title Psychology of Early Design in Architecture
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Lately there has been a good deal of emphasis on the early stages of the design process, particularly by developers of computer aids and quantitative design models for both evaluation and generation of designs in a variety of domains. Yet, there is little understanding of the early design-process. While the early design process as manifested by human designers need not be the sole basis of the description of this phase, it certainly represents and important kernel of knowledge, especially for those who are interested in developing models, systems or merely interfaces for such systems. This paper focuses on the characterization of the psychology of the early design phase in architecture. It is described in terms of the general design strategies and problem solving tactics used; and is contrasted against some of the process characteristics that

summary Beginning in 1993, small groups of students of architectural design at different institutions around the world participated in collaborative design projects using a variety of tools, including CAD, Internet and teleconferencing. This programme, known as the "Virtual Design Studio" (VDS), allows students to work collectively with colleagues from different cultures and climates who are thousands of kilometres and in different time zones. Most recently, in February 1994, four institutions in N. America, one in Europe, and one in S E Asia participated in VDS’94. This paper explains the operation of the VDS and explores the future of the VDS as a potential tool for architectural design education. In particular, we review what we have learned in employing computer tools to extend the teaching in design studios into a "virtual" experience.

title THe "Allots" Model: A PC-Based Approach to Demand Distribution for Siting and Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper reports on the development and application of ALLOT: a user-friendly, flexible computer model which has been designed to help governmental jurisdictions and private landowners throughout the world to achieve more economically efficient and environmentally sound land use and development patterns in a short period of time. ALLOT has the potential to drastically change the way that land use planning is conducted, since it has the capability to allow theincorporation of a wide variety of previously ignored environmental characteristics and up-to-date land use patterns. ALLOT, which is written in the SAS programming language, contains twomajor parts. The first part employs a GIS database to conduct land suitability analyses for the area. It then produces maps showing the most suitable areas for various land use types. The second part appears to be unique in the field of computerized land use planning models. It combines the results of the suitability analysis with forecasted demand for various land use types to produce "optimum" future land use patterns. The model is capable of quickly analyzing a wide variety of forecasts, allowing easy comparison of different growth scenarios; and it can also be modified to reflect community goals and objectives, such as protection of wildlife habitat orattraction of industry. The flexibility, combined with the fact that it runs on any IBM-compatible PC (286 or higher), make it a powerful land use planning tool. The model has been successfully applied in two "real world" situations. First, three alternative future land use patterns were developed for a rural lakeside area. The area had rural characteristics and was lacking infrastructure, but a large influx of people was expected as the lake was filled. The success of this effort led to decision to test it´s use as a method for facility siting (using landfill siting as an example).

title GIS: Science or Tool - The Built Environment Perspective
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper attempts to locate GIS in the context of the built environment professions, rather than in the context of computer science, recognizing the integrated but limiting approach of viewingGIS from a strictly computer / spatial science perspective. The paper reviews the conflicts and tensions appearing in the GIS debate seeing them as reflecting the differences between the perceptions and interests of software developers and those of the professions. The "spatial science versus professional tool" dilemma is therefore critically assessed. Science is identified as the dominant paradigm within which GIS development has taken place. This encompasses the emphasis on GIS as spatial science; the interest in particular forms of spatial analysis; a narrow approach to the idea of information; the debate about the appropriate emphasis on the location for GIS in undergraduate education. The interests and activities of the professions cannot be encompassed within the pre-existing science paradigm. The paper identifies the interest the professions have had in broad geographical issues (as distinct from narrow spatial issues). It recognizes the different conventions and procedures used in recording and using geographical information, not all of them objective or scientific. It views the computer, not as a "scientific engine", but as a modern medium for representing and analyzing information. This includes storage and analysis, both internally (algorithmic manipulation) and outside (qualitative manipulation, beyond formal -"computer"- logic). This approach suggests a framework for research of a nature more sympathetic to the needs of the built environment professions in particular and an agenda which would include an examination of: (i) the conventions and procedures used in the professions to collect, store and process information and how these translate to computer technology; (ii) the types of software used and the way procedures may be accommodated by combining and integrating packages; (iii) the dynamism of GIS development (terms such as "dedicated", "mainframe", "PC-based", "distributed", "pseudo-", etc. are identified as indicativeof the need for professions-based approaches to GIS development); (iv) a critique of "information" (modelling of information flows within the professions, may yield valuable insights into the (modelling of information flows within the professions , may yield valuable insights into the similarity of requirements for a variety of "workplace scenarios").

title ArchiWAIS: A Multimedia-Based Architectural Information System for Teaching and Learning Architectural History and Theory
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 161-169
doi https://doi.org/10.52842/conf.acadia.1994.161
summary Currently, there is a debate among architectural educators regarding the use of computers in the curricula. At present, computers are used for design purposes, and there is limited use in other areas of the curricula. This paper explores an instructional tool developed specifically for the teaching and learning of architectural history and theory, and since these courses are main components of any architectural curricula, using this tool can have a great impact on architectural education in general. The tool, called ArchiWAIS, is a multimedia-based architectural information system that utilizes emerging computer technologies such as multimedia, hypermedia, and telecommunications. As a multimedia system ArchiWAIS provides effective ways of handling various architectural media-text, images, architectural drawings and diagrams, three-dimensional models, animation and sound. ArchiWAIS as a distributed hypermedia system also provides multiple ways to search multimedia databases and browse through multimedia. ArchiWAIS is a WAIS (Wide-Area Information Server) client and has access to architectural databases specially constructed for this experimental project as well as general WAIS databases. ArchiWAIS is one of two subsystems of ArchiTOUR, an educational system currently under development. While ArchiWAIS searches and collects a variety of architectural information, HyperTOUR, the other subsystem of ArchiTOUR, can be used for presenting and learning a specific subject in architectural history and theory. A future extension of ArchiTOUR will be the integration of other curricula into the system, in essence, creating a common ground among architectural courses.

title Variety in Design
source Systems Research, vol. 11, no 3
summary It is argued that creativity might be amplified through the co-operative sharing of brain power (in contrast to Ashby's amplification of intelligence by restricting attention to the problem). This argument is extended to the act of design (seen as the making of the new), where it is proposed that the nature of the computer is to encourage co-operative sharing because, by making perfect copies, it denies ownership. This, in turn, underpins the processes of collaging and transformation that so suit the computer. A means of using the computer is proposed in which both sharing and distortion are encouraged, so that the new may be made while the individual's sense of creation and of origination is respected. Possible questions and difficulties are raised. Some are resolved.1

title Recognition and Retrieval in Visual Architectural Databases
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The development of visual architectural databases is heavily constrained by two technically, practically and conceptually intricate problems, input and retrieval. Input of visual images indifferent forms and from a variety of sources results into computer documents which can only be reproduced and disseminated. Any other use requires extensive annotation of the images with respect to indexing terms and other conceptual structures that make the images identifiable. The bulk of even modest visual databases and the complexity of the images and of the conceptual schemes means that interactive processing is labour-intensive and unreliable. Retrieval also relies on the same processes of annotation and indexing, which make possible the correlation of database contents with user queries. The paper presents the potential of automated recognition for inputting architectural floor plans into visual databases. An optically digitized image is segmented and each segment recognized as an instance of a building element (wall, door, window, etc.). The array ofrecognized elements is then controlled for recognition and segmentation errors. Further processing allows identification of spaces in the floor plan and of their interrelationships. The output of the process is a symbolic array that is much more compact than the original pixel array and also amenable to abstract and /or specific user queries, such as "How many doors are there in the floorplan" or "Which floor plans contain a double loaded corridor". These queries can be input verbally or graphically. Identification of building and spatial elements in a floor plan also allows use of vocabulary control in retrieval: user queries are checked against a thesaurus of architectural terms for accuracy and precision. The user is then presented with options for the improvement of the query before proceeding with identifying relevant entries in the database. Use ofvocabulary control as a search intermediary improves performance and reduces user frustration by making explicit the relevance of a query.

title Geographical Information Systems and Decision Support for Envi-ronmental Management
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The growing requirement for spatial decision support systems in Urban and Regional Management is pointed out. This has come about due to the increasing complexity of modern human activities, the increase in awareness of the negative consequences of mankind's technological development on the environment, and also due to the need to respect new regulations and legislation regarding environmental impacts. Such spatial decision support systems need to manipulate and analyze a wide variety of spatially referenced information, frequently in large quantities. Geographical Information Systems are now the chosen means for supporting such information, but in order to arrive at decisions further analysis modules and decision aids frequently need to be linked to them, or integrated with them. Linking multicriteria decision aid with spatial analysis is one way in which spatially referenced information can be used to arrive at decisions in situations where there are many and conflicting criteria. Examples of applications of these ideas to real management problems, including waste management, river management and site management are used to show how spatial information can now be manipulated to aid decisions, and to arrive at some of the design requirements for more flexible and applicable decision support systems. The merits and disadvantages of several different approaches to design and implementation of decision support systems, especially from the users point of view, are discussed.

summary This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title Informing multimedia: a sensitive interface to data for construction design professionals
source Design Studies 1994 pp. 285-316
summary 'Design Dialogues: one' was the first in an occasional series of discussion meetings on design theory sponsored by the Design Research Society. The objective of the meeting was to explore the reasons for the apparent lack of progress in design research over the last decade and in particular whether the search for an atemporal, acultural, domain independent theory of design is a reasonable or realistic goal. The meeting was held on the 17th of May at the Department of Computer Science, University College London and attracted more than 40 participants from a wide variety of disciplines including the arts, architecture, computer science, engineering and business studies.In an attempt to continue the debate in the wider design research community, we have produced the following summary of the presentations and discussion period together with some concluding remarks. While we have made every effort ensure that summaries of the speakers presentations and the discussion are accurate, readers should be aware that they are based on notes taken during the meeting itself and consequently reflect a particular interpretation of the proceedings. However, for those who wish to follow up the ideas presented by the speakers in more detail, we have included a short list of references to relevant work at the end of this meeting summary.

title Opening Doors at Harvard's Graduate School of Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Design communication has many forms and employs a wide array of references. Design pedagogy uses a rich body of sources and is informed by deep communication between faculty and student. Advancing technology for distribution and manipulation of digital design media and a pervasive computer network at the Harvard Graduate School of Design provide an ideal environment for investigating new methods of access to design resources. A research initiative called the DOORS project (Design-Oriented On-line Resource System) will make a variety of design reference materials available over the GSD's computer network Potentially, DOORS will provide access to: - the Frances Loeb Library's visual and special collections; - slides, drawings, photographs, videos; - private faculty slide collections; - maps and geographic information systems of text, numeric and other visual databases of three- dimensional computer models; - computer-generated animations and digital video segments with sound of multimedia projects. As early pilot versions of DOORS are released, faculty and students will gather visual information for study and modification, analyze images and models, compare and link design documentation in different formats, develop lectures and make presentations from computers in offices, classrooms, and studio work areas. Emphasis will be placed on flexibility, as this particular tool's success will hinge on its ability to respond to different approaches to design and instruction. DOORS proposes to offer three modalities, browsing, composition and presentation, to enable searching, organizati-on, and display. Using established library standards for record format, subject access and keyword indexing, browsing will offer flexible and diverse search criteria. Composition will provide tools for linking, annotation and manipulation of assembled materials. Individual presentations will be viewed in classrooms, studios or offices. A pilot project to assemble some of the basic technology and expertise required is currently under way. The objective of the pilot is to deliver a slice of material over the GSD's local area network in order to raise awareness of the tool's potential among faculty and students, to evaluate its effectiveness, and to formulate technical specifications for later project phases.

title Towards Hybrid Technologies for Urban Design: Balancing Reliability, Power and Speed in Decision Support
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper constructs a theory of decision support system design, based on the three independent concepts of reliability, power and speed borrowed from epistemology. We say that a system is reliable if a large part of its performance is useful or correct, that it is powerful if it performs in a useful way in a variety of situations of interest, and that it is fast if its behaviour is consistently dynamic. An arithmetic calculator, for example, is more reliable than a mathematician, but the latter is more powerful. A programming language is as reliable as a calculator, but the calculator is faster. We use this framework to argue that a successful deployment of decision support technology must take into account the balance between reliability power and speed. We illustrate this approach with the case of a hybrid system for studying urban transportation issues in the Greater Barcelona Region based on land use, contrasting it with more conventional tools such as traditional geographic information systems or traffic analysis software. The hybrid system is shown to sacrifice the reliability and speed characteristic of commercially available software for a powerful set of computational tools developed specifically for the problem at hand. This tradeoff process is formalized using an analysis based on second-order reliability, power and speed concepts. We show that micro-level sacrifices of one of these properties are often inversely correlated with the same characteristics at the macro level. For example, the relatively slow performance of in-house software components on a given project can result in a high level of dynamism in addressing several related projects. We extend the design theory outlined above to a methodology for characterizing decision support systems in general, and argue that the hybrid technologies approach is more likely to result in systems reflecting the user's domain knowledge and skills.

title The Symbolic Dimensions of Workplace Evaluations
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Post-Occupancy Evaluation (POE) techniques have been used during the past twenty years in a variety of workplace settings to measure specific occupant responses to the physical dimensions of the office environment. Typically, these measures have been used by environmental researchers and designers to improve instrumental aspects of the workplace, such as increased levels of occupant satisfaction with lighting, temperature, privacy, and office configuration. A growing body of evidence has begun to suggest that while instrumental approaches to workplace evaluation have produced improvements in specific office conditions, overall levels of worker satisfaction and perceptions of the general character of the office setting remain low. It has also been suggested that future pressures for reconfiguring the workplace -- increased use of individual communication technologies, working away from the office setting, rapid and continual changes in working patterns - will exacerbate these negative perceptions of workers. This paper will suggest ways in which POEs can be employed to identify and measure the less tangible aspects of office setting and how this information can be used to enhance the designers ability to address the cultural and social dimensions of the workplace. The central thesis of this paper is that POE theories and research methodologies must be focused on the symbolic dimensions of the workplace (i.e., office image, organizational culture, work purpose) in order to understand the ways in which the environment contributes to specific improvements in worker productivity, health, and satisfaction. Data will be presented from the author's recent POE studies of governmental offices and published supporting material found in Environment and Behaviour and The Journal of Architectu-ral and Planning Research. The author has conducted evaluation and programming studies for a number of private and governmental client groups in both office and health-care settings during the past fifteen years, and he will use evidence from this body of work as well as parallel studies of colleagues to support the thesis of the paper.

title Computer-aided extraction of morphological information from architectural drawings
source University of Michigan
summary Along with the popularization of Computer-Aided Design (CAD), it has been becoming increasingly necessary and desirable for a computer to recognize engineering drawings and diagrams. Methods exist for inputting and recognizing such engineering drawings and diagrams. This is primarily because they are drawn to conform to specific standards. In contrast, architectural drawings are not prepared in accordance to existing standards. Hence, the problem of reading, recognizing, and extracting morphological information from them automatically remains unsolved. It is this problem that this study focuses on. The research undertaken by this author has three distinct but interrelated objectives. The first objective is to design, implement, and test a computer-based framework which allows its user to extract automatically the geometric and/or architectural structures of a two-dimensional plan. The second objective entails designing, implementing, and testing a computer-based framework which may be employed to compare the geometric and/or architectural structures of individual plans or classes of such plans. The third objective is to integrate the two aforementioned frameworks. Computer vision techniques are used to investigate, analyze, and compare plans of buildings from a morphological standpoint. Such techniques can contribute toward detecting differences or similarities between individual plans. Their ability to search for, combine, and compare morphological information is both parsimonious and effective. Predicated on the assumption that designers derive knowledge from past solutions to form-making problems, this study focuses on the methods by which the morphological information which is contained in building plans can be extracted automatically and entered in a knowledge base. Conceptually, this is part of a larger project which entails investigating how knowledge can be incorporated in a CAD system in a manner which aids and supports the form-making process. Conceivably, the approach of this work is, wholly or partially, applicable to the problem of extracting useful information from graphic representations used in a variety of disciplines (e.g., engineering).

summary The bar in the Architectural Association, named after the bust that sat in one corner, had white formica topped tables. Each day around lunchtime these were cleaned with Vim by the bar staff, ready for the new day’s thought’s, ideas, and occasional inspirations. Students used the bar as an ideal place to discuss their work, the table tops providing an endless supply of virtual napkins waiting not to be used but to be drawn on. This atmosphere of providing a relaxed environment to discuss and debate architectural ideas proved immensly popular, with tea spills adding to the table top sketches. It is often forgotten in the ordered cleanliness of the CAD studio, where the protection of the computers overrides the comfort of their users, that ideas and their development do not always come when we most expect. Providing an atmosphere in which the designer feels comfortable enough to play is as vital now as at the time when the Architectural Association was seen as an ideal place to foster debate. As the architect feels more comfortable, so will the ideas flow more freely. This paper demonstrates how a CAD environment can become the virtual equivalent of a coffee bar as it relates to the design studio, where ideas are thrown around with abandon, and where the discussion of those ideas is more important than the material with which the ideas are depicted. In contrast, the use of computers in design is following along the same path as beautifully descriptive artwork or highly skillful technical drawings, that say much about the presentation abilities of their authors, yet often little about the actual designs. Designers often are so seduced by the medium that they do not properly see the message. A computer’s ability to present three dimesnional form instantly, and the ease with which those forms may be altered, stretched, shrunk, reversed and so on make the computer an ideal sketching tool. This paper shows the results of the combined RIBA Part II and MSc Computing and Design course. This two year, 96 week course is entirely computer based, and uses generative modelling to explore the fundamental nature of the design of form. This paper seeks to show how this approach may be successfully used with some students, and how the approach complements existing teaching methods and techniques. To accompany these notes a computer based presentation will illustrate a variety of past and present student work. This will show how rule based form, and the use of computers as a sketching tool, has influenced the students' working methods and their approach to the creation of form. Finally, we will show that the use of such a formal approach leads inevitably to a greater understanding of, and therefore a greater ability to articulate and illustrate, a student’s own design ideas and proposals. The use of the computer at every stage of the design process forces the student to be entirely explicit about every action as it occurs. Similarly the rule based approach requires them to be explicit about actions they propose to take in the future. This double combination has produced students who are highly articulate about their designs at every stage, and this paper aims to demonstrate that the more articulate the student, the greater is the possibility for success.

title Archaeological Site Reconstruction With AutoDesk's 3D Studio
source CSA Newsletter Vol 7:3 Nov 1994
summary 3D Studio is an IBM-compatible computer modeling program that enables users to create three-dimensional renderings of a variety of objects. In its ability to import a wide variety of maps and other images, 3D Studio allows for the realistic rendering of models created within AutoCAD or other 3D CAD packages. Over the past year, the Homol'ovi research program has been utilizing this software to create near photo-realistic renderings of conjectural site models. My own interests in three-dimensional computer modeling developed out of work at the site of Homol'ovi IV, a 150-room pueblo site located near Winslow, Arizona. The site was situated upon a steep 30-meter bluff with a bedrock cap. Approximately 24 rooms were located on top of the bedrock cap, with another 125 rooms situated on the slope of the butte. During the 1989 field season five structures were excavated, while a separate crew worked clearing and mapping the tops of walls. Mapping was accomplished with a Topcon EDM/theodolite station, and a standard map was created from this process. (See Fig. 3.) While the map was sufficient to show the general layout of the site, I remained unsatisfied; a 2D plan view simply did not convey the vertical dimension of the pueblo. At this point the Homol'ovi Research Program purchased a copy of AutoCAD in order to begin exploring three-dimensional mapping and modeling.

title Piecewise smooth surface reconstruction
source A. S. Glassner, (ed), Computer Graphics (Siggraph'94 proc.), Annual Conference Series, pp 295-302, July 1994
summary We present a general method for automatic reconstruction of accurate, concise, piecewise smooth surface models from scattered range data. The method can be used in a variety of applications such as reverse engineering - the automatic generation of CAD models from physical objects. Novel aspects of the method are its ability to model surfaces of arbitrary topological type and to recover sharp features such as creases and corners. The method has proven to be effective, as demonstrated by a number of examples using both simulated and real data. A key ingredient in the method, and a principal contribution of this paper, is the introduction of a new class of piecewise smooth surface representations based on subdivision. These surfaces have a number of properties that make them ideal for use in surface reconstruction: they are simple to implement, they can model sharp features concisely, and they can be fit to scattered range data using an unconstrained optimization procedure.

summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.
