| Summary: | 碩士 === 國立交通大學 === 建築研究所 === 93 === In the view of design thinking, Archer (1964) proposed "the operational design model", emphatically emphasizes the relationship between individual design procedures and the feedback behavior. In the view of design media, Tversky (1999) proposed that sketch as a trigger. Drafting has always been applied as a tool to stimulate individual design thinking instead of being an open presentation. The designer employ appropriate methods of presentations as well as feasible materials and construction techniques and gradually transform abstract ideas into concrete building structures while utilizing personal creativities, expertise and experience to develop design (Liu 1996). In brief, conceptual model as a trigger in stimulating design thinking. However, the past studies had merely touched on the use of media in design. What seems to be lacking is the role of trigger via media in design thinking. Therefore, the issue of this research is a study on trigger factors via computer media. The objective of this research is to explore the trigger capacity via computer media in sketching-phase and conceptual-model-phase.
This study consists of three steps as following. First, a hypothesis is suggested; while designers generate ideas using computer media, different media can trigger different reaction. Secondly, cognitive experiments are conducted to examine the trigger capacity via computer media. Lastly, the revised coding system is conducted with the action categories by Suwa, Pucell, and Gero (1998). The analysis material is primarily the process of the visual data and the verbal data. Further confirms the different media to be able to provide differently triggers. As a consequence, three phenomena about the role of trigger are found.
