Abstract
A menu-based interface was designed to provide users with an easy, consistent means for finding and initiating various facilities on a host computer. The interface had to be usable by people of varying levels of skill and experience, using different types of terminals. Three major issues were considered in the design: option selection techniques, display design, and functional organization of the choices within the hierarchy. The ESD-MITRE user system interface (USI) design guidelines on sequence control were applied to the first two issues in this list.
The guidelines were helpful during the design process. They were used to guide the basic design, and to help make decisions as the design was refined. Different guidelines can lead to different designs, so designers must be prepared to decide which requirements and which guidelines are of greatest importance in their particular situations.
