summary	In recent years there has been a demand that local residents take part in the planning of environmental designs from the initial stages. On the issue of understanding the local environment, it is desirable to accumulate and share information and to enable it to be reused. To this end, attention has been focused on the cellular phone which can provide position information and picture information in addition to serving as a tool of general communication. For several years now it has been increasingly common for cellular phones to be equipped with an E-mail function, a web browsing function, a camera function, a GPS function, etc. Using such cellular phones, it will become possible to quickly accumulate local information with detailed picture information and position information. On the other hand, it is desirable to look at and understand an environment interactively from various points of view from the initial stage of a project. For that purpose, examination using 3D space which makes real-time simulation possible is required. In this research, using a cellular phone with a GPS camera, scene image data is collected with the aim of constructing a local scene evaluation system which can perform a picture display using a 3D space model.

title	Mapping the City in Movement: The Car as an A/V Apparatus
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 397-400
summary	“…our experience of the city, and hence our response to architecture, is almost exclusively conducted through the medium of the automobile: the car defines our space whether we are driving, being driven or avoiding being driven over. The car has been an integral part of metropolitan life for so long that it has become part of the urban fabric.” Jonathan Bell, Carchitecture. This DVD presents a series of audio/video mappings of the city in movement - an organizational condition which is derived from our car culture, a culture in movement. In these studies the digital audio/video camera, a device which allows us to explicitly record movement and change in time, is used as an investigative tool and as an extension of our bodies in order to observe, capture and measure otherwise imperceptible moments of our moving and fast paced experience of place. The projects are from a seminar/studio entitled A/V Mappings and Notations. This research looks at the merging of moving image and more conventional drawing to create maps which read physical and ephemeral conditions of place in an experiential and analytical manner. The importance of The Car as an A/V Apparatus studies is that they allow us to uncover characteristics of place that are particular to the infrastructure of our car cities and most importantly to the experience of inhabiting the transitory spaces of these cities in movement. The projects which will be presented extend the human body into the city via the car as an audio/video apparatus, an instrument for reading and measuring the city in movement. The documents are choreographed as sections through the city in which the section cut (the line drawn) is the trajectory of driving/drawing. In the making of these full-scale life size drawings, cameras are mounted to the car prior to driving. The location(s) of camera(s) are determined by the specifics of each investigation. What is choreographed is the set up of the car as an audio/video apparatus and of the trajectory of driving. The apparatus itself, the body/car/camera, in its trajectory captures, studies, measures, draws/drives. This as an extension of the human body allows us to detach ourselves from the dominance of our vision and to more objectively discover aspects of place as related to our movement and corporeal experience and otherwise hidden from our perception. In addition and more importantly as body/car/camera, the apparatus captures the city at the scale of driving (corpor/car) a scale which expands our body into the scale of a larger space of great distances, movements, speeds, and durations. The discoveries that these mappings reveal inform us of the potential for more specifically intervening in these cities with proposals which engage these two drastically different yet intricately connected scales.

title	Immersive Mappings in Audio/Video and Installation
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 451-455
summary	Architecture, spaces, cities… are not static but rather dynamic and ever changing entities. The city, which is composed of activities, interactions, patterns of use, changes, is dynamic and temporal. As James Corner states in The Agency of Mapping: Speculation, Critique and Invention; “The experiences of space cannot be separated from the events that happen in it” (1). Mapping practices, which have evolved from the experiential to the pictorial to the mathematical and abstract, more often have failed to combine these various important aspects which describe a place. Michel de Certeau in Walking the City argues that the plan-like image of a city as seen from above is nothing else but a “viewpoint… a picture, whose condition of possibility is an oblivion and a misunderstanding of practices”. He argues for the experience of wandering through the city as a “process of appropriation of the topographical system” (2). In my work and the work of my students, the audio/video camera has been employed as a medium with which to combine the various characteristics that make up place. It has been important to be both immersed as well as removed, to be both realistic and abstract, to be picturesque and analytical. In addition, we have experimented with the merging of two vocabularies: that of architectural drawing and that of moving image as a way to rediscover both vocabularies and as a way to achieve readings of place that are both qualitative and quantitative. In this essay, various mappings and notations of cities done through the exploitation of the audio/video camera as a mapping medium will be introduced.

title	Feature clusters for online recognition of graphic units in drawings

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.

title	Optimization in the Balance between the Production Effort of E-learning Tutorials and their related Learning Outcome
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 122-126
summary	This paper provides evidence on the level of media richness that may be cost effective in the development of e-learning tutorials for teaching and learning computer visualization techniques. For such a purpose the author provides an analysis of low-cost / high-impact media rich products, the effort and cost required in their development and the measurement of related learning outcomes. Circa twenty years of R&D of multimedia and hypermedia applications for instruction have demonstrated the benefits of communicating relevant information to learners using engaging media. Based on this evidence, this paper assumes that due to the cognitive style of design students, the instructional packages for learning computer techniques for design visualization that are rich in media content, tend to be more effective. Available visualization technologies make the development of e-learning tutorials feasible and apparently the logical way to implement our instructional packages. However the question in the development of e-learning tutorials becomes a more strategic one when we are called to reach a level of optimization between producing a package with a basic standard, namely; text & still-graphic based tutorials, or a state-of-the-art package that is based on video demonstrations (more than enough?) that can accommodate the students’ learning requirements and also our production costs. The costs include the human resources (instructor, producers, assistants and others) and the material resources (hardware and software, copies, and others) involved in the creation of the e-learning tutorials. The key question is: What is good enough, and what is clearly superfluous? In order to confirm our hypothesis and propose a relevant balance between media richness and learning effectiveness, this paper describes an experiment in the use of two different levels of media richness as used to deliver instructions on the production of computer animations for design visualization. The students recruited for this experiment were fairly familiarized with the use of 3D modeling concepts and software, but had no previous knowledge of the techniques included in the tutorials; in specific; camera animation procedures. The students, separated in two groups, used one of the two methods; then they proceeded to apply their newly acquired skills in the production of an animation without using the help of any external means. The assessment of results was based on the quality of the final product and the students’ performance in the recall of the production procedures. Finally an interview with the students was conducted on their perception of what was accomplished from a metacognitive point of view. The results were processed in order to establish comparisons between the different levels of achievement and the students’ metacognitive assessment of learning. These results have helped us to create a clear set of recommendations for the production of e-learning tutorials and their conditions for implementation. The most beneficial characteristics of the two tested methods in relation to type of information, choice of media, method of information delivery, flexibility of production/editorial tools,! and overall cost of production, will be transferred into the development of a more refined product to be tested at larger scale.

title	Space, Events and Urban Performance
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 333-336
summary	This report investigates different kinds of Urban Performance in Thames Path, South Bank of Thames River. Urban Performance is defined here as the expression or manifestation of different social groups in the city space regarding the appropriation of a specific place for its spatial practices. The Urban Performances are intrinsic to the cultural expression of the city and revealed through the spatial experience of both performer and spectator. The aim of this paper is to shed light on different kind of urban performances and how are they linked to spatial and syntactic properties of space. This topic is intrinsic in the space syntax theory due its fundamental relation between spatiality and human activity. The research method used were, direct observations by static snapshots and traces (related with human movement) and a survey of potential attractors, active facades and path widths. The results were overlaid with spatial analysis in terms of performers isovists and syntactic analysis through visibility graph. The findings show a strong relation between performers’ use of space and visibility in the urban area, and a high influence of the cultural attractions and public services that works as movement attractors. The discussion is developed through the research findings and theories of spatial experience putting forward varied interpretations related with the research topic and the selected site. The report concludes that the urban performances in Thames path is determined by the human co presence in the space, due to this strategic points chosen along the path by the performers are strongly related with the visual connections in the system. Furthermore, the attractors play an important role shaping the spatial experience and urban character of the studied area.

title	A Constraint-Based Building Bulk Design Support
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary	We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

title	Entornos Virtuales y su interconectividad en la WEB para la planificación urbana [Virtual Environments and their Interconnectivity in the Web for the Urban Planning]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 350-354
summary	Virtual Environments and their Interconnectivity in the Web for the Urban Planning. This work presents the creation of virtual environments based on the urban space of the Plaza Baralt in Maracaibo, Venezuela; in defined historical moments as study scenarios, using autonomous virtual agents. The selection of the scenarios is based in the analysis of the place in the present, and the study of multimedia material of the period 1920-2006. The main objective is developing virtual environments, incorporating the interconnectivity in the Web into a multi-user system, for the urban planning. Methodologically, it's divided into the following phases: 1) Data search; 2) Study of the social, cultural, religious and economical activities of the square; 3) Analysis of the urban space; 4) Virtual reconstruction of the scenarios in the present and in the period between 1900 - 1927; 5) VRML exporting ; 6) Characters' animation; 7) Integration of the models into a multi-user system; and 8) Web event for the presentation of the results.

summary	The focus in our elective course for Master Students of Architecture is the following: in parallel to a more traditional way of analysing urban structures, how can the application of multimedia technology, networking and the integration of interactive computer applications lead to a different approach? The objective of our teaching and research project is to find out in what ways urban structure and specific features of a city can be represented by interactive interfaces and the use of CNC technology. Our attitude is based on small-scale approach: the sum of these microanalyses gives us the broader picture, the system or mechanisms of the city. We do not dive into the city but emerge from it. This reflection leads to a new understanding in the organisation of complex urban structures, highlighting and revealing different connections and relationships, thus giving a different final image.

summary	To make whole one image on screens that is generated by many computers and synchronization among computers, there is a need for a network software environment for multi-projector display system. Although the development costs increase for parallel programming for multi-projector display system, there is a possibility that the program cannot be executed at an enough speed since the network bandwidth might become a bottleneck. There are some software environments for that kind of multi-projector display system like Chromium that is latest version of WireGL (Humphreys, 2001&2002). WireGL is a kind of Client-Server Model, which one rendering server sends the data of rendering to many computers. While it can use the application without modification of source, it requires heavy network traffics. The other type of operating software is VR Juggler (Cruz-Neira, 2002), and CAVE Library that is a kind of Master-Slave Model. In the Master-Slave Model, every computer has same application programs to render the image that only keep the synchronization of rendering and events. But, these programs require a specialized skill and knowledge to modify the source of program for the certain rendering PC-Cluster system.

title	Approach to Design Behavioural Models for Traffic Network Users - Choice of transport mode
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 151-166
summary	Our research work concerns the development of a multimodal urban traffic simulator designed to be a tool of decision-making aid similar to a game wherein the user-player can test different scenarios by immersion in a 3D virtual city. Our approach is based on the activity-based model and the multi-agent technology. The implemented result is a hybrid simulator connecting numerical simulation and behavioural aspects coming from real data. This paper is focused on two points: firstly, we introduce how a final user (the traffic regulator) instantiates and assembles components so as to model a city and its urban traffic network; secondly, we present the use of Dempster-Shafer theory in the context of discrete choice modelling. Our approach manipulates input variables in order to test realistic representations of behaviours of agent categories in a decision-making process. The traffic modelling is based on a questionnaire elaborated from standard arrays of Taguchi. The significant variables and interactions are determined with the analysis of variance which suggests a reduced model describing the behaviour of a particular social category. The belief theory is used to take into account the doubt of some respondents as well as for the preferences redistribution if the number of alternatives changes. The effects of external traffic conditions are also quantified to choose a 'robust' alternative and to use the agents' memory.

summary	In this paper, we make the assumption that a shape modelling process can rely on the application of a set of morphological operators to initial shapes. We refer to several researches which have attempted to identify such operators. We also attempt to validate this design approach through the analysis of some buildings. A design system based on the combination of these operators could enable the designer to quickly explore a great number of spatial solutions.

summary	The relative contributions of five variables (Stereoscopy, screen size, field of view, level of realism and level of detail) of virtual reality systems on spatial comprehension and presence are evaluated here. Using a variable-centered approach instead of an object-centric view as its theoretical basis, the contributions of these five variables and their two-way interactions are estimated through a 25-1 fractional factorial experiment (screening design) of resolution V with 84 subjects. The experiment design, procedure, measures used, creation of scales and indices, results of statistical analysis, their meaning and agenda for future research are elaborated.

title	Digital Rectified Imagery: a survey method for design and conservation projects
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Faced with the need for understanding the physical context of the projects that come under their jurisdiction, architects, urban designers, and conservationists strive to secure congruent information. Practicing professionals are not set to carry out the collecting of information themselves. As information “users,” they reach out to information “providers,” including surveyors, photogrammetrists, and GIS specialists, to secure needed information. Information providers employ a gamut of methods to survey and document design project contexts, including land surveying techniques, stereophotogrammetry, rectified imagery, laser scanning, and GIS. This study deals with digital rectified imagery (DRI) only and is aimed at creating an awareness of the method characteristics in the minds of the information users toward taking advantage of available DRI documentation opportunities offered by the information providers. As part of the methodology for this study, the authors have selected a subject building, captured a number of images through a digital camera, and processed the images using image processing software. The significance of this study resides in enabling the information users to understand RDI and to tap on its potential for consummating design, planning, and conservation projects.

summary	This paper presents a study of the comparison of tangible user interfaces and graphical user interfaces on designers’ cognitive actions. We conducted individual design experiments using the protocol analysis method. The results reveal that designers using the tabletop system with 3D blocks reasoned more about spatial relationships among 3D objects, while the designers using the keyboard and mouse reasoned more about individual 3D objects.

summary	The impact of collaborative design in virtual environments on the behaviour of designers depends on the nature of the design task and the resources available to the designers. By introducing new technology, we can identify the kinds of positive impacts that should be integrated, and the kinds of negative impacts that should be eliminated, in order to improve the collaborative design environment. We studied designers collaborating in three environments: (1) face-to-face with their current design and communication tools (pen and paper), (2) a shared remote drawing system (Group Board) with synchronous voice and video conference and (3) a 3D virtual world with synchronous voice and video conference. Collaborative design sessions of 5 architect pairs were video recorded. They respectively worked on separate design briefs in the three different design settings. Protocol analysis was used to study and compare collaborative design behaviour.

title	An Internet Survey for an Activity-Based Model - An urban transportation analysis integrated in a G.I.S. environment

summary	The current research deals with the development of an Activity-Based Multi Agent System fully implemented in a G.I.S. framework and applied to the case study of the historical centre of Pisa. The objective is to create a simulation tool for Pisa population transfers in order to verify how transport demand varies because of interventions on traffic plan (e.g. creating urban areas subject to a toll access for vehicles), or on public transport lines, or on new activities location (e.g. supermarkets, public services etc.). Three different parts of the System have been simultaneously carried out: the first concerns a population sample survey, the second deals with geographical data structuring and the last one, still in elaboration progress, tests the model reliability to estract and implement behavioural rules. The results obtained till now show how the Database itself, containing temporal data about agents activities (extracted by the population sample questionnaire) and urban services the city offers, already represents an important instrument to support decision making process.

title	Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.
