summary In previous papers the authors have described low cost, pragmatic interaction devices for architectural virtual environments, in particular the bike as a means of locomotion around a virtual urban environment. They have also been involved in work on portable systems for city navigation and representation, based around a personal digital assistant running pseudo 3d models of the city with an associated information database. This paper describes work that develops the two ideas of familiar real world interaction device and portability to produce a portable system for interaction with architectural urban models.

title Back to the Future: Performative Architecture
source International Journal of Architectural Computing vol. 2 - no. 1
summary The paper addresses performative architecture as an emerging design paradigm in which building performance, broadly understood, becomes a guiding design principle. It traces the origins of this approach to design to Tom Maver's visionary work in early seventies, discusses the inadequacy of existing building performance simulation tools in conceptual design, and proposes the development of software that can provide dynamic processes of formation based on specific performance objectives.

title Analyzing Pedestrian Movement in Mataf Using GPSand GIS to Support Space Redesign
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary Evaluating the use of architectural and urban spaces is an important issue for architects and urban designers who wish to enhance space usability. Space usability is crucial in crowded spaces such as Mataf areas. Millions of people come to the city of Makkah, Saudi Arabia every year to perform Hajj (Islamic Pilgrimage) and Umrah. A cornerstone of Hajj and Umrah spirituals is to perform Tawaf, which is the circumambulation of the Ka'bah in the center of the Holy Mosque in Makkah. The areas of performing Tawaf (called Mataf) become very crowded during Hajj and the last ten days of Ramadan. This paper demonstrates how we utilized Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to analyze pedestrian movement while performing Tawaf. During the Hajj of 1424 H (2004 in the Georgian Calendar), several GPS devices were used to collect pedestrian movement coordinates at specific time intervals. Computer software for tracking analysis is used to visualize and analyze the pattern of pedestrian movement in Tawaf. The software allows users to view temporal data, which can be set up with past time windows for historical data analysis. The findings of this research show levels of service and flow rates throughout different zones and times of Mataf. They indicate the most critical zones and times for Tawaf during Hajj. They also visually demonstrate the track pattern of pedestrian movement at different locations in the Tawaf area. The paper concludes with some redesign recommendations to remove obstacles and facilitate pedestrian movement in Tawaf. The approach described in this paper can be implemented in architectural and urban design space modifications to improve pedestrian movement in open spaces.

title CAAD's Seven Arguable Virtues
source International Journal of Architectural Computing vol. 2 - no. 1
summary In 1995 Maver proposed seven deadly sins for CAAD as the prelude to a critical discussion on the principles, methods and practices of the field. In an attempt to return to this discussion, in this paper these sins are linked to the seven deadly sins and the complementary seven heavenly virtues. The analysis of computational processes into a theoretic, an algorithmic and an implementational framework provides a framework for the positioning of sins and possible or already attained virtues in CAAD.

title COMPUTATIONAL PROCESSES OF A HALL CAD MODELISATION FOR ACOUSTIC SIMULATION ACCORDING TO ACCEPTED GEOMETRY FORMAT VIA ACOUSTIC SOFTWARE
source 1st International Conference “From Scientific Computing to Computational Engineering” (IC-SCCE), 8-10 September 2004, Athens, Greece
summary The acoustic computational simulation presents many advantages but at the same time there are some limits corresponding, among others, to the modelisation of the hall geometry. The integrated modelers of geometry of the halls in the acoustic simulation software are based especially on the programming code modelisation via text editors of coordinate points and not on the graphical modelisation, as the CAD software is. In cases of complex architectural shapes of halls, the majority of the acoustic simulation software imperatively needs to import a model from a CAD software. However, the modelisation of the geometry of the hall must take into account several criteria in order to run in an acoustic simulation software, and optimize the calculation results, such as the plane surfaces, the limited number of surfaces in some cases, the elimination of the unnecessary elements, the accepted geometry model format, etc. This paper explains the description and the particularities of three different modelisation processes of the Architectural School Amphitheater of Bordeaux in a CAD system in order to be adequate for acoustic simulation via acoustic software, such as ASCII, dxf and normals orientation model formats. It also presents computer automatization aspects of these processes integrated in a plate-form adaptable to a CAD system named “CAD-Acoustic.” These modelisation processes can also be a helpful tool during the architectural conception of the acoustic hall.

summary (pdf file in greek)- With the aid of the acoustic simulation plate-form named « CAD-Acoustic » which is developed in the context of PhD and adapted on the AutoCAD system, this paper presents the halls acoustic results (RT60) of Elmia (Sweden) and Opera of Bordeaux (France) in relation to acoustic measurements and results of other acoustic simulation software (Odeon, Epidaure). In parallel, it presents geometrical simulations of the modelised halls’ acoustic behavior, such as the 3D reflections of the acoustic rays from selected surface, the 3D view of the materials’ arrangements through surfaces’ coloring, the measurement of the selected absorbing / reflecting surfaces in m2 and the individual or massive absorption coefficients’ assignment to the surfaces. Finally, with the aid of « CAD-Acoustic » the acoustic results are compared in a graphic manner in relation to the ideal acoustic rates, a presentation which is a kind of an “ architectural translation of the acoustic results” taking into account several architectural elements.

title Space is the Machine, with a Ghost Inside
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 157-173
summary The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.

summary The project deals with supplementation of fine art components to the newly designed square in front of the main railway station and their integration into the public space to provide a good system functioning in the contemporary ground-floor level. Several students of Faculty of Architecture, Slovak University of Technology in Bratislava, have elaborated this idea under the leadership of B. Kubinsky with the technical support of P. Kardos during the years 2001 and 2002. The supplementation had been planned in two parts: first each student has designed his own object of art and created the model of his piece. Then, in the second part, the quality and relevance of each object was verified by the spatial endoscope in the laboratory of P. Kardos .

title Application of Genetic Algorithms to Establish Flooding Evacuation Path Model in Metropolitan Area

summary This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.

title Frames, Knowledge and Media - An investigative Study of Frame Systems within Computer and Paper Supported Collaborative Design Process
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 410-417
summary Can media foster better performance of problem framing? Problem framing contributes to successful design learning. Minsky classified this activity into four types of frames. In collaborative design, media as external representation assist designers to converse their ideas with others and themselves. This paper explores the effects of rich and lean media on the context of frame systems within computer supported and paper supported collaborative design environments. Through conducting laboratory experiment we find that different media indeed can influence the distribution of frames along the whole design sessions. To investigate this phenomenon some possible reasons related to theory are explored, shedding light on our future study on design education.

title The Dual Heritage of CAAD Research
source International Journal of Architectural Computing vol. 2 - no. 1
summary The development of research in computer aided architectural design has evolved in the context of architectural design. A review of Tom Maver's work is undertaken from the perspective of his shortest paper, CAAD's Seven Deadly Sins. In that paper cautions were given to researchers. Here these cautions are interpreted in the context of the dual heritage of our field in science and creative arts. An examination of Tom Maver's own work suggests that these sins are counterbalanced by a like number of virtues and it is suggested that these are demonstrated in the corpus of his work and the community he has fostered.

title REASONS TO STOP TEACHING CAAD
source Mao-Lin Chiu (ed), Digital design education, Garden City Publishing, Taipei 2003, ISBN 9867705203
summary Computers are a problem. They are expensive, even if the prices have dropped dramatically and promise to continue dropping. They do not look after themselves but demand considerable attention – we have to hire computer specialists to ensure they talk to each other, staff are required to make sure software is installed and to fix things when it no longer works. Learning to use them is tedious; skills have to be developed to master several idiosyncratic software systems. The hardware and software regularly malfunction. It is faster to draw a line by hand than with software. Students already have enough trouble learning how to stop a window leaking or ensure a fire escape route will protect people in time of trouble, why make them learn all these other things. We should stop teaching CAAD. Although technological and economic issues are very real and not to be dismissed lightly, the real problems of teaching CAAD are not these. The real issues we need to address is how we teach and, behind that, why we teach. This paper explores the what and why.

title Problem Framing in Multiple Settings
source International Journal of Architectural Computing vol. 2 - no. 4, 444-460
summary This study offers an insight to architectural students' problem framing activities using digital and paper media. The role of problem framing in design processes and its contribution to design learning has been studied by others. Here, we investigate the effects of media on framing activities. Laboratory experiments were conducted to investigate problem framing under three settings, namely online co-located, online remote and paper-based co-located. Student pairs were asked to spend forty minutes in solving collaboratively a wicked design problem. The results show that problem framing activities are significantly different in the online remote setting compared to those in the two co-located settings. We find more density of framing activities happened in the online remote setting than in the other two settings while there is no significant difference between online co-located and paper-based colocated settings.

summary This research makes use of a cognitive study to explore a mechanism for associating ideas in a brainstorming session. Firstly, we propose a linking model integrating three principles of idea association (similarity, contrast and contiguity) with two processes of case-based reasoning (retrieval and adaptation). For identifying the types and mechanisms of linkages within the linking model, a design experiment and its protocol analysis was conducted. Finally, a framework for case-based reasoning to support idea association called Dynamic Idea-Maps (DIM) is proposed, and its components and mechanisms are elucidated.

Based on this framework, we implement an information structure for users to interact with information space interactively, which includes information nodes, hyperlinks and interplays through i-Room system (Chang and Lai, 2003). Furthermore, the information structure of representation is also tested and reevaluated in representing ten historical significant civic buildings in Taiwan.

summary Idea association is an important behavior to generate diverse ideas during brainstorming. Through three linking principles (similarity, contrast and contiguity), idea association involves a dynamic linking process between ideas and design cases. Based on the knowledge representation issue-concept-form proposed by Oxman (1993), three interactive patterns between ideas and design cases are investigated. Finally, some computational mechanisms for supporting the linkage of idea association are discussed.
