title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title	Steps toward artificial intelligence
source	E.A. Feigenbaum & J. Feldman, eds., Computers and Thought (McGraw-Hill, New York) 406-450.
summary	The problems of heuristic programming-of making computers solve really difficult problems-are divided into five main areas: Search, Pattern-Recognition, Learning, Planning, and Induction. Wherever appropriate, the discussion is supported by extensive citation of the literature and by descriptions of a few of the most successful heuristic (problem-solving) programs constructed to date. The adjective "heuristic," as used here and widely in the literature, means related to improving problem-solving performance; as a noun it is also used in regard to any method or trick used to improve the efficiency of a problem-solving system. A "heuristic program," to be considered successful, must work well on a variety of problems, and may often be excused if it fails on some. We often find it worthwhile to introduce a heuristic method, which happens to cause occasional failures, if there is an over-all improvement in performance. But imperfect methods are not necessarily heuristic, nor vice versa. Hence "heuristic" should not be regarded as opposite to "foolproof"; this has caused some confusion in the literature.

summary	Throughout these pages are made known the persons, the projects and the books that have influenced my actions and that they will be mentioned in form underlined in this paper. I have to emphasize that since 1965 to 1970, and in the continuous search that I was accomplishing to find data and bibliography adapted to the topic of computer graphics, only two series of publications contained topics related to this matter at that time: one was the IBM Journal and the other series was the communications of the ACM. The purpose of this work is to make known an experience accomplished throughout 30 years of intense activity in finding new methods of drawing and design, based on the use of digital computers, mainly in Argentina, and during certain periods of time in Great Britain and since 1971 during short visits to the United States and also in France. The first idea emerged in the year 1965 when I was assistant teacher at the School of Architecture of the University of Buenos Aires, as a combination of ideas between the concepts of spatial geometry and the current morphological studies that we taught in the Course of professor Gaston Breyer. However the idea of automatic drawing emerged observing the operation of the first scientific digital computer installed in the Computing Institute of the Faculty of Sciences of the University of Buenos Aires in 1963 (Sadosky 1963). At the beginning, the approach to the computer were not accomplished from a strictly scientific point of view, but it was implying a kind of "sincresis" (Koheler 1940) it is more than a synthesis, because I was tried to combine ideas that have had its origin in different worlds of thinking, the analogous world and the digital world, and this situation was very difficult to accept at that time.The designing procedures in the decade 1960's was deeply rooted (and still continues) in the architectural design field as a result of a drawing process based in heuristic techniques.

title	Sketchpad, A Man-Machine Graphical Communication System
source	Proceedings 1963 Spring Joint Computer Conference AFIPS, 1963: Vol. 23
summary	The Sketchpad system makes it possible for a man and a computer to converse rapidly through the medium of line drawings. Heretofore, most interaction between man and computers has been slowed down by the need to reduce all communication to written statements that can be typed; in the past, we have been writing letters to rather than conferring with our computers, For many types of communication, such as describing the shape of a mechanical part or the connections of an electrical circuit, typed statements can prove cumbersome. The Sketehpad system, by eliminating typed statements (except for legends) in favor of line drawings, opens up a new area of man-machine communication.

title	USER PARTICIPATION IN DESIGN: TECHNIQUES FOR DIALOGUE
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 17-24
summary	Many projects in which users participate in the design process are merely examples of professionals communicating their ideas to their clients. Conventional computer systems can be powerful tools for helping designers to present design informations to lay audiences, but when combined with computer modelling and simulation, they create opportunities for users to construct their own sequences of images and thus explore designs from their own viewpoint. Building on extensive experience of traditional methods of user participation, this paper explores the use of narratives to create dialogues between users, designers and computers. The concept of "design stories" as a route to fully shared creativity is explained. The paper also argues that this approach is needed to bring into focus design issues that cannot be described or resolved by computer modelling alone.

summary	With the expanding wave of contemporary architecture inspired and informed by biomorphic design and biomimetic processes, the re-evaluation of work of Frederick Kiesler has become immanent. Throughout the mid 20th century he became increasingly interested in the relationship of natural form and structure to architectural space and organization. The Grotto for Meditation proposed in 1963 for New Harmony, Indiana commissioned by Mrs. Jane Blaffer-Owen was the culmination of his life’s work. Though the project was not realized, it embodies all of the influences of his time from surrealism to biology and cybernetic theory. Through our university and the Blaffer Foundation, we engaged in formal research and tectonic resolution of the project employing digital modeling and fabrication technologies at our College and in Houston where Mrs. Owen lives when she is not in New Harmony. We based this project on the full catalog of archival material made available to us with support from the Blaffer and Kielser Foundations. Our exploration also was influenced by discussions with Mrs. Blaffer-Owen who is still very interested in realizing this profoundly interesting and enigmatic project. Our university has opened the door to the opportunity that our reinterpreted Grotto become a permanent fixture on the campus next to a wetland landscape that it is currently under construction. Our research into Kiesler has engaged his esoteric concepts of “co-realism” and “continuous tension” as well as his early use of recursive geometry and biomorphic form in design. From reverse engineering and digital fabrication via 3D scanning to generative structural articulation, we are experimenting with a structural/spatial system that closely aligns with Kiesler’s originally proposed tile patterning dilated into a minimal structure. Our prototypes and the final version will be fabricated by one of the largest commercially for-hire water jet cutter in country and assembled on the site.

title	THE EMERGING DIGITAL STYLE: Attention shift in architectural style recognition
doi	https://doi.org/10.52842/conf.caadria.2006.x.g4f
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 633-635
summary	“Style” has long been an important index to observe the design thinking of designers in architecture. Gombrich (1968) defined style as a particular selection from the alternatives when doing things; Ackerman (1963) considered that a distiguishable ensemble of certain characteristics we call a style; Schapiro (1961) pointed out that style is constant forms, and sometimes the constant elements, qualities and expression; Kirsch (1998), Cha and Gero (1999) thought of style as a form element and shape pattern. As Simon and others referred to, style emerged from the process of problem solving, Chan (1994, 2001) ever devised a serious of experiments to set up the operational definitions of style, further five factors that relate to generating styles. Owing to that the greater part of sketches and drawings in the design process couldn’t be replaced by computer-aided design systems (Eisentraut, 1997), designers must shift between different problem-solving methods while facing different design problems. The purpose in this research is to discuss the influences of computer usage on style generation and style recognition: The employment of certain procedural factors that occurred in the design processes that using conventional media is different from the ones that using computer media? Do personal styles emerge while designers shifting between different media in the design processes? Does any unusual phenomenon emerge while accustomed CAD-systems designers recognizing a style?

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 526-532
summary	It can be argued that over the last thirty five years computer aided architectural design (CAAD) has made little impact in terms of aiding design. The paper provides a broadbrush review of the last 35 years of CAAD research and suggests that the SKETCHPAD notion that has dominated CAAD since 1963 is now a flawed concept. Then the discipline was replete with Modernist concepts of optimal solutions, objective design criteria and universal design standards. Now CAD needs to proceed on the basis of the Post Modern ways of thinking and designing opened up by digital techniques - the Internet, multimedia, virtual reality, electronic games, distance learning. Computers facilitate information flow and storage. In the late seventies and eighties the CAAD research community's response to the difficulties it had identified with the construction of integrated digital building models was to attempt to improve the intelligence of the computer systems to better match the understanding of designers. Now it is clear that the future could easily lie with CAAD systems that have almost no intelligence and make no attempt to aid the designer. Communication is much more central to designing than computing.

summary	Design projects that address the context of cultural heritage through materiality and narrative are perhaps more necessary in our time than in any other. In an age of rapid access to countless images stored in an ethereal, global, technical landscape such as the World Wide Web, the ability for students to engage narrative and materiality through direct sensory experience is vital. An active dialogue within and through a design process can and should address these phenomena.

title	Developing a New Approach of Computer Use ‘KISS Modeling’ for Design-Ideas Alternatives of Form Massing: A framework for three-Dimensional Shape Recognition in Initial Design Phases
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 745-756
summary	This research aims at developing a new approach called ‘KISS Modeling’. KISS is generally a rule of ‘Keep It Simple, Stupid’ that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ‘KISS Modeling’ that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research, however, does not employ totally concepts of shape recognition or shape understanding in Artificial Intelligence and psychology. The research, in summary, investigates and describes: 1) a new approach of computer use contributing to generating design-ideas alternatives of form massing in initial design phases, within a simple way that any designer can understand at single glance, 2) implementation of shape recognition for generative three dimensional forms, 3) function to generate different outputs from different recognition, and 4) case studies introduced through applications and functions of the three dimensional modeling system presented by the research. The research concluded that the introduced processes help the user improve the management of conceptual designing through facilitating a discourse of his/her modeling of design-ideas massing.

summary	The research attempts to defi ne and classify the design capabilities of architects into a basic framework. This defi nition will be useful in understanding and determining the types and nature of impact introduced by digital and manual media used during architecturaldesign process. The research consists of three parts. The First part reviews the main stages, tasks and activities of the architectural design process. The second part builds the proposed framework of design capabilities relating them to the specifi c tasks and activities conductedby the architect along the design process. The third part proposes some useful measures as to how to make use of the proposed framework in assessing the impact of media on the design capabilities of architects.

summary	Despite recent approaches to enable the mass customization of double curved faÃ§ade panels, there still exist challenges including waste reduction, accuracy, surface continuity, economic feasibility, and workflow disintegration. This paper proposes a computational approach for the design and fabrication of materially informed double curved faÃ§ade panels with complex geometry. This approach proposes an optimized workflow to generate customizable double curved panels with complex geometry and different material properties, and optimize fabrication workflow for waste reduction. This workflow is applied to four different fabrication techniques: (1) vacuum forming, (2) clay extrusion, (3) sectioning, and (4) tessellation. Four experiments are introduced to apply surface rationalization and optimization using Rhino and Grasshopper scripting. Upon simulating each of the four design-to-fabrication techniques through different iterations, the experiment results demonstrated how the proposed workflows produced optimized surfaces with higher levels of accuracy and reduced waste material, customized per type of material and surface complexity.

source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 157–164
summary	The Saudi government is taking the initiative to modernise the country and address critical challenges. One of its primary goals is to relieve the housing deficit. One of the challenges in supplying the houses is that potential inhabitants have denied and refused to accept them due to their design failing to meet their demands. Furthermore, the government suffers from providing high-quality housing in line with people’s needs because only a few enterprises can meet the client’s needs, but only at the price of lengthy planning and building times, in addition to increased construction expenses. This research aims to propose a mass customisation design-to-fabrication workflow, which targets environmental optimisation, reduction of construction time and reduced cost and incorporates client involvement. Our research method includes conducting a survey with Saudi Arabian architecture firms to collect data about contemporary clients’ needs, analysing and reviewing mass-customisation tools & techniques, developing a bespoke algorithm capable of mass-customising housing and evaluating the algorithm through design experiments. Our findings present the advantages and challenges of our tool as well as a shape grammar of mass customised floor plan solutions.

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	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

title	Wave-edge Modeling Method for Segmented Timber Plate Shell Structures: A computational tool for optimizing the bonding area of CLT joints
doi	https://doi.org/10.52842/conf.ecaade.2023.1.301
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 301–310
summary	The paper presents an algorithmic modeling tool for segmented timber shell structures made of glued wave-edge CLT plates. The goal is to provide a larger bonding area and thereby higher adhesive strength between plates, especially where a higher tension-resistant capacity is required. In addition to a number of contemporary research for exploring stereotomic modules, the inspiration is taken from the long history of the traditional glued finger joints in carpentry where they are used for providing higher interlocking capacity and adhesive strength. The structural performance of regular and glued finger joints is directly proportional to the bonding area between adjoining elements where they are interlocked and glued. Hence, expanding the shared faces would intrinsically magnify the structural performance of the glued finger joints. The paper presents the modeling method of a material-efficient, grain-informed, and structurally-optimized wedge edge joint system for the multi-shaped shell structures where the wave pattern is chosen for generating smoother fabrication toolpaths compared to any sharp-cornered pattern. The algorithm developed by the authors can efficiently maximize the glue bond by optimizing the wave-edge properties dynamically with respect to the geometric design, material system, and structural analysis within a feedback loop. The wave-edge properties directly affect the material waste and fabrication time and cost; therefore, the production parameters could be directly considered and controlled within the design process. The algorithm is able to produce the structural data model for the direct RFEM structural analysis, and fabrication data for automated production of multitude elements. The paper argues the application possibilities and limitations of the joint system for multi-shaped timber plate shells made of a multitude of geometrically-differentiated timber plates.

summary	Reciprocal timber systems have been widely studied, however they have never been directly applied to the segmented timber shell structures as cross bracing of the polygonal topologies. For the first time, this paper presents an innovative hybrid timber system developed for design and construction of the robotically-fabricated lightweight timber shell structures. The paper integrates two configurations of wood beams: polygonal framing and reciprocal bracing. While, the polygonal topology of facets enables a constant distance offset for the thickness of the shell, the reciprocal configuration allows for cross bracing of polygonal frames where diagonals within the polygons cannot directly connect corners due to geometric constraints resulted by the free-form surface structure of shell shapes. Joining the cross-bracing elements in the center of the polygons with a reciprocal node reduces the complexity of the connection system at nodes while demonstrating the high load-bearing capacity of joints to withstand structural loads throughout the structure, compared to connecting 5, 6 or 7 beams in a single point. The article discusses the application and limitations of the timber system while presenting the design-to-assembly process of a case study of the small-scale shell demonstrator with the maximum span of 7.5 meters made of 144 wood elements for each polygonal and reciprocal configurations. The results show that the timber system has a great capacity for the rapid and precise assembly and disassembly of prefabricated timber structures. Generation of similar but different solid elements, allowed for the development of a custom CAD data interface for the automated production of numerous pieces, where simple joint details are applied for both alignment and attachment of beams, reducing the design complexity and facilitate the construction phase. As the result, the fabrication process was completely carried out with only a saw blade in a multi-axis robotic fabrication set up that enables the rapid, precise, and accurate cuts and grooves. Both timber configurations generate a uniform distribution of beam size, meaning that the production process created only a minimal amount of offcuts that allows for the use of simple and cost-efficient, short solid wood pieces.
