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.

title	SMAAD Surface: A tangible interface for smart material aided architectural design
doi	https://doi.org/10.52842/conf.caadria.2011.355
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 355-364
summary	In this paper, we present Smart Material Aided Architectural Design (SMAAD), the design technique to realize intuitive shape modelling with synchronizing a tangible user interface (TUI) and a 3D CAD system. To realize SMAAD, we first implemented SMAAD Surface, the TUI that imitates the free-form surface. The TUI is a fabric device, in which flex sensors and actuators (shape memory alloys) are embedded. As a designer changes the textile shape using his/her hands, its surface data will be sent to the CAD system through the sensor and a free-form surface can be created in the PC. The operation in the opposite direction is also possible, in which the CAD surface data is sent to the fabric device to dynamically change its shape. SMAAD releases architectural designers from complex GUI operations and visual programming and enables digital model creation through natural manual operations for physical models.

summary	This paper presents a framework of study of an iterative evolution of a modular component designed in an attempt to simulate material constraints and motional response with the perspective to be multiplied into a dynamic system. The main scope of this project was to investigate the process that maps a territory of possibilities, among which lies the potential architectural solution. In order to explore this field a parametric model has been developed. The simulation of the materials nature has been embedded in the algorithm on a geometry constraint basis in an attempt to simulate the behavior of the system comprised by elements in tension and torsion. A multiplication process of the module was introduced at a following stage of the research focusing on regular tessellations and circle packing on the plane. Responsive performance has been studied on a selected specimen of the evolution given a hypothetic context scenario according to which the scale of the design was set at a façade component level. The resulting responsive permeable skin was presented as a potential design solution among the successive approximations of this algorithm. Along the course of the research the parametric tools were used not only as a medium of synchronous output visualization but also as a mechanism to simulate material properties, structural constrains, environmental data, and worked as stimuli of inspiration driving the overall design process.

title	The sensitive tower: Architectural and urban design education faced with fragile metropolitan ecologies
doi	https://doi.org/10.52842/conf.ecaade.2011.581

summary	Neighborhoods that are still outside the market target can find alternative ways of re-development. Therefore, it is necessary to design architectures compatible with their fragile ecologies. This research benefits from a previous study where we tried to observe the evolution of the uses of buildings and ways of living faced with changes in environmental conditions in a given urban context. Increased automobile traffic has led to changes in the use of residential spaces whose function was gradually replaced by commercial activities. Making use of graphic-oriented interpretation of urban ambiance and landscape analysis methodology applied to the design of different floor levels, this paper aims to introduce the concept of sensitive tower defined on the basis of observations made in our post-occupancy survey as a teaching strategy for the design studio faced with the current challenges of the contemporary metropolis.

title	The role of collective intelligence in design: A protocol study of online design communication
doi	https://doi.org/10.52842/conf.caadria.2011.687
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 687-696
summary	Web-enabled collective intelligence in design invites anyone to contribute to a design process through crowd-sourcing. We use a protocol analysis method to analyse the forum data on a collective intelligence web site, studying communication among individuals who are motivated to participate in the design process. A protocol analysis allows us to compare collective intelligence in design to similar studies of individual and team design. Our analysis shows that a design process that includes collective intelligence shares processes of ideation and evaluation with individual and team design, and also includes a significant amount of social networking. Including collective intelligence in design can extend the typical design team to include potential users and amateur perspectives that direct the design to be more sensitive to users’ needs and social issues, and can serve a marketing purpose.

title	Sensitive transformations of physical territories: Digital and material procedures in designing
doi	https://doi.org/10.52842/conf.ecaade.2011.589
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.589-594
summary	This paper focuses on two issues concerning advanced architectural design techniques. The first issue has to do with design methodology and more precisely with the analysis of the fundamental ‘components’, which might compose a fragile place or environment and bear a clearly distinctive character. The second issue is related to a more architectonic agenda and concerns the consequent creation of a holistic architectural product, aiming mainly to the basic architectural concept of ‘inhabitation’. Furthermore, concerning the overall process, the idea of metabolism is becoming the central point, when referring, both to the attempt of conceiving a specific natural territory within the digital realms, and to the architectural form-finding process.

summary	The main topics of the conference are recognition, development and encouragement of virtual space design which in a consequence respect the problematic of sensitive and even fragile places of our physical and virtual surroundings. How do we define the levels of fragility either in physical or in virtual space, or in any fluid architectural endeavours? How do we respect the diversity of spatial fragility levels while introducing new design interventions? What can be defined as a (eCAADe-) sensitive / responsive / responsible design intervention? How to develop physical and virtual laboratories for sensitive / responsive / responsible design interventions? How to promote sensitive / responsive / responsible design interventions as members of eCAADe and related communities? What is the future of physical and virtual environments, requiring the most sensitive and responsible design interventions? These are just a few questions which were addressed at the eCAADe 2011 conference.

summary	In architecture various approaches have been developed do deal with changing demands on the building. The most recent development is interactive architecture. In this paper we aim to outline what interactive architecture is. First we define the type of performance behavior that an interactive building or environment has. Following, we consider the relation between the system and the user. We derive four types of relations, characterized as “perfect butler,” “partner,” “environmental,” and “wizard.” Interactive systems are composed of sensors, controllers, actuators, and materials. Various degrees of interactivity can be achieved with such systems, ranging from passive, reactive, autonomous, to agent systems. Complete with earlier discussion of design methods this provides the range of aspects that should be considered when designing interactive architecture.

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.

title	Sensing digital co-presence and digital identity: Visualizing the Bluetooth landscape of the City of Bath
doi	https://doi.org/10.52842/conf.ecaade.2011.087
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.87-92
summary	The impact of ubiquitous digital technologies on the analysis and synthesis of our urban environment is undoubtedly great. The urban topography is overlaid by an invisible, yet very tangible digital topography that is increasingly affecting our urban life. As W. J. Mitchell (Mitchell 2005) pointed out, the digital revolution has filled our world with “electronic instruments of displacement” that “embed the virtual in the physical, and weave it seamlessly into daily urban life”. The mobile phone, the most integrated mobile device is closely related to the notion of a digital identity, our personal identity on this digital space. The Bluetooth is the mainly used direct communication protocol between mobile phones today and in this scope, each device has its own unique ID, its “MAC address”. This paper investigates the potential use of recording and analysing Bluetooth enabled devices in the urban scale in understanding the interrelation between the physical and the digital topographies.

title	Designing responsive architecture: Mediating analogue and digital modelling in the studio
doi	https://doi.org/10.52842/conf.caadria.2011.155
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 155-164
summary	Prototyping digitally responsive architecture requires that architects know how to program and design electronics. Normally they don’t. The challenge for teachers is to teach these skills whilst maintaining a focus on the design potentials of responsive architecture. One method is to teach students to use Input-Output-Process (IPO) diagrams and parametric modelling as pathways into the logic of responsive architecture. The paper discusses the work of students taught this way during a semester long elective. Our analysis shows that IPO diagrams lead to reactive architecture, which matches the current technical limitations of responsive architecture. We argue that mediating analogue and digital models is an essential aspect to successful responsive architecture.

title	Turmitecture: A generic approach for autonomous topological generation
doi	https://doi.org/10.52842/conf.ecaade.2011.558
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.558-562
summary	The paper describes and discusses a generic approach for generative design by Turing Machines operating on a three-dimensionally folded surface. It is part of an on going research on concurrent cooperative design processes in architecture. During the development of systems for simplified generic interaction in spatial design, it turned out that the basic operations are applicable to be processed by non-sophisticated automata. If the spatial configuration is interpreted as the medium for an ordinary state machine, the whole system adds up to a kind of Turing Machine. Since 2D-Turing Machines are often referred to as “turmites”, and the proposed system is based on a yet three-dimensional folded, but still twodimensional surface - the automaton will be called “Turmitect”.

doi	https://doi.org/10.52842/conf.acadia.2011.x.j1c
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	This research focuses primarily on the functionality of software, specifically Rhinoceros (McNeel & Assoc.) and a few associated PlugIns (Grasshopper, Rhino Assembly), to create and control a model of a building to study the environmental effects of modulation of space. Has technology been completely utilized in addressing comfort maintenance within a dwelling space? For example, animals have a similarities based upon their surface to volume relationship, yet they are able to adjust the ratios based on a reaction to their environmental circumstances. For example, when cold, they are able to “fluff” their fur in order to minimize their surface area in comparison to an increasing “interior” volume. Historically, abilities to influence temperature change within a space have been relegated to passive air exchange systems and more recently completely active air exchange means of control. Technological advances have raised significant questions towards methods and means for this control. Through use of 3D models and simulations, the topic of climate maintenance in spatial conditions was addressed using environmental controls. Thus modulation of the interior climate as well as the space could simultaneously occur to create a radically different space of habitation. The preparation and writing of this abstract addressed various areas of the SPC requirements, which become apparent during the digestion of the paper.

summary	Designers in architectural studios, both in education and practice, have worked to integrate digital and physical media ever since they began to utilize digital tools in the design process. There are benefits of working in the digital domain as well as benefits of working physically; confronting, or seeming to confront, architects with a difficult choice. Emerging strategies for human-computer interaction such as tangible user interfaces and computer vision techniques present new possibilities for manipulating architectural designs. These technologies can help bridge between the digital and physical worlds. This paper discusses some of these technologies, analyzes several current design challenges and presents a prototype that illustrates ways in which a broader approach to human- computer interaction might resolve the problem. The ultimate goal of breaking down the boundary between the digital and physical design platforms is to create a unified domain of "continuous thought" for all design activities.

title	Race track modeler. Developing an Iterative Design Workflow Combining a Game Engine and Parametric Design
doi	https://doi.org/10.52842/conf.acadia.2011.x.v2b
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	This paper documents the continuing development and testing of a novel digital work flow established and implemented for the design and redevelopment of formula one racing tracks. The Race Track Modeler (RTM) tool uses a game engine to simulate driving around proposed track designs. Performance data from the simulation is combined with real data acquired from analysis of vehicle mounted accident data recorders (ADRs). The output of the tool is a graphical representation of simulated stopping positions of vehicles that have lost control and left the track. This information directly informs the design of motor racing facilities; the zoning of spectator facilities, position and specification of crash barriers (if required), and surface material selection for the run-off zones (the area where vehicles are expected to stop after losing control and leaving the track). The RTM can suggest further design changes to the track geometry which are then fed back into the game engine. The project involves methods of binding analysis of design directly to geometry together with input from interactive controls. The RTM has been developed and tested during the redevelopment of Silverstone race track in the United Kingdom (figure 1) this paper documents the current state of the tool and concludes with proposed future developments.

title	A Computer Aided Design Model for Climate Responsive Dwelling Roof
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. 315-332.
summary	Computer-Aided Design models have generated new possibilities in the sustainable design of buildings. Computer models assisting different aspects of architectural design have been developed and used for several decades. A review of contributions of computing to architectural design is given by Gero. Most of the conventional simulation computer programs do not actively support design development and optimization, specially at the formative design stages. It is well established that most decisions that affect comfort and building energy use occur during the formative design stages of the project. Furthermore, the efforts required to implement those decisions at the beginning of the design process are small compared to the effort that would be necessary later on in the design process. Therefore, if sustainable design issues are going to receive an appropriate level of consideration at the beginning of the design process, they must be presented in a way which is useful to the architect and fits with other things the architect is considering at that time. Design is seen as a problem-solving process of searching through a space of design solutions. The process of finding a solution to a design problem involves, identifying one or more objectives, making design decisions based on the objectives, predicting and evaluating the performance to find the acceptable decisions. Each of these activities can be performed inside or outside the formal model. In designing a roof, an architect or building designer has to make many decisions on the materials. The arrangement of these materials determines the aesthetic appearance of the roof and the house. Other considerations that affect the choice of roofing materials are thermal performance, rain, fire protection, cost, availability and maintenance. Recyclability of materials, hazardous materials, life-cycle expectancy, solutions, and design options as they relate to the environment also need to be considered. Consequently, the design of roof has become quite a complex and multifaceted problem. The principal need is for a direct design aid which can generate feasible solutions and tradeoff performance in conflicting requirements and prescribe the optimum solution. This paper presents a conceptual Computer Aided Design model for dwelling roof. It is based on generation and optimization paradigms of Computer Aided Design; which is diametrically opposite to conventional simulation. The design of roof (design goal) can be defined in terms of design objective as "control radiant and conduction heat." This objective must be satisfied to achieve the design goal. The performance variables, such as roof ceiling surface temperature or new thermal performance index (TPI*) must acquire values within certain ranges which will satisfy the objective. Given the required inputs, this computer model automatically generates prescriptive quantitative information to design roof to achieve optimum thermal comfort in warm humid tropics. The model first generates feasible solutions based on the decision rules; next it evaluates the thermal performance of the roof taking into account design variables related to the building‚Äôs roof and finally it applies numerical optimization techniques to automatically determine the optimum design variables, which achieve the best thermal performance. The rational and methodology used to develop the proposed model is outlined and the implementation of model is described with examples for climatic and technological contexts of India and Australia.

summary	Digital tools are currently being used in design schools across the country. This paradigm in both education and practice of architecture is continually changing the profession, from the way in which design is conceived, represented, documented, and fabricated. Parametric design can be defined as a series of questions to establish the variables of a design and a computational definition that can be utilized to facilitate a variety of solutions. Parametric thinking is a way of relating tangible and intangible systems into a design proposal removed from digital tool specificity and establishes relationships between properties within a system. It asks architects to start with the design parameters and not preconceived or predetermined design solutions.

title	Irregular Vertex Editing and Pattern Design on Mesh

summary	This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex which is connected with fewer or greater less or more edges than regular vertices on a mesh object. Irregular vertices create problems with further surface rationalization, as well as structural analysis and constructability of the surface. Geometry created using other tools can also be remeshed upon import. Using the developed tool, the user is able to identify irregular vertices, interactively change the type, and then move or remove these irregular vertices. Additionally, a computational tool to make various design patterns on the mesh after the topology has been edited is also developed. The workflow is illustrated step by step in the pipeline. The advantages and disadvantages of editing mesh topology on architectural geometry design including the limitations are discussed at the end.

summary	Today’s spatial formations are based on tectonics and forms of physical environments in terms of dealing with the envisioned and finished configurations. However, as a result of media and information technologies, digital space brings out a new interpretation and aspect to the architectural space within the new concepts of space, time and reality. By digital space, users can imagine, produce, share, and store their perception and experiences in a new kind of territory which is based on data and information. The incremental and ever-changing needs of user and inclusively improving environments are the most common impacts of this information age that give rise to the importance of information rather than material. Stratified space is a combination of the physical space and digital space. Within this combination, we suggest a new concept of architectural space which will respond the dynamic, unpredictable and ever-changing needs of its users and environmental conditions.
