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.
