Improving Computer Simulation Through Use of a Graphical User Interface

Summary Historically, simulation has been performed on large mainframe and minicomputers. These computers were limited in number, expensive, and controlled by a small group of professionals highly trained in the use of these resources. These resources were often difficult to access and use; they were not "user friendly." The appearance of high-speed, high-capacity desktop computers allowed an increasing number of engineers and scientists access to computers and simulators. Because these new resources were often difficult to use and the users were not highly trained, however, many of the problems associated with difficulty of use remained. Graphical User Interfaces (GUI's) have helped solve many of the usage problems. GUI's provide additional capabilities that increase the ability of scientists and engineers to use their computer resources. These capabilities increase the value of simulators by extending usage through increased functionality. The consistency of a well-designed family of simulator GUI's can enhance training effectiveness by increasing familiarity with basic operations, assisting in the validation of data, and improving "help" facilities available to the user.
