SUIT: Software user interface design tool

SUIT, a software user interface design tool, is a visualization and prototyping tool that facilitates collaboration between programmers and usability personnel by offering multiple views of a user interface design. This paper describes the roles of different views on prototypes in user interface design, then explains how SUIT generates multiple views with a node-flow model of object-based and event-driven programs. The node-flow model allows visualization of programs with graphical user interfaces, which make it easy for people not skilled in window programming to find usability problems.
