The traditional approach to develop user interface for handset devices has limited flexibility on the UI requirement changes. Once the UI requirement changed, programmers have to change their handcrafted application once again. This change may occur repeatedly until the UI requirement under consideration is satisfied.

Visual-Based Software Construction Methodology has been developed. This methodology helps programmers to develop the user interface for handset devices, and allows programmers to migrate their program to new platform quickly. Based on this methodology, we quest for a generic software framework to incorporate the proposed methodology for developing user interface to alleviate the problems mentioned above.

From our study, there are some similarities exist among user interface and software framework in different handset devices. In this paper, we propose a generic software framework for the system architecture design of handset devices. Specifically, the software framework generated based on the generic software framework will be much easier for maintenance and management compared with the traditional approach. In addition, the software framework hat is instantiated from the generic software framework can be incorporated into the visual requirement authoring system for user interface development. Finally, we design and construct a simulator to demonstrate the applicability and usefulness of the software framework generated by the proposed generic software framework.
