title	Growing Shapes with a Generalised Model from Neural Correlates of Visual Discrimination
doi	https://doi.org/https://doi.org/10.1007/978-981-33-4400-6_7

summary	This paper focuses on the application of visual Event-Related Potentials (ERP) in better generalisations for design and architectural modelling. It makes use of previously built techniques and trained models on EEG signals of a singular individual and observes the robustness of advanced classification models to initiate the development of presentation and classification techniques for enriched visual environments by developing an iterative and generative design process of growing shapes. The pursued interest is to observe if visual ERP as correlates of visual discrimination can hold in structurally similar, but semantically different, experiments and support the discrimination of meaningful design solutions. Following bayesian terms, we will coin this endeavour a Design Belief and elaborate a method to explore and exploit such features decoded from human visual cognition.

title	Through the Eyes of (Post-)Flâneurs - Altering rhythm and visual attention in public space in the era of smartphones
doi	https://doi.org/10.52842/conf.ecaade.2020.1.239
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 239-248
summary	In the last decade, rapid penetration of smartphones into our everyday life introduced a new kind of urban wanderer named as the 'post-flâneur'. By navigating through the virtual and physical space with a smartphone, and taking and sharing photographs, post-flâneur walks and experiences the city in novel ways. This paper aims to investigate the effects of smartphone use on the human-environment relationship by comparing post-flânerie with flânerie in public space with a focus on two key indicators: alteration of 1) the visual attention and 2) the walking rhythm. In this regard, ten postgraduate Architecture students are asked to perform flânerie and post-flânerie consecutively in the historical city center of Ghent with an eye-tracker and a smartphone. During the flânerie condition, they walked and experienced the city without using a smartphone. In the post-flânerie condition, they used a smartphone, took pictures and uploaded them to an application. By analyzing the eye-tracker (number and duration of fixations) and the smartphone (location data and geolocated photographs) data, altering rhythm and visual attention during the flânerie and post-flânerie were compared. Preliminary results indicate that flânerie and post-flânerie differ in terms of rhythm and visual attention. The average duration of fixations on the environment were significantly lower in the post-flânerie condition while the average walking rhythm was faster but impeded from time to time. In addition, post-flâneurs' visual attention was on the smartphone during a significant part of the stationary activities which point out to an altered state of public space appropriation. The findings are significant because they reveal the novel spatial appropriations and experiences of the (post)public space -particularly "the honeypot effect" which was more significant in the post-flânerie condition. These observations evoke questions on how designers can rethink public space as a hybrid construct integrating the virtual and the physical.

title	The Impact of Moving through the Built Environment on Emotional and Neurophysiological State - A Systematic Literature Review
doi	https://doi.org/10.52842/conf.caadria.2020.1.641
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 641-650
summary	Despite theoretical evidence about the capabilities of visual properties of space for manipulating inhabitants' emotions, a gap in knowledge exists for empirical studies in controlled environments. Interdisciplinary studies at the intersection of architecture, psychology, and neuroscience can provide robust guidelines and criteria for designers to engineer emotions. Due to the novelty of the field, the theoretical framework for such studies is not well established. Consequently, this paper presents a systematic literature review to find and synthesize recent relevant studies at this intersection. Based on these findings, we will investigate the impact of other visuo-spatial stimuli on emotions in a rigorous way. According to the theories of emotions, manipulation of emotions is linked to oscillations in physiological responses caused by exposure to sensory stimuli. Moreover, there is a consensus that human perception is action-oriented. Therefore, our review focuses on studies that employ biosensors as subjects move in physical or virtual environments.

title	Affective Computing for Generating Virtual Procedural Environments Using Game Technologies
doi	https://doi.org/10.52842/conf.acadia.2020.2.120
source	ACADIA 2020: Distributed Proximities / Volume I: Technical Papers [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95213-0].

summary	Architects have long sought to create spaces that can relate to or even induce specific emotional conditions in their users, such as states of relaxation or engagement. Dynamic or calming qualities were given to these spaces by controlling form, perspective, lighting, color, and materiality. The actual impact of these complex design decisions has been challenging to assess, from both quantitative and qualitative standpoints, because neural empathic responses, defined in this paper by feature indexes (FIs) and mind indexes (MIs), are highly subjective experiences. Recent advances in the fields of virtual procedural environments (VPEs) and virtual reality (VR), supported by powerful game engine (GE) technologies, provide computational designers with a new set of design instruments that, when combined with brain-computing interfacing (BCI) and eye-tracking (E-T) hardware, can be used to assess complex empathic reactions. As the COVID-19 health crisis showed, virtual social interaction becomes increasingly relevant, and the social catalytic potential of VPEs can open new design possibilities. The research presented in this paper introduces the cyber-physical design of such an affective computing system. It focuses on how relevant empathic data can be acquired in real time by exposing subjects within a dynamic VR-based VPE and assessing their emotional responses while controlling the actual generative parameters via a live feedback loop. A combination of VR, BCI, and E-T solutions integrated within a GE is proposed and discussed. By using a VPE inside a BCI system that can be accurately correlated with E-T, this paper proposes to identify potential morphological and lighting factors that either alone or combined can have an empathic effect expressed by the relevant responses of the MIs.

summary	This project aims to continue the correlative study between two fundamental entities of digital architecture: the object and the field. Following periods of experimentations on the ""field"" (materialization of flows of data through animation), the ""field of objects"" (parametricism), the ""object"" (OOO), we investigate the last possible interaction remaining: the ""object-field,"" by merging the formal characteristics of the object with the structural flow of its internal field. This investigation is achieved by exploring the high-resolution features of 3d printing in the design of autonomous architectural objects expressing materiality through topological optimization. The objects are generated by an iterative process of volumetric reduction, resulting in an ensemble of monoliths. Four of them are selected and analyzed through topological optimization in order to extract their internal fields. Next, a series of high-resolution algorithmic systems translate the structural information into 3d printed materiality. Of the four object-fields, one materializes, close to identical, the result of the optimization, giving the keystone to understanding the others. The second one expresses the structural flow through a 1mm voxel system, informed by the optimization, having the effect of stiffening the structure where it is needed and thus generating a new topography on the object. The last two explore the blur that this high-resolution can paradoxically create, with complete integration of the optimal structure in a transparent monolith. This is achieved by a vertex displacement algorithm, and the dissolution of the formal data of the monolith and the structural flows, through the mereological assembly of simple linear elements. For each object-field, a series of drawings was developed using specific algorithmic procedures derived from the peculiarities of their complex geometry. The drawings aim to catalyze coherence throughout the project, where similarities, hitherto kept apart by the multiple materialities, begin to dialogue.

title	A framework for interactive human–robot design exploration
source	International Journal of Architectural Computing vol. 18 - no. 3, 235-253
summary	This study seeks to identify key aspects for increased integration of interactive robotics within the creative design process. Through its character as foundational research, the study aims to contribute to the advancement of new explorative design methods to support architects in their exploration of fabrication and assembly of an integrated performance-driven architecture. The article describes and investigates a proposed design framework for supporting an interactive human–robot design process. The proposed framework is examined through a 3-week architectural studio, with university master students exploring the design of a brick construction with the support of an interactive robotic platform. Evaluation of the proposed framework was done by triangulation of the authors’ qualitative user observations, quantitative logging of the students’ individual design processes, and through questionnaires completed after finishing the studies. The result suggests that interactive human–robot fabrication is a relevant mode of design with positive effect on the process of creative design exploration.

summary	The present project aims to influence the reduction of the urban heat island effect (UHI) by designing sensitive surfaces that respond to changes in temperature. This research presents a scenario with a vision of cities with adaptive designs that is generated from the insertion of elements sensitive to the environment (elements that respond to environmental stimuli). Responsive elements become constant factors in small-scale or large-scale design that transform the way environment is changed to a sensitive and resilient urban environment against possible adverse environmental conditions.

title	Cyborgian Approach of Eco-interaction Design Based on Machine Intelligence and Embodied Experience
doi	https://doi.org/https://doi.org/10.1007/978-981-33-4400-6_8
source	Proceedings of the 2020 DigitalFUTURES The 2nd International Conference on Computational Design and Robotic Fabrication (CDRF 2020)
summary	The proliferation of digital technology has swelled the amount of time people spent in cyberspace and weakened our sensibility of the physical world. Human beings in this digital era are already cyborgs as the smart devices have become an integral part of our life. Imagining a future where human totally give up mobile phones and embrace nature is neither realistic nor reasonable. What we should aim to explore is the opportunities and capabilities of digital technology in terms of fighting against its own negative effect - cyber addiction, and working as a catalyst that re-embeds human into outdoor world. Cyborgian systems behave through embedded intelligence in the environment and discrete wearable devices for human. In this way, cyborgian approach enables designers to take advantages of digital technologies to achieve two objectives: one is to improve the quality of environment by enhancing our understanding of nonhuman creatures; the other is to encourage a proper level of human participation without disturbing eco-balance. Finally, this paper proposed a cyborgian eco-interaction design model which combines top-down and bottom-up logics and is organized by the Internet of Things, so as to provide a possible solution to the concern that technologies are isolating human and nature.

title	Short Stack
source	ACADIA 2020: Distributed Proximities / Volume II: Projects [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95253-6]. Online and Global. 24-30 October 2020. edited by M. Yablonina, A. Marcus, S. Doyle, M. del Campo, V. Ago, B. Slocum. 120-123
summary	Short Stack is a bare minimal structure using only laminated sheets of structural metal decking for all elements of its structure and enclosure. The project operates under a simple principle. Structural metal decking is a one-way system that resists loads well in one direction, but not in the other. When this decking is stacked into rotated sections and tensioned together, the resultant sandwich of corrugated metal is resistant to loading in every direction. These sandwiches become walls, floors, and roofs to a temporary structure. The compounded effect at the edges of the rotated and cropped decking is one of filigree or an ornamental articulation. The sandwich, which is mostly hollow due to the section of the decking, provides a sense of airy lightness that is at odds with its bulky mass. The structure, therefore, teeters between being unexpectedly open and at once heavy. The economy of the project is in its uniformity and persistent singularity. By maintaining a single palette of material and using a plasma cutting CNC bed to cut each section of the decking, the structure is simply assembled. The digital intelligence that lies underneath the apparent formal simplicity of the project is two-fold. Firstly, each sheet of metal decking is different from the next. Because of the locations of bolt-holes and constant variability of rotation and cropping of each sheet, it is a project that expresses uniformity rather than articulation through discretization. Secondly, the project appears solid and monolithic but is hollowed structurally to minimize the weight of the assembly. Parametric tools are implemented to maximize material efficiencies by hollowing the interior of each sandwich for load optimization. The project is presently in prototyping and documentation and will go into construction in Spring 2021 on a site in downtown Denver.

title	Extending the Passive Actuation of Low-tech Architectural Adaptive Systems by Integrating Hygroscopic and Thermal Properties of Wood
doi	https://doi.org/10.52842/conf.ecaade.2020.2.641
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 641-650
summary	Recent studies involving the passive actuation of zero-energy architectural adaptive systems using programmable materials have addressed the prototyping of wood motion responses by utilizing its latent hygroscopic properties. Most of these systems have focused on mechanisms that are triggered by varying levels of humidity, with very limited efforts addressing the effect of temperature variations; a challenge in hot climatic zones. This paper extends the passive actuation of adaptive systems in climates where humidity and/or temperature variations are dominant. A series of physical experiments were conducted to observe wood veneer sample deflection and motion response behavior under three varying temperature and humidity conditions, with constant values of fiber orientation, lamination, thickness, type of wood, and sample proportion and geometry. The experiment results showed that the coefficient of thermal expansion is an effective parameter, where higher deflection and response speed was recorded under high relative humidity (>80%) upon increase in temperature (>35°).

summary	The worldwide lockdowns during the first wave of the COVID-19 pandemic had an immense effect on the public space. The events brought up an opportunity to redesign mobility plans, streets, and sidewalks, making cities more resilient and adaptable. This paper builds on previous research of the authors that focused on the development of a graphene-based sensing material system applied to a smart pavement and utilized to obtain pedestrian spatiotemporal data. The necessary steps for gradual integration of the material system within the urban fabric are introduced as milestones toward predictive modeling and dynamic mobility reconfiguration. Based on the capacity of the smart pavement, the current research presents how data acquired through an agent-based pedestrian simulation is used to gain insight into mobility patterns. A range of maps representing pedestrian density, flow, and distancing are generated to visualize the simulated behavioral patterns. The methodology is used to identify areas with high density and, thus, high risk of transmitting airborne diseases. The insights gained are used to identify streets where additional space for pedestrians is needed to allow safe use of the public space. It is proposed that this is done by creating a dynamic mobility plan where temporal pedestrianization takes place at certain times of the day with minimal disruption of road traffic. Although this paper focuses mainly on the agent-based pedestrian simulation, the method can be used with real-time data acquired by the sensing material system for informed decision-making following otherwise-unpredictable pedestrian behavior. Finally, the simulated data is used within a predictive modeling framework to identify further steps for each agent; this is used as a proof-of-concept through which more insights can be gained with additional exploration.

title	Ambiguous vs. Concrete: Identifying the Effect of Design References with Various Level of Details on Designer's Creativity in the Early Design Phase
doi	https://doi.org/10.52842/conf.caadria.2020.2.587

summary	During the early design phase, spatial designers search for design references to develop design ideas. In this process, the level of detail (LoD) of design references can significantly influence the quality of design outcomes. However, previous studies have only suggested guidelines indicating that abstract references are useful in the early design phase without the degree of LoD. In response, this study aims to identify the impact of LoD of design references on design outcomes during the design concept development. To this end, we proposed three different reference types (abstract, hybrid, and concrete), and conducted experiments to assess the creativity and efficiency of the design outcome per LoD type. We also developed the FPRT (Floor Plan Retrieving Tool) system along with 7,842 existing residential floor plans for the experiments. The results of the study showed that there is a significant difference in design outcomes depending on the LoD types.

summary	Urban morphology significantly impacts resident's well-being. This study examines the impact of urban environments on the sense of well-being, using virtual reality as a research environment. Most of the world's population already live in urban localities; and it is expected that in two decades, more than 70% of the total population of the planet will be city dwellers(UN 2018). This study examines the impact of various urban configurations on dwellers well-being. Participants were presented with simulated pedestrian movement through 24 virtual urban environments. The environments differed by density level, spatial configurations, vegetation, and commerce. Participants assessed each alternative through structured questionnaires. It has been found that the density and presence of vegetation and commerce in the urban area have a significant impact on the subject's well-being in urban environments. extreme levels of densification have a negative effect on subjects' feelings, but vegetation and commerce, especially at the high levels of density, can improve them. In this research we established the framework for planning principles that can improve urban densification processes. An understanding of the wellbeing of urban dwellers, and the parameters that can influence this, will help urban designers and planners in creating better urbanized future environments.

summary	Urban morphology significantly impacts resident's wellbeing. This study examines the impact of urban environments on the sense of wellbeing, using virtual reality as a research tool. Participants were presented with simulated pedestrian movement through 24 virtual urban environments. The environments differed by density level, vegetation, and commercial activity. Participants assessed each alternative through structured questionnaires. The relationship between the participants' feelings and densification levels, vegetation, and commercial activity was analyzed. Densification levels independently predicted participant's wellbeing. An increase in density levels predicted a decrease in the participants' sense of belonging and wellbeing. At all levels of density, the presence of commercial activity predicted a higher sense of belonging.Density, vegetation and commercial activity had a significant impact on the participants' wellbeing. Extreme densification had a negative effect on the participants' feelings; but vegetation and commercial activity, especially at high-density levels, improved this feeling.

source	Architectural Intelligence Selected Papers from the 1st International Conference on Computational Design and Robotic Fabrication (CDRF 2026)
summary	This paper presents a novel building technique for the formwork of thin shell structures with 3d-printed bending-active mesh sheets. To enhance the structural stiffness of the flexible plastic materials, bending-active form is applied to utilize the geometry stiffening effect through the large deformation of bending. As it is the main problem to determine the final geometry of the bent surface, design methods with consideration of the numerical simulation is researched and both simulations via dynamic relaxation and finite element method are presented. Several demonstrator pavilions and the building process are shown to test the feasibilities of the presented building techniques in the real shell project. It is expected that this method could be applied into more thin shell projects to realize an efficient building technology with less exhaust of materials.

title	A Preliminary Study on the Formation of the General Layouts on the Northern Neighborhood Community Based on GauGAN Diversity Output Generator
doi	https://doi.org/https://doi.org/10.1007/978-981-33-4400-6_17
source	Proceedings of the 2020 DigitalFUTURES The 2nd International Conference on Computational Design and Robotic Fabrication (CDRF 2020)
summary	Recently, the mainstream gradually has become replacing neighborhood-style communities with high-density residences. The original pleasant scale and enclosed residential spaces have been broken, and the traditional neighborhood relations are going away. This research uses machine learning to train the model to generate a new plan, which is used in today’s residential design. First, in order to obtain a better generation effect, this study extracts the transcendental information of the neighborhood community in north of China, using roads, buildings etc. as morphological representations; GauGAN, compared to the pix2pix and pix2pixHD, used by predecessors, can achieve a clearer and a more diversified output and also fit irregular contours more realistically. ANN model trained by 167 general layout samples of a neighborhood community in north of China from 1950s to 1970s can generate various general layouts in different shapes and scales. The experiment proves that GauGAN is more suitable for general layout generation than pix2pix (pix2pixHD); Distributed training can improve the clarity of the generation and allow later vectorization to be more convenient.

source	Proceedings of the 2020 DigitalFUTURES The 2nd International Conference on Computational Design and Robotic Fabrication (CDRF 2020)
summary	GAN is an efficient generative model. By performing a latent walk in GAN, the generation result can be adjusted. However, the latent walk cannot start from a selected image. The embedGAN is proposed to embed selected images into GAN and remain the generation effect. It contains an embedded network and a generative network. Application cases of residential interior design are given in the article. With advantages of a low computing cost and short training time, embedGAN shows its potential. The embedGAN algorithm framework can be applied to various GANs.

summary	Generative design methods may involve a complex design space with an overwhelming number of alternatives with their form and design performance data. Existing research addresses this complexity by introducing various techniques for simplification through clustering and dimensionality reduction. In this study, we further analyze the relevant literature on design space simplification and exploration to identify their potentials and gaps. We find that the potentials include: alleviating the choice overload problem, opening up new venues for interrelating design forms and data, creating visual overviews of the design space and introducing ways of creating form-driven queries. Building on that, we present the first prototype of a design analytics dashboard that combines coordinated and interactive visualizations of design forms and performance data along with the result of simplifying the design space through hierarchical clustering.

summary	The Perceptions of Depth and Distance are considered as two of the most important factors in Virtual Reality Environments, as these environments inevitability impact the perception of the virtual content compared with the one of real world. Many studies on depth and distance perceptions in a virtual environment exist. Most of them were conducted using Head-Mounted Displays (HMDs) and less with large screen displays such as those of Cave Automatic Virtual Environments (CAVEs). In this paper, we make a comparison between the different aspects of perception in the architectural environment between CAVE systems and HMD. This paper clarifies the Virtual Object as an entity in a VE and also the pros and cons of using CAVEs and HMDs are explained. Eventually, just a first survey of the planned case study of the artificial port of the Trajan emperor near Fiumicino has been done as for COVID-19 an on-field experimentation could not have been performed.

summary	Deep learning is expected to offer new opportunities and a new paradigm for the field of architecture. One such opportunity is teaching neural networks to visually understand architectural elements from the built environment. However, the availability of large training datasets is one of the biggest limitations of neural networks. Also, the vast majority of training data for visual recognition tasks is annotated by humans. In order to resolve this bottleneck, we present a concept of a hybrid system—using both building information modeling (BIM) and hyperrealistic (photorealistic) rendering—to synthesize datasets for training a neural network for building object recognition in photos. For generating our training dataset, BIMrAI, we used an existing BIM model and a corresponding photorealistically rendered model of the same building. We created methods for using renderings to train a deep learning model, trained a generative adversarial network (GAN) model using these methods, and tested the output model on real-world photos. For the specific case study presented in this paper, our results show that a neural network trained with synthetic data (i.e., photorealistic renderings and BIM-based semantic labels) can be used to identify building objects from photos without using photos in the training data. Future work can enhance the presented methods using available BIM models and renderings for more generalized mapping and description of photographed built environments.
