title The Future of VRML on Large Urban Models.
source The 4th UK VRSIG Conference
summary In this paper, the suitability and usability of VRML for urban modelling is discussed based on the experience gained by the creation of urban models of varying sizes, level of detail and use. Areas where the current VRML specification is failing to satisfy the needs of large-scale urban modelling are highlighted. Properties of a successful alternative or VRML3.0 specification are suggested and briefly discussed.

summary Large-scale, three dimensional, interactive computer models of cities are becoming feasible making it possible to test their suitability as a visualisation tool for the design and planning process, for data visualisation where socio-economic and physical data can be mapped on to the 3D form of the city and as an urban information repository. The CASA developed models of the City of Bath and London's West End in VRML format, are used as examples to illustrate the problems arising. The aim of this paper is to reflect on key issues related to interaction within urban models, data mapping techniques and appropriate metaphors for presenting information.

title Shared Information System for Urban and Architectural Design
source Coyne, R. Ramscar, M. Lee, J. and Zreik, K. (eds.) Design and the net. Proceedings of the Sixth International EuropIA Conference, Europia Productions, Paris, pp. 39-52
summary This paper briefly describes the implementation of an Internet-intranet information system applied to a large-scale project. The large-scale project is centered on the urban area around the Porta Susa railway station in Turin, Italy. The information system integrates the communicative tools used to facilitate and improve the collaboration between the different actors working on the project and the distributed environment used to elaborate the information across a wide area network. The main factors considered are those which exploit the potentialities of computers and networks for interaction and communication. One result is the possibility of interacting dynamically with the information, re-elaborating and distributing it in progress. The information systems opens different ways of collaboration between the project employees, and extends the participation in the project to the citizens.

title Shared Virtual Reality for Architectural Design
source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 431-442
summary The paper presents the implementation of a system of Shared Virtual Reality (SVR) in Internet applied to a large- scale project. The applications of SVR to architectural and urban design are presented in the context of a real project, the new railway junction of Porta Susa and the surrounding urban area in the city centre of Turin, Italy. SVR differs from Virtual Reality in that the experience of virtual spaces is no longer individual, but rather shared across the net with other users simultaneously connected. SVR offers an effective approach to Computer Supported Collaborative Work, because it integrates both the communicative tools to improve collaboration and the distributed environment to elaborate information across the networks.

summary Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

title Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
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. 637-652.
summary Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming “design challenges on a much larger scale as we become an increasingly global and technological society” (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design – such as Second Life and There – are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.

title Three-dimensional object reconstruction from two-dimensional images
source Computer-Aided Design, Vol. 29 (4) (1997) pp. 279-285
summary In order to construct a 3D model from a collection of 2D images of an object, an energy function is defined between the object's images and corresponding images ofan articulated mesh in three dimensions. Repeated adjustment of the mesh to minimize the energy function results in a mesh that produces images which closelyapproximate the input images, that is to say that under the appropriate conditions it realizes a preconceived object. It has implications for model building, reverseengineering and computer vision. Minimization of the energy function is a multivariate problem of large scale with many local minima. We give an approach forsolving this problem. For certain restricted, but useful applications, intuitive solutions to the minimization are consistently obtained.

title Computers for Windows: Interactive Optimization Tools for Architects designing openings in walls (IOTA)
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi https://doi.org/10.52842/conf.ecaade.1997.x.d4u
summary Size, shape and disposition of windows in walls has long been an integral expression of style in architecture. As buildings have grown taller the relationships of the windows to the ground plane and to the surrounding environments have become more complex and difficult to predict. Traditionally architects have had to use their own knowledge, experience and feelings in the design of windows. There may be few, if any, scientific bases for their decisions. The difficulty in making good design decisions is compounded because many criteria for window design, such as daylight, sunlight, ventilation, sound, view and privacy have to be considered simultaneously. It is here that computers can help, on the one hand, by providing ‘expert knowledge’ so that architects can consult the cumulative knowledge database before making a decision, whilst on the other hand, evaluations of the decisions taken can be compared with a given standard or with alternative solutions.

‘Expert knowledge’ provision has been made possible by the introduction of hypertext, the advancement of the world wide web and the development of large scale data-storage media. Much of the computer’s value to the architects lies in its ability to assist in the evaluation of a range of performance criteria. Without the help of a computer, architects are faced with impossibly complex arrays of solutions. This paper illustrates an evaluation tool for two factors which are important to the window design. The two factors to be investigated in this paper are sunlighting and views out of windows.

Sunlight is a quantitative factor that can theoretically be assessed by some mathematical formulae provided there is sufficient information for calculation but when total cumulative effects of insolation through the different seasons is required, in addition to yearly figures, a design in real-time evolution requires substantial computing power. Views out of windows are qualitative and subjective. They present difficulties in measurement by the use of conventional mathematical tools. These two fields of impact in window design are explored to demonstrate how computers can be used in assessing various options to produce optimal design solutions. This paper explains the methodologies, theories and principles underlying these evaluation tools. It also illustrates how an evaluation tool can be used as a design tool during the design process.

title Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source Eindhoven University of Technology
summary The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process. Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type. A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent. If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used. By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined. The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design. Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

source AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 83-92
summary In Sweden representatives from the Construction industry have put forward a research and development program called: "IT-Bygg 2002 -Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. A seminar was held with some of the most experienced researchers, developers and practitioners of CAD in construction in Sweden. The activities were recorded and annotated, analysed and put together afterwards; then presented to the participants to agree on. Co-operation is the key to get to the goals - IT and CAD are just the means to improve it. Co-operation in a phase of implementation is enough problematic without the technical difficulties in using computer programs created by the computer industry primarily for commercial reasons. The suggestion is that cooperation between software companies within Sweden will make a greater market to share than the sum of all individual efforts. In the short term, 2 - 5 years, implementation of CAD and IT will demand a large amount of educational efforts from all actors in the construction process. In the process of today the architect is looked upon as a natural coordinator of the design phase. In the integrated process the architect's methods and knowledge are central and must be spread to other categories of actors - what a challenge! At least in Sweden the number of researchers and educators in CAAD is easily counted. How do we make the most of it?

title RealSpace in QuickTimes: architecture and digitization
source Rotterdam: Nai Publishers
summary Time and space, drastically compressed by the computer, have become interchangeable. Time is compressed in that once everything has been reduced to 'bits' of information, it becomes simultaneously accessible. Space is compressed in that once everything has been reduced to 'bits' of information, it can be conveyed from A to B with the speed of light. As a result of digitization, everything is in the here and now. Before very long, the whole world will be on disk. Salvation is but a modem away. The digitization process is often seen in terms of (information) technology. That is to say, one hears a lot of talk about the digital media, about computer hardware, about the modem, mobile phone, dictaphone, remote control, buzzer, data glove and the cable or satellite links in between. Besides, our heads are spinning from the progress made in the field of software, in which multimedia applications, with their integration of text, image and sound, especially attract our attention. But digitization is not just a question of technology, it also involves a cultural reorganization. The question is not just what the cultural implications of digitization will be, but also why our culture should give rise to digitization in the first place. Culture is not simply a function of technology; the reverse is surely also true. Anyone who thinks about cultural implications, is interested in the effects of the computer. And indeed, those effects are overwhelming, providing enough material for endless speculation. The digital paradigm will entail a new image of humankind and a further dilution of the notion of social perfectibility; it will create new notions of time and space, a new concept of cause and effect and of hierarchy, a different sort of public sphere, a new view of matter, and so on. In the process it will indubitably alter our environment. Offices, shopping centres, dockyards, schools, hospitals, prisons, cultural institutions, even the private domain of the home: all the familiar design types will be up for review. Fascinated, we watch how the new wave accelerates the process of social change. The most popular sport nowadays is 'surfing' - because everyone is keen to display their grasp of dirty realism. But there is another way of looking at it: under what sort of circumstances is the process of digitization actually taking place? What conditions do we provide that enable technology to exert the influence it does? This is a perspective that leaves room for individual and collective responsibility. Technology is not some inevitable process sweeping history along in a dynamics of its own. Rather, it is the result of choices we ourselves make and these choices can be debated in a way that is rarely done at present: digitization thanks to or in spite of human culture, that is the question. In addition to the distinction between culture as the cause or the effect of digitization, there are a number of other distinctions that are accentuated by the computer. The best known and most widely reported is the generation gap. It is certainly stretching things a bit to write off everybody over the age of 35, as sometimes happens, but there is no getting around the fact that for a large group of people digitization simply does not exist. Anyone who has been in the bit business for a few years can't help noticing that mum and dad are living in a different place altogether. (But they, at least, still have a sense of place!) In addition to this, it is gradually becoming clear that the age-old distinction between market and individual interests are still relevant in the digital era. On the one hand, the advance of cybernetics is determined by the laws of the marketplace which this capital-intensive industry must satisfy. Increased efficiency, labour productivity and cost-effectiveness play a leading role. The consumer market is chiefly interested in what is 'marketable': info- and edutainment. On the other hand, an increasing number of people are not prepared to wait for what the market has to offer them. They set to work on their own, appropriate networks and software programs, create their own domains in cyberspace, domains that are free from the principle whereby the computer simply reproduces the old world, only faster and better. Here it is possible to create a different world, one that has never existed before. One, in which the Other finds a place. The computer works out a new paradigm for these creative spirits. In all these distinctions, architecture plays a key role. Owing to its many-sidedness, it excludes nothing and no one in advance. It is faced with the prospect of historic changes yet it has also created the preconditions for a digital culture. It is geared to the future, but has had plenty of experience with eternity. Owing to its status as the most expensive of arts, it is bound hand and foot to the laws of the marketplace. Yet it retains its capacity to provide scope for creativity and innovation, a margin of action that is free from standardization and regulation. The aim of RealSpace in QuickTimes is to show that the discipline of designing buildings, cities and landscapes is not only a exemplary illustration of the digital era but that it also provides scope for both collective and individual activity. It is not just architecture's charter that has been changed by the computer, but also its mandate. RealSpace in QuickTimes consists of an exhibition and an essay.

summary A new method of describing designs by combining the paradigms of shape algebras and predicate logic representations is presented. Representing shapes and spatial relations in logic provides a natural, intuitive method of developing complete computer systems for reasoning about designs. The advantages of shape algebra formalisms over more traditional representations of geometric objects are discussed. The method employed involves the definition of a large set of high level design relations from a small set of simple structures and spatial relations. Examples in architecture and geographic information systems are illustrated.

summary Generative design systems take an active part in the generation of computational design models. They make it easier for designers to explore conceptual alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed to enable designers to access the information with ease and low cognitive loads. We present an approach to support navigation in generative design systems. Our approach takes account of studies related to navigation in physical environments as well as information navigation in electronic media. Results of studies from the physical environment and electronic media reveal that 1) people exhibit similar cognitive behaviours (spatial cognition and the use of spatial knowledge) while navigating in physical and information spaces; and 2) the information space lacks legibility and imageability. The proposed information navigation model take these findings into account.

title Towards a Taxonomy of Virtual Reality User Interfaces
source Proceedings of the International Conference on Information Visualisation (IV97), pp. 17-29
summary Virtual reality based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application oriented knowledge is available. As a basis for such a future VRUI design theory, a taxonomy of VRUIs is required. A general model of human computer communication is formulated. This model constitutes a frame for the integration of partial taxonomies of human computer interaction that are found in the literature. The whole model constitutes a general user interface taxonomy. The field of VRUIs is described and delimited with respect to this taxonomy.

summary IT is just a tool, but the most powerful one ever to be offered to us. This case study deals with the areas at which IT can be targeted within the Building Design Partnership. Firstly, should anything be done and if so, what criteria should be used to choose the priorities? A SWOT analysis is one way way to identify goals. Strengths/weeknesses, opportunities/threats are the positive/negative pairs. We have to build our strength and perceive and take opportunities while at the same time countering weaknesses and threats. It is a threat that the industry sets a moving target of IT capability without wanting to meet its cost. It is an opportunity that only a few practices will be at the leading edge and that they will secure the key projects. IT could help us to overcome technical weaknesses and liability and reduce staff and premises costs. It could also increase our exposure to fixed capital costs in a cyclical business. IT could increase the success of integrated practice or it could make it easier for separate firms. We believe the likelihood is that IT will do as it has for financial services and favour the large, multi-national, well prepared and technologically advanced firms. New services will emerge and become assential and will separate the `sheep from the goats.'

title Advances in control systems for construction manipulators
source Automation in Construction 6 (3) (1997) pp. 193-203
summary Fundamental advances in sensors, actuators, and control systems technology are creating opportunities to improve the performance of traditional construction equipment. New capabilities are being developed as well. These improvements in performance and new capabilities are resulting in better safety and efficiency. However, selecting control strategies can be confusing, and measuring and predicting their performance can be difficult. This paper identifies emerging control paradigms and describes methods for measuring their performance. Many control schemes and corresponding example applications are identified, including single degree of freedom control sticks, multiple degree of freedom joysticks, operating and safety constraints, teach/learn capability, resolved motion with internal and external sensors, spatially correspondent controllers, tele-operation, graphical programming and control, and autonomous controls. Methods described for measuring performance are based on American National Standard Institute (ANSI) standard tests, applications analysis, and ergonomics. Examples focus on the University of Texas at Austin's large scale hydraulic manipulator (LSM) and Automated Road Maintenance Machine (ARMM) with the results of performance tests on these manipulators being presented.

title Punching Above Your Weight: Digital Design Methods and Organisational Change in Small Practice
source Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 40-47
doi https://doi.org/10.52842/conf.acadia.2007.040
summary Expanding bodies of knowledge imply expanding teams to manage this knowledge. Paradoxically, it can be shown that in situations of complexity—which increasingly characterise the production of architecture generally—the small practice or small team could be at an advantage. This is due to the increasingly digital nature of the work undertaken and artefacts produced by practices, enabling production processes to be augmented with digital toolsets and for tight project delivery networks to be forged with other collaborators and consultants (Frazer 2006). Furthermore, as Christensen argues, being small may also be desirable, as innovations are less likely to be developed by large, established companies (Christensen 1997). By working smarter, and managing the complexity of design and construction, not only can the small practice “punch above its weight” and compete with larger practices, this research suggests it is a more appropriate model for practice in the digital age. This paper demonstrates this through the implementation of emerging technologies and strategies including generative and parametric design, digital fabrication, and digital construction. These strategies have been employed on a number of built and un-built case-study projects in a unique collaboration between RMIT University’s SIAL lab and the award-winning design practice BKK Architects.

title THE ELEMENTS OF DESIGN INFORMATION FOR PARTICIPATION IN NEIGHBORHOOD-SCALE PLANNING

summary Neighborhood scale planning and design in many communities has been evolving from a rule-based process of prescriptive codes and regulation toward a principle- and performance-based process of negotiated priorities and agreements. Much of this negotiation takes place in highly focused and interactive workshop or 'charrette' settings, the best of which are characterized by a fluid and lively exchange of ideas, images and agendas among a diverse mix of citizens, land owners, developers, consultants and public officials. Crucial to the quality and effectiveness of the exchange are techniques and tools that facilitate a greater degree of understanding, communication and collaboration among these participants.

Digital media have a significant and strategic role to play toward this end. Of particular value are representational strategies that help disentangle issues, clarify alternatives and evaluate consequences of very complex and often emotional issues of land use, planning and design. This paper reports on the ELEMENTS OF NEIGHBORHOOD, a prototype 'electronic notebook' (relational database) tool developed to bring design information and example 'to the table' of a public workshop. Elements are examples of the building blocks of neighborhood (open spaces, housing, commercial, industrial, civic and network land uses) derived from built examples, and illustrated with graphic, narrative and numeric representations relevant to planning, design, energy, environmental and economic performance. Quantitative data associated with the elements can be linked to Geographic Information based maps and spreadsheet based-evaluation models.

title A standards processing framework
source Carnegie Mellon University, Pittsburgh
summary Civil engineers create and employ a very large number of design standards, especially in the United States. Designing using such a large number of design standards is a tedious, laborious, and difficult task. One major research task in Computer-Aided Engineering (CAE) is the development of software tools that assist in the usage of design standards during the design process. This dissertation, a standards processing framework is presented. It is an agent-based approach to providing computer-aided support for using design standards. In this framework, modules, such as standards processing servers, are treated as agents communicating using a defined communication language. One immediate advantage of this architecture is that it allows the incorporation of a broad, powerful set of representation for use in modeling design standards.

title Chips, chunks and sauces
source International Journal of Design Computing, 1, 1997 (Editorial)
summary I am sure there is an art in balancing the chunks to use with your chips. Then there is the sauce that envelops them both. I like my chips chunky and not too saucy. Not that I am obsessed with food but I don't think you can consider design computing without chunks. It's the sauce I'm not sure about. The chunks of which I write are not of course those in your salsa picante but those postulated by Chase and Simon (1973) reflecting on good chess players; the chunks of knowledge with which an expert tackles a problem in their domain of expertise. The more knowledge an expert has of complex and large configurations of typical problem situations (configurations of chess pieces), the greater range of solutions the expert can bring a wider to a particular problem. Those with more chunks have more options and arrive at better solutions. In other words, good designs come from having plenty of big chunks available. There has been a wealth of research in the field of computer-supported collaborative work in the contexts of writing, office management, software design and policy bodies. It is typically divided between systems which support decision making (GDSS: group decision support systems) and those which facilitate joint work (CSCW: computer-based systems for co-operative work) (see Dennis et al. (1988) for a discussion of the distinctions and their likely convergence). Most implementations in the world of design have been on CSCW systems, few have looked at trying to make a group design decision support system (GDDSS?). Most of the work in CSCD has been grounded in the heritage of situated cognition - the assumption that collaborative design is an act that is intrinsically grounded in the context within which it is carried out, that is, the sauce in which we find ourselves swimming daily. By sauce, therefore, I am referring to anything that is not knowledge in the domain of expertise, such as modes of interaction, gestures, social behaviours.
