title	3DM: A three-dimensional modeler using a head-mounted display
source	Proceedings of the 1992 Symposium on Interactive 3D Graphics (Cambridge, Mass., March 29- April 1, 1992.), 135-138
summary	3dm is a three dimensional (3D) surface modeling program that draws techniques of model manipulation from both CAD and drawing programs and applies them to modeling in an intuitive way. 3dm uses a head-mounted display (HMD) to simplify the problem of 3D model manipulation and understanding. A HMD places the user in the modeling space, making three dimensional relationships more understandable. As a result, 3dm is easy to learn how to use and encourages experimentation with model shapes.

title	CoDraw “Graphical Constraints in CoDraw”
source	IEEE Workshop on Visual Languages, Seattle, WA, pp. 81-87
summary	Constraint based draw programs require users to understand and manage relationships between drawing elements. By establishing constraint relationships among elements the user effectively programs the drawing's behavior. This programming task requires a more sophisticated visual interface than conventional draw programs provide. Users must have available - in a convenient format - information about the structure of the constraints that determine the drawing's interactive edit behavior. This format must support editing and debugging. CoDraw is a constraint based drawing program that can be interactively extended by its users. This paper describes the CoDraw program and its programming interface.

title	ClearBoard: A Seamless Medium for Shared Drawing and Conversation with Eye Contact Systems for Media-Supported Collaboration
source	Proceedings of ACM CHI'92 Conference on HumanFactors in Computing Systems 1992 pp. 525-532
summary	This paper introduces a novel shared drawing medium called ClearBoard. It realizes (1) a seamless shared drawing space and (2) eye contact to support realtime and remote collaboration by two users. We devised the key metaphor: "talking through and drawing on a transparent glass window" to design ClearBoard. A prototype of ClearBoard is implemented based on the "Drafter-Mirror" architecture. This paper first reviews previous work on shared drawing support to clarify the design goals. We then examine three metaphors that fulfill these goals. The design requirements and the two possible system architectures of ClearBoard are described. Finally, some findings gained through the experimental use of the prototype, including the feature of "gaze awareness", are discussed.

title	From Sketches to Computer Images: A Strategy for the Application of Computers in Architectural Design

summary	The use of computer tools in architectural practice has been steadily increasing in recent years. Many architectural offices are already using computer tools, mostly for production tasks. Hardly any design is being done with the computer. With the new computer tools, architects are confronted with the challenge to use computers to express their design ideas right from conception. This paper describes a project made for a competition which recently took place in Spain. Sketches and computer models were the only tools used in designing this project. A variety of computer tools were used in different stages of this project: two dimensional drawing tools were used in the early stages, then a three-dimensional modeling program for the development of the design and for the production of final drawings, and a rendering program for final presentation images.

title	Case-Based Design support: A case study in architectural design
source	IEEE Expert 7(5): 14-20
summary	Archie, a small computer-based library of architectural design cases, is described. Archie helps architects in the high-level task of conceptual design as opposed to low-level tasks such as drawing and drafting, numerical calculations, and constraint propagation. Archie goes beyond supporting architects in design proposal and critiquing. It acts as a shared external memory that supports two kinds of design collaboration. First, by including enough knowledge about the goals, plans, outcomes, and lessons of past cases, it lets the designer access the work of previous architects. Second, by providing access to the perspectives of domain experts via the domain models, Archie helps architects anticipate and accommodate experts' views on evolving designs. The lessons learned about building large case-based systems to support real-world decision making in developing Archie are discussed.

title	Full-Scale Simulations as Tool for Developing Spatial Design Ability
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part C, pp. 7-10
summary	Spatial Design Ability has been defined as the capability to anticipate effects (psychological impressions on potential observers or users) produced by mental manipulation of elements of architectural or urban spaces. This ability, of great importance in choosing the appropriate option during the design process, is not specifically developed in schools of architecture and is partially obtained as a by-product of drawing, designing or architectural criticism. We use our Laboratory as a tool to present spaces to people so that they can evaluate them. By means of a series of exercises, students confront their anticipations with the psychological impressions produced in other people. For this occasion, we present an experience in which students had to propose a space for an exhibition hag in which architectural projects (student thesis) were to be shown. Following the Spatial Design Ability Development Model which we have been using for several years, students first get acquainted with the use of evaluation instruments for psychological impressions as well as with research methodology. In this case, due to the short period available, we reduced research to investigate the effects produced by the manipulation of only 2 independents variables: students manipulated first the form of the roof, walls and interiors elements, secondly, color and texture of those elements. They evaluated spatial quality, character and the other psychological impressions that manipulations produced in people. They used three dimensional scale models 1/10 and 1/1.

title	The Intelligent Sketch: Developing a Conceptual Model for a Digital Design Assistant
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 137-145

summary	The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.

title	Requirements of an Expert System for Design Studios
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 187-194
doi	https://doi.org/10.52842/conf.ecaade.1992.187
summary	The goal of this paper is to study problems of the transition from traditional architectural studio teaching to CAAD studio teaching which requires a CAAD expert system as studio tutor, and to study the behavior of the student in this new environment. The differences between the traditional and computerized studio teaching and the experiences in this field are explained referring to the requirements for designing time in relation to the expertise of the student in the application of a CAD program. Learning styles and the process of design in computerized and non-computerized studio teaching are discussed. Design studio requirements of the students in traditional studio environment while doing design works are clarified depending on the results of an empirical study which explained the relations between the tutor and the student while they were doing studio critiques. Main complaints of the students raised in the empirical study were the lack of data in the specific design problem area, difficulties of realization of ideas and thoughts, not knowing the starting point of design, having no information about the references to be used for the specific design task, having difficulties in the application of presentation techniques. In the concluding parts of the paper are discussed the different styles of teaching and their relation to the CAAD environment, the transformation of the instructional programs for the new design environment, the future expectations from the CAAD programs, properties of the new teaching environment and the roles of the expert systems in design studio education.

title	Structural Transformations (Basic Architectural Unit 6)
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 413-426
doi	https://doi.org/10.52842/conf.ecaade.1992.413
summary	While the teaching of the phenomenon of form as well as space is normally seen within an environment of free experimentation and personal expression, other directions prove to be worth of pursuit. The proposed paper represents such an exploration. The generation of controlled complexity and structural transformations have been the title of the project which forms the base of this paper. In it, the potential for creative development of the student was explored in such a way, that as in the sciences a process can be reproduced or an exploration utilized in further experimentation. The cube as a well proven B.A.U. or basic architectural unit has again been used in our work. Even a simple object like a cube has many properties. As properties are never pure, but always related to other properties, and looking at a single property as a specific value of a variable, it is possible to link a whole field of objects. These links provide a network of paths through which exploration and development is possible. The paper represents a first step in a direction which we think will compliment the already established basic design program.

summary	We already have the EEC, that is the European Economic Community. We have to build the CCE, that is the Common Cultural Europe. Architects and building engineers of any european country will be allowed to freely practise in any other country of the EEC. Of course, it is not only matter of coming down of the frontiers, of a greater labour mobility. Not even it will be enough that the university degree courses of the different countries agree to and put into effect the EEC common directives. They need rules and guidelines entering into the merits of practice: rules and guidelines which, rather than a legal and bureaucratic matter, must be the result of a common cultural and technical work, about clear and delimited questions of shared subjects, in which all the community countries be deeply concerned. Analogously, in the very field of research, the project "Human Capital and Mobility" has in view a greater european scientific and technological competitiveness, through an integration of human and material resources of different research centres, such as in shared-cost research projects and in concerted research actions. Such an integration is neither easy nor rapid. The political, social, cultural, technological peculiarities of the countries of the European Community certainly constitute an obstacle for the creation of a supernational cultural and technological pool. of common opportunities. These peculiarities, however, aren't only a restraint for the european community effort of unification and construction of shared goals, constraints, rules, methods, techniques, tools. They mean also a richness, an unrepeatable resourse: they are the result of a historical millenary stratification, which gave rise to urban and architectural contexts, to cultural and technological traditions it would be a serious mistake to waste.

title	Computer Aided Structural Design in Architectural Instruction
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 443-450
doi	https://doi.org/10.52842/conf.ecaade.1992.443
summary	In schools of architecture there is a tendency to associate the use of computers solely with the production of graphic images as part of the architectural design process. However, if the architecture is to work as a building it is also essential that technical aspects of the design are adequately investigated. One of the problem areas for most architectural students is structural design and they are often reluctant to use hand calculations to determine sizes of structural elements within their projects. In recent years, much of the drudgery of hand calculation has been removed from the engineer by the use of computers, and this has, hopefully, allowed a more thorough investigation of conceptual ideas and alternatives. The same benefit is now becoming available to architectural students. This is in the form of structural analysis and design programs that can be used, even by those having a limited knowledge of structural engineering, to assess the stability of designs and obtain approximate sizes for individual structural elements. The paper discusses how the use of such programs is taught, within the School of Architecture at Nottingham. Examples will be given of how they can assist students in the architectural design process. In particular, the application of GLULAM, a program for estimating sizes of laminated timber elements and SAND, a structural analysis and design package, will be described.

title	Portholes: Supporting Awareness in a Distributed Work Group
source	Proceedings of SIG CHI '92, pp. 541-547
summary	We are investigating ways in which media space technologies can support distributed work groups through access to information that supports general awareness. Awareness involves knowing who is “around”, what activities are occurring, who is talking with whom; it provides a view of one another in the daily work environments. Awareness may lead to informal interactions, spontaneous connections, and the development of shared cultures—all important aspects of maintaining working relationships which are denied to groups distributed across multiple sites. The Portholes project, at Rank Xerox EuroPARC in Cambridge, England, and Xerox PARC in Palo Alto, California, demonstrates that awareness can be supported across distance. A data network provides a shared database of image information that is regularly updated and available at all sites. Initial experiences of the system in use at EuroPARC and PARC suggest that Portholes both supports shared awareness and helps to build a “sense of community”.

title	Modeling Regulations and Intentions for Urban Development: The Role of Computer Simulation in the Urban Design Studio
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 201-212
doi	https://doi.org/10.52842/conf.ecaade.1992.201
summary	In this paper we present a strategy for modeling urban development in order to study the role of urban regulations and policies in the transformation of cities. We also suggest a methodology for using computer models as experimental tools in the urban design studio in order to make explicit the factors involved in shaping cities, and for the automatic visualization of projected development. The structure of the proposed model is based on different modules which represent, on the one hand, the rules regulating the physical growth of a city and, on the other hand, heuristics corresponding to different interests such as Real Estate Developers, City Hall Planners, Advocacy and Community Groups, and so on. Here we present a case study dealing with the Boston Redevelopment Authority zoning code for the Midtown Cultural District of Boston. We introduce a computer program which develops the district, adopting a particular point of view regarding urban regulation. We then generalize the notion of this type of computer modeling and simulation, and draw some conclusions about its possible uses in the teaching and practice of 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	Component-Based Spatial Reasoning
source	Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 103-111
doi	https://doi.org/10.52842/conf.acadia.1992.103
summary	The design process and ordering of individual components through which architecture is realized relies on the use of abstract "models" to represent a proposed design. The emergence and use of these abstract "models" for building representation has a long history and tradition in the field of architecture. Models have been made and continue to be made for the patron, occasionally the public, and as a guide for the builders. Models have also been described as a means to reflect on the design and to allow the design to be in dialogue with the creator. The term "model" in the above paragraph has been used in various ways and in this context is defined as any representation through which design intent is expressed. This includes accurate/ rational or abstract drawings (2- dimensional and 3-dimensional), physical models (realistic and abstract) and computer models (solid, void and virtual reality). The various models that fall within the categories above have been derived from the need to "view" the proposed design in various ways in order to support intuitive reasoning about the proposal and for evaluation purposes. For example, a 2-dimensional drawing of a floor plan is well suited to support reasoning about spatial relationships and circulation patterns while scaled 3-dimensional models facilitate reasoning about overall form, volume, light, massing etc. However, the common denominator of all architectural design projects (if the intent is to construct them in actual scale, physical form) are the discrete building elements from which the design will be constructed. It is proposed that a single computational model representing individual components supports all of the above "models" and facilitates "viewing"' the design according to the frame of reference of the viewer. Furthermore, it is the position of the authors that all reasoning stems from this rudimentary level of modeling individual components. The concept of component representation has been derived from the fact that a "real" building (made from individual components such as nuts, bolts and bar joists) can be "viewed" differently according to the frame of reference of the viewer. Each individual has the ability to infer and abstract from the assemblies of components a variety of different "models" ranging from a visceral, experiential understanding to a very technical, physical understanding. The component concept has already proven to be a valuable tool for reasoning about assemblies, interferences between components, tracing of load path and numerous other component related applications. In order to validate the component-based modeling concept this effort will focus on the development of spatial understanding from the component-based model. The discussions will, therefore, center about the representation of individual components and the development of spatial models and spatial reasoning from the component model. In order to frame the argument that spatial modeling and reasoning can be derived from the component representation, a review of the component-based modeling concept will precede the discussions of spatial issues.

title	Spatial Perception in Virtual Environments : Evaluating an Architectural Application
source	University of Washington
summary	Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments. This was a marvelous discovery for me because I had found a viable use for virtual environments which could be immediately beneficial to architecture, my shared area of interest. It would be further beneficial to architecture in that the virtual interface equipment I would be evaluating at the H.I.T.L. happens to be relatively less expensive and more practical than other configurations such as the "Walkthrough" at the University of North Carolina. The set-up at the H.I.T.L. could be easily introduced into architectural firms because it takes up very little physical room (150 square feet) and it does not require expensive and space taking hardware devices (such as the treadmill device for simulating walking). Now that the potential for using virtual environments in this architectural application is clear, it becomes important to verify that this tool succeeds in accurately representing space as intended. The purpose of this study is to verify that the perception of spaces is the same, in both simulated and real environment. It is hoped that the findings of this study will guide and accelerate the process by which the technology makes its way into the field of architecture.

title	Genetic Algorithms
source	Scientific America, July 1992
summary	Living organisms are consummate problem solvers. They exhibit a versatility that puts the best computer programs to shame. This observation is especially galling for computer scientists, who may spend months or years of intellectual effort on an algorithm, whereas organisms come by their abilities through the apparently undirected mechanism of evolution and natural selection. Pragmatic researchers see evolution's remarkable power as something to be emulated rather than envied. Natural selection eliminates one of the greatest hurdles in software design: specifying in advance all the features of a problem and the actions a program should take to deal with them. By harnessing the mechanisms of evolution, researchers may be able to "breed" programs that solve problems even when no person can fully understand their structure. Indeed, these so-called genetic algorithms have already demonstrated the ability to made breakthroughs in the design of such complex systems as jet engines. Genetic algorithms make it possible to explore a far greater range of potential solutions to a problem than do conventional programs. Furthermore, as researchers probe the natural selection of programs under controlled an well-understood conditions, the practical results they achieve may yield some insight into the details of how life and intelligence evolve in the natural world.

title	A Graphical Feedback Model for Computerized Energy Analysis during the Conceptual Design Stage
source	Texas A&M University
summary	During the last two decades, considerable effort has been placed on the development of building design analysis tools. Architects and designers have begun to take advantage of computers to generate and examine design alternatives. However, because it has been difficult to adapt computer technologies to the visual orientation of the building designer, the majority of computer applications have been limited to numerical analysis and office automation tasks. Only recently, because of advances in hardware and software techniques, computers have entered into a new phase in the development of architectural design. haveters are now able to interactively display graphics solutions to architectural related problems, which is fundamental to the design process. The majority of research programs in energy efficient design have sharpened people's understanding of energy principles and their application of those principles. Energy conservation concepts, however, have not been widely used. A major problem in the implementation of these principles is that energy principles their applications are abstract, hard to visualize and separated from the architectural design process. Furthermore, one aspect of energy analysis may contain thousands of pieces of numerical information which often leads to confusion on the part of designers. If these difficulties can be overcome, it would bring a great benefit to the advancement of energy conservation concepts. This research explores the concept of an integrated computer graphics program to support energy efficient design. It focuses on (1) the integration of energy efficiently and architectural design, and (2) the visualization of building energy use through graphical interfaces during the conceptual design stage. It involves (1) the discussion of frameworks of computer-aided architectural design and computer-aided energy efficient building design, and (2) the development of an integrated computer prototype program with a graphical interface that helps the designer create building layouts, analyze building energy interactively and receive visual feedbacks dynamically. The goal is to apply computer graphics as an aid to visualize the effects of energy related decisions and therefore permit the designer to visualize and understand energy conservation concepts in the conceptual phase of architectural design.

title	A computer-based framework for analyzing and deriving the morphological structure of architectural designs
source	University of Michigan
summary	An approach to the acquisition and utilization of knowledge about the morphological structure of notable orthogonal building plans and other two-dimensional compositions is formulated and tested. This approach consists of two levels of abstraction within which the analysis and comparison of existing designs and the derivation of new designs can be undertaken systematically and efficiently. Specifically, the morphological structure of orthogonal building plans and other two-dimensional compositions is conceived as a language defined by shape grammar and architectural grammar corresponding to the geometric and spatial structures of the compositions. Lines constitute the shape grammar and walls and columns the architectural grammar. A computer program named ANADER is designed and implemented using the C++ object-oriented language to describe feasible compositions. It is argued that the gap between morphological analysis and synthesis is bridged partially because the proposed framework facilitates systematic comparisons of the morphological structures of two-dimensional orthogonal compositions and provides insight into the form-making process used to derive them. As an analytical system, the framework contributes to the generation of new and the assessment of existing morphological knowledge. Specifically, it is demonstrated that it is feasible to specify an existing architectural design by a set of universal rule schemata and the sequence of their application. As a generative system, the framework allows many of the tasks involved in the derivation of two-dimensional orthogonal compositions to be carried out. As well, it promotes the use of analytical results. In conclusion, it is argued that the proposed computer-based framework will provide the research and the educator with increasing opportunities for addressing persistent architectural questions in new ways. Of particular interest to this author are questions concerning the decision-making activities involved in form- and space-making as well as the description, classification, and derivation of architecutural form and space. It is suggested that, at least in reference to the cases examined, but probably also in reference to many other morphological classes, these and other related questions can be addressed systematically, efficiently, and fruitfully by using the proposed framework.
