A Graphical Specification System for User-Interface Design
July/August 1990 (vol. 7 no. 4)
pp. 12-20

An environment for creating user interfaces for embedded systems, called the graphical specification system (GSS), is presented. GSS combines graphical and minimal low-level textual specification with a prototyping capability for rapid user-interface design and evaluation. It is part of a larger embedded systems project at Lockheed, called Express. The user interface components, display components, user-machine interaction, interface-application interaction, and executive component are discussed. Two scenarios, developed with GSS tool prototypes, demonstrate how some GSS tools function. One is the construction of a display with two pairs of gauges, one Cartesian and one polar. The other is the design of a display for submarine tracking.
