title Playing with Time - Continuous Temporal Mapping Strategies for Interactive Environments
source 6th Canadian GIS Conference, (Ottawa Natura Resources Canada), pp. 318-329
summary The growing acceptance of GIS technology has had far- reaching effects on many fields of research. The recent developments in the area of dynamic and temporal GIS open new possibilities within the realm of historical research where temporal relationship analysis is as important as spatial relationship analysis. While topological structures have had wide use in spatial GIS and have been the subject of most temporal GIS endeavours, the different demands of many of these temporally- oriented analytic processes questions the choice of the topological direction. In the fall of 1992 the Montreal Research Group (MRG) of the Canadian Centre for Architecture mounted an exhibition dealing with the development of the built environment in 18th- century Montreal. To aid in presenting the interpretive messages of their data, the MRG worked with the Centre for Landscape Research (CLR) to incorporate the interactive capabilities of the CLR's PolyTRIM research software with the MRG's data base to produce a research tool as well as a public- access interactive display. The interactive capabilities stemming from a real- time object- oriented structure provided an excellent environment for both researchers and the public to investigate the nature of temporal changes in such aspects as landuse, ethnicity, and fortifications of the 18th century city. This paper describes the need for interactive real- time GIS in such temporal analysis projects and the underlying need for object- oriented vs. topologically structured data access strategies to support them.

title Implementing an Integrated Environment for Urban Simulation CAD, Visualization and GIS
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Using technology which has been adapted from military flight simulation hardware and software, researchers at UCLA's Graduate School of Architecture and Urban Planning are currently developing an integrated computing environment for Urban Simulation which includes a high-level visual simulation package, an industry standard CAD system, and a traditional two dimensional geographic information system and data bases. The focal point of the integrated system is a visual simulation engine which has been developed using Silicon Graphics' IRIS Performer application development environment. With this system, aerial photographs can be combined with street level video to efficiently create a realistic (down to plants, street signs and the graffiti on the walls) model of an urban neighbourhood which can then be used for interactive fly and walk-through demonstrations. Links have been established between this visual simulation system and AutoCAD to allow models (at varying levels of detail) to be generated using the CAD system and translated into the form required for the visualization system. Links between the GIS system (in this case ARC/INFO and ARCVIEW) and the visual simulation system provide the capability for dynamic query and display of information from the GIS data base in a real-time 3-dimensional format. Links between the CAD and GIS systems allow common base maps to be used for the GIS and modelling systems as well as automatic generation of 3-d form. While an earlier paper by the authors discussed proposed strategies for such an Urban Simulation System, this paper focuses on the results of actual implementation of these strategies, as well as the use of the system for modelling, exploration and display of alternative physical environments.

title Maximising the Benefits of CAD Systems in Architectural Education
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 228

summary The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.

summary Computer-aided-design (CAD) systems are now used to design all kinds of artifacts, from jet fighters to works of art. A major challenge in the design of a CAD system itself is the user interface (UI). Developing the UI to a CAD system raises myriad questions about input devices and techniques, display devices and techniques, and the details of the dialogue that relates the two. But these questions are ancillary to one central question: what is the fundamental nature of the interaction between human and computer in the design process supported by the CAD system? Is the design activity essentially manual, with the computer playing the role of passive tool, like a pen or paintbrush? Or is the computer augmenting the human designer by actively restricting available design choices, or by playing the role of critic or "improver"? Or maybe the interaction paradigm is one of "interactive evolution," in which the computer is responsible for generating design alternatives, with the human merely choosing among choices suggested by the machine. Or perhaps the computer performs the design process completely automatically, with a final acceptance check being the only human contribution? The panelists will describe these different paradigms for human-computer cooperation in a set of related CAD systems and prototypes and discuss the conditions under which each paradigm might be most useful.

title DesignSpace: A Manual Interaction Environment for Computer Aided Design DEMONSTRATIONS: Virtual Reality Multimedia
source Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 33-34
summary DesignSpace is a computer-aided-design (CAD) system that facilitates dexterous manipulation of mechanical design representations. The system consists of an interactive simulation programmed with a seamless extended model of the designer's physical environment and driven with continuous instrumentation of the designer's physical actions. The simulation displays consistent visual and aural images of the virtual environment without occluding the designer's sensation of the physical surroundings. Developed at Stanford University's Center for Design Research (CDR), DesignSpace serves as an experimental testbed for design theory and methodology research. DesignSpace includes significant contributions from recent CDR development projects: TalkingGlove, CutPlane, VirtualHand, TeleSign, and VirtualGrasp. The current DesignSpace prototype provides modeling facility for only crude conceptual design and assembly, but can network multiple systems to share a common virtual space and arbitrate the collaborative interaction. The DesignSpace prototype employs three head-tracked rear projection images, head-coupled binaural audio, hand instrumentation, and electromagnetic position tracking.

summary A design problem shared over the Internet raises issues of how digital media and group dynamics affect networked design collaborations. This paper describes how to conduct a long-distance studio and compares asynchronous and synchronous collaborative techniques. Digital methods are discussed in relationship to both the creative process and design communication. In schematic stages, less precise tools used asynchronously allow free exploration and creative misreadings, while in later stages, more direct real-time exchanges bring a project to resolution. For the final review, synchronous video-conferencing with interactive graphics allow comparison of cross-cultural differences. Used effectively, these tools can electronically create a compelling sense of place. Ways to foster a strong virtual community are discussed in an agenda for future virtual design.

title User Interfaces and Systems for Remote Design Working on ISDN Systems
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper will discuss the requirements and possible configurations of user interfaces suitable for remote working multi-disciplinary design practices. Telecom companies throughout Europe are making heavy investments in digital communication technology (ISDN). The networks being created will form a standard method of high speed data transfer which can be readily accessed by any computer hardware platform. There are great opportunities for remote working by design groups, not simply sharing data but also interactive working and video communications. Digital communications provide the electronic arterial system to the new field of remote computing,whilst cheap and effective hardware and software support systems provide readily usable platforms on which to build remote multi-disciplinary design practices where the exploitation of specialistknowledge and skills is not limited by traditional methods of communication. ISDN networks allow real time video, voice and design software interaction - indeed, everything except the designer's physical presence. However as with all computer technology and indeed communications technology the user interface which gives access and control is vitally important. The user interface should provide the following features: be transparent to the user and simple and reliable to operate; allow an interactive window/s into the remote site's design information whatever the type of application being dealt with; carry out data compression, file transfer and file management procedures with minimum input from the user; cause no conflicts with design software or secondary applications;be able to access different platforms.

title Matchmaker: An Instrument for Matching Demand for and Supply of Buildings and Revealing Specific Discrepancies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary To match supply and demand of buildings, various approaches are possible. While artificial intelligenceis favoured by some, we think that a less 'heavy' approach can be more cost and time efficient. The casewe have chosen to exemplify our approach concerns architectural heritage. To match supply and demandwhile at the same time respecting the constraints imposed by cultural heritage, it is necessary to bringthem together and to effectuate feasibility studies in the shortest possible time. The feasibility study shouldbe served by tools allowing the various partners to communicate on the level of the match between them, translated in terms of spatial organisation and building constraints. In the past years, our designmorphology group has developed and tested a graphic-based reordering tool which has been applied to large governmental buildings, both existing and new. The same tool can be used for weighted objectives ranking and evaluation, to have a synthetic view of the combined basic preferences and differences of the involved parties as for example in a jury wise evaluation and ranking of alternative proposals. The proposed tool is the electronic and graphic version of the data and association matrices, which have been for a long time recommended for use in the preliminary phases of design. But as long as these instruments could only be drawn and redrawn on paper they were much too ineffectual and found little real application. The developed tool is connected by sub-routines to a computer aided design package, within which the spatial patterns are translated into plans and attached data bases. The matching takes place in a number of steps. The first is to describe the organisation (the demanding party) as functional units which can be made corresponding with spatial units. The prescription of spatial needs can take place in both quantitative and qualitative manners. The Matchmaker tools offer the possibility of interactive clustering of spatial needs. Another step, which can be taken concurrently, is to describe the monument in spatial units and distance relationships. The input can be generated directly within the matrix, but it is much easier, more self evident and realistic to generate this automatically from the draughted plan. The following step is the input of constraints originating from heritage preservation objectives, expressed in levels of authorised intervention. Again, the Matchmaker tools offer here the possibility of visual clustering of spatial units, their relationships and associated properties. In the next step, the matching takes place. In this step the actual positions, properties and constraints of existing spaces in the monument are compared (and visualised by discrepancies views) to the optimised and clustered spatial needs of the end user. In the following phase, the feasibility in terms of space, building fabric and costs can be appraised. Once a compromise has been attained, preliminary proposals can be designed and laid down in terms of drawings. The spatialdesigns can then again be translated into matrix views and evaluated.

summary For a long time the Architecture-Engineering-Construction (AEC) community has had difficulty in communicating the content of their work, not only the various specialties involved, but also to their clients. Studies (Doorst and Cross 2001; Bakhtin 1994) suggest the importance of multi-role collaborative environments in supporting design processes. We are developing a Multi Level Design Review Tool for the AEC industry which allows multiple actors to congregate and interact as agents around a central Building Model. It merges real-time virtual 3D visualization technologies with Industry Foundation Classes (IFC) to support both high levels of semantic content and seamless interoperability.

summary Augmented Reality (AR) technologies are often perceived as the most impactful method to enhance the communication between the designer and the client during the iterative design process. However, the significance of designing the User Interface (UI) and the User Experience (UX) are often underestimated. To intercede, this research aims to employ new and existing techniques to develop UI's, and comparatively assess "the accuracy and completeness with which specified users can achieve specified goals in particular environments" (Stone, 2005) - a notion this research delineates as 'effectiveness'. Prompted by the work of key scholars, the developed UI's were assessed through the lens of existing UI evaluation techniques, including: Usability Heuristics (Nielsen, 1994) and Visual and Cognitive Heuristics (Zuk and Carpendale, 2006). In partnership with PTW Architects, characteristics such as the rapidity and complexity of interactions, in conjunction with the interface's simplicity and intuitiveness, were extracted from 15 trials underwent by architectural practitioners. The outcomes of this research highlights strategies for the effective development of user interface design for mobile augmented reality applications.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

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.

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 Data representations in an integrated architectural design environment
source University of Strathclyde, Dept. of Architecture and Building Science
summary The architectural design process is very complex and involves cross-disciplinary communication among many related fields. Given the further problems arising from the technological advances in building materials and construction methods, an integrated design environment becomes a central design issue. There have been many attempts to analyse and structure the design process as a uniform hierarchical framework. Most of the attempts resulted in a vague and inappropriate outcome due to the lack of understanding of architectural design complexity and inconsistent design data control sequence. A design problem cannot be comprehensively stated because the design problem has a multi-disciplinary nature and the design problem itself evolves as solutions are attempted by the designer. Therefore, an ideal CAAD system should have the capability to accommodate the multi-disciplinary nature of design and should not prescribe or restrict design concepts and design knowledge. A well designed integrated design environment provides more information and invokes creative imagination for each design stage, and therefore creative decision making by the designer can be achieved. This thesis proposes a prototype architectural design environment, Hybrid Integrated Design Environment [HIDE], which aims to integrate all applications for designing a building. Within the object-oriented design environment, a unified data model and a data management system have been implemented to seamlessly connect all applications. Development of the environment needs to consider the fundamental interaction between each module. Devising a data structure that is appropriate to an effective data communication among the various design stages is essential in a totally integrated CAAD system. The suggested unified data model organizes the structure of the design data to keep the design consistent throughout the design and construction process. By means of the unified data model, integrated CAAD systems could represent and exchange design information at a semantic level, i.e. the user’s way of thinking, such as exchanging components and features of a building rather than graphical primitives. In consequence, the unified data model reduces the misunderstandings and communication problems among the multiple disciplines of architectural design. The suggested data management system supports the consistent and straight forward mechanisms for controlling the data representation through the inter-connected modules. It is responsible for creating, maintaining, and viewing a consistent database of the design description. It also helps to perform effective data communication among the various design stages to ensure quality and time saving in the final construction of the building. To support inter-disciplinary communication of design concepts and decisions, the integrating of relevant CAAD tools is essential. In the environment, the integration of CAAD tools has been performed on the basis of how well computerized design tools can assist designers to develop better solutions, enabling them to manipulate and appraise varying solutions quickly and with a minimum of effort in an environment conducive to creative design. A well designed user interface system can also benefit the seamless working environment. The proposed user friendly interface system allows a user to explore the environment in a highly interactive manner. From the development of the early data model to the final design, a user could benefit from the prototypes and methods of the user interface system. The ultimate goal of the prototype environment is to suggest a future design environment which helps the architect to have minimum discontinuity in his creativity and make the design process similar to the natural design process with the help of a set of design assistance modules. A prototype version of HIDE has been implemented and a demonstration of the environment is part of this thesis.

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 Development of an Expert Cad System for Visual Design of a Bridge in a Landscape
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Architects, landscape architects and urban designers are often required to be involved in the process of bridge design from an aesthetic point of view. The authors have been developing a comprehensive CAD system to support such visual design works, especially at an early stage of design. Conventional complicated technical standards and guidelines tend to discourage creative design. In order to support free conception and creation of bridge forms, this system includes a visual design core system as a workshop, even enabling freehand sketch drawing on existing landscape images of the site. This is supported by a landscape simulation subsystem. The system can also provide initial design ideas with several different types of bridge form, derived from knowledge based subsystems on design guidelines and precedent examples which can be quoted also to examine the physical possibility of sketch drawn alternatives in terms of structural dimensions and construction costs. Created design alternatives will be analyzed by a visual impact analysis subsystem to assess their influences on surrounding environments from a visual geometri-cal standpoint. This system is intended to enable architects, landscape architects or urban designers to create and examine design alternatives on a real-time basis.

title Placeholder: Landscape and Narrative In Virtual Environments
source ACM Computer Graphics Quarterly Volume 28 Number 2 May
summary The idea of using virtual reality for entertainment purposes is actually quite recent in the history of VR technology. Early VR entertainment applications, appearing in the late 1980s, were extensions of the existing "serious" application of flight simulation training. The other branch of flight - simulator technology - motion platforms used in synchronization with motion video or animation - was much more amenable to the theme park environment. These systems, of which Star Tours is the best known, trade off individual viewpoint control and the sense of agency for thrilling, finely calibrated effects and the optimization of "throughput" - that is, getting the most people through the ride in the least time. Second to motion-platform rides in this regard are networked pods, as used in Virtual World Entertainment systems (previously Battletech). "Classic" virtual reality, with head-mounted displays and various forms of body tracking, are especially problematic in theme park environments for several reasons. It takes time to get the gear onto the participants. Only a handful of people can experience the attraction simultaneously (although a much larger audience might watch what the people "inside" the VR are doing). A hard-driving plot with distinct beginning, middle, and end is a great way to control how long an experience takes, but "classic" VR is inimical to this kind of authorial control - it works best when people can move about and do things in virtual environments in a relatively unconstrained way.

title Shape deposition manufacturing
source Vienna University of Technology
summary This thesis addresses the issue of rapidly and automatically fabricating functional metal parts directly from CAD models. A newly developed process called Shape Deposition Manufacturing (SDM) is introduced. The process is based on the concept of layered manufacturing in SFF, but uses separate deposition and shaping steps to create a layer. Three dimensionally shaped layers are created using 5-axis CNC machining, to achieve the required geometric accuracy for fully functional shapes. Thermal deposition technologies (thermal spraying, welding) are used to achieve the required material properties. A novel, droplet based deposition process, microcasting, has been developed, to create well- bonded, high-strength material, while minimising the heat input into previously shaped layers. To create layers with a true three dimensional geometry, more detailed building strategies, than used by conventional SFF processes, are required by the SDM process. A CAD based planning system, which addresses these issues by decomposing a solid model of a part into layers and manufacturable, fully three dimensional segments is described. An automated testbed facility installed at Carnegie Mellon's Shape Deposition Laboratory is discussed, and shows the feasibility of automating the process. The microcasting process is explained in detail and its performance in the SDM environment is evaluated. Different strategies and material combinations for the support structure have been developed and are presented with detailed descriptions of several building strategies for parts with various complexity and material quality. Material properties of structures created by the SDM process are evaluated. Problems affecting the accuracy and material integrity of SDM created structures, which mainly involve the buildup of thermal stresses during material deposition, are identified and opened for future research. Finally, various parts, with different complexity, have been built with the SDM process, to show the feasibility and performance of the process. Building time and material usage are evaluated and compared to conventional SFF processes

title Boundaries, Interdependence, and Coordination in ConstructionNetwork Organizations
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Of the profileration of new business paradigms in recent years, one of the primary foci has been building closer relationships between firms in the value adding chain. Lean production, which encompasses J1T, supply-chain management, and TQM/continuous improvement, has provided an important paradigm for reorganization of business practices and is in the process of revolutioni-zing western mass production industries, particularly the automotive industry. While lean production is attractive, it is not appropriate for all industries or production requirements. Lean production works best within a relatively stable production volume and stable range of products. "Mass customization" has proven difficult for accomplished lean producers such as Toyota, and requires a different set of organizational disciplines than those used in lean production. For example, in the lean production paradigm, relationships with suppliers are long-standing and steady, while in a mass customization paradigm, relationships with and between long-term suppliers will vary over time, and new suppliers will enter and leave the organization in a transient fashion. The organization form appropriate to mass customization is the network organization (also known as the virtual corporation in the popular business press), of which construction project organization is an instance, At the project level, we examine construction organization in the context of network organization theory. In particular, we examine boundaries between firms to highlight problems of coordination in a multi-firm environment, and the interdependencies that arise due to coordination needs. We provide a conceptual framework to describe these aspects of construction network organization, and discuss ways that different construction firms are dealing with coordination and boundary problems by rethinking contractual relationships and building closer ties with other firms in the network.

title Cultural formations in text-based virtual realities
source University of Melbourne
summary Beginning with an understanding of virtual reality as an imaginative experience and thus a cultural construct rather than a technical construction, this thesis discusses cultural and social issues raised by interaction on 'MUDs', which are text-based virtual reality systems run on the international computer network known as the Internet. MUD usage forces users to deconstruct many of the cultural tools and understandings that form the basis of more conventional systems of interaction. Unable to rely on physical cues as a channel of meaning, users of MUDs have developed ways of substituting for or by-passing them, resulting in novel methods of textualising the non- verbal. The nature of the body and sexuality are problematised in these virtual environments, since the physical is never fixed and gender is a self-selected attribute. In coming to terms with these aspects of virtual interaction, new systems of significance have been developed by users, along with methods of enforcing that cultural hegemony through power structures dependent upon manipulation of the virtual environment. These new systems of meaning and social control define those who use MUDs as constituting a distinct cultural group.
