ÖgeAn architectural design method using rank-based interactive evolutionary algorithm(Graduate School, 2023-04-27) Dedeler, Elif Gamze ; Bittermann, Michael Stefan ; 523191007 ; Architectural Design ComputingEvolutionary algorithms are a stochastic search methodology that has been widely researched and used in engineering design and has recently found applications in other design fields. In each context, their aim is to maximize the satisfaction of one or more goals, based on calculated satısfaction of the goals. There are tasks, such as architectural design, where calculating satisfaction is problematic, because goals involve experiential qualities, such pleasure, comfort, meaning, etc. Although this creates a bottleneck for computational treatment, a person can evaluate experiential qualities by aesthetic judgment or some reasoning. Interactive evolutionary algorithm (IEA) is a form of evolutionary computation designed to utilize information provided through human subjective assessments. Aesthetic judgment is subjective measurement of pleasure resulting from a perception. In this respect, aesthetic judgment takes place in real-time and without conceptual abstraction. Because there is no abstraction in this type of judgment, the knowledge a designer can exercise when he/she faces multiple alternative designs, is determining which design is more pleasant to perceive compared to another one. Determining the exact score of each design on some absolute scale is problematic due to the subjective nature of judgment, ı.e. the absence of a consensus about such a scale. Therefore, this study proposes a design method based on an interactive evolutionary algorithm using a non-dominated sorting method that is well-known in the context of multi-objective evolutionary algorithm. In this method, the fitness value is assigned based on people's subjective preferences, allowing to gradually approach to the best design solution based on one's aesthetic judgment. The method developed is applied to the case of a theater named Schauspielhaus designed by Jorn Utzon (1918-2008) in Zurich, Switzerland. The ceiling module, one of the conspicuous of Utzon's design, was modeled and parameterized in Grasshopper. The convergence behavior of the proposed algorithm during the design process was examined throughout 364 design generations by 25 participants. The results indicate that the proposed algorithm is able to integrate the aesthetic preferences of the designers. The study also yields hints about the richness of the resulting information produced by the interactivity, by applying non-parametric statistical tests as well as unsupervised machine learning for design knowledge elicitation.

ÖgeDREAMSCAPE: Use of virtual reality in architectural design & education(Graduate School, 2023-03-24) Doma, Oğuz Orkun ; Şener, Sinan Mert ; 523142004 ; Architectural Design ComputingVirtual reality (VR) technology has attracted increasing interest as a medium for architectural design and experience, enabling users to interact with immersive digital environments that simulate reality in real-time. This study introduces the DREAMSCAPE framework, which adopts a direct manipulation approach and emphasizes embodiment, experience, and manipulation activities during the design process. This framework aims to facilitate intuitive interactions beyond the preconceptions of traditional computer-aided design (CAD) systems. To demonstrate and establish the framework, an experimental VR design tool named Dreamscape Bricks VR has been designed and developed for this study in Unreal Engine 4, employing LEGO bricks as base components to create a high-fidelity interactive design environment. To compare the design processes between physical and virtual mediums, design experiments were conducted with a group of 14 participants consisting of architects, graduate students, and undergraduate design students. Each participant was tasked with designing a shelter and a pavilion, once using physical LEGO bricks (in situ) and once using the Dreamscape Bricks VR tool (in virtuo). The design processes in both the physical and virtual mediums were analyzed through video recordings of the participants, retrospective think-aloud protocols, and post-experiment surveys. The participants' cognitive design processes were evaluated using the Function-Behavior-Structure (FBS) framework and infographic entropy analysis, while the Embodiment-Experience-Manipulation (EEM) taxonomy was developed to conduct a deeper analysis of the design activities observed in the session recordings that could not be reflected in the retrospective self-reports. The results revealed comparably rich cognitive design processes in both mediums. However, the VR medium exhibited significantly higher levels of embodiment and experience activities. Notably, manipulating user scale within the VR environment introduced unique design opportunities, facilitating a dynamic exploration of spatial design at various scales, which is unavailable in the physical medium. Overall, this research offers guidelines for VR design tool development, focusing on more intuitive, immersive, and user-friendly experiences. The findings of the design experiments provide insights into the use of VR and metaverse environments in architectural design and education. By offering a more immersive design experience through designing while being present inside, similar to dreamscapes, VR has the potential to unlock novel creative opportunities and enhance the design process.
