Explore patterns of human-computer interactions in parametric design environments
Current literature shows that there is a lack of empirical evidence support the understanding of human-computer interaction (HCI) process in parametric design environments (PDEs). Parametric design is anew digital design method increasingly applied in architecture, and characterized by parametric relationshipcontrol, rule algorithm design and multiple solution generation. The dynamic nature of parametric designindicates frequent interactions between designers and design environments. Therefore, we are wondering if thereare particular designers’ behavior patterns of HCI in PDEs. To explore the issue, this study proposes a pilot studyin which two students are involved to complete a design task using parametric tools. Furthermore, method of protocol analysis is applied to analyze the video-recorded data of their design processes. Based on Schön’s studyon designers’ cognitive behavior (“reflection in action” and “seeing-moving-seeing”), we develop a coding scheme for analyzing designers’ behavior from three levels: intention level, action level and perceptual level. During HCI process in PDEs, designers’ activities transfer among these three levels. For the intention level,Gero’s FBS model is introduced to identify designers’ thinking processes: FBS model has been suggested to be ableto capture most of the meaningful design processes and indicate clear transition between design events. For theaction level, both geometry modeling activities and specific actions happened in PDEs are categorized in order toanalyze the action happened. Perceptual level is suggested to be the accumulation of generating new intentions,which plays important role in the process of interaction between designers and PDEs. All of the three levelscontain two types of activities: design knowledge based and rule algorithm based. Through protocol analysis, some interaction results and patterns of inspiring and reflecting behavior is identified and discussed.
