title	Supporting information navigation in generative design systems
source	Camegie Mellon University, School of Architecture
summary	Generative design systems make it easier for designers to generate and explore design altematives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed to enable designers to access the information with ease. Such aids may improve the usability of generative design systems and encourage their use in architectural practice. This dissertation presents a comprehensive approach to support navigation in generative design systems. This approach takes account of studies related to human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. It contains a general model of design space, basic navigation operations, and principles for designing navigation support. The design space model describes how the space may grow and evolve along predictable dimensions. The basic operations facilitate navigation activities in this multi-dimensional design space. The design principles aim at guiding system developers in creating navigation utilities tailored to the needs of individual design systems. This approach is validated through prototype implementations and limited pilot usability studies. The validity of the design space model and basic navigation operations is examined through the development of a design space navigation framework that encapsulates the model and operations in a software environment and provides the infrastructure and mechanisms for supporting navigation. Three prototype navigation tools are implemented using this framework. These tools are subjected to usability studies. The studies show that these tools are easy to leam and are efficient in assisting designers locating desired information. In summary, it can be demonstrated that through the prototype implementations and usability studies, this approach offers sufficient support for the design and implementation of navigation aids in a generative design system. The research effort is a pioneer study on navigation support in generative design systems. It demonstrates why navigation support is necessary; how to provide the support; and what types of user interaction it can offer. This research contributes to information navigation studies not only in the specific domain of generative design system research, but also in the general field of human-computer interaction.

title	Designing the Undesigned: Emergence as a tool for design
source	International Conference on Generative Art
summary	Design, as an act and a result, is a natural part of the larger biological context in which we live. It is both a behavior and a tangible side effect of the organic system from which it arises. A design can be characterized as a physical exemplar of the concept of memes, the 'genetic' building blocks of ideas or units of cultural transmission. In this capacity, design has served to extend humankind's reach and ensure and enrich humankind's survival in the full range and variability of conditions the Earth has to offer. In a very real sense, design has 'evolved' its own rich ecosystem, with a robust diversity of elements, dynamics, and interrelationships rivaling that of the organic system from which it derives. In the ecology of design, designs obey laws analogous to the laws of survival and selection that organisms in nature obey. Given the recent advances in understanding and modeling of the biological and physical systems, it is not surprising that artists and designers are now turning to these models as a 'new' resource for the conceptualization and design of structured artifacts and spaces. While there are many fundamental technical issues surrounding development and application of generative models and processes, the relationship of artist to the process of creation is a central issue in the scaling up and widespread accessibility/acceptance of the generative approach. This paper will present a set of observations from the perspective of a small company of artist/ technologists trying to bridge the commercial and artistic application of generative processes. Specifically, the paper will explore some approaches to the designer/system relationship and process control metaphor, the balancing of serendipity and design convergence, the definitions and representations of design spaces, and finally, present some ideas about the future prospects and promising new techniques for generative design.

summary	For now, the written word is still the most efficient communication method in network space (Anders, 1998). When designing a network space, it is necessary to let users know the concept of the space. Some researchers imitated physical space and brought a similar spatial experience into network space. The design of network space may be based on existing space in the real world. The rules of construction in physical space and network space are the same (Donath, 1997; Dyson, 1998). Consequently, the best way to explore network space is to imitate physical space (Mitchell, 1995, 1999a).

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	Shaping Structures
source	New York: John Wiley and Sons
summary	In Shaping Structures, an engineer and an architect, both longtime teachers of structures at major American universities, collaborate to present an inspired synthesis of the creative and the technical, explicating both the principles of statics and their application to the fascinating task of finding good form for structures. This richly visual volume features: * An easily understood development of the fundamentals of statics * Step-by-step demonstrations, using both numerical and graphical techniques, of simple yet powerful methods for finding form and forces for arched structures, suspended structures, cable-stayed structures, and highly efficient trusses * 120 photographs and more than 300 crisp drawings that illustrate and explain the magnificent structural triumphs of master architects and engineers -including Gustave Eiffel's famous tower, Robert Maillart's soaring bridges, Pier Luigi Nervi's landmark Turin Exhibition Hall, and many others * Calculations in both SI metric and conventional units throughout the book Requiring only the most rudimentary mathematical background yet accurate and fully functional, Shaping Structures provides an inviting point of entry to the study of structural design for engineering and architecture students -proving that the science of statics doesn't have to be lifeless, simplistic, or dull.

title	Possible Futures in Computer Art Generation
source	International Conference on Generative Art
summary	Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques Figure 3 Trellis interpreted with "graphic ivy" Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

title	Evolutionary Banners, exploring a generative design approach
source	International Conference on Generative Art
summary	This working paper reports pre-mature findings from an ongoing research project that uses Genetic Algorithms (GAs) to automate the design of objects in the World Wide Web (WWW). Digital communications technology has on the business side been conceptualized as electronic commerce (E-commerce). Digitization implies a new cost structure for message design, test and implementation. One important problem regards the use and effectiveness of different means for E-commerce market communications. The purpose with the research presented here is to experiment with a particular use of GAs in E-commerce retailing. It is not to look for an optimal algorithm or fine-tune its parameters. This paper contributes with findings and a discussion of a new E-commerce possibility – evolutionary banner design The scientific aim is to explore the value of such an approach. As well as identify important issues. In a soon-to-be-realized implementation, the commercial aim will be to increase the sales volume for a specific product. In a sense the evolutionary banner works as an artificial art director. Still, a human director is needed to design the banner organism, its genetic code and related parameters. And of course to develop more creative uses of the approach presented below.

title	Collaborative Architectural Design as a reflective Conversation: an agent facilitated system to support collaborative conceptual design
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In this paper, definitions of collaborative design are discussed and understood in terms of a designer’s cognitive collaborations to explore his/her experiential memory for remote idea associations. Based on Schon’s reflective practice theory, Valkenburg and Dorst’s (1998) description of collaborative team designing is adopted as a model for a proposed design conversation system. The design conversation system is aimed at triggering the experiential memory of the designer by associating significant ideas from different design domains to provide different perspectives of a design situation. The paper describes a proposed framework for the design conversation system incorporating computational agents in a blackboard architecture environment.

title	Cooperation Between Reactive 3D Objects and a Multimodal X Window Kernel for CAD
source	Bunt, H., Beun, R.J., Borghuis, T. (Eds.). Multimodal Human-Computer Communication : Systems, Techniques, and Experiments. Berlin : Springer
summary	From the early steps of sketching to final engineering, a frequent and very important activity in designing objects is to perform graphical and spatial simulations to solve the constraints on the objects which are being designed. But when we analyse work situations involving the use of CAD systems, it is today an acknowledged fact that these tools are not helpful to perform these types of simulations. While knowledge modeling based on form feature concepts already offers some possibilities for attaching behaviour to objects, the simulation activity requires in addition a `real time' and `intelligent' management of the interactions between the 3D virtual objects and the CAD user. Our general purpose is to study how future CAD systems could be improved to achieve the simulation steps of object design. In this context we present some issues concerning the cooperation between a model of reactive 3D objects and a multimodal X Window kernel. We have developed a prototype of a system where objects with reactive behaviour can be built, and with which the user can interact with a combination of graphical actions and vocal commands. This prototype is used to evaluate the feasability and the usefulness of the integration of such techniques in futur applications that would be used by object designers in a real working context. We describe the current state of this system and the planned improvements.

title	The architectural aspect of designing space in virtual environments
source	University of Strathclyde, Dept. of Architecure and Building Science
summary	This thesis deals with the architectural aspect of virtual environment design. It aims at proposing a framework, which could inform the design of three-dimensional content for defining space in virtual environments, in order to aid navigation and wayfinding. The use of such a framework in the design of certain virtual environments is considered necessary for imposing a certain form and structure to our spatial experience in there. Firstly, this thesis looks into literature from the fields of architectural and urban design theory, philosophy, environmental cognition, perceptual psychology and geography for the purpose of identifying a taxonomy of spatial elements and their structure in the real world, on the basis of the way that humans think about and remember real environments. Consequently, the taxonomy, proposed for space in the real world is adapted to the intrinsic characteristics of space in virtual environments, on the basis of human factors aspects of virtual reality technology. As a result, the thesis proposes a hypothetical framework consisting of a taxonomy of spatial and space-establishing elements that a virtual environment may comprise and of the possible structure of these elements. Following this framework, several pilot virtual environments are designed, for the purpose of identifying key design issues for evaluation. As it was impossible to evaluate the whole framework, six specific design issues, which have important implications for the design of space in virtual environments, are investigated by experimental methods of research. Apart from providing answers to these specific design issues, the experimental phase leads to a better understanding of the nature of space in virtual environments and to several hypotheses for future empirical research.

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.

source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 286-291
summary	The shape of buildings determines the relationships between the contained spaces with the contained activities. As shapes are represented by their perimeter, the form and the length of building perimeters is of particular interest to architectural design. This paper presents a short computer program oriented to the exploration of modular floor plans related to their perimeter. The characteristics of a class of orthogonal configurations called polyminoes has been taken as a basis for the programming work. Polyminoes are briefly presented in the first part of the paper as well as some data concerning their geometrical structure. The operation of the computer program illustrated by some working examples, is described in the last part of the paper. The results obtained can be used for comparison between alternative shapes. Additional information about these modular shapes is given together with every particular form so as to ease the evaluation task. In these terms the program must be seen as a tool of assessment rather than as a designing procedure.

title	Prototypical Laboratory Design to Support Learning and Teaching
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Collaboration between designers and scientists is an unusual combination to undertake the prototypical design of a teaching laboratory funded by Howard Hughes Medical Institute. The zoologists are developing a cooperative learning and interactive teaching pedagogy to make learningscience a process of critical inquiry and discovery. The industrial and interior designers are paying attention to the design issues of function and environmental support for teaching and doing the work required in a three-hour, hands-on beginning science learning space. Using both qualitative andquantitative research methods, the designers are able to determine a framework for making design decisions in prototypical beginning science environments. This framework is being developed as a guideline for designing similar environments at other institutions of higher learning. Videotape analysis precedes the research to uncover the underlying problems of the existing space and to formulate the questions for the research. Elements of a case study and an evaluative study integratewith the design process to form the basis of an intensive investigation of design issues for a beginning science teaching laboratory. Using two pretests as a baseline, the posttest data evaluates the success orfailure of the prototypical design. Both the pretests and the posttest evaluate the physical attributes of the old and new learning environment related to a beginning laboratory course in Zoology at Arizona State University.

title	Object representation and reasoning using halfplanes and logic
source	J.S. Gero and F. Sudweeks (eds), Artificial Intelligence in Design '98, Kluwer, Dordrecht, pp. 107-126
summary	Shapes and objects represent important ways with which to perceive and reason about the world. This paper develops a framework which uniformly encompasses both planar and non-planar surfaces to represent graphical objects in three dimensions. Based on the concept of halfspaces this framework allows the representation of volumes as predicates in logic. This representation is applied to demonstrate object concepts associated with reasoning about the topology of objects as individuals as well as groups of objects at the early, conceptual phase of designing. The example shows how both planar and non-planar boundaries of objects are treated uniformly.

doi	https://doi.org/10.52842/conf.ecaade.1998.234
summary	A computer program is being elaborated as an aid in designing assembled parts whose assembly presents high degrees of complexity. The newly created program, once incorporated in the CAD sector to increase its potential applications, will facilitate the analysis of reciprocal relationhips between pieces of the assemblage; this will enhance optimum decision-making in terms of geometric and functional characteristics with respect to the previously conceived assembly sequence. The program will automatically create images in three different ways: instantaneous images of assembly stages for each piece of the assembled part; exploded axonometric view of the whole structure with indications of necessary procedures for inserting or connecting the assembled part;sequenced procedures for connecting the assembled part. The different methods of visualization listed above will allow for project verification of the part by means of simultaneous visual analysis of the images and rapid updating should any changes in their properties arise. These types of visualization include simulations of piece by piece assemblage, which will facilitate an "optimal assemblage", meaning a set of components which are assembled in a specific sequence according to their "structural compatibility" and taking into consideration "particular assembly requirements".

title	Planning of Environments for People with Physical Disabilities Using Computer Aided Design
source	Lund Institute of Technology, School of Architecture
summary	In the area of environment adaptations for people with physical disabilities, it is of vital importance that the design is optimized considering the human-environment interactions. All involved persons in such a planning process must be given sufficient support in understanding the information, so that everyone can participate actively. There is an apparent risk that discussions will be kept between experts, due to difficulties in understanding the complex and technical adaptation issues. This thesis investigates the use of computer-based tools for planning/designing environments for physically disabled people. A software prototype, and a method to use such a tool in the planning process, was developed and evaluated, based on the findings from six case studies of real planning situations. The case studies indicated that although such a tool would support the design, as well as the dialog between the participants, a certain level of technical and economical efficiency must be obtained. To facilitate the professional planner's work, an important issue is to maintain a large library of 3D objects. With the latest prototype implementation, it was found that such a planning tool can be produced, even when using consumer-oriented computers. One previous critical factor, interactive manipulation of 3D objects, can now be achieved if utilizing modern graphic cards with 3D acceleration. A usability test was performed to evaluate the prototype's basic operations, involving two groups of future users: five occupational therapist students, and four persons with major physical impairments. It was found that although the usability was satisfactory for the basic tasks, several items needed to be improved or added in future versions. It is important with an integrated support for manikins, in order to evaluate, e.g., wheelchair accessibility, reach ability, positioning of handrails, etc. This thesis reviews and compiles published anthropometrical and biomechanical data into a uniform segment-by-segment structure, in order to aid the design and modifications of manikins. The compilation was implemented as a spreadsheet document. An MRI investigation of the neck-shoulder region was performed on 20 healthy Scandinavian, female volunteers, measuring various musculoskeletal properties. These measurements can be used for further refinements of manikin specifications and biomechanical models.

title	Hanging Roof Forms Research
source	Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 93-99
summary	This article presents a general description of the suspended roof forms. The concept covers all kinds of diaphragms, tents and cord nets. Depending on the roof construction, in particular the way of attachment, the used material or external factors, the roof forms undergo some decisive changes. The shape of the suspended roofs is difficult to define, especially in case of more complex roofs. Their surfaces are multi-curvature and do not comprise typical solids or geometrical forms, which make the design even more complicated. The shape of the surfaces is close to the minimal surfaces, i.e. those, which we would obtain form a bubble film spread over any limited outline. Unfortunately, the very designing, element dimensions as well as the tension design are still troublesome. Only the finite element method, if applied, allows the film form design. Nowadays, thanks to particular computer programmes, it is possible to simulate certain phenomena.
