title Travelpost: Media Access via Geographic and Temporal Information
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The versatility with which digital media such as images, sounds, and video clips can be presented, combined with the ease of sharing and accessing digital media through the internet, creates opportunities for displaying media in new and useful ways. Associating meta-data (additional information about the media) with digital media extends these opportunities by enabling the media to organize itself. For example, a collection of media items that “knows” where and when they were recorded can position themselves on a map and a timeline. With these visual tools a person can better understand the location and time of a specific media item, as well as its spatial and temporal relationship to the other items. This paper presents an internet application that implements these ideas. Travelpost (http://www.dandelion.org/travelpost), is a system for browsing media recorded during a persons travels. A map, a timeline, and a regular web browser window offer three interrelated browsers to the user. This allows the user to investigate the entire data-set, in this case a travelers journey, from a geographic, temporal, or media specific view.

title Integrating Energy Design Into Caad Tools: Theoretical Limits and Potentials
source CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 323-340

summary The study is part of a research aims to establish theoretical grounds essential for the development of user efficient design tools for energy-conscious architectural design, based on theories in human factors of intelligent interfaces, problem solving, and architectural design. It starts by reviewing the shortcomings of the current energy design tools, from both architectural design and human factor points of view. It discusses the issues of energy integration with design from three different points of view: architectural, problem-solving, and human factors. It evaluates theoretically the potentials and limitations of the current approaches and technologies in artificial intelligence toward achieving the notion "integrating energy design knowledge into the design process" in practice and education based on research in the area of problem solving and human factors and usability concerns. The study considers the user interface model that is based on the cognitive approach and can be implemented by the hierarchical structure and the object-oriented model, as a promising direction for future development. That is because this model regards the user as the center of the design tool. However, there are still limitations that require extensive research in both theoretical and implementation directions. At the end, the study concludes by discussing the important points for future research.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title Generation and visualization of 3D-city and facility models using CyberCity Modeler (CC-Modeler)
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The efficient generation of data for 3-D city models and their handling in Spatial Information Systems has become feasible. The derivation of this data from aerial and terrestrial images with semi-automated techniques constitutes the most powerful tool currently available to fulfill this task. Semi-automated object extraction has become a viable concept for the generation of 3-D city models. CyberCity-Modeler (CC-Modeler) has been developed with the aim of creating not only buildings, but also other objects pertaining to a city model efficiently and with a high degree of flexibility concerning the level of detail. In its commercial implementation, CCModeler has been confronted with a number of user requirements which needed to be observed. This led to some extensions in functionality, which are addressed in this paper: Geometrical regularization of buildings, editing functions for topology adjustment, integration of facades and other vertical walls and modeling of overhanging roofs. These extensions of the original concept make CyberCity-Modeler an even more powerful tool for 3-D city modeling.

title Enhancing Architectural Communication with Gaming Engines

summary This paper makes a case for exploring the feasibility of utilizing the advanced graphics and sound systems of contemporary gaming engines to promote architecturally relevant work. Gaming engines, while developed largely for the PC entertainment industry, have vast potential for application in architecture. This paper will explore the depth of this potential and will outline work demonstrating the advantages and the limitations of this technology. The supporting research and observations examine the technology and reveal its potential usefulness as an instructional or depictive authoring tool. Game engines were selected that had appropriate graphical prowess, but were customizable as to allow the removal of game-specific features (to create a “professional” user interface). Projects were authored that expressed complex building details using the engine for visual depiction. The details, which included constructional components, structural assemblies, or simple design nuances, were modeled with 3D geometry and realistically textured and lighted. The game engine allowed one user or many remote simultaneous users in the virtual environment to interactively explore the presentation in real time. Scripts were developed to encourage end-users to interactively disassemble or reassemble building components as desired. Audile and/or text-based information regarding the assembly sequence were provided by exploiting the game interface features. Furthermore, interactive object scaling was provided to facilitate analysis of component relationships.

summary The purpose of this work is to design a spatially-aware tangible interface for interactive 3D visualization. We explore an integrated platform whereby digital representations are integrated with physical artifacts. Our work provides a means to display separated perspective views of a design on multiple-projection physical planes. Users can directly interact with the physical planes to view digital information. By coupling physical artifacts with digital representations, the view of 3D information is mapped to physical space. Our work reduces the cognitive load on novice designers, and enhances the user's capability of understanding the relationships between multiple design representations.

summary Working with big models requires a good balance between the technical requirements of the model and the technical requirements of the user. Although every virtual model, whether it is 2d, 3d or 4d, may be regarded as a particular form of a general data base, it is clear that is not, at the present time, a very flexible data base. It does not behave like a relational data base that can be inspected in a flexible way. On the contrary, it has a rigid structure, a hierarchical structure that is well suited for performance but is badly suited for navigating through the data and gathering derived information. These are well known disadvantages and advantages, related to the evolution of the data base software that has moved, in the last 30 years, from a hierarchical to a relational structure. These considerations are relevant for any kind of architectural or engineering model. But are particularly pertinent in the case of the model of a city where everything must have its place, and should relate properly with other parts of the model, be susceptible of further modifications and be able to receive new information. These and other related issues have been encountered and developed during the construction of several models at our Laboratory at the ETS Architecture of Barcelona. Our paper explains the main decisions we had to take during the course of these works with special emphasis on those aspects related with the organization of different kind of data in a unified whole that had to be sent to other professionals and had to be, for that reason, organized in a clear and comprehensible way for its further development.

title EO-PLAN-GIS Operational earth observation applications involving user communities on national and European level
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The joint GeoVille/ARC Seibersdorf project EO-Plan-GIS has the objective of deriving Earth Observation (EO)/Geographic Information System (GIS) products for public and private customers (i.e. Austrian state governments and digital mapping industry). Representatives of three state administrations (i.e. Carynthia, Upper Austria and Vorarlberg) and of Tele Atlas (a commercial enterprise in the production of digital road databases) have been actively involved in the project activities. The major focus of the project is on the automated differentiation of built-up areas and the derivation of land use/cover data for both the state governments and Tele Atlas, as well as on the update and upgrade of the Tele Atlas road network. Using GIS methods, the EO-derived base data will be adapted to serve the individual user needs (i.e. Geographic State Information Systems and Tele Atlas MultiNet). EO-Plan-GIS was initiated by the Austrian Ministry of Transport, Innovation and Technology as a national initiative within theframework of the current GMES (Global Monitoring for Environment and Security) activities of ESA and the EU. It delivers inputs into the following GMES domains:• European Regional Monitoring, Subtopic A: Land cover change in Europe, characterisation of land cover changes (1950 –2000) in the EU with particular emphasis on landscapes and urban areas.• Horizontal Support Action – Information Management Tools & the Development of a European Spatial Data“Infostructure”.

title From CAD to iAD - A Prototype Simulation of the Internet-based Steel Construction Consulting for Architects
source CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 919-936
doi https://doi.org/10.52842/conf.caadria.2003.919
summary Information technology has become so powerful and interactive that what is conventionally called CAD might evolve into iAD (Internet Aided Design). For Internet applications in the AEC (Architecture, Engineering and Construction) industry, most of the efforts and applications have been concentrated on project management and collaboration, while in the area of design and engineering consulting, limited progress has been made. Even with some of this success, contemporary development has not changed the nature of the fragmentation of the AEC industry. Based on previous research surveys (Zhou & Krawczyk 2001) of the development of Internet applications in the AEC industry and the proposal of a conceptual model of Internet-based engineering consulting in architecture, this research will apply these theories and concepts into a specified area of steel construction consulting for architects. The first phase of this research will define the content and scope of steel construction consulting and the potential Internet application. Second, a proposed solid working model is developed covering organizational structure, user network, services provided and technology. In the third phase (as this paper presented), a prototype simulation is used to apply the concepts and methodology in a preliminary design application to demonstrate how this Internet-based consulting model would work.

summary The conference logo is a bird’s eye view of spiral stairs that join and separate – an homage to the famous double spiral staircase in Graz, a tourist attraction of this city and a must-see for any architecturally minded visitor. Carved out of limestone, the medieval construction of the original is a daring feat of masonry as well as a symbolic gesture. The design speaks of separation and reconciliation: The paths of two people that climb the double spiral stairs separate and then meet again at each platform. The relationship between architectural design and the growing digital repertoire of tools and possibilities seems to undergo similar cycles of attraction and rejection: enthusiasm about digital innovations – whether in Virtual Reality, Augmented Reality, Energy Design, Robotic Fabrication, the many Dimensions of BIM or, as right now, in AI and Machine Learning – is typically followed by a certain disillusionment and a realization that the promises were somewhat overblown. But a turn away from these digital innovations can only be temporary. In our call for papers we refer to the first and second ‘digital turns’, a term Mario Carpo coined. Yes, it’s a bit of a pun, but you could indeed see these digital turns in our logo as well. Carpo would probably agree that design and the digital have become inseparably intertwined. While they may be circling in different directions, an innovative rejoinder is always just around the corner. The theme of the conference asked participants to re-consider the relationship between Design and the Digital. The notion of a cycle is already present in the syllable “re”. Indeed, 20 years earlier, in 2003, we held an ECAADE conference in Graz simply under the title “Digital Design” and our re-using – or is it re-cycling? – the theme can be seen as the completion of one of those cycles described above: One level up, we meet again, we’ve come full circle. The question of the relationship between Design and the Digital is still in flux, still worthy of renewed consideration. There is a historical notion implicit in the theme. To reconsider something, one needs to take a step back, to look into the past as well as into the future. Indeed, at this conference we wanted to take a longer view, something not done often enough in the fast-paced world of digital technology. Carefully considering one’s past can be a source of inspiration. In fact, the double spiral stair that inspired our conference logo also inspired many architects through the ages. Konrad Wachsmann, for example, is said to have come up with his famous Grapevine assembly system based on this double spiral stair and its intricate joinery. More recently, Rem Koolhaas deemed the double spiral staircase in Graz important enough to include a detailed model of it in his “elements of architecture” exhibition at the Venice Biennale in 2014. Our interpretation of the stair is a typically digital one, you might say. First of all: it’s a rendering of a virtual model; it only exists inside a computer. Secondly, this virtual model isn’t true to the original. Instead, it does what the digital has made so easy to do: it exaggerates. Where the original has just two spiral stairs that separate and join, our model consists of countless stairs that are joined in this way. We see only a part of the model, but the stairs appear to continue in all directions. The implication is of an endless field of spiral stairs. As the 3D model was generated with a parametric script, it would be very easy to change all parameters of it – including the number of stairs that make it up. Everyone at this conference is familiar with the concept of parametric design: it makes generating models of seemingly endless amounts of connected spiral stairs really easy. Although, of course, if we’re too literal about the term ‘endless’, generating our stair model will eventually crash even the most advanced computers. We know that, too. – That's another truth about the Digital: it makes a promise of infinity, which, in the end, it can’t keep. And even if it could: what’s the point of just adding more of the same: more variations, more options, more possible ways to get lost? Doesn’t the original double spiral staircase contain all those derivatives already? Don’t we know that ‘more’ isn’t necessarily better? In the original double spiral stair the happy end is guaranteed: the lovers’ paths meet at the top as well as when they exit the building. Therefore, the stair is also colloquially known as the Busserlstiege (the kissing stair) or the Versöhnungsstiege (reconciliation stair). In our digitally enhanced version, this outcome is no longer clear: we can choose between multiple directions at each level and we risk losing sight of the one we were with. This is also emblematic of our field of research. eCAADe was founded to promote “good practice and sharing information in relation to the use of computers in research and education in architecture and related professions” (see ecaade.org). That may have seemed a straightforward proposition forty years ago, when the association was founded. A look at the breadth and depth of research topics presented and discussed at this conference (and as a consequence in this book, for which you’re reading the editorial) shows how the field has developed over these forty years. There are sessions on Digital Design Education, on Digital Fabrication, on Virtual Reality, on Virtual Heritage, on Generative Design and Machine Learning, on Digital Cities, on Simulation and Digital Twins, on BIM, on Sustainability, on Circular Design, on Design Theory and on Digital Design Experimentations. We hope you will find what you’re looking for in this book and at the conference – and maybe even more than that: surprising turns and happy encounters between Design and the Digital.

title A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source 7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

title Integrated 4d Cad and Construction Safety Planning Information for a Better Safety Management

doi https://doi.org/10.52842/conf.caadria.2003.891
summary Safety is an important element of project successes. In the conventional project management, safety planning, as a function, is separated from other functions, such as planning/scheduling function. This separation creates difficulties for engineers to analyze what, when, why and where a safety measure is needed to prevent accidents in a construction activity. Another problem occurs due to the conventional practice of representing project designs using two-dimensional (2D) drawings. In this practice, a user (e.g. an engineer) has to convert the 2D drawings into three-dimensional (3D) mental pictures, and this is a tedious task. If only converting this 2D drawing is a tedious task, combining these 2D drawings with safety planning creates more difficult tasks. In order to address the problems, this paper discusses our research in integrating construction scheduling and safety planning in a 4D environment.

title Digital Design - Research and Practice

summary The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title DEVELOPING A VIRTUAL REALITY-BASED METHODOLOGY FOR PEOPLE WITH DEMENTIA: A FEASIBILITY STUDY.
source Journal of CyberPsychology and Behavior, Vol6, Number6, 2003.
summary The aim of this study was to examine the feasibility of virtual reality (VR) technology for use by persons with dementia (PWD). Data were obtained directly from six PWD regarding their experiences with a virtual environment (VE) of a large outdoor park. A user-centered method was developed to assess: (a) presence; (b) user inputs; (c) display quality; (d) simulation fidelity; and (e) overall system usability. The extent to which PWD could perform four functional activities in the VE was also investigated (e.g., mailing a letter). In addition, physical and psychological well-being of PWD while interacting with the VE was assessed objectively by recording heart rate during the VR sessions and subjectively with discrete questionnaire items and real-time prompts. Symptom profiles associated with simulator sickness were assessed with an adapted version of the Simulator Sickness Questionnaire. The study found that PWD to some extent experienced presence; perceived that objects were realistic and moved naturally; generally felt in control of the interaction; and demonstrated little difficulty using a joystick for navigation. The study also demonstrated that VR is an appropriate medium for assessing functional behavior within the context of an ecologically valid VE. PWD did not experience any significant increase in symptoms associated with simulator sickness, or detriments to their psychological and physical well-being. These findings demonstrated that it is feasible to work in VEs with PWD.

title Look Who's Suggesting
source International Journal of Design Computing, 2003, Volume 6
summary During design architects do not only sketch, they combine different kinds of information and representations. The combination of text, image, sketch and/or draft can provoke new associations that keep the design process going. The sketchbook presented here enables architects to use all representations simultaneously, so as to fully exploit their cross-fertilisation. More importantly, it steadily makes suggestions for continuing development of design ideas. These suggestions can take the form of words that are semantically related to the users’ ideas, or of images showing how other architects have developed related ideas into built artefacts. To this end, the sketchbook captures all information the architect/user puts ‘on paper’ and forwards it to a design idea recorder/interpreter called Idea Space System (ISS). In trying to understand the user’s ideas, ISS places all elements captured into a gigantic network, as if part of the frame of reference is made explicit. In the network nodes are words, sketches or images, while links represent relations of various origins. The semantic relations that ISS identifies are shown to the user. At the same time, words are processed as search criteria in DYNAMO, a growing architectural case base, to detect and display design projects that exemplify related ideas. Through the explicit links between early ideas and concrete design cases, the sketchbook acts as a permanent source of inspiration, while stimulating both architects’ creativity and their awareness of the downstream implications of design ideas.

title The Level of Knowledge of CAD Objects within the Building Information Model
source Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 173-177
doi https://doi.org/10.52842/conf.acadia.2003.173
summary The first generation of CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful graphics symbols. These entities only represented the geometrical properties of the architectural elements. With the present emerging generation of CAD systems, a new concept shifts a drawing-based model into a Building Information Model with the potential of modeling true architectural objects. Theoretically, these CAD objects will provide all related data to the designer describing the geometry, as well as any related data associated with how the object is actually used. The knowledge required to support an object should have structure to it. Different levels of knowledge need to be included, such as the geometrical information, which should be flexible enough to accommodate any type of shape and modification while keeping the object’s integrity as a unit and maintaining its relations to other objects. The CAD object concept, as remarkable as it is, might also have potential problems. It has some implications over the design process, as well as the architectural profession itself.

title Tangible Design Media: Toward An Interactive CAD Platform
source International Journal of Architectural Computing vol. 1 - no. 2
summary This paper presents an interactive CAD platform that uses a tangible user interface to visualize and modify 3D geometry through manipulation of physical artifacts.The tangible user interface attempts to move away from the commonly used non-intuitive desktop CAD environment to a 3D CAD environment that more accurately mimics traditional desktop drawing and pin-up situations. An important goal is to reduce the apparent complexity of CAD user interfaces and reduce the cognitive load on designers. Opportunities for extending tangible design media toward an interactive CAD platform are discussed.

title Diseño de información. Disciplina decisiva frente la sobreinformación en Internet (Design of information. A decisive discipline against information overload in Internet)
source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary The designers of information in front of the panorama of it overflows, explosion and saturation of information in Internet, have the responsibility of being guides in this "infoxicación" sea (Piscitelli, 2000), contributing to the administration of the information, synthesizing its complexity and elaborating a message that is materialized in an interface that balances form and function, appealing to an aesthetic and technological dose combined with the appropriate usability, where the access, the distribution and the understanding of the information, is solved and in consequence, the metabolism of the same one and its later assimilation, is facilited.
