title	Rapid Craft: Material Experiments towards an Integrated Sensing Skin System
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 182-191

summary	The distinction between matter (mechanics) and information (electronics) in the context of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in applications of remote sensing after the process of material fabrication. Sensors are commonly perceived as electronic patches which initiate mechanical output with response to electrical input. This work seeks to establish a novel approach to the application of electronics in building skins, which prioritizes material selection, behavior, and fabrication technology in relation to the required task, over postproduction sensor integration. The term “Rapid Craft” is proposed to describe such design protocols which couple material behavior and fabrication in the design of responsive skins. Rapid Craft is a designation for the incorporation of craft materialization knowledge within the framework of CNC processes of fabrication. A light-sensing inflatable skin system is developed as a working prototype, which demonstrates such an approach.

summary	In the last decade Computational Building Performance Simulation (CBPS) has acquired the reputation of a solid analytical method. However, this reputation relies mostly on the admittedly advanced and robust theoretical and algorithmic basis of performance simulation techniques. On the practical side, building simulation has yet to live up to expectation. The main reason is that simulation use is not as widespread as it should. Applications are mostly academic, mainly validation studies. This has led us to the assumption that the applicability and usability of performance simulations require additional components that link them more closely to design processes and facilitate their integration in everyday design activities. In this paper we present the results of research into a working method for location-specific daylight simulation. Our method is based on the satisfication of a number of requirements common to many types of CBPS: validated simulation algorithms, flexible, fast calibration by means of real-world measurement, multiyear, location-specific environmental data, and support of both measured and mathematical environmental data models.

title	Developing a New Approach of Computer Use ‘KISS Modeling’ for Design-Ideas Alternatives of Form Massing: A framework for three-Dimensional Shape Recognition in Initial Design Phases
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. 745-756
summary	This research aims at developing a new approach called ‘KISS Modeling’. KISS is generally a rule of ‘Keep It Simple, Stupid’ that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ‘KISS Modeling’ that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research, however, does not employ totally concepts of shape recognition or shape understanding in Artificial Intelligence and psychology. The research, in summary, investigates and describes: 1) a new approach of computer use contributing to generating design-ideas alternatives of form massing in initial design phases, within a simple way that any designer can understand at single glance, 2) implementation of shape recognition for generative three dimensional forms, 3) function to generate different outputs from different recognition, and 4) case studies introduced through applications and functions of the three dimensional modeling system presented by the research. The research concluded that the introduced processes help the user improve the management of conceptual designing through facilitating a discourse of his/her modeling of design-ideas massing.

title	Structuring a Generative Model for Urban Design: Linking GIS to Shape Grammars
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 929-938
doi	https://doi.org/10.52842/conf.ecaade.2008.929
summary	Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

title	Multi-touch - the future of design interaction
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. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	DVIN: A Dual View Information Navigation System
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 104-109
doi	https://doi.org/10.52842/conf.acadia.2007.104
summary	Differences in the preferred modes of representation of architects and their clients create challenges to their collaboration in the design process. Traditional two-dimensional drawings such as plans, sections and elevations form the backbone of architectural representation, anchoring text labels to record relevant non-graphical information. Nominally geometric “slices” through the proposed building volume, these drawings employ abstractions and conventions unique to professional practice. In contrast, non-architects think about building configuration largely through experiential or photographic perspective. This challenge increases over the life of the project. Simple drawings, such as those used in schematic design, are easily understood by all parties. However, as the building design develops the architects encode more and more design detail through the drawing conventions of construction documents, inadvertently making this detail less and less accessible to non-architects. We present DVIN, a prototype system that uses coordinated plan and perspective views for navigation of building information models, linking the information to an individual’s spatial navigation skills rather than their document navigation skills. This web-based application was developed using Java and VRML. The prototype makes it easier for naive users to locate and query building information, whether they are a client, a facility manager, or possibly an emergency responder. * NOTE: two pages missing from the printed proceedings have been appended to the PDF version of this paper and numbered 'erratum page 1' and 'erratum page 2' *

title	Detailed 3D Modelling of Castles
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 200-220
summary	Digitally documenting complex heritage sites such as castles is a desirable yet difficult task with no established framework. Although 3D digitizing and modelling with laser scanners, Photogrammetry, and computer aided architectural design (CAAD) are maturing, each alone is inadequate to model an entire castle in details. We present a sequential approach that combines multiple techniques, each where best suited, to capture and model the fine geometric detail of castles. We provide new contributions in several areas: an effective workflow for castle 3D modelling, increasing the level of automation and the seamless integration of models created independently from different data sets. We tested the approach on various castles in Northern Italy and the results demonstrated that it is effective, accurate, and creates highly detailed models suitable for interactive visualization. It is also equally applicable to other types of large complex architectures.

title	A Spatial Information System for the Archaeological Site of Mycenae
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 376-394
summary	Digital and automated photogrammetric procedures, developed for the collection and management of spatial data, and terrestrial laser scanning systems provide new capabilities for documentation of archaeological monuments and sites. Also, special tools in Spatial Information Systems and production of virtual models have been developed. Their combination provides relevant scientists (architects, archaeologists, etc) and users with a variety of options for the creation of integrated systems capable for documentation, restoration and cultural development of archaeological sites. Detailed 2D and 3D representation of the current condition of the site, development of a multi-purpose SIS, and introduction of modern digital products at a local museum, such as 3D models, creation of virtual environment and Web applications are some of them. Application of such techniques and systems was made to the archaeological site of the Mycenae in Greece, one of the most important sites worldwide.

title	Collaborative Knowledge Construction in Digital Free-Form Design
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 735-742
doi	https://doi.org/10.52842/conf.ecaade.2007.735
summary	This paper focuses on the emerging domain of digital free-form design, and attempts to explicate its knowledge content and characteristics through a systematic inquiry of the digital free-form design practice. The massive amount of information associated with the design and construction demands of the complexly shaped buildings demand explicit knowledge about the way various information pieces relate to one another. This paper reports on the process of developing a knowledge framework which serves as a reference model to describe and explain the free-form design and production processes in terms of the interaction of contextual conditions and according to the different ways design problems are perceived and formulated by the members of the design teams. The framework provides guidelines for the development of a web-based design decision support system to support collaborative knowledge construction, sharing and reuse in the domain.

title	Fuzzy Modelling for Early Architectural Design
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 589-610
summary	Fuzzy modelling is simultaneously an extension of existing modelling approaches and a negation of one of their main aspects, the crispness of their definition. As a digital equivalent of analogue sketching it allows designers to register and manipulate imprecise and uncertain information. In the framework of design representations fuzzy modelling supports the development of conceptual design models characterized by flexible definition and interaction. The main advantages of such models are fluency, abstraction and continuity, at a level similar to that of analogue techniques. In addition to that they offer the possibility of local autonomy, i.e. segmentation of a representation into self-regulating and cooperating components. Three alternative forms of fuzzy modelling are proposed: (1) Canonical objects with tolerances, (2) objects described by minimal and maximal values, and (3) point sets comprising discrete, autonomous particles that describe the object by their spatial or structural relationships.

doi	https://doi.org/10.52842/conf.ecaade.2007.311
summary	The existent and idle stock of buildings is extensive. However, significant information about these buildings is hardly available. The real estate owners are usually not known by prospective customers and they can be elicited only with substantial effort. But even if data about a building is available, it is difficult to valuate it precisely, because there are no standard classification techniques available, which would also consider the subjective subsequent requirements of the interested parties. The question whether a building is suitable for a certain subsequent use is therefore hard to answer. It involves an extensive expenditure of time and manpower. No reliable statement about a prospective reuse of a building can be made on site by prospective clients, i.e. buyers or renters. Therefore, we examined the technology needed by the customer to accomplish in-situ ad-hoc analyses of existing buildings. These technologies are namely remote sensing devices using georeferenced data, Location-Based Services and web-based optimization techniques. The aim is to give prospective clients the possibility to visit a building and run an in-situ usability simulation. To accomplish this, building information will be transferred between the building and the client through the use of common communication devices. These devices automatically connect to server-based applications, which compare the requirements of the prospective customer with the existing building and run remote simulations on concrete further utilization. By the use of georeferenced data alternative locations of unused buildings can be integrated into the simulation as well.

doi	https://doi.org/10.52842/conf.ecaade.2007.785
summary	The distinction between material behavior (mechanics) and material response (electronics) in the framework of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in the implementation of remote sensing devices post the process of material fabrication. Sensors are commonly perceived as electronic add-on patches which initiate mechanical output with response to electrical input. This work seeks to establish a novel approach to the integration of electronics in building skins which prioritizes material selection, behavior and fabrication given a required task, over post-production sensor application. The term “FAB Finding” is proposed to describe an instrumental methodology facilitating the coupling of CNC fabrication processes with material organization and behavior. It offers a design mentality which emphasizes the nature and the effects brought about by the use of specific fabrication processes which are by definition inherent in the design product and its behavior. A light-sensing inflatable skin system is developed as a working prototype demonstrating such an approach.

summary	In the era of communication, the participation in internet-communities has grown to become a motor for innovation in software and community platforms. The paper describes the hypothesis that, by creating a virtual city (or a second city) a new type of social, economic and scientific network is established, which is supported through visual communication technologies. The various users bring, per se, their own intrinsic motivation and requirements to the system. Nonetheless, a personal identification with a city/neighbourhood/house/apartment can be used to awake awareness and to foster participation. This is especially important when dealing with the city inhabitants. City modelling itself has been carried out for over a decade. Projects such as the city model of Graz have shown how city models can be established so as to be scalable for new information (Dokonal et al 2000). Furthermore, these city models have been used in the education of future architects and urban planners. The project described here moves in the opposite direction: the model moves out of the classroom to an interdisciplinary city-model-platform. The work described here is the conceptual model for a multi-dimensional data set that models the city. This has spawned a host of other projects using the model as a foundation for further interactivity development and the extension of the model itself. The paper describes the structure of the conceptual model and the first experience of incorporating diverse projects such those mentioned above. The model also is structured so as to be compatible with the XML standards being developed for city information (CityGML). The goal of the project is to create a data set describing the city that not only describes the geometry, but also the history (including planned histories) and nature of the city. In contrast to virtual realities, which attempt to create a separate world (e.g. Second Life), the Second City is intended as an interdisciplinary repository for the geometrical, historical and cultural information of the city.

title	242 On the Strategic Integration of Sketching And Parametric Modeling in Conceptual Design
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 242-249
doi	https://doi.org/10.52842/conf.acadia.2007.242
summary	Architects perform problem-solving tasks while designing through various externalization modes. Among the architectural community sketching is associated with conceptual design, and parametric modeling is seen as a tool for detailed design development. However, parametric modeling is increasingly being used for exploring design concepts. We propose that sketching and parametric modeling can be integrated strategically as alternate externalization modes to support problem solving in conceptual design. With sketching, architects are able to externalize their ideas quickly and effortlessly, as the flexible structure of sketching provokes multiple interpretations through continuous refl ection. With parametric modeling, architects must define a set of parameters and rule-based constraints. By modeling design objects as parametric, multiple design variations can be generated, modifi ed, and evaluated. In this paper we describe an efficient process of problem-solving by studying the strategic use of sketching and parametric modeling in conceptual design. We conduct an experiment to explore the processes involved in both modes. Digital sketching is recorded by the Logitech io2 personal digital pen, and parametric modeling using Digital Project software is recorded by screen video capturing software, followed by a retrospective analysis. The ACADIA 2007 competition brief is used as the design task.

title	Multimodal Mixed Reality Interfaces for Visualizing Digital Heritage
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 322-337
summary	We have developed several digital heritage interfaces that utilize Web3D, virtual and augmented reality technologies for visualizing digital heritage in an interactive manner through the use of several different input devices. We propose in this paper an integration of these technologies to provide a novel multimodal mixed reality interface that facilitates the implementation of more interesting digital heritage exhibitions. With such exhibitions participants can switch dynamically between virtual web-based environments to indoor augmented reality environments as well as make use of various multimodal interaction techniques to better explore heritage information in the virtual museum. The museum visitor can potentially experience their digital heritage in the physical sense in the museum, then explore further through the web, visualize this heritage in the round (3D on the web), take that 3D artifact into the augmented reality domain (the real world) and explore it further using various multimodal interfaces.

title	Ubiquitous Training of Visual-Spatial Skills: On the Development of Mobile Applications Using Handheld Devices

doi	https://doi.org/10.52842/conf.acadia.2007.146
summary	This research project seeks to develop m-learning applications that provide training in visual-spatial skills using wireless handheld mobile devices (e.g. PDAs and cellular phones). The paper acknowledges the role of visual-spatial competence as fundamental in science and most creative endeavors, including its critical role in architectural design. It also recognizes that there is a substantial amount of anecdotal evidence suggesting that undergraduate students in architecture have serious limitations in applying visual-spatial skills for design activities. A potential solution to this problem is envisioned through the introduction of extra-curricular learning activities that are ubiquitous and learner-centered. The suggested m-learning applications will include a set of instructional modules making use of media-rich representations (graphics and animations) for conveying the nature of 3-D spaces. As a first step toward reaching this development, a prototype was created and used for testing learning strategies. This experiment provided evidence regarding improvements to specific aspects of the students’ visual-spatial competency, and it also collected qualitative feedback regarding the students’ level of satisfaction about the learning experience. The paper provides recommendations for a future implementation of the beta version, including the learning strategy, content authoring, publishing, deployment, and criteria for the selection of the most accessible mobile device.

These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

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.
