title	Measuring Human Perception of Biophilically-Driven Design with Facial Micro-expressions Analysis and EEG Biosensor
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_22
summary	This paper investigates the role technology and neuroscience play in aiding the design process and making meaningful connections between people and nature. Using two workshops as a vehicle, the team introduced advanced technologies and Quantified Self practices that allowed people to use neural data and pattern recognition as feedback for the design process. The objective is to find clues to natural elements of human perception that can inform the design to meet goals for well-being. A pattern network of geometric shapes that achieve a higher level of monitored meditation levels and point toward a positive emotional valence is proposed. By referencing biological forms found in nature, the workshops utilized an algorithmic process that explored how nature can influence architecture. To measure the impact, the team used FaceOSC for capture and an Artificial Neural Network for micro-expression recognition, and a MindWave sensor manufactured by NeuroSky, which documented the human response further. The methodology allowed us to establish a boundary logic, ranking geometric shapes that suggested positive emotions and a higher level of monitored meditation levels. The results pointed us to a deeper level of understanding relative to geometric shapes in design. They indicate a new way to predict how well-being factors can clarify and rationalize a more intuitive design process inspired by nature.

title	Consistency Checker - An automatic constraint-based evaluator for housing spatial configurations
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 351-358

summary	The gradual rise of artificial intelligence (AI) and its increasing visibility among many research disciplines affected Computer-Aided Architectural Design (CAAD). Architectural deep learning (DL) approaches are being developed and published on a regular basis, such as retrieval (Sharma et al. 2017) or design style manipulation (Newton 2019; Silvestre et al. 2016). However, there seems to be no method to evaluate highly constrained spatial configurations for specific architectural domains (such as housing or office buildings) based on basic architectural principles and everyday practices. This paper introduces an automatic constraint-based consistency checker to evaluate the coherency of semantic spatial configurations of housing construction using a small set of design principles to evaluate our DL approaches. The consistency checker informs about the overall performance of a spatial configuration followed by whether it is open/closed and the constraints it didn't satisfy. This paper deals with the relation of spaces processed as mathematically formalized graphs contrary to existing model checking software like Solibri.

title	Ceramic AM Gantry Structures - Discretisation and connections between beams and columns
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 483-492

summary	The manufacture of architectural components driven by digital design tools and Additive Manufacturing (AM) allows the achievement of highly evolved constructive systems, more integrated into a specific reality to which it is intended to respond, resulting in unique and adapted solutions with high geometric and material performances. Considering the application of these methods to common structural elements, namely beams and columns, for which there are already several examples demonstrating their feasibility, we find that it is necessary to provide a sound answer to an element that is fundamental for these proposals to function together as a single system - the moment of connection between beams and columns. In this sense, this paper proposes the design and test of a set of connections with adapted geometry between beams and columns, produced through ceramic Liquid Deposition Modelling (LDM), applying logics of topological optimization. This work foresees the development of a constructive system that incorporates reversible and irreversible connections, being formalised in a set of gantry structures formed by two vertical elements and a horizontal one, giving the comparative model between digital design and manufacture methods and the traditional ones.

title	Augmented Spaces - If walls could talk
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 575-584
doi	https://doi.org/10.52842/conf.ecaade.2021.2.575
summary	This paper explores the development of Augmented Spaces that involve embedding within the built environment, digitally responsive recognition of human presence. Contemporary digital media provides the opportunity to enhance physical space with the property of immediate interaction, which results in a high level of user engagement and responsivenenss. Through the addition of digital media, emotional and reflective value can be added to the built form. If space is designed to be reactive, rather than passive, a dialogue can be established between the user/inhabitant and the environment. We report on the establishment and analysis of a set of prototype digital interventions in urban space that react to human presence. One is in a building threshold space; one an urban street. We describe the development of a digital particle system with two inputs; the first being the geometry that generates the particles and the second being the geometry that displaces the particles. The research goals that we report on are driven by three over-riding response criteria, Visceral, Behavioural and Reflective.

title	Inductive Creative Processes within Ideation Phases of Digital Design Products
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 463–473
summary	This article aims to identify and analyze inductive aspects (those which go from particular instances to the general configuration) present in ideation phases of digital design projects (such as apps, websites and tools for companies’ internal communications), with special emphasis on how induction occurs in creative processes. Using a qualitative methodological approach, the analysis is based on in-depth, semi-structured interviews with digital designers, on a literature review on the subjects of creativity and classic design method, as well as on a design documentary. Research findings suggest the importance of combining the use of verbal and visual communication resources in group dynamics; the need for designers to be highly proficient in the tools and techniques used while generating new alternatives, regardless of their physical/analogical or virtual/digital nature; and to allocate, whenever possible, ample time to explore ideas in order to push the limits of each project being developed.

title	Future Coastal Cities with Biorock Infrastructure - Alternative Coastal Futures with Biodesign
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 483-492
doi	https://doi.org/10.52842/conf.caadria.2021.1.483
summary	Despite having the potential of being a durable building material, Biorock, a form of calcium carbonate formed by the electro-accumulation of minerals dissolved in seawater, has never been applied on an architectural level due to its slow accretion process. This paper aims to plays out the possible narrative of this slow accruing material process in the incrementally submerged coastline of Jakarta, to empower local marginalized communities to self-construct a new city for habitation using Biorock, especially where building material resources may be limited. Urban cores with basic communal, housing and aquaculture facilities will be established using Biorock as the main building structure, which would be harvested in response to the gradual sea level rise.

title	Multimodal Virtual Experience for Design Schools in the Immersive Web

doi	https://doi.org/10.52842/conf.ecaade.2021.1.415
summary	The COVID-19 pandemic has made most schools, universities, and gathering spaces fully virtual. Commonly used communication platforms such as Zoom, Skype, and Microsoft Teams are limited in recreating physical interactions and offer mostly static interfaces with limited occasions for spontaneous encounters. This project creates a space that seeks to address this issue, first through the digitization of familiar physical spaces, and then through their augmentation via WebXR technologies[1]. A gamification strategy is adopted, where users can virtually learn, collaborate and socialize through personalized avatars within a dynamic and multi-sensorial digital environment. In this paper, we present a completed prototype that is currently being tested at the Harvard Graduate School of Design. The school of architecture has been digitized and experientially augmented thanks to an asymmetrical system that offers rich modalities of interaction through different platforms. The project builds upon the wide experiential potential of digital platforms, otherwise not possible in reality, and implements a customized multi-modal user interface (Reeves et al. 2004).

title	A Human-Centred Framework for Sonic Mapping: Developing Representation Methods to Analyze Sonic Environments
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 592-601
summary	This paper contributes to a new way of bringing the human physically into the in-situ environment and utilizing mapping methods of the actual sonic experience, which current acoustic studies and other environmental studies are lacking in their reliance on graphical representations. An entire era has been dominated by a visual communication of the sonic environment, yet sonic studies are not primarily dependant on visual experience. The paper reviews the possibilities of current methods of representation of the sonic experience. Representation, being crucial in the layperson’s perceptive awareness of key features of the environment can benefit from increased levels of listening methods. This includes mapping the qualities of information that reveal the environment.

title	Limits to Applied ML in Planning and Architecture - Understanding and defining extents and capabilities
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 243-252
doi	https://doi.org/10.52842/conf.ecaade.2021.1.243
summary	There has been an exponential increase in Machine Learning (ML) research in design. Specifically, with Deep Learning becoming more accessible, frameworks like Generative Adversarial Networks (GANs), which are able to synthesise novel images are being used in the classification and generation of designs in architecture. While much of these explorations successfully demonstrate the 'magic' and potential of these techniques, their limits remain unclear, with only a few, but crucial, discussions on underlying fundamental limits and sensitivities of ML. This is a gap in our understanding of these tools especially within the complex context of planning and architecture. This paper seeks to discuss what limits ML in design as it exists today, by examining the state-of-the-art and mechanics of ML models relevant to design tasks. Aiming to help researchers to focus on productive uses of ML and avoid areas of over-promise.

summary	The circumstances of the pandemic have resulted in the closure of workshops and Fab Labs and put physical making on hold for fabrication-based design courses. However, with digital fabrication having become a crucial component of design education, involving the critical transition from design ideas represented digitally to being realized physically, alternative approaches needed to be found. Remote making can be enabled by the potentials of small-scale modular machines, which due to their low cost, are easily distributable and can be shipped to each student in a design studio. The use of at-home fabrication offers new possibilities for project-adaptive prototyping tools. Desktop scaled fabrication tools designed to reach a distributed audience abound in industry, academia, and amongst DIY-ers. Drawing from these precedents, a desktop milling machine called the TinyZ was developed to support digital fabrication in an architectural studio held at MIT in the Spring of 2021. The machine was designed to be an easily reconfigurable rapid prototyping tool intended to adapt to evolving design processes. The TinyZ Kit introduced students to the basics of machine building, electronics, and computer numerically controlled (CNC) programming. The outcome of the studio showed the potential for different home labs to develop specializations and to collaborate by out-sourcing, offering a way for students to work together remotely. Finally, the work of the studio demonstrated that new material processes developed remotely could return to fab labs and extend the capacities of shared maker spaces.

summary	Human imagination has played with the idea of an alternative technological world for years. From dystopian proposals like Neuromancer or The Matrix to more positive views like the recent Upload series, the exploration of the friction between the digital world and the physical world has entertained the imagination of our society for decades. Outside the fictional environments, the omnipresence of the internet and the development of “the cloud” are showing that the virtual world is possible and that the idea of a Metaverse is no longer part of science fiction but a very real future for human relations (Winters 2021). In line with the idea of the Metaverse, the intersection of the virtual and the physical world is being explored through the idea of Extended Realities. Technology is allowing humans to enhance their capabilities more than ever, and in fact, it has been proposed that we are entering the Augmented era (King 2014). This paper explores the opportunities and possible challenges that “Extended Architecture” has by analyzing a research project based on augmented reality as the media to explore these ideas. This project will propose a speculative approach to how the fact that in the recent future, everyone will have access to an AR device will change the way we perceive and understand our architectural environment.

title	Reusable Augmented Concrete Casting System - Accessible method for formwork manufacturing through holographic guidance
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 371–380
doi	https://doi.org/10.52842/conf.ecaade.2022.1.371
summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

summary	This paper provides an original empirical study examining the engagement of artists, curators and virtual tools. The case focusses on a collaborative project called In the Forest with the Trees we Made. Since the publishing of the project, many compelling findings have been made in reference to both CAAD design and contemporary curatorial and creative practices. They have been made possible, by allowing multi-participants, institutions and disciplines to project their specific creative acts into a single sharable portal. The paper describes the activities of the participants. It then offers a discussion of how these interactions are seated in the new digital realm. The skills of spatialisation, movement through space, generation of geometry and orientation are made accessible through this new digital tool. To conclude, a reflection on the changes in space perception and how space becomes the matter being exhibited is offered.

title	Augmented Accuracy - A human-machine integrated adaptive fabrication workflow for bamboo construction utilizing computer vision
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 345-354
doi	https://doi.org/10.52842/conf.ecaade.2021.1.345
summary	Despite being sustainable, strong and lightweight, naturally grown bamboo poles are currently used in restricted building typologies. This is due to the large tolerances in the built structures, which is caused by the variations in the dimensions and geometry of natural material as well as the manual, uninformed and imprecise assembly methods. In previous work, we introduced an adaptive fabrication method for bamboo structures that can monitor the fabrication process and compensate for deviations between built and designed form. As a proof of concept, the method is suitable for small scale bamboo structures in 2D- or simple 3D configuration. This paper extends the previous method by integrating the adaptation strategies into a cohesive fabrication and assembly workflow for large scale complex bamboo structures. To enable that, a more effective sensor localization method, adaptation algorithm, connection and assembly system, as well as web-based user interface are developed. The effectiveness of the proposed methods is demonstrated through the fabrication of a pavilion scale branching bamboo structure that complies with intended geometric boundary conditions. Even though the material has substantial geometrical variations, the final structure shows small geometric deviations and a successful interface with the prefabricated roof elements. Our work shows how vernacular materials and processes can be digitally augmented in order to reliably produce building structures, hence enabling their usage in modern applications to a larger extent.

doi	https://doi.org/10.52842/conf.ecaade.2021.2.059
summary	Due to the more significant architectural complexity, it is helpful to include structural analysis studies in the early design stages. An architectural team typically carries out the structural grid fit in this phase. This limitation may lead to the structural distribution in the initial phase not being the most appropriate. This work aims to provide a tool for architects oriented design by optimising the cost of the structure, making an initial layout for residential buildings with the regular shape of steel structures using the generative design, which allows the creation of structural BIM models that comply with the requirements of stability and resistance for gravity design specified in the American code ASCE 360 as starting point on the conceptual design. The paper describes the computational design development for the structural building grid using multi-criteria optimisation solved by a genetic algorithm.

summary	This study contains new results concerning several aspects of reciprocal frame research. The paper intends to induce portability and deployability in reciprocal structures using straight bars. A complex grillage, when created as an assembly of units, which is a self-standing 3d structure is Reciprocal Frames(RF) Structure. While these structures are attractive reflecting their simplicity, beauty, and ease of assembly, disassembly, deployment, and reuse of elements; creating such structures, however, is difficult. Straight bars encourage its use in building the RF structures which further led to the study of the Deployable Reciprocal Frame Structure. An attempt is made to design a structure that has the potential of being converted into a Deployable Emergency Module that offers protection after natural disasters.

summary	CAAD research has frequently investigated the realm of public participation in large scale urban design re-development. Yet, the recurring problem lies with the lay-person often not being able to read 2d and 3d graphic information effectively, and hence be able to participate in the process of design development proactively. To date, much-existing research focuses on developing designs for urban settings using contemporary interaction devices such as the /Hololens/; such devices, with custom interfaces, require a significant level of expertise, or an experienced guide, to help navigate or create within these environments. Our paper presents a novel alternative based on real-time-virtual-engines, XR, and a parametric back-end system. The paper discusses the advantages that the resulting tangible user interface (TUI) can play in the lay-persons engagement in the design process. In the paper, we describe how the integration of interaction design (IxD) and augmented reality (AR) offer new opportunities due to the increasing availability of barrier-free technologies that can better include lay-persons as active participants in the design development process.

title	[AR]OBOT: the AR-Assisted Robotic Fabrication System for Parametric Architectural Structures

summary	[AR]OBOT tries to assist the robotic fabrication process for parametric architectural structures with Augmented Reality (AR) technology to explore new possibilities for easy architectural robotic operations. Due to the lack of computer programming skills and the disconnection between design and fabrication, architects are hampered in the robotic operation process. As part of our project, we create a visualization prototype in which robotic and on-site related information is being shown through AR devices overlapping on the physical world; followed by a robotic trajectory planning method in which designers’ gestures are being identified by AR as location nodes and calculated with the obstacle avoidance system; and an operation process in which robots are being controlled by human gestures and interactions with holographic simulation to enhance the robotic fabrication process efficiency and safety. In this paper, we share the preliminary results to demonstrate a new kind of AR-assisted workflow for the architects to perform the robotic fabrication of parametric architectural structures intuitively.

summary	This research project, entitled AR Digi-Component, tries to digitalize the traditional architectural components and combines Augmented Reality (AR) technologies to explore new possibilities for architectural design and assembly. AR technology and Digitalize components will help to achieve a real-time immersive design and an AR-assisted robotic fabrication process through the augmented environments. As part of the AR Digi-Component project, we created an experimental design prototype in which designers gestures are being identified in AR real-time immersive design process, and a fabrication prototype in which traditional 2D drawings are being replaced by 3D on-site holographic guidance, followed by an assembly process in which robotic operations are being controlled by humans within an AR simulation to enhance the assembly efficiency and safety. In this paper, we are sharing the preliminary research results of such AR-assisted tests, for which we used a UR10 Robotic arm in combination with Microsoft HoloLens as well as in terms of software Rhino, HAL Robotics, FURobot, PX Simulate, and Fologram plugin in Grasshopper, to demonstrate new kind of applications and workflow of AR technology for real-time, immersive design and robotic fabrication.

title	Design of Self-Organized Structural, Based on the Phenomenon of Crystalline Particle Aggregation

summary	This article deals with the design of structures with the quality of self-organization, applying emergency phenomena in particle aggregation, where a transformation of energy takes place towards structures and states of great complexity from rules of low level of sophistication, when there is an exchange of matter and energy with the outside, and are far from equilibrium. This I+D+i design project focuses on the scientific method, which means observing the phenomenon to answer: What training principles attributable to self-organization underlie the studied phenomenon? and, thus, being able to hypothesize or simulate a model from a Grasshopper environment fed with oversampling methods through Machine Learnig techniques, which allows us to question: How to apply the principles of formation resulting from the emergency phenomenon studied, to the design of self-organized structures? The results conclude that the quality of self-organization of these emerging structural systems is directly proportional to the similarity between their parts, their nesting capacity, the energy levels with which they interact, and their environment, which allows progress in research at scales and open up new future design and manufacturing possibilities.
