title Visualization of Three-Dimensional Structure During Computer-Aided Design
source International Journal of Human-Computer Interaction 1995 v.7 n.1 pp. 37-56
summary The visual image presented to an engineer using a computer-aided design (CAD) system influences design activities such as decision making, problem solving, cognizance of complex relationships, and error correction. Because of the three-dimensional (3-D) nature of the object being created, an important attribute of the CAD visual interface concerns the various methods of presenting depth on the display's two-dimensional (2-D) surface. The objective of this research is to examine the effects of stereopsis on subjects' ability to (a) accurately transfer to, and retrieve from, long-term memory spatial information about 3-D objects; and (b) visualize spatial characteristics in a quick and direct manner. Subjects were instructed to memorize the shape of a 3-D object presented on a stereoscopic CRT during a study period. Following the study period, a series of static trial stimuli were shown. Each trial stimulus was rotated (relative to the original) about the vertical axis in one of six 36° increments between 0° and 180°. In each trial, the subject's task was to determine, as quickly and as accurately as possible, whether the trial object was the same shape as the memorized object or its mirrored image. One of the two cases was always true. To assess the relative merits associated with disparity and interposition, the two depth cues were manipulated in a within-subject manner during the study period and during the trials that followed. Subject response time and error rate were evaluated. Improved performance due to hidden surface is the most convincing experimental finding. Interposition is a powerful cue to object structure and should not be limited to late stages of design. The study also found a significant, albeit limited, effect of stereopsis. Under specific study object conditions, adding disparity to monocular trial objects significantly decreased response time. Response latency was also decreased by adding disparity information to stimuli in the study session.

summary A building comprises of more than the skin and the structural works. It is the soul that comes in the form of SPACE that is intriguing and provokes the mind. To be able to experience a building relies heavily on the spatial concept and internal lay out. How one is captured right from entering the entrance and through the layering of space, of horizontal and vertical planes and finally the euphoria, or depressed feeling that concludes the tour depending on the feeling intended (Miller, 1995). The common norm at present celebrates the outer skin and grandeur of facades. Not many include the hidden grids and fragmentation that can lead to a surprisingly good form AND space. Thus a number of them fail, in the sense of a sensuous building. ‘The circulation path can be conceived as the perceptual thread that links the spaces of a building or any series of interior or exterior spaces, together. Since we move in TIME, through SEQUENCE of SPACES, we experience a space in relation to where we’ve been, and where we anticipate going’ (Ching, 1979). This research intends to study and analyze the unconventional electronic gallery or ‘e-gallery’ as a versatile hybrid container. The focus of the research will be on documenting spaces in the e-gallery, bringing to light the unlimited possibilities that can take place in such a space.

summary Typological design implies extensive knowledge of building types in order to design a building belonging to a building type. It facilitates the design process, which can be considered us a sequence of decisions. The paper gives an outline of a new approach in a course teaching typological knowledge through the medium of Knowledge-Based Systems programming. It demonstrates how Knowledge-Based Systems offer an appropriate structure for analysing the knowledge required to implement typological design. The class consists of third-year undergraduate students with no extensive previous programming experience. The implementation language is AutoLISP which operates in the AutoCAD environment. The building type used in the course is the office building. in order to become acquainted with both building type and programming in AutoLISP, information and instructions have been gathered and prestructured, including a worked out analysis and AutoLISP code. Office plans are generated through use of the Knowledge-Based System. They are encoded in the form of frames. At the end of the course the students will have learned the basics of Knowledge-Based Systems, have been introduced to programming these systems, have analysed and reflected upon the design process, and gained insight into a specific building type.

summary This paper presents a method of using multimedia techniques in order to solve problems of visual pollution of city environment. It is our observation that human - inducted degradation of city environmental results not only from neglect and vandalism but also from well - intentioned but inappropriate preservation actions by uninformed designers and local administrations. Very often, a local municipality administration permit to erect an ugly, bad-fitting surroundings houses. It is usually connected with lack of informations about certain areas of a city, its features, characteristic and about present and earlier buildings. Therefore there was an experiment - a complex programme aiding the decision process as a part of the CAMUS system (Computer Aided Management of Urban Structure) which is created at Faculty of Architecture TUB. One of the integral parts of it is a block, which has been called "How would it be like to be nice around". One of the basic elements of that system is a town data base consisting of the independent knowledge - based systems, working together in a distributed computing environment. City administration will have access to each information from multimedia data-base. Multimedia is also having and impact on the effectiveness of decision process in urban planning and in our fight with ugliness of the city.

title Some Experimental Results in the Assessment of Architectural Media
source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 163-171
doi https://doi.org/10.52842/conf.acadia.2000.163
summary The relationship between the media and architectural design can be an important factor and can influence the design outcome. However, the nature, direction and magnitude of this relationship are unknown. Consequently, there have been many speculative claims about this relationship and almost none of them are supported with empirical research studies. In order to investigate these claims and to provide a testable framework for their potential contributions to architectural education, this study aims to explore the effects of media on architectural design. During 1995-1997, a total of 90 students enrolling in First Year Design Studio and Introduction to Computing classes at Georgia Tech participated in the study. A set of quantitative measures was developed to assess the differences between the two media and the effects on the architectural design. The results suggested that media influenced certain aspects of students’ designs. It is concluded that there is a strong relationship between the media and architectural design. The type of media not only changes some quantifiable design parameters but also affects the quality of design.

title Faculties of Architecture
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In order to be inscribed in the European Architect’s register the study program leading to the diploma ‘Architect’ has to meet the criteria of the EC Architect’s Directive (1985). The criteria are enumerated in 11 principles of Article 3 of the Directive. The Advisory Committee, established by the European Council got the task to examine such diplomas in the case some doubts are raised by other Member States. To carry out this task a matrix was designed, as an independent interpreting framework that mediates between the principles of Article 3 and the actual study program of a faculty. Such a tool was needed because of inconsistencies in the list of principles, differences between linguistic versions ofthe Directive, and quantification problems with time, devoted to the principles in the study programs. The core of the matrix, its headings, is a categorisation of the principles on a higher level of abstractionin the form of a taxonomy of domains and corresponding concepts. Filling in the matrix means that each study element of the study programs is analysed according to their content in terms of domains; thesummation of study time devoted to the various domains results in a so-called ‘profile of a faculty’. Judgement of that profile takes place by committee of peers. The domains of the taxonomy are intrinsically the same as the concepts and categories, needed for the description of an architectural design object: the faculties of architecture. This correspondence relates the taxonomy to the field of design theory and philosophy. The taxonomy is an application of Domain theory. This theory,developed by the authors since 1977, takes as a view that the architectural object only can be described fully as an integration of all types of domains. The theory supports the idea of a participatory andinterdisciplinary approach to design, which proved to be awarding both from a scientific and a social point of view. All types of domains have in common that they are measured in three dimensions: form, function and process, connecting the material aspects of the object with its social and proceduralaspects. In the taxonomy the function dimension is emphasised. It will be argued in the paper that the taxonomy is a categorisation following the pragmatistic philosophy of Charles Sanders Peirce. It will bedemonstrated as well that the taxonomy is easy to handle by giving examples of its application in various countries in the last 5 years. The taxonomy proved to be an adequate tool for judgement ofstudy programs and their subsequent improvement, as constituted by the faculties of a Faculty of Architecture. The matrix is described as the result of theoretical reflection and practical application of a matrix, already in use since 1995. The major improvement of the matrix is its direct connection with Peirce’s universal categories and the self-explanatory character of its structure. The connection with Peirce’s categories gave the matrix a more universal character, which enables application in other fieldswhere the term ‘architecture’ is used as a metaphor for artefacts.

summary This paper presents a method for representing complex models with various levels of detail. It is based on a geometric simplification algorithm and is applied to a scene described by a rooted-tree structure. In order to control the restuting image quality and the computation time, we propose two algorithms which allow to choose one representation of the scene.

title Designing Architectural Experiences: Using Computers to Construct Temporal 3D Narratives
source Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 139-149
doi https://doi.org/10.52842/conf.acadia.1995.139
summary Computers are launching us into a representational revolution that fundamentally challenges the way we have hitherto conceived and practiced architecture. This paper will explore one of its fronts: the simulation of architectural experiences. Today's off-the-shelf softwares (e.g. 3D modeling, animations, multimedia) allow us for first time in history to depict and thus approach architectural design and criticism truly experientially. What is so appealing about this is the possibility of shifting our attention from the object to the experience of the object and in so doing reconceptualizing architectural design as the design of architectural experiences. Carrying forward such a phenomenological proposition requires us to know (1) how to work with non-traditional and 'quasi-immersive' (or subject-centered) representational systems, and (2) how to construct temporal assemblages of experiential events that unfold not unlike 'architectural stories'. As our discipline lacks enough knowledge on this area, importing models from other fields appears as an appropriate starting point. In this sense, the narrative arts (especially those involved with the temporal representation of audio-visual narratives) offer us the best insights. For example, principles of cinema and storytelling give us an excellent guidance for designing architectural experiences that have a structuring theme (parti), a plot (order), unfolding episodes (rhythm), and special events (details). Approaching architecture as a temporal 3D narrative does transform the design process and, consequently, its results. For instance, (1) phenomenological issues enter the decision making process in an equal footing to functional, technological, or compositional considerations; (2) orthographic representations become secondary sources of information, mostly used for later accurate dimensioning or geometrization; (3) multi-sensory qualities beyond sight are seriously considered (particularly sound, texture, and kinesthetic); etc.

doi https://doi.org/10.52842/conf.ecaade.1995.427
summary We report on an on-going Ph.D. research aimed at the analysis of the nature of process knowledge in architectural design and the development of a conceptual model for a case-based navigation tool for its support. We describe architectural design from a process viewpoint and assume it as a form of intentional planning, leading from an initial state configuration toward a desired situation, by means of an incremental specification of goals, constraints and involved variables. We consider the very essence of design and of the specific professional skill characterising designers as the continual recursive transformation of the initial solution model, in order to map the desired state onto the enacted one and the capability to govern a number of continually changing variables in this direction. On the basis of this general concept of the design process, we describe the model of Galathea, a case-based planning tool, aimed at progressively representing the enlarging space of acquired knowledge, and at supporting the designer´s central role in the management of the design process.

summary In this paper a way of combining endoscopy with architectural notations will be presented. Endoscopy is regarded as a tool to visualize sequences from a model in order to demonstrate how the environment will look like from the pedestrian’s or driver’s view. But while using it, its limitations must be considered. The model is mostly too small to present distant landmarks, districts, nodes and edges of importance. And most important, experience of space is not only visual. It is a complex process where many aspects must be taken into consideration. These aspects can be presented with architectural notations on physical drawings of the situation. The resulting “storyboard” is most useful in analyzing the situation and making better solutions possible.

summary An inherent problem with creating a multimedia application is generating the mass of information needed in order for it to be comprehensively useful. This is especially true when the subject is building construction for which any informative resource must cover the whole range of the material within its scope from the outset rather than merely be a sampler. Construction studies involve a large and diverse range of ´generic´ or ´model solutions´ which, in an ideal learning situation, are placed in context with historical and contemporary examples to aid a sense of critical evaluation. An obstacle, then, against creating resources dealing with detailed design is the risk that if it is not completed in its entirely there is no useful outcome. This paper also describes the problems and solutions involved in treating this material as data in a generic format so that its future usefulness is not compromised by current needs. It also outlines the programmes written to streamline an otherwise unwieldy process and deal with the inevitable non-conforming output from the participants.

title A Brief Note on Virtual Space
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 83-92
summary In its efforts to represent space, and then create architecture on the basis of this representation, humanity has taken three major steps. STEP 1. Representation of space in the form of a drawing or model; representations compared to the mental vision and then redrawn or remodelled, until the vision takes the shape of a finished building. This technology of design" followed different conventions, depending on the epoch. In the Middle Ages the method of approximation by triangles was introduced. The Renaissance used Projection, Elevation and Cross-Section. In order to construct a building, a flat, abstract representation is used, supplemented by a model showing spatial relations and a verbal description, impossible to convey graphically. STEP 2. Methods as in Step 1, but, beginning in the 1970s, with the use of computers, which allows also for the gradual integration of these methods in one program. Theoretically speaking, all necessary data can be now recorded, visualized, animated, etc., on a PC class computer. The design-aid software is based on the method of creating a 3D model of the whole building, and then generating the rest (projections, cross-sections) from it. STEP 3. The above step have - brought us to near- perfection in photorealistic representation of space, which remains, however only a 2D abstraction from 3D space. The next step, which is now taking place before (and in?) our very eyes, is to use systems which bring us directly into 3D space.

summary It appears by now fairly accepted to many researchers in the field of the Computer Aided Architectural Design that the way to realize support tools for these aims is by means of the realization of Knowledge Based Assistants. This kind of computer programs, based on the knowledge engineering, finds their power and efficaciousness by their knowledge base. Nowadays this kind of tools is leaving the research world and it appears evident that the common graphic interfaces and the modalities of dialogue between the architect and the computer, are inadequate to support the exchange of information that the use of these tools requires. The use of the knowledge bases furthermore, presupposes that the conceptual model of the building realized by others, must be made entirely understandable to the architect. The CAAD Laboratory has carried out a system software prototype based on Knowledge Engineering in the field of hospital buildings. In order to overcome the limit of software systems based on usual Knowledge Engineering, by improving architect-computer interaction, at CAAD Lab it is refining building model introducing into the knowledge base two complementary each other methodologies: the conceptual clustering and multimedia technics. This research will make it possible for architects navigate consciously through the domain of the knowledge base already implemented.

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.

summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title SageBook: Searching data-graphics by content
source Proceedings of CHI , ACM Press
summary Currently, there are many hypertext-like tools and database retrieval systems that use keyword search as a means of navigation. While useful for certain tasks, keyword search is insufficient for browsing databases of data-graphics. SageBook is a system that searches among existing data-graphics, so that they can be reused with new data. In order to fulfill the needs of retrieval and reuse, it provides: 1) a direct manipulation, graphical query interface; 2) a content description language that can express important relationships for retrieving data-graphics; 3) automatic description of stored data-graphics based on their content; 4) search techniques sensitive to the structure and similarity among data-graphics; 5) manual and automatic adaptation tools for altering data-graphics so that they can be reused with new data.

title A Logic-Based Framework for Representing Architectural Design Knowledge
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 91-102
summary This paper proposes a logic-based framework for representing and manipulating knowledge during Computer-Aided Architectural Design. The framework incorporates a meta-level architecture to represent declarative design knowledge and strategic knowledge used by the designer. It consists of an object layer, a design requirements layer and strategies for navigating through the design space. An extended first-order logic is described which has been used to represent some examples of architectural knowledge. This computational model is being implemented in KAUS (Knowledge Acquisition and Utilisation System), a general purpose knowledge-based system, founded in Multi-Layered Logic.

summary The rapid development of the potentialities of multimedia imposes a reflection about its use in teaching architecture. Multimedia is multifaceted and each facet deserves a particular attention inasmuch as it can change the traditional approach to learning. A direct experience of an architectural work can be simulated with a impact far stronger than an experience trough photographs, drawings and books can do. But, as every positive fact can have in certain cases also some negative consequences. the intensity of the participation to an experience structured by someone else can leave less space to a personal approach to the object of the presentation. The same problem is posed if we consider the structure of an hypertext. The essence of the hypertext lies in the net of relationships between very different kinds of documents that it is able to manage in order to express the complexity of its theme. But who has to create the net, the teacher choosing the relationship that he thinks important or the learner to build a personal image of the hypertext matter. It is an old question about the two faces of teaching: transmitting knowledge or giving the learner the instruments to build by oneself his store of knowledge. Easy and trivial answer that both approaches can be useful. The accomplishment of a multimedial sequence of average complexity requires at present a lot of time. Hence, to be convenient, it is to be used many times, then by many students. The effectiveness of the tool partly depends on the rapidity with which it can be constructed. Speeding it up would allow to use this kind of tools with the same easiness than mare traditional means of representation. Besides those general considerations a check is to do on the peculiarities, if any, of the use of multimedia in the different disciplines of the formative curriculum of an architect. This is theme of our thirteenth conference. The programme has been articulated into sessions, dealing separately with history teaching, design teaching and research. Of course the sessions dealing with design are more numerous than the other, since design is the axis of teaching architecture. The presented paper cover a large arc of arguments, dealing with many facets of the proposed themes with plenty of examples and documentation on practical experiences. constituting a corpus of great usefulness for any operator in the field of architectural teaching.
