title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

title	Diffusion of research & development (RD) results with the help of new information and communication technologies (NICT)
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 42-47
summary	This work has the objective to post some discussions about the usage of media and communication technologies with respect to dissemination, diffusion and commercialization of RD products. With the help of a documented analysis, a system is proposed for the research and diffusion of the products generated by IDEC, to allow these products transfer, commercialization and appropriation on the part of users, in order to improve the conditions of habitability, quality of life and sustainability applicable to the construction techniques of the users own houses. Part of the concept is that the NICT are not good per se, but because of their potential to create powerful institutional, economic and social networks. Within this context, this work presents the advances achieved so far with respect to: 1. Analysis of production and information processes used for the diffusion of researches and development; 2. Current importance and limitations of intelligent systems of information diffusion; 3. Its application. " [Full paper in Spanish]

title	Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary	The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

summary	As the field of computer-aided design evolved over the last thirty years or so, it has witnessed five changes of emphasis in research direction. In the first stage, the use of computers in architecture focused on the development of Computer Aided Design (CAD), that is, systems that simulated the use of drafting tools, and research was mainly concerned with the satisfaction of designers' ergonomic needs. In the second stage, there were efforts to use computer tools in non-graphical aspects of designing, such as the use of Data Base Management Systems (DBMS) in the quantity survey of buildings. The concern was to satisfy the cognitive needs of designers by focusing on the way information and knowledge were perceived, acquired, stored, and processed. In the third stage, the focus shifted to the development of realistic models of buildings to permit the assessment of design proposals. In the fourth stage, the focus was on studies concerned with the encoding of architectural knowledge into design tools (KBMS), and the discussion was whether to go towards design automation or design supporting tools. In the fifth stage, with the advent of the Internet and the development of communication tools, research became focused on the collaborative and social aspects of design activity. In recent years, research also became concerned with the exploration of the physical implications of digital media in the production of artefacts. Today, there is a vast range of research interests and approaches, but the quest for new, unifying paradigms continues.

summary	Learning Management Systems (LMS) embody spaces that combine Virtual Classrooms, learning communities, repositories of educational resources and communication devices. The use by faculty members and students, in a campus containing the schools of Architecture, Design and Geography, of Open Source LMS MOODLE, during the years 2005-2006, was assessed. An analysis of the Digital Vestiges, the metadata in the logs database, distinguished between the levels of informative and communicational interaction. The results draw attention to a trend, similar to previous measurements in Latin America, of more use of ICT educational resources for informational purposes than communicational interactions between teachers and students.

summary	One of the major challenges facing the professionals involved in the home modification process is to succeed in adapting the environments in a way that enables an optimal fit between the individual and the setting in which he or she operates. The challenge originates primarily from the fundamental characteristic of design - one can see and test the final result of home modifications only after they have been completed. The goal of this study was to address this problem by developing and evaluating an interactive living environments model, HabiTest, which will facilitate the planning, design and assessment of optimal home and work settings for people with physical disabilities. This paper describes the HabiTest tool, an interactive model that has been implemented via an immersive virtual reality system which displays three-dimensional renderings of specific environments, and which responds to user-driven manipulations such as navigation within the environment and alteration of its design. Initial results of a usability evaluation of this interactive environment by users are described.

summary	Planning workshops are known to provide important opportunities for citizen’s participation in environmental planning. The digital camera is a convenient tool for such workshops though participants still face difficulties in smooth sharing of information amongst themselves. The authors developed a prototype system for a planning workshop that applies the web-GIS technique, and devised techniques for the system-applied planning workshop through a case study. This paper discusses, first, an assumed procedure for place studies at a planning workshop; second, the functional features of the developed system; third, arrangements for the environment of the workshop; fourth, an experiment of the system use with an urban design workshop in which 91 students participated, forming 16 teams; and finally, assessment of the operational ability of the prototype and necessary refinements for in the next version.

title	DecoSketch – Towards Calligraphic Approaches to Interior Design
doi	https://doi.org/10.52842/conf.ecaade.2005.665
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 665-670
summary	Computer-Aided Design tools have long played an important role in architecture design. However, we need to go beyond direct manipulation to devise new tools that will expedite the interior design and decoration. Indeed, conventional CAD systems, while providing ever increasing functionality, do not provide equal support to the drafting and drawing tasks. This makes even the simplest drawings a complicated endeavor. Draftspeople struggle with different concepts that those learnt from their earlier days in school and have to think long and hard to translate familiar sequences of operations to commands which require navigating a dense jungle of menus. The term calligraphic interfaces was coined by us to designate a large family of applications organized around the drawing paradigm, using a digital stylus and a tablet-and-screen combination as seen most recently in Tablet PCs®. Using these, users can enter drawings in a natural manner, largely evocative of drafting techniques that were perfected for pencil-and-paper media. This paper presents a simple calligraphic interface to explore interior design literally from the ground up. The Decosketch application is a modeling and visualization tool structured around 2 _D architectural plants. Its purpose is to help architects or customers easily creating and navigating through house designs starting from the floorplan and moving to their three-dimensional representation. Moreover, both 2D and 3D representations can be independently edited, providing a natural interface that tries to adhere to well-known representations and idioms used by architects when drafting using pencil and paper.

title	Generative Design Systems for Housing
doi	https://doi.org/10.52842/conf.ecaade.2005.501
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 501-506
summary	The present paper describes an undergoing research that aims at developing a generative design computer implementation with an outside-in approach, OIDS. The system will allow developing and visualizing context-based housing development designs. This approach will include both natural characteristics of the site and the existing neighboring buildings. It is argued that certain common urban design practices are the result of a simplification due to difficulties in dealing with the irregularities of the natural environment, which often requires the use of time-consuming methods. The computer-based application will provide tools for dealing with such difficulties, allowing designers to describe their own design rules. In an initial phase of the project, a tool that can subdivide irregular land parcels into equally sized areas has been developed. In further stages, other environmental variables will be addressed, such as solar aspect and prevalent wind directions. Eventually, even the designs of interior layouts should result from exterior forces. The resulting generative system is expected to facilitate and encourage the use of a more organic approach to building siting and design, bringing about the important discussion about which should be the main forces in the generation of the built environment.

title	Creative Design Between Representation and Simulation

summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

title	Assisting 3D Modeling from Documents
doi	https://doi.org/10.52842/conf.ecaade.2005.467
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 467-476
summary	This paper presents research in computer modeling that ARIAM team of the school of architecture of Paris La Villette has been developing for several years. One of the aims of this research group is to develop computer systems that assist architects in modeling existing buildings or monuments from heterogeneous documents or data as drawings plans, sections, photos, measures taken on site etc. In spite of advances in computer recognition it’s a long way to have a system that could automatically recognize, from any bitmap document or photo, relevant architectural objects and automatically build the model these documents represent. However, if we could define a knowledge base about a particular domain, it would be possible to develop a system that could interpret specific documents that represent some kind of building or monuments. But, even in such limited domain, it is difficult to build an exhaustive knowledge base and user-interactions are generally required. We argue that a user could mark relevant information on the documents and thus facilitate the process of interpreting. The system we propose has three components: a graphical user interaction tool, an analyzer of documents and user interactions, and a generative tool that produces the required model. As an illustration, the paper presents a system we have developed which assists an architect in modeling a 3D mesh of gothic vaults for a finite elements analysis.

summary	In this paper we attempt to develop a new system called “C-Navi” for construction site simulation and management system. By integrating AR technology with mobile computing, the new system will extend the abilities of AR systems to be implemented in large outdoor space. The concept of 4D CAD system is utilized by integrating related information and displaying them in the time-based visualization approach. Our system could help with decision making and also act as a tool for improved communications between project partners.

title	A cooperative model using semantic works dedicated to architectural design
doi	https://doi.org/10.52842/conf.caadria.2005.094
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 94-104
summary	Architectural cooperative design as well as information modeling have been active research areas for several decades. The use of systems adapted to the cooperative design assistance for the building domain is complex. This results from the complexity of the cooperative work (difficulties in tracking actor’s work, lack of most of the required information, coordination problems, implicit nature of most of the construction activities, etc.) The main objective of our research in these domains is to develop a tool that helps the management of a building project and aids cooperative design. So, in the first part of this article, we propose to view the exchanging data mode and cooperation tools in the building domain. The second part of this article illustrates the existing cooperative design models. Then we justify the interest shown in a new model of cooperative design where the relational organization of the project and the semantic meaning of works are taken into account. Finally, we use this new model for defining a design-aided tool, to deduce advantages and limits of the “Virtual Cooperative Project”.

title	Baking Light: Global Illumination in VR Environments as architectural design tool
doi	https://doi.org/10.52842/conf.caadria.2005.214

summary	As proven in the past, immersive Virtual Environments can be helpful in the process of architectural design (Achten et al. 1999). But still years later, these systems are not common in the architectural design process, neither in architectural education nor in professional work. The reasons might be the high price of e.g. CAVEs, the lack of intuitive navigation and design tools in those environments, the absence of useful and easy to handle design workflows, and the quality constraints of real-time display of 3D models. A great potential for VR in the architectural workflow is the review of design decisions: Display quality, comfortable navigation and realistic illumination are crucial ingredients here. Light is one of the principal elements in architectural design, so design reviews must enable the architect to judge the quality of his design in this respect. Realistic light simulations, e.g. via radiosity algorithms, are no longer the domain of high-end graphic workstations. Today's off-the-shelf hardware and 3D-software provide the architect with high-quality tools to simulate physically correct light distributions. But the quality and impression of light is hard to judge from looking at still renderings. In collaboration with the Institute of Computer Graphics at our university we have established a series of regular design reviews in their immersive virtual environment. This paper describes the workflow that has emerged from this collaboration, the tools that were developed and used, and our practical experiences with global-light-simulations. We share results which we think are helpful to others, and we highlight areas where further research is necessary.

title	Analogous Models and Architecture

summary	Among the many possible ways of classifying the concept of “modelling”, Maldonado refers to “homologies” when structure but not shape and function are similar; “analogies” when structure and function are similar, but not shape; and “isomorphisms” when structure and shape are similar, but function may or may not be similar. Traditional artistic representation would basically fall into the category of isomorphisms, whilst analogous models are to be found mainly in activities such as magic, play or industry. Other ways of representing reality, such as architectural models or drawings, are also traditionally regarded as isomorphisms. In the course of the last century, this panorama has been altered somewhat by the post-industrial or second industrial revolution in computing and communications. Using mathematical algorithms, the computing tool has an enormous capacity to describe things of extremely diverse nature: from the shape of everyday objects to relatively complex human behaviours, these can all be described using the common language of bits. Alongside developments in computing, the world of communications has been providing us with increasingly advanced means of transmitting information, including sophisticated systems capable of emulating our own perceptions. This paper is intended as a contribution to the theoretical debate conducted over recent years on the considerable shift that has occurred in architectural representation techniques. The analysis that follows highlights a two-fold change in traditional representation techniques: on the one hand, a change in the nature of the model (as is discussed in this paper); and on the other, a modification of the interfaces or communication and perception mechanisms of the model. The conjunction of these two factors has led to the emergence of representation modes that can no longer be regarded simply as isomorphisms of reality. Insofar as virtual spaces have the capacity for us to move, to interact, in short to inhabit them, they should be regarded as “analogous models” of architectural space. In other words, there has been a shift away from representation modes based on illusion in favour of those based on simulation.

summary	The system proposes to apply the results of the investigation in the task of architecture de-structurizing the idea in order to free the capacity of thought. One works in a three-dimensional way with models built, using discarded material. It is processed by means of digital media, giving a series of images which have been selected. One uses on them different systems of lighting changing the number of lights, the position in space and the distances. Like that one obtains different shadows on a surface; those shadows work in similar form with “eyes” of possible architectural forms. They are digitally processed according to the desired objectives. Several of them are combined adding and removing elements, which makes them dynamic in time. This technique tries to develop a new tool for students who may find the idea spontaneously, with the freedom of thought in three-dimensions like a new form of looking at architecture.

title	Cornucopia Limited: Design and Dissent on the Internet
source	MIT Press: Cambridge, Mass
summary	The Internet provides a remarkable demonstration of the persistence of the gift in contemporary commerce. Net enthusiasts seem prepared to donate much to the common good. This generous spirit ought to strike resonances with the culture of design, which generally promotes a creative ethos of generosity, conspicuous display, and exuberance. But the cornucopia of the gift economy is offset by net culture's recent leanings towards consumerism. This book challenges the supposed gift society of the Internet, and supplants the gift by a more compelling metaphor, enjoyed in certain quarters of contemporary design, that of theft, rule breaking, and transgression. The relationship between design thinking and the network economy is characterized by the reckless spirit of the trickster, the crosser of boundaries, and the malingerer in the hybrid and uncertain condition of the threshold. The book thus presents a designer's view of the network economy, drawing on insights from design theorists, economists, philosophers and cultural theorists. It provides valuable insights for theorists of human-computer interaction, architects, designers, and those interested in registering the source and direction of the impulse to create, innovate, and design. The book examines five metaphors: household, machine, game, gift and threshold. Economic theory is grounded in the household. The romantics and Marx claimed that labor is dominated by the rampant machinery of capitalism. The computer game represents a potent exemplar of new media economics. The gift is presented as precursor to commercial exchange. Coyne subjects each metaphor to scrutiny in terms of how it deals with the threshold, in other words as it is dissected by the cynic or manipulated by the trickster, and other liminal dwellers in the network economy. 'What’s shaping the culture of the Internet? This turns out to be a surprisingly tricky question, one that Richard Coyne explores with verve and erudition.' --Albert Borgmann, author of Holding On to Reality

summary	Over 10 months ending in July 2005, architecture students from Aachen, Karlsruhe and Weimar took part in a design studio that differed significantly from other studios in that the result of the studio was a 1:1 realisation of the design. This is part of an evolution of the virtual faculty of architecture “Liquid Campus”, founded in 2001, which has seen the complexity of the projects steadily rise and this continued in the Project “Ein Fest: Ein Dach”. The integrated studio is arranged to encourage an active, economic and transparent learning process, which encompasses design, communication and cooperation issues. The stated goal at the beginning of the two-semester process is to build and although only a few of the ideas are realised, all participants are involved in the realisation. In this case, the project was to create “roofs” for an open-air concert for 200,000 people in Karlsruhe, Germany. The planning was carried out using the Netzentwurf platform, with which the authors have several years experience.
