summary	The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	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 Virtual Reality Design Environment with Intelligent Objects and Autonomous Agents
source	H.J.P. Timmermans (ed.), Design and Decision Support Systems in Architecture and Urban Planning Conference, Vol. 1: Architecture Proceedings, pp. 132-142
summary	New technological achievements and research results allow for the creation of innovative design tools for architects, that do not originate from paper-based paradigms but instead make optimised use of the present technology and programming concepts. The core of our system is comprised of an intuitive interactive modelling tool. It runs in a virtual reality set-up, where the user can use 3D glasses to experience rooms and 3D input devices to model in three dimensions. The interface is free from widget-like buttons or menus, so that the user is undisturbed when moving into the virtual world of the design. The system can also run in a distributed fashion, so that a number of users can look at and modify the same design. The 3D model can be generated in a sketch-like fashion using solids and voids, void modelling turns out to be very valuable for architectural design. The objects in this system can contain forms of intelligence to produce such behaviour as: falling because of gravity, collision avoidance, and autonomous motion. Interactive behaviour can also be assigned to the objects. Autonomous Agents are added to the system to enhance the designer support. These are agents that enhance the virtual environment, agents that take over tasks, and agents that help to test the design. The system shows new interface and interaction approaches that support the architectural design process intelligently.

title	A World of Data: An Animated Construction Information System as a Virtual Hypergraphic Environment
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 267-274
doi	https://doi.org/10.52842/conf.acadia.1996.267
summary	This paper describes research on an animated construction information system organized as a hypergraphic virtual environment. The user enters this environment to interact with the information it contains. A matrix of cubes sits as the gateway to an array of data chambers that give this information its virtual form. A mouse click on one of these cubes leads to a three-dimensional interface that is a simulation of the object to be constructed. Reflective-transparent panels surround the simulation and display two-dimensional projections of its pieces. These panels capture projections of slices through the pieces of the object represented by the simulation. Below the zero plane are slices of floor framing, foundation, excavation, utilities, and soil conditions. Above are ceilings, framing, and roofing. To the sides are finishes, wall framing, fixtures, and elevations. This immersive virtual environment extends as an array of data chambers partitioned by the suspended reflective-transparent panels. Pathways around these partitions lead to secondary chambers that contain sub-simulations of the plumbing, electrical, and HVAC systems. Design-team members access these chambers to coordinate the document's development, review progress, and make changes to the information system. The result is a WORLD of data where graphic information defines both space and time. This breaks with the notion of a construction document as an object-of-exchange and suggests a new focus for the use of computers in the design and construction process.

source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 85-97
doi	https://doi.org/10.52842/conf.acadia.1996.085
summary	The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, schematic design phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to benefit from the capabilities of multiple tools. The BDA provides a graphical user interface that consists of two main elements: the Building Browser and the Decision Desktop. The Browser allows building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to any number of parameters addressed by the tools linked to the BDA. The BDA is implemented as a Windows-based application for personal computers. Its initial version is linked to a Schematic Graphic Editor (SGE), which allows designers to quickly and easily specify the geometric characteristics of building components and systems. For every object created in the SGE, the BDA supplies “smart” default values from a Prototypical Values Database (PVD) for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE and the PVD, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia Case Studies Database (CSD). The next version of the BDA will be linked to additional tools, such as a photo-accurate rendering program and a cost analysis program. Future versions will address the whole building life-cycle and will be linked to construction, commissioning and building monitoring tools.

title	Some Phenomena of Spatial Characteristics of Cyberspace

summary	"Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

title	MEDIA MATTERS: NUDGING DIGITAL MEDIA INTO A MANUAL DESIGN PROCESS (AND VICE VERSA)
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 31-43
doi	https://doi.org/10.52842/conf.acadia.1996.031
summary	This paper reports on a media class offered during the 1995-96 academic year at the University of Oregon. This course, a renovation of an existing 'manual' media offering targeted intermediate Ievel graduate and undergraduate students who, while relatively experienced design students, were relatively inexperienced users of digital media for design. This course maintained a pedagogical emphasis on design process, a point of view that media are powerful influences on design thinking, and an attitude toward experimentation (and reflection) in matters of media and design process. Among the experiments explored were fitting together digital with manual media, and using digital media to collaborate in an electronic workspace. The experience offers opportunity to consider how digital media might be more widely integrated with what remains a predominantly 'manual' design process and media context for many architecture schools and practices.

title	Bi-directional Inference in Thermal Design
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 133-143
doi	https://doi.org/10.52842/conf.acadia.1996.133
summary	This paper demonstrates a computational bi-directional energy modeling approach for building design development. Conventional simulation tools may be labeled as mono-directional in that they require a more or Iess complete design definition in order to derive performance indicators. However, in certain circumstances, it may be desirable to reverse this process: a bi-directional (or "open") inference mechanism would allow for the identification of those changes in the design variables that would accommodate a desired change in a performance indicator. The performance-to-design mapping process is an ambiguous one: the same performance (e.g. energy use of a building, temperature variations in a space) may be achieved by different design configurations (various wall and window dimensions/properties, building orientation/massing, etc.). As a result, the actual implementation of a bi-directional inference tool is a rather difficult task. The development described in this paper utilizes a preference-based approach that involves the formalization of various external or internal constraints and preferences (such as code and standard requirements, results of post-occupancy studies, individual priorities of designers and their clients, etc.) in terms of normalized numeric scales. After a brief review of the underlying technology for the implementation of the inference engine, the paper demonstrates an actual design session using a bi-directional thermal simulation tool. Specifically, a use-scenario is described in which the designer explores the tradeoffs between various design variables (glazing area, glazing type, and floor mass) in view of the resulting energy performance of a typical residential building. The paper concludes with a discussion of the potential and limitations of the bi-directional approach toward active convergence support for performance-oriented design development.

title	Generic Representations and the Generic Grid: Knowledge Interface, Organisation and Support of the (early) Design Process
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Computer Aided Design requires the implementation of architectural issues in order to support the architectural design process. These issues consist of elements, knowledge structures, and design processes that are typical for architectural design. The paper introduces two concepts that aim to define and model some of such architectural issues: building types and design processes. The first concept, the Generic grid, will be shown to structure the description of designs, provide a form-based hierarchical decomposition of design elements, and to provide conditions to accommodate concurrent design processes. The second concept, the Generic representation, models generic and typological knowledge of building types through the use of graphic representations with specific knowledge contents. The paper discusses both concepts and will show the potential of implementing Generic representations on the basis of the Generic grid in CAAD systems.

title	Automatic generation of the controlling-system for a wall construction robot
source	Automation in Construction 5 (1) (1996) pp. 15-21
summary	In this article we present several important aspects of a software system control. This is designed and developed for a wall assembly robot in an European Esprit III project called ROCCO, RObot assembly system for Computer integrated COnstruction. The system consists of an off-line program for planning of complex assembly tasks and for generating robot actions. The execution is controlled through an adaptive user interface and gives the user the possibilities to switch in an on-line mode command. All the software is designed with the object-oriented concept and implemented in C + +. The wall assembly system is organized on the base of the successive generation of different types of actions, called "Mission", "Task", and "Action". They represent different levels of assembly complexities. Those different actions are organized in a tree structure. Furthermore, the software system can be connected to a CAD-robot simulation software for checking the robot assembly motions. Added to the control system, a recovery module has been implemented for all possible errors during the construction. First the OO-model of the world and of robot activities will be presented. Secondly, several aspects of the algorithm will be explained and at the end we will show the strategy used for the robot motion.

title	Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

title	The Right Tool at the Right Time - Drawing as an Interface to Knowledge Based Design Aids
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 191-199

summary	Designers use different symbols and diagrams in their drawings to explore alternatives and to communicate with each other. Therefore, a useful design environment should attempt to infer the designer's intentions from the drawing and, based on this inference, suggest appropriate computational tools for the task at hand. For example, a layout bubble diagram might activate design cases with similar configurations. Scribbles of view lines on a floor plan might bring up a spatial analysis tool. This research aims to develop an integrated digital sketching environment to support early design activities. The paper proposes RT, an intelligent sketch environment that provides the designers with the right tools at the right time.

title	A Virtual Reality Design Environment with Intelligent Objects and Autonomous Agents
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	New technological achievements and research results allow for the creation of innovative design tools for architects, that do not originate from paper-based paradigms but instead make optimised use of the present technology and programming concepts. The core of our system is comprised of an intuitive interactive modelling tool. It runs in a virtual reality set-up, where the user can use 3D glasses to expe-rience rooms and 31) input devices to model in three dimensions. The interface is free from widget-like buttons or menus, so that the user is undisturbed when moving into the virtual world of the design. The system can also run in a distributed fashion, so that a number of users can look at and modify the same design. The 31) model can be generated in a sketch-like fashion using solids and voids, void modelling turns out to be very valuable for architectural design. The objects in this system can contain forms of intelligence to produce such behaviour as: falling because of gravity, collision avoidance, and autonomous motion. Interactive behaviour can also be assigned to the objects. Autonomous Agents are added to the system to enhance the designer support. These are agents that enhance the virtual environment, agents that take over tasks, and agents that help to test the design. The system shows new interface and interaction approaches that support the architectural design process intelligently.

title	LOST IN SPACE? ARCHITECTURAL PSYCHOLOGY - PAST, PRESENT, FUTURE
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	A methodological review by Kaminski (1995) summed up five perspectives in environmental psychology - patterns of spatial distribution, everyday “jigsaw puzzles”, functional everyday action systems, sociocultural change and evolution of competence. Architectural psychology (named so at the Strathclyde conference 1969; Canter, 1973) as psychology of built environments is one leg of environmental psychology, the second one being psychology of environmental protection. Architectural psychology has come of age and passed its 25th birthday. Thus, a triangulation of its position, especially in Central Europe, seems interesting and necessary. A recent survey mainly on university projects in German-speaking countries (Kruse & Trimpin, 1995) found a marked decrease of studies in psychology of built environments. 1994, 25% of all projects were reported in this category, which in 1975 had made up 40% (Kruse, 1975). Guenther, in an unpublished survey of BDP (association of professional German psychologists) members, encountered only a handful active in architectural psychology - mostly part-time, not full-time. 1996, Austria has two full-time university specialists. The discrepancy between the general interest displayed by planners and a still low institutionalization is noticeable. How is the research situation? Using several standard research data banks, the author collected articles and book(chapter)s on architectural psychology in German- and English-language countries from 1990 to 1996. Studies on main architecture-psychology interface problems such as user needs, housing quality evaluations, participatory planning and spatial simulation / virtual reality did not outline an “old, settled” discipline, but rather the sketchy, random surface of a field “always starting anew”. E.g., discussions at the 1995 EAEA-Conference showed that several architectural simulation studies since 1973 caused no major impact on planner's opinions (Keul&Martens, 1996). “Re-inventions of the wheel” are caused by a lack of meetings (except this one!) and of interdisciplinary infrastructure in German-language countries (contrary to Sweden or the United States). Social pressures building up on architecture nowadays by inter-European competition, budget cuts and citizen activities for informed consent in most urban projects are a new challenge for planners to cooperate efficiently with social scientists. At Salzburg, the author currently manages the Corporate Design-process for the Chamber of Architecture, Division for Upper Austria and Salzburg. A “working group for architectural psychology” (Keul-Martens-Maderthaner) has been active since 1994.

title	PHIDIAS II - In Support of Collaborative Design
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 147-154
doi	https://doi.org/10.52842/conf.acadia.1996.147
summary	The World Wide Web in combination with Java and Virtual Reality Modeling Language (VRML) create great opportunities for collaboration by distributed design teams. To take advantage of these opportunities, we have begun to create a version of the PHIDIAS hyperCAD system (McCall, Bennett and Johnson 1994) that will support communication and collaboration among designers over the Word Wide Web. PHIDIAS is an intelligent, hypermedia-based system for computer-aided design. Our strategy is to divide PHIDIAS into two parts: 1) a client-side user interface and 2) a server-side hyperCAD database engine. The client-side interface is being implemented using Java and VRML. Implementing the PHIDIAS front-end with Java enables program code distribution via the World Wide Web. VRML provides PHIDIAS with client-side computation and display of 3D graphics.

title	The Development of a Virtual Studio Environment to Support Collaborative Building Design
source	Design, Synergy, Collaboration - selected papers from DEcon Conference
summary	This paper describes the development of a virtual studio environment to support collaborative working in the domain of building design. By applying and extending the real-world design studio model within the Internet-based distributed computing environments, the virtual studio concept has been refined as computerised settings, which integrate both the dispersed human designers and the distributed CAD applications. The hope is to achieve the similar effect as physical co-presence while providing extra advantages such as the support for automatic communication archiving and being less obtrusive than sharing a physical office. Like its real-world counterpart (which usually consists of the office, desks, file cabinets, instruments etc), such a virtual studio consists of the several major components, including a multi-user graphical user interface displaying the shared virtual workspace on each designer's workstation, distributed multimedia databases and CAD tools for processing the domain tasks, and rich human-human interaction facilities supporting a variety of communication modes. Advance distributed object computing technologies (0MG CORBA in particular) have been adopted for modelling and implementing the distributed systems, W3 (world-wide-web) technologies have also been exploited for constructing the distributed multi-media databases and an image communication kit. In contrast to the traditional CAD integration which is usually focused solely on the well-structured technical part of the product and process, the described research advocates a human-centred systems development strategy in which design is first of all taken as a process of social construction.

title	Working in a Virtual World: Interaction Techniques Used in the Chapel Hill Immersive Modeling Program
source	Research report TR96-029, Department of Computer Science, University of North Carolina, Chapel Hill
summary	This paper presents a description of the interaction techniques used in the Chapel Hill Immersive Modeling Program (CHIMP). CHIMP is intended for the preliminary stages of architectural design. It is an immersive system; users work directly within a virtual world. The main goal has been to develop interaction techniques that exploit the benefits of working immersed while compensating for its limitations. Interaction techniques described and discussed in this paper include: . Action at a distance . Look-at menus . Remote controls (hand-held widgets) . Constrained object manipulation using twohands . Two-handed control panel interaction . Worlds in miniature .

title	Designing Visual Interfaces: How to Create Communication -- Oriented Solutions Tutorial 3
source	Proceedings of ACM CHI 96 Conference on Human Factors in Computing Systems 1996 v.2 pp. 332-333
summary	This tutorial describes a number of fundamental techniques applied routinely in communication-oriented visual design. The orientation, process, training, and culture of the visual design disciplines (graphic design, industrial design, interior design, architecture) are essential components of effective interface design. Unfortunately, few software developers or human factors engineers receive any training in these disciplines. This tutorial describes important design rules and techniques internalized by every visual designer through coursework and studio experience. While mastery will indeed require extended practice, the techniques we describe are not difficult to understand and can be immediately applied to real-world problems. We draw our background, training, and influence from the rational, functional, information-oriented perspective of the Modernist design ethic. Because all graphical user interfaces are communication systems, we believe their design should reflect these same values. Our tutorial is organized not along the traditional subdisciplines of color, typography, or ideation, but along the problems of graphical interface design as experienced in commercial software development. We describe basic design principles (the what and why), common errors, and practical techniques (the how) for each of the six major areas outlined below.
