Tools For Iterative User Interface Design: Ui-Tester And Ost

A computer-aided iterative design environment is proposed. A usability testing tool “UI-tester” and a user interface design tool “OST” are integrated so that iterative design programs can be effectively implemented in the early stage of product development without usability expertise. A feasibility study being conducted on an ongoing facsimile product development project in this environment gives data showing that common erroneous pattern extraction functions of UI-tester are applicable for identifying user interface problems, and that user interface redesigns are completed without additional delays in the product development cycle.
