title	Smart assembly in digital fabrication: designing workflow
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 755-764

summary	Digital fabrication project in academia has produced many grounds for experimentation. In recent years, techniques have also been tested extensively in practice within commercial project setting. This gives rise to an emerging breed of architectural practices whose work is increasingly centred on resolution of complex geometry to re- alizable projects. The resolution of parametrically driven design to production projects requires a different workflow, as often the com- pressed timeframe and budget requires the parametric model to cope with multiple streams of construction output as well as utilize the model in concurrent design processes. This paper examines a com- mercial project as case study to explore the abstraction, reduction and dissemination of information within a digital fabrication workflow. In this project, digital fabrication is deployed to reduce risk; mainly in manufacturing and its lead time. The research reveals how metadesign process at an early stage of the project can contribute to increase effi- ciency of the parametric model as well as delivering multiple streams of information for all the collaborators: architects, fabricators and builders. The team designed the assembly procedure into the paramet- ric workflow to facilitate off-site and on-site assembly. This is possi- ble through imbedding ‘smart’ detailing and structuring information with the workflow. The paper concludes by reflecting on the work- flow and asks if a metadesign driven fabrication workflow can create a more holistic approach to digital fabrication. The outcome of the case study is just one instance of the parametric machine that is devel- oped from an understanding of assembly process. This paper responds to the theme of continuous designing, through looking at digital fabri- cation as co-emergence of design procedure and practice.

title	Workmanship of Risk: continuous designing in digital fabrication
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 651-660

summary	Research projects exploring the realm of digital fabrication have shifted in recent years from developing novel techniques and outcomes to the development of tools that are part of the design pro- cess. The alignment of material systems with digital fabrication tech- nology and tooling processes have led to new terminology such as ‘digital craft’ and ‘digital making’; both terms imply a relationship be- tween craft and digital design and fabrication. Also implied is an inti- mate relationship between material production, digital tools and CNC fabrication techniques; critical ingredients in contemporary design processes. David Pye’s concept of ‘the workmanship of risk’ is used extensively in current discourse as a means to qualify digital fabrica- tion as craft production. This reading of digital fabrication as craft is limited because the word craft is used as an analogy to draw parallels between craft production and digital fabrication. There is a gap in the knowledge of what contemporary craft practice can bring to digital fabrication as a discourse or more precisely, the mechanism that al- lows digital fabrication projects to be read as a form of craft practice. This paper suggests that craft practice is rooted in the relationship be- tween material, tools and technique as an intricate workflow within a project; quantifying risk is just a means to assess this relationship. The workflow however can be considered as autopoietic in nature; it is both self-referential and self-making at the same time as continuously designing.

summary	This paper presents research into the development of a novel self-supporting, lightweight, and transparent polymer 3D-façade component for the integration of organic photovoltaic (OPV) modules into building facades. To explore the integration of organic photovoltaic modules into novel plastic sandwich material systems, using parametric design tools as well as solar and structural simulations were used. Physical prototypes and experiments informed and validated a digital tool chain. In the following sections, we use this research as a case study to reflect on the accessibility and interoperability of low-level visual programming tools and specialized FEM programs. Lastly, lessons learned and pitfalls are discussed and shared.

summary	This paper introduces a series of design and fabrication tests directed towards the use of bendable 3D printing materials in order to simplify a foam bubble-based geometry as a frame structure for modular assembly. The aspiration to reference a spittlebug's bubble cocoon in nature for a light installation in the urban context was integrated into a computational workflow conditioning light-weight, material-, and cost savings along with assembly-simplicity. Firstly, before elaborating on the project motivation and background in foam structures and applications of 3D-printed thermoplastic polyurethane (TPU) material, this paper describes the physical nature of bubble foams in its relevant aspects. Subsequently this is implemented into the parametric design process for an optimized foam structure with Grasshopper clarifying the need for flexible materials to enhance modular feasibility. Following, the additive manufacturing iterations of the digitally designed node components with TPU are presented and evaluated. Finally, after the test assembly of both components is depicted, this paper assesses the divergence between natural foams and the case study structure with respect to self-organizing behavior.

summary	Patten and Ishii (2000) discovered that people are employing more versatile strategies for spatial distribution when using a tangible user interface (TUI) as opposed to a graphics user interface (GUI) (Patten & Ishii, 2000). Besides, the generated information outputs of conventional two-dimensional interacting screens are currently almost entirely addressing the visual and acoustic senses but lacking in other sensory stimuli - such as haptic, body equilibrium and sense of gravity. With the experiment described here, the multi-dimensionality of both the input on the interface and the output of the human interaction will be challenged. This paper aims to introduce a method to a real world versatile three-dimensional interface actuating a simulated spatial environment that substantiates the more unconventional sensory perception mentioned above. A physical prototype using an Arduino will be assembled to test the feasibility of the structure.

title	Timber De-Standardized 2.0 : Mixed Reality Visualizations and User Interface for Processing Irregular Timber
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 121-130

summary	Timber De-Standardized 2.0†is a mixed reality (MR) user interface (UI) that utilizes timber waste produced by manufacturing dimensional lumber, suggesting an expanded notion for "material usability‚ in timber construction. The expanded notion of designing with discarded logs not only requires new tools and technologies for cataloguing, structuring, and fabricating. It also relies on new methods and platforms for the visualization and design of these structures. As a†MR†UI,†Timber De-Standardized†enables professionals and non-professionals alike to seamlessly design with irregular logs and to create viable structural systems using an intuitive†MR†environment. In order to develop a†MR†environment with this level of competency, the research aims to finesse the visualization techniques in the immersive full-scale†3D†environment and to minimize the use of alternative 2D UI(s). The research methodology†focuses on†(1) cataloguing and extracting basic properties of various tree logs, (2)†refining mesh visualization for better user interaction, and†(3)†developing†the†MR†UI to increase user design agency with custom menu lists and operations.†This methodology will extend the usability of†MR†UI protocols to a broader audience while democratizing design and enabling the user as co-creator.

summary	HoloWall is a wall assembly that integrates mixed reality (MR) protocols with nonuniformly sized lumber to develop a customized hollow-core cross-laminated timber (HCCLT). The performance-driven design workflow leverages the MR technology and tiling automation of nonuniform wood boards to guide material processing and fabrication of a customized HCCLT prototype. This paper proposes to expand the usage and the viability of customized HCCLT as a structural component. Upcycling locally salvaged wood elements, the prototype develops a material language of lamination that peels away in calibrated gradients to generate structural and visual porosity. By engaging with the computational environment and the physical making process through the MR workflow, users are able to explore an accessible design streamline.

summary	Timber De-Standardized is a framework that salvages irregular and regular shaped tree logs by utilizing a mixed reality (MR) interface for the design, fabrication, and assembly of a structurally viable tree log assembly. The process engages users through a direct, hands-on design approach to iteratively modify and design irregular geometry at full scale within an immersive MR environment without altering the original material. A digital archive of 3D scanned logs are the building elements from which users, designing in the MR environment, can digitally harvest (though slicing) and place the elements into a digitally constructed whole. The constructed whole is structurally analyzed and optimized through recursive feedback loops to preserve the user’s predetermined design. This iterative toggling between the physical and virtual emancipates the use of irregular tree log structures while informing and prioritizing the user’s design intent. To test this approach, a scaled prototype was developed and fabricated in MR. By creating a framework that links a holographic digital design to a physical catalog of material, the interactive workflow provides greater design agency to users as co-creators in processing material parts. This participation enables users to have a direct impact on the design of discretized tree logs that would otherwise have been discarded in standardized manufacturing. This paper presents an approach in which complex tree log structures can be made without the use of robotic fabrication tools. This workflow opens new opportunities for design in which users can freely configure structures with non-standardized elements within an intuitive MR environment.

title	Ashen Cabin
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. 176-181
summary	Ashen Cabin, designed by HANNAH, is a small building 3D-printed from concrete and clothed in a robotically fabricated envelope made of irregular ash wood logs. From the ground up, digital design and fabrication technologies are intrinsic to the making of this architectural prototype, facilitating fundamentally new material methods, tectonic articulations, forms of construction, and architectural design languages. Ashen Cabin challenges preconceived notions about material standards in wood. The cabin utilizes wood infested by the Emerald Ash Borer (EAB) for its envelope, which, unfortunately, is widely considered as ‘waste’. At present, the invasive EAB threatens to eradicate most of the 8.7 billion ash trees in North America (USDA, 2019). Due to their challenging geometries, most infested ash trees cannot be processed by regular sawmills and are therefore regarded as unsuitable for construction. Infested and dying ash trees form an enormous and untapped material resource for sustainable wood construction. By implementing high precision 3D scanning and robotic fabrication, the project upcycles Emerald-Ash-Borer-infested ‘waste wood’ into an abundantly available, affordable, and morbidly sustainable building material for the Anthropocene. Using a KUKA KR200/2 with a custom 5hp band saw end effector at the Cornell Robotic Construction Laboratory (RCL), the research team can saw irregular tree logs into naturally curved boards of various and varying thicknesses. The boards are arrayed into interlocking SIP façade panels, and by adjusting the thickness of the bandsaw cut, the robotically carved timber boards can be assembled as complex single curvature surfaces or double-curvature surfaces. The undulating wooden surfaces accentuate the building’s program and yet remain reminiscent of the natural log geometry which they are derived from. The curvature of the wood is strategically deployed to highlight moments of architectural importance such as windows, entrances, roofs, canopies, or provide additional programmatic opportunities such as integrated shelving, desk space, or storage.

summary	The parameterisation of Andean ancestral graphic codes for 3D printing in geo-polymers and the development of the PAT (Translucent Artificial Poetics) project focuses on the ontological-political extension of the Sumak Kawsay or Buen Vivir/Vivir Bien (5 principles) concept in the context of the Global South and the epistemologies of the South. From this perspective, PAT presents a project architecture based on a transitional design methodology that operates from a transdisciplinary perspective. It seeks to integrate Andean ancestral knowledge (the vernacular) and new technologies, together with diverse strategies of collaborative, participatory design and new pedagogies that involve the new generations in the whole process of the first stage. This opens up opportunities for active social transformation through the construction of modules adapted to the needs of the inhabitants of the Andes.

title	Use of Cadastral Data for the Development of Spatial Decision Support Systemsfor Coping with the Consequences of Natural Disasters
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	This paper investigates the potential usefulness of cadastral data to form the core part of databases of Spatial Decision Support Systems [SDSS] that are capable to support decision-makers in dealing with emergency situations, such as earthquakes, floods and fires. Particular emphasis is given on how those data can be used to generate information that is necessary to planners and decision-makers when they cope with natural disasters at every stage of the development of the disaster: before the occurrence (planning and preventive measures), immediately after occurrence (short term measures), and well-after occurrence (medium and long term measures). This investigation is conducted using the Municipality of Magoula, Attica, Greece, as a case study area. This municipality is situated in the greater Athens area and was struck by the earthquake that occurred there in September 1999. Within the scope of the project, wehave used cadastral data about the study area and data recorded by the inspection teams in order to set-up a prototype SDSS database that could facilitate planning and decision-making in such a situation. Then, we have used that prototype to generate scenarios and information about typical tasks that are performed during emergency situations. The advantages that are realized from the integration of such data and information technologies are described and assessed, particularly, in comparison with the traditional approaches that are used in such situations.

title	Blockchain Grammars for Validating the Design Process
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 406-411
summary	This paper presents and develops the concept of Decentralised Autonomous Organisation (DAO) as a platform for collaboration, via a design scenario in which Blockchain (BC) technology is implemented for validation purposes. The envisioned scenario simulates designers proposing multiple solutions for a given task and adopting shape grammars and environmental analysis and regulations as design drivers. Proposed solutions are uploaded, stored, presented, and evaluated in a DAO in which the decision process gets validated via the reputation of the participants and its governance system. This study lays the foundation and ignites the development of a larger framework in which design collaboration and competition are fostered and results secured, impacting design value and financial transactions.

source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 573–582
doi	https://doi.org/10.52842/conf.caadria.2023.2.573
summary	Urban agricultural systems will be configured over the following years to respond to increasing climate change, urbanisation, and population growth. Controlled environment agriculture (CEA) is an increasing trend since it can be easily integrated into the built environment. However, this food production system requires intensive capital and energy resources, with artificial lighting as the primary contributor to its high operational impacts. New methods and tools for planning and design can provide innovative solutions for shifting urban agriculture toward sustainability. This paper addresses the food security challenge in cities by introducing a sunlight-based computational approach for indicating the agricultural possibilities of three-dimensional urban surfaces according to crop-centric environmental suitability. The procedure aims to improve CEA efficiency through a passive natural lighting optimisation strategy, indicating the sunlight thresholds for various crop species. The methodology interconnects solar radiation values measured through sunlight simulations with crops’ daily light integrals, using Singapore and Chennai (India) as case studies. The results suggest that urban areas with high solar radiation levels possess large degrees of year-round harvesting potential. This methodology can assist designers (architects, urban planners, and engineers) and local governments in strategizing urban agriculture developments and provide decision-making support for crop harvesting initiatives in cities.

The method alters only bump maps and leaves mesh geometry unchanged; it is suited to real - time applications where the primary concern is computational efficiency. The paper provides a representative model for deformable objects. Texture mapping and computer graphics techniques based on lighting are referenced as well. Finally, results are provided, along with the most noteworthy findings obtained with the use of this method.

title	Quill A Gesture Design Tool for Pen-based User Interfaces
source	U.C. Berkeley
summary	This dissertation describes the motivation, design, and development of a tool for designing gestures for pen-based user interfaces. Pens and other styli have been ubiquitous for recording information for centuries. Recently, pen-based computers have recently become common, especially small devices such as the Palm Pilot. One benefit pens provide in computer interfaces is the ability to draw gestures—marks that invoke commands. Gestures can be intuitive and faster than other methods of invoking commands. However, our research shows that gestures are sometimes misrecognized and hard to remember. We believe these problems are due in part to the difficulty of designing “good” gestures—that is, gestures that are easy to remember and are recognized well—and the lack of tools for helping designers create good gestures. We believe that an improved gesture design tool can help interface designers create good gestures for their applications. Since people confuse similar objects and misremember them, we performed experiments to measure why people perceived gestures as similar. We derived computational metrics for predicting human perception of gesture similarity. Based on the results of our experiments, we developed a gesture design tool, quill. The tool warns designers about gestures that may be hard to remember or recognize, and provides advice about how to improve the gestures. It also provides a convenient way to test recognition of gestures. To evaluate quill, a user study was performed with 10 professional user interface designers and one professional web designer. All designers were able to create gesture sets using quill, but not all designers benefited from quill’s suggestions. More work is needed to make suggestions useful for most designers. The primary contributions of this work are: • Improved understanding of the gesture design process, including the types of problems people encounter when designing gestures. • Computational models for predicting human-perceived gesture similarity. • Confirmation of the importance of good naming for gesture memorability. • An intelligent gesture design tool, quill, which automatically warns designers about potential problems with their gestures and advises them about how to fix these problems. This work also suggests several areas for future work in the areas of gesture design tools and gesture similarity and memorability.

summary	Gravity prescribes a very specific maxim for the built environment represented by the horizontal layer cake we are all so familiar with. This is contrasted by designs such as the International Space Station where no floor is present and every surface provides some function whether storage, data display and instrumentation or biological support infrastructure. Because of the homogeneity of approach to each surface an astronaut requires literal markers to orient oneself within the vessel. Very seldom within the natural, earth-bound environment does one find oneself in a situation where “up” is a questionable vector. What happens when architecture is translated to the virtual. What is the role of the architect or of his or her architecture in a virtual universe. Would a virtual architecture itself not become a social engine, its social context being that of online gaming, crowdfunding and social media? This engine's main role being the creation of architecturally inspiring gathering spaces for learning, playing and community building.

Actual difficulties depend, on one hand, on the fact D.B.M.S. that have been developed on other environments than CAAD, and on the other hand, on the fact that architectural design process is scarcely formalized. At the Department of T.E.C.A., at the University of Rome, a PhD research program is aimed to overcome difficulties, working out techniques of information management based on Knowledge Engineering and particularly on Knowledge Base Management Systems and Expert Database Systems. At present a prototype system is being developed, that can manage existing technical information, connected with buiIding process.

summary	Climate change has been increasing the vulnerability of cities to extreme weather events, especially those related to environmental dynamics already observed in each area. Considering that South America is one of the subcontinents that suffer the most from flooding, it is important to analyze how its cities have been preparing to face such extreme conditions. This paper aims to investigate the strategies indicated in climate action plans for mitigation and adaptation to flooding through the application of a parametric tool. To achieve this end, the methodology comprises five steps – from data collection to digital simulation. The results attained demonstrate that the strategies indicated in the plans are still very generic and incipient, so that the application of parametric methodologies of analysis and simulation can contribute to the searching for more effective and relevant actions.
