title	How an Architect Created Design Requirements
source	G. Goldschmidt and W. Porter (eds), Design Thinking Research Symposium: Design Representation, MIT, Cambridge, pp. II.101-124
summary	There is an anecdotal view that designers, during a conceptual design process, not just synthesise solutions that satisfy initially given requirements, but also create by themselves novel design requirements that capture important aspects of the given problem. Further, it is believed that design sketches serve as a thinking tool for designers to do this. Then, what kinds of cognitive interaction with their own sketches enable designers to create novel requirements? The purpose of this paper is to answer this question. We examined the cognitive processes of a practising architect, using a protocol analysis technique. Our examinations focused on whether particular types of cognitive actions account for the creation of novel design requirements. We found that intensive occurrences of a certain type of perceptual actions, acts of establishing new relations or visual features on the sketches, are likely to co-occur with the creation of requirements. This suggests that this type of perceptual actions are the key constituent of acts of creating novel requirements, and therefore one of the important actions in sketching activities. This presents evidence of the view that designing is a situated act, as well as has an implication for design education.

title	Qualitative representation and reasoning about shapes
source	Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 55-68
summary	In this paper we present an approach to the qualitative representation of shape and its use. We use a qualitative coding scheme founded on landmarks in the shape. The scheme encodes a qualitative representation of angles, relative side lengths and curvatures at landmarks. We then show how such a representation can be used as a basis for reasoning about shapes using extracted shape features. We conclude with a preliminary analysis of 12 sketches of the architect Louis Kahn and show how they may be categorised based on these shape features.

title	The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source	College of Architecture, Georgia Institute of Technology
summary	Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

title	The Combination of Design Media and Design Creativity _ Conventional and Digital Media
doi	https://doi.org/10.52842/conf.caadria.2007.x.w5x
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
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	Cognitive Role of Ill-Structured Representations in Preliminary Design
source	Visual and Spatial Reasoning in Design, eds. J. S. Gero, and B. Tversky. Sydney: Key Centre of Design Computing and Cognition, University of Sydney
summary	I have previously argued that cognitive processes involved in preliminary design require "lateral" transformations or mental state shifts, and that "ill-structured" mental representations are necessary to support these transformations. I review the argument and provide additional support for it by appealing to some neuropsychological data.

title	Sketching interpretation in novice and expert designers
source	Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 209-220
summary	This paper focuses on the differences in visual reasoning between a novice and an expert architectural designer during the conceptual design process. The cognitive actions of each designer while sketching were categorized into four main groups (each consisting of a number of sub-groups): physical, perceptual, functional, and conceptual. Based on this analysis, we found that the expert differs markedly from the novice in productivity in terms of the number of sketches and the number of alternative ideas. We focused on the differences between them in terms of the frequencies of cognitive actions, with the hypothesis that the difference in productivity could be attributed to the differences in some or all types of cognitive actions. Differences between the expert and the novice were found for revising features (in the subcategory of drawing actions in the physical action category), for paying attention to the relations of depicted elements (perceptual category) and for the rates of new and revisited functions (functional category). These results are discussed in terms of the types of visual reasoning processes that could be involved in expert design and the possible implications of these results if they can be demonstrated to be characteristic of expert designers generally.

title	Computer in Creation of Architectural Form
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999,pp. 131-142
summary	This paper considers graphic methods of presentation of ideas 'in the creation of architectural forms' and evolution of these methods, determined by the implementations of information technology. Drawings have been the main medium of expression since Leonardo da Vinci to the present-day. Graphic communication has always been treated as a main design tool, both - at the ending stage of design and at the early design stage. Implementation of computers in design doe not change this situation. The entire design process proceeds in a traditional way. While searching for the idea we use hand sketches and, after this, technical drawings are draught on a plotter, which replaces a drawing pen. Using computers at the early design stages encounters serious difficulties. The main thesis of this paper is that hardware and software inadequacy is not the problem, the problem is in the inadequacy of the design methods. This problem is to be reconceived as what a person can do with a program, rather than what is the capacity of a program. Contemporary computer techniques allow us to put an equation mark between the searching for idea, visualisation and its realisation in virtual space. This paper presents Sketching by scanning - an experimental method of using computer hardware and software for stimulating of searching of architectural's form.

title	What's Real About Virtual Reality
source	IEEE Computer Graphics and Applications, Vol. 19, no. 6, Nov/Dec, 27
summary	As is usual with infant technologies, the realization of the early dreams for VR and harnessing it to real work has taken longer than the wild hype predicted, but it is now happening. I assess the current state of the art, addressing the perennial questions of technology and applications. By 1994, one could honestly say that VR "almost works." Many workers at many centers could doe quite exciting demos. Nevertheless, the enabling technologies had limitations that seriously impeded building VR systems for any real work except entertainment and vehicle simulators. Some of the worst problems were end-to-end system latencies, low-resolution head-mounted displays, limited tracker range and accuracy, and costs. The technologies have made great strides. Today one can get satisfying VR experiences with commercial off-the-shelf equipment. Moreover, technical advances have been accompanied by dropping costs, so it is both technically and economically feasible to do significant application. VR really works. That is not to say that all the technological problems and limitations have been solved. VR technology today "barely works." Nevertheless, coming over the mountain pass from "almost works" to "barely works" is a major transition for the discipline. I have sought out applications that are now in daily productive use, in order to find out exactly what is real. Separating these from prototype systems and feasibility demos is not always easy. People doing daily production applications have been forthcoming about lessons learned and surprises encountered. As one would expect, the initial production applications are those offering high value over alternate approaches. These applications fall into a few classes. I estimate that there are about a hundred installations in daily productive use worldwide.

title	Architectural Computing from Turing to 2000 [Conference Proceedings]
doi	https://doi.org/10.52842/conf.ecaade.1999
source	eCAADe Conference Proceedings / ISBN 0-9523687-5-7 / Liverpool (UK) 15-17 September 1999, 773 p.
summary	The core theme of this book is the idea of looking forward to where research and development in Computer Aided Architectural Design might be heading. The contention is that we can do so most effectively by using the developments that have taken place over the past three or four decades in Computing and Architectural Computing as our reference point; the past informing the future. The genesis of this theme is the fact that a new millennium is about to arrive. If we are ruthlessly objective the year 2000 holds no more significance than any other year; perhaps we should, instead, be preparing for the year 2048 (2k). In fact, whatever the justification, it is now timely to review where we stand in terms of the development of Architectural Computing. This book aims to do that. It is salutary to look back at what writers and researchers have said in the past about where they thought that the developments in computing were taking us. One of the common themes picked up in the sections of this book is the developments that have been spawned by the global linkup that the worldwide web offers us. In the past decade the scale and application of this new medium of communication has grown at a remarkable rate. There are few technological developments that have become so ubiquitous, so quickly. As a consequence there are particular sections in this book on Communication and the Virtual Design Studio which reflect the prominence of this new area, but examples of its application are scattered throughout the book. In 'Computer-Aided Architectural Design' (1977), Bill Mitchell did suggest that computer network accessibility from expensive centralised locations to affordable common, decentralised computing facilities would become more commonplace. But most pundits have been taken by surprise by just how powerful the explosive cocktail of networks, email and hypertext has proven to be. Each of the ingredients is interesting in its own right but together they have presented us with genuinely new ways of working. Perhaps, with foresight we can see what the next new explosive cocktail might be.

title	Digital Sensations: Space, Identity, and Embodiment in Virtual Reality
source	University of Minnesota Press, Minneapolis, Minnesota
summary	Virtual reality is in the news and in the movies, on TV and in the air. Why is the technology -- or the idea -- so prevalent precisely now? What does it mean -- what does it do -- to us? Digital Sensations looks closely at the ways representational forms generated by communication technologies -- especially digital/optical virtual technologies -- affect the "lived" world. Virtual reality, or VR, is a technological reproduction of the process of perceiving the real; yet that process is "filtered" through the social realities and embedded cultural assumptions about human bodies, perception, and space held by the technology's creators. Through critical histories of the technology -- of vision, light, space, and embodiment -- Ken Hillis traces the various and often contradictory intellectual and metaphysical impulses behind the Western transcendental wish to achieve an ever more perfect copy of the real. Because virtual technologies are new, these histories also address the often unintended and underconsidered consequences -- such as alienating new forms of surveillance and commodification -- flowing from their rapid dissemination. Current and proposed virtual technologies reflect a Western desire to escape the body Hillis says. Exploring topics from VR and other, earlier visual technologies, Hillis's penetrating perspective on the cultural power of place and space broadens our view of the interplay between social relations and technology.

title	The Future of CAAD: From Computer-Aided Design to Computer-Aided Collaboration
source	Llavaneras S., Gustavo J. and Negrón P., Enssa (eds.), 1ra Conferencia Venezolana sobre Aplicación de Computadores en Arquitectura, Caracas (Venezuela) 1-3 december 1999, pp. 19-28
summary	The primary uses of computers in the construction industry have been shifting, over the past four decades, from the evaluation of proposed design solutions, to their graphical (and other) representation, and more recently to facilitating collaboration among the various professionals who are involved in the design process. This paper argues that what may appear to be shifts in emphasis actually represents convergence on a single, original goal: the use of computers to help designers (and others who are involved in the design decision making process) to assess the quality, desirability, and the implications of their creations. Such assistance requires representation, communication, and analysis. The paper goes on to show how these individual parts can be joined into an integrated collaborative design environment, where they build upon and strengthen each other. Moreover, the paper argues that this convergence represents the future of CAAD research and development.

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".

summary	In this paper we adopt the approach that designing is a series of situated acts, ie designing cannot be pre-planned to completion. This is based on ideas from situated cognition theory that claims that what people perceive, how they conceive and what they do develop together and are adapted to the environment. For a system to be useful for human designers it must have the ability to associate what is learned to its environment. In order for a system to do that such a system must be able to acquire knowledge of the environment that a design constructs. Therefore, acknowledging the notion of situatedness is of importance to provide a system with such capability and add on a new dimension to existing learning systems in design. We will call such a learning system within the design domain a Situated Learning Design System (SLDS). A SLDS should be able to create its own situational categories from its perceptual experiences and modify them if encountered again to link the learned knowledge to its corresponding situation. We have chosen architectural shapes as the vehicle to demonstrate our ideas and used multiple representations to build a platform for a SLDS to learn from. In this paper the notion of situatedness and its role in both designing and learning is discussed. The overall architecture of a SLDS is introduced and how the potential outcome of such a system will support human designers while designing is discussed.

summary	The history of CAAD research is largely one of generic computing techniques grafted on to existing design practices. The motivation behind such research, on different occasions, has been to automate some or all of the design process, to provide design assistance, to check designs for compliance against some predefined criteria, or more recently to enable people to experience designs as realistically as possible before they are built. But these goals remain unexamined, and their fulfilment is assumed to be a self-evident benefit. In the worst cases, they are examples of barely concealed technology-push. Few researchers have stated in detail what they want computers to do for architectural design, most choosing instead to focus on what computers can do, rather than what is needed. This paper considers what we want CAAD systems to do for us. However, this will be a modest effort, a beginning, a mere sketch of possible directions for CAAD. But it should open channels for criticism and serious debate about the role of CAAD in the changing professional, social and cultural contexts of its eventual use in education and practice. The paper, therefore, is not so concerned to arrive at a single 'right' vision for future CAAD systems as concerned by the lack of any cogent vision for CAAD.

title	Modelling architectural design information by features : an approach to dynamic product modelling for application in architectural design
source	Eindhoven University of Technology
summary	Architectural design, like many other human activities, benefits more and more from the ongoing development of information and communication technologies. The traditional paper documents for the representation and communication of design are now replaced by digital media. CAD systems have replaced the drawing board and knowledge systems are used to integrate expert knowledge in the design process. Product modelling is one of the most promising approaches in the developments of the last two decades, aiming in the architectural context at the representation and communication of the information related to a building in all its aspects and during its complete life-cycle. However, after studying both the characteristics of the product modelling approach and the characteristics of architectural design, it is concluded in this research project that product modelling does not suffice for support of architectural design. Architectural design is characterised mainly as a problem solving process, involving illdefined problems that require a very dynamic way of dealing with information that concerns both the problem and emerging solutions. Furthermore, architectural design is in many ways an evolutionary process. In short term this is because of the incremental approach to problem solving in design projects; and in long term because of the stylistic development of designers and the continuous developments in the building and construction industry in general. The requirements that are posed by architectural design are concentrated in the keywords extensibility and flexibility of the design informationmodels. Extensibility means that designers can extend conceptual models with definitions that best suit the design concepts they wish to utilise. Flexibility means that information in design models can be structured in a way that accurately represents the design rationale. This includes the modelling of incidental characteristics and relationships of the entities in the model that are not necessarily predefined in a conceptual model. In general, product modelling does not adequately support this dynamic nature of design. Therefore, this research project has studied the concepts developed in the technology of Feature-based modelling, which originates from the area of mechanical engineering. These concepts include the usage of Features as the primitives for defining and reasoning about a product. Features have an autonomous function in the information model, which, as a result, constitutes a flexible network of relationships between Features that are established during the design process. The definition of Features can be specified by designers to formalise new design concepts. This allows the design tools to be adapted to the specific needs of the individual designer, enlarging the library of available resources for design. In addition to these key-concepts in Feature-based modelling as it is developed in the mechanical engineering context, the project has determined the following principles for a Feature-based approach in the architectural context. Features in mechanical engineering are used mainly to describe the lowest level of detail in a product's design, namely the characteristics of its parts. In architecture the design process does not normally follow a strictly hierarchical approach and therefore requires that the building be modelled as a whole. This implies that multiple levels of abstraction are modelled and that Features are used to describe information at the various abstraction levels. Furthermore, architectural design involves concepts that are non-physical as well as physical; Features are to be used for modelling both kinds. The term Feature is defined in this research project to reflect the above key-concepts for this modelling approach. A Feature is an autonomous, coherent collection of information, with semantic meaning to a designer and possibly emerging during design, that is defined to formalise a design concept at any level of abstraction, either physical or non-physical, as part of a building model. Feature models are built up entirely of Features and are structured in the form of a directed graph. The nodes in the graph are the Features, whereas the arcs are the relationships between the Features. Features can be of user-defined types and incidental relationships can be added that are not defined at the typological level. An inventory in this project of what kind of information is involved in the practice of modelling architectural design is based on the analysis of a selection of sources of architectural design information. This inventory is deepened by a case study and results in the proposition of a categorisation of architectural Feature types.

title	Digitally Mediated Design: Using Computer Programming to Develop a Personal Design Process
source	Massachusetts Institute of Technology, Department of Architecture
summary	This thesis is based on the proposal that the current system of architectural design education confuses product and process. Students are assessed through, and therefore concentrate on, the former whilst the latter is left in many cases to chance. This thesis describes a new course taught by the author at MIT for the last three years whose aim is to teach the design process away from the complexities inherent in the studio system. This course draws a parallel between the design process and the Constructionist view of learning, and asserts that the design process is a constant learning activity. Therefore, learning about the design process necessarily involves learning the cognitive skills of this theoretical approach to education. These include concrete thinking and the creation of external artifacts to develop of ideas through iterative, experimental, incremental exploration. The course mimics the Constructionist model of using the computer programming environment LOGO to teach mathematics. It uses computer programming in a CAD environment, and specifically the development of a generative system, to teach the design process. The efficacy of such an approach to architectural design education has been studied using methodologies from educational research. The research design used an emergent qualitative model, employing Maykut and Morehouses interpretive descriptive approach (Maykut & Morehouse, 1994) and Glaser and Strausss Constant Comparative Method of data analysis (Glaser & Strauss, 1967). Six students joined the course in the Spring 1999 semester. The experience of these students, what and how they learned, and whether this understanding was transferred to other areas of their educational process, were studied. The findings demonstrated that computer programming in a particular pedagogical framework, can help transform the way in which students understand the process of designing. The following changes were observed in the students during the course of the year: Development of understanding of a personalized design process; move from using computer programming to solve quantifiable problems to using it to support qualitative design decisions; change in understanding of the paradigm for computers in the design process; awareness of the importance of intrapersonal and interpersonal communication skills; change in expectations of, their sense of control over, and appropriation of, the computer in the design process; evidence of transference of cognitive skills; change from a Behaviourist to a Constructionist model of learning Thesis Supervisor: William J.

summary	Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

title	Where the Footprints Lead: Tracking down other roles for social navigation
source	Social Navigation of Information Space, eds. A. Munro, K. H. and D Benyon. London: Springer-Verlag, pp 15-34
summary	Collaborative Filtering was proposed in the early 1990's as a means of managing access to large information spaces by capturing and exploiting aspects of the experiences of previous users of the same information. Social navigation is a more general form of this style of interaction, and with the widening scope of the Internet as an information provider, systems of this sort have rapidly moved from early research prototypes to deployed services in everyday use. On the other hand, to most of the HCI community, the term social navigation" is largely synonymous with "recommendation systems": systems that match your interests to those of others and, on that basis, provide recommendations about such things as music, books, articles and films that you might enjoy. The challenge for social navigation, as an area of research and development endeavour, is to move beyond this rather limited view of the role of social navigation; and to do this, we must try to take a broader view of both our remit and our opportunities. This chapter will revisit the original motivations, and chart something of the path that recent developments have taken. Based on reflections on the original concerns that motivated research into social navigation, it will explore some new avenues of research. In particular, it will focus on two. The first is social navigation within the framework of "awareness" provisions in collaborative systems generally; and the second is the relationship of social navigation systems to spatial models and the ideas of "space" and "place" in collaborative settings. By exploring these two ideas, two related goals can be achieved. The first is to draw attention to ways in which current research into social navigation can be made relevant to other areas of research endeavour; and the second is to re-motivate the idea of "social navigation" as a fundamental model for collaboration in information-seeking."
