title Information and communication technology (ICT) and intelligent cities: A Malaysian experience
source In Mao-Lin, C. (Ed.), CAAD talk 4: Insights of digital cities (pp. 229-248), Taipei, Taiwan: Archidata
summary This paper reports on Malaysian’s experience in suggesting and maintaining two cybercities (i.e. Putrajaya and Cyberjaya) or Intelligent Cities. The advantage of the convergence of technology has been implemented at national level as a means to increase human participation and to prosper in the Digital Age, in their daily life, business, education and other urban activities. It starts with an overview of ‘High-tech Corridors’ in Asia countries namely Philippines, Thailand, South Korea, and Singapore and its impact to these countries. The foundation of this study presents the criteria of Intelligent Community (IC) that makes a city intelligent without excluding the value of the citizen quality of life, culture and religion by associating with the Information and Communications Technology (ICT). We introduce and present www.i-Putra.com.my, a portal of digital soft city of Malaysia’s new administrative Capital, Putrajaya. This national project is funded by Putrajaya Holdings Sdn. Bhd. Malaysia and was originally developed by the Multimedia University before finally executed by I-Design Sdn. Bhd. It is designed to be an interactive channel to provide the services for different level of target audiences of the civic and urban activities. The guiding principle for i-Putra.com.my portal is content, context, community and commerce in which they will be integrated with the city information such as residential, commercial, service and public areas. It is hoped that this paper gives an example of good intelligent city concepts through a clear vision and planning, effective management, implementation and sustainable approach.

title Urbamedia: the design of an integrated system of urban-building visualization and communication
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 603-608
summary This paper presents the advancements of the Urbamedia project which was designed as part of a research program at the Center CAO (Creation computer assist), School of Architectural Design and Urbanism, University of Buenos Aires, which was led by the valued master and advisory professor Architect Arturo F. Montagu. This proposal of the city of Buenos Aires on the Mayo Avenue expands the original historical fragment presented between the following two referenced representative landmarks: The Two Congresses Square and the Mayo Square. It continues with the advancement of methodologies and techniques implemented in a system of “integrated visualization and communication” for the development of a VRML (Virtual Reality Modeling Language) 3D virtual non-immersive and interactive vision. It also incorporates the development of a “foundation of digitally integrated knowledge” with fragments of central areas from other surrounding cities as well as interfaced phenomenological situations. The application of digital VRML technology has allowed for thoroughly researching the processes through dynamic simulation of specific urban fragments (Mayo Avenue within Buenos Aires) and the cities that are also participating in the project.

title A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
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. 539-556.
summary If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title The Effect of Stereovision on the Experience of VR Models of the External Surroundings and the Interior of a Building
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 391-398
summary Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

summary Research on contemporary habitation spaces is directly related to the study of the relationship between new media and everyday life. This paper presents ongoing in-depth research which intends to discuss these relationships in different ways on a conceptual basis. A collaborative multi-users interface is being specially designed, supported by different kinds of electronic equipment. Furthermore, the project’s objective is to analyze how these information and communication technologies are to be used, as well as their impact on poor communities. As a hypothesis, our intention is to verify if the access to information will be able to broaden social interactions and improve new services which have been set up, in order to guarantee a better quality of life. Beyond being a conceptual approach, the study intends to present and examine facts obtained from intervening in a poor district in São Paulo city, Brazil. Using an existing public telecenter as an access provider to the internet, individual TV-connected set-top boxes in 220 apartments in a local social housing complex are being installed, enabling users to communicate through a collaborative multiusers digital interface. Adding a virtual instance to a geographically-based community, the aim of the project is to provide new possibilities to improve dialogue and debates, to encourage more income and cultural activities. It also intends to evaluate the effects of the technological mediation of social relationships, both inside and outside the community, as well as within the physical urban space such as in the dwellings. The results of this study will be useful in defining public policies to be implemented by the Sao Paulo Local Government. The work is being sponsored by FAPESP, which is the Sao Paulo State Funding Agencie, but also by public institutions, private partners and universities. Researchers involved belong to complementary fields such as architecture, urbanism, computer sciences, social sciences, psychology and electronic engineering.

title Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades
source Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 12-23
summary This paper is based on a comparative analysis of some twenty-six intelligent building facades and sixteen large media-facades from a socio-psychological perspective. It is not difficult to observe how deployment of computational technologies have engendered new possibilities for architectural production to which surface-centeredness lies at that heart of spatial production during design, fabrication and envelope automation processes. While surfaces play a critical role in contemporary social production (information display, communication and interaction), it is important to understand how the relationships between augmented building surfaces and its subjects unfold. We target double-skin automated facades as a distinct field within building-services and automation industry, and discuss how the developments within this area are over-occupied with seamless climate control and energy efficiency themes, resulting into socially inert mechanical membranes. Our thesis is that at the core of the development of automated façade lies the industrial automation attitude that renders the eventual product socially less engaging and machinic. We illustrate examples of interactive media-façades to demonstrate how architects and interaction designers have used similar technology to turn building surfaces into socially engaging architectural elements. We seek opportunities to extend performative aspects of otherwise function driven double-skin façades for public expression, informal social engagement and context embodiment. Towards the end of the paper, we propose a conceptual model as a possible method to address the emergent issues. Through this paper we intend to bring forth emergent concerns to designing building membrane where technology and performance are addressed through a broader cultural position, establishing a continual dialogue between the surface, function and its larger human context.

title A Representation Language for a Prototype CAD Tool for Intelligent Rooms
source Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
summary Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

title A 3D Model of the Inner City of Beijing

summary This study has two major concentrations: 1) exploring methods of creating a digital city model, and 2) applying the model to study urban spatial structure, an issue of particular interest and importance to urban planners. Based on existing studies that primarily address two-dimensional (2D) urban structure, this paper focuses on the three-dimensional (3D) structure relating to the 3D urban form. Given their greater clarity and possibilities for quantitative analysis, both 3D digital urban models and GIS spatial overlay analysis methods hold tremendous potential for analysing and predicting future urban form. In this project, the Xidan Business District in Beijing's Inner City was the area selected to implement the digital-city application. Under the hypothesis that the existing urban spatial structure is determined by the city's urban planning scheme and current urban marketing forces, it is found that actual urban development does not follow the planning restrictions on zoning and building height regulations. Some contradictions and conflicts, such as building location and height, appeared in the studied district. The specific reasons for the discrepancies need to be further studied.

summary This paper describes how the application of interactive three dimensional computer modelling enables students of architecture to gain a comprehensive insight into how buildings are made. An intimate exploration of what can be, in the student’s perception, a lacklustre subject area is revitalized through the use of virtual building models and introduces the student to the potentials of this medium in communicating their own design work. In addition the published case studies are navigated as one would a web site which is a familiar and comfortable format for the student. Original working drawings and specification provided by architects are utilised in generating detailed three dimensional virtual models of the complete building along with larger scale detail studies of particular building components. The models are then animated or transferred to VRML format for publication within interactive case studies. The case studies may be accessed via the department server for use by staff during lectures and seminars or informally by the individual student.

title From CAD to VR – Implementations for Urban Planning and Building Design
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 399-405
summary At present time, three-dimensional objects are often represented with 2D-data in urban planning and building design. In order to get all the involved parties to fully understand a certain project, this may not be enough. More and more projects therefore take use of the Virtual Reality (VR) technique as a complement to traditional 2D drawings and sketches. All the involved parties can then share a common frame of reference for all discussions regarding a certain project. Unfortunately, the technique is not yet adapted to fit the current building design process. In this paper, we present a solution for semi-automatic generation of a VR-model based on 3D CAD information and aerial photos obtained from the City Planning Authorities in Sweden. The data is imported to support real-time editing of terrain, roads and buildings. We also present a framework for importing 3D-models created in Autodesk Revit which enables a seamless integration of modern 3D CAD and VR-models. The features are implemented in a software developed at Chalmers Visualization studio (Gothenburg, Sweden) and technical details about terrain handling and speed-up techniques will be given.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 591-596
summary Urban building codes include a series of abstract geometric and mathematical prescriptions whose final built result is not easily visualized by non-technical users. This makes an informed public debate about the proposed regulations difficult and leaves the final definition of the exact ratios and formulas in the hands of local governments’ technical consultants. Even these experts usually have only gross numerical approximations, photomontages and other non-rigorous representations of the final built environment on which to base their decisions. We propose a system which, taking as its inputs the roads and lots of the area under consideration, as well as the proposed building codes, generates a detailed three dimensional model that gives neighbors, users and authorities’ access to a common, objective preview of the foreseeable result of the codes under consideration. We believe this will lead to a greater transparency and participation in building code definition and approval processes. [Full paper in Spanish]

title Perceptual and Cognitive Factors that Influence Orientation in Computer Generated Real Architectural Space
source International Journal of Architectural Computing vol. 3 - no. 2, 245-254
summary This study presents results from an experiment that concerns spatial perception and cognition in virtual environments. It also includes the effects of how the development of a simulated virtual space can change perception and cognition of a real building perceived only through architectural drawings and photographs. In the experiment each student was shown external and internal 360° images, representing nodes in virtual space, of the same virtual building. Two different groups of students were formed. The first group was shown photorealistic rendered images, while the other group the same images with non-photorealistic representation. Differences in orientation tendencies of the participating students, as well as statistical results from these experiments were tested and are presented in this paper. It was found that there was a statistically significant tendency of the students towards larger scatter in more luminous virtual space as well as a tendency to visit lit parts of virtual space.

title Designing with machines
source Proceedings of the Dresden International Symposium of Architecture 2005, Technische Universitaet Dresden, P. 225-229
summary In 1845 Edgar Allan Poe wrote the poem “The Raven”. An act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on a basic approach to describe principles in architectural layout planning in the form of mathematical rules that will be executed by the use of a computer. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, an exemplary method will be described to solve those problems. Mathematical and syntactical difficulties that arise from the attempt to extract rules that relate to the process of building design will be pointed out. As a consequence for teachings it will be demonstrated which competences are needed in order to aid designing with machines.

title Adaptive Kinetic Architecture: A Portal To Digital Prototyping

summary This paper presents a definition for adaptive kinetic structures in architecture, generated from an examination of research in engineering and architecture. This characterization introduces the challenges presented both by modeling form and environment, and simulating their interaction. Adaptive kinetic structures react to a changing environment, as well as generate their own. These conditions make them appropriate subjects through which the design and implementation of tools for ‘digital prototyping’ may be explored. Digital prototyping serves performance and simulation-based design. In general terms, it is an interdisciplinary integrated approach for modeling, predicting, and analyzing the behavior of a system. It is at the core of virtual engineering. In the aerospace, automobile, and manufacturing industries, it is practiced extensively through discrete-event and continuous simulations, as well as simulation environments. This paper provides an overview of digital prototyping commercial software for engineering applications that can be transferred to architecture, and identifies some of the unresolved issues. It thereby extends the vision of the comprehensive building information modeling initiative.

title A Multi-dimensional Exploration of Urban Attributes by Data Mining

summary The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970’s in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity’s database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; • Can help in the design process by providing site-specific insight through deeper understanding of urban data. • Can produce results that can assist architects and urban planners at design, policy and strategy levels. • Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

summary This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

title VR-CAVE as a multimodal interaction environment
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 413-420
summary This research focused on building a software system on VR-CAVE for multiple users’ interaction with various media, alongside simultaneous communication amongst users. While all users interact with virtual objects in VR-CAVE concurrently, by means of several kinds of input device, including conventional mouse and keyboard, PDAs, mobile phones and laptops, users can communicate with each other through the most natural way at the same time. The system prototype was implemented and still in development for extension on the strength of supporting more input device and media formats. Further research would make VR-CAVE not only a representing tool, but a platform for design communication and evaluation, or a collaborative design environment.

summary The paper is a follow-up to earlier work investigating the research hypothesis that Virtual Reality (VR) is nowadays a maturetechnology, suitable for communicating planning ideas. A work in progress involving the redesign of two squares within the urbanfabric of a deprived Athenian neighbourhood is presented. A VR model of existing and proposed layouts was constructed, focusingon accuracy of visualisation, ease of navigation, online spatialized commenting mechanism and ease of access. User groups weresupported with appropriate training—researchers had the opportunity to observe the reactions of people and deliver questionnairesthat help identify problem areas related to technophobia, disbelief, past knowledge, communication skills, understanding of thevisualisation system used, usability of the navigation system as well as the commenting mechanism. Gender and social exclusionare key issues in this particular multicultural neighbourhood. Collecting demographic data on all participants (age, sex, educationlevel, employment, marital status, etc.) during the commenting process enables a series of analyses testing the ways the system isused.

title Multi-touch - the future of design interaction

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 The central feature of the project is the development of a computer and its interfaces to simulate urban space and, in the context of an intermedia city tour, to allow citizens to creatively influence their urban space by manipulating media structures at chosen points throughout the city. A master plan is set up to re-cultivate public spaces and points of architectural focus. The city reacts interactively to the commands. A dialog is created between user and public space. The tour route is an open structure which can be expanded at any time. Via interfaces the user activates a reaction in the real city by making changes to the virtual model. This results in a dynamic space, a communication based on the results of this transformation. The user interface allows an information transfer between real people and virtual space. Virtual reality then reacts to the input by transferring that information back to reality. The direct influence on the architecture is effected by a media-transformer. It projects an additional perception level on to reality while monitoring the data via various analysis interfaces.
