title	TEAnO or the computer assisted generation of manufactured aesthetic goods seen as a constrained flux of technological unconsciousness
source	International Conference on Generative Art
summary	TEAnO (Telematica, Elettronica, Analisi nell'Opificio) was born in Florence, in 1991, at the age of 8, being the direct consequence of years of attempts by a group of computer science professionals to use the digital computers technology to find a sustainable match among creation, generation (or re-creation) and recreation, the three basic keywords underlying the concept of “Littérature potentielle” deployed by Oulipo in France and Oplepo in Italy (see “La Littérature potentielle (Créations Re-créations Récréations) published in France by Gallimard in 1973). During the last decade, TEAnO has been involving in the generation of “artistic goods” in aesthetic domains such as literature, music, theatre and painting. In all those artefacts in the computer plays a twofold role: it is often a tool to generate the good (e.g. an editor to compose palindrome sonnets of to generate antonymic music) and, sometimes it is the medium that makes the fruition of the good possible (e.g. the generator of passages of definition literature). In that sense such artefacts can actually be considered as “manufactured” goods. A great part of such creation and re-creation work has been based upon a rather small number of generation constraints borrowed from Oulipo, deeply stressed by the use of the digital computer massive combinatory power: S+n, edge extraction, phonetic manipulation, re-writing of well known masterpieces, random generation of plots, etc. Regardless this apparently simple underlying generation mechanisms, the systematic use of computer based tools, as weel the analysis of the produced results, has been the way to highlight two findings which can significantly affect the practice of computer based generation of aesthetic goods: ? the deep structure of an aesthetic work persists even through the more “desctructive” manipulations, (such as the antonymic transformation of the melody and lyrics of a music work) and become evident as a sort of profound, earliest and distinctive constraint; ? the intensive flux of computer generated “raw” material seems to confirm and to bring to our attention the existence of what Walter Benjamin indicated as the different way in which the nature talk to a camera and to our eye, and Franco Vaccari called “technological unconsciousness”.

title	Design creativity in emerging technologies
source	In Von, H., Stocker, G. and Schopf, C. (Eds.), Takeover: Who’s doing art of tomorrow (pp. 41-54), New York: SpringerWein.
summary	Human creativity works best when there are constraints – pressures to react to, to shape, to suggest. People are generally not very good at making it all up from scratch (Laurel, 1991). Emerging technology particularly virtual reality (VR) Multimedia and Internet is yet to be fully discovered as it allows unprecedented creative talent, ability, skill set, creative thinking, representation, exploration, observation and reference. In an effort to deliver interactive content, designers tend to freely borrow from different fields such as advertising, medicine, game, fine art, commerce, entertainment, edutainment, film-making and architecture (Rafi, Kamarulzaman, Fauzan and Karboulonis, 2000). As a result, content becomes a base that developers transfer the technique of conventional medium design media to the computer. What developers (e.g. artist and technologist) often miss is that to develop the emerging technology content based on the nature of the medium. In this context, the user is the one that will be the best judge to value the effectiveness of the content. The paper will introduce Global Information Infrastructure (GII) that is currently being developed in the Asian region and discuss its impact on the Information Age society. It will further highlight the ‘natural’ value and characteristics of the emerging technologies in particular Virtual Reality (VR), Multimedia and Internet as a guidance to design an effective, rich and innovative content development. This paper also argues that content designers of the future must not only be both artist and technologist, but artist and technologist that are aware of the re-convergence of art and science and context in which content is being developed. Some of our exploration at the Faculty of Creative Multimedia, Multimedia University will also be demonstrated. It is hoped that this will be the evidence to guide future ‘techno-creative designers’.

title	ICAtect: Integrating Design Tools for Preliminary Architectural Design
source	Wellington, New Zealand: Computer Science Department, Victoria University
summary	ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.

title	A Common Data Model for Computer Integrated Building
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : some ill. includes bibliography
summary	The connection of various building performance evaluation tools in a collaborative way is an essential request to develop true CAD systems. It is a basic requirement for the future of integrated information systems for building projects, where data concerning multiple aspects of the project can be exchanged during the different design steps. This paper deals with the on-going research concerning the generation of a common data model in the framework of a European collaborative action, the COMBINE Project, which is supported by the CEC, General Directorate XII for Research Science and Development, within the JOULE programme. The first step of the research concerns the progressive construction of a conceptual model and the paper focuses on the development of this Integrated Data Model (IDM). The paper reports on the definition of the architecture of the IDM. The main issues and the methodology of the IDM development are presented. The IDM development methodology is based on successive steps dealing with the identification of the data and context which are considered by the Design Tool Prototypes (DTP) to be connected through the IDM, the conceptual integration of this knowledge, and the implementation of the model on an appropriate software environment

title	Organizational Learning and Communities-of-Practice: Toward a Unified View of Working, Learning, and Innovation
source	Organization Science, 2(1), 40-57
summary	Recent ethnographic studies of workplace practices indicate that the ways people actually work usually differ fundamentally from the ways organizations describe that work in manuals, training programs, organizational charts, and job descriptions. Organizations tend to rely on the latter in their attempts to understand and improve work practice. We relate the conclusions of one study of work practices to compatible investigations of learning and innovation to argue that conventional descriptions of jobs mask not only the ways people work, but also the learning and innovation generated in the informal communities-of-practice in which they work. By reassessing the apparently conflicting triad of work, learning, and innovation in the context of actual communities and actual practices, we suggest that the synergistic connections between these three become apparent. With a unified view of working, learning, and innovating, it should be possible to reconceive of and redesign organizations to improve all three.

title	Handbook of genetic algorithms
source	Van Nostrand Reinhold, New York
summary	This book sets out to explain what genetic algorithms are and how they can be used to solve real-world problems. The first objective is tackled by the editor, Lawrence Davis. The remainder of the book is turned over to a series of short review articles by a collection of authors, each explaining how genetic algorithms have been applied to problems in their own specific area of interest. The first part of the book introduces the fundamental genetic algorithm (GA), explains how it has traditionally been designed and implemented and shows how the basic technique may be applied to a very simple numerical optimisation problem. The basic technique is then altered and refined in a number of ways, with the effects of each change being measured by comparison against the performance of the original. In this way, the reader is provided with an uncluttered introduction to the technique and learns to appreciate why certain variants of GA have become more popular than others in the scientific community. Davis stresses that the choice of a suitable representation for the problem in hand is a key step in applying the GA, as is the selection of suitable techniques for generating new solutions from old. He is refreshingly open in admitting that much of the business of adapting the GA to specific problems owes more to art than to science. It is nice to see the terminology associated with this subject explained, with the author stressing that much of the field is still an active area of research. Few assumptions are made about the reader's mathematical background. The second part of the book contains thirteen cameo descriptions of how genetic algorithmic techniques have been, or are being, applied to a diverse range of problems. Thus, one group of authors explains how the technique has been used for modelling arms races between neighbouring countries (a non- linear, dynamical system), while another group describes its use in deciding design trade-offs for military aircraft. My own favourite is a rather charming account of how the GA was applied to a series of scheduling problems. Having attempted something of this sort with Simulated Annealing, I found it refreshing to see the authors highlighting some of the problems that they had encountered, rather than sweeping them under the carpet as is so often done in the scientific literature. The editor points out that there are standard GA tools available for either play or serious development work. Two of these (GENESIS and OOGA) are described in a short, third part of the book. As is so often the case nowadays, it is possible to obtain a diskette containing both systems by sending your Visa card details (or $60) to an address in the USA.

title	Multi-Faceted, Dynamic Representation of Design Knowledge
source	ARCC Conference on Reflections on Representations. September, 1991. [16] p. : ill. includes bibliography
summary	Explicit representation of design knowledge is needed if scientific methods are to be applied in design research, and if computers are to be used in the aid of design education and practice. The representation of knowledge in general, and design knowledge in particular, have been the subject matter of computer science, design methods, and computer-aided design research for quite some time. Several models of design knowledge representation have been developed over the last 30 years, addressing specific aspects of the problem. This paper describes an approach that recognizes the multiplicity of design knowledge representation modalities and the dynamic nature of the represented knowledge. It uses a variety of computational tools to encode different aspects of design knowledge, including the realities, perceptions and the intentions it comprises. The representation is intended to form a parsimonious, communicable and presentable knowledge- base that can be used as a tool for design research and education

title	Is Design Really Social
source	Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 8 p.
summary	There are many who will readily agree with Mitchell’s assertion that “the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process.” [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants; that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided; therefore; must permit the best communication and the best social interaction. We think it essential to examine the foundations and assumptions on which software and environments are designed to support collaborative design communication. Of particular interest to us in this paper is the assumption about the “social” nature of design. Early research in computer-assisted design collaborations has jumped immediately into conclusions about communicative models which lead to high-bandwidth video connections as the preferred channel of collaboration. The unstated assumption is that computer-supported design environments are not adequate until they replicate in full the sensation of being physically present in the same space as the other participants (you are not there until you are really there). It is assumed that the real social process of design must include all the signals used to establish and facilitate face-to-face communication; including gestures; body language and all outputs of drawing (e.g. Tang [1991]). In our specification of systems for virtual design communities; are we about to fall into the same traps as drafting systems did?

summary	Designing is a complicated human behaviour and method, and is often treated as a mysterious "black box” operation in human mind. In the early period as for theory-studying of design thinking, the way of thinking that the researchers took were mostly descriptive discussions. Therefore, they lacked direct and empirical evidence although those studies provided significant exploration of design thinking (Wang, 1995). In recent years as for the study of cognitive science, they have tried to make design "glass box”. That is to try to make the thinking processes embedded in designers publicized. That is also to externalize the design procedure which provided the design studies another theoretical basis of more accurate and deeply researched procedure (Jones, 1992). Hence the studying of design thinking has become more important and the method of designing has also progressed a lot. For example, the classification of the nature of design problem such as ill-defined and well-defined (Newell, Shaw, and Simon, 1967), and different theoretical procedure modes for different disciplines, such as viewing architectural models as conjecture-analysis models and viewing engineering models as analysis-synthesis (Cross, 1991).

title	Modeling the structure of the flow experience
source	INFORMS Marketing Science and the Internet Mini-Conference, MIT
summary	The flow construct (Csikszentmihalyi 1977) has recently been proposed by Hoffman and Novak (1996) as essential to understanding consumer navigation behavior in online environments such as the World Wide Web. Previous researchers (e.g. Csikszentmihalyi 1990; Ghani, Supnick and Rooney 1991; Trevino and Webster 1992; Webster, Trevino and Ryan 1993) have noted that flow is a useful construct for describing more general human-computer interactions. Hoffman and Novak define flow as the state occurring during network navigation which is: 1) characterized by a seamless sequence of responses facilitated by machine interactivity, 2) intrinsically enjoyable, 3) accompanied by a loss of self-consciousness, and 4) selfreinforcing." To experience flow while engaged in an activity, consumers must perceive a balance between their skills and the challenges of the activity, and both their skills and challenges must be above a critical threshold. Hoffman and Novak (1996) propose that flow has a number of positive consequences from a marketing perspective, including increased consumer learning, exploratory behavior, and positive affect."

title	Digital ontology and the architectural monstrous

summary	This paper aims to connect a reading of Francisco Goya’s painting Vuelo de Brujo with Marco Frascari’s metaphorical exploration of the idea of ‘monstrosity’ in architecture in Monsters of Architecture (1991). It also seeks to connect these works to contemporary forms of digital monstrosity and the proposition that the existential anxiety explored within current digital representations of the monstrous have both their basis in the technical apparatus within which they are created, and current thinking on material realism in ontology. Given the emergence of complex forms of ‘life’ within Cellular Automata studies and the speculations regarding digital ontology stemming from Stephen Wolfram’s New Kind of Science, the paper also asks what the consequences of large-scale expansions of these capabilities will entail in a post-Singularity scenario.

doi	https://doi.org/10.52842/conf.ecaade.1999.169
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.

summary	Due to improving technology and global competition today sky is the only limit for high towers of metropolitan areas. The increase in number of high rise has been ruining the silhouette of cities all over the world like Istanbul, whose identity and image have also been destroyed by skyscrapers dominating the seven slopes on which it was once built. The urbanization in Istanbul has somehow become homogenous and destructive over the topography. Despite of raising debates on the critical issue now and then, no analytical approach has ever been introduced. The research therefore, aims to analyze the change of Bosphorus silhouette caused by the emergence of high rise blocks in Zincirlikuyu-Maslak route since it was defined as a Central Business District and a high rise development area by Bosphorus Conservation Law in 1991. ArcGIS Desktop software and its analyst extensions are used for mapping, analyzing and evaluating the urban development within years. The application is considered to be the initial step for a decision support system which will assist in assigning ground for high rise buildings in Istanbul.

summary	To begin with, I would like to say a few words about the problem of alienation of modern technologies which we also inevitably faced while starting teaching CAD at our department. Quite often nowadays a technology becomes a fetish as a result of lack of clear goals in human mind. There are multiple technologies without sense of purpose which turned into pure experiments. There is always the danger of losing purposeness and drifting toward alienation. The cause of the danger lies in forgetting about original goals while mastering and developing the technology. Eventually the original idea is ignored and a great gap appears between technical factors and creativity. We had the danger of alienation in mind when preparing the CAAD curriculum. Trying to avoid the tension between technical and creative elements we agreed not to introduce CAD too soon then the fourth year of studies and continue it for two semesters. One thing was clear - we should not teach the technique of CAD but how to design using a computer as a medium. Then we specified projects. The first was called "The bathroom I dream of" and meant to be a 2D drawing. The four introductory meetings were in fact teaching foundations of DOS, then a specific design followed with the help of AutoCAD program. In the IX semester, for example, it was "A family house" (plans, facades, perspective). "I have to follow them - I am their leader" said L.J. Peter in "The Peter's Prescription". This quotation reflects exactly the situation we find ourselves in teaching CAAD at our department. It means that ever growing students interest in CAAD made us introduce changes in the curriculum. According to the popular saying, "The more one gets the more one wants", so did we and the students feel after the first semester of teaching CAD. From autumn 1991 CAAD classes will be carried from the third year of studying for two consecutive years. But before further planning one major steep had to be done - we decided to reverse the typical of the seventies approach to the problem when teaching programming languages preceded practical goals hence discouraging many learners.

summary	The rapid advances in sensor technology and processing hardware make the development of a Digital Photogrammetric System for Architectural Photogrammetry possible. This system is able to acquire images with sufficient resolution for Architectural Photogrammetry. Geometric and topologic information for a CAAD-System can be derived with manual and/or semi-automated methods. This paper describes the current status of such a system which is under development at the Institute of Geodesy and Photogrammetry in cooperation with the Chair of Architecture and CAAD, both at the Swiss Federal Institute of Technology in Zurich.

source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

summary	Building IT2000 is a Building and Information Technology database which is presented in Hypertextformat. Its production has been co-ordinated by the CICA (the Construction Industry Computer Association), an independent association serving the needs of computer users, specifiers and suppliers in the Construction Industry. The stack is a collection of structured information prepared by a group of experts in computing and the construction industry. As such it represents an interesting advance from two points of view: (1.) It is a valuable source of information in its own right. It could provide a resource for students of architecture which could be used as a self-teaching package. (2.) It points a possible way forward for the development of similar hypertext based teaching packages which could be developed by academics within the European teaching community.

title	Analogical and inductive reasoning in architectural design computation
source	Swiss Federal Institute of Technology, ETH Zurich
summary	Computer-aided architectural design technology is now a crucial tool of modern architecture, from the viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that designers can apply to a project is constantly increasing. This requires development of more advanced knowledge acquisition technology to achieve higher functionality, flexibility, and efficient performance of the knowledge-based design systems in architecture. Human designers do not solve design problems from scratch, they utilize previous problem solving episodes for similar design problems as a basis for developmental decision making. This observation leads to the starting point of this research: First, we can utilize past experience to solve a new problem by detecting the similarities between the past problem and the new problem. Second, we can identify constraints and general rules implied by those similarities and the similar parts of similar situations. That is, by applying analogical and inductive reasoning we can advance the problem solving process.The main objective of this research is to establish the theory that (1) design process can be viewed as a learning process, (2) design innovation involves analogical and inductive reasoning, and (3) learning from a designer's previous design cases is necessary for the development of the next generation in a knowledge-based design system. This thesis draws upon results from several disciplines, including knowledge representation and machine learning in artificial intelligence, and knowledge acquisition in knowledge engineering, to investigate a potential design environment for future developments in computer-aided architectural design. This thesis contains three parts which correspond to the different steps of this research. Part I, discusses three different ways - problem solving, learning and creativity - of generating new thoughts based on old ones. In Part II, the problem statement of the thesis is made and a conceptual model of analogical and inductive reasoning in design is proposed. In Part III, three different methods of building design systems for solving an architectural design problem are compared rule-based, example-based, and case-based. Finally, conclusions are made based on the current implementation of the work, and possible future extensions of this research are described. It reveals new approaches for knowledge acquisition, machine learning, and knowledge-based design systems in architecture.

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.
