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	Procedural Design of Urban Open Spaces

summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title	Developing an Interactive Architectural Meta-System for Contemporary Corporate Environments: An investigation into aspects of creating responsive spatial systems for corporate offices incorporating rule based computation techniques
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. 199-212
summary	The research paper exemplifies upon an attempt to create a co-evolving (socio-cultural and technological) programmable spatiality with a strong underpinning in the domain of computation, interaction design and open system typologies for the generation of a constantly informed self-adaptive corporate office space (which addresses the behavioral patterns/preferences of its occupants). Architectural substantiations for such corporate bodies embodying dynamic business eco-systems usually tend to be rather inert in essence and deem to remain closed systemic entities, adhering to a rather static spatial program in accordance with which they were initially conceptualized. The research initiative, rather than creating conventional inert structural shells (hard components), thus focuses upon the development of a meta-system, or in other words the creation of a ‘soft’ computationally enriched open systemic framework (informational) which interfaces with the ‘hard’, material component and the users of the architectural construct (corporate offices). This soft space/meta system serves as a platform for providing the users with a democratic framework, within which they can manifest their own programmatic (activity oriented) combinations in order to create self designed spatial alternatives. The otherwise static/inert hard architectural counterpart, enhanced with contemporary technology thus becomes a physical interface prone to real-time spatial/structural and ambient augmentation to optimally serve its users.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 253-256
summary	Architects have always wanted to visually simulate internal space before beginning construction. Visualizations through the use of synthetics images, static scenes or animations, are a powerful tool which can contribute to understanding and therefore improve architectural proposals for better environment comfort, and energy efficiency. Real time interactive visualization of changes proposed by the architect during the design is a valuable resource, particularly during the initial phases. However, this type of real-time interactive visualization requires considerable computing power, which places restraints and reduces interactivity.

title	The influence of Lighting on the Affective Qualities of a Virtual Theater
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 77-84

summary	In the development of 3D models of buildings, much time and effort is spent on enhancing lighting effects, to improve the perceived realism and quality of the models, and to create ambience. In an experimental setup, two versions of a 3D model of the Royal Carré Theater with different lighting conditions were presented to viewers, to assess the influence of lighting effects on their affective appraisals. A small group visited the real theater. The differences between the affective qualities of the models are smaller than expected, and participants seem to infer affective qualities and dimensions of an environment without paying attention to the specific lighting information. The affective qualities of the real theater show a correspondence to both versions.

title	Interactive Simulation in Virtual Environments - A Design Tool for Planners and Architects
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 116-126
summary	Simulations can assist planners in optimizing their design and in minimizing its environmental impact. By adjusting the architecture according to simulation results, and running further simulations based on the adjusted design, an iterative process can help to increase the design quality. Up to now computing simulations have taken a long time, thus only a very limited number of iterations could be calculated. This project shows an approach that is close to a real time simulation. By dividing the simulation into smaller parts and running the software on clusters or vector supercomputers, first results are available within several seconds, and reasonable results in less than one minute. Besides the technical features, another focus is the easy accessibility of the simulation. Intuitive methods like a tangible user interface provide easy interaction methods for specialists as well as non specialists. The results of the simulation can be visualized and interacted with from the desktop or any kind of virtual environments. Further aspects like limitations of automatic grid generation, shape recognition and computation power are discussed.

doi	https://doi.org/10.52842/conf.ecaade.2008.249
summary	This paper presents an approach to creating an online real time rendering environment, upon which a large-scale, urban 3D model can be produced as a collaborative effort between initial content creators and outside parties with an interest in simulation and visualization. In 2007, the City of Atlanta, Georgia organized a taskforce to provide recommendations on the future development and mobility along the city’s signature street, Peachtree Street. To aid in the visualization of this area, datasets were converted into low polygon textured 3D models for the entire study area. This content will serve as the foundation of a collaborative effort to complete a high quality real time environment. The process for this project will be described and the means to extend the boundaries, maintain, and collaborate with this content will be proposed.

title	Mobile Augmented Heritage: Enabling Human Life in Ancient Pompeii
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 396-415
summary	We propose a new methodology for real-time mobile mixed reality systems that feature realistic simulations of animated virtual human actors (clothes, body, skin, face) who augment real environments and re-enact staged storytelling dramas. Although initially targeted at Cultural Heritage Sites, the paradigm is by no means limited to such subjects. The abandonment of traditional concepts of static cultural artifacts or rigid geometrical and 2D textual augmentations with 3D, interactive, augmented historical character-based event representations in a mobile and wearable setup, is the main contribution of the described work as well as the proposed extensions to AR Enabling technologies: a VR/AR character simulation kernel framework with character to object interaction, a markerless camera tracker specialized for non-invasive geometrical registration on heritage sites and a PRT mixed reality illumination model for more consistent real-virtual real-time rendering. We demonstrate a real-time case study on the actual site of ancient Pompeii.

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

title	COMPUTER GAMING, BIOTECHNOLOGY AND ARCHITECTURE: EMBEDDING THE INTERSECTION WITHIN AN ARCHITECTURAL CURRICULUM.
source	AASA2007
summary	Today, leading computer games provide real time environments including spaces, objects and characters that range (by manipulating an enormous array of parameters and being subject to simulations of real world physics) from the super realistic to the super delirious. Biotechnology, although apparently unrelated, also requires the manipulation of information in space and time and promises to affect environments in a range of ways that is at least as extreme. The opportunities suggested by an intersection between Architecture, Computer Gaming and Biotechnology were instrumental in the creation of courses and topics for students in first year right through to students studying toward a Masters degree. This paper reflects on and critically reviews the implementation, strategies and outcomes of embedding the intersection between Computer Gaming and Biotechnology within an Architectural curriculum. It draws from the experience of over 500 students, two Universities and major technological shifts. It develops the notion of the experiment in design. In contrast with the introduction of computer gaming technology into a core first year course, that had the underlying aim of including these technologies as a part of a general design curriculum, the introduction of issues connecting architecture with biotechnology (through computer gaming technology) reflects the specific research agenda of the author and is not intended for general application across an architectural curriculum. For more general application it could be seen as a strategy to promote cross disciplinary collaboration through the concept of the ‘boundary object’.

title	Collaborative Cooling Load Analysis Software for Public Participation on Energy Conservation
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.o0s
summary	This article is part of a research on developing cooling load analysis software for energy conservation. This research focuses on developing the system of Collaborative Design and Public Participation System which allows property owners, architects, engineers as well as others outside the field, to contribute to design process based on the concept of energy conservation within the collaborative virtual environment. The combination of the two ideas between collaborative virtual environment and Analysis Engine of cooling load calculation changes the traditional working processes in which architects and engineers work separately. From the traditional process where both architects and engineer redevelop the whole project from the beginning when redesigning is in need, this new collaborative process requires less time and energy from both parties due to the simultaneous participation of architects, engineers as well as other contributors. In this research, Microsoft© Direct3D® - API based Virtools® is used to develop Real-Time Simulation and its internal script in the calculation process. Through the implementation process, the study aims to develop the 3 components of 1) urban area database illustrating simulating maps for users 2) Graphic User Interface (GUI) connected to other software modules for further expansion and 3) Virtual Network Environment allowing multiple users to log in and use the programme at the same period of time.

summary	Cities are invaded by a variety of synthetic representations, as they can be explorer or virtually visited by the omnipresent Google Earth, as well as interactive maps, digital reconstructions, photographed ours or panoramas, RT cameras, etc. Furthermore, they can be hosted at websites complemented by multimedia, which allow, with little time and effort, have a preview that conditions us before the in situ experience of the real places. Besides the general use that can be made of these powerful media, we consider the potential influence that they cause in the disciplines that are involved with the urban space.

summary	Spurring new and innovative building design will be critical to the urban energy and economic future of the nation. The operation of completed buildings account for 48% of the nation’s annual greenhouse gas emissions, and 76% of all electricity generated by U.S. power plants goes to supply the building sector. Therefore developing and applying new and innovative sustainable building design will have a measurable impact on the environment. Recent studies show sustainable building design is closely linked to system integration, where various components of a building work in confluence to produce synergetic benefits. As a result, a critical component of sustainable design involves a clear understanding of building systems operation, interaction, and the selection parameters. A consideration of suitable building systems, gauging their interaction, and proposing well integrated systems can lead to producing efficient models of sustainable buildings with minimal impact on the environment. The following paper outlines the progress on a project entitled “Building Literacy: the Integration of Building Technology and Design in Architectural Education.” The project develops a digital tool for teaching/learning architectural technology from an integrated systems perspective. The project attempts to immerse students in a simulated environment that is based on the real life practice of architecture. The project accomplishes this by harnessing the capabilities of simulation and dynamic modeling programs, as well as the state of art graphic media, to create compelling and rewarding reasons for students’ engagement in the lear ning process. The project involves a multidisciplinary team of faculty from Florida International University, University at Buffalo the State University of New York, and Iowa State University and is funded by the US Department of Education for the period of 2007-2011.

doi	https://doi.org/10.52842/conf.caadria.2007.x.m0v
summary	Urban design is traditionally regarded as a highly collaborative activity and its costly nature dictates that errors and oversights could easily induce budget overflow and time waste. Augmented Reality (AR) technology, the addition of virtual entities into the real world view, once complemented by the versatile nature of embodied intelligent agents, is envisaged to be promising for supporting design assessment and collaboration within design team. The paper presents a visualization and simulation framework for an intelligent agent-based AR system, called Augmented Reality-based Urban Designer (ARUDesigner), which could allow designers to assess virtual urban designs in a real and familiar workspace. The paper also presents the initial prototype of ARUDesigner and the experimental evaluation results from a pilot study.

summary	This year, for the first time in history more people are living in cities than in the country. This fact induced us to look at the topic of city modeling from different sides. In this paper we introduce novel approaches that contribute to the generation and visualization of dynamic complex urban systems. We distinguish reality-based and generic city models. On the one hand we look a three dimensional models of urban environments. On the other hand we are looking at the key challenges and trends that will shape future cities. We are drawing parallels to functional models of brain circuitry. City modeling as a case in point provides the basis for our research to arrive at a transdiciplinary theory of design and modeling.

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.

summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

title	Best Practice for Achieving Real-Time Virtual Reality Architectural Visualization

summary	Real-time rendering is the most fundamental aspect of the virtual reality technology, which is always, a balance between hardware advancement and efficient software algorithm upgrades on the one hand and the demands of the quality output on the other. As architects who utilize this technology, what we can do as users is to optimize the parameters we can control in the files we input to run the simulation. Thus the identification of the few variables we can control to prevent a lagging performance or ghosting which is no longer realtime. The frame rate above all is the measurement to determine whether a simulation is real-time or not. The research aim is to identify the biggest contributing factors among the few identified. The intention is to save time and effort by optimizing the selected factors in projects so that we do not have to optimize all of them. The workflow will also be a lot faster and projects can be done efficiently. The final part is to run satisfaction tests among users to evaluate those biggest contributing factors and the qualities acceptable by users. This is to eliminate the added processing power needed to run bigger files if they do not contribute much to improved quality.
