title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

title	Efficiency of Lightweight Structural Forms: The Case of Treelike Structures - A comparative Structural Analysis
source	Vienna University of Technology; Building Science & Technology
summary	This work addresses the structural efficiency of lightweight tree-like structures for three case studies: Stuttgart Airport, Beaverton Library, and Thermal Bad Oeyenhausen. The case studies are simulated using Build simulation software, to determine the stresses induced in each structure. The material efficiency and shapes areexplored in terms of load bearing structures. Hybrids of the above structures are formed to compare the pattern morphology used by various types of tree-like structure and assess the structural behavior. In addition, (steel, wood and concrete) materials are compared to determine which would have better structural performance. In order to show the resemblance between the growing trees and the tree-like structures, an example of both cases is simulated and stresses evaluated. Results show that, in general, the minimum stress and deformations are obtained for steel. Structures made out of this material also exhibit higher load bearing capability, optimum stability factors and the best geometric efficiency, inspite of higher specific weight (10 times wood, and 3 times concrete).

title	Foam Structures: A Comparative Structural Efficiency Analysis Based on the Building Case "Watercube"
source	Vienna University of Technology; Building Science & Technology
summary	Foam structure in macro-scale has arisen as a new type of large span building structure recently which is a product of cooperation of advanced structural design, radical architectural design approach, and computer and software technology, and efficiency of foam structure became an important question to answer which could help further structural improvements. This study analyses efficiency of large span foam structure relative to conventional large span building structures with a parametric simulation method. Space frames are a special case of conventional large span structures one compared with foam structures, because it satisfies criteria such as being lightweight and three-dimensional as foam structure. Analysis is based on the comparison of base cases of foam model and space frame model, which are developed on light of real projects the Water Cube and the Symbol Zone of Expo’70, based on the parameters structural depth, weight and displacement, and vertical and horizontal load cases. During the analysis structural behavior of base cases were simulated by using a special structural behavior simulation program. It was found that foam model is more efficient than space frame model in terms of structural depth which is an important issue for large span building structures from both architectural and engineering point of view. Capability of spanning large distance with significantly less structural depth makes foam structure a preferable, new generation, steel structure for large spans. Moreover, the development process of base case foam model demonstrated the critical importance of geometrical design concerns of foam structure. Structural behavior simulations were exposed that structural optimization is one of the vitally important process of structural design of the foam structure.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	The Adjacency Topological Model for Housing Layout and Its Generating Algorithm, Based on the Case Study of Chinese Apartment Layouts Since 90s
doi	https://doi.org/10.52842/conf.caadria.2007.x.r9v
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Our research deals with the problem of space layout planning and chooses the Chinese apartment layouts_since 90s_ as our case study objects. A new kind of data structure for building layouts is proposed which records the adjacency topological information of layouts. The most important quality of our model is that its phenotype corresponds to our visual perception about space layouts which makes possible the morphological analysis and layouts generation. Based on constraint satisfaction techniques the Generating Algorithm focused on enumerating all the possible topology models, under the constraints of program for a new housing layout design. A case study is presented before the conclusion is given.

title	Analysis of Design Support for Kinetic Structures
source	Vienna University of Technology; Building Science & Technology
summary	This thesis attempts the formation and systemization of a basis of knowledge and information, which is indispensable to turn a design support for kinetic structures into representation by means of a 3d animating program. Representation of kinetic structures by means of the existing ordinary software sources is possible; Nevertheless, such representation lacks of different important features and functions and results eventually in the total absence of a real model of the construction, which is valuable to the user of the program especially in the field of the kinetics, where everything depends on the movement: design not only requires, but demands for visualisation. A personal interest in kinetic architecture and therefore in the physical movement of structural elements in a building, as well as an attempt to “fathom” the possibility of changing this concept to visualization and modern reality by the use of a software are the main incentives of this master thesis. First, a general research will be performed in order to check the existence of similar or semisimilar proposals. The area in which the research will be held is the Bibliography in kinetic architecture and parametric design. A comparison of animation and 3D prototype software in well-known programs will focus on whether virtual weather conditions are considered as a parameter to the animation of the structure of the programs and case studies of several existing kinetic structures will be performed, in order to point out flaws and/or helpful commands in the programs in connection with the presentation of kinetic architecture. Criteria for the choice of the software: ability to customise and to produce geometric modelling, animation in relation to time (video animation) and the simulation after taking into consideration weather factors. Finally, using the computer and the scripting language, based probably on the theory of parametric design and primitive instancing, a realistic simulation of different elements will be performed in relation to variable measurements of luminance, ventilation and temperature so as to render feasible the construction of a whole structure. The results of the thesis will be used in the future as the basic knowledge in the creation of software for simulation of kinetic architecture. This program will be used as a tool for the architect to present a building, where kinetic architecture will be applied and to create simulation of the kinetic movement through a library of the existing prefabricated elements which will be created with the help of this thesis.

title	A framework towards designing responsive public information systems
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 767-782
summary	"Evolving effective responsive systems, and creating a credible interface between the work and the user, requires an awareness of many different types of user, contexts and functions as well as the phenomenological aspects of social and environmental conditions." (Bullivant, 2006). Responsive design and interactive architecture operates at the intersection of Architecture, Arts, Technology, Media Arts, HCI and Interaction Design in a physical context suggesting ways in which the existing physical environments can be augmented and extended adding a greater level of depth, meaning and engagement with the world around us. Through a series of case studies, this paper explores a number of principles which may be applied to the design of responsive environments of which public information systems form part. Divided into three main sections, the paper first explains how responsive environments have addressed the application of public information systems, secondly, through a series of case studies, precedents are highlighted which lead to development of principles for developing designs for responsive environments. The third section discusses and elaborates on these principles which have been developed based upon our own interpretations and grouping of precedents and approaches towards interaction design. This paper contributes towards the field of responsive environments and interactive architecture through an analysis of case studies to infer a framework from which responsive environments may be created and developed.

title	An overview of virtual city modelling: emerging organisational issues
source	CUPUM07 10th International Conference on Computers in Urban Planning and Urban Management, Iguassu Falls, Brazil, 11-13 July 2007
summary	This paper presents a recent overview of the increasing use of Virtual Reality (VR) technologies for the simulation of urban environments. It builds on previous research conducted on the identification of three-dimensional (3D) city models and offers an analysis of the development, utilization and construction of VR city models. Issues pertaining to advantages, barriers and ownership are identified. The paper describes a case study of the development of a VR model for the city of Newcastle upon Tyne in the UK and outlines the role that academic institutions can play in both the creation and utilization of urban models. The study offers a new approach for the creation, management and update of urban models and reflects on issues which are emerging. Areas for future research are discussed.

title	Crossing the Cultural Divide: A Contemporary Holistic Framework for Conceptualising Design Studio Education
source	CONNECTED 2010 – 2ND INTERNATIONAL CONFERENCE ON DESIGN EDUCATION 28 JUNE - 1 JULY 2010, UNIVERSITY OF NEW SOUTH WALES, SYDNEY, AUSTRALIA
summary	While the studio is widely accepted as the learning environment where architecture students most effectively learn how to design (Mahgoub, 2007:195), there are surprisingly few studies that attempt to identify in a qualitative way the interrelated factors that contribute to and support design studio learning (Bose, 2007:131). Such a situation seems problematic given the changes and challenges facing education including design education. Overall, there is growing support for re-examining (perhaps redefining) the design studio particularly in response to the impact of new technologies but as this paper argues this should not occur independently of the other elements and qualities comprising the design studio. In this respect, this paper describes a framework developed for a doctoral project concerned with capturing and more holistically understanding the complexity and potential of the design studio to operate within an increasingly and largely unpredictable global context. Integral to this is a comparative analysis of selected cases underpinned by grounded theory methodology of the traditional design studio and the virtual design studio informed by emerging pedagogical theory and the experiences of those most intimately involved – students and lecturers. In addition to providing a conceptual model for future research, the framework is of value to educators currently interested in developing as well as evaluating learning environments for design.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 196-199
summary	This paper focuses on the study of parametric modeling using a BIM tool for conceptual design. In order to understand the use of BIM in the architectural design process, we compare the process of detail design and concept design using a BIM-based parametric tool. We present the results of two empirical studies: the design of a parametric curtain wall system, based on the work of 3 student teams; and the design of a parametric kinetic component, based on the work of 5 individual students. A comparative analysis of both processes is used to derive a process model.

title	A Computational Framework for Theater Design
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 165-182
summary	This paper presents the results of an ongoing research on computational methods for the design of theatrical spaces. We demonstrate a systemic approach to design supported by a set of digital tools implemented for assisting the process. The primary purpose of the framework is to establish a formal basis for expressing and exploring explicit design criteria. At this stage the framework enables us to metrically access a range of design metrics that traditionally have been addressed through primarily architectural narrative. Moreover, our method strives in establishing a background where knowledge can be explicitly encoded and the results of analytical methods can be additively employed. In the future, the framework will assist as the platform for experimenting with generative or query-based design processes empowered by computation. We structured this paper / framework around three conceptual units: (a) a design intent toolkit assisting the processes of rapidly generating theater configurations; (b) an analytical system that evaluates a range of design metrics centered about aspects of visual comfort; and (c) a post-processing and visualization unit that binds the design metrics with existing data / studies and provide a range of representation methods. Overall, the methodology adopts existing knowledge in theatrical design, challenges traditional ideas of understanding the theater and proposes methods for evaluating its architectural performance. The conclusions focus on highlighting both the limitations and the potential of our system in the process of theater design. We also extend outside the boundaries of the current research into a brief discussion on the methodological impact of digital technology in architectural research. Finally we propose areas of future research and development.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	Using Social Network Analysis for Visualising Spatial Planning During Conceptual Design Phase
doi	https://doi.org/10.52842/conf.caadria.2007.x.i8r
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Spatial diagramming exercises with clients are difficult when most clients are not able to visualize the end results of their requirements. This paper would like to introduce a computational tool—Social Network Analysis (SNA)—commonly used in the communications field to study relationships between people we believe can resolve this visualization problem. Our research intent is to affirm whether or not we can use SNA as a spatial planning tool during conceptual building design. We posit that since the nodes and structural relationships between the nodes may have similar architectural characteristics, the tool would enable architects to make changes by moving any spaces on a floor plan while safely maintaining their spatial relationships to other spaces. In this paper, we would like to develop a proof-of-concept model using an available SNA tool to facilitate spatial diagramming visualization during conceptual design phase. We tested the use of a SNA tool at four levels. The first level determined whether we could develop spatial relationship between functional spaces (such as the living room must be adjacent to the front entry). The second level is on setting priorities values for the different nodes and the linkages. The third level determined whether we could develop grouping relationship between several functional spaces that have a common characteristic (such as public versus private spaces) on one horizontal plane. The final fourth level determined whether we could develop multiple layers that are connected by one common connector (such as a staircase in a double-story house). Our models are validated intellectually by visual comparison between our model and another diagramming by Nooshin (2001) that was developed manually. We are most interested in the fourth level because complexity in the spatial diagramming exercises is caused by multi-layered spatial arrangements at the horizontal and vertical planes. We expect our study to provide us guidelines in developing a prototype for a spatial diagramming tool using SNA, which architects can use to resolve visualization problems when conducting the exercise with their clients.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	Sigradi 2007: Communication in the Visual Society [La Comunicación en la Comunidad Visual]
source	Proceedings of the 11th Iberoamerican Congress of Digital Graphics Graphics / ISBN 13 978-968-7451-15-2] México D.F. - México 23-25 October 2007, 467 p.
summary	In a simple communication model we must talk about the understanding between participants. This is the result of a continuing connection and a dialog of agreements and disagreements in order to arrive at sharing an idea. However, society today is in an evolutionary lapse at an accelerated pace that interjects itself in this process. It is here where social forces distend and generate important ruptures between generations and individuals that fight to prevail or impose new languages and lifestyles. Today's society has become a visual society whose effect has been reinforced through technology in the devices that we use on a daily basis. The daily use of technology and its new languages has marked a disconnection between individuals that must be closed by using a new acculturation and teaching models. Disconnection is a omnipresent modern phenomenon that can be felt as the main effect in what specialists call the digital gap. This gap not only separates generations, but also ideologies with respect to the form in which we perceive, transmit and teach in our society today. This disconnection can be easily understood through a school system that has been designed for a manufacturing and agricultural world. However, many sectors within our society have been in state of constant change and evolution. This situation generates many opportunities where an agile society is required in response to these new local and global challenges. The students of today have, for example, multi-tasking abilities that better assimilate these changes. The researchers, Ian Jukes and Anita Dosaj refer to this disconnection as the result of poor communication between digital natives (our present-day students) and digital immigrants (many present-day adults). This phenomenon results in the fact that parents and educators speak the digital dialect as a second language, and because of that are lacking in their models of communication. For example, digital natives prefer a variety of sources with rapid access, while the digital immigrants prefer slower, more controlled sources that are limited and regulated. Nowadays, our educational or production activities in which we find ourselves immersed on a daily basis cause us to participate in a wide range of processes of production, dissemination and analysis of visual forms as part of our final product or service. Much of the work that we elaborate in movies, video and photography explore meaning, perception and communication in context as well as anthropological and ethnographic themes. Using this framework for our society today, the importance of the search for the promotion of the study of visual representation and the media for the greatest development and generation of benefits is brought to the fore. Through the use of images we can describe, analyze, communicate and interpret human behavior. All these settings, full of digital disconnections and reencounters, impact on all the visual aspects of culture, including art, architecture and material objects, influencing the bodily expressions of human beings. We have created a visual society when we put emphasis on the meaning and interpretation of all we receive through our visual sense. Wherever we look, we find objects that have been modified beyond their primary function to communicate messages. In this ecosystem we are consumers and suppliers. The communication and research needed to achieve reconnection, as well as the creation of new forms of production and visual understanding, are the themes on which the works contained in this edition are centered.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 78-82
summary	This work proposes the studies of Virtual Reality (VR) as a potential system for developing methodologies for projects in IOS – Information and Orientation Systems for environmental graphics of enclosed public places, wherein the social complexity is demanded by and for different social levels. Indeed, it embraces the studies of the icon visual retraction between the 3D environments to the 2D reality, considering the computer media as a bi dimensional support. This method allows implementing experiences in sensorial, accuracy and analysis of ergonomics on IOS projects.

title	Simulation Software Development for Urban Landscape Possibility Analysis
doi	https://doi.org/10.52842/conf.caadria.2007.x.u9u
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This research paper proposes a simulation software development for possibility analysis of urban landscape development project. Normally, analysis of land potentiality and feasibility study for investment are necessary pre-processed for supporting urban planning, developing and architectural designing. However, most available tools are usually tailor made for each process individually, causing difficulties in information interchange between each processes. In this research, we propose a policy making support system for urban planning project development providing several functions such as testing land use and its physical character which are important to urban expansion and architectural design based on impact analysis of urban comprehensive plan. The proposed integrated system consists of a topological analysis module, constraint checking module and geographical information processing module. First, Geographical information stored in 3D graphic file format is converted to object-oriented data model and stored in a database. With several constraint and regulations, the stored information is then checked in the landscape topological analysis module. In evaluation process, the developed software is tested with geographical information of Bangkok area under constraints and regulations of Building Control Act of Thailand. While controlling building properties, the software can model the buildings and generate urban physical character. The result is then checked by several urban landscape planning experts. Experimental result shows that proposed system provides flexibility in information interchanging with constraints and regulations updating without system reconfiguration. The system also provides internet accessing for public participation in the process of making urban comprehensive plan.

title	Three dimensional isovist analysis method [Método de Análisis Tridimensional con isovistas]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 174-176
summary	This paper presents a three dimensional method of isovist analysis implemented in the MaxScript programming language. The script accepts as its input a standard three dimensional model of the buildings and terrain being analyzed, upon which a N×N grid is projected. Each square of this grid is assigned a height value, thereby producing a simplified surface description which is amenable to mathematical analysis. A three dimensional isovist is then generated for each grid square, by placing an observation point 1.5 meters above its center and finding the intersection of a series of rays from this point to the input model. The distance from the observation point to the intersection is summed over for all the angles studied giving a compound isovist measurement for the grid square under consideration.

title	Towards an History of Computational Tools in Automated Architectural Design - The Seroussi Pavilion Competition as a Case Study
doi	https://doi.org/10.52842/conf.caadria.2019.2.581

summary	The present research proposes a method to analyse computational tools at the architect's disposal and the potential technical bias they induce in architectural design. Six case studies will be used as a demonstration of the method's ability to highlight those biases and how architects and designers manipulate those tools to translate their architectural expertise into algorithmic design. Those case studies are the six answers to the Seroussi Pavilion competition, organized in 2007 by Natalie Seroussi, a Parisian gallery owner. Having a keen interest into computational design, she invited six architectural practices specializing in this field. As the six case studies answer the same design brief, it represents a particularly suitable opportunity to analyse the intricate relationship between architectural constraints, their translation into computational data and instructions and the programming tools used to do so. Through the analysis of four different aspects of the project - algorithmic tools/method, computational set-up, organizational chart and architectural design - several issues of the computational turn in architecture are discussed.
