title The Computer's Role in Sketch Design: A Transparent Sketching Medium
source Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 227-244
summary Starting from an analysis of the current unsuitability of computers for sketching, three key requirements are identified, in particular the notion that re-drawing or over-drawing are more important than editing and tweaking. These requirements are encapsulated in the broad concept of Transparency, understood both literally and metaphorically. Two experiments in implementing aspects of Transparency are described. One subverts the Macintosh window manager to provide windows with variable transparency, so that tracing between applications becomes a practical possibility. The other implements a graphical interface that requires no on-screen palettes or sliders to control it, allowing uninterrupted concentration on the design in hand. User tests show that the tool can be learnt quickly, is engaging to use, and most importantly, has character.

summary A model of human-machine design interaction is presented. The model is based on synchrony of actions as it relates to designing, presenting, and discussing a design object over an electronic medium. The model descriptively accommodates existing technologies and areas of CAD research. The model prescriptively illuminates future CAD vis. the Web. The model is based on 3 factors : synchrony, presence, activity; and 2 players : human and machine. Future technologies are considered in terms of the a shifting role of the machine (the computer and the net) from server to agent to actor.

summary Contemporary voxel based CAD software uses a predetermined voxel space as a property placeholder for establishing relationships between boundaries and properties (weights). The Marching Shape algorithm, developed as an extension of the Ice Ray Shape Grammar, demonstrate how similar relationships between weights and boundaries can be developed without the fixed structure of Voxels. An extended Ice-Ray is presented that includes rules and schemas for polygons of more than 5 vertices, rules for the manipulation of weights as well as rules that establish relationships between them.

title Shell Structure of Bamboo Composite
source Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 445–454
summary This research is aimed at proposing a lightweight shell structure made from a bamboo composite. The research explores the addition of glass fiber to bamboo veneer for adhesion to produce a bamboo composite. Adding glass fiber improves the material’s elasticity and ductility and strengthens the bond between units of laminated bamboo veneer. Moreover, we utilized a simulation tool to analyze the structural performance and compare the shell structure’s mechanical differences before and after adding the glass fiber. In terms of fabrication, this paper presents a computational workflow for mesh segmentation and unrolling as well as a design for unique snap- fit joints for the connection between mesh strips. Finally, this paper outlines the fabrication of one part of the overall form as a demonstration case to verify the proposed method.

summary The modeling of the envelope and space frame for the new Mexico City Airport was a massive computational task, demanding the development of numerous new methods, tools and processes to deal with its complexity and scale. The shape of the envelope was created through form finding, leading to an all-encompassing lightweight shell with internal spans reaching 130 m. This paper will discuss the challenges faced and the methods used to develop a visually continuous and smooth space-frame model and envelope, while simultaneously complying with very strict spatial and programmatic constraints and structural optimisation criteria. It will further explain how dynamic relaxation was complemented with bespoke mechanisms for mesh manipulation, interfacing and mesh smoothing to fine-tune the final form.

summary The project investigates the potential of programmable bending - a strategy, which informs bending simulations of multilayered veneer elements with the data of its anisotropic grain structure. Project further examines the possibilities of using these irregular material characteristics as a design driver. The project questions the possibility of informing the design with the particular characteristics of the material structure and of creating complex geometries from non-customized or minimally customizes mass-produced elements. Project develops a workflow, in which a two-dimensional scan of the material is transformed into a vector field and consequently into a mesh with variable stiffness characteristics. The stiffness of each edge within a mesh was calculated basing on an angle between this edge and the relevant vector within a vector-field. That resulted in realistic simulation, which differentiated bending characteristics along the grain and perpendicular to the grain. Uneven connection of several layers of active-bended veneer allows to accumulate local stresses and pre-program bending characteristics of the structure. As a result active-bended structure forms particular predefined and predesigned shape and possesses locally variable stiffness and flexibility. The project applies this strategy to the design of the pavilion located within the urban context of a public space.

summary Education relies on a variety of media and participatory activities to deliver knowledge. The recent shift from in-person to virtual learning, led to a dual-stream approach of several challenges, having great impact on the quality of education and student engagement, limiting collaboration and the immersiveness of learning. This paper proposes an alternative gamified online platform designed for architectural education within a Metaverse framework. Eduverse leverages game-engine technology offering a multi-layered infrastructure that combines computational methods, content creation, and user experience design, re-envisioning the conventional curriculum. The effectiveness of the system is assessed by comparing it against existing digital pedagogy literature, and through qualitative analysis of user feedback after testing a live version of the system.

title Limits of Expression: On Digitizing Sentimental Touch
source ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 1: Projects Catalog of the 43rd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 68-73.
summary At the center of this project is a touch-sensitive garment (the Tactical Jacket) which aims to capture the many conscious and unconscious touch expressions we deploy in the course of daily life, with ourselves and others in our communities. The touch data gathered by this garment goes towards the development of a methodology for understanding how the body expresses emotion through touch, in communication with itself, and with other bodies. This research is motivated by the perpetual digital togetherness afforded by our modern communications networks that have perhaps dulled our sensitivities to the physical realm of human experience. As we continue to move further away from physical togetherness, engaging instead in long distance virtual communications as the default, we may lose an understanding of the emotional depth afforded by physical togetherness. The Tactical Jacket intends to bridge the gap between physical and digital means of communication currently available to us, and act as a tool to help bring light to the hidden emotional depths of our physical-touch behaviors.

summary To meet the urgent need of education in environmentally responsive architecture, the Architecture Department of The Chinese University of Hong Kong has organized lectures and studios to provide students with knowledge and hands-on experience in environmental design strategies. Considering the context of Hong Kong with a hot-humid sub-tropical climate and hyper-dense urban environment, the current approach in the design studio education has been mainly based on intuition with very limited supports in terms of technical know-how and scientific evidence. Many students of architecture tend to follow established paradigms that have evolved through experience with similar projects. In this paper, we report the research findings of a pilot study that applied advanced scientific simulation skills in studio education designed to help students explore environmental design strategies during early stages of project design development.

summary Although Computer-Aided Architectural Design tools have been introduced to studios for design visualization and communication, tangible models constructed by cardboard or other modeling materials still play an important role in assisting students on developing their conceptual framework related to spatial organization. A Rapid Prototyping (RP) system could provide a paradigm shift from the existing workflow of hand-made architectural model into an automated computer-aided manufacturing (CAM) environment. The introduction of computer controlled manufacturing technology will not limit the use of current conventional model making, and it will provide new capabilities for precise scaled model making and the possibility to generate free-form surface models for design representation. Because the technical capabilities of RP system could dramatically change the design workflow, the computer-aided manufacturing approach for architectural design has been adopted by overseas and local academic institutions. In this paper, we report the findings of a pilot study that applied rapid prototyping technology in architectural design education for helping students exploring an automated computer-aided manufacturing environment during early stage of design development.

summary This paper investigates a voxel-based approach to automate the space construction of an ill-defined building information model, namely, a building model without specific spatial definitions. The objective is to provide a simplified representation through clustering voxels to reconstruct spaces, with which a spatial topological algorithm is designed to infer the implicit connectivity. This approach is treated as the first step to automate building information exchange for building performance simulation and knowledge-intensive reasoning.

title Syntactic structures
source The Hague : Mouton
summary Noam Chomsky's first book on syntactic structures is one of the first serious attempts on the part of a linguist to construct within the tradition of scientific theory-construction a comprehensive theory of language which may be understood in the same sense that a chemical, biological theory is understood by experts in those fields. It is not a mere reorganization of the data into a new kind of library catalogue, nor another specualtive philosophy about the nature of man and language, but rather a rigorus explication of our intuitions about our language in terms of an overt axiom system, the theorems derivable from it, explicit results which may be compared with new data and other intuitions, all based plainly on an overt theory of the internal structure of languages; and it may well provide an opportunity for the application of explicity measures of simplicity to decide preference of one form over another form of grammar.

title Feeling Like Humans Low-cost wearable sensors for design research in the age of AI

summary Spatial emotions have played a critical role in visual-spatial environmental assessment, which can be evaluated using wearable physiological sensors. However, information on virtual spatial sequence assessment with quantitative emotional responses needs to be more comprehensive in the literature. Thus, designers' ability to assess sequential space experiences quantitatively and cost-effectively is limited before the design is finalized. This research measures the emotions expressed while walking in virtual reality (VR) with different spatial parameters using electroencephalograms (EEGs) and electrodermal activity (EDA). Twenty-six subjects experienced three 3D scanned virtual spaces with a VR headset (Quest 2 device) corresponding to the sequential space parameters of different shapes, heights, widths, and lengths. Simultaneously, the EEGs and EDA measured the subjects' responses during their virtual walking. We visualized their physiological data to compare the consistencies among the virtual spatial sequences and human feelings in the VR experiences. Experimental results show that the parameter changes of VR spatial sequences can arouse EDA signals and significant fluctuations in the five frequency ranges of brain waves. Specifically, in terms of VR spaces and emotions, the experiments find that walking virtually from higher to lower spaces increases Alpha and Beta brain wave activity in AF7 and AF8. This research attempts to offer a useful emotion measurement tool in virtual architectural design using multi-physiological sensors, potentially empowering AI human reaction prediction in the future.

summary Spatial emotions have played a critical role in visual-spatial environmental assessment, which can be assessed using bio-sensors and language description. However, information on virtual spatial emotion assessment with objective emotion labels and natural language processing (NLP) is insufficient in literature. Thus, designers’ ability to assess spatial design quantitatively and cost effectively is limited before the design is finalized. This research measures the emotions expressed using electroencephalograms (EEGs) and descriptions in virtual reality (VR) spaces with different parameters. First, 26 subjects experienced 10 designed virtual spaces with a VR headset (Quest 2 device) corresponding to the different space parameters of shape, height, width, and length. Simultaneously, the EEG measured the emotions of the subjects using four electrodes and the five brain waves. Second, two labels – calm and active – were produced using EEGs to describe these virtual reality spaces. Last, this labeled emotion dataset compared the differences among the virtual spaces, human feelings, and the language description of the participants in the VR spatial experience. Experimental results show that the parameter changes of VR spaces can arouse significant fluctuations in the five brain waves. The EEG brain wave signals, in turn, can label the virtual rooms with calm and active emotions. Specifically, in terms of VR spaces and emotions, the experiments find that more relative spatial height results in less active emotions, while round spaces arouse calmness in the human brain waves. Moreover, the precise connection among VR spaces, brain waves in emotion, and languages still needs further research. This research attempts to offer a useful emotion measurement tool in virtual architectural design and description using EEGs. This research identifies potentials for future applications combining physiological metrics and AI methods, i.e., machine learning for synthetic design generation and evaluation.

The purpose of the plug-in is to create a computational tool that generates unique urban block alternatives by mimicing the site’s built environment. The neccessity to create such a tool has stemmed from observations of physically un-harmonious neighbourhoods. This tool is claimed as the initial phase of a new urban tool that generates urban blocks that respond to their built environment and help establish harmonious neighborhoods.

summary This paper presents a methodology to implement data-driven thinking in the context of urban design. We conducted a 7-day workshop with international students from landscape design and architecture backgrounds, with the objective of designing an experimental setup to measure real-time urban spaces, immediate environment, and body responses. The goal of the workshop was to expose participants to data-driven thinking through experimental design, multi-sensor data collection, data analysis, visualization, and insight generation. We made use of mixed methods, including validated pre- and postquestionnaires, and content analyses of the visualizations and results generated by the participants. The evidence suggest that the workshop resulted in an increase in participants’ knowledge about measuring, visualizing and understanding data of the surrounding built environment.

summary An architectural community of practice is formed by designers working together on a common goal. Members of this community share a common professional language where the vocabulary of this language represents a shared understanding. Members of a community of practice operate both by recording common knowledge into documents and by actively participating in social processes in order to personally contextualize this recorded knowledge. ArcIMap is a framework, consisting of a method and a computational model, that facilitates communities of practice to acquire, represent, share and reusedesign information and knowledge, and targets the creation of situated digital environments where teams of designers communicate and collaborate using this information and knowledge. This paper describes ArcIMap, its background, and one of its implementations for a community of practice working on an urban renewal project in an educational context.

summary When creating new kinds of origami, people design origami creases pattern on 2D plane. Consequently, people unable to precisely envision the 3D folded shape. However, in architecture, civil engineering and industrial applications, an accurate layout is important. This research is to compile an algorithm for creating origami forms with developability and flat-foldability on the target surface, more specifically, by setting a target surface first, generating a Miura-ori tessellation from the geometric configuration of a target surface. We achieve creating origami forms on a target surface, so that we can generate architectural surfaces with folded structure and accurately layout for construction. Our approach facilitates designing a free-form origami structure upon parametric and 3D modelling software for artists, designers and architects.
