summary	While balancing the feasibility of management as well as design quality, design offices with strong focus on design are getting smaller and more compact. Mobility and dynamic information flow are two key issues for information sharing in design studio. In this research, we discussions about these concepts of ubiquitous computing, workflow and information model on small design studio. The goal of this research is trying to use available digital equipments as a ubiquitous device for sharing information dynamically no matter where and when they are. Use such digital equipments as well as server to store information and improve human interaction to achieve better interaction between human and technology. For these issues, we analyze three components of our system—the types of information, the interactive behaviors using roles as a metaphor, and ubiquitous devices that are available for small design studio. Within this research, we propose a system call Ubiquitous Information Flow Tool (UIFO) based on Java and Web technology for testing and reifying the concepts of ubiquitous information flow.

summary	In this paper, we present an augmented reality system that integrates real and virtual worlds for outdoor sustainable education in campus. We develop a mobile spatially-aware computational device as a visualization aid to students learning outdoors. We apply the mobile augmented reality technology to a newly constructed ecological garden in our campus. Users can virtually see the underlying water cycling system outdoors and map the virtual objects to physical reality through embodied interaction with the computational device. The objective is to make invisible information visible to users to extend interactions with our “living” environment. Keywords : Augmented Reality, Mixed Reality, Mobil Computing, Information Exploration.

title	Decision Support System for Modular Houses
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

summary	Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

title	POSTMODERN ARCHITECTURE VS. FENG-SHUI
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 335-346
doi	https://doi.org/10.52842/conf.caadria.2004.335
summary	We start with two paradigms, Postmodernism and FengShui, which seem to be no commonalities between them –western and eastern, new and old–. In both, however, they deeply root in the essence of “place” interweaved culture and social interaction with physical design. Hence, this paper presents a particular viewpoint and method to examine the coherency between the two paradigms. In accordance with the evolution of information technology, a full of metaphoric phenomena and codes within Feng-shui and postmodern architecture is able to visualize by means of computational knowledge. This gives a flexible knowledge-based system to trigger captivating concepts, which are seeds of creative thought.

title	HCIS: the Housing Context Inference System Model for Smart Space
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 759-776

summary	This research is about the basic methods in making computers understand human behavior in an architectural space in regards to reaction to interaction between the machine and human. Its ultimate objective is to analyze the related technology making this series of works possible synthetically on the basis of information system within architectural territoriality. In the end it is expected to offer a theoretical basis to embody smart space, up-to-date and intelligent architectural space. There are two issues that motivate this research: what are the Housing Context and its Inference System, and how smart space can infer the Housing Context and react with proper response. The Husing Context consists of 1) state of user, 2) state of physical environment, 3) state of computational environment, 4) history of user-environment interaction and 5) architectural territoriality. Especially, spatial information of architectural territoriality is a significant key of HCIS. Spatial divisions and boundaries made of architectural elements or facilities determinate their own micro-territorialities. Ontologies are used to describe the Housing Context predicate. In this paper, we can say that the Housing Context and the Housing Log(history of user-environment interaction, a set of the Housing Context) written by ontologies can be a beneficial model of HCIS. Furthermore, we can develop the Housing Log Databases and its variable applications that have enabled to make simulating and analyzing tool of design, the Augmented Web Presence and the other helpful applications.

summary	An open-ended, diversified and critical approach of architectural design, using different form of ideas representation might offer best chances to gain new spatial solutions. Today’s most forward architects and designer are aware of this and make full use of physical and digital media during the process of design. During the summer term 2004 the experiment ‘Crossing the Media’ took place at the Technical University of Braunschweig. The main goal of this practical oriented seminar has been the exploration of the interface between analogue and digital Media within the design process. Both techniques, analogue and digital, were used in an experimental way and their interaction and adaptability in the field of architecture was analyzed. The work examines the possibility of a consistent integration of digital and physical representation in a design process and the individual benefits of each. In order to achieve this, we made up a stringent line of digital-analogue and analogue-digital (DA-AD) Technologies for our design experiment. During the examination we focused especially on the creative potential of the techniques used, their interaction and adaptability in the field of architecture. Hence one of the goals of the occupation with the digital analogue interfaces was the examination of the emerging shift within the structure during the process, the imprints of technology. This paper describes the workflow and tools that were used, our practical experiences with analogue digital interface and the emerging questions and impulses to architects future work and theory. The discovered limitations and consequences of interfaces between the analogue and digital realm of design and their creative chances will be revealed. We share results which we think are helpful to others, and we highlight areas where further research is necessary.

summary	This paper addresses the MASQUE multi-agent framework for generating alternative plans in local land-use planning, In this framework agents represent land-use experts and initiate the development of plan proposals and request each other to express their claims in order to incrementally draw up these proposals. Presented is a probabilistic approach to the implementation of those agents to enable them to make decisions under uncertainty. It is described what personal and collective beliefs they construct and use in order to strategically choose their actions. Negotiation takes place between the initiating agent and the others in order to reach agreement on the incorporation of the claims. The negotiation is organized as an iterative process in which both parties consider conciliatory adjustments of their strategies, and thus their decisions, in order to try to find mutually accepted solutions.

title	Drafted Virtual Reality - A New Paradigm to Design with Computers
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 829-844
doi	https://doi.org/10.52842/conf.caadria.2004.829
summary	This paper proposes a new technique for designing spaces, called Drafted Virtual Reality (DVR), to be used in interior, architectural or industrial design. It proposes the construction of virtual panoramic environments through the QuickTime VR (QTVR) Panorama platform (Apple), starting from sketches made by hand using traditional pen-on-paper techniques. To construct these drawings, the designer uses the computer to build a graphic panoramic template. Using this technique, the designer takes advantage of both approaches, the capacities and possibilities of the computer using VR (3D environments, interaction and real-time), and those of free-hand sketches (abstraction, inaccuracy and ambiguity). These last elements are essential for the first steps of the design process in contrast to the conventional techniques of 3D modeling interacting with mouse and menus. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems very different than how designers actually work. The DVR doesn’t try to simulate analog tools by computers (digital pens), but takes advantage of hand drawn sketches created using analog techniques that are already known by designers and improved by VR visualization. A review of the implication of this technique on the design process. Not only is the technique fast and easy to learn, the results show that the designer can express their individuality and the idiosyncrasies of their personal sketches; important elements hard to achieve with conventional 3D modeling techniques. Finally, this technique can be perceived as a new paradigm in the way we work with computers in design. The limitations of interfaces and usage of current technology are seen when the designer outputs information from the system to process using other analog techniques. The proposed solution marries the existing competencies and techniques of the designer with the advantages of the computer processing. The quality of the virtual experience of this technique is consistent with current designer’s intentions within the traditional design process.

summary	Virtual and Augmented Reality have become common tools in the architectural design process. This technology assists all participants in gaining planning certainty. To interact with the digital models, different input methods are used and adapted by the authors like keyboard, on screen menu, tangible interface, tablet PC and PDA. While every input method has certain advantages and disadvantages, currently tablet PC and PDA best cover the users’ general needs. A usability test shows that reviews with tablet PC are faster compared to other interfaces.

title	STUDY ON COMPUTER-AIDED DESIGN SUPPORT OF TRADITIONAL ARCHITECTURAL THEORIES
source	Technische Universität München
summary	The research presented in this thesis describes a computer-aided design support of traditional architectural theories. Traditional architectural theories in western architecture have been considered as a basis for answering the fundamental questions of architecture: proportion, symmetry, colour, harmony and so on. In particular, the aesthetic aspect of these theories has been one of many important architectural aspects, and which is concerned with the field of architecture in determining the beauty of architectural form. The most significant role of the traditional theories in architecture is to maintain unity, to avoid chaos and then to achieve harmony in a design, using some specific design principles. However, current technology-guided constructions tend to neglect often the importance of these theories due to the standardization of building elements, due to mechanically-prepared construction and the reducing completion costs, etc. Thus, this research proposes a design support system as a design assistant that gives an intelligent advice on architectural design, using analytical design- and ordering- principles of traditional theories for the optimization of the architectural design from the aesthetic perspective. To evaluate the aesthetic quality of an architectural design, this system is implemented in the AutoCAD environment, using the AutoLISP. It is applied so as to explain and develop aesthetic qualities of a design. Designs proposed by this system include optimum designs, which are based on the traditional architectural theories, and new ones which can be in future connected to information models. To do this, the definition of information about building elements is accomplished by using the neutral format EXPRESS and EXPRESS-G for such application systems. The results of the application system are presented, such as the easily generating and quickly conceptualising of an object model, the checking of the aesthetic value of the design during the various design phases, the helping to find direction during rational searching for a solution. The user can easily appreciate the usefulness of the proposed system as a set of tools for searching for rational architectural aesthetics and formal solutions at different design-stages. It is to be hoped that a new "traditional" fundamental of architecture, such as the proposed system, incorporating CAAD systems, will find its place among new technological methods in the AEC industry and so help to bridge the gap between the value of traditional architecture and CAAD systems.

title	An Evaluation of Neural Spatial Interaction Models Based on a Practical Application
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 19-32
summary	One of the serious problems faced by the Brazilian municipalities is the scarcity of resources for building education infrastructure. This asks for an optimal allocation of the available resources that includes, among other things, a rational spatial arrangement of the supply points (i.e., schools) in order to increase the demand coverage (i.e., students). If it is possible to foresee the regions where the demand is going to be concentrated, it is then possible to plan the location of new facilities and to assess the impact on the future level of service of the entire system. Considering that one of the consequences of the location-allocation process is the distribution of trips from demand points to supply points throughout the city, therefore affecting the overall intraurban accessibility conditions to essential services such as education, there is a strong need of models that planners can rely on to predict the future trip distribution patterns. As a result, the objective of this work was to evaluate the performance of Artificial Neural Networks (ANN) when applied to spatial interaction models, the so-called Neural Spatial Interaction Models. This was done in a practical context, in contrast to the more theoretical works commonly found in literature. The practical application showed that the neural spatial interaction model had different performances when compared to the traditional gravity models. In one case the neural models outperformed the gravity models, while on the other case it was just the opposite. The explanation for this may be in the data or in the ANN model formulation, as discussed in the conclusions.

title	A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

title	Crowd Modeling and Simulation
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 161-175
summary	The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.

summary	This paper is reporting on a research project undertaken jointly between the University of New South Wales (UNSW) and the NSW Department of Housing (DoH) to develop a Spatial Decision Support System (SDSS) to assist planning, management and evaluation in areas of high public housing concentration. In the paper we will describe the development of the SDSS, the specific spatial problems challenging the DoH and the potential for the system to incorporate a range of social, financial and physical data, both internal and from other sources, for interaction and presentation in a three dimensional environment. The prototype SDSS attempts to address the specific challenges of providing better service for clients of the DoH. An information audit and survey has been conducted of the department’s resources and needs. Issues identified include the management of high-rise and superlot areas, crime mapping, community interactivity, internal and intergovernmental information sharing, interoperability and maintaining confidentiality and security of data. Interactive 3D visualisation of the model is facilitated by use of the 3map free geospace platform. Use of open source code and open standards such as X3D for 3D graphics interchange allow the project to explore advanced visualisation techniques while ensuring interoperability and data longevity.

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	This exploration attempts to address a new concept, a condition in which digital architecture has started to have a significant impact on the ways in which we live and design. Working practices, social interaction and many other facets of contemporary life have been radically changed. As a time when architecture is becoming digital through the use of computers in the design process and the architecture has became digital through an increasing application of three-dimensional simulated environments to understand and navigate digital information in space. The digital and architecture are being invisibly integrated in a process that is not even apparent to most architects. It makes us aware of the many opportunities that exist between these two design approaches. Instead of trying to validate conventional design thinking in a different realm, the strategy should be to infiltrate design with other media and disciplines to produce a new crossbreed profession. Through an exploration of outstanding digital architecture the detail of generative form, sculptural and curvaceous form, and zoomorphic form, which will have a significant impact on virtual furniture design, can be discovered.

summary	The creation of virtual environments is becoming the alternative for spatial design, while what can be expanded from the real environment is often questioned. This paper proposes the agent interface based on curiosity to create human computer interaction in virtual exhibitive environments. From a social and behavioral point of view, this research explores the use of places as metaphors and simulative human-computer interactions in virtual environments by reactive agents and proactive curious agents based on situation detection. The process is demonstrated by a museum exhibition project. Both the physical and the virtual environment are built, and studied the human behaviors and experiences from their presence at both environments. Agent interfaces are adopted in the virtual environment to enhance people-to-people and people-to-place interactions. The development process, the observation, the interface agent, and discussion based on the findings are presented.

title	A Scenario-Based Agent System for Digital City Interaction
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 693-706

summary	Urban design involves coordination and communication for collecting consensus among citizens and developing the design strategy and spatial program. While these are web-based systems for representing the real world actions, there is lack of human interaction for receiving feedbacks during the process. Therefore, the purpose of this study is to introduce the agents into the participatory design process (PDP) based on scenarios. This paper has developed a webbased system prototype to demonstrate how the agent can interact with users and how the interface facilitates incremental design. We present a participatory design project in an old street to illustrate how the Scenario-Based Agent System (SBAS) model functions in a real application. Meanwhile, four issues will be discussed in regarding with building a learning interaction agent as an actor.
