title	USER PARTICIPATION IN DESIGN: TECHNIQUES FOR DIALOGUE
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 17-24
summary	Many projects in which users participate in the design process are merely examples of professionals communicating their ideas to their clients. Conventional computer systems can be powerful tools for helping designers to present design informations to lay audiences, but when combined with computer modelling and simulation, they create opportunities for users to construct their own sequences of images and thus explore designs from their own viewpoint. Building on extensive experience of traditional methods of user participation, this paper explores the use of narratives to create dialogues between users, designers and computers. The concept of "design stories" as a route to fully shared creativity is explained. The paper also argues that this approach is needed to bring into focus design issues that cannot be described or resolved by computer modelling alone.

title	A Computational Framework for Supporting Creative Architectural Design
source	New York: John Wiley & Sons, 1992. pp. 17-34 : ill. includes Bibliography
summary	Design can be considered a process leading to the definition of a physical form that achieves a certain predefined set of performance criteria. The process comprises three distinct operations: (1) Definition of the desired set of performance criteria (design goals); (2) generation of alternative design solutions; (3) evaluation of the expected performances of alternative design solutions, and comparing them to the predefined criteria. Difficulties arise in performing each one of the three operations, and in combining them into a purposeful unified process. Computational techniques were developed to assist each of the three operations. A comprehensive and successful computational design assistant will have to recognize the limitations of current computational techniques, and incorporate a symbiosis between the machine and the human designer. This symbiosis comprises allocating design tasks between the designer and the computer in a manner that is most appropriate for the task at hand. The task allocation must, therefore, be done dynamically, responding to the changing circumstances of the design process. This report proposes a framework for such a symbiotic partnership, which comprises four major components: (1) User interface and design process control; (2) design goals; (3) evaluators; (4) database

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

title	A functional approach to realizing decision support systems in technical regulation management for design and construction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Technical building standards defining the quality of buildings, building products, building materials and building processes aim to provide acceptable levels of safety, health, usefulness and energy consumption. However, the logical consistency between these goals and the set of regulations produced to achieve them is often hard to identify. Not only the large quantities of highly complex and frequently changing building regulations to be met, but also the variety of user demands and the steadily increasing technical information on (new) materials, products and buildings have produced a very complex set of knowledge and data that should be taken into account when handling technical building regulations. Integrating knowledge technology and database technology is an important step towards managing the complexity of technical regulations. Generally, two strategies can be followed to integrate knowledge and database technology. The main emphasis of the first strategy is on transferring data structures and processing techniques from one field of research to another. The second approach is concerned exclusively with the semantic structure of what is contained in the data-based or knowledge-based system. The aim of this paper is to show that the second or knowledge-level approach, in particular the theory of functional classifications, is more fundamental and more fruitful. It permits a goal-directed rationalized strategy towards analysis, use and application of regulations. Therefore, it enables the reconstruction of (deep) models of regulations, objects and of users accounting for the flexibility and dynamics that are responsible for the complexity of technical regulations. Finally, at the systems level, the theory supports an effective development of a new class of rational Decision Support Systems (DSS), which should reduce the complexity of technical regulations and restore the logical consistency between the goals of technical regulations and the technical regulations themselves.

title	Design Modelling and Design Presentation From a Computer-Generated Image Towards a Multi-user Design System
doi	https://doi.org/10.52842/conf.ecaade.1992.137
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 137-144
summary	CAD systems regularly offer new techniques for the presentation of design proposals like computer-generated (stereo-) images, animations, holography and virtual reality. These techniques are mainly used for the presentation of a final design or for the presentation of buildings that have already been constructed. As in the course of time the quality of the CAD systems and their users have improved enormously, it is also possible to use these systems for the evaluation of several temporary design proposals during the design process. Since 'beautiful pictures' and 'wonderful animations' have already shown their great value when presenting a design, it is sometimes as if CAD systems are considered suitable for this propose only. Even new techniques like virtual reality systems seem to be valued only through the 'tinted glasses' of the presentation capabilities. Hardly any attention is paid to the possibilities that these new techniques offer as an instrument to support modelling and evaluation during the design process. This article will outline the results of research and development in the field of virtual reality. Virtual reality systems are based on the combination of a number of already existing presentation techniques like photo-realistic images, stereo images and real time animations. The added value of this type of CAD system is determined by the use of a new type of user interface. In effect this interface consists of sensors that register how its user moves and looks around. Through this, and by using a so- called 'eye phone' (comparable to stereo headphones for sound) the user, with some imaginative powers, thinks he is standing in the environment that he modelled, or in front of his building design. After this we will first sketch the outlines of some presentation techniques, that can also be found in a virtual reality system. Special attention will be paid to some specific characteristics of these techniques themselves. Next, a more detailed description will be given of virtual reality systems, focusing on the system that is being developed at Calibre itself.

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 57-60
summary	The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title	Personal Working Styles in the CMD Studio
doi	https://doi.org/10.52842/conf.ecaade.1992.451
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 451-472
summary	Normative and problem-solving approaches of architectural design ignore the personality aspects of the designing activity. Every architect approaches projects according to her/his own strategies and tactics. Usually they do not conform to the prescriptive models of design theoreticians. Computer aided design tools should be adapted to their utility within the strategies and tactics of each and every architectural student. We are testing the usefulness of CAAD tools developed by others or ourselves and identifying the needs for missing tools. It is already clear that many CAAD tools reflect the point of view of the programmer about strategies and tactics of designing and that they do not take into account the idiosyncrasies of the end user. Forcing the tools on students breeds the risk of fostering repulsion against ill-adapted tools, and consequently against CMD. Our research group pursues empirical research on working styles of designing by practising architects within the frame of a personality theory of actions. The results indicate that there are three main directions for designing strategies. If we want to take into account the real-world behaviour in design practice within architectural education, this implies the diversification of the exercises we offer to the students in threefold, corresponding with the three directions. To this, we add the didactic options of complementation, compensation and support, depending on what we know about the strong or weak points of the students involved. We have started proposing choices for the exercises of our design morphology studio. Students are offered approaches and tools we consider best adapted to their own working

title	Working with prototypes: from cad to flexible tools for integrated building design
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The formulation of design knowledge as concepts, goals and rules cannot be captured in fixed and valid statements. The dynamic modelling of concepts and goals is, on the contrary, part of the design process itself. Tools that effectively support architects in their design should therefore never use predefined mechanisms, but must be definable interactively according to design specifications. We propose the concept of prototypes as a cognitive model to represent and structure design knowledge. Prototypes incorporate an individual view of design in a synthetic and organizational model for a defined area of interest. They actively control and guide design processes in supporting the organizational concepts for solutions. The a+Tool implements these concepts on the basis of a modelling language. It provides a dynamic toolkit and user interface to support design as well as knowledge modelling.

title	Gardeners and Gurus: Patterns of Cooperation among CAD Users Perspectives on the Design of CollaborativeSystems
source	Proceedings of ACM CHI'92 Conference on Human Factors in ComputingSystems 1992 pp. 107-117
summary	We studied CAD system users to find out how they use the sophisticated customization and extension facilities offered by many CAD products. We found that users of varying levels of expertise collaborate to customize their CAD environments and to create programmatic extensions to their applications. Within a group of users, there is at least one local expert who provides support for other users. We call this person a local developer. The local developer is a fellow domain expert, not a professional programmer, outside technical consultant or MIS staff member. We found that in some CAD environments the support role has been formalized so that local developers are given official recognition, and time and resources to pursue local developer activities. In general, this formalization of the local developer role appears successful. We discuss the implications of our findings for work practices and for software design.

title	Issues and Experiences Designing and Implementing Two Group Drawing Tools
source	Readings in Groupware, 609-620
summary	Groupware designers are now developing multi-user equivalents of popular paint and draw applications. Their job is not an easy one. First, human factors issues peculiar to group interaction appear that, if ignored, seriously limit the usability of the group tool. Second, implementation is fraught with considerable hurdles. This paper describes the issues and experiences we have met and handled in the design of two systems supporting remote real time group interaction: GroupSketch, a multi-user sketchpad; and GroupDraw, an object-based multi-user draw package. On the human factors side, we summarize empirically-derived design principles that we believe are critical to building useful and usable collaborative drawing tools. On the implementation side, we describe our experiences with replicated versus centralized architectures, schemes for participant registration, multiple cursors, network requirements, and the structure of the drawing primitives.

title	A Building Design and Evaluation System
source	New York: John Wiley & Sons, 1992. pp. 195-211 : ill. table. includes bibliography
summary	Within the field of architectural design there is a growing awareness of imbalance among the professionalism, the experience, and the creativity of the designers' response to the up-to-date requirements of all parties interested in the design process. The building design and evaluating system COSMOS makes it possible for various participants to work within their own domain, so that separated but coordinated work can be done. This system is meant to organize the initial stage of the design process, where user-defined functions, geometry, type of construction, and building materials are decided. It offers a tool to design a building to calculate a number of effects and for managing the information necessary to evaluate the design decisions. The system is provided with data and sets of parameters for describing the conditions, along with their properties, of the main building functions of a selection of well-known building types. The architectural design is conceptualized as being a hierarchy of spatial units, ranking from building blocks down to specific rooms or spaces. The concept of zoning is used as a means of calculating and directly evaluating the structure of the design without working out the details. A distinction is made between internal and external calculations and evaluations during the initial design process. During design on screen, an estimation can be recorded of building costs, energy costs, acoustics, lighting, construction, and utility. Furthermore, the design can be exported to a design application program, in this case AutoCAD, to make and show drawings in more detail. Through the medium of a database, external calculation and evaluation of building costs, life-cycle costs, energy costs, interior climate, acoustics, lighting, construction, and utility are possible in much more advanced application programs

title	COMMUNICATING WITH LAYPEOPLE
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 25-32
summary	The purpose of the architect's tools is, as generally stated, to help the architects themselves to develop and visualize their spatial ideas and intentions. But the tools can also be used to communicate with other groups of professionals and with laypeople. This paper deals with the question how the choice of tools can effect the communication between laypeople and architects. It also stresses the need of combining different media in order to create the best conditions for user's participation. If the users will be able to influence the planning of an environment they must understand the "language" of the medium and have the ability to use it themselves. Models on diverse scales, and first of all the scale 1:1, fulfil these demands better than drawings. There are distinct limitations of the full-scale model, when it comes to give the users a comprehension of the entire mock-up, and thus models on smaller scales are required. Limitations of both full-scale and small scale models concerning visualizing the exterior and the building's interaction with the environment could possibly be worked out with the help of computer technique.

title	An Approach to 3D Conceptual Modelling
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This article presents a 3D user interface required by the development of conceptual modeling. This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

title	A FRAMEWORK FOR COMPUTER-SUPPORTED COLLABORATION IN ARCHITECTURAL DESIGN
source	University of Michigan
summary	The development of appropriate research frameworks and guidelines for the construction of software aids in the area of architectural design can lead to a better understanding of designing and computer support for designing (Gero and Maher 1997). The field of research and development in computer-supported collaborative architectural design reflects that of the early period in the development of the field of computersupported cooperative work (CSCW). In the early 1990s, the field of CSCW relied on unsystematic attempts to generate software that increases the productivity of people working together (Robinson 1992). Furthermore, a shift is taking place by which researchers in the field of architecture are increasingly becoming consumers of rather than innovators of technology (Gero and Maher . In particular, the field of architecture is rapidly becoming dependent on commercial software implementations that are slow to respond to new research or to user demands. Additionally, these commercial systems force a particular view of the domain they serve and as such might hinder rather than help its development. The aim of this dissertation is to provide information to architects and others to help them build their own tools or, at a minimum, be critical of commercial solutions.

source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Computer vision offers the ability to transform digitized drawings into documents that can be used with computer systems. Recognition of digitized drawings can occur at the levels of (a) geometric elements, (b) building elements, and (c) spatial articulation. The last two levels apply not only to digitized images but also to computer-produced ones. The enormous burden placed on the user for inputting and manipulating CAD drawings suggests that automated recognition can add to the capabilities of CAD by making the computer more flexible with respect to inputting design information and more responsive to the actual concerns of the designer.

summary	Reasoning is influenced by our perception of the environment. New aspects of our environment help to provoke new thoughts. Thus, changes of what is perceived can be assumed to stimulate the generation of new ideas, as well. In CAD, computerized three-dimensional models of physical entities are produced. Their representation on the monitor is determined by our viewing position and by the rendering method used. Especially the wire-frame representations of views lend themselves to a variety of readings, due to coincident and intersecting lines. Methods by which wire-frame views can be processed to extract the shapes that they contain have been investigated and developed. The extracted shapes can be used as a base for the generation of derived entities through various operations that are called Reinterpretation Operations. They have been implemented as a prototypical extension (named Reint-Ops) to an existing modeling shell. ReintOps is a highly interactive exploratory CAD tool, which allows the user to customize criteria and factors which are used in the reinterpretation process. This tool can be regarded as having a potential to support conceptual design investigations.

title	Multiple Operative and Interactive Modes in Knowledge-Based Design Systems
source	New York: John Wiley & Sons, 1992. pp. 125-143 : ill. includes bibliography
summary	A conceptual basis for the development of an expert system which is capable of integrating various modes of generation and evaluation in design is presented. This approach is based upon two sets of reasoning processes in the design system. The first enables a mapping between design requirements and solution descriptions in a generative mode of design; and the second enables a mapping between solution descriptions and performance evaluation in an evaluative and predictive mode. This concept supports a formal framework necessary for a knowledge-based design system to operate in a design partnership relation with the designer. Another fundamental concept in expert systems for design, dual direction interpretation between graphic and textual modes, is presented and elaborated. This encoding of knowledge behind the geometrical representation can be achieved in knowledge- based design systems by the development of a 'semantic interpreter' which supports a dual direction mapping process employing a geometrical knowledge, typological knowledge and evaluative knowledge. An implemented expert system for design, PREDIKT, demonstrates these concepts in the domain of kitchen design. It provides the user with a choice of alternative modes of interaction, such as: a 'design critic' for the evaluation of a design, a 'design generator' for the generation of a design, or a 'design critic-generator' for the completion of partial solutions

title	Data Modeling Needs of Life Safety Code (LSC) Compliance Applications
doi	https://doi.org/10.52842/conf.acadia.1992.177
source	Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 177-185
summary	One of the most complex code compliance issues originates from the conformance of designs to Life Safety Code (NFPA 101). The development of computer based code compliance checking programs attracted the attention of building researchers and practitioners alike. These studies represent a number of approaches ranging from CAD based procedural approaches to rule based, non graphic ones, but they do not address the interaction of the rule base of such systems with graphic data bases that define the geometry of architectural objects. Automatic extraction of the attributes and the configuration of building systems requires 11 architectural object - graphic entity" data models that allow access and retrieval of the necessary data for code compliance checking. This study aims to specifically focus on the development of such a data model through the use of AutoLISP feature of AutoCAD (Autodesk Inc.) graphic system. This data model is intended to interact with a Life Safety Code rule base created through Level5-Object (Focus Inc.) expert system. Assuming the availability of a more general building data model, one must define life and fire safety features of a building before any automatic checking can be performed. Object oriented data structures are beginning to be applied to design objects, since they allow the type versatility demanded by design applications. As one generates a functional view of the main data model, the software user must provide domain specific information. A functional view is defined as the process of generating domain specific data structures from a more general purpose data model, such as defining egress routes from wall or room object data structure. Typically in the early design phase of a project, these are related to the emergency egress design features of a building. Certain decisions such as where to provide sprinkler protection or the location of protected egress ways must be made early in the process.
