Usability study of the virtual test bed and distributed simulation

Improving the usability of a distributed simulation system (DSS) test bed is the focus of this paper. An introduction to the field of usability is given, followed by a discussion of the characteristics of DSSs. Then the usability of DSSs is considered. The virtual test bed (VTB), a sample DSS we have improved the usability of, is described. The methodology used to improve the VTB´s usability is given. With the goal of improving usability for end users, prototyping of a graphical user interface is discussed; both software and paper prototypes are considered. Lessons learned provide insights into problems we encountered. Research on important aspects of DSSs that affect usability is reflected in a table that summarizes key issues. Our anticipated future research in this area is also discussed.
