu can significantly affect user response time when selecting targets from that menu. Previous empirical studies have used laboratory tests to suggest menu design rules that can optimize user response. This study applied the design rules to a menu used for display selection on an Energy Management System. In such a study, the total number of menu targets and the relationships among them is not variable, so some compromises must be made when applying the rules. This study produced a new menu that had measurable improvement in user response time over the existing menu. Design rules regarding grouping of targets and methods of organization were successfully applied during the menu redesign.
