title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title A study about facades from historical brazilian town using shape grammar
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary Shape grammars have been used in architecture for analysis and synthesis - in the first case, mainly for the characterization of styles and in the later for the generation of novel compositions. The present research proposes the use of shape grammars for establishing guidelines for the requalification of historical areas that have lost their original characteristics due to improper renovations. The use of shape grammars proposed here starts with the definition of a set of rules for characterizing the original style of an area. Based on these rules, the main characteristics of the area are confirmed, such as siting, proportions between walls and openings in the façades, overall dimensions constraints, and so on. Next, the rules of the grammar are transformed, to allow the use of contemporary building materials, as well as the incorporation of contemporary living styles in the new design. Rules must take into account two cases: original buildings that have been inadequately transformed, and buildings that have been completely torn down and will replace been completely replaced by new constructions. Both cases need to be harmonious with the remaining original buildings, however without simply copying the existing style. In both cases, rules have been used to establish the guidelines for the renovations, which resulted in modern urban environments that resemble the original historical sites in terms of spatial relations and proportions. They also create an appropriate environment for the observations of the preserved original buildings, which would otherwise look like aliens in a completely transformed neighborhood. The latter case is very common in most Brazilian cities, especially in the case of São Paulo, where houses from the late 1800´s and early 1900´s are flanked by high rise apartment buildings. In order to develop and test the proposed method, a study will be carried out in a small Brazilian town called Monte Alegre do Sul. The town was chosen because its original urban morphology, developed in the XIXth century, is still relatively well preserved, although part of the original façades have been transformed. The objective of the research is to develop a shape grammar to set guidelines for the re-adaptation of the already renovated façades and reconstruction of other ones in Monte Alegre do Sul.

title Shaping the Global City: The Digital Culture of Markets, Norbert Wiener and the Musings of Archigram
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 301-308
summary The contemporary “built environment” as conceived by designers – be it actual or virtual; be it architecture, landscape, industrial products or, more purely, art – is increasingly generated using powerful computational tools that are shaping the culture of the design professions, so much so that the phrase “digital culture” aptly applies. Designers are rightly inclined to believe that the emerging contemporary landscape – especially in thriving global cities like New York, London and Tokyo – has recently been and will continue to be shaped in important ways by digital design. That will surely be the case. However, design does not exist in a material vacuum. Someone pays for it. This essay argues that the primary shaper of global cities today is another “digital culture”, one defined by the confluence of professions and institutions that constitute our global financial markets. The essay explores the common origins of these two cultures – design and finance; the prescient insights of Archigram into the cybernetic future of cities; the spatial implications of nomadic “digitized” capital and the hazards of desensitizing – in many ways, dematerializing – the professional practices of design and finance. The purpose of the essay is not to establish primacy of one over the other. Especially in the case of urban design, they are interdependent. The purpose is to explore the connection.

title Time in Adaptable Architecture - Deployable emergency intelligent membrane
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 249-258
summary The term "Parametricism" widespread mainly by Patrick Schumacher (Schumacher, 2008) is worthy of study. Developing the concept of Human Oriented Parametric Architecture, the need of implementing time as the lost parameter in current adaptive design techniques will be discussed. Morphogenetic processes ideas will be discussed through the principle of an adaptable membrane as a case study. A model implementing a unique Arduino[i] on the façade will control its patterns performance through an Artificial Neural Network that will understand the kind of scenario the building is in, activating a Genetic Algorithm that will optimize the insulation performance of the ETFE pillows. The system will work with a global behavior for façade pattern performance and with a local one for each pillow, giving the option of individual sun-shading control. Machine learning implementation will give the façade the possibility to learn from the efficacy of its decisions through time, eliminating the need of a general on-off behavior.

title A survey of computer software for the urban designprocess

summary Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

summary Since Hugh Ferris in 1922 started with a series of massing studies the visualization of zoning planning began to be a topic for architects. Setbacks, plot area ratio, maximum building height, and other important attributes must be handled by the architect to fulfill the law, the needs of the clients and his own inspiration. This paper presents the problem of envelope design for high-rise isolated housing buildings, as well as a new Decision Support Systems tool based on the platform of a BIM software, that allows to simulate several options for building envelope according to the parameters required by the city Zoning Planning. These options deliver reliable data and geometry, to be analyzed in real time for the architects, engineers, builders, government and the client in the early stages of the building’s design.

summary The Urban Decision Room (UDR) should be placed in the tradition of urban design and planning discipline that is taught, and into which research is carried out, at the Faculty of Architecture at the Delft University of Technology. The UDR was developed at the faculty as one of the new design and planning methods with its own specific features. The UDR is specifically aimed at decision-making processes in the practice of urban planning, and particularly at complex urban area development projects. The background to the design enables the UDR to support planning decisions that are made at urban planning element level. The participants in the interactive UDR sessions are asked to provide concrete solutions for urban planning design problems (in terms of preferences for particular functions, number of plots, etc.) and to enter them in a simulation model. A computer network is then used to calculate the common solution space of all the proposals, which is then projected onto a central screen. This outcome generally provides the basis for further discussions and negotiations, after which another round as described above can be held. The paper first focuses on the background and the main features of the UDR system. Secondly, the decision-making issue and a description of a specific Urban Decision Room model, the UDR Heijsehaven will be explained. Thirdly the structure of, and the experiences from, the experimental sessions with the Urban Decision Room Heijsehaven are described. After that the results of the evaluation of the UDR system by participants is presented and finally the follow-up assignment for the UDR system is carried out.

summary The Hydrauli_city project was commissioned by the Harris County Flood Control District, Brays Bayou Partnership and the Rice School of Architecture to research the transformation of one of the 21 main Bayous in Houston. The project seems perfectly aligned with the theme of the issue because it examines the relationship between infrastructure, risk and urban design, and does so by attempting to leverage diverse time scales and scales of intervention into the maintenance of this infrastructure, rethinking the legacy of its top-down 20th century planning logics. Moreover, it raises key questions about new agencies and sites that may be available to architects that seek to engage the political ecologies of the contemporary metropolis. Through research on the hydraulic urbanism of Houston and through three speculative design proposals, Hydrauli_city presents research about transforming Brays Bayou. The project attempts to provide a figure for and foster the new forms of collectives and networks required to transform the urban condition of Houston without resorting to unrealistic top-down planning infrastructures. We located several scales and time-frames of operations, from micro-scaled interventions derived from ongoing maintenance of the bayous to larger scale transformations now possible due to the programs to reduce the risk of flooding in the bayou’s watershed. Hydrauli_city maps the confluences of interests and agencies invested in Brays Bayou at this crucial moment in its history, and offers proposals of bold new civic spaces for the Green Century. The project will be disseminated via an interactive website and a series of public presentations to raise awareness and spark conversation. Flood risk management is a hybrid phenomenon, at once the object of scientific knowledge, engineering practice, and political and economic forces, positioning the architect in a prime-position to intervene.

summary New boroughs are continuously being built in Brasilia, Brazil’s Capital City. The paper deals with the performance of such boroughs concerning sociospatial segregation. A comparison is made between two proposals for a new borough to the West of the North Wing of the Pilot Plan, which was originally designed by Lucio Costa. The first proposal was made by a wellknown architectural studio in Brasilia and is beginning to be implemented. The second proposal is an exercise made by undergraduate students from the School of Architecture of the University of Brasilia, under the supervision of one the authors of the paper. The two proposals present very different performances. In the first case, the borough is set apart from the immediate urban surroundings; there is no direct connection between inner roads and the main arteries that surround the site. In the second case, the students have proposed a scheme that connects the interior areas of the borough to the vicinity; we hardly know where the new borough begins vis-à-vis the neighbouring areas. We argue that there are serious traffic implications in the first case, as well as sociological implications. We deal with traffic modelling, space syntax techniques and geoprocessing tools to prove so. Furthermore, we will show how the building types are as well socially inadequate, for they will imply homogeneous social layers among the inhabitants – namely exclusively high-middle class living in the new area.

title Modelling urban dynamics through cellular automata: an empirical application

summary Actual developments of digital maps and tools given by GIS-systems provide the possibility to develop new methodologies to handle land-cover data for modelling purposes. At any rate empirical applications are still rare within the Geosimulation studies and yet there is not an established methodology. The aim of the work has been to construct a cellular automata (CA) model of a sprawling city region within the German context, based on empirical data. The urban land-use classes (LUC) are considered as a higher organisation level of different building typologies and relative functions. These define the land-use patterns as self-organized from their complex spatial iterations, based on limited local information exchange. On the one hand the synthesis capacity of the CA models has been verified, even without socio-economical variables. On the other hand, it has been seen that the still early evolutional state of digital land-cover datasets are too premature to fully suite the modelling purposes.

title Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title Analyzing Pedestrian Movement in Mataf Using GPSand GIS to Support Space Redesign

summary Evaluating the use of architectural and urban spaces is an important issue for architects and urban designers who wish to enhance space usability. Space usability is crucial in crowded spaces such as Mataf areas. Millions of people come to the city of Makkah, Saudi Arabia every year to perform Hajj (Islamic Pilgrimage) and Umrah. A cornerstone of Hajj and Umrah spirituals is to perform Tawaf, which is the circumambulation of the Ka'bah in the center of the Holy Mosque in Makkah. The areas of performing Tawaf (called Mataf) become very crowded during Hajj and the last ten days of Ramadan. This paper demonstrates how we utilized Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to analyze pedestrian movement while performing Tawaf. During the Hajj of 1424 H (2004 in the Georgian Calendar), several GPS devices were used to collect pedestrian movement coordinates at specific time intervals. Computer software for tracking analysis is used to visualize and analyze the pattern of pedestrian movement in Tawaf. The software allows users to view temporal data, which can be set up with past time windows for historical data analysis. The findings of this research show levels of service and flow rates throughout different zones and times of Mataf. They indicate the most critical zones and times for Tawaf during Hajj. They also visually demonstrate the track pattern of pedestrian movement at different locations in the Tawaf area. The paper concludes with some redesign recommendations to remove obstacles and facilitate pedestrian movement in Tawaf. The approach described in this paper can be implemented in architectural and urban design space modifications to improve pedestrian movement in open spaces.

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.

summary In this paper, we present a new multi-objective location model for urban parks and open spaces (POSs) planning. We developed a Genetic Algorithm (GA) based multi-objective optimization model (GAMOOM) to derive optimum locations of POSs by considering four incommensurable objectives with the provision of POSs near: 1) densely populated areas, 2) air polluted areas, 3) noisy areas, and 4) areas without open spaces. The success of the model is presented through its application as a case study on Dhaka City. Obtained results indicate that the model can successfully provide optimum location of required POSs. The findings from this study also signify that optimum location of POSs obtained by utilizing only the second objective is substantially different than that of others. Moreover, there is also difference in optimum location of POSs by taking into account only the third objective when compared with others. Therefore, considering single objective cannot give optimum results for good POSs planning. So, it is verified that POSs should be planned by optimizing multiple objectives instead of single objective. The outcome of this multi-objective GAMOOM model does have an implication on how POSs should be designed and managed by the planning authority for not only sustainable environment but also better quality of life in a city.

title Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

summary This paper presents the work that conduced to the development of an information system to evaluate and monitor university campi quality of life. The system embodies two main functions: to provide information to the community and to support campus planning and management. Using a scenario describing possible actions, some users evaluated how its implementation would interfere with the quality of life on the campus. Results showed that it would produce a global improvement, in comparison to the year of the study.

summary Driven by advances in building and information technology and accelerated by the tumultuous period of global economic restructuring that commenced in 2008, architecture and interior design practice is today confronted with the necessity of fundamental change. According to the “Building Futures” group at the Royal Institute of British Architects and US-based “Design Futures Council,” both of which this past year published studies on this very topic, a great deal depends on what happens in China and other emerging markets, where many European and US firms now have offices. And that is not only because these are the most vibrant markets for architecture and design services, but also because the demands placed on practitioners in these markets are fundamentally changing the way buildings are designed and delivered, at home and abroad. Both studies suggest that all sectors of the A/E/C industry will face increasingly fierce competition that will, of necessity, force practices large and small to compete less on cost and more on value. In the very near future buildings and their interiors will be valued almost entirely based on performance—economic, cultural, environmental—and only those firms able to create these and other forms of added value will survive. Disruptive technologies like building information modeling and integrated product delivery will enable all firms, even those competing solely on the basis of cost, to design better buildings and deliver them more efficiently. But in such a fiercely competitive global marketplace, efficiency alone will not be enough to guarantee market viability. The real differentiator will instead be design.

summary New information and communication technologies (ICT’s), gain importance and are changing people’s daily lives. With the introduction of new ICT’s, alternatives for face-to-face contacts and physical presence are provided. In that sense, ICT may offer a substitute to physical travel. Other potential relationships between telecommunication and travel are neutrality, complementation or modification. The relationship between ICT and activitytravel patterns has received a substantial amount of attention recently. However, a link with the wider activity patterns of individuals and households and environmental characteristics is missing in existing studies. The spatial and mobility impacts of social networks are not well known either. However, social networks are crucial to an understanding of travel behaviour. The most important part of travel demand for non-work purposes in terms of distance travelled is for socializing with network members. Hence, individuals’ social network characteristics are relevant for their propensity to perform social activities. The study of social networks can provide new insights to understand the generation of social activities and travel involved. In order to increase our understanding of the interrelationships between properties of the built environment, ICT-use, social networks and activity-travel patterns, these links should be the starting point for analysis. This paper presents a data collection instrument that was developed to study these links and the results of an application of the instrument in a survey among a large sample of households in the Eindhoven region, and discusses the implications of the findings for planning support models.

summary Through the use of existing digital tools, the research work consists of proposing a new 3D navigation mode based on systemic, practical and graphic assumptions. During the exploration of the Vianden Castle, we outline a graphic representation system as an aid to representation and memorization of archaeological and architectural knowledge. For this, we recompose some concepts related to video games, we materialize the “mental map” described by Patricia Marks Greenfield and we take into account the cognitive capacities of the learner.
