summary	Paradoxically, one of the most difficult but enjoyable things we do is to imagine. To open the eyes of our mind and see what no one else can see. We see images of things that are yet to be and through the same skill we devise ways in which to make them happen. We design the future in the form of environments, graphics, products, films, and a growing range of new media. Our ability to develop a vision and to visualize it is a gift that we are called to cultivate and put to good use. We have been privileged with a great responsibility. In the process of developing a vision and communicating that vision to others, we “visualize”. Visualization can be a very private experience in which we are alone with mental images that help us shape our vision. In other instances visualization can be a component of mass communication. Visualization can be a means or can be an end. It can be a small architectural sketch on a paper napkin or a mega-graphic covering a high-rise building, an airplane or a ship. In every case, the relationship between vision and visualization is a mutually supportive articulation of what our eyes and our minds can see. Our vision of the role of computers in the art and science of visualization is in constant development. Computer visualization can support an intimate dialog between a designer and his/her vision. It can translate and communicate that vision to a larger audience and in the hands of a new-media artist it can actually constitute his/her vision. The 9th Annual Conference of SIGraDI (Ibero American Society for Computer Graphics) will explore our collective vision on the future of digital visualization and digital media in Environmental Design, Product Design, Graphic Design, Cinematography, New Media, and Art. Authors are invited to share their research work with a focus on how it contributes to shape a collective understanding of the past, awareness of the present, and vision of the future in our multiple disciplines.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	Spatio-Temporally Navigable Representation and Communication of Urban Cultural Heritage
source	Proceedings: VSMM 2005 International Conference on Virtual Systems and Multimedia
summary	Virtual environments are effective tools for the representation and communication of cultural heritage. We suggest that an interactive, immersive and dynamic navigation of the virtual representation of the urban environment will not only convey the essence of the culture and the changes it underwent in a more comprehensible manner, but will engender a 'sense of place'—genius loci— in the visitors. This cognitive mode will help them learn about much more than the geometry and materiality of the city: it will make them 'feel' part of the event itself. By presenting a socially shareable experience, we aim to introduce the medium the character of a genuine place, and make it a social venue for active exploration, discussion and interaction. Virtual reality surpasses both traditional media and 3D-models and offers what they cannot. The affordances of the medium, however, also have the potential to destroy the sense of place it strives to engender. It can do so by allowing a kind of ‘time travel,’ to different periods in the history of the site. This ability locates visitors not only spatially, but also temporally. Everyday experience helps us understand the meaning of spatial boundedness, but does not prepare us to deal with temporal boundedness: sensing the presence of fellow visitors at different times. In this paper we describe our experiences in producing spatio-temporally navigable virtual reconstructions of two distinct culturally significant historic sites: the neolithic village of Çatalhöyük, and the medieval city of Cairo. We demonstrate the use of spatio-temporal navigation through a dynamic, chronologically layered model that can be browsed by multiple users at the same time. Such a dynamic system for representing chronological architectural events requires the extension of our conception of place into the temporal domain. We introduce a new concept, temporal field of view (t-FOV) and discuss how it can aid us in resolving an intrinsic challenge introduced by the representation of the temporal dimension in virtual environments.

title	From Intuition to Precision
doi	https://doi.org/10.52842/conf.ecaade.2005.010
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 10-14
summary	Design has been described as making inspire decisions with incomplete information. True, we may use prior knowledge, we may even think we understand the causalites involved, but what really matters is exploration: of new forms, of new materials, and speculation about the response to the resulting effects. Essentially, this exploration has its own dynamics, involving intuition and spontaneity, and without which there is no design. But of course we all know that this is not the whole story. Design is different to 'craft'; to directly 'making' or 'doing'. It necessarily has to be predictive in order to anticipate what the consequence of the 'making' or 'doing' will be. Therefore we inevitably have to counter balance our intuition with a well developed sense of premeditation. We have to be able to reason about future events, about the consequence of something that has not yet being made. There is always going to be an advantage if this reasoning can be achieved with a degree of precision. So how can we progress from intuition to precision? What abstractions can we use to represent, externalize and test the concepts involved? How can we augment the cognitive processes? How can we record the progression of ideas? And, how do we know when we have arrived? Design has a symbiotic relationship with geometry. There are many design issues that are independent of any specific configurations. We might call these “pre-geometric” issues. And having arrived at a particular configuration, there may be many material interpretations of the same geometry. We might call these “post-geometric” issues. But geometry is central to design, and without appropriate geometric understanding, the resulting design will be limited. Geometry has two distinct components, one is a formal descriptive system and the other is a process of subjective evaluation.

title	BEYOND MODELLING: AVANT-GARDE COMPUTER TECHNIQUES IN RESIDENTIAL BUILDINGS.
source	I Jornadas de Investigacion en Construccion, Madrid, 2-4 June, 2005.
summary	If the result of computer innovations can be interpreted as an emerging “difference” in the quality of constructed space, then in order to truly understand what future applications may be regarding architecture at present, we should look at what advanced functions are available in the process of designing forms and space (DeLuca and Nardini, 2002). Recently the so called parametric approach, a technique for describing a large class of designs with a small description in programming code, has become a focus of attention in architectural computing. In this paper, we reflect on the current use of parametric tools using real case studies as well as our own proof of concept parametric programmes and report on how the avant-garde computer techniques may help to increase the quality of residential building.

title	In-between and Through:Architecture and Complexity
source	International Journal of Architectural Computing vol. 3 - no. 3, 335-354
summary	This paper draws on current research on complexity and design process in architecture and offers a proposal for how architects might bring complex thought to bear on the understanding of design process as a complex system, to understand architecture as a way of organizing events, and of organizing interaction. Our intention is to explore the hypothesis that the basic characteristics of complex systems – emergence, nonlinearity, self-organization, hologramaticity, and so forth – can function as effective tools for conceptualization that can usefully extend the understanding of the way architects think and act throughout the design process. To illustrate the discussions, we show how architects might bring complex thought inside a transdisciplinary design process by using models such as software engineering diagrams, and three-dimensional modeling network environments such as media to integrate, connect and 'trans–act'.

summary	This paper reports about an ongoing experience for the use of computers in the early design stages. It tries to evaluate how recent software developments in the field of CAAD will influence the way architects design and how we teach them architectural design. There is now doubt to us that the ongoing change in the technology will influence the way we work in future when we do architectural design. It is an important question for every school of architecture what effect these developments will have on our teaching and curricula. We use an ongoing educational project to try to find some answers to these questions.

title	Navigating towards digital tectonic tools
doi	https://doi.org/10.52842/conf.acadia.2005.114
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. 114-127
summary	The computer holds a great potential to break down the barriers between architecture and the technical aspects relating to architecture, thus supporting innovative architecture with an inner correspondence between form and technique. While the differing values in architecture and technique can seem like opposites, the term tectonics deals with creating a meaningful relationship between the two. The aim of this paper is to investigate what a digital tectonic tool could be and what relationship with technology it should represent. An understanding of this relationship can help us not only to understand the conflicts in architecture and the building industry but also bring us further into a discussion of how architecture can use digital tools. The investigation is carried out firstly by approaching the subject theoretically through the term tectonics and by setting up a model of the values a tectonic tool should encompass. Secondly the ability and validity of the model are shown by applying it to a case study of Jørn Utzon’s work on Minor Hall in Sydney Opera House - for the sake of exemplification the technical field focused on in this paper is room acoustics. Thirdly the relationship between the model of tectonics and the case will be compared and lastly a discussion about the characteristics of a tectonic tool and its implications on digital tectonic tools will be carried out.

title	Distance Collaboration. A Comparative Analysis of Tools and Procedures

summary	Besides design theory and practice, curricula of architectural students should include some experiences referring to professional situations. Among these experiences, Collaborative Design is nowadays somewhat frequent. It is normally practised by large professional studios, using expansive software which is beyond what they can afford on average. Much academic research on the topic has also been carried out often resulting in the proposition of new and too complex description models of the building object. We think that students should instead get acquainted with such a design process: an experience has been planned and carried out in our Department for the purpose of practising the possible paradigm in a more ordinary context. Its purpose was threefold. First, making the students grasp the method’s potentialities and learn the right approach. Second, testing the practical suitability of the most widely used software. Third, comparing their relative efficiency. The software we used was: Architectural Desktop, AutoCad Revit, ArchiCad for Teamwork. We focused special attention on how representing and managing restraints, since they are the main source of conflicts. This was the hardest topic to manage. The results were partly positive inasmuch as the experience showed that it could be possible to adopt the Collaborative Design paradigm which is also used in the AEC field. The drawbacks emerged from the analysis of non-dedicated software are: a relative slow process for the lack of certain specific tools; a subsequent necessity of integrating them with different communication software; the difficulty of managing hard and soft restraints. However, in the final analysis, the experience can be considered as positive.

title	Sensitive Voxel - A reactive tangible surface
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. 525-538.
summary	Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ŒµœÖ = good and Œ¨œÄœÑœâ = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner ‚Äì potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique ‚Äútouch‚Äù for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

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.

summary	It is commonly acknowledged that ‘smart’ environments, interactive architecture and ‘smart’ homes will define the next cutting edge in architectural research. Most critics agree that one of the first problems that ‘smart’ homes will help to address is that of spiraling costs of healthcare and aging-in-place. This may be true for urban settings where there is the financial feasibility for such technologies but what about rural America? It has been conclusively proven that rural America suffers from a lack of healthcare (delivery and access). Prior research (Mathew 2005) has also established that a rural home is different from an urban home. Will technologies designed for the urban home work in a rural setting? And do rural people carry the same attitudes and biases towards technology? This paper continues our research in the design of ‘smart’ rural environments. It summarizes findings from focus group studies conducted in rural communities that help us to understand attitudes of people towards ‘smart’ technology. We will use these findings to examine the feasibility of ubiquitous computing and ‘smart’ spaces in rural areas. In conclusion, we will present guidelines to help designers in the creation of technology to augment healthy aging in rural home settings.

title	DecoSketch – Towards Calligraphic Approaches to Interior Design
doi	https://doi.org/10.52842/conf.ecaade.2005.665
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 665-670
summary	Computer-Aided Design tools have long played an important role in architecture design. However, we need to go beyond direct manipulation to devise new tools that will expedite the interior design and decoration. Indeed, conventional CAD systems, while providing ever increasing functionality, do not provide equal support to the drafting and drawing tasks. This makes even the simplest drawings a complicated endeavor. Draftspeople struggle with different concepts that those learnt from their earlier days in school and have to think long and hard to translate familiar sequences of operations to commands which require navigating a dense jungle of menus. The term calligraphic interfaces was coined by us to designate a large family of applications organized around the drawing paradigm, using a digital stylus and a tablet-and-screen combination as seen most recently in Tablet PCs®. Using these, users can enter drawings in a natural manner, largely evocative of drafting techniques that were perfected for pencil-and-paper media. This paper presents a simple calligraphic interface to explore interior design literally from the ground up. The Decosketch application is a modeling and visualization tool structured around 2 _D architectural plants. Its purpose is to help architects or customers easily creating and navigating through house designs starting from the floorplan and moving to their three-dimensional representation. Moreover, both 2D and 3D representations can be independently edited, providing a natural interface that tries to adhere to well-known representations and idioms used by architects when drafting using pencil and paper.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.

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.

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.

title	Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades

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.

summary	This paper investigates the impact of Tablet PCs on the workflow in an undergraduate design studio. We examined how well the students adapted the Tablet PC into their day-to-day design work and evaluated the appropriateness of the Tablet PC as a common digital tool used in an architectural design studio. This research involved observation of student behavior during the semester and the conducting of a survey measuring various aspects of the students’ use of the computers. A more specific goal was to compare the effectiveness of the pen versus the mouse as input devices for a three-dimensional modeling task in terms of both task time and strategies. Our assumption was that a change in input mode would affect the strategies and the performance. The results of a within-subjects, repeated-measures experiment carried out to elicit differences in input devices are discussed.

summary	In this paper we describe our findings regarding the role of context in usability evaluation, particularly how the nature of the tasks can affect the users’ perception of the performance of a particular application. Our findings show a relationship between the variation in the nature of the tasks used for usability evaluation and the way in which subjects evaluate these applications afterwards using user -administered questionnaires. Our findings contradict the absolute benchmarking goal of some of these tools, and pose questions about the possibility of achieving that kind of benchmarks in software usability evaluation.

title	Learning and Designing in a Virtual Place
doi	https://doi.org/10.52842/conf.ecaade.2005.303
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 303-309
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.

title	Virtual Architecture as Representation for Creative Design Process - Through a Collaborative eDesign Studio
doi	https://doi.org/10.52842/conf.ecaade.2005.037

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.
