summary	CADET, CAD education and training, a research unit with the Department of Architecture and Building Science (Faculty of Engineering, University of Strathclyde) promotes an integrated approach to the built environment, seeking to bring together the rational and expressive modes of thought by teaching design through IT and CAD. In recent years this has been introduced as a pilot project within the primary and secondary school sector as well as Year 1 and Year 2 of the Building Design Engineering (BDE). The presentations discussed in this paper demonstrate recent projects in a social context - modelling possible spaces via virtual reality on behalf of clients in education and social work environments. The motivation for such a creative and participatory dialogue in a community context acknowledges that, in the wake of post industrialisation, the reconstruction of our urban environments demands that we develop the tools required for a meaningful participation in the design process. The nature of a participatory process demands a demystification of the design process, which is a reality made possible by CAD.

summary	The Bartlett School of Graduate Studies, University College London (UCL), set up the first MSc in Virtual Environments in the UK in 1995. The course aims to synthesise and build on research work undertaken in the arts, architecture, computing and biological sciences in exploring the realms of the creation of digital and virtual immersive spaces. The MSc is concerned primarily with equipping students from design backgrounds with the skills, techniques and theories necessary in the production of virtual environments. The course examines both virtual worlds as prototypes for real urban or built form and, over the last few years, has also developed an increasing interest in the the practice of architecture in purely virtual contexts. The MSc course is embedded in the UK government sponsored Virtual Reality Centre for the Built Environment which is hosted by the Bartlett School of Architecture. This centre involves the UCL departments of architecture, computer science and geography and includes industrial partners from a number of areas concerned with the built environment including architectural practice, surveying and estate management as well as some software companies and the telecoms industry. The first cohort of students graduated in 1997 and predominantly found work in companies working in the new market area of digital media. This paper aims to outline the nature of the course as it stands, examines the new and ever increasing market for designers within digital media and proposes possible future directions for the course.

title	Enseñanza de la representación manual y digital, para arquitectos y diseñadores [Teaching Hand and Digital Representation to Architects and Designers]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The supremacy of the digital means of representation and communication and the resulting shift of the manual means in the field of design and architecture, have engendered multiple opinions and literature. They focus and analyze the virtues and risks, the losses and substitutions, and the different expressive, productive and conceptual results of their leading role in the creative process. Furthermore, if we consider both as two extremes, apparently opposed, a broad panorama of combinations and additions are produced by the emerging group of hybrid practices. This motivated the development of a research project in the Universidad Nacional del Litoral de Santa Fe, Argentina, under the Program CAI+D 2000 dealing with Design and the Analog – Digital Means. From this project emerged a collection of conceptual speculations and experimentations in the extended field of representation, extended by the incorporation of new means and hybridations, searching for new parameters and methods for professional training and practice. Key words: analog, digital, graphics, means, representation.

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title	Redirecting design generation in architecture
source	International Conference on Generative Art
summary	Design generation has been the traditional culmination of computational design theory in architecture. Motivated either by programmatic and functional complexity (as in space allocation) or by the elegance and power of representational analyses (shape grammars, rectangular arrangements), research has produced generative systems capable of producing new designs that satisfied certain conditions or of reproducing exhaustively entire classes (such as all possible Palladian villas), comprising known and plausible new designs. Most generative systems aimed at a complete spatial design (detailing being an unpopular subject), with minimal if any intervention by the human user / designer. The reason for doing so was either to give a demonstration of the elegance, power and completeness of a system or simply that the replacement of the designer with the computer was the fundamental purpose of the system. In other words, the problem was deemed either already resolved by the generative system or too complex for the human designer. The ongoing democratization of the computer stimulates reconsideration of the principles underlying existing design generation in architecture. While the domain analysis upon which most systems are based is insightful and interesting, jumping to a generative conclusion was almost always based on a very sketchy understanding of human creativity and of the computer's role in designing and creativity. Our current perception of such matters suggests a different approach, based on the augmentation of intuitive creative capabilities with computational extensions. The paper proposes that architectural generative design systems can be redirected towards design exploration, including the development of alternatives and variations. Human designers are known to follow inconsistent strategies when confronted with conflicts in their designs. These strategies are not made more consistent by the emerging forms of design analysis. The use of analytical means such as simulation, couple to the necessity of considering a rapidly growing number of aspects, means that the designer is confronted with huge amounts of information that have to be processed and integrated in the design. Generative design exploration that can combine the analysis results in directed and responsive redesigning seems an effective method for the early stages of the design process, as well as for partial (local) problems in later stages. The transformation of generative systems into feedback support and background assistance for the human designer presupposes re-orientation of design generation with respect to the issues of local intelligence and autonomy. Design generation has made extensive use of local intelligence but has always kept it subservient to global schemes that tended to be holistic, rigid or deterministic. The acceptance of local conditions as largely independent structures (local coordinating devices) affords a more flexible attitude that permits not only the emergence of internal conflicts but also the resolution of such conflicts in a transparent manner. The resulting autonomy of local coordinating devices can be expanded to practically all aspects and abstraction levels. The ability to have intelligent behaviour built in components of the design representation, as well as in the spatial and building elements they signify, means that we can create the new, sharper tools required by the complexity resulting from the interpretation of the built environment as a dynamic configuration of co-operating yet autonomous parts that have to be considered independently and in conjunction with each other. P.S. The content of the paper will be illustrated by a couple of computer programs that demonstrate the princples of local intelligence and autonomy in redesigning. It is possible that these programs could be presented as independent interactive exhibits but it all depends upon the time we can make free for the development of self-sufficient, self-running demonstrations until December.

title	Computational Sketch Analyser (CSA): Extending the Boundaries of Knowledge in CAAD
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 503-510
doi	https://doi.org/10.52842/conf.ecaade.1999.503
summary	This paper focuses on the cognitive problem-solving strategies of professional architectural designers and their use of external representations for the production of creative ideas. Using a new form of protocol analysis (Computational Sketch Analysis), the research has analysed five architects' verbal descriptions of their cognitive reasoning strategies during conceptual designing. It compares these descriptions to a computational analysis of the architects' sketches and sketching behaviour. The paper describes how the current research is establishing a comprehensive understanding of the mapping between conceptualisation, cognition, drawing, and complex problem solving. The paper proposes a new direction for Computer Aided Architectural Design tools (CAAD). It suggests that in order to extend the boundaries of knowledge in CAAD an understanding of the complex nature of architectural conceptual problem-solving needs to be incorporated into and supported by future conceptual design tools.

title	The Slow Rise of 3D on the Web
source	Computer Graphics Worlds - July 2001, p. 22
summary	Consumer, commercial, and educational applications on the Web have been slow to take advantage of 3D, although for years it has been viewed as a boon for the graphics industry. Over the last 18 months, the situation has begun to look more favorable for the graphics industry, reports M2 Research's Wanda Meloni. Meloni says changes in the market and in technology have fueled the rise of 3D on the Web. The increase in broadband connections from 2.7 million users in 1999 to 8 million users in 2000 means that the market of consumers who have Internet connections fast enough to view and interact with 3D content has grown considerably. Also, 3D players are no longer limited to a proprietary format now that new game consoles from Nintendo and Microsoft will offer Web-based real-time 3D multiplayer gaming; in addition, 3D graphics technology will now be embedded into applications for Internet appliances and handheld devices. M2 Research estimates that the number of Web media players that are 3D-enabled will rise from 17 percent currently to 32 percent by the end of the year, as 3D player vendors offer more direct support to 2D players such as RealPlayer and Shockwave. Still, content production will remain a major hurdle because millions of Web authors are not using 3D. Meloni says creative professionals and digital designers will need a new set of 3D tools that will work seamlessly with current Web content in video, 2D graphics, and audio.

It is not the subject of a major dot.com ad campaign. Instead, it gets away from mass marketing to offer a vehicle for profound creative expressions. It brings designers together, generates ideas, asks questions, discusses philosophies, and leaves marks as if inevitable forces of nature caused it.

title	Design computing: A new challenge for creative synergy
source	In Saito, N. (Ed.), Creative digital media: Its impact on the new century (pp. 132-136), Japan: Keio University Press
summary	As content becomes increasingly significant in giving ‘face’ to information technology (IT), the need to train and produce content designers has also become more and more important. The development of powerful computer technologies and the complexity of design have demanded designers to re-examine the design process and consider the adaptation of tools that will provide for creativity, improve the overall design process and, at the same time, reveal new insights (Rafi and Karboulonis, 2000). This paper gives an overview of the relationship between art and science through the ages, and discusses their relatively recent re-convergence. This text further argues that a re-convergence between art and science is currently occurring, highlighting the need to accelerate the process. It is suggested that re-convergence is a result of new technologies being researched, namely related to effective visualisation and communication of ideas and concepts, subsequently adopted by practitioners. Such elements, with tools that offer increased power and new abilities, are widely found today in the multimedia and the Virtual Environment (VE) as scientists and designers venture into each other’s domain. This paper also argues that content designers of the future must not only be both artist and technologist, but artist and technologist that are aware of the context in which content is being developed. The presentation will be a showcase of our exploration at the Faculty of Creative Multimedia, Multimedia University for the last 4 years, in integrating design and computer skills – the synergy that we called DESIGN COMPUTING.

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	Hearing Architectural Design: Simulation and Auralization for Generating Better Acoustic Spaces
source	International Conference on Generative Art
summary	This paper with demonstration is devoted to revealing and establishing the relationship between space and sound through computational acoustic analysis, simulation and electronic synthesis of audible sound. Based on science of acoustics and computing technology, acoustic effect of an architectural 3-D design can be analyzed and the resulted sound in space can be synthesized and predicted accordingly and being heard. Auralization refers to this process of acoustic analysis, sound synthesis and audio presentation of the result in the form of audible sound. Design alternatives can be experimented until satisfactory acoustic effect is achieved. Traditionally, designers rely on some minimum and vague understanding or specialists’ experiences to predict and design for a desirable sound behavior in spaces. Most likely acoustic design and analysis are seen as a luxury remedy only affordable in large-scale theatres and concert halls. The recent available PC based auralization tools brought significance in both in terms of new knowledge towards the science and art of architectural acoustics and the methods and practice in the design process. The examples demonstrated in the presentation will indicate that the auralization technology make it possible for the designers, consultants, end users or potential occupants to examine and evaluate the performance of different designs by hearing it directly before an informed decision can be made. The case studies also illustrated that the auralization is a powerful tool for general public with common building types to uncover everyday acoustic problems that have been constantly harming their well being and would otherwise be undetected.

summary	San Juan city was almost completely destroyed by an earthquake in 1944. The present work intends to show a series of readings about urban space of the pre 44 city. Our purpose is to find out the variation of its qualities at different levels of formatization of the spaces; and the tales of constants that could be operating in the symbolic construction of the city, by the inhabitant’s mental representations. To describe the missing city, to rebuild it as a digital patrimony in order to understand its identity features, means to search for into its history , qualities and uses of its places and shapes. With a new video which resumes the results of the digital reconstruction of the city, the present research intends to share our questions about the ruptures and mutations at the urban level in order to build a possible answer from the urban virtuality.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	Playing with design intents: integrating physical and urban constraints in CAD
source	Automation in Construction 9 (1) (2000) pp. 93-105
summary	Our work deals with the exploration of a universe of forms that satisfy some design intents. That is, we substitute a "generate and test" approach for a declarative approach in which an object is created from its properties. In this paper we present an original method that takes into account design intents relative to sunlight, visibility and urban regulation. First of all we study how current CAD tools have considered these properties until now. Our conclusion is that the classical design/simulation/analysis process does not suit design practices, especially in the early stages. We think that an improved CAD system should offer the architect the option of manipulating abstract information such as design intents. We define an intent as a conceptual expression of constraints having an influence on the project. For instance, a visual intent will be stated with no reference to vision geometry: "from this place, I want to see the front of the new building". We show how to represent each of these constraints with a 3D volume associated to some characteristics. If some solutions exist, we are sure that they are included in these volumes. For physical phenomena we compute the volume geometry using the principles of inverse simulation. In the case of urban regulation we apply deduction rules. Design intents are solved by means of geometrical entities that represent openings or obstructions in the project. Computing constraint volumes is a way of guiding the architect in his exploration of solutions. Constraint volumes are new spaces that can restore the link between form and phenomenon in a CAD tool. Our approach offers the designer the possibility of manipulating design intents.

title	Computer-aided design systems for the 21st century: some design guidelines
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper proposes nine design principles for a new generation of computer-aided design (CAD) systems that actively support the decision making and problem solving activities of environmental design. Foremost among these are: a meaningful internal object-based representation of the artifact being designed within its environmental context; a collaborative problem solving paradigm in which the human designer and the computer form a complementary partnership; and, the notion of decision-support tools rather than predefined solutions. Two prototype computer-aided design systems implemented by the CAD Research Center that embody most of these concepts are described. ICADS (Intelligent Computer-Aided Design System) incorporates multiple expert agents in domains such as natural and artificial lighting, noise control, structural system selection, climatic determinants, and energy conservation. Given a particular building design context, the agents in ICADS draw upon their own expertise and several knowledgebases as they monitor the actions of the human designer and collaborate opportunistically. KOALA (Knowledge-Based Object-Agent Collaboration) builds on the multi-agent concepts embodied in ICADS by the addition of two kinds of agents. Mentor agents represent the interests of selected objects within the ontology of the design environment. In the implemented KOALA system building spaces are represented by agents capable of collaborating with each other, with domain agents for the provision of expert services, and with the human designer. Facilitator agents listen in on the communications among mentor agents to detect conflicts and moderate arguments. While both of these prototype systems are limited in scope by focussing on the earliest design stages and restricted in their understanding of the inherent complexity of a design state, they nevertheless promise a paradigm shift in computer-aided design.

title	Recognition of spatial grouping in rectangular arrangements
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Rectangular arrangements are an efficient technique for generating an exhaustive catalogue of a class of designs. Moreover, they offer the possibility of retrieving designs from such a catalogue on the basis of geometric or topological features. The paper describes an extension of the possibilities of rectangular arrangements in indexing and retrieving catalogues of architectural floor plans through the recognition of spatial grouping. Using an adaptation of the chain code, each space in a shape arrangement is labeled in terms of its bilateral geometric relationships with contiguous spaces. This means that each space is maximally labeled as many times as the number of its contiguous spaces. The labels of a space are ordered on the basis of a priority list that reflects the stylistic preferences of the particular design class. Grouping of spaces uses the ordered space labels as criteria. The groups returned by this process agree with human intuitive perception of spatial grouping in the floor plan, as well as with expert architectural knowledge. For example, Palladian floor plans are consistently grouped into a central space group flanked by two symmetric space groups.

doi	https://doi.org/10.52842/conf.acadia.2000.281
summary	Disability is a product of the interactions between individuals and the environment they inhabit and the products they utilize. Disability is located on a continuum from enablement to disablement. Human physical characteristics as well as environmental factors will locate an individual on that continuum. The degree of disability or enablement will fluctuate, depending upon the attributes of the environment and the artifacts located there. The ability of designers and architects to create environments and products that enable all people is directly tied to their ability to: 1. understand the abilities and constraints of the human body and, 2. model the physics of the body’s interactions with artifacts and spaces. // This project is developing an anthropometric measurement protocol and computer-based design tools focusing on people with disabilities and the aging. The areas of interest for measurement are guided by real-world design needs. The measurements generated are translated into three-dimensional datasets compatible with commercial off the shelf software extended by the programming of additional scripts, functions, plug-ins, behaviors, etc.

title	Autonomous Spatial Redistribution for Cities
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 678-684
doi	https://doi.org/10.52842/conf.ecaade.1999.678
summary	The paper investigates an automated methodology for the appropriate redistribution of usable space in distressed areas of inner cities. This is achieved by categorising activity space and making these spaces morphologically mobile in relation to the topography within a representative artificial space. The educational module has been influenced by theories from the natural environment, which possess patterns that have inherent evolutionary programmes in which the constituents are recyclable, Information is strategically related to the environment to produce forms of growth and behaviour. Artificial landscape patterns fail to evolve, the inhabited landscape needs a means of starting from simplicity and building into the most complex of systems that are capable of re-permutation over time. The paper then describes the latest methodological development in terms of a shift from the use of the computer as a tool for data manipulation to embracing the computer as a design partner. The use of GDL in particular is investigated as a facilitator for such generation within a global, vectorial environment.
