title	Describing Spaces of Rectangular Dissections via Grammatical Programming
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 143-158
summary	For the description of design spaces, grammatical programs offer several advantages over conventional grammars: (1) they integrate rewrite rules with more general non-deterministic functions, (2) they permit a range of programming styles from purely declarative to purely procedural, (3) they can describe spaces Of constrained, parametric designs, and (4) they permit design space descriptions to be developed modularly. We demonstrate these features of grammatical programming by way of a simple example that generates spaces of rectangular dissections.

title	The Relation Between the Internet Infrastructure and the Internet Industry
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The scene is set by a survey of new location factors for mobile investment in Europe, published by the European Commission in 1993. This leads to two questions the first of which concerns the exact definition of the Internet industry in order to avoid confusion. The definitional issue appears to be far from simple. The second question is about the Internet infrastructure. This infrastructure, although new and almost invisible, can nevertheless be mapped and measured with less ambiguity than the Internet industry. How to connect the two? How to establish the importance of the Internet infrastructure for the location of the Internet industry? Technological determinism and urban dissolution are debunked as myths. A conceptual innovation is called for: to conceive of the connection between infrastructure and industry as a match between networks. By way of conclusion, this match is discussed from the viewpoint of non-hub cities or regions.

title	Renderings. Some Technical and Non Technical Questions Raised by the Use of Computers in the Visual Analysis of Architecture
doi	https://doi.org/10.52842/conf.ecaade.1993.x.a5t

summary	It should be expected, in a Congress, that participants bring with them, not only ideas, but also results or, at least, stimulating images. In the Laboratory of Architectural Graphic Techniques at the ETS of Barcelona, we have spent some time generating images directly related with architecture, based on the work of both students and professors. These images have been produced with academic purposes, but also in relation with some works carried out with City Institutions interested in the study of the evaluation of environment visual impact and the role that computers may play in this area. In our previous Congress, in Barcelona, we showed some of these images, obtained by direct digital processing of bitmaps. In another Congress, later, we showed some other images, obtained by rendering, with simple local models (Phong models) and some tricks that helped to make them more realistic. Although I do agree with the old chinese saying that a good image is worth a thousand words, in this case, I have thought more convenient to present a paper that may be read quietly by those interested in these subjects, that might be useful just as it gathers references known by many but grouped in a particular order, and that pretends, respectfully, to criticize the actual situation. This can explain why we consider that the results we have obtained should be improved by new and better techniques and why we think that this dissatisfaction should be shared by others who do not seem to feel the same as we do. The aim of this contribution is, therefore, to reflect on the actual situation and the ways there seem to be open for us to follow.

source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	This paper shows work exemplifying the further extent of computer capabilities in the field of design. The work stems from a belief that for computers to be used effectively within the architectural profession their utility must stretch far beyond the process of description of geometric data, but be incorporated in the fundamental roots of design: that of conceptual design. Computers can be used to access the knowledge we have and then formulate this knowledge into a working language of design. Computers can be used to generate space and form in accordance with any relationship the designer may choose to set. This allows them to be used from the very conception of design. It is only by working from the very beginning, the very basis of the design of a building that we can fully develop the integration of computers in the construction industry. The work undertaken sets out primarily to explore one of the ways computers could be used in the field of architectural design. In recognition that an important byproduct of any design search is the enhanced understanding of the problem itself, the work was directed towards a particular project. This allowed each stage of thought to be to be considered as it arose and subsequently incorporated into the design model. The work does not attempt to automise the design process but simply tries to explore some of the opportunities offered by computers and see if they can be easily incorporated into the design process offering design solutions that may not otherwise have been considered. The exploration resulted in a simple design process model that incorporates the more accessible and useful aspects of computer technology.

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.

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.

title	On the Correlation of Design and Computational Techniques in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.1993.x.g6i
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Many studies employ analyses of human intelligence as justification or guideline for the development of machine intelligence. The main benefit brought on by such studies has been the improvement of our understanding of both human and machine intelligence. In teaching architecture with computers the same approach can make explicit design techniques architects use by means of equivalent or similar computational techniques. Explicitation of design techniques leads to a better understanding of architects' activities, as well as to which computer tools can offer automated support to these activities. In the curriculum of the Faculty of Architecture, Delft University of Technology, relations and correspondences between computational and design techniques form a major underlying theme in computer-aided design courses. The purposes of this theme are (i) comprehension of the computational structure of a computer design tool, and (ii) explanation of how such computational structures relate to architectural design. (correspondences between the computational principles of computer programs and design techniques are instrumental in defining the scope of each computer tool in architectural design while improving the students' understanding of architectural design as a cognitive process and thus promoting automation as a natural extension of established conventional practices. The paper outlines the correlation of computational and design techniques in the case of electronic spreadsheets. Spreadsheets are introduced through a thorough presentation of the various kinds and aspects of constraint propagation, their underlying computational principle. Numerical constraint propagation is explained by means of spreadsheet applications for simple numerical calculations. Symbolic constraint propagation is presented in the framework of machine perception. Both forms are then linked to architectural design through parametric design and the recognition of spaces in floor plans. Exercises linked to spreadsheets and constraint propagation include the parametric calculation of stairs and making parametric variations of a building on the basis of floor area calculations.

title	Mapping a Single Data Stream to Multiple Auditory Variables: A Subjective Approach to Creating a Compelling Design
source	Proceedings of the Third International Conferenceon Auditory Display, Santa FO Institute
summary	Representing a single data variable changing in time via sonification, or using that data to control a sound in some way appears to be a simple problem but actually involves a significant degree of subjectivity. This paper is a response to my own focus on specific sonification tasks (Kramer 1990, 1993) (Fitch & Kramer, 1994), on broad theoretical concerns in auditory display (Kramer 1994a, 1994b, 1995), and on the representation of high-dimensional data sets (Kramer 1991a & Kramer & Ellison, 1991b). The design focus of this paper is partly a response to the others who, like myself, have primarily employed single fundamental acoustic variables such as pitch or loudness to represent single data streams. These simple representations have framed three challenges: Behavioral and Cognitive Science-Can sonifications created with complex sounds changing simultaneously in several dimensions facilitate the formation of a stronger internal auditory image, or audiation, than would be produced by simpler sonifications? Human Factors and Applications-Would such a stronger internal image of the data prove to be more useful from the standpoint of conveying information? Technology and Design-How might these richer displays be constructed? This final question serves as a starting point for this paper. After years of cautious sonification research I wanted to explore the creation of more interesting and compelling representations.

title	Measuring the effect of attention on simple visual search
source	Journal of Experimental Psychology: Human Perception and Performance 19(1) 108-130.
summary	It is unclear to what extent attention affects perception rather than memory and decision. Is all of perception limited by attention, or is perception completely preattentive, and attention only affects memory and decision, or some compromise? The answer is in your definitions of these phenomena. Visual search task: display set size The display set size increases response time and/or response accuracy. This is a putative example of divided attention in the literature. The goal of this paper is to be more rigorous in studying this setsize phenomena, and try and decouple attention on perception Display set size: The total number of stimuli in an experiment. Relevant set size: Total number of 'cued' stimuli in an experiment.

title	Incommensurability of Criteria and Focus in Design Generation
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 111-125
summary	An approach to developing design systems is presented, informed by the recognition that design criteria are incommensurable. The degree to which an artifact satisfies one criterion cannot be compared to the degree to which it satisfies another. Given this principle, it is not valid to combine different "scores " given to independent features in an evolving design into a global evaluation function. The design framework proposed here represents an alternative to the traditional approaches for combining independent criteria and organizational principles. It is based on the opportunistic nature of designing, the multiplicity of semantics active in a design session, and the dynamics of focus and distraction. By way of illustrating both this characterization of designing and the abstract computational framework on which it is based, a simple system for arranging blocks according to a set of formal massing principles is presented. The massing generator has some important properties that other systems lack, such as dynamism, robustness and the ability to deal with partial designs. Through a comparison with some artificial intelligence methods such as production systems and search, the proposed framework is used as a guideline for developing design systems. This paper focuses on designing as an activity, rather than engaging in an analysis of finished designs with the hope of capturing their syntactic properties. Thus the stress is placed on the generator's behavior, by giving examples of how it converges on a series of design alternatives in a dynamic fashion, avoiding oscillations and blocks.

source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	The Creative Synthesis task devised by Finke and Slayton(1988) has been widely used as an experimental measure of mentalsynthesis, but previous studies have often failed to demonstrate anysignificant benefits of external support on participants’ performance.This paper discusses a study that examined novice and expert drawers’performance of synthesis using a modified stimuli set that was designedto increase the load on visuo-spatial working memory. The resultsshowed a significant increase in Transformational Complexity(Anderson & Hesltrup, 1993) of patterns produced by the expert groupwhile using sketching. It is argued that experts are more effective atusing sketching interactively to increase complexity, while novices relymore on using it as a simple memory aid.

summary	It can be easily observed, at least in Spain, that there are many members of the academe within the field of architecture who still confuse the use of the computer with the teaching of architecture. It as if the simple fact of having an access to a computer were a giant step in the development and dominion of architecture.

title	Computational Analysis of the Environmental Impact of Building Designs
source	Carnegie Mellon University, Pittsburgh
summary	Concem for the environmental implications of human activities is becoming increasingly important to society. The concept of current development that does not compromise future generations! abilities to meet their needs is a goal for many communities and individuals (WCED 1987). These concerns require the evaluation and assessment of the potential environmental impact of human activities so that informed choices can be made. Building construction and operation activities are of significant importance in view of a) national and intemational economies, 6) resource consumption, c) human occupancy, and d) environmental impact. For example, in the United States the built environment represents an extensive investment, both as an annual expenditure and as an aggregate investment. In the mid-l980’s, up to 30% of new and remodeled buildings had indoor air quality related complaints. Buildings also consume approximately 35% of the primary energy in the U.S. every year, resulting in the release of 482 million metric tons of carbon in 1993.I Methods developed to assess the environmental impact of buildings and development patterns can and have taken multiple strategies. The most straightforward and simple methods use single factors, such as energy use or the mass of pollutant emissions as indicators of environmental performance. Other methods use categorization and weighting strategies. These gauge the effects of the emissions typically based on research studies and use a weighting or effect formulation to normalize, compare, and group emissions so that a scalar value can be assigned to a single or a set of emissions. These methods do not consider the characteristics of the context where the emissions occur.

title	The Vector-drawing as a Means to Unravel Architectural Communication in the Past
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q9a
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

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	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	This paper presents a method for determining elemental square foot costs and cost significance for residential construction. Using AutoCAD's icon menu and dialogue box' facilities, a non-expert may graphically select (i) residential configuration; (ii) construction quality level; (iii) geographical location; (iv) square foot area; and finally, (v) add-ons, e.g. porches and decks, basement, heating and cooling equipment, garages and carports etc. in order to determine on-site builder's costs. Subsequent AutoLisp routines facilitate data transfer to a Lotus 1-2-3 spreadsheet where an elemental cost breakdown for the project may be determined. Finally, using Lotus 1-2-3 macros, computed data is transferred back to AutoCAD, where all cost significant items are graphically highlighted.

doi	https://doi.org/10.52842/conf.ecaade.1993.x.i6u
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The idea of artificial brains and artificial intelligence (AI) has been subject to criticism. The objection of J. Searle, for instance, which has been published in 1984 and which was partially directly addressed to one of the centres of AI, the Carnegie Mellon University in Pittsburgh, is mainly based on two points: (1) interactions between physiological and mental functions, and (2) the intentionality and context-relatedness of meaning. - With an emphasis on architectural design, this paper is about the second point, because the problem of meaning is a neuralgic point in the discussion of "artificial intelligence in design" (AID). Technical parameters are incompatible with mechanisms of meaning in any field of artistic, cultural or non-technical expression. This point, that is the relation between acts of meaning and acts of technical problem-solving and, connectedly, the relation between technological and architectural design, has been widely ignored in the discussion on AID. The development seems to be dominated by the tacit assumption that architecture can be articulated and generated purely in technical and formal terms of information processing beyond the field of architecture itself. Design and shape grammars have become a well established field in the discussion of AID, also with respect to architecture. But questions of architectural history and theory are touched on only incidentally and not sufficiently in this discussion. The problem is not, in other words, simply to include more or less unrelated cases of architecture, or architectural concepts -even if these are famous ones, such as Laugier's original hut for instance but to establish structural relations between arguments of architectural theory and arguments of AID.

title	Social and Psychological Aspects of Computer-Aided Design Systems Social Aspects of Information Technology
source	Behaviour and Information Technology 1993 v.12 n.5 p.267-275
summary	A study was performed among design employees in three large companies to investigate the psychosocial effects of computer-aided design (CAD) work. The study included all technical employees of the departments selected, of whom about two-thirds worked with CAD systems. The results demonstrate that 90% of the CAD users have a positive attitude to CAD-work. No significant differences were found between CAD users and non-CAD users in terms of work load, autonomy, social support, job satisfaction, personal development, or degree of co-operation. Within the group of CAD users, those spending a larger number of weekly working hours with the CAD system reported lower work complexity, lower autonomy of work methods, and less job satisfaction. CAD users with a relatively higher number of years of CAD experience reported a greater work load, fewer CAD difficulties, and lower autonomy of work methods. Among draftspersons and designers, there were no significant differences in work activities between CAD users and non-CAD users.

source	[Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4] Vienna (Austria), 30 August - 1 September 1995, 144p.
summary	The first EAEA-Conference took place at Tampere University of Technology (Finland, 1993) serving as an meeting point for specialists of endoscopy in architecture and displayed an approach to the potentials of endoscopy. The Vienna Conference in 1995 continued this direction and tried furthermore to serve as a platform for non-advanced users. EAEA '95 Vienna aimed at a critical investigation of today's endoscopic culture. The Aspern-Workshop represented the highlight of this conference. Prior to the conference nine universities had submitted endoscopic and computer-assisted space simulations for this urban expansion area north of the Vienna Danube. The outcome was not to be regarded as a “noble competition” between the various institutions participating, but rather to sound out the actual potential of various simulation techniques and their combinations for future use. The conference proceedings contain the papers presented at the meeting by 23 experts from 15 universities. The papers cover such areas as the technical features of endoscopy and environmental simulation, theories supporting the use of endoscopy, practical applications, and discussions on the future of endoscopy and environmental simulation in comparison with other means of architectural representation.

title	PLASM Functional Approach to Design: Representation of Geometry
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 127-141
summary	PLASM (the Programming Language for Solid Modeling) is a solid-modeling-oriented design language strongly inspired by the functional language FL. In a PLASM environment, every geometrical object is generated by evaluating a suitable language expression which produces a polyhedral solid model. The language adopts a dimension-independent approach to geometry representation and algorithms. The generated objects are always geometrically consistent since the validity of geometry is guaranteed at a syntactical level. In fact (a) each well-formed expression is obtained by proper composition of well-formed subexpressions; (b) the evaluation of a well-formed (and polyhedrally typed) expression produces a valid solid model. In this paper, the representation scheme used in the language is given and some language scripts are shown and discussed.
