title	A Web Environment to Support User Participation in the Development of Apartment Buildings
source	Special Focus Symposium on WWW as the Framework for Collaboration, InterSymp 2000, July 31-August 5, Baden-Baden, Germany, pp. 225-231
summary	In Taiwan, apartments are sold before ever been built. Apartment buyers can customize their units until the construction takes place. This customization process has become a very unique form of user participation in the development of apartment buildings in Taiwan. However, in all customizations, large amount of information has to be documented and exchanged between related agencies for each apartment unit. For an apartment building that contains over 40 units, managing the information can be a daunting task. We are developing a web environment to support the customization process and enable efficient management and timely exchanges of information. The environment provides three levels of design interaction to encourage user participation in a controlled customization process. This paper describes the framework of this web environment, illustrates its functionality through a running prototype, and discusses technical issues encountered during its implementation.

title	Supporting collaborative design groups as design communities
source	Design Studies, Vol. 21, no. 2, March
summary	This paper explores computer support for unstructured collaboration. A web-based online environment used in conjunction with a graduate-level architectural studio was investigated, with special attention given to patterns of online behavior and the perceptions of those who used the environment. It was assumed that asynchronous collaborative environments like the one studied naturally alleviate certain problems like evaluation apprehension and production-blocking, but do not on their own motivate contributions to a group in an unstructured setting. It was hypothesized that open participation hinges on the development of a sense of community, which itself depends partially on environmental factors intrinsic to the support environment. The environment studied failed to promote open interaction and did not appear to sustain a strong sense of community. Environmental factors thought to have played a role include page structuring, page-naming conventions, and the spatial clustering of textbased exchanges.

summary	It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
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.

title	An industry foundation classes Web-based collaborative construction computer environment: WISPER
source	Automation in Construction 10 (1) (2000) pp. 79-99
summary	Collaborative working in construction is becoming a reality as many activities are performed globally with actors based in various geographical locations. This paper discusses the development and implementation of a collaborative working environment for construction at the University of Salford which is known as Web-based IFC Shared Project EnviRonment (WISPER). The environment is based on a three tier architecture, where user interfaces, business logic and database are kept separate. A Web and Industry Foundation Classes-based (IFC-based) distributed computer integrated environment has been developed. This environment supports design (CAD), visualisation (VR and Drawing Web Format –– DWF), estimating, planning, specifications and supplier information. WISPER enables project information to be exchanged through a STEP Part 21 file and shared through the IFC database. Meanwhile, a set of Web pages allows for remote interaction, as well as access to and the distribution of applications. This provides great flexibility and portability, thereby enabling construction professionals to contribute as well as to perform and manage their own activities.

title	Redirecting design generation in architecture
source	International Conference on Generative Art
summary	Design generation has been the traditional culmination of computational design theory in architecture. Motivated either by programmatic and functional complexity (as in space allocation) or by the elegance and power of representational analyses (shape grammars, rectangular arrangements), research has produced generative systems capable of producing new designs that satisfied certain conditions or of reproducing exhaustively entire classes (such as all possible Palladian villas), comprising known and plausible new designs. Most generative systems aimed at a complete spatial design (detailing being an unpopular subject), with minimal if any intervention by the human user / designer. The reason for doing so was either to give a demonstration of the elegance, power and completeness of a system or simply that the replacement of the designer with the computer was the fundamental purpose of the system. In other words, the problem was deemed either already resolved by the generative system or too complex for the human designer. The ongoing democratization of the computer stimulates reconsideration of the principles underlying existing design generation in architecture. While the domain analysis upon which most systems are based is insightful and interesting, jumping to a generative conclusion was almost always based on a very sketchy understanding of human creativity and of the computer's role in designing and creativity. Our current perception of such matters suggests a different approach, based on the augmentation of intuitive creative capabilities with computational extensions. The paper proposes that architectural generative design systems can be redirected towards design exploration, including the development of alternatives and variations. Human designers are known to follow inconsistent strategies when confronted with conflicts in their designs. These strategies are not made more consistent by the emerging forms of design analysis. The use of analytical means such as simulation, couple to the necessity of considering a rapidly growing number of aspects, means that the designer is confronted with huge amounts of information that have to be processed and integrated in the design. Generative design exploration that can combine the analysis results in directed and responsive redesigning seems an effective method for the early stages of the design process, as well as for partial (local) problems in later stages. The transformation of generative systems into feedback support and background assistance for the human designer presupposes re-orientation of design generation with respect to the issues of local intelligence and autonomy. Design generation has made extensive use of local intelligence but has always kept it subservient to global schemes that tended to be holistic, rigid or deterministic. The acceptance of local conditions as largely independent structures (local coordinating devices) affords a more flexible attitude that permits not only the emergence of internal conflicts but also the resolution of such conflicts in a transparent manner. The resulting autonomy of local coordinating devices can be expanded to practically all aspects and abstraction levels. The ability to have intelligent behaviour built in components of the design representation, as well as in the spatial and building elements they signify, means that we can create the new, sharper tools required by the complexity resulting from the interpretation of the built environment as a dynamic configuration of co-operating yet autonomous parts that have to be considered independently and in conjunction with each other. P.S. The content of the paper will be illustrated by a couple of computer programs that demonstrate the princples of local intelligence and autonomy in redesigning. It is possible that these programs could be presented as independent interactive exhibits but it all depends upon the time we can make free for the development of self-sufficient, self-running demonstrations until December.

title	Evolving the Shape of Things to Come - A Comparison of Interactive Evolution and Direct Manipulation for Creative Tasks
source	International Conference on Generative Art
summary	This paper is concerned with differences between direct manipulation and interactive evolutionary design as two fundamentally different interaction styles for creative tasks. Its main contribution to the field of generative design is the treatment of interactive evolutionary design as a general interaction style that can be used to support users in creative tasks. Direct manipulation interfaces, a term coined by Ben Shneiderman in the mid-seventies, are the kind of interface that is characteristic of most modern personal computer application user interfaces. Typically, direct manipulation interfaces incorporate a model of a context (such as a desktop environment) supposedly familiar to users. Rather than giving textual commands (i.e. "remove file.txt", "copy file1.txt file2.txt") to an imagined intermediary between the user and the computer, the user acts directly on the objects of interest to complete a task. Undoubtedly, direct manipulation has played an important role in making computers accessible to non-computer experts. Less certain are the reasons why direct manipulation interfaces are so successful. It has been suggested that this kind of interaction style caters for a sense of directness, control and engagement in the interaction with the computer. Also, the possibilities of incremental action with continuous feedback are believed to be an important factor of the attractiveness of direct manipulation. However, direct manipulation is also associated with a number of problems that make it a less than ideal interaction style in some situations. Recently, new interaction paradigms have emerged that address the shortcomings of direct manipulation in various ways. One example is so-called software agents that, quite the contrary to direct manipulation, act on behalf of the user and alleviate the user from some of the attention and cognitive load traditionally involved in the interaction with large quantities of information. However, this relief comes at the cost of lost user control and requires the user to put trust into a pseudo-autonomous piece of software. Another emerging style of human-computer interaction of special interest for creative tasks is that of interactive evolutionary design (sometimes referred to as aesthetic selection). Interactive evolutionary design is inspired by notions from biological evolution and may be described as a way of exploring a large – potentially infinite – space of possible design configurations based on the judgement of the user. Rather than, as is the case with direct manipulation, directly influencing the features of an object, the user influences the design by means of expressing her judgement of design examples. Variations of interactive evolutionary design have been employed to support design and creation of a variety of objects. Examples of such objects include artistic images, web advertising banners and facial expressions. In order to make an empirical investigation possible, two functional prototypes have been designed and implemented. Both prototypes are targeted at typeface design. The first prototype allows a user to directly manipulate a set of predefined attributes that govern the design of a typeface. The second prototype allows a user to iteratively influence the design of a typeface by means of expressing her judgement of typeface examples. Initially, these examples are randomly generated but will, during the course of interaction, converge upon design configurations that reflect the user’s expressed subjective judgement. In the evaluation of the prototypes, I am specifically interested in users’ sense of control, convergence and surprise. Is it possible to maintain a sense of control and convergence without sacrificing the possibilities of the unexpected in a design process? The empirical findings seem to suggest that direct manipulation caters for a high degree of control and convergence, but with a small amount of surprise and sense of novelty. The interactive evolutionary design prototype supported a lower degree of experienced control, but seems to provide both a sense of surprise and convergence. One plausible interpretation of this is that, on the one hand, direct manipulation is a good interaction style for realizing the user’s intentions. On the other hand, interactive evolutionary design has a potential to actually change the user’s intentions and pre-conceptions of that which is being designed and, in doing so, adds an important factor to the creative process. Based on the empirical findings, the paper discusses situations when interactive evolutionary design may be a serious contender with direct manipulation as the principal interaction style and also how a combination of both styles can be applied.

title	Measuring user satisfaction for design variations through virtual reality
source	Timmermans, H.J.P. & Vries, B. de (eds.) Design & Decision Support Systems in Architecture - Proceedings of the 5th International Conference, August 22-25 2000, Nijkerk, pp. 278-288
summary	Virtual Reality (VR), and Artificial Intelligence (AI) technology have become increasingly more common in all disciplines of modern life. These new technologies range from simple software assistants to sophisticated modeling of human behavior. In this research project, we are creating an AI agent environment that helps architects to identify user preferences through a Virtual Reality Interface. At the current stage of development, the research project has resulted in a VR application - MuseV2 that allows users to instantly modify an architectural design. The distinctive feature of this application is that a space is considered as a base for all user modifications and as a connection between all design elements. In this paper we provide some technical information about MuseV2. Presentation of a design through VR allows AI agents to observe user-induced modifications and to gather preference information. In addition to allowing for an individualized design, this information generalized across a sample of users should provide the basis for developing basic designs for particular market segments and predict the market potential of those designs. The system that we envision should not become an automated design tool, but an adviser and viewer for users, who have limited knowledge or no knowledge at all about CAD systems, and architectural design. This tool should help investors to assess preferences for new community housing in order to meet the needs of future inhabitants.

summary	This paper describes Virtual Reality as an environment to collect information about user satisfaction. Because Virtual Reality (VR) allows visualization with added interactivity, this form of representation has particular advantages when presenting new designs. The paper reports on the development of a VR system that supports architects to collect opinions about their design alternatives in terms of user preferences. An alternative to conjoint analysis, that uses statistical choice variations to estimate user preference functions, is developed. Artificial Intelligence (AI) Agent technology will be implemented to build a model for data collection, prediction, and learning processes.

summary	In the era of communication, the participation in internet-communities has grown to become a motor for innovation in software and community platforms. The paper describes the hypothesis that, by creating a virtual city (or a second city) a new type of social, economic and scientific network is established, which is supported through visual communication technologies. The various users bring, per se, their own intrinsic motivation and requirements to the system. Nonetheless, a personal identification with a city/neighbourhood/house/apartment can be used to awake awareness and to foster participation. This is especially important when dealing with the city inhabitants. City modelling itself has been carried out for over a decade. Projects such as the city model of Graz have shown how city models can be established so as to be scalable for new information (Dokonal et al 2000). Furthermore, these city models have been used in the education of future architects and urban planners. The project described here moves in the opposite direction: the model moves out of the classroom to an interdisciplinary city-model-platform. The work described here is the conceptual model for a multi-dimensional data set that models the city. This has spawned a host of other projects using the model as a foundation for further interactivity development and the extension of the model itself. The paper describes the structure of the conceptual model and the first experience of incorporating diverse projects such those mentioned above. The model also is structured so as to be compatible with the XML standards being developed for city information (CityGML). The goal of the project is to create a data set describing the city that not only describes the geometry, but also the history (including planned histories) and nature of the city. In contrast to virtual realities, which attempt to create a separate world (e.g. Second Life), the Second City is intended as an interdisciplinary repository for the geometrical, historical and cultural information of the city.

title	EO-PLAN-GIS Operational earth observation applications involving user communities on national and European level
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The joint GeoVille/ARC Seibersdorf project EO-Plan-GIS has the objective of deriving Earth Observation (EO)/Geographic Information System (GIS) products for public and private customers (i.e. Austrian state governments and digital mapping industry). Representatives of three state administrations (i.e. Carynthia, Upper Austria and Vorarlberg) and of Tele Atlas (a commercial enterprise in the production of digital road databases) have been actively involved in the project activities. The major focus of the project is on the automated differentiation of built-up areas and the derivation of land use/cover data for both the state governments and Tele Atlas, as well as on the update and upgrade of the Tele Atlas road network. Using GIS methods, the EO-derived base data will be adapted to serve the individual user needs (i.e. Geographic State Information Systems and Tele Atlas MultiNet). EO-Plan-GIS was initiated by the Austrian Ministry of Transport, Innovation and Technology as a national initiative within theframework of the current GMES (Global Monitoring for Environment and Security) activities of ESA and the EU. It delivers inputs into the following GMES domains:• European Regional Monitoring, Subtopic A: Land cover change in Europe, characterisation of land cover changes (1950 –2000) in the EU with particular emphasis on landscapes and urban areas.• Horizontal Support Action – Information Management Tools & the Development of a European Spatial Data“Infostructure”.

title	The virtual construction site: a web-based teaching/learning environment in construction technology
source	Automation in Construction 10 (1) (2000) pp. 169-179
summary	Site visits form an important component in teaching/learning in many aspects of civil engineering education. However, due to scheduling and access difficulties, and the overriding need for safety, real time site visits may not be possible, and alternative approaches need to be investigated. One approach, described in this paper, is the creation of multimedia databases of actual buildings under construction. This material, suitably structured, can then be delivered through the World Wide Web or from a CD-ROM, thus creating "virtual construction sites." The web site described in this paper forms part of a much larger group of web sites developed by four Universities in Hong Kong over the past 2 years and now approaching completion. This large series of linked web sites is known as CIVCAL and provides a comprehensive teaching/learning environment for students in many aspects of civil engineering. This paper describes the web site being developed by City University within CIVCAL. The City University web site is known as the Virtual Building & Construction Environment and is designed specifically to support teaching/learning in building construction technology.

summary	Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

source	2da Conferencia Venezolana sobre Aplicación de Computadores en Arquitectura, Maracaibo (Venezuela) december 2001, pp. 194-203
summary	The policy rationale for promotion of urban development in the Mexico-Texas borderland of Nuevo León is likely to be sustained and even strengthened. The University of Texasí participation in new town planning for Colombia spans at least three hierarchical levels with students, faculty members, practitioners and government officials joining efforts. At the ìstudio levelî, students completed a comprehensive landscape assessment for portions of the future city using GPS surveying and GIS database and modeling. Graduate students, using field data, updated 2000 maps/shapefiles, and spatial modeling as an analysis tool, created a series of spatial models to produce useful information about the study areaís inherent suitability for agriculture, human settlement and preservation. This work culminated in a research symposium, planning charrette, refinement of land use and infrastructure assumptions, and the development of masterplan elements for the future city. In contrast to the professional firm, the project provides unique opportunities for intensive learning and applied research that contribute to the ecological, social and economic well-being of new cities and developing regions,

summary	New Technologies (NTs) offer us tools with which to deal with the new challenges that a changing society or workplace presents. In particular, new design strategies and approaches are required by the emerging Information Society, and NTs offer effective solutions to the designers in the different stages of their professional life, and in different working situations. In this paper some meaningful scenarios of the use of the NTs in Architecture and Urban Design are introduced; the scenarios have been selected in order to understand how the role of architects in the Information Society is changing, and what new opportunities NTs offer them. It will be underlined how the telematic networks play an essential role in the activation of virtual studios that are able to compete in an increasingly global market; examples will be given of the use of the Web to support activities related to Urban Planning and Management; it will be shown how the Internet may be used to access strategic resources for education and training, and sustain lifelong learning. The aforesaid considerations derive from a Web-Based Instruction system we have developed to support University students in the definition of projects that can concern either single buildings or whole parts of a city. The system can easily be adopted in the other scenarios introduced.

summary	BEATL (Built Environment Appropriate Technology for Learning) is a research project based on a process of module pairing and collaboration between Built Environment Faculties. It is more about how one can embed technology in pedagogically sound ways than about the technology itself. This paper describes a case study of innovative self-paced diagnostic on-line illustrated Quizzes introduced at the University of the West of England (UWE) last year and now partnered by the University of Westminster (WU). It focuses on the development of the innovation, embedding it in teaching at UWE, its transfer to WU, and the support of “Educational Technology Officers” (ETO) in each. The methodologies used for evaluating the costs and benefits of this innovation are discussed.

title	Sketch that Scene for Me: Creating Virtual Worlds by Freehand Drawing

summary	With the Web people can now view virtual threedimensional worlds and explore virtual space. Increasingly, novice users are interested in creating 3D Web sites. Virtual Reality Modeling Language gained ISO status in 1997, although it is being supplanted by the compatible Java3D API and alternative 3D Web technologies compete. Viewing VRML scenes is relatively straightforward on most hardware platforms and browsers, but currently there are only two ways to create 3D virtual scenes: One is to code the scene directly using VRML. The other is to use existing CAD and modeling software, and save the world in VRML format or convert to VRML from some other format. Both methods are time consuming, cumbersome, and have steep learning curves. Pen-based user interfaces, on the other hand, are for many an easy and intuitive method for graphics input. Not only are people familiar with the look and feel of paper and pencil, novice users also find it less intimidating to draw what they want, where they want it instead of using a complicated tool palette and pull-down menus. Architects and designers use sketches as a primary tool to generate design ideas and to explore alternatives, and numerous computer-based interfaces have played on the concept of "sketch". However, we restrict the notion of sketch to freehand drawing, which we believe helps people to think, to envision, and to recognize properties of the objects with which they are working. SKETCH employs a pen interface to create three-dimensional models, but it uses a simple language of gestures to control a three-dimensional modeler; it does not attempt to interpret freehand drawings. In contrast, our support of 3D world creation using freehand drawing depend on users’ traditional understanding of a floor plan representation. Igarashi et al. used a pen interface to drive browsing in a 3D world, by projecting the user’s marks on the ground plane in the virtual world. Our Sketch-3D project extends this approach, investigating an interface that allows direct interpretation of the drawing marks (what you draw is what you get) and serves as a rapid prototyping tool for creating 3D virtual scenes.

doi	https://doi.org/10.52842/conf.acadia.2000.003
summary	This paper examines the progressive and pragmatic use of computers and CAAD systems in the architectural practice. With the aid of three scenarios, this paper will illustrate gainful implementation of computer aided project planning in architecture. The first scenario describes an actual situation of implementation and describes conceptual abortive developments in office organization as well as in software technology. Scenario two outlines the essential features of an integrated building design system and the efforts involved in its implementation in the architectural practice. It clearly defines preconditions for implementation and focuses on feasible concepts for the integration of different database management systems. A glance at paradigms of conceptual work currently under development will be taken. The third scenario deals with the structure and integration of innovative concepts and the responsibility the architect will bear with regard to necessary alterations in office and workgroup organization. A future-oriented building design system will be described that distinguishes itself from existing programs because of its modular, net-based structure. With reference to today’s situation in architectural offices and according to realizable improvements, this article will demonstrate courses for future IT-support on the basis of an ongoing research project. The presented project is part of the special research area 524 “Materials and Constructions for the Revitalization of Existing Buildings” which is funded by the Deutsche Forschungsgemeinschaft. It deals with the integration of various parties that are involved in the revitalization process of existing buildings as well as with the provision of adequate information within the planning process resting upon the survey of existing building substance. Additional concepts that might change the way an architect’s work is organized will also be presented. “Case-based-reasoning” methods will make informal knowledge available, leading to a digital memory of preservable solutions.

summary	This paper discusses aspects of the near future, a future that in parts is already with us, a future that we need to attend to now. The focus is computer aided design, but not graphics-based CAD. Rather today's CAD innovation is focused on the use of smart communications to provide designers with an information-rich support environment and the design team with an infrastructure for co-operative working. Based on this picture of a different, emerging CAD, the paper finishes with a brief comment on educational implications. One is that the emerging commercial project information management software could prove useful as infrastructure for co-operative educational projects. Another is that there could be significant gaps in information content for educational users as education becomes more IT-based. Should providing this content be a role for joint ECAADE research and development projects?
