Abstract

This thesis describes user interface and visualization components in the problem solving
environment "Site-Specific System Simulator for Wireless System Design" (S4W) developed
by CS and ECE faculty and students at Virginia Tech. S4W integrates visualization and
computational tools with a high level user interface. The objective of this PSE is to improve
the ability of wireless design engineers to design an indoor wireless system through the aid of
various simulation and visualization components. S4W provides engineers with the facility
of thinking in terms of the overall task of designing the system for optimal performance.
They need not to worry about computation, data-management and connectivity issues.
The choice of method for interaction between service logic within a PSE and its user
is always a challenging issue. The selection of user interaction channel is mostly dictated
by the characteristics of the problem domain. For S4W, we chose to build a graphical
user interface as human interaction interface, which was connected to other components
via a high speed Local Area Network (LAN). The other key form of user interaction in
a PSE is the visual representations of the abstract data results of simulations, perceived
as user interface for data. The Complex nature of data sets in the domain of wireless
simulations calls for a customized set of visualization tools. To address the specific needs
of visualizations for S4W, ad hoc visualization tools were developed and integrated into the
graphical user interface. A comparison of the integrated PSE and an earlier collection of
unintegrated tools and scripts is presented.
