title	Does Color Have Weaker Impact on Human Cognition Than Material?
source	Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 373-384
summary	This project intends to develop a method for using virtual reality (VR) to represent a built environment for simulating environmental influences on occupants. Objectives of the project were to explore: (1) what environmental stimuli would affect habitants’ perception, and (2) what possible factors in the built environment would affect occupants’ cognition. An office was selected as the subject of study. Methods were to create a number of digital models, each containing an embedded variable, and then test the impact of environmental influences on visual perception. Results obtained in this study indicate that materials have stronger impact to human perception than colors, and VR has great potential for design decision making and post-occupancy evaluation.

title	Web Based BIM for Modular House Development: Query Approach in Consumer Participatory Design
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. 559-570
summary	The paper describes the relationship of client’s requirements and available design options of the proposed system by examples of its current prototype. By integrating the nature of modularity in prefabricated housing design, a proposed web-based design system will provide information filtering questionnaires to assist customers in selecting appropriate design components. A methodology has been developed that can generate design options based on the client’s needs and available modular components from selected product suppliers making it possible to simulate the final design before processing orders for assembling and manufacturing. Overall, the research demonstrates the power of internet that acts as a feedback loop to receive the information from clients, streamline the communication in between design teams, and integrate all products and materials together.

title	A Choice Model of Mass Customized Modular Housing by Internet Aided Design
source	Joint Conference Proceedings of International Mass Customization Meeting 2007 (IMCM’07) and International Conference on Economic, Technical and Organizational Aspects of Product Configuration Systems (PETO’07), pp. 61-75
summary	The Internet has increased the opportunities to apply the concept of mass customization to customer interaction by tailoring the content to individual needs. Within limited design parameters, customers can determine what options they wish by participating in the flow of the design process from the beginning. This concept has already been implemented in the computer, clothing, and automobile industries, but it has not been fully integrated in architecture, especially the housing industry which is more directly related to personal life style. The industry lacks a process that will lead to the customization of homes that respond to the unique values and needs of the occupants. The paper describes the relationship of client’s requirements and available design options of the proposed system by examples of its current prototype. By integrating the nature of modularity in prefabricated housing design, a proposed web-based design system will provide information filtering questionnaires to assist customers in selecting appropriate design components. A methodology has been developed that can generate design options based on the client’s needs and available modular components from selected product suppliers making it possible to simulate the final design before processing orders for assembling and manufacturing.

title	Integration of 3D Tool with Environmental Impact Assessment (3D EIA)
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. 51-66
summary	Environmental Impact Assessment (EIA) tools have been available for some years now and their function is predominantly to predict and identify the environmental impact of building projects. However EIA analysis is often done after the completion of the project or building and when it is too late to influence the design, materials or components to be used. Also, more than 80% of the design decisions that influence the whole life cycle of a building are made at the initial design phase. EIA does not receive the required attention. A new approach is suggested in this research to ensure that designers, clients and stakeholders have all of the relevant information needed at the outline design stage for the assessment of cost and environmental impact. The idea is that building owners and users will have the opportunity to minimise their operating costs from ‘cradle to cradle’. As energy resources reduce over the next few decades, the value of this research will increase and it is possible to foresee government legislation which drives building construction in this direction. By making environmental impact analysis readily linked to 3D products at the very early stage of the design process, the value of 3D technology will be enhanced significantly resulting in more use of the technology in the construction process. In this context, the objective of this paper is to introduce and explore approaches for developing integrated 3D- EIA, LCA (Life Cycle Analysis) and LCCA (Life Cycle Cost Analysis) and VR (Virtual Reality) tools and develop trade-off analysis to assist in the decision making process. To demonstrate initial results, a pilot case study in the UK is being developed.

title	Various Media in the Design Process and Methodology
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8j
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	The paper describes the mergence of traditional architectural design processes with approaches that rely on digital media and software for the creation of architectural space. The depicted projects are part of a ‘work in progress’ process, with a recent studio that is set up to apply the so far accumulated experiences. Within the projects, focus is on those design phases where the applied media and methodology is changed and where the back and forth between different media and the depth of their implementation is perceptible in, and / or has a significant influence on the design itself. Through a line of successive experiments, the paper explains the development of a possible method that utilizes a variety of today’s accessible tools in architecture, making use of phenomena that appear when changing from one tool to another. Goal is to avoid limitations that are existent by the solely employment of one media or method, and to understand the fusion between different media as an inspiring momentum to develop the design further. The paper draws a line from an initially experienced and analyzed design method over several projects in practice and academia to conclude with a possible design method that could be established successfully in both fields of architectural teaching and practice. Initial experiences had been drawn from professional practice, in which the digital realm was limited to a support device of the design process. The first project that is described in the paper, explored the employment of digital media as a possible tool to drive the design process in a broader sense. The studio setting was organized as a laboratory for the exploration of the change of applied media. Focus was on the influence on the design progress. The design method required of the studios participants was not exclusively based on an architectural program, but on an initial, very conceptual process with an artistic approach, based on personal experiences of each participant. This was meant to detach the students entirely from architectural processes and mindsets they had picked up so far. Parallel to that kind of an intellectual process, studio participants learned to handle Maya as the 3D modeling software of their choice. Both the technical knowledge and the artistic projects were merged in a second project phase, in which participants had to further develop their work by applying a very effective mix of various design tools. Using digital media as a parametric design generator, subsequent projects were developed. The task for the designers here were to decide what kind of algorithm could be applied to which process and when it was to be stopped for the best result. Applying such an automatism successfully to the design process, the employment of traditional media and methodology remained, to adapt the digital driven schemes to the required design task. The diverse design experiments demonstrate important aspects when merging complex design and animation software with traditional design processes. To achieve good architectural design results, all examined projects showed that traditional design methods with its physical models are hardly replaceable to its full extent by other media, but digital media are able to strengthen design processes and invite designers to explore new means of design work.

title	Automation of Passive Solar Design System
doi	https://doi.org/10.52842/conf.caadria.2007.x.l5x
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This research, focus on the automation of passive solar design system using computational method. The quantitative nature of passive solar design system makes the automation possible. The automation is done in stages, because implementing the passive solar design system is not an isolated process, but intertwined with the overall design process. The first phase of automation concentrates in conceptual stage, to avoid major deviations in later stages of the design. The conceptual stage use Eco-grammar (A preset Design guidelines for corresponding climate) and user inputs for initial form generation. The second stage of automation is done after the user finalize the model with respect to its position rotation and arrangements. In this stage manipulation of vertex, edges and faces of the forms were manipulated using genetic algorithm. The value of mutation or crossover done in genetic algorithm is suggested by knowledge engine (preloaded design knowledge). Until the form obtains or reach closer to the desired values of performance the loop between analysis and mutation, crossover will be continued. On the basis of analysis result further manipulations may change from the previous which is guided by the knowledge engine.

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
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, 146-155
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.

title	Simulation Software Development for Urban Landscape Possibility Analysis
doi	https://doi.org/10.52842/conf.caadria.2007.x.u9u
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This research paper proposes a simulation software development for possibility analysis of urban landscape development project. Normally, analysis of land potentiality and feasibility study for investment are necessary pre-processed for supporting urban planning, developing and architectural designing. However, most available tools are usually tailor made for each process individually, causing difficulties in information interchange between each processes. In this research, we propose a policy making support system for urban planning project development providing several functions such as testing land use and its physical character which are important to urban expansion and architectural design based on impact analysis of urban comprehensive plan. The proposed integrated system consists of a topological analysis module, constraint checking module and geographical information processing module. First, Geographical information stored in 3D graphic file format is converted to object-oriented data model and stored in a database. With several constraint and regulations, the stored information is then checked in the landscape topological analysis module. In evaluation process, the developed software is tested with geographical information of Bangkok area under constraints and regulations of Building Control Act of Thailand. While controlling building properties, the software can model the buildings and generate urban physical character. The result is then checked by several urban landscape planning experts. Experimental result shows that proposed system provides flexibility in information interchanging with constraints and regulations updating without system reconfiguration. The system also provides internet accessing for public participation in the process of making urban comprehensive plan.

title	The Dynamics of Physical Ambiences
doi	https://doi.org/10.52842/conf.acadia.2007.174
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, 174-181
summary	This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. 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.

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.

From the analysis of a number of structured interviews with practicing designers, key design scenarios are identified. These scenarios are then generalised and outline guidelines developed for structuring early stage design, making use of TRIZ methodologies.

title	X-House – A Game to Improve Collaboration in Architectural Design
doi	https://doi.org/10.52842/conf.ecaade.2007.141

summary	The current research we are conducting refers to a general model of architectural design. The complexity of the present-day design process is such that new ICT tools are required to consciously and appropriately govern the design choices. In particular, the tools that involve the early phases of the design process, when the choices crucial to the entire building process are made. In this perspective we are developing, together with a general model of architectural design based on Collaborative Design (CD), a simplified version of it – the _-House game – that can be used to help university students appreciate the complexity of doing architecture and building. This “simplified version” of the general model is therefore a useful ‘design training tool’ in the case of complex problems that can be solved by means of iterations, trade-offs, creativity, and group work; and at the same time makes it possible to highlight, define and link relatively little known aspects of design, such as scheduling, relations among operators, decision-making mechanisms, and process and design priorities.

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.

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	Tagging Your Body Virtually : Represent a place making process with social network
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. 543-558
summary	This research focuses on the virtual environment of place making. In this paper we would like to emphasize that the place making should be stressed collective views in order to obtain the design application of possibilities. However, in past researches there has been no study that tried to collect the collective views by digital ways. Accordingly, this paper proposes a response thought the Spatial Intention. It could be used to represent the human of body experience. The "moving" and "standing" are appropriate to two main considerations. Both of these could be connected to the action of "focus" and "choice." these leads to a sequential relationship of place production. The positive significance of the spatial intention lies in the convertibility of physical experience could be implied with a specific understanding. It also could be used to mold the place of knowledge structure. Thereby in order to verify the reliability of the above, we made a social network of virtual environment and used the rapid prototyping method to develop a prototype system. Implementing on the Chinese garden of the actual case, we found that the tag could concentrate as an entire sense in somewhere of place. These tags also could be shared remotely through the social network. Different tags in the sharing mechanism could collage out a place of collective views. This perspective would be used to assist designers to understand the sense of place. It also would be applied to find out the environmental design of possibilities in the future studies.

title	Solving Design Puzzle with Physical Interaction – A Collage Table Implementation
doi	https://doi.org/10.52842/conf.caadria.2007.x.o6o
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Design process can be treated as a puzzle exploration process. With puzzle exploration as the interactive metaphor and mechanism, design collage reframes the design visual information as an interactive puzzle-solving game. Based on the design puzzle researches, this paper adapts an intuitive interface approach - physical interaction. A system using multi-touch technology (FTIR) called Collage Table has been implemented as the device to combine a design collage game with the physical interaction. The mechanism for invoking the search is developed and elaborated, and the implementation (both in software and hardware) and possible interaction are also documented in this paper.
