|Abstract:||The goal of human factors has been to ensure that the system is both usable and useful. However, many of the valuable sources of human factors advice for the user-interface designers are too technical for the non-specialist in human factors (the computer professionals). To them, the human factors is an opaque and complex subject. What is needed to bridge this gap is a set of methods / tools embedding the underlying principles / guidelines / specific rules of user-interface design. Since most of the design guidelines and specific rules cannot be implemented effectively by algorithmic programming technique, expert systems technology was employed by storing design guidelines and specific rules into knowledge bases. In this dissertation, I have developed a prototype rule-based expert system, the "Human Factors Intelligent Assistant (HFIA)" incorporating three design guidelines (data order, data grouping and clutter) for the design of display layout of textual information. The user-interface designer only needs to organize and break down the data order and data grouping requirements for the arrangement of a given list of items, and specifies the requirements as input knowledge to the HFIA. The HFIA will give an optimal recommendation on how to arrange the given list of items that can enforce the three design guidelines optimally.|
