title	Architecture and Hyperdocument: Data Shaping Space

summary	The computer interface can't convey the hole experience of walking through a city or a building. Nevertheless, the complexity of all the aspects involved in those threedimensional spaces can be better understood through the non-linearity of the hyperdocument. Each dweller of a city and a building has many layers of relationship with both. The sequence and the extent each observer explores the space is unique. It’s not totally apprehended in a first visit. As the observer knows better that space, his experience changes. A similar situation takes place in a multimedia application. Hence, it's possible to build an analogy between the architectonic or urban structure and a hyperdocument navigation structure. We can also state that the computer is critical to create paths of architectural information through space and time. The 3D model of a city is a powerful basis to structure the hyperdocument navigation. The city can be viewed in separate parts or layers of information. One investigates the city through different aspects of its configuration and explores it in different scales and levels of detail. The images generated from this 3D model can be combined with video, photo, sound and text, organizing the information which gives form to the city. The navigation through this information, addresses the citty by its economy, housing, religion, politics, leisure, projects, symbolic buildings, and other aspects. This paper will discuss these issues through the experiments of the research done at the School of Architecture and Urbanism of the Universidade Federal do Rio de Janeiro. The research group at the "Laboratory of Urban Analysis and Digital Representation" in PROURB (Graduate Program of Urbanism) analyses the city and its buildings using CD-ROMs and websites.

title	Time sections, abstract machines

summary	conditions a time-spatial discontinuity in the urban grid, ancient walls casually discovered in a substrate of the contemporary town needs a surplus of information to be understood and interfaced with their current condition. diagrams diverse chronological stages of the urban evolution are mapped on the area, in order to read the historical stratifications as a multiplicity of signs; this abstract approach leads to consider the roman space as guided by metrics, a system of measure superimposed on the landscape, vs. medioeval spatial continuity, where more fluid relations between the same urban elements create a completely different pattern.assemblage (time sections) a surface, automatically displaced from the medioeval diagram, moves along the z axis, the historical stratification direction, intersecting in various, unpredictable, manners a series of paths; these paths start as parallels, allowing an undifferentiated access to the area, and mutate along their developing direction, intertweening and blending each other; linear openings are cut on the surface, virtually connecting the two levels by light, following the roman grid in rhythm and measure. Projected on the lateral wall, the cadence of the vertical and horizontal elements becomes a temporal diagram of the design process.movement time takes part into the process through two kinds of movement: the first one, freezed when reaches the best results, in terms of complexity, is given by the surface intersecting the tubular paths; the second one is represented by multiple routes walking on which the project can be experienced (in absence of any objective, fixed, point of view, movement becomes the only way to understand relations). Thresholds between typical architectural categories (such as inside-outside, object-landscape etc.) are blurred in favour of a more supple condition, another kind of continuity (re)appears, as a new media, between the different historical layers of the city.

title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title	Evaluation of Spatial Perception in Virtual Environments
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 145-148
summary	The 3D environments created by computers can be used as a powerful simulation tool for architecture, especially with inmersive devices, but it is necessary to know properly their spatial characteristics to use it effectively. It is also important to consider their possibilities in communication networks and their implications in contemporary architecture. For this reason, the goal of this research is to evaluate the perception of virtual architectonic spaces in relation to the perception of real architectonic spaces. This research is based on the comparison of experiences of university students in a real space (Entrance Hall of Faculty of Economy) and in the same space modeled by a computer. The evaluation considers tests with stereoscopic helmets and interactive navigation, making questionnaires to characterize the sensation of dimensions, relationships and time for an specific activity. The measuring of real and virtual spaces are made through references (furniture, textures, etc.) or by proportional relations between height, width and depth, in different patterns. The experience also reveals mental schemes to perceive the dimension of architectonic space and the orientation in a real and virtual environment. Besides, the research allows to relate the different levels of complexity and information with the understanding of real architectonic space and modeled space.

title	GIS and the Investigation of the Environmental Heritage
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 219-224
summary	This paper presents an investigation on the architectural, natural, and cultural resources in the southern part of the state of Rio Grande do Sul, according to their historical or environmental value, identifying natural and cultural elements known and valued by local communities, regardless their experts’ classification. Resources are identified by means of geographical information systems, combined with field information. The area comprises the coastal strip and the plains located in the last frontier of the Brazilian territory and the water system dominated by the lakes Patos, Mangueira and Mirim. The inventory of the environmental, sociocultural and economic heritage provides the necessary insight for issuing new development alternatives based on local resources. Research activities will include: the ellaboration of general and thematic maps, based on LANDSAT 5 [bands 3, 4 and 5] images; aerial photographs; DSG/SGE and municipal maps [scales 1:250.000, 1:50.000 and 1:25.000]; field work for the recognition of remarkable elements; interviews with residents for assessing their perception of local values; and community and institutional statements. These informations, comprising the elements valued by their architectural and urban quality, historical relevance and environmental significance, organised in a database, will provide contextual guidelines for the planning of a tourist route. This route, delineated by the preservation, recovery and use of representative local resources, valued as expressions of a native culture, evocates the initial occupation of the gaúcho territory, and may be touristically promoted as "The Gaúcho’s Way". The project also aims at showing the potential offered by GIS for identifying and evaluating specific spatial characteristics.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 157-160
summary	This work presents the study and applied assays (or simulation tests) about the ordination of urban space in the region of Lagoa da Conceição. In the region pressures placed by the growth of urban area and urban network system are in contact conflict with a fragile ecosystem, and with a sustainable development based on tourism. Analysis procedures exploited different forms of Space Syntax trying to examine effects of spatial structure in relation to movement patterns of pedestrians and vehicles. This methodology allowed the comprehension of relation between spatial configuration, transport and soil use, and reveled the interdependence and performance of built space within the restrict regional scale (Lagoa da Conceição) and the total urban structure of the island. This understanding is not limited to the present. Is also includes the study of historic urban evolution, and simulation of existing projects for the future, being an important tool to support project decision process. Consequently, the obtained results bring a new approach for the problem, which makes possible the synthesis of design proposals verifying its implications and consequences.

title	An Electronic Library for Teaching Architectural History
doi	https://doi.org/10.52842/conf.caadria.1999.335
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 335-344
summary	This research project developed an electronic library of significant buildings chosen to represent seven selected periods of Western architectural history: Egyptian (Mortuary temple of Queen Hatshepsut), Greek (Parthenon), Roman (Pantheon), Romanesque (Speyer Cathedral), Gothic (Notre Dame Cathedral), Renaissance (Tempietto), and Modern (Des Moines Art Center). All buildings were reconstructed in their original or intended forms based on plans, drawings, photographs, and historical texts. Two products were generated by this project: (1) materials to be displayed on the World Wide Web, including rendered still images for perception, movies for a visual guide, and Virtual Reality Modeling Language (VRML) models for user navigation; and (2) virtual reality (VR) models to be displayed in the C2 (an improved version of the Cave Automatic Virtual Environment or CAVE facility). The benefits of these VR models displayed on the Web and in the C2 are their easy accessibility at any time from various geographic locations and the immersive experience that enhances viewersÌ understanding of the effects of spatial proportions on form and of colors on materials.

title	Design Navigation and Construction Simulation by Virtual Reality
doi	https://doi.org/10.52842/conf.caadria.1999.031
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 31-41
summary	This paper depicts the approach of constructing a virtual reality environment for simulating architectural design and construction operations. The virtual environment is established to demonstrate the spatial performance of design and constructability of construction operations. Particularly, the functions such as navigation of construction sites, simulation of construction operations, and evaluation of construction details will be critical to construction operations. The system shell is implemented by JAVA on the web and integrated with VRML for supporting the above functions. The study focuses on the needs for the system integration and interface design. Four modes of human computer interfaces are proposed, including the user, agent, monitor, and immersion modes. Finally, this paper provides demonstration of construction simulation in an office building project to highlight the above discussion. The operations of crane towers and curtain wall installation are also studied in the construction process. In conclusion, this paper demonstrates the potential uses and limitation of virtual reality in simulation of the built environment.

title	The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source	College of Architecture, Georgia Institute of Technology
summary	Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

title	Using Immersive Virtual Reality Systems for Spatial Design in Architecture
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 307-318
summary	In the very young discipline of Virtual Reality Applications only a few reports are available about using this technology for periods longer than in experimental setups. This paper describes experiences made during four years of usage of Virtual Reality (VR) in educational training for architects. About 100 different people were working with our systems during this period. Two programs were developed at Bauhaus University with the aim of teaching students in architecture in three-dimensional sketching. An other program for free and own interfaces and environments is currently under construction and will be presented at the international computer fair "CeBit" in 1999. The first program called voxDesign is based on the metaphor of voxels. The second program, planeDesign, uses rectangualar planes to describe room-like situations. All programs force the users to design in a 1:1 scale, which means that the design and the feedback actions are coupled in an embodied way. A real walking metaphor is used for navigation. The experiences made by the students are explained too.

title	Where the Footprints Lead: Tracking down other roles for social navigation
source	Social Navigation of Information Space, eds. A. Munro, K. H. and D Benyon. London: Springer-Verlag, pp 15-34
summary	Collaborative Filtering was proposed in the early 1990's as a means of managing access to large information spaces by capturing and exploiting aspects of the experiences of previous users of the same information. Social navigation is a more general form of this style of interaction, and with the widening scope of the Internet as an information provider, systems of this sort have rapidly moved from early research prototypes to deployed services in everyday use. On the other hand, to most of the HCI community, the term social navigation" is largely synonymous with "recommendation systems": systems that match your interests to those of others and, on that basis, provide recommendations about such things as music, books, articles and films that you might enjoy. The challenge for social navigation, as an area of research and development endeavour, is to move beyond this rather limited view of the role of social navigation; and to do this, we must try to take a broader view of both our remit and our opportunities. This chapter will revisit the original motivations, and chart something of the path that recent developments have taken. Based on reflections on the original concerns that motivated research into social navigation, it will explore some new avenues of research. In particular, it will focus on two. The first is social navigation within the framework of "awareness" provisions in collaborative systems generally; and the second is the relationship of social navigation systems to spatial models and the ideas of "space" and "place" in collaborative settings. By exploring these two ideas, two related goals can be achieved. The first is to draw attention to ways in which current research into social navigation can be made relevant to other areas of research endeavour; and the second is to re-motivate the idea of "social navigation" as a fundamental model for collaboration in information-seeking."

summary	In 1995 the programming of a specialized, expert graphic software CA-TSD, began. The TSD acronym designates a graphic language derived from the theory of spatial delimitation, it systematizes all possibilities of selection and combination of flat and volumetric figures. It establishes necessary and sufficient morphic and tactic dimensions to account for all possible relationships of selection and combination. TSD proposes a syntactic reading of those formal, pure design operations underlying traditional representations. Tracings and complex configurations described by tree-hierarchical structures of simple configurations allow for a coherent syntactic analysis of the design structure of any object this will allow the construction of a pure design formula for the conscious and unconscious prefiguration operations of an artist or style in this presentation, we will use our proprietary CA-TSD software that will allow for fast verification of what's stated, including architecture and graphic design examples.

summary	This paper presents an application of swarm intelligence towards the problem of spatial configuration. The methodology classifies activities as discrete entities, which self-organise topologically through associational parameters: an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction, coupled with the problem of ‘loose’ rectangular geometric assembly. A concept model sniffingSpace (Ireland, 2009) developed in Netlogo (Willensky, 1999), which established the self-organising topological capacity of the system, is extended in Processing (Fry & Rea, 2009) to incorporate rectangular geometry towards the problem of planning architectural space.

source	Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 209-220
summary	This paper focuses on the differences in visual reasoning between a novice and an expert architectural designer during the conceptual design process. The cognitive actions of each designer while sketching were categorized into four main groups (each consisting of a number of sub-groups): physical, perceptual, functional, and conceptual. Based on this analysis, we found that the expert differs markedly from the novice in productivity in terms of the number of sketches and the number of alternative ideas. We focused on the differences between them in terms of the frequencies of cognitive actions, with the hypothesis that the difference in productivity could be attributed to the differences in some or all types of cognitive actions. Differences between the expert and the novice were found for revising features (in the subcategory of drawing actions in the physical action category), for paying attention to the relations of depicted elements (perceptual category) and for the rates of new and revisited functions (functional category). These results are discussed in terms of the types of visual reasoning processes that could be involved in expert design and the possible implications of these results if they can be demonstrated to be characteristic of expert designers generally.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 225-229
summary	We are facing a constant growth in 3D GIS, and its interaction with CAD, VR and CG, influence each other more than ever. In this context, 3D urban models can interactively assist in any step of a decision making process. Urban planners can benefit from 3D urban models in a way never thought before. PC technology , free 3D interactive viewers and VRML offer low cost implementations. Data coming from cadastral updates in Argentina are an invaluable source of digital data and building height attributes are included on that. In that way, tabular or attribute data can be linked to 3D graphic data. Geographic Information Systems can add to these 3D urban models all the benefits of attribute data plus its spatial analysis capabilities. Queries of any kind, and links to hypertext, planning documents can enhance the information provided by this "virtual world". Finally, regarding communication aspects, Interactive design and decision making can be reached in a much easier way as 3D is better than 2D. If we consider that 3D urban models can easily be browsed in VRML we have then the enormous potential of collaborative design through internet and intranet.

source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 70-80
summary	Digital media are transforming the practice and teaching of design. Information technologies offer not only better production and rendering tools but also the ability to model, manipulate, and to understand designing in new ways. This paper outlines a thirteen-step methodology used in a seminar that teaches design students how to see, think, and form space using both digital and physical media. The paper describes a systematic approach that follows the tradition of the Bauhaus principles of craftsmanship and visual perception. Precedents are drawn from the use of light, color and texture in the visual arts such as the glass collage assemblages of Albers and Moholy-Nagy’s camera-less photogram. References are also drawn from Kandinsky’s diagrammatic analysis of still life drawings and Kepes’s idea of the language of vision. The focus of the paper is how digital media and physical material can be used interchangeably as instruments in a design environment. The investigation centers on developing teaching methods for seeing, thinking and making of spatial design. A sequence of experimental exercises stimulates students’ intuition and powers of analytical observation. This systematic approach helps students explore how space can be perceived and informed by using types of media that are significantly different in their nature. The methodology explores the concerns and techniques of making and exploring space through the use of light, shadow, motion, color and transparency.

summary	Previous research (Bourdakis et al, 2012; Papasarantou et al, 2013) dealt with the problem of creating information visualisation systems capable of combining historical data of MUCIV's database and developing strategies that embed the non-spatial data in spatial models. The database was primarily designed as an experimental flexible spatio-temporal configuration of dynamic visual structures generating a variety of narrations through interaction.The attempt of producing a legible configuration driven by a number of criteria, led to the proposition of two different arrangements, namely the linear and radial array. The aim of this paper is to present the next step on the visualization after redefining both the way that thematic axes and data are visualized and arranged/scattered. Alternate configurations are investigated, based also on theoretical analysis on the conceptualization and perception of information visualization systems (Card et al 1999, Ware, 2004).

source	Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 55-68
summary	In this paper we present an approach to the qualitative representation of shape and its use. We use a qualitative coding scheme founded on landmarks in the shape. The scheme encodes a qualitative representation of angles, relative side lengths and curvatures at landmarks. We then show how such a representation can be used as a basis for reasoning about shapes using extracted shape features. We conclude with a preliminary analysis of 12 sketches of the architect Louis Kahn and show how they may be categorised based on these shape features.

summary	The solutions that allow us to attend the potential exigencies planned for a territorial administration, oblige us to establish an informatizated step, performed with a group of logical tools, supported in the corresponding data bases. This means to establish an Information System who integrates basic data to activities and own resources, being a fundamental aspect of these Systems their capacity to synthetisize the dinamic of phenomena that reflect and several parameters that are the base to analyse this. Urban and Rural real estates (cadastral register) are elementary territorial unities whose integration, complemented with structural elements of a localization area, constitute the continuous of spatial information with the most degree of resolution. Trying as "variables” all physical, economical and juridical circunstances, this continuous of information in transformed in an extraordinary and interesting product, which can be potentiate if we include the Geographic Information System (GIS) concept, resulting of adding digital cartographic data bases to attributes and literal characteristics of elements stored in alphanumeric ones. The reason of this article is to divulge the Territorial Information System set up in the Cadastral Office of the City Hall of Montevideo, based on GIS technology, emphatizying the utility it produces in so large applications as: to investigate land occupation and property distribution, to planify and optimize resources and services, to act as a fundamental support to elaborate thematic cartographies, to serve as a detailed and precise support for urbanism, service flows and territorial ordenation and all other products issued for the own implantation philosofy, constituted with an open structure where the mentioned Office isn’t the only user.

summary	The aims of research carried out at the Centre for Advanced Spatial Analysis (CASA) under the umbrella of 'Online Planning' have been two fold. Firstly, to examine how new technologies can be used for the development of an Internet based planning system and secondly, how such technologies can enhance planning education. There has been considerable overlap between these two aims when real world applications have been introduced into the education environment. Teaching methods on a number of different courses at University College London, including the MSc in Virtual Environments, the MPhil in Town Planning and the BSc in Geography, have been developed to incorporate new technologies. This article describes progress to date and suggests possible uses of Internet based technologies for the teaching of topics relating to the design of the built environment.
