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.

summary	In the early conceptual design, individual designers often make extensive use of sketches to explore design problems. Moreover, within the collaborative design sessions, designers communicate and discuss with each other by sharing their temporary sketches. These private design artifacts are used to externalize ideas and share them with other designers in order to facilitate the performance of design sessions. During such social interaction performance, some abstraction behaviors behind social activities like collective creativity are synchronized. However, the existent tele-communication tools proposed for separated design groups, slightly hold back the activities of collective creativity. It makes designers dedicated just in the table discussion, and negatively influenced on collective creativity sharing. Thus, some private design artifacts became isolated in tele-communicative environments. In order to respect this, we propose an approach that uses the notion of Digital Backchannel to realize the sub-channel communications. In this paper, we also present the implementation of a working prototype of groupware application. Finally, we discussed some points from our studies.

summary	Architectural design, due to phenomena such as globalisation of the construction process, delocalisation of professional and industrial activities, spread of new construction materials and components, and the challenges of environmental sustainability, has become so comlex that traditional ways of managing the process are no longer sufficient. What is more, architectural works are required to be ever more performing and integrated - holistic. The paradigm of collaborative design is gaining ground as a way of dealing with these problems. Various process/ product models have been proposed over the years, making more or less use of advanced tools. In this field this study proposes a model in which operators from various cultural contexts are each supported by Intelligent Assistants (agents). The model simulates the design of works of architecture to the best professional practice. Exchange of information and knowledge between the operators is essential to enhance the design process. From this follows the need to interface not just data, but also meanings. This article shows how to improve communications between different applications, used by different operators, so as to integrate information and knowledge, whether formalised or not, in a project managed collaboratively by means of XML.

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	As the field of computer-aided design evolved over the last thirty years or so, it has witnessed five changes of emphasis in research direction. In the first stage, the use of computers in architecture focused on the development of Computer Aided Design (CAD), that is, systems that simulated the use of drafting tools, and research was mainly concerned with the satisfaction of designers' ergonomic needs. In the second stage, there were efforts to use computer tools in non-graphical aspects of designing, such as the use of Data Base Management Systems (DBMS) in the quantity survey of buildings. The concern was to satisfy the cognitive needs of designers by focusing on the way information and knowledge were perceived, acquired, stored, and processed. In the third stage, the focus shifted to the development of realistic models of buildings to permit the assessment of design proposals. In the fourth stage, the focus was on studies concerned with the encoding of architectural knowledge into design tools (KBMS), and the discussion was whether to go towards design automation or design supporting tools. In the fifth stage, with the advent of the Internet and the development of communication tools, research became focused on the collaborative and social aspects of design activity. In recent years, research also became concerned with the exploration of the physical implications of digital media in the production of artefacts. Today, there is a vast range of research interests and approaches, but the quest for new, unifying paradigms continues.

summary	Architects frequently understand and experience design and creativity as a personal and lonely activity. However, there is, increasingly, a need to collaborate with others in the design and construction of buildings. Digital technology is intricately intertwined with the creative and social aspects of the emerging practice world. A prime example is the use of digital fabrication technology and building information models to directly transfer information among architects, contractors, fabricators and consultants. At the same time, the discipline and practice of creative design is increasingly seen as a valuable cognitive skill, to be emulated, tapped, and understood by other disciplines in various settings. Fields outside of architecture and governmental granting agencies have shown strong interest in understanding, rationalizing and importing the creative design process that architects engage in. The obstacle, however, has been that architects and designers are rarely able to explain their processes in a manner understood by others. The advent of digital tools and social computing further complicates the issues of how designers design with such tools and how designers design with others (Lawson, 2005). Our aim should be to define a discipline of collaborative digital design with clear conceptual frameworks, methodologies, and epistemologies. The goal is two-fold: 1) to formulate a discipline of digital design based on sound theoretical and pragmatic underpinnings, and 2) to elucidate the processes of digital design so that we can better communicate them to other disciplines and thus engage more effectively in interdisciplinary research.

summary	Collaboration in design can take place in a physical, social space, in a distributed or virtual environment, or in a combination of both. Design teams use a range of ICT means to support both synchronous and asynchronous communication. While these tools are designed to facilitate collaboration, the collaboration process still requires planning and organisation in a social context, which are activities that students and professionals need to learn. In current practice there is a need for designers and design managers who have the competences to collaborate in design and to organise distributed collaboration processes. At the department of Architecture, Building, and Planning at Eindhoven University of Technology, we have developed a course on Collaborative Design in the Master of Science curriculum. This course addresses both the organisational, social, and technical issues of collaboration in design. The paper introduces the objectives and educational methods used in this course. It describes the experiences of both teachers and students that were gained now that the course was taught in three subsequent years.

summary	Digital archives that use 3D CG models, for example, relating to historical architecture and archaeological sites, are now commonly created for a wide range of purposes. Unlike actually visiting historical architecture, access to digital archives and browsing of their content are computer-related. Thus, users cannot easily gain a deep understanding of the content and are less likely to truly enjoy it. Therefore, in this paper, we propose a method to support collaborative experiencing of 3D digital archives related to historical architecture. To achieve this goal, we developed a prototype system for a 3D digital archive of historical architecture using VR technology. The system offers an interactive interface.

title	VIRTUAL CONTEXT - INVESTIGATING THE CHARACTERISTICS AND OPPORTUNITIES OF DIGITAL VISUALISATION MEDIA FOR SITUATED APPROACHES TO ARCHITECTURAL DESIGN IN AN URBAN ENVIRONMENT
source	Delft University Press
summary	This research initiative addresses the issue of Design in relation to Virtual Context. Central to this study are the innovative potentials and instrumental opportunities of computer based media techniques, capable of generating interactive models and changing perspectives for the benefit of urban and architectural design. The ambition was to not only make a contribution to the existing body of knowledge concerning digital technologies and their applications, but explore theoretical conditions which might help define and stimulate further study. From the outset, the focus was on furthering the opportunities for computer based representation media in creative design. On the basis of a series of explorative studies the subject of this research was targeted: the issue of Design in Context, or more specifically: Design(ing) in a Virtual Context. During the process there was a marked shift in the conception of the subject from – more or less immersive – VR technologies in the direction of approaches which might be expected to become readily available in practice and education and could be effective in actual design processes. This insight also brought about a shift in emphasis from realism per-se towards creating a sense of situatedness. The design representation system which was developed was intended to not just allow for one type of model view, but to afford an array of different views, from which the designer would be able to choose freely, depending on the phase and focus of design as well as personal preferences. A series of interface prototypes and support tools were developed especially and successively tested experimentally. For the intended final design driven experimental study, different virtual context models were considered. Eventually, an integral – purely fictitious – design ‘environment’ was constructed in the computer, so that the workings of the proposed system and its components would be tested systematically. A conscious choice was made for an in depth study, on a relatively modest scale, which would a certain amount of mutual involvement between designer and researcher, to confront the participants with the finer aspects of the proposed system in a relatively short time and to gather detailed data. A half dozen design professionals were invited to participate in a closely monitored experimental exercise. The results of this study therefore do not offer straightforward, indisputable facts, to be considered representative for the design community as a whole, but indicate that the working methods of the individual designers – when discovering aspects of the site, developing and presenting proposals and reflecting on the qualities of represented designs – tend to vary considerably. For this reason the interactive representation system proved to be of value. Participants could express different view preferences, with more or less realistic image modes being used in different phases of their design developments, with varying experiences of situatedness. Some of the design professionals participants were very appreciative of the system’s opportunities, others tended to be more ‘set in their ways’. The results of this experimental study indicate that there may particularly be opportunities for interface applications which are able to function interactively, offering individual designers – as well as others involved in evaluating design proposals – a variety of tools with which to approach specific design artefacts in their changing contexts. Virtual models can play not only an important role as a ‘reminder’ for the designer but also to other parties playing an active role in the design and implementation processes. Interactive environment models are not only promising as exploration tools for existing sites, but could be valuable to test the impact of a design on its location. This could be especially interesting if the site is difficult or impossible to visit or as yet a virtual construction. In addition such an approach might be beneficial for objective comparison and evaluation of design proposals in competitions and in education as well as in on-line collaborative design projects where the context is still in the process of being developed.

summary	VR-based design environment have been traditionally not connected to companies’ design repositories and knowledge management systems. Till now these tools are mainly used for the initial exploration of innovative and original three-dimensional spaces and curves. Our approach encourages the use of VRbased design environments as design tools from where to reuse design solutions and to access design information, which are stored in internal repositories. This vision goes towards the development of a VR-based integrated design platform. Further, today’s knowledge management systems show evident limitations when dealing with multimedia files and 3D models. In order to overcome this limitation a framework for embedding in our VR-based design environment a Knowledge Management system for multimedia content has been developed and it is here described. Our solution implies the use of annotation languages such as the recent MPEG7 ISO/IEC (Multimedia Content Description Interface) standard for metadata, which is based on the XML language. Data types handled in our system are multimedia formats including text, audio, video, images, and 3D models. The main contribution of our research activity is in providing an innovative and original approach for supporting the design process, which takes advantage both of the visualization and design capabilities of virtual reality technology and of the reuse of design solutions directly in VE, through the retrieval of 3D models and multimedia data from various sources.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 321-326
summary	This paper describes and analyses the teaching/learning approach which progressively is being established in the context of the Digital Graphics Post-Graduation Course. The method used has, basically, generated educational situations able to increase the self-learning capacity of the students; develop skills for collaborative activities to build the knowledge and overtake the limits of time and space imposed by traditional educational systems. The theoretical references adopted to draw the didactic situations are explained, these situations include more and more moments of distance learning, synchronous or asynchronous, redefining the attitude of lecturers and students. This work points out the introduction of a tutor, an agent to promote interactions among student/lecturer/object of knowledge; and the investment on production of didactic material specific to digital graphics is emphasized between lecturers and students, exploring collaborative activities to the distance learning modality.

summary	The realization of architecture, that is the building of the physical artifact, requires numerous collaborative participates that requires a communication network in order to realize the vision. All efforts to communicate a design idea prior to physical realization, that is manufacturing or construction, are forms of visualization (i.e. representation). Herein lies the fundamental problem, the designer(s) must en-vision, and communicate that which is to BE ... physical, yet is NOT... physical. In this paper, we will review the emerging Human-Computer-Interface and technology influences on process and product; here we find the “humanistic” component is a critical factor in the success of “digital” strategies.

summary	This paper presents an experience of collective digital fabrication and parametric modeling of furniture made with recycled plastic waste, inspired by natural elements of the Brazilian northeast. In addition to conventional joinery techniques, we highlight the technologies of rapid prototyping (PR) and digital fabrication (FD) (Volpato, 2007, Pupo, 2008; Pupo, 2009); as tools that promote a paradigm shift, both in the design process and in production and materialization (Kolarevic, 2005), allowing recycled plastic to have new applications. We started with a brief review of digital fabrication processes in Brazil, emphasizing collaboration in design and execution. Then, we contain the recycling of plastic and the need for actions for its best destination. Finally, we present a sustainable and collaborative design experience: the modeling and digital fabrication of furniture, entirely produced from recycled plastic, called “Banco Cabaça”.

summary	Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

summary	This paper reports on a study of the role of place in a virtual learning environment for digital media design. Using an immersive 3D Virtual World based on Active Worlds, we have created a virtual learning place for students in a Website Design course. The virtual learning place has two distinct parts: a classroom-like place surrounded by student galleries. Students can navigate and communicate (synchronous chat) within the environment in the form of an avatar (virtual person). We recorded the conversations and activities of the students in discussions held in the virtual learning place and applied a communication coding scheme to analyze their discussions. In this paper we present our approach to developing an understanding of the role of place and evidence of its effect on the conversations of design students in a virtual learning environment. We show how we identified the characteristics of place and specifically how it provides a context for identity and presence for supporting collaborative and constructivist student centred learning.

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	Virtual Architecture as Representation for Creative Design Process - Through a Collaborative eDesign Studio

summary	Using Virtual Architecture (VA) as a general scheme for representations to sustain the reflection activities involved in the design process can help students to initiate creative design ideas. Because of its implicit abstract nature, VA can be used, to represent original ideas or processes, or well-known architectural theories to articulate design ideas. Furthermore, VA as a mean of expression, turn out to be a source of inspiration for students who perceive it as medium with very few limits with which to develop, explore and express their design intuitions. A recent collaborative edesign studio experience is reported to illustrate the benefit observed. Using three examples out of ten student projects, we show how designs and design process have been characterized by those virtual representations. In fall semester 2004, the edesign studio took place between the Schools of Architecture of Toulouse and Université Laval in Québec. VA was both an academic and a studio topic at Laval while the other school students had a traditional design task to tackle, namely the rehabilitation of Chapou University Residences for students in Toulouse. Students from both schools composed each edesign team. In addition, three common architectural themes were web-documented and introduced to both classes: room, as defined by Louis Kahn: “a space which knows what it wants to be is a room”; color, as an architectural medium in dialectic with structure; and body-space relationships, as articulated by Gilles Deleuze and its projection to cyberspace. From the edesign studio results, we are arguing that virtual architecture should be looked at not only as new domain to be investigated by architects and taught in academic studios but also as a new medium of design to develop and explore design intuitions through virtual representations.
