Integrating methods of human-computer interface design with structured systems development

Abstract

Various methods for specification and design of the human-computer interface have been proposed but practice of such methods is not widespread. Possible reasons for this may be the lack of integration of human-computer interface design with software engineering and the specialized nature of HCI methods. A method of interface design is proposed which integrates the development of the human-computer interface with structured systems analysis and design. The method covers task and user analysis, interface specification and dialogue design. A case study of a library system is used to illustrate the method which is discussed in relation to different approaches that have been adopted for interface specification and design. It is argued that software design methods should cover all aspects of process design and the human-computer interface.
