title	Dry-In House: A Mass Customized Affordable House for New Orleans
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 359-362
summary	Dry-in house is a mass customized affordable housing system proposed for the reconstruction of New Orleans. The dry-in House gets the owner back to their home site quickly while providing the infrastructure an occupant needs (shelter, water, electricity). The owner is supplied with an inhabitable shell that is customizable before it is fabricated as well as onsite as the project is “fitted out” over time. The key concept is to allow families to participate in the design of their customized homes and to get people back to their home sites as quickly as possible and to give them the opportunity to finish and further customize their home over time. The project addresses inefficiencies and redundancies in emergency housing currently provided by FEMA. Primarily the dry-in House as its name implies provides a timely dried-in space which doubles as a customized infrastructure for the reconstruction of homes and neighborhoods. The project is designed to meet the $59,000 life cycle cost of the presently provided temporary housing, the notorious “FEMA Trailer”. However, the Dry-in House provides a solution that: a) Is permanent rather than temporary. The house will be finished and further customized over time rather than disposed of. b) Reoccupies the owner’s home site rather than a “FEMA ghetto” keeping the community together and functioning. c) Is mass customized rather than mass-standardized allowing the owner to have input on the design of their home. The design is a “starter home” rather than an inflexible and over-determined solution. This also has the benefit of giving variation to the reconstruction of New Orleans as opposed to the monotony of mass-production. d) Allows the owners to further customize their home over time with additional exterior finishes and the subdivision and fit out of the interior. By utilizing plate truss technology and associated parametric modeling software, highly customized trusses can be engineered and fabricated at no additional cost as compared to off-the-shelf trusses. This mass customization technology is employed to create the building section of each individual’s house. The truss is not used in its typical manner, spanning over the house; rather, it is extruded in section to form the house itself (roof, wall, and floor). Dry-in House exploits this building technology to quickly rebuild communities in a sensible manner. It allows for an increased speed of design and construction and most importantly it involves the owner in this process. The process has other benefits like reducing waste not only because it replaces the FEMA trailer which is expensive and disposable but also since the components are prefabricated there is more precision and also quality. The Dry-in House allows the owner-designer to “draw” the section of their new home providing them with a unique design and a sense of belonging and security. The design of the section of the house also provides them with spatial configurations customized relative to site conditions, program etc... Because of the narrow lot configuration of New Orleans, the design maximizes the roof as a source for natural ventilation and light for the interior of the house. In addition, the house is one room deep providing cross ventilation in all rooms minimizing reliance on artificial mechanical systems. The timely and efficient off site fabrication of building sections facilitate larger concentrations of volunteers on site at one time, thereby promoting a greater collective spirit among the community and volunteer workforce, a therapeutic event for the community as they participate in the rebuilding of their homes and city. With individualized building sections arriving on site, the construction process is imagined to be more akin to a barn raising, making possible the drying in of multiple houses in less than one day.

title	Autoaprendizaje, integración transversal y diseño 3D [Self learning, transversal integration and 3D design]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 80-83
summary	The paper begins with some considerations about the historical evolution of parametric design methods in the advanced industry and their forecoming transference to the field of architecture. Following these considerations it is maintained that this transference will bring about a second revolution in the educational methodologies, more important than the first one, and that this will result in a clearer separation between conceptual knowledge and instrumental knowledge. The need to give a proper place to a growing sector of information and mechanical methods of learning in the academic world should lead to a an adequate integration of computer aided instruction, a broader collaboration between different departments and to e-learning methods established on a regular basis. In this context, an outline of a new experience of this kind, that will start next term in our school, is presented.

title	Hand-Machine Conflict and the Ethics of Digital Fabrication
source	Cheng R and Tripeny PJ (eds) Getting Real: Design Ethos Now, Proceedings of the 94th Annual Meeting of the Association of Collegiate Schools of Architecture, Salt Lake City, 2006, 207-214
summary	The introduction of machines into human affairs produces tension between competing needs. We need to engage the world directly with the hand, and we need to augment the hand with mechanical power. What is the right balance between human autonomy and mechanical influence – between direct and indirect control? With the rise of the computer age, we seem to resolve the matter in favor of machines, encouraging their unrestrained expansion. However, a Resistance Movement persists. It resurfaces with each wave of technological invention, rekindling the tension. This can be seen in the current debate over the appropriate use of digital fabrication technology. Some architects believe it yields unprecedented creative freedom by overcoming the restrictions of mass production. Others believe it alienates us from a vital source of inspiration by deemphasizing direct contact with material. This paper examines the hand-machine conflict in its current form, and argues that its polarized categories cloud our thinking with false moral alternatives such as: embrace technology and foster a new aesthetic age, or resist it and protect mankind from further alienation. Instead, we should seek a third alternative that frees us from this either-or thinking. One established way of doing this in architectural design is to use traditional media and computer media in oscillation. The paper critically evaluates this approach and presents a design studio experiment that moves beyond oscillation, seeking a higher degree of hand-machine unity.

title	Synthetic Research
doi	https://doi.org/10.52842/conf.acadia.2006.230
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 230-231
summary	Synthetic Research insinuates a relationship of a meticulous process of discovering truth contradicted against a fabricated, as in concocted, reality. It is important to recognize the logical aspect of synthetic when examining what synthetic research can provide for architectural discourse. Synthesis contrasts with analysis in that it’s primary methods involve recourse to experience; it is experience that is at the heart of synthetic research. The synthesis of theory, architectural constructions, technological artifacts and computational techniques requires experiencing the results of experimentation. Synthetic digital architecture necessitates a discovery process incorporating creation that allows for experience, be it virtual reality, full-scale prototyping or spatial creations; provided experience is a truthful one, and not disingenuous and thereby slipping into the alternate definition of synthetic.Research’s experimental arm, as opposed to the analytic, relies on tinkering - implying the unfinished, the incomplete, the prototype. Examples of this are everywhere. Computer screenshots are a strikingly literal example of synthetic research when used as a means of experiencing a process. Performance mock-ups of building assemblies are a method of synthetic research in that one experiences a set of defined performances in order to discover and redefine the project. The watchmaker craft is an exercise in research/experimentation where material properties are inherent in function and aesthetics; consider how the components interact with the environment - motion, gravity, space-time, temperature. Efficiency at this point is predominantly structural and physical. Decorative or aesthetic elements are applied or integrated in later iterations along with optimization of performance, marketing and costs.What is a architectural research? How can research synthesize the wide range of possibilities for the trajectory of architecture when engaged in digital and computational techniques? The goals, techniques, documentation and other methods of research production have a place in architecture that must be explored, particularly as it related to computation. As in other fields, we must build a legitimate body of research whereby others can use and expand upon, such that digital architectures evolve in innovative as well as prosperous paths.

title	Space, Events and Urban Performance
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 333-336
summary	This report investigates different kinds of Urban Performance in Thames Path, South Bank of Thames River. Urban Performance is defined here as the expression or manifestation of different social groups in the city space regarding the appropriation of a specific place for its spatial practices. The Urban Performances are intrinsic to the cultural expression of the city and revealed through the spatial experience of both performer and spectator. The aim of this paper is to shed light on different kind of urban performances and how are they linked to spatial and syntactic properties of space. This topic is intrinsic in the space syntax theory due its fundamental relation between spatiality and human activity. The research method used were, direct observations by static snapshots and traces (related with human movement) and a survey of potential attractors, active facades and path widths. The results were overlaid with spatial analysis in terms of performers isovists and syntactic analysis through visibility graph. The findings show a strong relation between performers’ use of space and visibility in the urban area, and a high influence of the cultural attractions and public services that works as movement attractors. The discussion is developed through the research findings and theories of spatial experience putting forward varied interpretations related with the research topic and the selected site. The report concludes that the urban performances in Thames path is determined by the human co presence in the space, due to this strategic points chosen along the path by the performers are strongly related with the visual connections in the system. Furthermore, the attractors play an important role shaping the spatial experience and urban character of the studied area.

title	Restitution and Interpretation of Spatial Representations: A New Approach for Teaching Representation
doi	https://doi.org/10.52842/conf.ecaade.2006.840
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 840-847
summary	The use of computers has changed the practice of spatial representations. The users are no longer drawers but modelers who need to be able to check the coherence of models. The teaching of representations has to adapt with this evolution, especially in Schools of Architecture. A pedagogical way is to give interpretation tools of spatial representations through projective properties (incidence or affine properties) and consequence of intrinsic constraints (parallelism, orthogonality, and symmetry). The application of this knowledge is essential for the rebuilding of existing 3D objects or for a design process, with the restitution of 3D models from sketches. These approaches are illustrated in a pedagogical way, using dynamic geometry, in the restitution of the polyhedron of the engraving “Melencolia I” of A. Dürer, and in a dynamic sketch of a skylight inspired of the Vitra museum of F. Ghery.

title	User needs at the heart of town: Orientation and appraisal in an endoscopic city scale model (script)
source	Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 115-131
summary	In this paper we provide a “work-in-progress” report on on going investigation into the perception of building alternatives at a central urban place. The city-planning task in this case involves the development of several key parcels of real estate, with significant impact on a mediumsized German city’s overall appearance and functionality. The interests of investors wishing to maximize economic utilization are competing with public interests regarding urban planning and urban design as well as development needs. Hence, there is a need for the development of different spatial layouts for the district to help identify reasonable concepts for the use of these key properties and their impact on the visual townscape as well as the functional spatial properties of the city’s open space. Ultimately, clear deed restrictions and guidelines are to be identified for future investors to preserve the cityscape and to improve the quality of the existing public open space but also to enhance downtown’s existing sensible economic equilibrium.

title	Real-time remote 3D digitizing and modelling
doi	https://doi.org/10.52842/conf.ecaade.2006.128
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 128-131
summary	This paper describes a procedure that feeds remotely a modelling system with geographical coordinates and the relative measurements taken in place in order to model dynamically new entities in real-time. The operation of this system is based on methodologies that are commonly used in telegeoprocessing – telegeomonitoring systems and its purpose is to simulate in real-time an existing environment using the captured measurements. The direct input of geographic data to the proposed system, which is adapted to a modelling environment (CAD or GIS), triggers the creation of new 3D entities in real-time (points, linear or area features), as it could be done with a traditional tablet digitizer. Simultaneously, the proposed system represents thematically the properties of the modelling entities (according to the measured values) over a 3D mesh. The aim of the suggested system is the remote registration of additional spatial information, their adequate treatment and adjustment via special developed interfaces, including their representation via developed software which is applied in the AutoCAD environment because of its programming development support and its use by a variety of engineers.

title	THE DEVELOPMENT OF AN INTEGRATED ENVIRONMENTAL BUILDING DESIGN TOOL
doi	https://doi.org/10.52842/conf.caadria.2006.x.n7f
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 557-559
summary	Environmental design implementations are generally applied within limited and specialised areas of environmental design making them difficult to use intuitively by designers (Maneesatid and Szalapaj, 2003). Building simulations have mostly focused on accurate parameters and physical properties of building elements. Such tools typically require numerous numerical data which is often only accurately known in the detail design stages. Conventional environmental building design systems (EBS) have typically required highly experienced users who are familiar with extensive qualitative input and output requirements. A successful architectural design solution that is both energy efficient and environmentally friendly, cannot be obtained simply by additively combining a set of discrete specialist analyses. A move towards better architectural design with environmental considerations can be achieved by allowing designers themselves to express relationships between salient environmental parameters that can subsequently be analysed in integrated ways. This presentation is concerned with the issues involved in developing a quick and intuitive interface for expression of relationships between environmental parameters.

title	ILUDS - An Interactive Land Use Database System for Intelligent Cities
doi	https://doi.org/10.52842/conf.ecaade.2006.276
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 276-279
summary	This paper presents the i-putra business channel, a portal that has been completed with a comprehensive database of information relating to commercial and residential properties, and other on-going development components of Putrajaya, one of Malaysia’s intelligent cities. Designers were provided with multimedia-rich information of spaces before making a selection through the Interactive Land Use Database System (ILUDS) which hosted more than 67,000 units of residential and commercial areas in Putrajaya. The database was developed based on category searching features that aimed to be the one-stop brief explanatory system on the Internet. ILUDS depicts an innovative idea for city and urban development to prepare information and virtual interactivities for a better usage in a ‘soft city’ design. The system has the underlying structure that allows for partitioning and ease of handling within which the data can be structured under a graphical interface that facilitates editing, manipulation, attribution and updating. This attribute of city information and associate data offers users a different level of interactivity and provides effective use on architectural and city information.

title	The potential of Virtual Environments as contexts for Communication
doi	https://doi.org/10.52842/conf.ecaade.2006.750
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 750-753
summary	This paper documents a study done considering Virtual Reality (VR) as a spatial representational context which supports communication. It aims to identify whether VR could be considered as a communication medium, a tool that could be used for the successful transmission of information and messages, as well as the future form, content and use of it. That is, how does communication occur in a Virtual Environment (VE), by taking into account its visual properties and spatial parameters and under which conditions communication messages are conducted via VR systems, deriving from the one part (sender) and concluding to the other (receiver). The methods selected for this study involve observation and use of questionnaires at the end of each session. An already existing Internet-based online multi-user virtual environment has been chosen as the context where this survey will be carried out, that is the site Active Worlds, http://www.activeworlds.com, which can be accessed very easy to any computer user, in a desktop form. Firstly, we investigated the time needed, depending on the complexity per case, for a user of the VR application to get acquainted with the system. We were interested to know if the meaning that we would like to communicate had either remained the same through all the time of the experience or had been “modified” in a certain way and if so, for what reason. Another issue that was examined was the way in which the spatial context in a specific VE affects the way communication occurs. The framework of the application may influence the way the person receives a message, for example by making assumptions and references that he would not have made in a different environment- outside VR. After the end of the experience, the user was invited to describe his/ her impressions, with the communication factor being stressed, that is to mean if and at what extent VR can be characterized as a communication medium, as it is mentioned above, even for limited information and messages in general.

title	Branches and Bifurcations - Building a framework for modeling with isosurfaces in Generative Components
doi	https://doi.org/10.52842/conf.ecaade.2006.868
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 868-873
summary	An isosurface is a three-dimensional representation of a constant value of a field function within a given volume. They are normally used in computer graphics to visualize data in fluid dynamics, medical imaging, geophysics, and meteorology. The advantage of isosurfaces is that they can represent all sorts of topologies. That makes them a perfect tool for modeling, branching, forking, and bifurcating objects with smooth transitions. As they work of a field function, the surface is implicit, the polygonization an approximation. This is a good base for coupling performance with precision. The task was to define a set of handles to change and model an isosurface. It had to happen through the modeling of the field function in a way that is rather intuitive but without giving up the precision one is used to have from standard NURBS/BREP modeling. The paper shows how a modeling framework for isosurfaces is implemented as a plug-in for Bentley Systems Generative Components allowing an intuitive way of exploring design variations. The implementation is illustrated with a proof of concept showing a sketch design.

title	From representational to parametric and algorithmic interactions: A panorama of Digital Architectural Design teaching in Latin America
source	International Journal of Architectural Computing vol. 15 - no. 3, 215-229
summary	This study focuses on the context of graphic representation technologies and digital design on Architectural teaching in Latin America. From categories proposed by Oxman and Kotnik and through a mapping study framed by a systematic review in CumInCAD database, it is presented a panorama of the state-of-art of the digital design on Architectural teaching in the region, between 2006 and 2015. The results suggest a context of coexistence of representational interaction and parametric interaction, as well as a transition from one to another and the emergence of the first experiments in algorithmic interaction. As this mapping shows an ongoing movement toward Digital Architectural Design in Latin America in the last decade, and points out its dynamics in space in time, it could contribute to strengthen a crowdthinking network on this issue in the region and with other continents.

title	Communicating with Space and People - Smart Interface Design for Enhancing User Awareness and Interactions
doi	https://doi.org/10.52842/conf.ecaade.2006.138
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 138-145
summary	Smart space design has become an important research paradigm because of the emerging information and communication technology, smart materials, and sensory technology. A space equipped with human-computer interfaces, communicates not only with space but also with its occupants. In previous researches, the focus was on developing smart houses which made decisions for its occupants on controlling the condition of space. However, the human tends to make choices and the subtle psychological changes of occupants may derive exceptional decisions. Therefore, this paper is aimed to propose smart interfaces in house design, i.e., the “Individual Sense” concept is introduced by examining the assumptions and cases. This research probed into how the interface is characterized by individual actions. The “Individual Sense” is implemented on the basis of commonsense for reasoning potential interactions and demonstration and discussion are reported.

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.

title	Approach to Design Behavioural Models for Traffic Network Users - Choice of transport mode

summary	Our research work concerns the development of a multimodal urban traffic simulator designed to be a tool of decision-making aid similar to a game wherein the user-player can test different scenarios by immersion in a 3D virtual city. Our approach is based on the activity-based model and the multi-agent technology. The implemented result is a hybrid simulator connecting numerical simulation and behavioural aspects coming from real data. This paper is focused on two points: firstly, we introduce how a final user (the traffic regulator) instantiates and assembles components so as to model a city and its urban traffic network; secondly, we present the use of Dempster-Shafer theory in the context of discrete choice modelling. Our approach manipulates input variables in order to test realistic representations of behaviours of agent categories in a decision-making process. The traffic modelling is based on a questionnaire elaborated from standard arrays of Taguchi. The significant variables and interactions are determined with the analysis of variance which suggests a reduced model describing the behaviour of a particular social category. The belief theory is used to take into account the doubt of some respondents as well as for the preferences redistribution if the number of alternatives changes. The effects of external traffic conditions are also quantified to choose a 'robust' alternative and to use the agents' memory.

summary	The relative contributions of five variables (Stereoscopy, screen size, field of view, level of realism and level of detail) of virtual reality systems on spatial comprehension and presence are evaluated here. Using a variable-centered approach instead of an object-centric view as its theoretical basis, the contributions of these five variables and their two-way interactions are estimated through a 25-1 fractional factorial experiment (screening design) of resolution V with 84 subjects. The experiment design, procedure, measures used, creation of scales and indices, results of statistical analysis, their meaning and agenda for future research are elaborated.

summary	In Taiwan, the National Science Council (NSC) has launched the “National Digital Archives Program” (NDAP) since 2002. We participated in two projects: “The 3D digital museum of Taiwan city and architecture” and “Digital model database and professional service for Taiwan city and architecture”. The first one attempted to build a virtual museum for Taiwan city and architecture through the past four hundred years. The second one was a value-added project which intended to further apply the digital contents of the previous one. This project was consisted of 3D refined data, digital knowledge database, and architecture professional service. We were responsible for the 3D refined data. As a result, the digital model database included three cities: Hsinchu, Chiayi, and Tainan, as well as sixty-four architecture models. The interactive entertainment platform is an important leisure in our daily life. In general, the interactive entertainment includes five types: arcade game, PC game, on-line game, TV game, and mobile entertainment. This research pays attentions to the arcade game which presents dynamic interactions between machine and users. Following the improvements of design techniques, we have opportunities to experience many arcade games with different purposes, such as drum game, dance game, and fishing simulator. However, we further apply the digital model database to create an interactive entertainment platform for a racing arcade game.

title	Enhancing Interaction in Architectural Presentations with Laser Pointers
source	International Journal of Architectural Computing vol. 3 - no. 4, 503-517
summary	In a common meeting environment with projector-and-screen settings, the discussion may be dominated by a presenter who has the control of the content displayed. Although frequently used for architectural discussions, this digitally-engaged setting may not be optimal in its support of participation and discussion of design ideas. This paper presents a novel use of laser pointers to enhance the interaction in architectural presentations. A laser pointing system designed for a projector-and-screen environment was developed. To compare the performance of the laser pointer with other interaction devices, a controlled user study was carried out to test the efficiency of different devices in point-and-selection interactions. The usability of the system was also tested in a design critique. These two tests show that laser pointer is useful and able to encourage participation in group discussions. Details of the laser pointing system, the experiments and the results are reported in this paper.

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.
