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 Digital Architecture in CAD studio and Internet-based competition
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title Cognitive Biases and Precedent Knowledge in Human and Computer-Aided Design Thinking

summary Cognitive biases (illusions) and potential errors can occur when using precedent knowledge for analogical, pre-parametric and qualitative design thinking. This paper refers largely to part of a completed research (Bay 2001) on how heuristic biases, discussed by Tversky and Kahneman (1982) in cognitive psychology, can affect judgement and learning of facts from precedents in architectural design, made explicit using a kernel of conceptual system (Tzonis et. al., 1978) and a framework of architectural representation (Tzonis 1992). These are used here to consider how such illusions and errors may be transferred to computer aided design thinking.

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 Practices of Distributed Intelligence and Designs for Education
source Distributed Cognitions, edited by G. Salomon. New York, NY: CambridgeUniversity Press
summary v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."

summary When the shape of an object has been numerically defined, it is sometimes necessary to distort it to improve either its technical performance or its aesthetic appearance. After briefly recalling the major properties of space curves and surfaces defined by Bernstein polynomials, it is shown how the result can be automatically obtained by distorting an auxiliary triparametric set of references. The principle of an approximate method for high-order curves and surfaces is explained

title Architectural critique through digital scenariobuilding. Augmenting Architectural Criticism and Narrative
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 697-709
summary As an idea scenario-building has parallels the use of creative faking in related disciplines, most particularly, in contemporary art. The techniques involved in scenario-building and faking offer us enhanced ways of undertaking creative thinking and critical review of architecture and architectural projects. Critical review and theoretical analysis of architecture can be undertaken via a range of methods that Attoe (1978) classifies as Normative, Interpretive and Descriptive. Digital representation now offers us new ways of augmenting these critical styles in ways that have yet to be fully exploited, and possible means of exploitation are illustrated in this paper. In short the work described here shows how digital techniques can be used to enrich architectural investigation, critical reporting and debate.

title Color spaces for computer graphics
source Computer Graphics, vol. 12, pp. 20-25, August 1978
summary Normal human color perception is a product of three independent sensory systems. By mirroring this mechanism, full-color display devices create colors as mixtures of three primaries. Any displayable color can be described by the corresponding values of these primaries. Frequently it is more convenient to define various other color spaces, or coordinate systems, for color representation or manipulation. Several such color spaces are presented which are suitable for applications involving user specification of color, along with the defining equations and illustrations. The use of special color spaces for particular kinds of color computations is discussed.

summary A previously reported method for finding the points of intersection of a vector and a parametric surface patch is examined. However, before the point of intersection of a vector and a patch can be determined, it is necessary to find the patch (or patches) on a multipatch surface intersected by the vector. A technique is described for determining the patch or patches intersected by a vector, given the patches intersected by a single plane containing the intersecting vector. Once these have been found, the point of intersection can be determined and the distance to the multipatch surface obtained

Ô h)0*0*0*°° ÔŒ A model for decomposition of a multi-cell system into maximum intraconnected subsystems, and their recomposition in a hierarchical way, was developed. The system is presented as a graph, the vertices of which are the elements and the links are the relations between them. The algorithm for the decomposition is based on successive 'splitting' of the system into subsystems, by applying the minimal cut procedure

summary A procedure is described which generates dissections of rectangles into rectangular components in order to obtain solutions to space-allocation problems which are restricted through topological and dimensional constraints. Solutions are generated in two steps: step 1 determines basic geometric properties of the arrangements to be produced, and step 2 computes the dimensions of the spaces in such an arrangement. Both steps are based on `wall representations' of the solutions. These representations allow geometric relations and operations to be transformed into relations and operations defined on character strings. They furthermore allow the (possibly infinite) set of solutions to be systematically searched for a finite set of `principal options'. The importance linear-programming techniques for step 2 is described

doi https://doi.org/10.52842/conf.caadria.2003.855
summary The widespread application of prefabricated products in building has made prefabrication an indispensable part of building processes. In this context, instead of handling every detail by architects themselves, some parts of architectural design have been transferred to manufacturer-designers. This inevitably brings about problems in the integration of prefabricated products and the specific buildings they serve. As a result, collaboration between architects and manufacturer-designers takes place in building processes in various forms and extents (non-, semi-, and full-collaboration). In this study, we aim to investigate collaborative design process from the cognitive aspect of design generation between architects and manufacturer-designers in terms of project-related products design. By applying the Kernel of Conceptual System theory (Tzonis et al., 1978), we intend to set up two empirical models in terms of design differences' formation in collaborative design process based on a case study with seeking the answers for the following research questions: 1. What kinds of design differences are raised in design processes? 2. Why the design differences are raised in design processes? 3. What implications could be made in developing computational models to facilitate collaborative design between architects and manufacturer-designers?

title On the structure and use of issue systems in design
source University of California, Berkeley
summary The purpose of this dissertation is to explain and justify the concept of issue serving-systems as a new paradigm for descriptive and normative models of design processes. This paradigm is based in general on Horst Rittel's "Argumentative Planning Paradigm" and in particular on Rittel's "Issue-Based Information System" --IBIS-- method. Like IBIS, the issue serving-system concept views design as consisting of the raising and answering of various questions, called issues. The addition of the issue serving-system concept to IBIS is the claim that the serving relationship is the main means for structuring issues into a system for design. That relationship is the one in which an issue A serves an issue B, by which it is meant that the answering of A is useful in deriving the answer to B. Collections of issues structured by this relationship are labelled "issue serving-systems." In the dissertation it is explained that an issue servingsystem has a quasi-hierarchical structure and has as its function the answering of a P!L issue, i.e., an issue of the form, "What should this plan be." Two projects are undertaken in order to demonstrate the normative significance of the issue serving-system concept. The first is to show that the concept forms the basis of a variety of techniques for mechanical (algorithmic) generation of issues and answers. The second is to show how the concept provides criteria for determining which issues should be dealt with and in what order. In particular, it is argued that a topdown breadth-first order of raising issues is best. These conclusions are incorporated into procedures for design, and two applications of these procedures are described. One application involves use of an interactive computer program written by the author. The other involves a non-computerized version of the method.

summary This contribution presents the outcomes of a three-credit elective course offered at Lawrence Technological University’s College of Architecture and Design that involved a week-long travel experience in Rome with undergraduate and graduate students. The course used on-the-fly digital synthetic creations with AI text-to-image and image-to-image generation. The students collectively produced a disciplinary design-fiction tour book for a futuristic Rome, integrated into the city's historical layers. Inspired by the 1978 Roma Interrotta/Interrupted Rome project, the students reimagined the city using AI-informed storytelling to create altered narratives that explored common themes and critical insights. The digital tools allowed students to seamlessly blend AI-generated ideas with photos from the tour, linking historical contexts and contemporary design proposals. The critical use of AI served as a valuable tool in this process, educating designers on the importance of site-specific considerations and capturing the essence of a place through innovative creations informed by their experiences.
