title	MAKING THE PROBLEM VISIBLE: PROJECT SPECIFIC INFORMATION IN COLLABORATIVE DESIGN
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 471-480
summary	This paper describes our current work in the development of an interactive, collaborative design space. It attempts to anticipate a future in which complex design Problems are undertaken by an interdisciplinary, collaborative group of contributors working within an electronic, networked environment. These networked working groups are made possible by the expanded use of high-speed digital networks and are expected to continue to grow within the design profession Using the design of an academic building as a case study, several new tools and techniques were used to develop an information place superimposed over the three-dimensional digital model of the site and proposed building. These tools allow the user to create a collection of data including site documentation and analysis; propose interventions; and access the data through three-dimensional icons in the modeL Several new techniques related to collecting and accessing information within the collaborative space are discussed.

title	Case-Based Structural Design - using weakly structured product and process information
source	Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary	Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

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

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

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

title	Knodes: Knowledge-Based Design Decision Support
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 357-374
summary	This paper describes the work in progress to develop a knowledge-based design support (KNODES) environment. The KNODES environment is intended to improve a designer's decision making potential, and to assist designers in a broad range of disciplines by making design knowledge and information more accessible. The framework exists as a multi-layered knowledge-based system reflecting both generic and domain specific aspects of the design activity and is designed to: enable the rapid dissemination of new design information, thus responding to shifts in design standards; take advantage of existing empirical design tools in unstructured areas of the design process; accommodate changes in user expectations and technological innovations at both the system and domain levels thus ensuring long term continuity and support,- offer multiple view points of the same design data by means of interchangeable interpreters. A prototype building design framework configured using the KNODES development tools is used to illustrate some of the salient features of the framework. Finally the paper will conclude with some insights into how such a design framework may be used as a knowledge acquisition tool in order to derive and formalise models of the design process.

title	ROP: An interactive spatial optimization and grouping computer application
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	As a part of a research project at Eindhoven University of Technology, the computer application ROP for space-planning problems was tested in practice. The use of the application in a real-world project was evaluated. The decision-making process for the development of alternatives for a courthouse was observed to see how the computer application could support decision-making. The aim of this paper is to describe the performance of ROP in a real-world setting. ROP appears to be a useful instrument in decision-making for space-planning problems. Especially in the early stages of the design process, it enhances insight among all participants in a project team. It can also be used in situations where little information is available. To conclude, ROP appears to enhance communi-cation between members of a design team.

doi	https://doi.org/10.52842/conf.acadia.1993.107
summary	Computer culture creates new demands on the process of making architecture. Both academia and practice are undergoing rapid changes due to the impact of information technology, and one of the most significant phenomena which has resulted from this transformation is collaborative design in a networked environment. Many researchers in the field have focused their efforts on minimizing or eliminating an apparent shortcoming of networked collaboration, namely the difficulty of immediate interaction between participants [Maher, Gero and Sand, 1993]. In an ongoing experiment in collaborative design we have taken a different approach. Instead of trying to work in a synchronous environment, we have taken the asynchronous nature of networked collaboration to be one of the important features of this ethereal medium, a feature whose consequences need to be explored.

title	Application of Endoscopy in Road–Design
source	Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 109-116
summary	Within the Dutch Ministry of Transport a special Division on Transport and Traffic Research is occupied with all aspects concerning mobility and traffic safety on a national level. Research and advice on the quality of the road–infrastructure is one of the main topics. For road–design a set of very detailed guidelines have been developed. Construction and reconstruction of parts of the high–way–network are tested against these guidelines. In this matter the actual road–user takes a central place. In the design–phase of a project on road-infrastructure contributions of a number of experts are taken into account. Expert–opinions on elements of the road–design result in a overall road–design. The road–scene of the overall–design is tested against visual requirements for safe driving, from a drivers point of view. Goal is to give advice on improvement of the visual quality of the road design. Research in this field is now carried out by Grontmij Consulting Engineers, mainly under authority of the Ministry of Transport. Key–word is Improvement of Quality. Who is going to notice? Who will benefit from it? Of course it is a comforting thought for road–owners and designers to know they won’t have to be ashamed for what they have come up with. Primary goal is that ‘We the people’ are provided with a high–standard road infrastructure. The road–scene research section studies the quality of the visual information as presented to the roadusers. We try to create visual circumstances in which drivers will be able to perform their driving task is a proper way. When the visual representation in the brain differs from reality, you have a serious problem. A traffic safety problem, with casualties and fatalities. A burden for society, financially and emotionally.

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

title	Understanding Shared Space for Informal Interaction among Geographically Distributed Teams
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 41-54.
summary	In a design project, much creative work is done in teams, thus requires spaces for collaborative works such as conference rooms, project rooms and chill-out areas. These spaces are designed to provide an atmosphere conducive to discussion and communication ranging from formal meetings to informal communication. According to Kraut et al (E.Kraut et al., 1990), informal communication is an important factor for the success of collaboration and is defined as ‚Äúconversations take place at the time, with the participants, and about the topics at hand. It often occurs spontaneously by chance and in face-to-face manner. As shown in many research, much of good and creative ideas originate from impromptu meeting rather than in a formal meeting (Grajewski, 1993, A.Isaacs et al., 1997). Therefore, the places for informal communication are taken into account in workplace design and scattered throughout the building in order to stimulate face-to-face interaction, especially serendipitous communication among different groups across disciplines such as engineering, technology, design and so forth. Nowadays, team members of a project are not confined to people working in one location but are spread widely with geographically distributed collaborations. Being separated by long physical distance, informal interaction by chance is impossible since people are not co-located. In order to maintain the benefit of informal interaction in collaborative works, research endeavor has developed a variety ways to shorten the physical distance and bring people together in one shared space. Technologies to support informal interaction at a distance include video-based technologies, virtual reality technologies, location-based technologies and ubiquitous technologies. These technologies facilitate people to stay aware of other‚Äôs availability in distributed environment and to socialize and interact in a multi-users virtual environment. Each type of applications supports informal interaction through the employed technology characteristics. One of the conditions for promoting frequent and impromptu face-to-face communication is being co-located in one space in which the spatial settings play as catalyst to increase the likelihood for frequent encounter. Therefore, this paper analyses the degree to which sense of shared space is supported by these technical approaches. This analysis helps to identify the trade-off features of each shared space technology and its current problems. A taxonomy of shared space is introduced based on three types of shared space technologies for supporting informal interaction. These types are named as shared physical environments, collaborative virtual environments and mixed reality environments and are ordered increasingly towards the reality of sense of shared space. Based on the problem learnt from other technical approaches and the nature of informal interaction, this paper proposes physical-virtual shared space for supporting intended and opportunistic informal interaction. The shared space will be created by augmenting a 3D collaborative virtual environment (CVE) with real world scene at the virtual world side; and blending the CVE scene to the physical settings at the real world side. Given this, the two spaces are merged into one global structure. With augmented view of the real world, geographically distributed co-workers who populate the 3D CVE are facilitated to encounter and interact with their real world counterparts in a meaningful and natural manner.

title	Practices of Distributed Intelligence and Designs for Education
source	Distributed Cognitions, edited by G. Salomon. New York, NY: CambridgeUniversity Press
summary	v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."

summary	The architectural working environment has changed during the last 30 years more than ever before. Most of the changes have been related with information and communication technologies (ICT). Architectural working methods and tools have changed profoundly, when CAD has replaced more traditional methods and tools. Communicative working environment and document management within design & construction has also been changed to digital, meaning email and project webs. Completing a traditional architectural profile of the 20th centrury, a drawer-designer, contemporary communicating and managing skills plus mastering ICT are needed today to operate modern architectural practise properly. The objective of this study is to create a change-oriented understanding of the contemporary architectural profession concentrating on architectural information management. The first phase, a literature study, will be followed by interviews and case-studies, to examine three hypothetically different periods of time: a) 1980-85 the era before CAD, the last days of hand-drawing, b) 1993-98 the era of digital drawing, the expansion of architectural CAD, c) 2000-05 the rise of integrated and pervasive web-supported digital design. The study will propose new aspects to be included in the modern architectural profile, namingly project coordination, collaborative team-work, design information integration and profound digital content management.

doi	https://doi.org/10.52842/conf.acadia.1998.008
summary	The last thirty years have seen the development of powerful new tools for architects and planners: CAD, 3D modeling, digital imaging, geographic information systems, and real time animated walkthroughs. That’s just the beginning. Based on our experience with CAD tools, analysis of design practice, and an understanding of computer hardware and software, we’re out to invent the next generation of tools. We think architects should be shakers and makers, not just consumers, of computer aided design. We started the Sundance Lab (for Computing in Design and Planning) in 1993 with a few people and machines. We’ve grown to more than a dozen people (mostly undergraduate students) and a diverse interdisciplinary array of projects. We’ve worked with architects and planners, anthropologists, civil engineers, geographers, computer scientists, and electrical engineers. Our work is about the built environment: its physical form and various information involved in making and inhabiting places. We cover a wide range of topics – from design information management to virtual space, from sketch recognition to design rationale capture, to communication between designer and computer. All start from the position that design is a knowledge based and information rich activity. Explicit representations of design information (knowledge, rationale, and rules) enables us to engage in more intelligent dialogues about design. The following describes some of our projects under various rubrics.

doi	https://doi.org/10.52842/conf.acadia.1993.173
summary	There is an essential contradiction between the making of buildings or built environments in a threedimensional modeler and the graphic control of this process. Three-dimensional modeling is a constructive activity, in which solids are assembled as they would be in an actual structure; it benefits the designer. Presentation and documentation, on the other hand, are prescriptive activities that direct some of the construction and all the visualization and criticism of the proposal; they benefit the user and builder. A building while being designed can be visualized and criticized from its solid model, and the model can take a variety of forms depending on its part): computer-based, drawn in orthographic or perspective projection, constructed of cardboard or wood, or described narratively by means of text, programmatic data, performance model or animation. However, practicing architecture is the process of recording and communicating the decision making process and the contractual obligations that result. In actual practice, in contrast to the designer directed ideal, more participants are brought in sooner at the beginning of a project and with more publicity, which in turn means keeping more, not fewer, records. As the profession evolves, records of the string of design decisions will become more automated, more carefully structured and more retrievable. More buildings will be "tracked" and exposed to review in this way because public environmental sensitivity will improve. The communication between a single designer and his own thoughts will become less and less important.

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

title	Architectural computer vision: Automated recognition of architectural drawings
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Computer vision offers the ability to transform digitized drawings into documents that can be used with computer systems. Recognition of digitized drawings can occur at the levels of (a) geometric elements, (b) building elements, and (c) spatial articulation. The last two levels apply not only to digitized images but also to computer-produced ones. The enormous burden placed on the user for inputting and manipulating CAD drawings suggests that automated recognition can add to the capabilities of CAD by making the computer more flexible with respect to inputting design information and more responsive to the actual concerns of the designer.

title	Recognizing Emergent Subshapes in Design Problem Solving: A Connectionist Investigation

summary	Human problem-solving behavior has been modelled as a search through the space as defined as problem states, within which earlier states move to subsequent ones by applying rules in the human mind until the goal state is found. This cognitive model of problem-solving has been broadly accepted and has become dominant in both cognitive psychology and artificial intelligence (AI). In the field of computeraided architectural design (CAAD), search models are also widely used for solving design problems, although various foci of design knowledge are differently represented by shape grammars, graphs, and knowledge-based systems using predicate logic for different purports. In design search, design evolves from one state to another by exhaustively or heuristically applying proper rules. Each rule application involves, first, pattern-matching the antecedent of a rule to the current state and, second, transforming the matched portion of that state into the consequence of the rule. However pattern-matching techniques of current CAAD systems are still limited. In current CAAD systems, only those two squares can be dealt with by patternmatching for further development. However, a human designer can effortlessly recognize not only those two but other emergent subshapes, for example a smaller square in the middle where the two squares overlap and two L-shapes in the corners. Therefore a human designer can thoroughly deliberate all these alternatives before making a decision. In other words, human designer is capable of restructuring shapes in terms of emergent subshapes in any step of designing.

summary	The basic point of our conception is not to submit the architect to technical means, but give him freedom of choice and the opportunity to work in the environment closest to the real one. In our situation it means, that we should provide work in real videoinformative space. Thus, our conception of education is to give all the junior students compulsory general information about videosimulation, and to ensure optional more professional work of undergraduates while carrying out their school projects. We consider, that in the architect’s activity simulation (making small-scale models) plays an essential part, because the small-scale model is the first and the only source of true three-dimensional information about the object designed. At the same time videosimulation does not deny or substitute computer-aided design. To get reliable visual information from the model is possible with the help of special technical means equipped with periscopic devices. In Moscow Institute of Architecture this work has been carried out for 10 years.

summary	UI innovations are often driven by a combination of technology advances and application demands. On the technology side, advances in interactive computer graphics hardware, coupled with low-cost mass storage, have created new possibilities for information retrieval systems in which UIs could play a more central role. On the application side, increasing masses of information confronting a business or an individual have created a demand for information management applications. In the 1980s, text-editing forced the shaping of the desktop metaphor and the now standard GUI paradigm. In the 1990s, it is likely that information access will be a primary force in shaping the successor to the desktop metapho. This article presents an experimental system, the Information Visualizer (see figure 1), which explores a UI paradigm that goes beyond the desktop metaphor to exploit the emerging generation of graphical personal computers and to support the emerging application demand to retrieve, store, manipulate, and understand large amounts of infromation. The basic problem is how to utilize advancing graphics technology to lower the cost of finding information and accessing it once found (the information's "cost structure"). We take four broad strategies: making the user's immediate workspace larger, enabling user interaction with multiple agents, increasing the real-time interaction rate between user and system, and using visual abstraction to shift information to the perceptual system to speed information assimilation and retrieval.
