GUI prototype generation by merging use cases

In developing an application software, it is important to pay attention to end-users' viewpoints. In particular, in designing Graphical User Interfaces (GUIs), it is effective to develop a prototype and to show it to end-users in order to reflect end-users' viewpoints, because the design of the GUI strongly affects the usability of the application. Use case diagrams and scenarios are described from end-users' viewpoints, so it is considered that GUIs reflecting end-users' viewpoints can be developed using use case diagrams. In this paper, we propose a method for generating GUI prototypes from given use case diagrams and scenarios. GUI prototypes can be generated based on the extracted control structure with appended simple widget information.
