title Computer Renderings – „Reality is Overrated”
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 729-735
summary In this paper, two problems concerning truthfulness of computer-generated visualization are considered. The first one concerns relationships between reality and its representation by computer renderings. The second problem concerns the kind of representations people need. These problems are analyzed for static perception of architectural forms based on computer visualization, and for dynamic walk-through perception of urban space. The thesis of the paper is that many photorealistic renderings are excessively realistic and thus not true. In this context, a new question arises: do we need the true representation of an object? The author claims that we need “adequate” pictures. Adequate means a picture that is satisfactory in particular situation. The problem of equivalence of media (renderings and animations) and reality is not that important here. Much research is concerned with the truthfulness and falsity of information. However, they do not take into consideration that frequently what seems to be real exerts bigger influence on people than what is in fact real. Understanding this problem may help us in producing images that better correspond to people’s expectations.

title Virtual Environments in Design and Evaluation

summary One of the major challenges facing the professionals involved in the home modification process is to succeed in adapting the environments in a way that enables an optimal fit between the individual and the setting in which he or she operates. The challenge originates primarily from the fundamental characteristic of design - one can see and test the final result of home modifications only after they have been completed. The goal of this study was to address this problem by developing and evaluating an interactive living environments model, HabiTest, which will facilitate the planning, design and assessment of optimal home and work settings for people with physical disabilities. This paper describes the HabiTest tool, an interactive model that has been implemented via an immersive virtual reality system which displays three-dimensional renderings of specific environments, and which responds to user-driven manipulations such as navigation within the environment and alteration of its design. Initial results of a usability evaluation of this interactive environment by users are described.

title Some Phenomena of Touch in Study Models
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. 277-287
summary The senses of “Touch” bring people the feeling of reality, and human beings can always naturally sense the tactile impression. Hence we touch things and our sense tells us that our hands are touching something (Hinckley et al. 1999). Comparing to the tools used by designers between traditional and new digital media in the design process, the most difference is in the sense of touch. This paper focuses on the sense of touch to point out the haptic experience which have ignored by the past in design process. Four phenomena will be discussed in details and some useful suggestions given for future study.

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 (, 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 ( , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title How Real Is the Sense of Presence in A Virtual Environment? : Applying Protocol Analysis for Data Collection
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. 188-197
summary This study attempts to investigate the sense of presence in a fully immersive virtual environment. The methodology applied in this study used protocol analysis for data collection. A preliminary experiment was conducted to explore noticeable phenomena to develop a hypothesis for the final experiments. Four different virtual reality models, representing four different kinds of virtual space, were navigated in C6 (CAVE facilities) by two human subjects. Results of the research in this direction have provided valuable understanding regarding the sense of presence in the virtual environment.

title Cornucopia Limited: Design and Dissent on the Internet
source MIT Press: Cambridge, Mass
summary The Internet provides a remarkable demonstration of the persistence of the gift in contemporary commerce. Net enthusiasts seem prepared to donate much to the common good. This generous spirit ought to strike resonances with the culture of design, which generally promotes a creative ethos of generosity, conspicuous display, and exuberance. But the cornucopia of the gift economy is offset by net culture's recent leanings towards consumerism. This book challenges the supposed gift society of the Internet, and supplants the gift by a more compelling metaphor, enjoyed in certain quarters of contemporary design, that of theft, rule breaking, and transgression. The relationship between design thinking and the network economy is characterized by the reckless spirit of the trickster, the crosser of boundaries, and the malingerer in the hybrid and uncertain condition of the threshold. The book thus presents a designer's view of the network economy, drawing on insights from design theorists, economists, philosophers and cultural theorists. It provides valuable insights for theorists of human-computer interaction, architects, designers, and those interested in registering the source and direction of the impulse to create, innovate, and design.

The book examines five metaphors: household, machine, game, gift and threshold. Economic theory is grounded in the household. The romantics and Marx claimed that labor is dominated by the rampant machinery of capitalism. The computer game represents a potent exemplar of new media economics. The gift is presented as precursor to commercial exchange. Coyne subjects each metaphor to scrutiny in terms of how it deals with the threshold, in other words as it is dissected by the cynic or manipulated by the trickster, and other liminal dwellers in the network economy.

'What’s shaping the culture of the Internet? This turns out to be a surprisingly tricky question, one that Richard Coyne explores with verve and erudition.' --Albert Borgmann, author of Holding On to Reality

summary This paper proposes a new paradigm in computer-aided design: hybrid modeling. Considering, on one hand the traditional sketches and mock-ups, and digital techniques on the other, this paradigm fuses the two and proposes a new technique that uses the performance of the digital with the capacities of the analog without replacing or imitating one or the other. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems that do not consider how designers actually work. Furthermore, two principal elements must be considered in the design process: shape and space. These aspects need to be approached with convenient tools that are adapted to the designers. This new paradigm is presented through two new innovative techniques: the hybrid mock-up (for shape) and drafted virtual reality (for space). A review of the implications of this paradigm on the design process is presented. Not only are the techniques fast and easy to learn and execute, but the results demonstrate that the designers can express both their individuality and the idiosyncrasies of their personal representations; important elements that are difficult to achieve with conventional 3D modeling techniques, especially during the primary stages of the design process.

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.

title Creative Design Between Representation and Simulation

summary Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

summary New media and modern building automation have a strong impact on contemporary architecture. So far one could regard built architecture as static. These new technologies introduce a dynamic impulse to architecture. The objective of our research and teaching work is to demonstrate the impact of innovative systems on architecture in daily usage while providing building automation, multimedia integration and facility management services in intelligent networked buildings. These technologies, as described in this paper are integrated in our second year course for students of Architecture. By designing an interactive graphical interface for the lab they were asked to create a spatial scenario as a self running Flash animation. Thus real space is merged with virtual reality.

summary In South Korea, the changing paradigm of family composition toward single-person households and nuclear families has caused the decrease in number of students, which has led to the need for change in the qualitative, rather than quantitative, management of spaces and facilities on university campuses. In particular, since 2005, the merging of universities have accelerated, which has brought up the need for a system that facilitates the management of integrated university systems. Accordingly, universities now require efficient system operation based on three-dimensional and data visualization, unlike the document-based management of facilities and spaces in the past. Users lack a sense of responsibility for public facilities, causing difficulties such as energy waste and frequent movement, as well as damage and theft of goods. This study aims to form an AR-based interface using the ANPR algorithm, a computer vision technique, and the position-based data of the GPS. It also aims to build a campus space management system to overcome the limitations of current systems and to effectively and systematically manage integrated building data. In addition, for module test verification, the prototype is applied to actual campus spaces, and additional demands for campus space management in the AR application are identified and organized.

summary In this paper we attempt to develop a new system called “C-Navi” for construction site simulation and management system. By integrating AR technology with mobile computing, the new system will extend the abilities of AR systems to be implemented in large outdoor space. The concept of 4D CAD system is utilized by integrating related information and displaying them in the time-based visualization approach. Our system could help with decision making and also act as a tool for improved communications between project partners.

summary The main purpose of this research is to explore how body movement can increase user’s sense of presence in the virtual reality cave (VR-CAVE). Traditionally, in architectural applications, there is no interaction between users and VR-CAVE. Visual perception is the major way of presentation. The users feel certain level of sense of presence. Therefore, in order to increase user’s sense of presence, we designed a bodily user interface as our controller which utilized user’s body movement to interact with VR. The contribution is that not only a user can easily or effortlessly control and navigate VR space but also VR navigation will directly link to the experience of walking in a physical space, which provides strong sense of presence to user.

summary This paper introduces a computer-based tool for three dimensional (3D) landscape simulations of housing-layout-design using the concepts of fractals with Iterative Function System (IFS). Housing layout design is defined as a design to allocate many house-units in the undeveloped site. The tool generates a variety of layout designs consisting of multiple dwelling house-units from manual inputs or a template pattern defined as an XML file. Each unit can contain any detailed 3D components found in the residential development such as a house, roads, walls, trees etc. The template defines the transformation rules for IFS including the information of geometrical relationships between the stages in the iteration and of the components used in stop-conditions. The application tool is formulated, implemented and tested. The results in the case studies using several practical sites are demonstrated and evaluated based on the experiments in the design studio.

We make suggestions how architects can design environments that are more flexible and dynamic. These environments are adapted to our changing social and cultural trends. Developments in media and communication technologies allow extending the real world to a so called Tele Reality. These environments will have a certain degree of intelligence provided via computer performance. Humans will be able to receive information form anywhere and at anytime. The focus is on expanding the availability of human resources.

title Keepers of the Geometry: Architects in a Culture of Simulation
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 243-244
summary “Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

summary Traditionally, architecture in its design process employs physical matter, requires physical presence and relies on real world environment using conventional methods of 2D depictions such as paper and pen or 3D representations such as physical models and communicates design ideas in verbal or text-based form. The conventional design process, for example an interior design, a residential house, a commercial complex or even urban design projects, follows the same hierarchy of activities. Efforts are made to the satisfaction of both parties to give the ideas of a physical shape through sketches, drafts and models which may take weeks even months. Finally the project gets its final shape in a working drawing, 3D visualisation or model making. This process is time consuming and somewhat redundant. In recent years technology has offered architects a new tool - the virtual environment. Architects use virtual environment increasingly as device of communication and presentation of design intensions. Virtual environment enables users to interact in real-time with design but unfortunately have not been used widely in the process of design development. The aim of this paper is to investigates the relationship between present design process and the emerging technology of virtual reality, establish a relationship between the two and its influence on architecture to form a new translated design process and communication, an interface between architect and client.

summary As proven in the past, immersive Virtual Environments can be helpful in the process of architectural design (Achten et al. 1999). But still years later, these systems are not common in the architectural design process, neither in architectural education nor in professional work. The reasons might be the high price of e.g. CAVEs, the lack of intuitive navigation and design tools in those environments, the absence of useful and easy to handle design workflows, and the quality constraints of real-time display of 3D models. A great potential for VR in the architectural workflow is the review of design decisions: Display quality, comfortable navigation and realistic illumination are crucial ingredients here. Light is one of the principal elements in architectural design, so design reviews must enable the architect to judge the quality of his design in this respect. Realistic light simulations, e.g. via radiosity algorithms, are no longer the domain of high-end graphic workstations. Today's off-the-shelf hardware and 3D-software provide the architect with high-quality tools to simulate physically correct light distributions. But the quality and impression of light is hard to judge from looking at still renderings. In collaboration with the Institute of Computer Graphics at our university we have established a series of regular design reviews in their immersive virtual environment. This paper describes the workflow that has emerged from this collaboration, the tools that were developed and used, and our practical experiences with global-light-simulations. We share results which we think are helpful to others, and we highlight areas where further research is necessary.

title Architectural space between reality and virtuality: simulation or reality?
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 517-521
summary This study was carried out under the Theory, Epistemology, and Philosophy principles, and is part of the PAAVI Project: The Architectural Design Process in Interactive Virtual Environments. The study presents part of the theory reference landmark that furnishes support in methodology and process approaches to the empirical research groundwork. The study also addresses the dimensions of architectural space and its representation in cyberspace. Comparisons are made between: static space/dynamic space – mathematical laws/architectural principles – interaction during the infographic process and formal manipulation of software – shape/form/function/space/void – distances/effects/rendering. The basic hypothesis is that the decisions made while solving architectural problems demand in-depth thought and ponderation. This is necessary in the light of the project theory, using the computer tools, electronic media, and concepts that structure different software. These software operations interfere in and interact with conception, appropriation, use and the esthetics of space and architectural form. [Full paper in Portuguese]
