summary The VR-DIS project aims to provide design support in the early design stage using a Virtual Reality environment. The initial brief of the design system is based on an analysis of a design case. The paper describes the process of analysis and extraction of design knowledge and design concepts in terms of Features. It is demonstrated how the analysis has lead to a classification of design concepts. This classification forms one of the main specifications for the VR-based design aid system that is being developed in the VR-DIS programme. The paper concludes by discussing the particular approach used in the case analysis and discusses future work in the VR-DIS research programme.

summary In Winter/Spring 1999, DYNAMO - a Web-based design assistant for student architects - received its baptism of fire in a 4th year design studio at our department. The paper describes the setting and procedure of the baptism, the participation of the studio teaching staff, and the students' reactions and appreciation. Based on students' responses to a questionnaire and observations of the tool in use, we investigated whether DYNAMO succeeded in engaging students and what factors stimulated/hampered this engagement. Although students were noticeably enthusiastic about the tool, three factors revealed themselves as major obstacles to student engagement: lack of time, of encouragement by the teachers and of studio equipment. The paper concludes with lessons learned for the future of DYNAMO and, more in general, of ICT in education.

summary The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

summary This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

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 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.

We give a speci cation of a new sys- tem, in which we strive for a more natural and intuitive interaction. A key element is geometric analysis. From the input of the user, implicit geo- metric and structural relations are derived, which are used during subsequent interaction.

title THE EXPERIENCE OF SPACE IN FULL-SCALE MODELS AND VIRTUAL REALITY
source Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 67-74
summary Do we experience the size and character of virtual spaces in the same way as real spaces? What impact has the meaning of a space, i.e. furniture and other clues to the use of a space, on our experience of it? This paper describes an experiment where the participants could navigate through a room, first on desktop-VR, then in full-scale VR (in a CAVE) and finally in a full-scale model. In a first phase the room was empty and only defined through walls, windows and doors. Later on furniture was added as well as colors and textures. The experiment was a pilot study and threw light on some questions which we intend to develop in further investigations. It showed that the participants used building components like doors and windows and furniture in the presentation on desktop VR for their estimation of the size of the room. In the CAVE and in the full-scale model the participants' bodies were the measure for their estimations. The experiment also hinted at that color and texture had an impact on the experience of size.

summary In January 1998, the Montana State University School of Architecture embarked upon an initiative to successfully integrate computer technology into its design curriculum. At that time only a handful of student computers could be found in the design studio. By January 1999 over 95 students have and use computers in their courses. The increase in computer access and use is occurring through a five-phase initiative called the Universal Lab-a school-wide commitment to the full integration of computer technology into all design studios, support courses and architectural electives. The Universal Lab uses the areas of Access, Instruction and Application as the vehicles for appropriate placement and usage of digital concepts within the curriculum. The three-pronged approach allows each instructor to integrate technology using one, two or all three areas with varying degrees of intensity. This paper presents the current status of the Universal Lab-Phase I and Phase II-and describes the effect of this program on student work, course design and faculty instruction.

summary In the early 1990s, the introduction of an extensive CAAD component in the compulsory curriculum of the Faculty of Architecture, Delft University of Technology, stimulated experimentation with computer-based instruction systems. The emergence of the World Wide Web presented new possibilities. Nevertheless, the reasons for investing in Web-based CAAD instruction were mostly pragmatic, i.e. a reaction to necessity, rather than an intention to explore, experiment and revolutionize. One of the problems addressed in our Web-based CAAD instruction is CAAD literacy. Help files and manuals that accompany software have proven to be unsuitable for introductory courses in design computing. This led to the development of a series of dynamic Web-based tutorials, in the form of interactive slide shows. The implementation of the tutorials is based on a cooperative framework that allows teachers and students to contribute at different levels of technical and methodical complexity. The use of the Web in CAAD education also stimulated a more active attitude among students. Despite the limited support and incentives offered by the Faculty, the Web-based CAAD courses became an invitation to intelligent and meaningful use of Web technologies by students for design presentation and communication. This is not only a useful addition to the opportunities offered by CAAD systems but also a prerequisite to new design communities.

summary A few years ago I began to investigate the concepts of art-to-part and single part custom manufacturing. The original designs had to created on a CAD system either manually or by algorithm and then machine produced without any manual intervention. Rapid prototyping and laser cutting technology were both reviewed and the later selected for possible use. I also had a long time interest in geometric design. At that time one of my CAD classes took some of there window designs, created from a complex series of overlapping circles, arcs, and splines, and had them laser cut. The results were astonishing.

summary The dogmatic structure of architectural education has meant that the production and application of new educational theories, leading to educational models that use computer technology as their central medium of education, is still a relatively under-explored area. Partial models cannot deliver the expected bigger steps, but only bits and pieces. Curricula developments, at many schools of architecture, have been carried out within the closed circuit manner of architectural education, through expanding the traditional curricula and integrating computers into them. There is still no agreed curriculum in schools of architecture, which defines, at least conceptually, the use of computers within it. Do we really know what we are doing? In the words of Aart Bijl; 'If I want to know what I am doing, I need a separate description of my doing it, a theory' [Bijl, 1989]. The word 'sustainability' is defined as understanding the past and responding to the present with concern for the future. Applying this definition to architectural education, this paper aims to outline the necessity and the principles for the construction of a theory of a sustainable computer aided architectural education model, which could lead to an architectural education that is lasting.

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 The art of growth and the solution of cognitive problems
source International Conference on Generative Art
summary A cellular method is proposed as an alternative for a connectionist approach. The present method does not use connections between cells, but introduces a field concept instead. If the fields are determined in accordance with the transformations familiar from fractal theory, then the solutions of problems that have some symmetry are forms of remarkable beauty. This way, a link is proposed between generative art and problem solving. It is conjectured that the ‘black box’ nature of connectionist systems can be replaced by an approach in which the solution of a problem coincides with a vivid visualization, also if the problems at hand are of a high-dimensional nature.

title Self-Selecting Digital Design Students

doi https://doi.org/10.52842/conf.ecaade.2000.085
summary Recent years have seen the increasing use of digital media in undergraduate architectural education at UND, and which has been fuelled by students themselves taking up the tools available to practising architects. This process of self-selection may hold valuable lessons for the development of architectural curricula. An experimental design studio offered as an elective to UND undergraduates in 1999 has indicated that the design work produced therein, most often differed remarkably from the previous work of the same students using only traditional media. In so far as digital environments rapidly provide new and strange objects and images for students to encounter, those students are driven to interpret, transform or customise that environment in innovative ways, thereby making it their own. It is clear that the full integration of digital environments into architectural education will profoundly effect the outcomes of student work. We have observed that some self-selecting students struggle in expressing ideas through repre-sentative form in traditional studios. The question arises whether these students are "onto something" which they intuitively understand as better suited to their abilities, or whether in fact they are see digital tools as a means to avoid those areas in design in which they experience difficulties. Through observation of a group of "self-selectors" the authors attempt to lead useful generalisations; to develop a theory and method for facilitators to deal with specific students; and to work toward the development of suitable curricula for these cases.

title Toolspaces and Glances: Storing, Accessing, and Retrieving Objects in 3D Desktop Applications
source Proceedings of the Symposium on Interactive 3D Graphics 1999. pp. 163-168
summary Users of 3D desktop applications perform tasks that require accessing data storage, moving objects, and navigation. These operations are typically performed using 2D GUI elements or 3D widgets. We wish to focus on interaction with 3D widgets directly in the 3D world, rather than forcing our users to repeatedly switch contexts between 2D and 3D. However, the use of 3D widgets requires a mechanism for storing, accessing, and retrieving these widgets. In this paper we present toolspaces and glances to provide this capability for 3D widgets and other objects in interactive 3D worlds. Toolspaces are storage spaces attached to the user's virtual body; objects placed in these spaces are always accessible yet out of the user's view until needed. Users access these toolspaces to store and retrieve objects through a type of lightweight and ephemeral navigation we call glances.

title Design Gaming, Designing Games - Learning Design through Game Playing and Game Making
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 28-33
doi https://doi.org/10.52842/conf.ecaade.2002.028
summary This is an ongoing effort to make design learning fun and constructive. The process of designing, in many respects, is very similar to playing games: exploring possibilities under certain constraints. Since 1999, the “designing as game playing” concept has been used in architectural design studios and related courses in my institution. In the early years, preexisting games or games created by instructors were used. These games were played in a junior-year course that emphasized design decision-making and design collaborations. In recent two years, design game making has been used as a vehicle for senior-year student to strengthen their analytical skills. So far, students have developed games of Mario Botta, Le Corbusier (Villa Savoy), Aldolf Loos, Mies van der Rohe, and Richard Meier. Two more games are underdevelopment: the games of Isosaki and Tadao Ando. Some of these games have been used in freshman-year courses to introduce certain principles of form composition. Playing design games enables students to gain design knowledge as well as to be able to view design constraints constructively as special characteristics on the game board that may turn to their advantages rather than as useless stumbling blocks. Designing games requires students to analyze existing designs in great details as well as to be able to organize certain relationships of these details into operable rules that could produce new designs. The experience of teaching “games and design” to-date has been a very fruitful one. Future work will focus on design gaming for freshman students and game designing for senior students, as well as the interaction between the freshmen (game players) and the seniors (game designers).

summary New media have been successfully taken up in music, films, car design, fashion, magazine and book publishing, the sex industry, and education. Only architecture and urban design are slow to incorporate new media technologies. To some extent, architecture and mediation are locked into a conflicting, for the most part mutually excluding, relationship. At first sight this looks logical; architecture is a place, a real, once-only place, which you experience by visiting it. You do not experience architecture through dissolving a building and electronically replicating it a billion times in the air. But all technology is social before it becomes a technique; the technology of mediation needs to be more deeply incorporated within the practice of architecture, and to be more widely understood and supported before it can be fully exploited as a tool. This process is just beginning; as yet there is no fully evolved ideological scope which incorporates the new mediated position as an essential part of architecture. New mediation technologies have taken over some of the functions of buildings, such as security, surveillance, and communication with the outside, but these are not the most relevant aspects for the practice of architecture itself.

summary After having had students in practical training for some years now, both in Belgium and in other European countries, we have discovered it does not really matter which CAD package is used in the design office they work in. Having an AutoCAD background means that most of the time it is only a matter of hours for one to be able to work with almost every other CAD program. Even better; within weeks quite a number of our students actually became responsible for the CAD-department in the office.
