Abstract

To optimize the level of cognition and collaboration during conceptual architectural design phase, novice designers need to employ more flexible and intuitive digital media. This paper presents findings of a feasibility study for using VR 3D sketching interface in order to replace current non-intuitive Computer Aided Design (CAD) tools. We use a sequential mixed method research methodology including a qualitative case study and a cognitive-based quantitative protocol analysis experiment. Foremost, a case study research comprising of ethnography for data collection and artefact and protocol analysis for data analysis was employed in order to understand how novice designers make intuitive decisions. The ethnography study documented the failure of conventional sketching methods in articulating complicated design ideas and shortcomings of current CAD tools in intuitive ideation. Moreover, the subsequent artefact analysis affirmed established constructs about advantages and disadvantages of each medium in providing “solution quality” and also “certainty about correctness of solution”. The case study's findings then became the theoretical foundations for testing the feasibility of using VR 3D sketching interface during design. The latter phase of study evaluated the designers' spatial cognition and collaboration at six different levels: “physical-actions”, “perceptual-actions”, “functional-actions”, “conceptual-actions”, “cognitive synchronizations”, and “gestures”. The results and confirmed hypotheses showed that the utilized tangible 3D sketching interface improved novice designers' cognitive and collaborative design activities. In summary this paper presents and documents the influences of current external representation tools on designers' cognition and collaboration as well as providing the necessary theoretical foundations for implementing VR 3D sketching interface. It contributes towards transforming conceptual architectural design phase from analogue to digital by proposing a new VR design interface. We propose that this transformation to fill in the existing gap between analogue conceptual architectural design process and remaining digital engineering parts of building design process hence expediting digital design process.
