title Putting It All Together: Towards a Pattern Language for Interaction Design Reports
source ACM SIGCHI Bulletin 1998 v.30 n.1 pp.17-23
summary Pattern languages are representations that have been used in architecture and urban design for about twenty years. They focus on the interaction between physical form and social behavior, and express design solutions in an understandable and generalizable form. But pattern languages are not simply set of patterns intended to be universally applied; instead, they are actually meta-languages which, when used in a particular situations, generate situated design languages. This report describes a CHI 97 workshop which explored the utility of pattern languages for interaction design. We discuss the workshop's rationale, the structure and process of the workshop, and some of the workshop's results. In particular, we describe some patterns developed as part of the workshop, and our consequent reflections on the use of patterns and pattern languages as lingua franca for interaction design. This report concludes with a bibliography on pattern languages and related matters that spans architecture, software design, and organizational design.

title CAAD System with Integrated Quantity Surveying, Energy Calculation, and LCA
source Proceedings: Green Building Challenge 98, Vancouver, Canada. Vol. 2, 68 - 75
summary In the framework of the German LEGOE project, an integrated tool is developed for computer aided architectural design (CAAD), quantity surveying (catalogue of building elements), life cycle cost calculation and estimation (construction and refurbishment), direct energy consumption (heating, hot-water, electri-city) and environmental impact assessment (mass flows and effect oriented evaluation). During the design process the architect works in his usual CAAD environment with building elements (e.g. one m2 of outer wall) which in turn are composed of detailed construction specifications, energy and mass flow coefficients and cost data. These elements are part of an independent catalogue of elements with all their relevant data. The different application programs use the same basic data and write the specific results into a project-specific database called a PDB which allows the comparison of these data to reference data from other projects. Evaluation and visualisation programs refer to the PDB only.

title The Virtual Design Team
source Communications of The ACM, Vol. 41, No. 11, November, 1998
summary The long range goal of the Virtual Design Team" (VDT) research program is to develop computational tools to analyze decision making and communication behavior and thereby to support true organizational (re)engineering. This article introduces the underlying theory, the implementation of the theory as a computational model, and results from industrial test cases. Organization theory traditionally describes organizations only at an aggregate-level, describing and predicting the behavior of entire organizations in terms of general qualitative predictions. We define and implement a "micro" theory of the structure and behavior of components of organizations, explicitly representing activities, groups of people called "actors," and organizational structure and policies for project teams. A VDT model can be "run" by a discrete event simulation. Emergent aggregate model output behaviors include the predicted time to complete a project, the total effort to do the project, and a measure of process quality. More detailed model behaviors include the time-varying backlog of individual actors and the "exceptions" associated with activities. The results are detailed and specific, so they can guide specific managerial interventions in a project team and can support sensitivity studies of the relative impact of different organizational changes. We conclude that such a theory is tractable and predictive for complex but relatively routine, project-oriented design tasks. The application for which VDT offers unique new kinds of insights is where an organization is striving to shrink time to market dramatically for a product that is similar to ones it has previously developed. Reducing time to market dramatically almost always requires that previously sequential activities are executed more concurrently. In this situation, experienced managers can still correctly identify the required activities and estimate their durations and skill requirements; but they almost always underestimate the increased workload arising from exponentially higher coordination needs and the propagation of rework between the now highly concurrent activities. The VDT framework, which explicitly models information dependency and failure propagation between concurrent activities, has proven to be far more accurate, and to incorporate a wider range of parameters, than CPM/PERT process models for these fast-paced development projects."

summary The evaluation of alternative design sets is important phase for quick design decision and new design conception, and it is repeatedly processed. To proceed design process in standard, the repetition is reduced to minimum. And design must be optimized in limited cost and time. For smooth and fast process lots of alternative design sets are provided within the limit of possibility and it must be evaluated appropriately. It's possible to evaluate alternative design sets using various media. This paper describes the characteristics of various media which have been used for evaluation of alternative design sets, and propose alternative design comparative system based on the findings of case studies.

title Informal conversation environment for collaborative concept formation
source Community Computing: Collaboration over Global Information Networks, eds. T. Ishida. John Wiley & Sons
summary This chapter focuses on facilitating the early stages of community formation. We spend a great deal of time every day in informal conversations, which are very important for the early stages of forming various kinds of communities. People engaged in conversation will not only share information, but also try to listen to and understand others, and as well as work together to find common objectives. In the early stages of forming the communities, agreement on a common concept through such a process is an essential element in the bonding of the group. Conversation environments on networked computers, e.g., via e-mail, online chat, and news groups, eliminate the spatial and temporal constraints of forming these communities but allow for the reuse of accumulated dialogs from previous interactions. Moreover, a computerized environment can directly support information sharing and mutual understanding. Conventional computerized conversation support systems, however, often force their users to follow some predetermined conversation model, prepared by designers beforehand. Thus, it can be difficult to apply these systems to informal conversations. We are developing a system called AIDE (Augmented Informative Discussion Environment) that facilitates our informal daily conversations. It does not require users to provide additional information in designated forms during a conversation, but rather it provides functionality to enhance and support the informal conversation. AIDE features three main functions: the discussion viewer, the conversationalist agent and the personal desktop. Using these functions, the participants can attain mutual understanding, crystallize ideas, and share common concepts. AIDE is considered to be not only a tool for supporting informal conversation but also useful Communityware, especially for facilitating the initial stage of community formation. This chapter first discusses a model of the group thinking process and applies it to community formation. Then, the structure of the AIDE system is presented using a few example conversations to illustrate how the AIDE system can support communication between people. AIDE displays potential as communityware.

title Possible Futures in Computer Art Generation
source International Conference on Generative Art
summary Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques   Figure 3 Trellis interpreted with "graphic ivy"   Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

source N.A. Streitz, S. Konomi, and H-J Burkhardt (eds), Cooperative Buildings: Integrating Information, Organization, and Architecture, Proceedings of CoBuild‘98, Springer, pp. 4-21
summary In this paper, we introduce the concepts of "cooperative buildings" and "roomware" and place them in the context of the integrated design of real, physical, resp. architectural spaces and virtual, resp. digital information spaces. By "roomware" we mean computer-augmented things in rooms, like doors, walls, furniture, and others. The general approach is detailed via examples from the i-LAND project where we develop several "roomware" components in order to realize an interactive information and cooperation landscape, e.g. an innovative work environment for creativity teams. We describe the current realization of i-LAND which includes an interactive electronic wall, an interactive table, computer-augmented chairs, and a mechanism for assigning physical objects as representatives of information objects in the virtual world.

summary This article analyses some of the proposals produced in the late 1970´s by the American contemporary artist Dan Graham, in which he uses technical means to investigate the audience´s perception and behavior. The questions raised highlight reciprocity phenomena and identity constructions – factors that affect our experience and behavior in contemporary cities daily life. All of these issues derive from Graham´s investigations of the main information and communication technologies (media) produced at that time, and which continue to offer reflections on current relationship between technical means and the subject – that is, his/her condition as audience, observer, spectator or user.

summary This article presents the description and evaluation of a tangible interface to facilitate a collaborative work process. It starts with the concept of ambient display, which refers to the presentation of information in space or in an object through subtle changes. After describing the developed interface, some observations from the operation of the device are presented. We conclude that ambient displays should not be used as replacements to conventional tools, but instead, as complementary elements, and that it is also important to ensure their application as a method to restore a lost balance between tangible predispositions and the center of attention.

source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 141-145
summary In a chain of "real - perceived - imagined space" the computer reduces to a uniform model of only real and imagined space. It cannot undertake man's function or it cannot build the perception model. However, perception assumes physiological perception, psychological estimation and understanding, and emotional ho-experience. For a person the seizing of space during perception is constructing temporary spatial images and their development. The communicative relations of the person with environment are established during revealing internal and external structural communications and the interior represents the message, unwrapped in space and perceived in time. The real space is formed under influence of the sum of conceptual restrictions. The character of these restrictions depends on a super idea, a type of an initial situation, character of installations and on social-cultural stereotypes of the author. Without this stage transition to real architectural object is impossible. Result of activity of an architect at this stage becomes creation hypothetical cyberspace, with its own peculiarities and laws.

title Computer animation for architectural visualisation
source University of Strathclyde
summary This thesis critically reviews the state of architectural animation, and relates this specific field to the more general motion-based representations, particularly traditional film-making techniques. It identifies key elements from traditional filmmaking and shows how these elements can improve computer-based architectural animation. The process of identification of the key elements from traditional film-making starts with a critical survey of the use of motion-based representation in local architectural practices and an empirical analysis of several architectural-based documentary films and past and present computer animations. All of the key ideas are illustrated on video by comparing real shooting clips to digital sequences focusing on production and post-production works. Some of these were implemented in two live projects ( Ministry of Finance, Malaysia and Damansara Parade ) for architects to understand the real problems and potentials in each process. These sets of illustrations expand the architect ideas to make full use of the motion-based process to improve the skill of combining architectural information in a good animation. The overall production process becomes more efficient when the motion-based footage is edited using a non-linear editing platform as it enhances the professional appearance as well as vastly saving most of the production time. The thesis concludes with specific recommendations relative to the stage at which the animation is produced. This technology can be best utilised with the right skills (a gained from film-making) and an understanding of each stage that requires a different level of input and gives a certain impact to the viewers.

source Design Studies 19, pp. 289-308
summary In this paper, we analyze the process of VRML 2.0 (Virtual Reality Modeling Language, Version 2.0) specification design for the deeper understanding of Internet-based collaboration. The VRML design process has the characteristics of being open to the public, geographically distributed, long-term, large-scale, and diverse. First, we examine the overall features of the design process by analyzing the VRML mailing list archive statistically. Secondly, we extract prototyping vocabulary (operational patterns) from the document change log. Thirdly, we analyze the process of proposing and agreeing with the PROTO node in detail. The results of analysis provide us with a guidance for facilitating innovation in the Internet-based collaboration.

title Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical study demonstrates the empirical estimation and use of the model for analysing the impacts of an expansion of floor space in the major shopping centre of a middle-sized city in The Netherlands. The results indicate that agglomeration effects as predicted by the model can have substantial impacts on the performance of retail systems. Therefore, it is argued that when incorporated in a spatial DSS, the more complex models have the potential to improve the use of these systems for impact analysis.

title Planning building design by simulating information flow
source Automation in Construction 8 (2) (1998) pp. 149-163
summary Successful project management requires the effective control of the design teams and the exchange of information between them for successful design management. This paper describes a methodology involving discrete event simulation that can help the planning and control of building design. Discipline-based information flow models of the building design process are used to define the activities of the simulation model, concentrating on the concept and schematic design stages. Factors such as task durations and resources are then allocated along with any specific constraints that are to be evaluated. The model predicts the outcomes of the specific scenario of information related events, including design schedules and resource histograms. The paper describes the development and validation of the simulation model and discusses its potential application during the planning and design phases of building projects. It is concluded that this approach could form the basis of a useful tool for design managers responsible for multidisciplinary building design work.

title Satisficing in engineering design: causes, consequences and implications for design support
source Automation in Construction 7 (2-3) (1998) pp. 213-227
summary We describe an approach to investigating design cognition which involved comparing prescriptive theories of good design practice with observations of actual design behaviour. The tenet of prescriptive theory which formed the focus of the research is the idea that designers should generate and evaluate multiple design alternatives in order to increase the chances of attaining better design solutions than might arise if they fixated upon an initial solution. Our study focused upon six professional electronic engineers attempting a novel integrated-circuit design problem. Verbal-protocol data revealed: (i) a failure to search for alternative solutions; (ii) a marked inclination to stick with early `satisficing' solution ideas even when these were showing deficiencies; and (iii) only superficial modelling and assessment of competing alternatives when such options were actually considered. We argue that while minimal solution search in design may sometimes be caused by motivational factors and working-memory limitations, its major determinant relates to inhibitory memory processes that arise subsequent to the recognition-based emergence of familiar design solutions. We conclude by exploring the implications of minimal solution search for design support, with particular reference to an agent-based indexing system which we are developing in order to facilitate the pursuit of design alternatives in engineering contexts.

title Changing trends and approaches in human and computer modelling for social housing policies
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary The paper discusses conceptual issues, goals and preliminary results of an on-going research which aims at building a Decision Support System for public housing environmental oriented maintenance and management in a city in Southern Italy, Bari. Traditional post-war Italian housing policies are compared with more recent approaches in the field, pointing out the change from quantitative, aggregated, more simple building problems and relatedapproaches to qualitative, differentiated, complex ones integrating social, economic and environmental dimensions with the aim of regenerating deteriorated residential areas. The paper claims for the need shift, both in the human and computer areas, from traditional quantitative models to new approaches able to manage also qualitative variables, temporal dynamics, emergencies, and intentionality, since they appear key aspects of the real world to be modelled. The housing estate of Bari and its needs of maintenance and management are examined, eliciting essential related knowledge using the interview technique. The clear orientation towards sustainable policies for urban regeneration, at a local, national, and Community level, is also considered. The innovative and collaborative nature of such policies and the attention to be paid to the social aspects ofthe problem require a complex DSS, integrating various kind of hypertexts, information systems and case-based fuzzy expert systems, whose main aims, functions, software and general organisation are outlined in the paper.

title Appraisal of Design Studio Methodologies
doi https://doi.org/10.52842/conf.caadria.1998.021
source CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 21-30
summary This paper investigates the relationship between different design approaches and their effectiveness in the formulation of design concepts. This inquiry will focus on the computer as the sole design and developmental tool. The research employs a short design programme, a small building with a given urban site, as its investigative vehicle. Nineteen second year students of the Mackintosh School of Architecture were monitored and their design progress evaluated. They were split into two groups: one used CAD and AEC as the only drawing and modelling tool, tutorial and review, and another used conventional tools of drawing and model making (mixed media). Structured interviews and personal observations were used as a means for data collection. Questionnaires were administered to students and their response was analysed using the statistical programme SPSS (Statistical Package for the Social Sciences). The Mann-Whitney test was used to test the Null Hypothesis that different design approaches will not produce different design outcomes. Correlation, Regression and the X2 test of independence were also employed to screen data and identify patterns of relationships.

title Reflexiones Sobre la EnseÒanza de la Arquitectura, la Informatica e Internet (Reflections on the Teaching of the Architecture, Computing and the Internet)
source II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 174-179
summary This paper proposes a reflection upon the teaching of architecture as seen from the actual practice of the profession within the context of the changes caused by the widespread use of computers and Internet in recent years. This proposal designates the present time as "semic revolution", superseding denominations like post industrial" or information revolution", emphasizing that the "mental prosthesis" created by man represents the highest degree of exploitation of his innerness as a "semic subject". A brief epistemological framework serves to lay the foundation for the concepts of imagination, creation, and design, differentiating the creator by his characteristic of requiring or not, semic mediation in order to reach his goals. The dominant use of new instruments which serve to represent and operate the "primary virtual object" giving priority to the comprehension and function of the new tool over the acquisition of information and ability to use it, is proposed when carried over to the field of application. The integration of internal networks through email strives not only to facilitate document transmission, exercises, group work, etc. but to understand the new dimension in the intellectual activities of man.

title Handling of Dynamic 2D/3-D Graphics in Narrow-Band Mobile Services
source Virtual Worlds on the Internet, IEEE Computer Society, pp. 147-156
summary The factors limiting the efficient delivery and presentation of multimedia material in the cellular environment are, among others, the low bandwidth of the transmission channel(s) and the modest capabilities of truly mobile terminals. The ACTS 1 project MObile Media and ENTertainment Services (MOMENTS) is leveraging the usage of state-of-the-art technique for the handling of vector graphics and animation contents, obtained through very low data transmission channels, in order to provide veru attractive multimedia services in that environment. This paper focuses on the achievements obtained within MOMENTS in regard to the handling of dynamic 2D/3D graphics for the projected wireless multimedia services.
