summary The study of a cyberuniversity derives from an analogy between real urban space and its virtual "substitution". It represents an attempt to balance some views, which seems to be contrary, exclusive, but they are just parts of the same wholeness. Especially the notion of a cyber society is lately considered such an exaggeration, that it is possible to forget the meaning of a real life experience and interactions, which are already threatened. One should contribute to the awarness that is used in such a comparison, it is "just" an analogy, not a real similarity. At the same time it is possible to point out some limitations of a cyberspace and indicate a more realistic view of the meaning of cyber communities. Awarness of the development processes could help to find a balance between reality and virtuality, using cyberfacilities not to destroy us (our identity) but to improve the quality of our (real) life.

summary In this paper we present an outline of a newly started project to develop a tool which connects BIM to a manufacturing technique like 3D printing. First we will look some promising manufacturing techniques. We will design a small dwelling and export it into a BIM, from which we will extract our data to generate the path the nozzle has to follow. The chosen path is constrained by the material properties, the design and speed of the nozzle. To validate the system we develop a small VR tool in which we mimic a manufacturing tool.

title Visual Design Thinking in the Design Process as Impacted by Digital Media

summary Exploring design ideas, through two dimensional and three dimensional forms, is the basis of design exploration and visual design thinking during the design process. Imagining how drawings and models (be it manual or digital) will be presented in reality is the essence of visual design thinking. By the beginning of the 20th Century, architecture has become more three dimensional in design exploration and in representation. This transition to three dimensions makes the processes of visual design thinking more related to digital media. The nature of media, utilized by architects, affects design-exploration processes. The research investigates both the processes of visual design thinking and the interrelation between visual design thinking and digital media, in order to shed more light on how digital media should be introduced to students of architecture.

summary Some researchers have tried to answer the question: do we need to think differently while designing in terms of the digital environment? This methodological question leads to another question: what is the range of this difference, if there is one? This research investigates the range of changes in how architects conduct and develop the initial design within the digital environment. The role offered by the digital environment in visual design thinking during conceptual designing through shaping: concepts, forms, and design methods, is identified and explored.

summary Responsive architecture is one of the growing areas of computational design that is not getting adequate attention in CAAD curricula. A pedagogical approach to designing responsive systems requires more than the typical knowledge, tools or skill sets in architectural design studios. This paper presents a framework for integrating responsive and kinetic systems in the architectural design studio. The framework builds on findings of two design studios conducted at The American University in Cairo, Egypt. In both studios, students were asked to design elements of responsive architecture that work towards the development of their projects. The paper demonstrates the process and outcomes of both studios. It then demonstrates how concepts of integrated project delivery are incorporated to propose a framework that engages students in designing, fabricating and operating responsive systems in different phases of the design process. A discussion follows regarding dynamics of design studio in light of the proposed framework.

summary This paper describes the process of designing a prototype for a soft responsive system for a kinetic building facade. The prototype uses lightweight materials and mechanisms to generate a building facade skin that is both soft (less dependent on hard mechanical systems) and responsive (dynamically and simultaneously adapting to spatial and environmental conditions). By combining concepts stemming from both tensegrity structures and folding mechanisms, we develop a prototype that changes dynamically to produce varying facade patterns and perforations based on sensor-network data and feedback. We use radiation sensors and shape memory alloys to control the prototype mechanism and allow for the required parametric adaptation. Based on the data from the radiation sensors, the lengths of the shape memory alloys are altered using electric wires and are parametrically linked to the input data. The transformation in the resulting overall surface is directly linked to the desired levels of daylighting and solar exposure. We conclude with directions for future research, including full scale testing, advanced simulation, and multi-objective optimization.

title A Computational Method for Tracking the Hygroscopic Motion of Wood to develop Adaptive Architectural Skins

summary Low-cost programmable materials such as wood have been utilized to replace mechanical actuators of adaptive architectural skins. Although research investigated ways to understand the hygroscopic response of wood to variations in humidity levels, there are still no clear methods developed to track and analyze such response. This paper introduces a computational method to analyze, track and store the hygroscopic response of wood through image analysis and continuous tracking of angular measurements in relation to time. This is done through a computational closed loop that links the smart material interface (SMI) representing hygroscopic response with a digital and tangible interface comprising a Flex sensor, Arduino kit, and FireFly plugin. Results show no significant difference between the proposed sensing mechanism and conventional image analysis tracking systems. Using the described method, acquiring real-time data can be utilized to develop learning mechanisms and predict the controlled motion of programmable material for adaptive architectural skins.

summary In this paper we introduce mineR- a tool that integrates statistical data analysis inside the parametric design environment Grasshopper. We first discuss how the integration of statistical data analysis would improve the parametric modelling workflow. Then we present the statistical programming language R. Thereafter, we show how mineR is built to facilitate the use of R in the context of parametric modelling. Using two example cases, we demonstrate the potential of implementing mineR in the context of urban design and analysis. Finally, we discuss the results and possible further developments.

summary When thinking about the future vision of a city, having in mind recent development in digital technologies and digital design tools we are inclined to expect new building structures which incorporate this technology to better help us manage the complexity of life, and to simplify our daily lives and tasks. The idea behind this research paper lies in design of such structures, which could be put inside an urban context and engage in creating a built environment that can add more to the quality of life. For us Interactive architecture is architecture that is responsive, flexible, changing, always moving and adapting to the needs of today. The world is becoming more dynamic, society is constantly changing and the new needs it develops need to be accommodated. As a result architecture has to follow. Spaces have to become more adaptive, responsive and nature concerned, while having the ability for metamorphosis, flexibility and interactivity. Taken as a starting point of this idea is a specific module from graduation project in 2014 "The Unexpected city", where it was possible to test out first ideas about interactive and flexible objects in an urban environment.

summary The rise in robotics is not only changing fabrication research in architecture but increasingly providing opportunities for animating the materiality of architecture, offering responsive, performative and adaptive design possibilities for the built environment. A fundamental challenge with robotics is its suitability to safe, and comfortable use in proximity to the human body. Here we present the preliminary results of the Roamniture Project, a hybrid approach to developing kinetic architecture based on a combination of rigid and soft body dynamics.

summary Typological design implies extensive knowledge of building types in order to design a building belonging to a building type. It facilitates the design process, which can be considered us a sequence of decisions. The paper gives an outline of a new approach in a course teaching typological knowledge through the medium of Knowledge-Based Systems programming. It demonstrates how Knowledge-Based Systems offer an appropriate structure for analysing the knowledge required to implement typological design. The class consists of third-year undergraduate students with no extensive previous programming experience. The implementation language is AutoLISP which operates in the AutoCAD environment. The building type used in the course is the office building. in order to become acquainted with both building type and programming in AutoLISP, information and instructions have been gathered and prestructured, including a worked out analysis and AutoLISP code. Office plans are generated through use of the Knowledge-Based System. They are encoded in the form of frames. At the end of the course the students will have learned the basics of Knowledge-Based Systems, have been introduced to programming these systems, have analysed and reflected upon the design process, and gained insight into a specific building type.

source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 169-177
summary Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

title An Agent Framework for Recognition of Graphic Units in Drawings

summary Architects use graphic conventions in their drawings that have meaningful content to the design task. In previous work, such well-defined sets of graphic entities have been identified and defined. These sets are called graphic units. In this paper, we discuss how graphic unit recognition in drawings can take place using a multi-agent systems approach. This approach seems promising as singular agents may specialize in graphic unit-recognition, and multi-agent systems can address problems of ambiguity through negotiation mechanisms. We present an agent framework for this purpose, how it connects to the theory of graphic units, and how agents for recognizing graphic units are defined. The paper ends with a discussion of current findings and future work.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 269-274
summary CAD tools are increasing their expressive and geometric power to enable a design process in which the computer model can be used throughout the whole design process for realizing the design. Such a process, in which other media such as physical scale models or drawings are no longer required by necessity to facilitate the design process, can be considered a digital design process. Rather than proposing that such a process is ideal – drawings and scale models should not be discarded – we feel that when taken as a starting point, the digital design process raises a number of new challenges to architectural design that deserve attention. These challenges concern the basic activities in design: exploration of the problem space, creating preliminary solutions, understanding consequences of design decisions, and so forth. In this paper we take the concrete design case of a graduation project that was developed from the start solely in CAD. We identify a number of key issues in that process such as continuous modeling, the model as design, continuous pliability, localized focus, and postponed decision. These issues not only have a technical, CAD-related aspect, but also are connected to architectural design. Most of these aspects are subject of contemporary debate in architectural design. On this basis, we can indicate where CAD is making a potential difference in architectural design.

summary In this paper we outline a strategy of structured reflection to improve reflection by students in a course on the implication of CAAD, design theory, and design methodology. Earlier editions of the course showed that students often did not evolve their learning beyond a checklist level. Reflection is an important mechanism to improve learning from design situations. After a consideration of the main approaches to design reflection, we take up Schön’s notion of reflection and provide support for structured reflection in CAAD education, based on earlier experiences with structured question lists in a civil engineering course. Findings after the first year’s run show a deeper level of reflection on a more elaborate level.

title The Desk-Cave - A Low-Cost Versatile Virtual Reality Design and Research Setup Between Desktop and CAVE
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 142-147
summary Virtual Reality has become an almost ubiquitous technology in many applications, but it has seen limited success in design support. Reasons for this seem to lie in lack of easily available tools, high threshold for non-programmers, and high cost of equipment. In this paper we describe a Virtual Reality environment that is developed at Design Systems called the Desk-Cave. The Desk-Cave is a low-cost VR setup that combines principles of a CAVE system with a work desk. Architecture students with no specific training in VR technology use the Desk-Cave in design projects both in the early stage and the final presentation stage. The system allows quick transfer to the Desk-Cave and architectural evaluation of design proposals.

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 7-16
summary The paper discusses the differences between teaching CAAD by using standard software ("off-the-shelf"-software) and teaching the principles of CAAD ("principles-teaching"). The paper distinguishes four kinds of application for design systems in education: social systems, professional systems, educational systems, and innovative systems. The paper furthermore proposes to distinguish between computational issues and architectural issues relative to design systems. It appears that there is not a principled distinction between software-teaching and principles-teaching when it comes to computational issues of design systems. However, when the architectural content of CAAD systems is concerned, then principles of CAAD systems seem to be more appropriate for teaching. The paper presents work on generic representations as a specific case. Generic representations can be used to teach one particular kind of architectural content of design systems. The paper ends with conclusions.

summary This paper presents a recently finished course of eight weeks where CAAD skills, design methodology, and architectural theory are combined to discuss possible perspectives on the use of the computer in design, and its influence on architecture. In the course, three contemporary architects were studied; Peter Eisenman, Ben van Berkel, and Greg Lynn. Each was discussed on aspects of ontology (which are the elements of discourse), design method (design process and organization of the process), and the use of the computer (techniques and approaches). These were linked with design theory, architectural theory, and CAD-theory. The reflection on the work of the architects resulted in a number of design methods for each architect. The design methods were adapted to the available technologies in the university as well as to the scope of the exercise, since the period of eight weeks for an exercise cannot compete with design processes in practice that take many participants and much time. The students then applied the design methods to a design task: student housing and an exhibition pavilion on the campus area of the university. The task was so devised, that students could focus on either architectural or urban design level with one of the design methods. Also, the choice of architects and accompanying design methods was made in such a way that students with low, medium, and advanced computer skills could take part in the course and exercise. In a workshop held at the Czech Technical University (CVUT) in Prague, the same procedure was used in a one-week period for a different design task, but in an otherwise almost identical setting with respect to the CAAD software used. The methods and material were easily transferred to the other setting. The students were able to cope with the task and produced surprising results in the short time span available. The paper will provide an overview of the course, discuss the pedagogical implications of the work, and discuss how this particular work can be generalized to incorporate other architects and approaches.

summary Automated recognition of sketch drawings can provide the means for a natural interface between the designer and a design support system. Sketch drawing recognition is knowledge-intensive in the sense that the system must know what to look for in a drawing. In earlier work, we identified 24 different types of representations, termed graphic units. For recognition of graphic units we combine a multi-agent approach and online recognition. Each agent is specialised for one graphic unit. It continuously parses the online input stream for stroke features that fall within its scope. When an agent-specific threshold is reached, the agent puts a claim. Each agent has a specific cluster of features that can be viewed as distributed over a decision tree. The activation pattern of feature clusters over the decision tree is an indication which graphic unit is likely to be identified by the system. In this paper, we present the exhaustive set of features for agents and a binary decision tree over which the features are distributed.

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.
