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	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title	goBIM: BIM Review for the iPhone
source	ACADIA 09: reForm( ) - Building a Better Tomorrow [Proceedings of the 29th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-9842705-0-7] Chicago (Illinois) 22-25 October, 2009), pp. 273-277
doi	https://doi.org/10.52842/conf.acadia.2009.273
summary	This paper summarizes the development of goBIM, a model viewer, markup, and data-querying environment that utilizes Apple’s iPhone and Autodesk’s Revit software. Geometric and database information are written to a user defined server location via a custom Revit plugin. Model geometry and database information are loaded at run-time from the web server to the goBIM iPhone application, using a cellular network connection or WiFi. The user can then navigate the 3D environment, selecting objects to view their associated database information. The user has the ability to tag elements in the model with additional data, which can then be pushed back to the server and reloaded in the local version of the Revit model. BIM data can now be accessed anywhere there is a WiFi or cellular network connection available.

title	Información interconectada, curación colectiva y experiencias de usuario: El caso de la red social Pinterest [Interconnected information, collective curation and user experiences: the case of Pinterest social network]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 167-170
summary	We present exploratory studies about 2.0 web applications linked to renewed collective curatorial activities. In particular we focus on Pinterest application, which collectively generates collection spaces centered in a strong both image and digital graphic presence. We analyze practices related to User Experience Design, which refer to all the factors linked to Interface Design, and produce positive or negative perception of the application. We use the Shedroff model (2009) exploring dimensional categories about significance, duration, amplitude, intensity, interaction and triggers or experience releasers.

title	Emergent space diagrams: The application of swarm intelligence to the problem of automatic plan generation
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 245-258
summary	This work investigates how diagrams of architectural space might self-organize relative to specific associational parameters to generate diagrams of spatial organization. The premise is that buildings are systems of spatial relations defined by the dynamic interactions of various autonomous spatially discrete entities. Looking to swarm intelligence, the focus here is on the problem of circulation and explicit spatial arrangement. The paper reports an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction. An array of ant colonies defines the system. A colony’s nest represents a specific space. Space-agents transmit information throughout the space-colony population, defining an emergent communication network.

title	Ativação da Memória para O Projeto de Arquitetura através de Metadados para a Caracterização da Forma [Activation of Memory for the Project of Architecture through Metadata for the Characterization of Shape]"
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Geometric knowledge increases the memory of the architect, which is formed dynamically, from new experiences on the comprehension of shape. Such process suggests the acquisition of a specific vocabulary for describing shape. With the aim of recognizing a wide geometrical and architectural terminology, experimentation is performed. The present work also describes an architectural project which uses metadata characterized by the identification of knowledge structures composed of four approaches whose geometrical and architectonical focus are present. The proposed systematization, which denotes and delimits a specific vocabulary, is considered as being able to contribute to the re-indexing of formal frameworks through the dynamic process of memory constitution to the architecture design.

title	Interactive Hemostasis Modeling in Urban Network Design
source	International Journal of Architectural Computing vol. 7 - no. 3,375-387
summary	This paper describes a type of project that images a city as it might exist given the integration of hemostatic procedures within pedestrian networks during emergencies requiring full-scale egress from an urban core. It articulates the steps taken to integrate a pre-existing C++ hemostasis model (C. Jacob, 2008) into Maya software in order to describe how the project operates on a computational level. By projecting these agent-based logics directly into/onto each pedestrian in the city (the smallest unit of the system), egress-oriented infrastructure can shift from being extensively predetermined in form (concrete barriers, metal railing, police barricades, etc.), to something more intensively defined, real-time, and locally on-demand. These procedures are situated within a larger schema based on the structural principles of Norbert Wiener's cybernetic feedback loops, that acknowledge and allow for hybrid (top-down + bottom-up) awareness and control within systems. The project attempts to ally itself with emerging forms of network design with similar structural typologies supported through the use of personal mobile devices (PMDs) in urban environments.

title	A influência do usuário sobre a apresentação visual da informação na web: o caso do layout adaptativo e da personalização de layout [User's influence on the visual presentation of information on the web: the case of adaptive layout and layout’s customization]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Ahead of the digital environments expansion which follows the principles of the web 2.0, one can notice a growing opening for user's participation. The proposal of this research is to reflect on how this scenario of participation is strengthening a social structure capable of actively acting not only in the production of digital content, but also in the form of this content presentation. From a survey of cases and a theoretical review, this paper aims to analyze two different types of user’s influence on the visual dimension of web environments. One first - adaptive layout - based on the indirect user’s action and a second - layout’s customization - based on the direct user’s action.

title	Fotografia digital e imagens multi-perspectivas no estudo de sítios históricos [Digital photography and multi-perspective image in the study of historical sities]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The creation of panoramic images for depicting urban landscape is a technique that has its origins in Antiquity. These images, which are known to represent large urban areas from multiple views, can be considered true works of art. Recently there has been a growing interest by some researchers, especially in the area of computer graphics, in the production of multi-perspective images for representing historic sites. However, the focus of these studies has been especially the computational aspects of this process, and there are few studies that address the impact and possibilities of these methodologies in historic preservation and urban planning. Realizing this shortcoming and considering the demand for a perspective more connected to cultural heritage, our proposal is to associate the excellent visual results of the multi-perspective images to the rich possibilities of computer simulation that can provide digital photography. The fact is that in recent years we have experienced technological innovations in the field of computer simulation that far exceeded our expectations. While most surveys of buildings are still based on the use of tape measure, pencil, paper and camera, the computer has become increasingly the main interface between the user and the information and is now the preferred instrument for the production and viewing of images, including the creation of virtual environments. Thus, this work seeks to explore the great potential which seems to exist in the combination of digital photography and the technique of multi-perspective image representation, which may provide new approaches and perspectives for the field of historic preservation. For that, we present a rapid and low cost methodology, developed in recent years, which generates orthophotos and metric multi-perspective images, useful for the analysis of built heritage and historic sites. In addition to that, we will also discuss further possible byproducts of this methodology, among which we could highlight the creation of three-dimensional models, and the analysis of building pathologies in combination with thermal photography. As a case study, we will present a representation of the Rua dos Caetés, a listed historic district in Belo Horizonte (MG), Brazil.

title	3D Collaborative Environments in Archaeology: Experiencing the Reconstruction of the Past
source	International Journal of Architectural Computing vol. 7 - no. 1, 57-76
summary	This paper presents the outcome of the research project: "Integrated Technologies of Robotics and Virtual Environments in Archaeology", financed by the Italian Ministry of the University and Scientific Research, FIRB (Funds for the Investments of Basic Research). The aim of the project is to experiment and realize a multi-user domain on the web aimed to a multidisciplinary scientific community: archaeologists, historians, experts in human and social sciences, communication experts. The capacity to load, share and interact with data in the same spatial virtual environment can increase the level of learning and scientific communication. The project is the result of the collaboration between CNR-ITABC of Rome, the University of California, Merced, the Department of Archaeology of the University of Pisa and Scuola S. Anna of Pisa. It focuses on three archaeological sites: the Teban tomb 14 in the necropolis of Gurna, Fayum Medinet Madi, both in Egypt, and Khor Rori, in Oman. The collaborative environment is constructed through a virtual reality system. This allows to create a virtual space where it is possible to share 3D information on the project and to host additional behaviors of the scientific community.

doi	https://doi.org/10.52842/conf.acadia.2009.278
summary	Widespread use by 3D designers of simple digital modeling applications such as Google’s SketchUp may displace the use of physical models in design. However, the difficulties often faced by non-experts in the ad hoc navigation of digital models during design reviews have not been eliminated. Keyboards and mice are clumsy navigational devices and difficult to share in a collaborative setting. This work explores the combination of new, inexpensive interface hardware technologies with a popular 3D modeler in order to create a viable surrogate for physical models. Two architectural model navigation and presentation interfaces were developed, one based on an Inertial Measurement Unit (IMU) circuit board (“Gizmo”), and one that used a Wii Remote Controller (“WiiView”). Both were interfaced with the popular architectural modeling program SketchUp. Anecdotal responses and preliminary user testing results are presented.

summary	A distinction is drawn between designing settings that are part of the performative framing of immediate behavior and, the often more difficult task, constructing an architecture of possibilities. Analogies are drawn to the work of stage magicians and software interface designers that suggests some attributes of both of the above aspects of architecture. The concept of “Utilitas” is explored both as a way of reducing variety so change can be introduced in an orderly manner and as a way of initiating a rich and complex user illusion

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	When technology moves forward, architecture changes with it: it changes the architecture methodology and it changes the architectural result. This paper discusses the variables involved, pointing the major constraints to the intensive use of ICT in the architectural process. It highlights the need to rethink the user’s involvement in the conception of the built environment, increasing it, and suggests new approaches to meet this need by using ICT and VR.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 557- 571
summary	Mobile devices have become widely used in outdoors on-the-move applications. Our research aims at developing a system which allows users to visualize the virtual buildings, streets, historic sites, landscapes or cityscapes (in the past or future) which are rendered seamlessly with the current actual scene captured by the camera (called Augmented Reality), and interactively exploring the virtual scene in real-time while the user is moving. We use the camera PDA, the GPS receiver and the gyroscope to track the mobile device’s position and orientation for virtual scene rendering. This article documents the issues regarding accurate alignment, tracking, errors and limitations with mobile devices and presents our solutions generated so far for the research in progress.

title	How do media influence one’s thinking? The “habit media” in design thinking
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 614- 625
summary	This paper presents a preliminary observation of the digital media as “habit media” in designing act. The digital media has become a costumed vehicle for designers for a long time. The author investigated the supports of different media for how a specific media conditioned the design thinking and the reasons behind the behaviors of choice-use of designers’ choice. The results showed that designers using “habit media” could do most part of things they wanted to do; when the media are “habit media”, its inherent restrictions do not limit user’s accomplishment. Once a digital medium is habitually practiced, it can support the functions and characteristics that this medium does not ever possess.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 705-714
doi	https://doi.org/10.52842/conf.caadria.2009.705
summary	This paper describes the design and implementation of TangiDESK, a tangible interface prototype to assist in the design and planning of urban design projects. The prototype derives from the need for an intuitive user interface similar to a designer’s or architect’s CAD system but also simple enough for non-designers like city planners and developers who are not accustomed to CAD interfaces to use and understand easily. Users can manipulate the objects or modify its relationship with other elements in the site while making preliminary design decisions together in a single environment. With TangiDESK, designers and planners can collaborate and make informative decisions more effectively and accurately in early stages of an urban design project.

doi	https://doi.org/10.52842/conf.caadria.2009.423
summary	InteractiveChair is proposed as a natural and affordable medium that enables direct control of locomotion in 3D virtual space by using dynamic sitting postures. InteractiveChair detects subtle movements of a chair occupant in real time by measuring relative position and orientation between the user’s body and the chair. While standard user interfaces require users to consciously relate the device manipulation by hand to the action in the virtual space, InteractiveChair directly leverages the correlation between our body and spatial conception to control the avatar’s locomotion. This study determines typical user behaviours on the chair and measures them through sensors that are exquisitely integrated with a typical swivel chair. The study then presents results from a user study to measure the qualitative factors of user experience in controlling virtual locomotion with InteractiveChair.

title	The Design of a Mobile Navigation System Based on QR Codes for Historic Buildings
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 103-112
doi	https://doi.org/10.52842/conf.caadria.2009.103
summary	Due to the rapid development of mobile and compact electronic devices such as PDAs and smart phones, designers and developers now have to consider user mobility and the dynamic context of use in the design of interactive systems. In this study, literatures associated with mobile navigation systems in museums and historic buildings are first reviewed in order to understand the features, advantages, and drawbacks of current mobile navigation technology. The feasibility of applying QR codes in the navigation of historic buildings is then discussed, and the mobile navigation principles mentioned in previous literatures are applied in our proposed system. A number of common problems are encountered in the navigation of local historic buildings or museums. Visitors (1) cannot understand what makes an exhibited item a work of art; (2) do not know where to start or how to get started; (3) feel rushed by guides during the guided tour; and (4) find that the audio guide is not clear enough. Managers of historic buildings or museums are generally concerned about (1) the high cost of constructing a mobile navigation environment; (2) possible damage to devices; and (3) the cost of device maintenance. This study attempts to solve the above issues by constructing an affordable digital navigation environment that enables users to clearly understand each exhibited item and its location.

summary	The Old Library of Trinity College Dublin, built in 1732, is an internationally renowned research library. In recent decades it has also become a major tourist attraction in Dublin, with the display of the Book of Kells within the Old Library now drawing over half a million visitors per year. The Preservation and Conservation Department of the Library has raised concerns about the impact of the environment on the collection. The location of the building in the city centre, large visitor numbers, and the conditions within the building are putting the collection at risk. In developing a strategic plan to find solutions to these problems, the department has been assessing and documenting the current situation. This paper introduces ongoing work on a system to visualise the collected data, which includes: dust levels and dispersion, internal and external temperature and relative humidity levels, and visitor numbers in the Old Library. We are developing a user interface for which the data, originally stored in various file formats, is consolidated in a database which can be explored using a 3D virtual reconstruction of the Old Library. With this novel technique, it is also possible to compare and assess the relationships between the various datasets in context.
