title	The Studio CTH-A and the Searching Picture

summary	What happens during an architect’s search for the best solution? How does he (or she) begin, which tools are chosen, what happens when he comes to a standstill? The activities – sketching, discussions with other people, making models, taking walks to think, visits to the library, etc? What is an ordinary procedure and what is more specific? Do the tools have an impact on the final solution chosen? What happens during periods of no activity? Are they important? In which fields of activities are signs of the searching process to be found? In other words — what is the process of creative thinking for architects? Mikael Hedin and myself at Design Methods, Chalmers University of Technology, have started research into architects’ problem-solving. We have finished a pilot study on a very experienced architect working traditionally, without Cad (”The Bo Cederlöf Case”). We have started preliminary discussions with our second ”Case”, an architect in another situation, who has been working for many years with Cad equipment (Gert Wingårdh). For our next case, we will study a third situation – two or more architects who share the responsibility for the solution and where the searching is a consequence of a dialogue between equal partners. At present, we are preparing a report on theories in and methods for Searching and Creativity. I will give you some results of our work up till now, in the form of ten hypotheses on the searching process. Finally, I would like to present those fields of activity where we have so far found signs of searching. Our approach, in comparison with earlier investigations into searching (the most respected being Arnheim’s study on Picasso’s completion of the Guernica) is to collect and observe signs of searching during the process, not afterwards. We are, to use a metaphor, following in the footsteps of the hunter, recording the path he chooses, what marks he makes, what tools, implements and equipment he uses. For practising architects: a better understanding of what is going on and encouragement to try new ways of searching, for architectural students: better preparation and training for problem solving. It all began while we compared the different objects in our collection of sketches at the Chalmers STUDIO for Visualisation and Communication. (For some years, we have been gathering sketches by Alvar Aalto, Jorn Utzon, Ralph Erskine, Erik and Tore Ahlsén, Lewerenz, Nyrén, Lindroos, Wingårdh and others in a permanent exhibition). We observed similarities in these sketches which allowed us to frame ten hypotheses about the searching process.

title	Computer aided design: back to the drawing board
source	Proc. of Creativity and Cognition, Loughborough, April
summary	This paper argues that the role of Computer Aided Design (CAD) should be to enhance and extend paper-based working, rather than to replace it. Current CAD tools are little used in the early stages of designing. Paper is heavily used, with its physical properties supporting work practices that are not possible with CAD. This paper presents implications for the design of new computer-based tools drawn from observations of designers' work practices. A new system is described that integrates paper-based and computer-based working in the same physical space and supports the application of computation to images on paper.

title	The Combination of Design Media and Design Creativity _ Conventional and Digital Media
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.w5x
summary	Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.

title	Exploring Structural Morphology Using CAD
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.d1k
summary	Often in the design process the student's imagination is restricted by their inability to visualise, model or accurately sketch ideas for innovative structural systems. By using CAD as a design tool it is possible to explore the morphology of complex structures and to be able to produce perspective drawings of them with relative ease. Within AutoCAD there is a small library of standard three-dimensional objects and surfaces that can be called upon to generate more complex forms. However, to further facilitate the architectural design process, an extended library of innovative structural forms would allow the professional designer, or student, greater design freedom and any increase in the palette of structural forms available should stimulate creativity. As practical examples, the paper describes how students have been encouraged to experiment with the use of structures which can only be physically modelled with difficulty and which are also difficult to represent on the two- dimensional surface of the drawing board unless the geometry has previously been determined by the methods described. These are (i) Reciprocal Frame three-dimensional beam grillage structures and (ii) plate domes created from lattice structures by point-to- plane duality. The problem, of representation of these structures has been overcome, in the first case, by generating AutoLISP procedures to draw the complex three-dimensional geometrical form automatically in AutoCAD and, in the second case, by the development of the computer program CADual.

title	Understanding the AR-VR Based Architectural Design Workflow among Selected Danish Architecture Practices
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 381–388

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

title	Exploring and Illustrating
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.l5o
summary	CAD, in its usually available forms, is wonderful at illustrating proposed architectural objects. But, as I argued last year at the Barcelona meeting, it is not so good at helping us extend the richness and development of architectural ideas—at the "back of envelope" and other developmental Ievels—indeed, it is (for pragmatic reasons—and others) actually restrictive of change, what-if, suck-it-and-see, etc. I shall describe a work environment, which we have been developing since last year in Portsmouth, in which computing is used by students to assist the generation, testing and extension of ideas: in which exploring takes precedence over illustrating. The central notion of this environment involves the extension and manipulation, through co-operative sharing of a joint "resource base" of computer stored images (recognising origination rather than ownership), and (parts of) which may be copied and transformed by group members as they seek to develop, enrich and extend their ideas. Transformations may be intentional, but some occur through the limits of our computational medium such as compression losses, file formats, colour depth and resolution and are welcomed as a contribution made by the computing medium used. Images are located through a developing, shared filing system, picture search and history trace. The environment relies on a small suite of computers wile a powerful machine acting as a fileserver and undertaking central, computationally-intensive tasks. For this environment, we have chosen software carefully, and the choice will be described. We have also developed a small, but crucial program that traces developments in the shared resource base—in what is, in effect, our own, operational CyberSpace (as distinct from a Virtual Reality). Through these mechanisms, we believe we are able to evade the limitation set by Ross Ashby's "Law of Requisite Variety", thus expanding the creativity-base of participating designers (students). There are no "scientific results", but we believe the reasoning behind, and the activity and exploration of our environment is valuable in itself, and may be of interest to collegues.

title	Creativity and design as exploration
source	J.S. Gero and M. L. Maher (eds), Modelling Creativity and Knowledge-Based Creative Design, Lawrence Erlbaum Associates, pp. 139-175
summary	This paper considers the problem of creative design, and in particular the role of a priori knowledge or "prototypes" in the design process. A design problem is characterised as one in which both the objectives and the means available for achieving these objectives are (of necessity) initially only poorly defined. Some observations concerning the nature of design process based on this characterisation are presented, and a model of the design process as a knowledge-based exploration task described. The role of prototypes in organising this knowledge is examined, and the widely accepted view that prototypes can form the principle source of knowledge for creativity in design is challenged. In a final section we outline the structural principles of a representation scheme which aims to overcome of these difficulties and describe a design support system which uses this scheme to support the design process.

summary	Creativity is an important factor for innovators. According to Eguchi and Pinheiro (2008) the basis of design is innovation because of the use creative methodology. It’s important to remember that the word “project” comes from the Latin “proyectus”, meaning “a forward throwing action”. According to Ramos (2006), “educating for creativity is essential.” Beetlestone (2000), De Bono (1993), Munari (1997) and Pawlak (2000) argue that as we’re children we’re curious to find answers to everything, but that traditional schooling brakes the creativity. This research is a methodological test which aims to identify the reasons for student’s selection of specific creative tools used in university projects.

summary	Nature as complete entity having existed before us, having produced us, of which we are a part of and which reaches far beyond us and our knowledge stands both for productivity and product, for stones, earth, water, air, plants, animals, human beings, for energy as such. On account of his activity and his intellectual powers and faculties the human being represents the center of this interrelation comprising his vital space, being perceived by him either consciously or unconsciously, the structure and formation of which he changes, which in turn, however, significantly codetermines his behavior and also his development. Spatial effect analysis and spatial impact analysis take the cross- linked interrelations of nature into account and thus the correlated diverse interactions by means of integral representation, determine the direct and indirect as well as the immediate and mediate decisions as to space and furnish us with decision-conclusions by means of modifications. Based on the all-in-all outlook encompassing nature- mankind-space spatial impact also means in particular compatibility within systems giving due regard to the factor time. The following topics are treated within the framework of research: (1.) Elaboration of a methodical framework regarding research and development in the field of multimedia-implementation for environmental planning. (2.) Preparative work concerning implementation areas of multimedia focussing on urban & regional planning and architecture. (3.) Planning process and planning levels,furthermore in the fields of information and decision process and accompanying verification. (4.) Optimizing interaction of multimedia and environmental simulation. (5.) Definition of research- and development-requirements as far as subject-specific and EDP-technical aspects are concerned. (6.) Structurizing of projects regarding realization of framework of research.

title	Common Illumination between Real and Computer Generated Scenes
source	Proceedings Graphics Interface '93, pp. 254-262, 1993
summary	The ability to merge a real video image (RVI) with a computer- generated image (CGI) enhances the usefulness of both. To go beyond "cut and paste" and chroma-keying, and merge the two images successfully, one must solve the problems of common viewing parameters, common visibility and common illumination. The result can be dubbed Computer Augmented Reality (CAR). We present in this paper techniques for approximating the common global illumination for RVIs and CGIs, assuming some elements of the scene geometry of the real world and common viewing parameters are known. Since the real image is a projection of the exact solution for the global illumination in the real world (done by nature), we approximate the global illumination of the merged image by making the RVI part of the solution to the common global illumination computation. The objects in the real scene are replaced by few boxes covering them; the image intensity of the RVI is used as the initial surface radiosity of the visible part of the boxes; the surface reflectance of the boxes is approximated by subtracting an estimate of the illuminant intensity based on the concept of ambient light; finally global illumination using a classic radiosity computation is used to render the surface of the CGIs with respect to their new environment and for calculating the amount of image intensity correction needed for surfaces of the real image. An example animation testing these techniques has been produced. Most of the geometric problems have been solved in a relatively ad hoc manner. The viewing parameters were extracted by interactive matching of the synthetic scene with the RVIs. The visibility is determined by the relative position of the "blocks" representing the real objects and the computer generated objects, and a moving computer generated light has been inserted. The results of the merging are encouraging, and would be effective for many applications.

title	Generative Modelling and Electronic Lego
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q8a
summary	This paper shows work exemplifying the further extent of computer capabilities in the field of design. The work stems from a belief that for computers to be used effectively within the architectural profession their utility must stretch far beyond the process of description of geometric data, but be incorporated in the fundamental roots of design: that of conceptual design. Computers can be used to access the knowledge we have and then formulate this knowledge into a working language of design. Computers can be used to generate space and form in accordance with any relationship the designer may choose to set. This allows them to be used from the very conception of design. It is only by working from the very beginning, the very basis of the design of a building that we can fully develop the integration of computers in the construction industry. The work undertaken sets out primarily to explore one of the ways computers could be used in the field of architectural design. In recognition that an important byproduct of any design search is the enhanced understanding of the problem itself, the work was directed towards a particular project. This allowed each stage of thought to be to be considered as it arose and subsequently incorporated into the design model. The work does not attempt to automise the design process but simply tries to explore some of the opportunities offered by computers and see if they can be easily incorporated into the design process offering design solutions that may not otherwise have been considered. The exploration resulted in a simple design process model that incorporates the more accessible and useful aspects of computer technology.

source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.i6u
summary	The idea of artificial brains and artificial intelligence (AI) has been subject to criticism. The objection of J. Searle, for instance, which has been published in 1984 and which was partially directly addressed to one of the centres of AI, the Carnegie Mellon University in Pittsburgh, is mainly based on two points: (1) interactions between physiological and mental functions, and (2) the intentionality and context-relatedness of meaning. - With an emphasis on architectural design, this paper is about the second point, because the problem of meaning is a neuralgic point in the discussion of "artificial intelligence in design" (AID). Technical parameters are incompatible with mechanisms of meaning in any field of artistic, cultural or non-technical expression. This point, that is the relation between acts of meaning and acts of technical problem-solving and, connectedly, the relation between technological and architectural design, has been widely ignored in the discussion on AID. The development seems to be dominated by the tacit assumption that architecture can be articulated and generated purely in technical and formal terms of information processing beyond the field of architecture itself. Design and shape grammars have become a well established field in the discussion of AID, also with respect to architecture. But questions of architectural history and theory are touched on only incidentally and not sufficiently in this discussion. The problem is not, in other words, simply to include more or less unrelated cases of architecture, or architectural concepts -even if these are famous ones, such as Laugier's original hut for instance but to establish structural relations between arguments of architectural theory and arguments of AID.

source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Design decision support related to building energy consumption and/or indoor climate should be based on an integral approach to the environment, the building, heating, ventilating and air-conditioning (HVAC) system, and the occupants. The tools to achieve this are now available in the form of computer simulation systems which treat the building and plant as an integrated dynamic system. Although its potentials reach beyond the area of Computer Aided Building Design, the paper describes building and plant energy simulation within the context of CABD, design decision support and design evaluation. Currently, computer simulation is only used indirectly as a design decision support mechanism; that is, its power is not delivered very efficiently to the design profession. This paper suggests some future research directions. These are aimed at providing a mechanism to overcome this problem by developing an intelligent front end' which bridges the gap between sophisticated computer simulation tools and the design profession.

title	Information Technology in the Management of Design and Construction
source	Management of Information Technology for Construction (Ed: K Mathur et al) World Scientific, 585-594
summary	This paper provides an overview of the developments in Information Technology (IT) and its impact on the Architecture, Engineering and Construction (AEC) industry. It takes note of what has transpired in the last two decades and how the evolution of this subject corresponds to the predictions which had been made at various times in the past. It concludes that changes in procedures, processes and structure of organisations are needed if the most effective use of IT is to be achieved, and it is timely to go beyond solutions which mimic and automate current processes. Strategic frameworks must be defined within which new solutions will emerge rather than specific technical solutions for individual design or automation tasks. Concurrent changes in the AEC professions and the management of projects and organisations will be required to support the new tools and techniques offered by IT. Thus no promises should be made purely on the basis of emerging technologies. Hence the paper makes no attempt to predict the future of the AEC industry even though integrated systems may become available to support creative, cooperative, multi-disciplinary design, and though such systems will assist construction automation tasks, maintenance and facility management.

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	UI innovations are often driven by a combination of technology advances and application demands. On the technology side, advances in interactive computer graphics hardware, coupled with low-cost mass storage, have created new possibilities for information retrieval systems in which UIs could play a more central role. On the application side, increasing masses of information confronting a business or an individual have created a demand for information management applications. In the 1980s, text-editing forced the shaping of the desktop metaphor and the now standard GUI paradigm. In the 1990s, it is likely that information access will be a primary force in shaping the successor to the desktop metapho. This article presents an experimental system, the Information Visualizer (see figure 1), which explores a UI paradigm that goes beyond the desktop metaphor to exploit the emerging generation of graphical personal computers and to support the emerging application demand to retrieve, store, manipulate, and understand large amounts of infromation. The basic problem is how to utilize advancing graphics technology to lower the cost of finding information and accessing it once found (the information's "cost structure"). We take four broad strategies: making the user's immediate workspace larger, enabling user interaction with multiple agents, increasing the real-time interaction rate between user and system, and using visual abstraction to shift information to the perceptual system to speed information assimilation and retrieval.
