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 introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

summary	The need for regional styles to exist in architecture has been broadly and long discussed. In general, regionalisms are socially accepted and they should be employed. Discussions usually become more intensified together with the search for inspiration to create new styles in architecture. In Poland Stanislaw Witkiewicz, arts critic and theoretitian, a painter and a writer, created and developed “the Zakopane style” on the turn of the 19th century. This is the only one architectural style focussed on the regional features that has been preserved until nowadays. It referred both to architecture and industrial forms. It was received by the contemporaries with ambivalent attitude, from the uncritical enthusiasm to emotional negation. One side claimed that the style affected the national consciousness and united the nation without the State. According to the other side, “the Zakopane style”, when outside the Podhale region, shocked with its non-conformity to the surroundings. About 1910 there was an attempt to create the style not exactly regional but rather national. The designs referred to neoclassic Old Polish mansion house with a porch supported by columns and high mansard roof. Between 1915 and 1918 projects to rebuild the Polish villages and little towns were thrown open to competition. Afterwards, neatly published project catalogues presented universal, all-Polish type of architecture. In 1918, after I World War and after Poland regained independence, whole housing estates were built in manorial style. At the same time the described sets of competition projects were used together with the new ones, prepared by eg. Polish Hygenic Society (1936). All the project proposals show the all-Polish type of regionalism. Another intensification of discussion concerning the regional style is linked with the post-modernist ideas. Modernism-lacking ornament, cosmopolitan, without any homely features (by the way, he is jolly smart who knows what this “homeliness” is all about) despite its undeniable achievements has been finally faced with crushing criticism. Together with this reaction the search for inspiration in regional features of architecture has been revived. But then there has been a lack of Witkiewicz’s enthusiasm and stubbornness. We deal with constant attempts to solve the problem of creation in regional style. The situation described allows for the statement that there are two forms of regionalism: one on a narrow, territorial and second on the all-Polish scale. No doubt, “the Zakopane style” was the territorial regionalism, and the manorial architecture-the all-Polish one. The condition and quantity of traditional forms are really varied in Poland. For these still existing objects to serve as “model” and inspiration, they have to be examined, classified and made accessible to the designers. The next step is to extract the most distinct features of sub-regions and to popularize the knowledge of these problems. At the Faculty of Architecture of Bialystok Technical University the relative data base concerning the regional architecture is being created on the basis of Microsoft’s ACCESS. It is still another attempt to preserve and uphold the cultural landscape of Poland.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	A Strategic Planning and Policy Decision Support Tool for Urban Regions
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In this paper we present a Decision Support System developed to assist urban designers, planners and policy makers to explore and evaluate possible urban layouts and their growth patterns. Thecore of the system consists of a modelling shell allowing the user to specify cellular automata based models of urban and regional systems. These models capture the effect of local spatial processes in which the use, or desired use of each parcel or cell of land is determined partly by institutional and environmental factors, and partly by the activities present in its neighbourhood. Since each cell affects every other cell within its neighbourhood, a complex dynamic emerges. Unlike conventional cellular automata, the models are defined with a large neighbourhood --over a hundred cells-- a relatively large number of states --more than a dozen in some applications-- representing socio-economic and natural land-uses. The approach permits the straightforward integration of detailed physical, environmental, and institutional constraints, as well as including the effects of the transportation and communication infrastructure. These models thus permit a very detailed representation of evolving spatial systems. The current version of the system represents urban areas as consisting of up to 10.000 interacting zones, each roughly the size of an individual city block. These models are easy to build and apply, yet empirical tests show that they produce realistic simulations of urban land use dynamics. Consequently, they are well suited to form the heart of the DSS, which provides the user with a number of tools for exploration,analysis and evaluation of alternative futures of the system as they result from policy interventions that are imposed by means of what-if experiments and scenario analysis. For example, the DSS isable to identify areas in which pressure for change in land use restrictions may become critical under particular development strategies. In the DSS, the modelling shell is coupled to a simple,custom-built GIS. In the stand-alone application of the DSS, this stores the detailed geographical qualities of the area being modelled, and allows basic overlay manipulations. It also displays theresults of the model while the simulation proceeds. Alternatively, the GIS can serve as aninterface to more elaborate, commercial GIS systems.

title	Analysis of design communication with and without computer mediation
source	Proceedings of Co-designing 2000, pp. 329-337
summary	With recent developments in CAD and communication technologies, the way we visualise and communicate design representations is changing. A matter of great interest to architects, practitioners and researchers alike, is how computer technology might affect the way they think and work. The concern is not about the notion of 'support' alone, but about ensuring that computers do not disrupt the design process and collaborative activity already going on (Bannon and Schmidt, 1991). Designing new collaborative tools will then have to be guided by a better understanding of how collaborative work is accomplished and by understanding what resources the collaborators use and what hindrances they encounter in their work (Finholt et al., 1990). Designing, as a more abstract notion, is different than having a business meeting using video conferencing. In design it is more important to 'see' what is being discussed rather than 'watch' the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the method with which it is communicated (See Kvan, 1994). Similarly, we believe that by using text instead of audio as a medium for verbal communication, verbal representations can then be recorded alongside graphical representations for later retrieval and use. In this paper we present the results of a study on collaborative design in three different environments: face-to-face (FTF), computer-mediated using video conferencing (CMCD-a), and computer-mediated using "talk by typing" (CMCD-b). The underlying aim is to establish a clearer notion of the collaborative needs of architects using computer-mediation. In turn this has the potential in assisting developers when designing new collaborative tools and in assisting designers when selecting an environment for a collaborative session.

title	What Conceptual Modelling Is and Isn´t
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	It is generally agreed that conceptual modelling is an important activity in the development of knowledge based systems. The availability of an adequate conceptual model is of vital interest notonly for the design and implementation of knowledge based systems, but also for their validation, modification, maintenance and enhancement. In order to be able to develop adequate conceptualmodels a theory about the nature of knowledge is required and, in line with this theory, a methodology to reconstruct the meaning of concepts. Additionally, techniques have to be selected which enable the modelling, representation, validation and simulation of reconstructed concepts. In the development of knowledge based systems often techniques are used which are not very wellsuited to the reconstruction and representation of the concepts of an application area. The selection of a technique is not motivated by an explicitly formulated theory, but by the representation formalisms applied within the software used for the implementation of knowledge based systems. This often leads to inadequate conceptual models and consequently poorly functional and hardly maintainable systems, mainly because the representation of concepts is adapted to the limitations of the applied representation formalism. In this paper we explain how the conceptual modelling activity isusually tackled in thedevelopment of knowledge based systems and what the related problems are.

title	Visual Reference for Design: Analogy, Transformation and the Act of Sketching
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	All designers know that it is impossible to infer a design solution from the givens of a task alone, no matter how complete and well presented they are. Therefore, designers seek to complementinformation they receive, and the material they bring into the task environment includes visual images. Images may be gathered from every imaginable source, from domain-specific images (in architecture they are usually classified and pertain to building type, location, period, technology, style or creator) through 'metaphoric' images (art, nature) to eclectic personal favourites. Inaddition, randomly encountered images may find their way into a database of references: a depository of potentially useful images. With the exception of factual information that fills in thetask givens, it is usually far from clear what purpose may be served by images in general, or to what use the specific images aligned for a particular task may be put. We propose that the singlemost significant 'on line' role of visual references during the process of designing is to suggest potential analogies to the entity that is being designed. The process of discovering and exploitingan analogy in design is complex; we shall explain it in terms of Gentner's structure mapping theory, which we adapt to visual structures. We further propose that the abstraction process thatmust take place for the successful identification and mapping from source (visual reference) onto target (designed entity) requires transformations of images, and such transformations are bestachieved through sketching. Sketching facilitates the two way process of movement from the pictorial to the diagrammatic and from the schematic to the figural. Such transformations musttake place to arrive at the match that allows conceptual transfer, mapping of structural relations and insight through analogy.

title	Indexing the Electronic Sketchbook: Diagrams as Keys to Visual Databases
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The question is how to index a visual database. Consider a visual database -- collection of drawings, three-dimensional models, scanned photographs, video, and text -- as a kind of modernmultimedia architectural sketchbook. It can be shared among a wide group of users with different purposes, and who may think about the contents in rather different ways. The connections -- perhaps hypertext -- among the entries may be complex and the organization difficult to comprehend. How then, to index the collection? Certainly traditional techniques -- looking for a concert hail -- built of concrete and glass -- in the 1970's in Utrecht and the architect's name is H* -- will help. But suppose we do not know so precisely what we are looking for? Might we appeal to the language of diagram? Can we add to our schemes for search and retrieval a diagrammatic index? We propose to try this idea. The paper describes our "computer as cocktail napkin" system for recognizing and interpreting diagrams. It consists of a pen-based freehand sketching program that recognizes simple symbols the user has trained (such as lines, shapes, letters, etc.) and spatial arrangements of these symbols. A graphical search procedure finds occurrences of a drawn configuration of symbols in the pages of a sketchbook made using the program. By extending thepages of the sketchbook to include photos, drawings, and text in addition to diagrams, we can use this technique to find items whose diagrams match a drawn search configuration. The paper will demonstrate this prototype program and explore its use for indexing visualdatabases in architecture.

title	Control of Parts: Identifying Patterns of Control in Production Chains
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	If we examine the stages of production of complex physical systems, we notice that parts change as they progress along a value chain. Parts are deformed, have parts removed, and are assembled and disassembled, in various sequences. In such processes, production operations (milling, cutting, aligning, attaching, and so on) are of particular interest, as are the sequences of production, since some operations and sequences have been found to be more efficient than others, lead to fewer mistakes and produce higher quality results. Research continues to be produced seeking to optimize production operations, sequences and product quality. The production operations we can observe in the making of artifacts are also of interest because they are by definition the result of action taken by certain agents. Parts are changed or controlled by human beings, employing their own hands or sophisticated machines. Today, we are used to making a distinction among agents involved in production: some agents specify what is to be made, and others make what is specified. One agent can do both, but specialization and division of labour has presented us with this distinction. This is now conventional, aside from whether it is "good" or not. The distinction is the basis for the interest in "concurrent design and production of products", the renewed focus on distribution and coordination of work in teams, and the related interest in understanding the dynamics of building systems in terms of the agents who control them. This paper focuses on the place certain kinds of agents take in complex production flows. Since production of parts is both a technical and a social enterprise, we will discover, when we look closely, complex webs of interactions which can be mapped, showing how agents relate to each other through the parts with which they are concerned. In examining the class of agents who control parts, we can see two patterns of control, termed DISPERSED PATTERNS and OVERLAPPING PATTERNS. These become palpable in a graphic diagramming tool, which is demonstrated in what follows. These diagrams also provide a means to consider the agents whose role is to specify what is to be made. The paper includes notes related studies in other fields.Finally, the paper suggests how this perspective can be useful, and several research topics based on it are sketched.

doi	https://doi.org/10.52842/conf.ecaade.1999.431
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.

title	Some Phenomena of seeing shapes in design
source	Design Studies, v 16, n 3, pp. 367-385
summary	This paper is a look at some of the pyschological results that suggest how shape emergence manifest itself in the human mind. The first interesting result goes back to top down expectation guiding recognition. Some experimental suggest that it is easier (quicker) to recognize shapes which we have some alternate mental familiarity. (I.E. verbal, structural descriptions). So if we can easily say a shape then we can easily discern it as an emergent shape. The paper then goes on to discuss the definition of emergent subshapes and gives various authors definitions of what makes up and emergent shape. One interesting classification is the difference between explicit and implicit emergent shapes made by Mitchell. This difference amounts to a fine line between imagination and emergence. The results of an experiment between experienced and in-experienced designers is discussed. The results suggest that experienced designers are able to find more emergent shape than non experienced designers. From these results and from the opinions of others, the author goes on to specify 3 phenomena related to emergent recognition. The first is as above that it is easier to see shapes with which we are familiar. Second from this, the harder shapes are found after the initial period. Third, from the first two, time is required to find more subshapes. The author then searches for an explanation of this phenomena. He suggests that the underlying cause is related to an experience person having a lower threshold of what it is to be a member of a shape. When seeing an L shape the experienced design is likely to consider it also a square, because his requirement for the set of features which must be present for some object to be a considered a square is a smaller set than the inexperienced. While the author suggests that this is a phenomena it is actually an hypothesis. An alternate hypothesis may be that top down inhibitions effect the bottom up performance of the inexperienced design more because of different representation.

title	An Overview of the PHIDIAS II HyperCAD System
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 63-74
doi	https://doi.org/10.52842/conf.acadia.1994.063
summary	The PHIDIAS II HyperCAD system combines the functionality of CAD graphics, hypermedia, database management and knowledge-based computation in a single, highly integrated design environment. The CAD functionality includes both 3-D and 2-D vector graphics. The hypermedia includes support for text, raster images, video and sound. The database management enables persistent storage and interlinking of large collections of text, images, video, sound and vector graphics, i.e., thousands of vector graphic objects and drawings in a single database. Retrieval is provided both through use of "associative indexing" based on hyperlinks and through use of an advanced query language. The knowledge- based computation includes both inference and knowledgebased critiquing. A highly unusual feature of PHIDIAS II is that it implements all of its functions using only hypermedia mechanisms. Complex vector graphic drawings and objects are represented as composite hypermedia nodes. Inference and critiquing are implemented through use of what are known as virtual structures [Halasz 1988], including virtual links and virtual nodes. These nodes and links are dynamic (computed) rather than static (constant). They are defined as expressions in the same language used for queries and are computed at display time. The implementation of different kinds of functions using a common set of mechanisms makes it easy to use them in combination, thus further augmenting the system's functionality. PHIDIAS supports design by informing architects as they develop a solution's form. The idea is thus not to make the design process faster or cheaper but rather to improve the quality of the things designed. We believe that architects can create better buildings for their users if they have better information. This includes information about buildings of given types, user populations, historical and modern precedents, local site and climate conditions, the urban and natural context and its historical development, as well as local, state and federal regulations.

title	Craft and Geometry in Architecture: An Experimental Design Studio Using the Computer

summary	Craft is one of the main aspects of architecture that accounts for its strong corporeal presence. The Computer used as a geometry machine lacks such tectonics. The predominant means for bringing a sense of materiality to its geometric constructions is through rendering, and in this respect the computer is not significantly different from geometric drawing. One need only recall the beautifully rendered drawings of the Beaux-Arts for a comparison. With the rise of modern architecture such 'paper' architecture was voraciously denounced in the cause of relating architectural production more closely with crafted production. Even now the interest in craft has persisted despite postmodern criticism. Therefore, a means for bringing a greater sense of craft to computer-aided design seems desirable. The architectural studio discussed in this paper was initiated partly for this purpose by intentionally confronting the computer's proclivity to move its users away from craft toward geometry, while at the same time taking advantage of its capabilities as a geometry machine. Craft can best be understood by practicing it. Consider, for example, the use of a chisel in woodwork. As one applies force with it, one can feel the resistance of the material. Carving with the grain feels differently than carving against or across it. Carving a piece of maple feels differently than carving a piece of pine. If one presses too hard on the chisel or does not hold it at the precise angle, there is a great risk of creating an unwanted gouge. Gradually with practice the tool feels as if it is an extension of the hand that holds it. it becomes an extension of the body. One can feel the physical qualities of the wood through it. Like a limb of the body its presence can become transparent and one can learn about what one feels through it. It can imprint a memory in the mind that comes to the brain, not through the eyes alone, but through the tactile senses. On the other hand it is tiring to use a chisel for an extended period of time. One's body begins to ache and, as the body tires, the risks of making an unwanted mistake increase. Furthermore, because a tool becomes wedded to the body, it is almost impossible to use more than one tool at a time unless they are being used in conjunction with one another as one might use two limbs of the body together. On a computer one can never 'feel' an object, the image of which is on the screen, in the same manner that one can feel with a chisel the material upon which one is working. One becomes particularly aware of this when creating a 3D computer model of a hand tool. One wants to hold it, not just look at it. Thus the artifice of the object created by means of the computer becomes very apparent, because the 'tool' has not yet taken on the qualities of a tool, although it has taken on the appearance of one.

title	"To See Ideas" or The Visualizing of Programmatic Data Reading Examples in Architecture and Town Planning
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Whether images are still in the mind, metaphors, sketches or icons, they play a crucial role. They have always been the heuristic pivot around which the process of artefact design organizes itself, particularly in architecture and town-planning. "To see ideas" through computer ideograms is to experiment an interesting and new direction for "pictural approach" supported design. Cognitive psychology emphasizes the important part played by mental images in reasoning, imagination in the working of human intelligence and the construction of mental images as cognitive factors underlying reasoning. It also points out how close computerized objects and mental schemata are. "To reason over a situation is first to remember or build some mental models of this situation; second to make those models work or simulate them in order to observe what would happen in different circumstances and then verify whether they fit the experiment data; third to select the best model, a tool meant to sustain and amplify the elaboration of mental models, which is a spontaneous activity". We introduce our exploration of the direct transmission of mental models through computer ideograms. We study the "operative" and the "expressive" aspects, and this allows us to analyze how some aspects in a field of knowledge are represented by ideograms, schemata, icons, etc. Aid to imagination, reasoning and communication by means of a graphic language must be limited to some figurative relevant aspects of the domain considered; it should not aim at a realistic simulation. Therefore, the important role played by icons and the spatial schematic representation of knowledge is emphasized. Our hypothesis is that an architectural concept does not result from an inductive process, but rather is built to solve problems through the direct representation of ideas with ideograms. An experiment was conducted with a graphic language, a dynamic scenography and actor-objects. The language allows one to build and visualize models from the various domains of knowledge of the object. The dynamic scenography can explore and simulate kinetically those models by means of staging various narrations and visual scenarios. The actor-objects play various and complementary parts in order to make the image explicit and link it with the concept. We distinguish between two parallel levels of reality in computer ideographics: one concerns the model, it represents the visualization of a graphic model at a particular moment and according to a particular representation, the other concerns the ideogram.

summary	After having conducted a Digital Media based design studio at Cal Poly for six years, we have developed a body of experience I feel is worth sharing. When the idea of conducting a studio with the exclusive use of digital tools was implemented at our college, it was still somewhat novel, and only 2 short years after the first VDS- Virtual Design Studio (UBC, UHK et.al.-1993). When we began, most of what we explored required a suspension of disbelief on the part of both the students and faculty reviewers of studio work. In a few short years the notions we examined have become ubiquitous in academic architectural discourse and are expanding into common use in practice. (For background, the digital media component of our curriculum owes much to my time at Harvard GSD [MAUD 1989-91] and the texts of: McCullough/Mitchell 1990, 1994; McCullough 1998; Mitchell 1990,1992,1996; Tufte 1990; Turkel 1995; and Wojtowicz 1993; and others.)

title	Why Architects Draw
source	The MIT Press, Cambridge, Massachusetts
summary	For nearly twenty years Edward Robbins, an anthropologist, has been studying and writing about the system of architectural education and practice in the United States and abroad. In this book he examines the social uses of architectural drawing: how drawing acts to direct both the conception and the production of architecture; how it helps architects set an agenda, define what is important about a design, and communicate with their colleagues and clients; and how it embodies claims about the architect's role, status, and authority. The centerpiece of Robbins's provocative investigation consists of case study narratives based on interviews with nine architects, a developer-architect, and an architectural engineer. The narratives are illustrated by the architects' drawings from projects in Japan, England, Italy, Germany, Spain, Portugal, and the United States, from conception through realization. Included are orthographic and axonometric projections, perspectives, elevations, plans, sections, working drawings, sketches, schematics, construction, and finished drawings. Drawings and interviews with: Edward Cullinan, Spencer de Grey, Jorge Silvetti, Renzo Piano, Alvaro Siza, John Young, Itsuko Hasegawa, William Pedersen, Rafael Moneo, Rod Hackney, Peter Rice.

title	A Perceptually- Supported Sketch Editor
source	Proc. UIST 94, Marina del Rey, CA 175-184
summary	The human visual system makes a great deal more of images than the elemental marks on a surface. In the course of viewing, creating, or editing a picture, we actively construct a host of visual structures and relationships as components of sensible interpretations. This paper shows how some of these computational processes can be incorporated into peneptuallysupported image editing tools, enabling machines to better engage users at the level of their own percepts. We focus on the domain of freehand sketch editors, such as an electronic whiteboard application for a pen-based computer. By using computer vision techniques to perform covert recognition of visual structure as it emerges during the course of a drawingkditing session, a perceptually supported image editor gives users access to visual objects as they are perceived by the human visual system. We present a flexible image interpretation architecture based on token grouping in a multiscale blackboard data structure. This organization supports multiple perceptual interpretations of line drawing data, domain-specific knowledge bases for interpretable visual structures, and gesture-based selection of visual objects. A system implementing these ideas, called Per-Sketch, begins to explore a new space of WYPIWYG (What Your Perceive Is What You Get) image editing tools.

title	Non-photorealistic rendering : A critical examination and proposed system
source	Middlesex University
summary	In the first part of the program the emergent field of Non-Photorealistic Rendering is explored from a cultural perspective. This is to establish a clear understanding of what Non-Photorealistic Rendering (NPR) ought to be in its mature form in order to provide goals and an overall infrastructure for future development. This thesis claims that unless we understand and clarify NPR's relationship with other media (photography, photorealistic computer graphics and traditional media) we will continue to manufacture "new solutions" to computer based imaging which are confused and naive in their goals. Such solutions will be rejected by the art and design community, generally condemned as novelties of little cultural worth ( i.e. they will not sell). This is achieved by critically reviewing published systems that are naively described as Non-photorealistic or "painterly" systems. Current practices and techniques are criticised in terms of their low ability to articulate meaning in images; solutions to this problem are given. A further argument claims that NPR, while being similar to traditional "natural media" techniques in certain aspects, is fundamentally different in other ways. This similarity has lead NPR to be sometimes proposed as "painting simulation" - something it can never be. Methods for avoiding this position are proposed. The similarities and differences to painting and drawing are presented and NPR's relationship to its other counterpart, Photorealistic Rendering (PR), is then delineated. It is shown that NPR is paradigmatically different to other forms of representation - i.e. it is not an "effect", but rather something basically different. The benefits of NPR in its mature form are discussed in the context of Architectural Representation and Design in general. This is done in conjunction with consultations with designers and architects. From this consultation a "wish-list" of capabilities is compiled by way of a requirements capture for a proposed system. A series of computer-based experiments resulting in the systems "Expressive Marks" and "Magic Painter" are carried out; these practical experiments add further understanding to the problems of NPR. The exploration concludes with a prototype system "Piranesi" which is submitted as a good overall solution to the problem of NPR. In support of this written thesis are : - * The Expressive Marks system * Magic Painter system * The Piranesi system (which includes the EPixel and Sketcher systems) * A large portfolio of images generated throughout the exploration

title	Knowledge Systems
source	Morgan Kaufmann Publishers Inc., San Francisco. p. 295
summary	Digital systems cannot act reliably and intelligently in ignorance. They need to know how to act intelligently. Computer systems that use knowledge are called knowledge-based systems, or simply, knowledge systems. Knowledge systems first came to the public's attention in the 1980s as a successful application of artificial intelligence. Since then their use has spread widely throughout industry, finance and science. But what are the principles behind knowledge systems? What are they useful for? How are they built? What are their limitations? How can they connect with human activities for creating and using knowledge? Addressing these questions is the purpose of this book. The art of building knowledge systems is inherently multidisciplinary, incorporating computer science theory, programming practice and psychology. The content of this book incorporates these varied fields covering topics ranging from the design of search algorithms and representations to techniques for acquiring the task specific knowledge required for developing successful systems. It discusses common representations for time, space, uncertainty, and vagueness. It also explains the knowledge-level organizations for the three most widespread knowledge-intensive tasks: classification, configuration, and diagnosis. In a university setting, this book is intended for use at the advanced undergraduate levels and beginning graduate levels. For students outside of computer science, this book provides an introduction that prepares them for using and creating knowledge systems in their own areas of specialization. For computer science students, this book provides a deeper treatment of knowledge systems than is possible in a general introduction to artificial intelligence.
