summary	There is an essential contradiction between the making of buildings or built environments in a threedimensional modeler and the graphic control of this process. Three-dimensional modeling is a constructive activity, in which solids are assembled as they would be in an actual structure; it benefits the designer. Presentation and documentation, on the other hand, are prescriptive activities that direct some of the construction and all the visualization and criticism of the proposal; they benefit the user and builder. A building while being designed can be visualized and criticized from its solid model, and the model can take a variety of forms depending on its part): computer-based, drawn in orthographic or perspective projection, constructed of cardboard or wood, or described narratively by means of text, programmatic data, performance model or animation. However, practicing architecture is the process of recording and communicating the decision making process and the contractual obligations that result. In actual practice, in contrast to the designer directed ideal, more participants are brought in sooner at the beginning of a project and with more publicity, which in turn means keeping more, not fewer, records. As the profession evolves, records of the string of design decisions will become more automated, more carefully structured and more retrievable. More buildings will be "tracked" and exposed to review in this way because public environmental sensitivity will improve. The communication between a single designer and his own thoughts will become less and less important.

title	Efficiency of Model Endoscopic Simulation - An Experimental Research at the University of Stuttgart
source	Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 31-34
summary	At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.

summary	Architects and urban designers are increasingly using computers in their attempt to improve decision making in urban design. Most existing systems emphasize hard data such as statistics, land use data, etc. In recent years with the use of more powerful computers we have seen a greater emphasis on managing visual data. Computer systems are being used to generate urban models and simulations of the various kinds of impact new developments have on the existing cityscape. This project emphasizes the use of visual data. The purpose of the research has been to develop a computer system for urban designers to use in analyzing urban architectural qualities. Therefore this project focuses on applying traditional methods and theories of urban designers rather than developing new computer techniques. The traditional methods and theories of urban designers fall within the category which the French theorist Francoise Choay calls Pre-urbanism and Urbanism - the Cultural Model. Theorists within this category include Camillo Sitte, Gordon Cullen, Kevin Lynch, Leon Krier, Aldo Rossi, Michael Trieb, Roger Tranzick and Thiis-Evensen. This computer system has been developed as a prototype in order to gain experience and knowledge for future development of a large system. Later development will be based upon a vectorized threedimensional model of a whole city using texture mapping and tracing techniques to annotate important architectural features. The computer system consists of the basic analysis module supplied with a simulation unit and a theory unit. With this analytical tool, analysis is conducted on three different urban scales. The prototype has been developed on the Macintosh computer with SuperCard as the authoring tool. The computer system was developed as a prototype for Danish Urban Designers and is currently being tested in conjunction with the city of Viborg, Denmark. ( population 55,000). Located in Jutland, Viborg was the capital of Denmark around the year 1000. It now functions as a center for regional government. Viborg was selected as the test site because of its historical core.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

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.

title	The Studio CTH-A and the Searching Picture
source	Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 129-140
summary	What happens during an architect’s search for the best solution? How does he (or she) begin, which tools are chosen, what happens when he comes to a standstill? The activities – sketching, discussions with other people, making models, taking walks to think, visits to the library, etc? What is an ordinary procedure and what is more specific? Do the tools have an impact on the final solution chosen? What happens during periods of no activity? Are they important? In which fields of activities are signs of the searching process to be found? In other words — what is the process of creative thinking for architects? Mikael Hedin and myself at Design Methods, Chalmers University of Technology, have started research into architects’ problem-solving. We have finished a pilot study on a very experienced architect working traditionally, without Cad (”The Bo Cederlöf Case”). We have started preliminary discussions with our second ”Case”, an architect in another situation, who has been working for many years with Cad equipment (Gert Wingårdh). For our next case, we will study a third situation – two or more architects who share the responsibility for the solution and where the searching is a consequence of a dialogue between equal partners. At present, we are preparing a report on theories in and methods for Searching and Creativity. I will give you some results of our work up till now, in the form of ten hypotheses on the searching process. Finally, I would like to present those fields of activity where we have so far found signs of searching. Our approach, in comparison with earlier investigations into searching (the most respected being Arnheim’s study on Picasso’s completion of the Guernica) is to collect and observe signs of searching during the process, not afterwards. We are, to use a metaphor, following in the footsteps of the hunter, recording the path he chooses, what marks he makes, what tools, implements and equipment he uses. For practising architects: a better understanding of what is going on and encouragement to try new ways of searching, for architectural students: better preparation and training for problem solving. It all began while we compared the different objects in our collection of sketches at the Chalmers STUDIO for Visualisation and Communication. (For some years, we have been gathering sketches by Alvar Aalto, Jorn Utzon, Ralph Erskine, Erik and Tore Ahlsén, Lewerenz, Nyrén, Lindroos, Wingårdh and others in a permanent exhibition). We observed similarities in these sketches which allowed us to frame ten hypotheses about the searching process.

title	Hybrid Design Environments - A Research Program on Creative Collaboration and Communication
doi	https://doi.org/10.52842/conf.ecaade.1993.x.a8h
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	This paper gives an overview of a research program initiated in the Architectural Design Department of the Escola Tècnica Superior d'Arquitectura de Barcelona on issues of communication and collaboration in computer aided design. The work is centered around emerging design situations which can be attributed directly to the incorporation of new technologies in education and practice. One of these is the "design triangle" composed of a traditional designer, a CAD workstation and a computer literate collaborator acting as the design medium. Another is the "virtual workshop" consisting of design collaboration involving large-scale distributed communications networks. The research program stresses three common characteristics of these situations which it aims to study in parallel in the setting of an design workshop. The first of these is the characteristic of distance, both physical and conceptual, which separates, on the one hand, the traditional designer from the CAD document and, on the other, the participants of a distributed workshop from each other and each others' thinking. The second, is the typically hybrid nature of such situations where computer technology interacts with more traditional techniques and alternative media are combined both at the level of production and in channels and modes of communication. And finally, the third and most significant for the methodology of the research program, is the fact that both the design triangle and the virtual workshop make explicit aspects of design activity, interaction and intentions which remain hidden or are only implicit in traditional designing.

title	A toolset for navigation in virtual environments
source	Proceedings of the ACM User Interface Software and Technology, pp.157-165
summary	Maintaining knowledge of current position and orientation is frequently a problem for people in virtual environments. In this paper we present a toolset of techniques based on principles of navigation derived from real world analogs. We include a discussion of human and avian navigation behaviors and show how knowledge about them were used to design our tools. We also summarize an informal study we performed to determine how our tools influenced the subjects' navigation behavior. We conclude that principles extracted from real world navigation aids such as maps can be seen to apply in virtual environments.

title	A Computer-Assisted Diagramming System
source	Swiss Federal Institute of Technology, ETH Zurich
summary	This research investigates characteristics and generation of graphic diagrams used in support of analysis, presentation and synthesis of information in various domains. The research is aimed at the development of a software system which can be used to specify, generate and manipulate diagrams similar to the way they are represented and operated upon in traditional media.Diagrams are graphic representations of symbolic propositions that allow tentative reasoning and inferencing, and enable a person to focus on selected aspects of a situation that are deemed of interest. The economy and directness of expression found in diagrams seem to be the prime reasons why they are so ubiquitous in many domains. Despite these advantages, studies into supporting diagrammatic representations using computers are rather sparse. This research is an attempt at developing a comprehensive framework of thought in this direction.In the context of design disciplines like architecture, this research forms a part of the continuum of studies in computer aided design techniques and tools. While a large number of tools and techniques in CAD have emerged so far, usage of such tools, due to their underlying representations, expects and demands commitment of too many details too early in the design process. This research is aimed at characterizing and developing a computer based diagramming system to support tentative reasoning using diagrams, and thus hopes to extend the scope of CAD environments in design.The thesis first articulates motivations for this topic in detail. Next, a discussion on the role played by diagrams as conceptual tools in various domains is presented. It is followed by a detailed look at characteristics and components of diagrams viewed as a graphic communication system. Next, a comprehensive set of requirements for an ideal software environment for diagramming tasks is developed. A prototype system called CDT was implemented and is used to demonstrate ideas developed in this research. The study concludes with some observations on contributions of this research effort and possible future extensions.

title	Grow: Generative Responsive Object for Web-based design - Methodology for generative design and interactive prototyping
doi	https://doi.org/10.52842/conf.ecaade.2014.2.587
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 587-594
summary	This paper is part of the research on Generative Design and is inspired by the ideas spread by the following paradigms: the Internet of Things (Auto-ID Center, 1999) and the Pervasive/Ubiquitous Computing (Weiser, 1993). Particularly, the research describes a number of case studies and, in detail, the experimental prototype of an interactive-design object: “Grow-1”. The general assumptions of the study are as follows: a) Developing the experimental prototype of a smart-design object (Figure 1) in terms of interaction with man, with regard to the specific conditions of the indoor environment as well as in relation to the internet/web platforms. b) Setting up a project research based on the principles of Generative Design.c) Formulating and adopting a methodology where computational design techniques and interactive prototyping ones converge, in line with the principles spread by the new paradigms like the Internet of Things.

summary	Simulating the development and the image of architecture and urban design means to show how the environment of the future and the living conditions could develop. At the same time it is part of our task to explain our work to local people and to the public and to passion skills in methods, instruments and knowledge in planning to the next generation of architects, planners and last but not least to discuss and to renew them once more for ourselves. Our aim was also to reflect what we have done since starting the look through the key-hole of endoscopy. Meanwhile this look has been completed since the beginnings in 1993 much more by computer and monitor. It is not the question to take the endoscope or the computer as a methodical and instrumental approach. Nowadays we normally decide to take the endoscope and the computer. In preparing the conference and the workshop we thought that this should now also be the moment not only to inform each other and the participants on methods, tools and best practices in simulating and designing the environment but also to focus on the social and human consequences of perception, movement and use the present urban spaces and the urban space in future. So we proposed the theme “MOTION, E-MOTION and URBAN SPACE” and we invited a scientific expert in experimental psychology to give us some serious reflections and one or another hint on our research themes and methods. The contributions and discussions in the conference showed that the proposal has not only been accepted but has also been completed and enriched especially concerning the theme urban space, it’s processes of usage and it‘s atmosphere. Also in the themes of endoscopy and the research on modelling urban spaces and architecture, meanwhile nearly “traditional” ones, remarkable results were presented and discussed. A very important point of contributions and the following discussions was how to present our subjects to the interested public and to improve our own internal exchange. An object could be to enforce the research tasks in researching together even more.

summary	In the proceedings of the first EAEA conference, 1993, I mentioned our first study focused on refining endoscopic video images of a detailed architectural model and drawings. The study was based on work with 900 subjects, of which 200 were professional architects. It has led to a number of technical improvements. In the second study we compared computer-aided design techniques with two techniques from the first study, endoscopic video recordings and coloured and black and white elevations and perspective drawings. Four different groups of 50 subjects took part in this research. We found that computer images are invariably judged to be of moderate value, while drawings yielded consistently high scores. Endoscopic video recordings of the scale model received high scores as far as emotional response is concerned, and moderate scores when the participants were questioned on the actual content of the recordings.

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.

source	Town Planning Review, 64(2), pp. 193-212
summary	A study was undertaken of the application of computer visualisation to the control of design by local planning authorities in England. Several examples of major urban development and routine development control work were visualised for local councils, the images fed back into the decision-making process, and the results monitored. While the investigation of the decision-making process is still continuing, the results obtained to date demonstrate an important role for visualisation. The work undertaken is described and comment is made on both the pattern of possible use by a planning authority and the general issue of the objectivity of the images.

title	Spatial Perception in Virtual Environments: Evaluating an Architectural Application
source	IEEE Virtual Reality Annual International Symposium, 1993, Seattle
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.

source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The interdisciplinary research project aims at the development of a hard- and software environment to support the representation, analysis, manipulation and design of urban development areas for architects and city planners. It was started in 1990 and involves three groups at the ETH Zurich: Architecture/Urban design - Processing of Geographic Data/Photogrammetry -Computer Sciences/CAAD. The first part of this paper will give an introduction to the goals and implications of the project by comparing it with a similar project one of the authors took part in as a student. Then the paper gives a brief description of the work of the three groups involved, an overview of the methods they employed and the results that were achieved. The main focus will be on the work of the CAAD group . Finally some conclusions are drawn and problems are discussed. The future work includes the testing of the tool by students during the winter term 1993/94.

title	Making Reinforced Concrete Cross-sections Design Easy and Understandable
doi	https://doi.org/10.52842/conf.ecaade.1993.x.d3r
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Modern computing facilities provide an alternative graphical approach to the design of cross-sections. A description of this process might be "strength evaluation", since, for any chosen cross-section, concrete strength, and reinforcement size, location, and yield strength, the flexural resistance (capacity) is defined by the bending moment-axial force interaction diagram. The factored forces are then plotted into the diagram and, by comparing the capacity and demand on the computer screen, the designer can decide about the suitability of the chosen cross-section. If necessary, the cross-sectional properties can be changed easily. There are several advantages of this design approach. The design procedure is fast, clear and economical. For example, all loading combinations for all the columns of the frame in Fig. 1 can be checked simultaneously. The procedure is the same for various shapes of cross-sections and it enables simple reinforcement optimization as well as the typization of cross-sections. For example, only two types of cross-sections can satisfy the design requirements for all the columns in the mentioned frame.

summary	This paper describes the latest in a series of real-world, low-cost interfaces for virtual reality. nAVRgate (the AVR being Architectural Virtual Reality) has looked at real-world analogies for interfacing with 'real' virtual environments in an attempt to improve the sense of presence, the phenomenon of sense of presence in virtual environments (VEs) often being seen as the real essence of Virtual Reality (Laurel, 1993)

title	Parallel Modeling: Addressing the Issues of Creative Designing in CAD Environments II. Special Applications
source	Proceedings of the Fifth International Conference on Human-Computer Interaction 1993 v.1 pp. 249-254
summary	We postulate that Industrial Designers, in general, solve a given problem by generating a series of proposed solutions to that problem, each proposal, in theory, helps the designer to converge on the ideal solution. Any number of solutions may be under continuous development at any one time and any previous solutions should always be available for appraisal and viewing. The single modeling environment provided in traditional Computer Aided Design (CAD) systems does not support this practice. Thus, CAD systems are primarily used to address the final phases of the design process, such as analysis, visualisation and detailing. This is surely not utilising the full potential of such a powerful design tool. In an attempt to develop a less restrictive working practice for CAD users, we consider a parallel modeling approach. This solution allows the simultaneous development, design and review of a number of computer based solutions.

title	Open Simulation Environments: A “Preference-Based” Approach
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 195-214
summary	This paper introduces in conceptual, algorithmic and implementation terms, the notion of an "open" simulation environment as a "multidirectional" approach to computer-aided performance modelling. A "preference- based" formalization of design intentions/criteria is proposed to cope with the "ambiguity" problem through dynamic control of degrees of freedom of relevant design-related parameters during the interactive design process. A prototypical realization of an open simulation environment called "GESTALT' for simultaneous treatment (parametric manipulation) of various design and performance variables is demonstrated. Some preliminary results of computer-assisted generation of performance-responsive designs are presented.
