title Schematic design system for flexible and multi-aspect design thinking
source Automation in Construction 11 (2) (2002) pp. 147-159
summary A designer-friendly CAD for a schematic design is one of the important topics of CAD studies. There were attractive preceding studies aiming to develop a CAD that intended to enable designers to have flexible design thinking and interactively manipulate representation models. This paper has the same goals of study, but focuses on the needs to support flexible and multi-aspect design thinking. Though designers normally hope to elaborate on their ideas using separate sets of representation models suitable for respective studies, a present CAD that is designed to build a single set 3D model, has limited its ability as a tool for a schematic design. Assuming this as the base concept, authors have studied to develop a prototype of a schematic design system, customizing AutoCAD R14J: Schematic Design System '98 (SDS'98). It has convenient utilities both for building separate sets of representation models and for integrating and reconciling those models to build a single consolidate model. This paper discusses the common procedures of schematic design studies, necessary functional features for SDS, a case study of the system use, and finally, the advantages and the disadvantages of the proposed system.

title Auto-Generative Urban Interventions: A Study of the Relationship between Building Form Generation and Urban Context Mapping
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 297-298
summary This project documents the progress of research developed to explore the unique relationship between building form and urban context with the application of a novel auto-generative modeling process incorporated into a speculative design methodology. The techniques and parameters for the project are reviewed relative to key concepts of D’Arcy Thompson’s dynamic “theory of transformation” and the development of the auto-generative modeling process. This is followed by a detailed discussion of the set of exchanges between the urban context (field of influence) and the formation of the building intervention that were subsequently mappedthrough a series of diagramming studies. Specific issues explored in the project focus on Thompson’s descriptive analysis of form as a “diagram of forces” and his use of flexible, deformable topological Cartesian nets (Method of Coordinates) to subject the stasis of geometric types to dynamic transformation. Some preliminary interpretations of the project results are evaluated through studies of the generative schemes deployed in different urban situations. The initial results of the study are demonstrated with a resultant schematic building design for a modest scaled intervention in the city of Miami.

title Interactive Storytelling and Its Role in the Design Process

source CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 151-158
summary Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

title Strategic Briefing A Conceptual Process Model for Building Design
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Nowadays building design problems are divided in partial discipline related sub-problems. Through targeted and focused attention to sub problems however the awareness of the whole is lost. Each designparticipant gives his sub-problem first priority. In contrast in the past the master builder saw the whole problem as his problem first. Thus the process of seeing the design problem as a whole, as a result ofprioritizing, considering constraints, or strategizing, is lost in today’s practice, basically because this process is a mental and implicit process, that occurred in the brain of the multi-disciplinary master builder.In most cases it is the task of no one in a design team today. The aim of this paper is modeling this conceptual mental implicit process design using System Theory and Cognitive Psychology, trying to determine the structure of the design problem as it occurs intuitively in the brain. The result will provide us with a mechanism that enables us each time to refine a unique common design problem representation. This leads to more effective use of design team capabilities, and forms an essential basis for organizing efforts toward collaborative solutions. Also some kind of clarity is provided as to how proposed solutions are to be judged.

title Cognitive Biases and Precedent Knowledge in Human and Computer-Aided Design Thinking

summary Cognitive biases (illusions) and potential errors can occur when using precedent knowledge for analogical, pre-parametric and qualitative design thinking. This paper refers largely to part of a completed research (Bay 2001) on how heuristic biases, discussed by Tversky and Kahneman (1982) in cognitive psychology, can affect judgement and learning of facts from precedents in architectural design, made explicit using a kernel of conceptual system (Tzonis et. al., 1978) and a framework of architectural representation (Tzonis 1992). These are used here to consider how such illusions and errors may be transferred to computer aided design thinking.

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

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. 282-289
summary Most departmental computing infrastructure reflects the state of networking technology and available funds at the time of construction, which converge in a preconceived notion of homogeneity of network architecture and usage patterns. The DMAN (Digital Media Access Network) project, a large-scale server and network foundation for The Hong Kong Polytechnic University’s School of Design, was created as a platform that would support a highly complex academic environment while giving maximum freedom to students, faculty and researchers through simplicity and ease of use. As a centralized multi-user computation backbone, DMAN faces an extremely heterogeneous user and application profile, exceeding implementation and maintenance challenges of typical enterprise, and even most academic server set-ups. This paper summarizes the specification, implementation and application of the system while describing its significance for design education in a computational context.

title Towards a multi-agent model for visualizing simulated user behavior to support the assessment of design performance
source Automation in Construction 11 (2) (2002) pp. 135-145
summary We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better understanding of what the design will look like, especially for those cases where design or planning decisions will affect the behavior of individuals. The system is based on cellular automata and multi-agent simulation technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. Each agent will be located in a simulated space, based on the cellular automata grid. Each iteration of the simulation is based on a parallel update of the agents conforming local rules. Agents positioned within an environment will need sensors to perceive their local neighborhood and some means with which to affect the environment. In this way, autonomous individuals and the interaction between them can be simulated by the system. As a result, designers can use the system to assess the likely consequences of their design decisions on user behavior. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior in architecture and urban planning.

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.

summary We present an agent-based system for capturing and indexing software design meetings. During these meetings, designers design object-oriented software tools, including new agent-based technologies for the Intelligent Room, by sketching UML-type designs on a white-board. To capture the design meeting history, the Design Meeting Agent requests available audio, video, and screen capture services from the environment and uses them to capture the entire design meeting. However, finding a particular moment of the design history video and audio records can be cumbersome without a proper indexing scheme. To detect, index, and timestamp significant events in the design process, the Tahuti Agent, also started by the Design Meeting Agent, records, recognizes, and understands the UML-type sketches drawn during the meeting. These timestamps can be mapped to particular moments in the captured video and audio, aiding in the retrieval of the captured information. Metaglue, a multiagent system, provides the computational glue necessary to bind the distributed components of the system together. It also provides necessary tools for seamless multi-modal interaction between the varied agents and the users.

summary To make whole one image on screens that is generated by many computers and synchronization among computers, there is a need for a network software environment for multi-projector display system. Although the development costs increase for parallel programming for multi-projector display system, there is a possibility that the program cannot be executed at an enough speed since the network bandwidth might become a bottleneck. There are some software environments for that kind of multi-projector display system like Chromium that is latest version of WireGL (Humphreys, 2001&2002). WireGL is a kind of Client-Server Model, which one rendering server sends the data of rendering to many computers. While it can use the application without modification of source, it requires heavy network traffics. The other type of operating software is VR Juggler (Cruz-Neira, 2002), and CAVE Library that is a kind of Master-Slave Model. In the Master-Slave Model, every computer has same application programs to render the image that only keep the synchronization of rendering and events. But, these programs require a specialized skill and knowledge to modify the source of program for the certain rendering PC-Cluster system.

summary In this paper, we propose an agent based collaborative design environment in which human designers and software agents interact with each other, exchange design information and keep track of state information to assist with collaborative design. First of all, it presents a hierarchical multi-agent system architecture for integrating design and engineering tools, software agents and human specialists in an open environment. The hierarchical multi-agent system architecture offers a promising framework with their novel approaches for dynamically creating and managing design tasks in widely distributed and ever-changing design environments. Secondly, it introduces a collaborative design process model and the dynamic management approach for collaborative design process. Then, the structure of a design agent, its static knowledge and dynamic knowledge are introduced respectively. The knowledge based design approach provides a foundation for supporting reusable design activities. Finally, the cooperative design process is illustrated by a bicycle design example.

summary Previous work by Professor John Frazer on Evolutionary Architecture provides a basis for the development of a system evolving architectural envelopes in a generic and abstract manner. Recent research by the authors has focused on the implementation of a virtual environment for the automatic generation and exploration of complex forms and architectural envelopes based on solid modelling techniques and the integration of evolutionary algorithms, enhanced computational and mathematical models. Abstract data types are introduced for genotypes in a genetic algorithm order to develop complex models using generative and evolutionary computing techniques. Multi-objective optimisation techniques are employed for defining the fitness function in the evaluation process.

summary Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title Visual Keys to Architectural Design
doi https://doi.org/10.52842/conf.caadria.2002.175
source CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 175-182
summary This paper presents a new mechanism to access and interact with DYNAMO, a collective case base for architectural design developed as a Web-based tool. The system is fully operational since a few years in the context of architectural design education as well as for seminars on architectural theory. We have now developed a set of visual keys structured at the one hand according to the Vitruvian tripartition of architecture: Firmitas (structure, materials,…), Utilitas (building programme,…), Venustas (formal qualities/articulation, spatial configuration,…) to which we added Context (topography, site, budget, climate,...) as a supplementary dimension, and at the other hand including three levels of detail: single spaces, building blocks or master plan entities. Visual keys match the architect’s designerly way of thinking. The visual keys are in fact nothing else than a graphical codification of architecture within the realm of architectural composition. The software, that has been developed so far, does not only allow users to access cases via the keys we have implemented, but it also provides a tool to sketch and submit their own keys.

title Towards a Local Planning Support System,Introducing the MASQUE Framework
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary Urban planning is an important instrument for improving the quality of life, but it is hampered by the fact that the effects of many decisions, to be made by the planner, are practically unknown or at best unclear. The high level of complexity, uncertainty and subjectivity involved in urban plan development is seriously troubling the planner. One way of facilitating the plan development process, and potentially improving the decision-making, is developing a Planning Support System (PSS) that combines artificialintelligence with a gamut of computational tools that support the process. At the Eindhoven University of Technology a research program is conducted to develop such a system for local urban planning in the Netherlands. The system, named MASQUE (Multi-Agent System for supporting the Quest forUrban Excellence), applies Multi-Agent technology to incorporate multidisciplinary expertise on both tools and domains as well as to enable intelligent guidance and assistance towards the user. Strong emphasis is put on the scenario-based way of working that is common in urban planning. This paper puts forward the difficulties faced in local planning practice and discusses the possibilities for computer-assistance. This finally resolves into the introduction of the MASQUE framework, describing how the system is organized and how the agents will be involved.

title Curious Design Agents and Artificial Creativity - A Synthetic Approach to the Study of Creative Behaviour
source The University of Sydney, Faculty of Architecture
summary Creative products are generally recognised as satisfying two requirements: firstly they are useful, and secondly they are novel. Much effort in AI and design computing has been put into developing systems that can recognise the usefulness of the products that they generate. In contrast, the work presented in this thesis has concentrated on developing computational systems that are able to recognise the novelty of their work. The research has shown that when computational systems are given the ability to recognise both the novelty and the usefulness of their products they gain a level of autonomy that opens up new possibilities for the study of creative behaviour in single agents and the emergence of social creativity in multi-agent systems. The work presented in this thesis has developed a model of curiosity in design as the selection of design actions with the goal of generating novel artefacts. Agents that embody this model of curiosity are called “curious design agents”. The behaviour of curious design agents is demonstrated with a range of applications to visual and nonvisual design domains. Visual domains include rectilinear drawings, Spirograph patterns, and “genetic artworks” similar to the work of Karl Sims. Non-visual domains include an illustrative abstract design space useful for visualising the behaviour of curious agents and the design of doorways to accommodate the passage of large crowds. The design methods used in the different domains show that the model of curiosity is applicable to models of designing by direct manipulation, parametric configuration or by using a separate design tool that embodies the generative aspects of the design process. In addition, an approach to developing multi-agent systems with autonomous notions of creativity called artificial creativity is presented. The opportunities for studying social creativity in design are illustrated with an artificial creativity system used to study the emergence of social notions of whom and what are creative in a society of curious design agents. Developing similar artificial creativity systems promises to be a useful synthetic approach to the study of socially situated, creative design.

title Requirements for Collaborative Design in Architecture
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary The concept of collaborative design has recently come under renewed attention in the field of computer aided architectural design support. Although collaborative design deals with the same aspects of cooperation by various participants in the design process as previously studiedin, for example, concurrent engineering and multi-disciplinary design, it nevertheless puts a different research emphasis. Collaborative design looks at how the process can be improved in such a way that collaboration –working together in a manner to enhance each participants contribution to the design– emerges from the process. In engineering design practice, thismeans a shift forward in the design process where engineers are asked earlier for their input in the design solution. For CAAD research, the phenomenon of collaborative design poses the question how design tools and environments can be made in such a way that collaboration will occur. In this paper, the aims is to describe the concept of collaborative design in architecture, and to give an outline of the perceived requirements in the organisation of design and Computer Aided Design Support to achieve collaborative design.

title An Agent Framework for Recognition of Graphic Units in Drawings
doi https://doi.org/10.52842/conf.ecaade.2002.246
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. 246-253
summary Architects use graphic conventions in their drawings that have meaningful content to the design task. In previous work, such well-defined sets of graphic entities have been identified and defined. These sets are called graphic units. In this paper, we discuss how graphic unit recognition in drawings can take place using a multi-agent systems approach. This approach seems promising as singular agents may specialize in graphic unit-recognition, and multi-agent systems can address problems of ambiguity through negotiation mechanisms. We present an agent framework for this purpose, how it connects to the theory of graphic units, and how agents for recognizing graphic units are defined. The paper ends with a discussion of current findings and future work.
