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 Creative Individuals or Creative Situations? A Computational Model of Creativity Based on Social Influence
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 31-34
summary Computers can be used as a key research tool because they allow us to do things that have been difficult or unfeasible in the past. This potential could facilitate discussion of ideas in new ways. This paper presents preliminary findings of a computational model that may contribute to extend our –presently limited – understanding of creative phenomena in design. As part of an extensive modelling effort, it offers initial insights that may shift the current focus in individual creativity to a more extensive view where the situations within which designers operate play a key role in the occurrence and definition of creativity.

title Models of Design Requirement
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Case studies show that significant proportions of design errors and failures are linked to poor requirement specification during both early stages of design and as changes occur. Computational requirements engineering as a front-end to design iterations is a promising area addressing theseproblems. In other design disciplines, such as in software engineering, requirement engineering has given significant product improvements. In this paper, we present a state-space representation of requirement models for architectural design. The purpose of requirement modeling in design is tocreate a process by which requirements can be converted into working design solutions through frontend validation. We suggest three models of requirement specification, co-evolutionary [CoM], multiple domain [MDM] and single domain [SDM] models, that can facilitate this effort. Taken together all three models provide a full set of logical permutations of requirement-solution “worlds” and “operations.” We compare each model against the others in terms of facilitating change management and computability.

summary This paper describes both conventional and computational ways of expressing and exploring design concepts with the use of models. We explain the role and function of the model in the design process, and investigate the ways in which models become reflections and representations of architects’ design thinking. We compare and contrast the physical properties of conventional models with those of three-dimensional computer models, and the corresponding processes of model creation, model development, and model modification. The paper includes a brief overview of commonly used forms of computer representations often encountered in Computer Aided Design applications. Whatever the visual richness of computer models in virtual environments can be, we believe that, just as in the use of conventional two-dimensional architectural drawings, computational presentations of architectural design concepts have their own conventions of use. This paper addresses the need to more accurately understand these conventions of using computer models for the representation of architectural design concepts. Therefore, we will illustrate the more dynamic qualities of computer models, which have the potential to allow designers to escape from the restrictions and constraints of physical form. In particular, we demonstrate these qualities in the context of architectural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.

title Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d ‘Compressed’ Components
doi https://doi.org/10.52842/conf.ecaade.2009.021
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 21-30
summary Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D ‘compressed’ components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity ‘capable’ software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title Information Amount Measurement in Generative Systems:An Objective Approach to Termination
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Termination in computational generative systems is linked increasingly to user intervention: the generative system concludes when the user chooses it to do so. The similarities between this approach to termination and the creative artistic process suggest that the products of generative systems are amenable to analysis in terms of well-formedness leading to a formal measure that acts as an automatic termination trigger. The paper proposes that such a measure can be derived from structural information theory. By applying the compression of structural information theory to meaningful principles of a design world we derive a consistent, universal description of the design result at any given state. This description expresses the correlation of the design with its formal constraints, as well as the general perception of the design’s patterns.

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.

title Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 451-476.
summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

summary In this paper the possibilities of using the computers at course of architectural compositions are considered. As the start point of the new teaching method of architectural composition we used the course of tradition architectural composition, elaborated at our Faculty. The course of Digital Architectural Composition was finished in 2002. The main goal of using the new digital media for modelling architectural forms was checking the new possibilities of form creation. Traditionally, searching of forms at the conceptual design stage is performed by using sketches, drawings and physical models. Our new method showed that is possible to do the same thing using the computerbased 3D modelling, experiencing no physical limitations of the 'real' substance. At the same time, at the early design stages, when formal value is sought, computer modelling can be done almost intuitively. In ours work we try to find a creative way of using computer - transforming the tool into medium. The attention was paid on exploring the possibilities characteristic for computers and not available with traditional methods of modelling. Architect’s tradition tools are effectively replaced by a computer, which create a new way of doing things.

title Flexible and distributed coordination models for collaborative design

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. 268-275
summary Designers working in collaborative design situations, attempt to plan or anticipate their activities, such that their work progresses in an orderly manner, according to technical demands of their domain. Designers, and the organizations that employ them, often attempt to formally represent such plans using process representations, such critical path diagrams, or Petri nets. Such process articulation and formalization can have benefits for designers and organizations, such as standardization and improvement of work practices, and improved collaboration and coordination between design parties. In addition to plan making, designers also try to coordinate their actions with the actions of others on the design team. This coordination, which often takes place in real time, is a process that is necessarily social, interactive, and iterative. Here the formulation of suitable process representations is more difficult, due to the dynamic and complex nature of social interactions. How to represent and design such coordination processes, is a continuing research question in the process modeling community. It is possible there exists general coordination mechanisms that could be useful in a variety of domains. Possibilities for distributed methods of design process coordination are examined. A coordination method is proposed that involves the exchange of design process models, represented as Petri nets. Rather than concentrating on the specific content of these models - which is assumed to vary considerably between design domains - general coordinating mechanisms are proposed. One such mechanism involves the communication of social commitments to process models, in addition to communication of the content and authorship of these models.

title Physical and Virtual Tools: Activity Theory Applied to the Design of Groupware
source Computer Supported Cooperative Work (CSCW), Kluwer
summary Activity theory is based on the concept of tools mediating between subjects and objects. In this theory, an individual's creative interaction with his or her surroundings can result in the production of tools. When an individual's mental processes are exteriorized in the form of tools - termed objectification - they become more accessible to other people and are therefore useful for social interaction. This paper shows how our understanding of activity theory has shaped our design philosophy for groupware and how we have applied it. Our design philosophy and practice is exemplified by a description of the BUILD-IT system. This is an Augmented Reality system we developed to enhance group work; it is a kind of graspable groupware which supports cooperative planning. The system allows a group of people, co-located around a table, to interact, by means of physical bricks, with models in a virtual three-dimensional (3D) setting. Guided by task analysis, a set of specific tools for different 3D planning and configuration tasks was implemented as part of this system. We investigate both physical and virtual tools. These tools allow users to adjust model height, viewpoint, and scale of the virtual setting. Finally, our design practice is summarized in a set of design guidelines. Based on these guidelines, we reflect on our own design practice and the usefulness of activity theory for design.

title An Innovative Model of the Building Development ProcessDesign as a Process of Crystallisation
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In the past, models describing the development of artefacts, including buildings, usually were of a linear nature thereby suggesting a sequential path from conception of the artefact to its completion. This has consequences for the sequence of activities in the design and programming phase. However, designing is basically a thinking activity and is as such not bound to the same laws as e.g. the construction process. This must have repercussions for the way the design process is designed andmanaged. The proposed conceptual model of the artefact development process – in this case a building design process – is a kind of framework which is more in accordance with the nature of thinkingactivities. It should stimulate a non-sequential process. The development of a solution to a design problem thus should become a responsive search process driven by insights and creative leaps but guided by the framework the model provides. Furthermore, the model is meant to support the exploration and clarification of the problem as well as to extend the solution space by various means such as the development of scenarios and strategic values as a basis for the realisation of the building project’s goals. This model is an essential element in the development of an innovative approach towards the process design of the building design process. The creation of a building (conception, design and development) is not considered a sequential process but a process of crystallisation with the potential of developing in all directions, thus growing from a conceptual centre outwards.

summary Architecture is built information (Schmitt, 1999). Architects have the task of restructuring and translating information into buildable designs. The beginning of the design process where the briefing is transformed into an idea is a crucial phase in the design process. It is where the architect makes decisions which influence the rest of the design development process (Vries et al., 1998). It is at this stage where most information is unstructured but has to be integrated into a broad context. This is where TAP is positioned – to support the architect in finding solutions through the creation of spatially structured information sets without impairing thereby the creative development. We want to enrich the inspiration of an architect with a new kind of information design. A further aspect is workflow in a distributed process where the architect’s work becomes one aspect of a decentralised working patterns. The software supports collaborative work with models, sketches and text messages within an uniform surface. The representations of the various media are connected and combined with each other and the user is free to combine them according to his or her needs.

title Design Decision Support through Translation between Multiple Representations of Spatial Data
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Urban planning and urban design involve collaboration of diverse participants with multiple agendas and multiple criteria. The participants typically use multiple representations of spatial data to derive inferences and insights about the planning problems, leading to a shared decision-making process. To support such multidisciplinary work, this paper proposes a new computational approach and technique for translation between multiple representations of spatial data. This approach is designed to supportdesign decision-making in the interrelated interests of design participants. Prototype implementation and evaluation are conducted to test and validate the proposals.
