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.

title Providing a Structured Method for Integrating Non-Speech Audio into Human-Computer Interfaces
source Heslington, York: University of York
summary This thesis provides a framework for integrating non-speech sound into human-computer interfaces. Previously there was no structured way of doing this, it was done in an ad hoc manner by individual designers. This led to ineffective uses of sound. In order to add sounds to improve usability two questions must be answered: What sounds should be used and where is it best to use them? With these answers a structured method for adding sound can be created. An investigation of earcons as a means of presenting information in sound was undertaken. A series of detailed experiments showed that earcons were effective, especially if musical timbres were used. Parallel earcons were also investigated (where two earcons are played simultaneously) and an experiment showed that they could increase sound presentation rates. From these results guidelines were drawn up for designers to use when creating usable earcons. These formed the first half of the structured method for integrating sound into interfaces. An informal analysis technique was designed to investigate interactions to identify situations where hidden information existed and where non-speech sound could be used to overcome the associated problems. Interactions were considered in terms of events, status and modes to find hidden information. This information was then categorised in terms of the feedback needed to present it. Several examples of the use of the technique were presented. This technique formed the second half of the structured method. The structured method was evaluated by testing sonically-enhanced scrollbars, buttons and windows. Experimental results showed that sound could improve usability by increasing performance, reducing time to recover from errors and reducing workload. There was also no increased annoyance due to the sound. Thus the structured method for integrating sound into interfaces was shown to be effective when applied to existing interface widgets.

summary CAD-programs belong to the most complex kinds of software - complex and difficult in using and especially in learning for architects and for students. Some years ago we already tried to find ways for making the first steps easier for students and more comfortable for teachers: Our first attempt was to reduce the number of commands from 150 to only 20 in the first lesson by cutting off many of the pull-down-menus (it was even the time before the cad-program, we use, was running under windows). We supported the reduced menus on the screen by handing out a template with all the needed commands for the first lesson. We had two positive results: the first was a reduction of beginners frustrations about too many new things, the second was a homogenisation among the students´ know how: the very eager ones were no longer able to test too many new things! In the second lesson the students got another twenty new commands and so on (they could start the program with a batch rib-1, rib-2 etc.). Our second attempt was the development of new dialogues due to our experience in teaching and in looking at the same points of difficulties every year.

summary What is the role of CAAD as a tool of architectural form creation ? We used to over-estimate the role of computer as significant factor of design process. In fact it serves only to produce technical documentation and to visualise designed buildings. We usually use CAAD to record ideas, not to create designs. We use it like more complex pencil. But it is unsuitable for conceptual design , with imperceptible influence on idea definition. Its practical usefulnes is limited. I would like to consider and find out reasons of that state, present some conclusions and ideas on computer aided architectural form creation. Many tools were invented to extend posibilities of human body or intellect. Microscop and telescop are extensions of human eye. Which organ is extended by computer (especially by CAAD)? CAAD with high developed function of visualising of the object beeing designed seems to be an extension of architect's imagination. It is beeing used to foresee visual efects, to check designed forms, to see something what we are not able to imagine. It performes the role of electronic modeler. Real model and virtual model - the medium of presentation is diferent but ways of using them are similar . Dislocation of place where we build model is not a big achievement, but potential possbilities of CAAD in modeling are almost unlimited (?). What are special features of CAAD as a modeling tool? First we have to consider what is indispensible when building a model: to embody idea. To do this we need space, substance and tools. In architectural design practice space is a real site with definite climate, neigbourhood, orientation. Substance that we shape is an archiectural form composed of many difrent elements: walls, windows, roof, entry, ... , proportions, rhythm, emotions, impresions... The tool is: our knowledge, imagination, talent, experience, norms, law and drawing equipment. Working with the computer, making virtual model, we have many of mentioned elements given in structure of CAAD program and interpreted by it. But many of them have different character. Making traditional dummy of building we operate on reality which is manually accessible. In case of computer model we operate on information. Space, substance and tool (- program) are informations, data. Human being is not an abstract data processor, but creature that lives non stop in close, direct, sensual contact with nature. By this contact with enviroment collects experiences. Computer can operate on digital data that is optionally selected and given by user, independent upon enviromental conditions. Usually architecture was created on basis of enviroment, climate, gravity. But these do not exist in CAAD programs or exist in the symbolic form. Character of these conditions is not obvious. We can watch demeanour of objects in gravity but it can be also antigravity. In theory of systems everything is considered as a part of biger system. In "virtual" reality (in computer space) we deal with accurences which are reduced to abstract level, free upon terms or connections. We work with our CAAD software using geometric space whithout any other principle.

summary The work described here is aimed at contributing towards the debate and development relating to the construction of interfaces to explore buildings and their environs through virtual worlds. We describe a particular hardware and software configuration which is derived by the use of low cost games software to create the Virtual Environment. The Physical Interface responds to the work of other researchers, in this area, in particular Shaw (1994) and Vasquez de Velasco & Trigo (1997). Virtual Evironments might have the potential to be "a magical window into other worlds, from molecules to minds" (Rheingold, 1992), but what is the nature of that window? Currently it is often a translucent opening which gives a hazy and distorted (disembodied) view. And many versions of such openings are relatively expensive. We consider ways towards clearing the haze without too much expense, adapting techniques proposed by developers of low cost virtual reality systems (Hollands, 1995) for use in an architectural setting.

summary Twenty years of revolution, from the middle '70 to the middle '90. Many things have changed since the origins of computer graphics and computer aided design in architecture. We started teaching drafting on terminals which connected to mini computers, complex procedures or sets of graphics libraries working with keywords, vectors and storage screens. The next step was devoted to the discovery of workstations in the early '80's, where the user sat face on to the whole power of a multitasking system. At that time to use up to 16 time sharing processes running on the same work station seemed to have no practical use at all. Fortunately someone (ie Xerox PARC laboratories) at the same time started to develop the so-called GUI. Graphical user interface started a revolution in human/machine interface (ie Smalltalk). The desktop metaphor, the use of multiple windows and dialogues joined with icons and pop up menus let the user manage more applications and, even more important, created a standard in application/user interface (CUA). In the meantime focus had moved from hardware to software, systems being chosen from the software running. The true revolution we have seen starting from that base and involving an ever increasing number of users was the birth of PC based applications for CAAD. Generally speaking nowadays there are three main technologies concerning teaching: communication, multimedia and virtual reality. The first is the real base for future revolution. In the recent past we have started to learn how to manage information by computers. Now we can start to communicate and share information all over the world in real time. The new age opened by fax, followed by personal communication systems and networks is the entry point for a real revolution. We can work in the virtual office, meet in virtual space and cooperate in workgroups. ATM and ISDN based teleconferencing will provide a real working tool for many. The ever increasing number of e-mail addresses and network connections is carrying us towards the so called 'global village'. The future merger between personal digital assistant and personal communication will be fascinating. Multi & HyperMedia technology is, like a part of VR, a powerful way to share and transfer information in a structured form. We do not need to put things in a serial form removing links because we can transfer knowledge as is. Another interesting and fundamental aspect typical of VR applications is the capability to change cognitive processes from secondary (symbolic - reconstructive) to primary (perceptive - motory). In this way we can learn by direct experience, by experiment as opposed to reading books. All these things will affect not only ways of working but also ways of studying and teaching. Digital communications, multimedia and VR will help students, multimedia titles will provide different kinds of information directly at home using text, images, video clips and sounds. Obviously all those things will not substitute human relationship as a multimedia title does not compete against a book but it helps.

title A Visualization Model for External Shading Devices Performance at the Early Design Stage
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Windows are used for the visual connection between indoors and outdoors, ventilation and daylight of our interiors and for the reduction of our heating energy through solar energy utilization. This solar energy, however, is often so intense that counter measures should be taken in order to maintain comfortable indoor conditions. Air conditioning is one counteraction. In order to reduce the cooling loads, it is highly recommended to use shading devices. When shading devices are applied in combination with the glass they can modify the thermal effect of windows to a very great extent. The most effective shading devices are exterior types such as overhang, fins and exterior venetian blind. The effectiveness of an external shading device depends on its geometry, sun path, and the orientation of the building. These factors are interrelated dynamically, it is extremely difficult to predict intuitively how the shadow is cast by the external shading device on the window. Due to the inherent complexity of calculation for shadow casting, building designers to fail often integrate them into energy-efficient building design. Since computer graphics can be a powerful visual communication tool, the above problem might be solved through a computerized graphical interface in the early design stage. The research described in this paper involves the development of a computer program which aims the following objectives: (1) to facilitate the description of a external shading device's geometry through an integrated graphic input model, (ii) to simulate the relationship of external shading devices and shadows based on sun path, the orientation of building, (iii) to visualize the shadow casting by shading devices, and (iv) to provide designers with possible solutions to create energy-efficient external shading device for a specific building.

summary The design of masonry, tile, and ceramics is an integral part of architectural history. High fired clays are unique in that they are amorphous, vitreous, and translucent. Similar types of light transmission through minerals and clays has been achieved in window panes using alabaster or marble, but unlike porcelain these cannot be cast, and they are susceptible to moisture. Additionally, glass and metal are commonly used to glaze ceramics, and this provides further possibility for the combination of translucency with surface ornamentation and decaling. It is within this architectural lineage, of compound stone and glass objects, that the Dunejars are situated. The Dunejars are translucent porcelain vessels that are designed as lenses to transmit different wavelengths of light into intricate and unexpected patterns. Similar recipes for porcelain were developed using wax positives during the 19th century to manufacture domestic Lithophanes; picturesque screens made of translucent porcelain, often displayed in windows or produced as candle shades (Maust 1966). The focus of the research involves pinpointing the lithophanic qualities of the clay so that they can be repeated by recipe, and refined through a digital workflow. The methods outlined here are the product of an interdisciplinary project residency at The European Ceramic Workcenter (Sundaymorning@EKWC) in 2018 to make tests, and obtain technical precision in the areas of, plaster mold design, slip-casting, finishing, firing, and glazing of the Dunejars. The modular implementation of these features at the scale of architecture can be applied across a range of scales, including fixtures, finishes and envelopes, all of which merit further investigation.

source Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 31-40
summary Space simulation is a technique employed by architects, urban designers, environmental psychologists and other related specialists. It is used for academic and research purposes, as an aid to evaluate the impact that the built environment or that to be built would yield in potential or real users. Real Scale Model is organized as one of the models which represents more reliable spatial characteristics in space simulations. However, it is necessary to know the ecological validity of the simulations carried out, that is the degree in which laboratory results could be taken as reliable and representative of real situations. In order to discover which variables of the model used are relevant so that their perception results ecologically valid in respect to reality, a research has been designed in which simulations of specific spaces are appraised both in real space and in the real scale model. The results of both evaluations were statistically analyzed and it shows no significative differences in psychological impressions between the evaluation of real spaces and real scale model. These ecological validation of the real scale model could be of great use to estimate the validity of the results obtained in spaces simulated in the laboratory.

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 The paper describes how a specially written customisation of AutoCAD enables students of Architecture to use the method of spatial analysis called Space Syntax developed by Professor Bill Hillier of the Bartlett School of Architecture, London, to examine a number of existing museums, to compare the findings against other criteria, and to draw conclusions about the strategy adopted in museum design. Simple interactive graphics enable plans to be entered and compared, so that they may be evaluated during the design process, with decisions supported by objective tests. This improves both design decisions and the learning process.

title A run time exchange of component information between CAD and object models: A standard interface
source The Int. Journal of Construction IT 2(2), pp. 37-52
summary Integrated computer aided design could only occur in engineering once CAD systems could represent physical features and components rather than graphical primitives. In most dedicated CAD systems, the knowledge of a complete component exists only for the duration of each drawing command and the data stored in the database is simply a set of graphic primitives. This paper proposes an approach for real time information transfer from and to CAD systems based on a high level object representation of the design drawing. Drawing components are automatically identified and represented in an object hierarchy that reflects the 'part-of' relation between the various components including building spaces. Such hierarchies transfer an industry standard CAD system i.e. AutoCAD, into a high level object oriented system that can communicate with external applications with relative ease.

title Determining the impact of cad drafting tools on the building delivery process
source The Int. Journal of Construction IT 2(1), pp.1-8
summary Computer aided design is intended to change the way design and construction are carried out. at a minimum, this implies savings realized in terms of time spent and improvement of the quality of designs produced. to test this idea, we hypothesized that computer aided drafting and design operations may be instrumental in reducing the number of change orders issued and help control cost overruns by improving the accuracy of construction documents. we compared change orders in projects designed in the conventional media against ones developed with computers. we found that there is evidence supporting our hypothesis. furthermore, in the process of investigating this question, we found that computer applications to improve the management of existing building information (as-built drawings, building system related information, and the like) represent even more critical needs than those that can reduce change orders through more accurate design drawings.

source Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 59-70
summary This paper discusses the possibility of applying full-scale modelling in Vietnam, a non-western so called developing country. It deals with two main questions: 1) Is the application of full-scale modelling to be restricted to the West only? 2) what are the possibilities, constraints and fields of application - with attention to the methodological validity and technical solution for full-scale modelling in Vietnam? It is argued that since full-scale modelling is based on people-environment interaction, it should, in principle, apply to studies about people–environment relation anywhere on earth. On the methodological validity, it is discussed that application of full-scale modelling in Vietnam faces similar methodological problems as encountered in European applications (such as people's behaviour in experiment, ability to understand the abstraction of models, etc.) although at another level as this paper will make clear. However, it would be needed to design a modelling kit that is of low costs and adapted to the availability of local materials and suitable for the climatic condition of Vietnam. Two fields of application are projected as most applicable in Vietnam: modelling in architectural education and research investigation. Application for user's participation in the design process will depend on the development of building policy in the country.

summary This paper describes the design of a DSS for locating facility networks. The proposed DSS is based on the principle of dynamic data definitions. The declarative and procedural forms of knowledge involved are identified by a logical analysis of planning tasks. The DSS supports an iterating process of adjusting and evaluating plan options. A flexible and interactive problem solving environment is achieved by means of a user defined set of views that captures both forms of knowledge. Each view describes the system to be planned in terms of a set of variables and attached evaluation procedures. The views are dynamic and linked data structures, so that changes in one view automatically lead to updating all linked views. The DSS supports both the specification of the set of views and its application to solve a specific location problem.

source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Recently, a number of interesting extensions to traditional decompositional and discrete choice models has been introduced that allow one to combine parameters estimated in different phases ofcomplex choice processes. These extensions offer new possibilities to model combinations of choices consumers make if they select shopping centres to visit. This paper will introduce a modelling approach that describes consumer choices of shopping centres involving multiple shopping functions (multi purpose) as well as locations (multi stop). The approach extends traditional decompositional models of single choices to a model of combinations of choices. It uses a recursive scaling procedure that combines attributes related to different shopping functions and to shopping centres at different locations. The model will be tested on data collected on shopping behaviour in Maastricht, the Netherlands.

title Form Characteristics of Landscape Images: A Landscape Research by Computer Image Processing
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Landscape evaluation research examines how individuals perceive the landscape. Because the amount of the data to describe landscapes is huge, landscape research needs the technology of the computer. This paper describes a method to catch the amount of physical characteristics which were extracted from landscape images by using the technology of the computer image processing and verifies its effectiveness. To do this analysis, we took photographic slides of a landscape sample. Pictures were taken for three regions (the city centre area, the outskirts area, and the farm village area). The number of slides was 6 for each place hence 18 in total were used for theanalysis. Next, we stored these slides on a computer disk. Form characteristics of the landscape elements were extracted by using computer image processing. Borderlines were extracted usingthe algorithm of Robert and were converted into coordinates data by minute line processing and the vector processing. Other elements were extracted by label processing and were converted into the coordinates data by vector processing. These data thus are the vector data for two-dimensions of the image and not the data for a three-dimension space. The processing of these images enables the analysis of the form characteristics in the landscape images. We calculated the data such as appearing length, angle numbers of appearance of the vector data, and analyzed the characteristic of shape and the complexities of landscape applying fractal theory. We compared three districts and were able to find landscape characteristics of various places as a result.

summary In the architectural creation process there has always been an inclination to improve the methods of designing in the way of ,,objectivization" of designing process. Objectivization which would explain why we do design in this way and not the other. In spite of the trend to the total objectivization (Vitruvius, Alberti, Palladio), the results appeared to be still subjective, i.e. they included methods of designing typical of the one and only architect. This fact made them completely useless in the designing practice. On the other hand one cannot underestimate their meaning as to this very practice. Because it is just thanks to them that the development of designing studies has taken place. We do learn not only watching works of great architects, but also studying their opinions concerning problems of form, function and construction. That is why it seems to be useful to collect experiences concerning the classic theory of architectural composition, which have been gathered through centuries, as well as to try once again to objectivize the process. Composition information arranged in the form of data-base would create the ground for proper functioning of an expert system uniting diagnostic and planning functions. Study of that kind, not claiming design applications could be an excellent educational equipment in teaching architectural composition. In the proposed teaching system attempts have been made to look at the architectural composition theory in the light of the perception of the form, and - emerging in this process - emotional and aesthetic evaluations. In order to define which evaluations have been most often expressed during the perception process of architectural forms, the students of Architecture Faculty in Bialystok Technical University have been polled on the subject: ,,Which words are most commonly used in the descriptions of architecture works?"
