title	Augmented Reality in Architecture and Design: Potentials and Challenges for Application
source	International Journal of Architectural Computing vol. 7 - no. 2, 309-326
summary	Recent advances in computer interface and hardware power have fostered Augmented Reality (AR) prototypes for various architecture and design applications. More intuitive visualization platforms are necessary for efficient use of digital information nowadays in the architecture and design industries. As a promising visualization platform to address this need, this paper introduces the concept and associated enabling technologies of AR and also presents a survey of its existing applications in the area of architecture and design. Another focus of the paper is to discuss how the identified key technical issues could potentially be addressed in the context of architecture and design applications.

title	Teaching Systems-Thinking with Algorithmic Process: Introduction to computation and programming with processing programming language
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 37-46
summary	This research investigates how algorithm design and scripting as pedagogy can affect generalized design ability and understanding. Logical, systematic thinking is considered foundational in developing architectural design aptitude and is explicit when designing algorithms. The course work presented mandates the construction of process rather than product. Scripting is implemented not as a means to an end but rather a medium for exploration. More valuable than formal generator or problem-solver, these scripted designs test direct aesthetic implications. Further tested is the role of animation in de-linearizing the design process. By isolating the algorithm as topic, technique, and concept, scripting skills and the produced artifact are extendable and are translatable to other media. Algorithm design is presented as a 2-dimensional but temporal endeavor: students script an animate, interactive vector-based image. This facilitates the transition from algorithm to spatial experience while also readying students for form-based explorations. The 2-d temporal exercise is of a similar order of complexity to a 3-dimensional static condition. Pieces of the animation structure are provided as a canvas, specifically the ability of the viewer to manually control a single parametric variable that affects the visual output through a user-interface element. The following and final project of the course expands upon the technique of scripting image in the design of an experience by collaging video, images and animation.

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	A Virtual Design Platform: Bridging Barriers When Designing with Computers
doi	https://doi.org/10.52842/conf.ecaade.2009.205
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 205-212
summary	The paper summarizes the results of a diploma thesis. Taking the potential of computers to be an ultimate design-medium as its premise, the thesis examines how to enhance the way we use digital design tools. It identifies central characteristics of the design process that need to be considered in a digital design environment. Based on a conception of design as a cyclic process involving appropriate design tools, the paper singles out usability, in the sense of ease of use of such tools, as a key criteria for overcoming problems associated with designing on and with the computer. Drawing on these considerations a prototype has been developed which attempts to bridge barriers between the use of different design tools using an existing software framework.

title	Optimal Organization of Architectural Spaces Based on Genetic Algorithm
doi	https://doi.org/10.52842/conf.caadria.2009.653
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 653-661
summary	Genetic algorithms categorized as global search heuristics are search technique of seeking approximate or exact solutions for optimizing problems. Our generative tool named notchSpace starts from a population of randomly generated individuals which rationally subdivide architectural spaces with a low “fitness”. During generations’ evolution, the population is recombined, modified and mutated at a low rate to form new modes of building spatial subdivision; a new population is used in the next iteration. NotchSpace works up a research platform to evolve architectural spaces, and it explores the thinking of translation from computer algorithms to the field of architecture.

title	Scripting Animation
doi	https://doi.org/10.52842/conf.caadria.2009.747
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 747-754
summary	Relationships are amplified and collapsed together as animate surfaces in the formal and spatial manifestation of design parameters. Animation is demonstrated as a medium to express topologies, as each frame is the resultant of a programmed serious of computations, the result of which varies with a parameter: effectively, time. Related conditions are parameterized through the design of algorithms as a means of direct translation into animation. Interrelated forces and limits can conversely congeal into statics with animate qualities. Process and product merge to create a language of phenomenological effects and patterns. While animation is exploited to represent parametric relationships there is a maintained awareness of time and space. The systemization and codification of design “problems” simultaneously facilitates functional, solution-driven architecture. The output is characterized by complex, performative, and specific solutions uniquely relevant to emerging models for fabrication and construction. Usage requirements and site conditions carry the weight of information-based contexts and experience-based symbols as fuel for the inherently cyclical process.

title	Material-Based Design Computation: Tiling Behavior
doi	https://doi.org/10.52842/conf.acadia.2009.122
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. 122-129
summary	From natural objects to man-made artifacts, tiling is all around us: it is the act of rationalizing highly complex form by breaking it up into smaller, continuous components. If well pursued, tiled objects can be easily designed and assembled. However, a geometric-centric view of tiling, whereby a predefined form determines the shape, size, and organization of tiles, has victimized the field of digital design. This paper questions the role of tiling as rationalizing method and offers an alternative theoretical framework and technical grounding for tiling behavior: the act of generation-through-tessellation informed by material behavior. The tools developed are implemented in the design of a 3D-printed chaise lounge, using multiple materials. The technical objective is to introduce a quantitative characterization and analysis of property mapping, as it is applied to a tiling algorithm using Voronoi cell tessellation. The network of tessellated Voronoi cells is used as an element in the Voronoi Finite Element Method (V-FEM) that the author developed. Various characterization functions and geometric parameters are generated, and V-FEM is executed for plane-strain analysis of doubly curved surfaces, from which global and local responses are evaluated.

title	Analysis and Evaluation on The Planning of Urban Open Space for Urban Disaster Prevention
doi	https://doi.org/10.52842/conf.caadria.2009.307
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 307-316
summary	Urban disaster prevention is an important aspect in evaluating the whole-function of a city. It is the most important and actual method to make full use of urban open space and to construct urban disaster prevention system in the work of preventing urban disasters. This paper presents an approach to solve the problem about the population evacuation during the earthquake, and a new method to spread out population data which can distribute the population in a district and locate to every house finally. At the core of the algorithm, the Wave-front Method is used to calculate service range of each open space. Urban planners can evaluate the layout of urban open space according to the distribution of population and traveling time predicted. Lastly, this paper provides some evaluating indexes for open space to integrate all open space units.

title	3D Model and Decision Support System for Fire Safety: A case study of Kingdom of Bahrain
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 419-430
summary	Fire agencies on all levels try hard to save lives, properties, and natural resources. Accurate access to critical information is essential in this regard, many agencies around the world have embraced GIS as a tool that helps them balance needs, uses, and hazards to promote sustainability of the environment while identifying and limiting vulnerability. At Kingdom of Bahrain, Ministry of interior established the Geographic Security System (GSS) to enhance the emergency response. The 3D of the GSS Consisted of 3 main parts: (1) 3D for terrain model, (2) 3D model for entire targeted zones, and (3) 3D models for individual buildings. In this paper, the integration between GSS system and 3D model will be illustrated, and how this kind of integration could enhance decision support system (DSS) for fire safety at kingdom of Bahrain. On other hand, we will highlight the technical and legislation difficulties faced in this project. Also, the future steps to enhance DSS will be discussed.

title	Assessment of a Physical Planning Project through Virtual Reality: A case study
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 365-378
summary	The study reports an application of VR models in the assessment of a part of physical planning project. The project outputs were different reports, GIS data and maps, and CAD drawings. The GIS data were used to create the VR models by importing Shpfiles of the GIS project outputs to VR software. The study presents VR models and the assessment of the physical planning project in terms of: 1) effect of the population increase, 2) effect of the required residential units, and 3) quality assurance for the current situation and future situation. The method used to build up the VR Models was through satellite images (by Google Earth Pro) and VR software (by UC Win/Road). Different models were built up to visualize and assess the alternative solutions and various influential factors. The study employed Virtual Reality in various urban and planning problems through models that are employed as tools of communication and design. The visualized environment and the associated models facilitated the evaluation of important areas, namely: impact of different factors and alternative solutions. The study concludes that the processes, such as decision making, visualization and representation, performed through VR manifest its importance to different design phases of urban and physical planning.

summary	CAAD is constantly provoking and raising many potentials, challenges and arguments in academia, practice, and even in the theory of architecture itself. This process starts with the pedagogy of designing and the ongoing questions such as how much of CAAD should be incorporated in teaching, and ends with digital design technologies and the new emerging questions such as how biologically inspired computational processes alter the form of our architecture and the typical design process. Architecture originates from peoples’ needs and beliefs. The new forms of digital architecture generate debates in terms of various important issues, ranging from emotional and social factors to sustainability and warming climate. The focus area of the conference can be shaped, as follows: considering all these potentials, challenges, and arguments, which we have to benefit from and cope with, are there truly legitimate concerns about the future of our architecture and its content in particular from human and environmental dimensions? Can we develop our own ways of benefiting from the technology that cater to our environment and culture? Can we still see the form of architecture in the traditional way or should we change our perspectives? In other words the conference concentrates on bridging between the new digital form and the traditional human content.

summary	Design considers function, fabrication, and aesthetics collectively. Computation is beginning to affect the competitive dynamics of design. Using algorithms, designers are exploring forms that are essentially “undrawable,” even with advanced modeling and direct manipulation techniques. Determining the appropriate functional characteristics may require the application of increasingly complex structural- and environmental-performance analysis techniques. To realize physically a design may require further geometric analysis and rationalization, and the use of complex computer-controlled fabrication techniques.

title	Creativity and Collaboration in Architecture Education in the UAE
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 245-256
summary	A review of national government literature indicates that today’s knowledge-driven economy demands a workforce equipped with complex skills and attitudes. Examples of these skills and attitudes are general problems solving, meta-cognitive skills, critical thinking and lifelong learning. Reviews of the Architecture, Engineering and Construction industry indicates a gap between architecture practice and education. The Egan report states that there is a need for a change of style, culture and process within the construction industry and it identified five driving forces, the report also recognised that the achievement of these driving forces is linked to training and education. Education must not only teach the necessary technical skills and knowledge, but also the culture of teamwork, collaborative work and creativity. The construction boom in the United Arab Emirates combined with the country’s mission to highly educate and train its nationals to be able to tackle market challenges provoked the necessity of implementing the culture of creativity and collaboration in education system. On the other hand, use of technology in education has been proven to facilitate and enhance the learning process. This paper will highlight the importance of implementing the virtual design studio as a technlogical platform in architecture education in the UAE in a way that aims to promote the culture of creativity and collaboration through the use of technology.

summary	ArtBus is a protocol and hardware bus for interfacing computers to sensors and actuators. It is a distributed interface, meaning that different parts of an ArtBus system can be at different locations in a space. ArtBus devices can be made on any embedded platform or microcontroller. While unconventional in some ways, ArtBus makes use of engineering design inspired by long established supervisory control and laboratory instrumentation practice. At the same time it is a simple, flexible interface which should be viable into the next generation of media devices and embedded control.

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 ‚Äúgingerbread houses‚Äù, 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.

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.

summary	A world of intense and quick changes has led the society to the Information and Knowledge Age. The use of information technologies leads to deep changes and new processes. Systems and organizations must be prepared for the growing amount and speed of information. The main objective of this work is the application of the computer simulation tools CAD/CAE to help decision-making in architecture and engineering projects, specifically metal structure projects. This work presents the application of the finite element method-based software Abaqus/CAE to analyze and propose possible project solutions to the case study of a metal structure which covers a food court in a shopping mall.
