USING FBS ONTOLOGY TO ANALYSE AND COMPARE DESIGNERS’ REASONING PROCESSES IN SMM AND AMM DESIGN ENVIRONMENTS: A pilot study with architectural designers
Authors: Shih, Yi Teng ; Sher, Willy ; Taylor, Mark
This paper presents the results of a pilot protocol study of the design behaviour differences of designers. The aim of the study reported in this paper is to understand the similarities and differences in designers’ behaviour using Sequential Mixed Media (SMM) and Alternative Mixed Media (AMM), and how switching between media may impact the design process. Two designers with at least one-year’s professional design experience and with a Bachelor of Design degree, and are competent at both sketching and CAD modelling, participated in the pilot study voluntarily. Video recordings of designers working on different pilot projects were coded utilising Function-Behaviour-Structure (FBS) ontology and interviews of switching were categorised into three types. Preliminary results indicate that switches between sketching and CAD modelling may influence how designers identify problems and develop solutions. In particular, some codes of structure change to documentation when switching from sketching to CAD modelling. These switches are able to integrate both design tools into one design medium.
