title Adaptive hypermedia
source User modelling and User-Adapted Interaction, volume 11, pp. 87-110, Kluwer
summary Hypertext/hypermedia systems and user-model-based adaptive systems in the areas of learning and information retrieval have for a long time been considered as two mutually exclusive approaches to information access. Adaptive systems tailor information to the user and may guide the user in the information space to present the most relevant material, taking into account a model of the user's goals, interests and preferences. Hypermedia systems, on the other hand, are `user neutral': they provide the user with the tools and the freedom to explore an information space by browsing through a complex network of information nodes. Adaptive hypertext and hypermedia systems attempt to bridge the gap between these two approaches. Adaptation of hypermedia systems to each individual user is increasingly needed. With the growing size, complexity and heterogeneity of current hypermedia systems, such as the World Wide Web, it becomes virtually impossible to impose guidelines on authors concerning the overall organization of hypermedia information. The networks therefore become so complex and unstructured that the existing navigational tools are no longer powerful enough to provide orientation on where to search for the needed information. It is also not possible to identify appropriate pre-defined paths or subnets for users with certain goals and knowledge backgrounds since the user community of hypermedia systems is usually quite inhomogeneous. This is particularly true for Web-based applications which are expected to be used by a much greater variety of users than any earlier standalone application. A possible remedy for the negative effects of the traditional `one-size-fits-all' approach in the development of hypermedia systems is to equip them with the ability to adapt to the needs of their individual users. A possible way of achieving adaptivity is by modeling the users and tailoring the system's interactions to their goals, tasks and interests. In this sense, the notion of adaptive hypertext/hypermedia comes naturally to denote a hypertext or hypermedia system which reflects some features of the user and/or characteristics of his system usage in a user model, and utilizes this model in order to adapt various behavioral aspects of the system to the user. This book is the first comprehensive publication on adaptive hypertext and hypermedia. It is oriented towards researchers and practitioners in the fields of hypertext and hypermedia, information systems, andpersonalized systems. It is also an important resource for the numerous developers of Web-based applications. The design decisions, adaptation methods, and experience presented in this book are a unique source of ideas and techniques for developing more usable and more intelligent Web-based systems suitable for a great variety of users. The practitioners will find it important that many of the adaptation techniques presented in this book have proved to be efficient and are ready to be used in various applications.

summary Addressing the subject of Case-Based Reasoning (CBR) in architectural design, we present a Web-based design assistant for student- and professional architects called DYNAMO. Its main objective is to initiate and nurture the life-long process of learning from (design) experience as suggested by CBR’s cognitive model. Rather than adopting this model as such, DYNAMO extrapolates it beyond the individual by stimulating and intensifying several modes of interaction. One mode – the focus of this paper – concerns the interaction between the realm of design education and the world of practice. DYNAMO offers a platform for exchanging design efforts and insights, in the form of cases, between both parties, which perfectly chimes with the current tendency towards life-long learning and continuing education. Just like our university advises graduates to ‘Take a maintenance contract with your degree’, architecture schools may encourage recently qualified architects to subscribe to DYNAMO. To what extent the tool can fulfill this role of maintenance contract is discussed at the end of the paper, which reports on how DYNAMO was used and appreciated by professional architects at different levels of expertise.

summary The Internet has in just a few years radically changed the technical foundation for how the supply chain of scientific publications and teaching materials functions. As researchers we can with just a few clicks find a significant part of all the information we need for free on the World Wide Web. As teachers we can find huge amounts of digital material which can be downloaded or linked from the web and included in presentation overheads, or hyperlinked as reading material. Yet the business and legal (copyright issues) infrastructure has hardly changed and presents a barrier to innovation and reengineering of the overall process. This paper describes some recent trends in how the Internet influences these two fields (publication of research resuls and production of teaching material) as well as related developments in the organisation of software develop-ment, and discusses them both from an economic and philosophical perspective.

summary In the last 18 months, students from the Institute for Industrial Building Production (ifib) have undertaken six design projects as so-called Netzentwurf (“Net- Design”) studios in collaboration with different universities in Europe. These studios have used a web-based collaboration platform established at an independent web site and use didactical methods for web based design collaboration established over the past four years at ifib. A total of some 500 students have been involved in these projects and all have used the common platform to carry out their presentation and communication work.

summary The development of the Virtual Reality Modelling Language (VRML) for the Internet has resulted in the emergence of a multiplicity of 3D web sites. The metaphor used by these sites varies enormously from virtual galleries to virtual cities and style varies from abstract to reality. Additionally these worlds are populated by virtual objects, some having reactive or interactive properties, including movement, audio, video, databases, artificial intelligence etc. Perhaps the most stimulating embodiment of these new environments are those that offer the participant the opportunity to meet and communicate with other visitors exploring the same virtual space/world. The Glasgow Directory is an established 3D web space, with around 10,000 visitors per year. The model represents approximayely 10,000 properties in the city and is populated by contextual information on its culture and socio-economic topography. This paper will describe the background to this VR space, and suggest a set of design criteria for successfully deploying multi-user software within this and similar environments. These criteria will take into account lessons learned by 'observing' and analysing how participants interact with the existing system under different conditions and also what benefits they perceive on entering the environment via the multi-user interface. These recommendations will hopefully be applicable to a wide spectrum of internet virtual environment builders and users.

summary Computer-aided architectural design research and teaching has a long history going back to the 1960s. However, the last ten years has seen a dramatic upsurge in activity brought about by factors such as the increasing use of CAD systems in practice, the increase in computer literacy generally and perhaps, equally importantly, the development and widespread use of the World Wide Web. The CAADRIA conference series provides a forum for the presentation and exchange of ideas and experiences in CAAD, particularly focussed on Asian research and teaching. This, the proceedings of the Sixth International Conference on Computer-Aided Architectural Design Research and Teaching in Asia, presents 57 (31 long and 26 short) papers. The 57 papers were selected from the 114 submissions following a blind review of extended abstracts. Each submission was reviewed by two referees and the decision to accept was based on a committee's assessment of all the submissions. The final papers were assessed to determine if the reviewers' recommendations had been complied with. The authors of the selected papers represent 17 countries, making this an international as well as an Asian conference.

title Designing Virtual Architecture: From Place to User Centred Design
source International Journal of Design Computing, vol 4
summary The internet and the World Wide Web have entered our daily lives and networked environments have become an important extension of our living environment. The effect of this is the definition of the place around us is expanded. Through the use of an architectural metaphor, we are now considering the use of place as a basis for organising our virtual environment and therefore raises the need for principles and models for designing virtual architecture. Virtual Architecture, or as others call it virtual worlds or cyberspace, interprets, represents and designs the World Wide Web as a place, which supports an extended range of online individual and collaborative activities. Different platforms currently in use for designing and implementing virtual architecture aim at providing 3D virtual worlds as the design outcome. This common aim has an emphasis on the visualisation of virtual architecture, resulting in an emphasis on the design of 3D place-like forms. In this article we present a range of development issues that lead us to change the focus from the design of place-centric to user-centric virtual architecture.

title Architecture and the Internet: Designing Places in Cyberspace
doi https://doi.org/10.52842/conf.acadia.2001.230
source Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 230-241
summary Cyberspace, as the information space is called, has become accessible in the past decade through the World Wide Web. And although it can only be experienced through the mediation of computers, it is quickly becoming an alternative stage for everyday economic, cultural, and other human activities. As such, there is a potential and a need to design it according to place-like principles. Making places for human inhabitation is, of course, what architects, landscape architects, town planners, and interior designers have been doing in physical space for thousands of years. It is curious, therefore, that Cyberspace designers have not capitalized on the theories, experiences, and practices that have been guiding physical place-making. Rather, they have adopted the woefully inadequate ‘document metaphor’: instead of ‘web-places’ we find ‘web-pages.’ 3D environments that closely mimic physical space are not much better suited for making Cyber-places: they are, by and large, devoid of essential characteristics that make a ‘place’ different from a mere ‘space,’ and only rarely are they sensitive to, and take advantage of, the peculiarities of Cyberspace. We believe that this state of affairs is temporary, characteristic of early adoption stages of new technologies. As the Web matures, and as it assumes more fully its role as a space rather than as means of communication, there will be a growing need to design it according to place-making principles rather than document-making ones. By looking at physical architecture as a case study and metaphor for organizing space into meaningful places, this paper explores the possibility of organizing Cyberspace into spatial settings that not only afford social interaction, but, like physical places, also embody and express cultural values. At the same time, because Cyberspace lacks materiality, is free from physical constraints, and because it can only be ‘inhabited’ by proxy, these ‘places’ may not necessarily resemble their physical counterparts.

title Past, Present, and Future of User Interface Software Tools
source Carroll, J. (eds), Human-Computer Interaction in the New Millennium, Addison Wesley, ACM Press, New York, pp. 213–233
summary A user interface software tool helps developers design and implement the user interface. Research on past tools has had enormous impact on today's developers-virtually all applications today were built using some form of user interface tool. In this paper, we consider cases of both success and failure in past user interface tools. From these cases we extract a set of themes which can serve as lessons for future work. Using these themes, past tools can be characterized by what aspects of the user interface they addressed, their threshold and ceiling, what path of least resistance they offer, how predictable they are to use, and whether they addressed a target that became irrelevant. We believe the lessons of these past themes are particularly important now, because increasingly rapid technological changes are likely to significantly change user interfaces. We are at the dawn of an era where user interfaces are about to break out of the "desktop" box where they have been stuck for the past 15 years. The next millenium will open with an increasing diversity of user interfaces on an increasing diversity of computerized devices. These devices include hand-held personal digital assistants (PDAs), cell phones, pagers, computerized pens, computerized notepads, and various kinds of desk, and wall-size computers, as well as devices in everyday objects (such as mounted on refrigerators, or even embedded in truck tires). The increased connectivity of computers, initially evidenced by the World-Wide Web, but spreading also with technologies such as personal-area networks, will also have a profound effect on the user interface to computers. Another important force will be recognitionbased user interfaces, especially speech, and camera-based vision systems. Other changes we see are an increasing need for 3D and end-user customization, programming, and scripting. All of these changes will require significant support from the underlying user interface software tools.

title Realism vs. Reality in Digital Reconstruction of Cities
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

title The End of Methodology - Towards New Integration

summary The present paper is devoted to the deliberation on the genesis and development of designing from the point of view of the potential use of computers in the process. Moreover, it also presents the great hopes which were connected with the use of the systematic designing methods in the 1960’s, as well as the great disappointment resulting from the lack of concrete results. At this time a great deal of attention was paid to the process of design as a branch of a wider process of problem-solving. Many people believed that the intuitive methods of design traditionally used by architects were incapable of dealing with the complexity of the problems to be solved. Therefore, the basic problem was the definition of a vertical structure of the designing process, which would make it possible to optimise each process of architectural design. The studies of design methodology directed at the codification of the norms of actions have not brought about any solutions which could be commonly accepted, as the efforts to present the designing process as a formally logical one and one that is not internally “uncontrary” from the mathematical point of view, were doomed to fail. Moreover, the difficulties connected with the use of the computer in designing were caused by the lack of a graphic interface, which is so very characteristic of an architect’s workshop. In result, the methodology ceased to be the main area of the architect’s interest and efforts were focused on facilitating the method of the designer’s communication with the computer. New tools were created, which enabled both the automatic generation of diversity and the creation of forms on the basis of genetic algorithms, as well as the presentation of the obtained results in the form of rendering, animation and VRML. This was the end of the general methodology of designing and the beginning of a number of methods solving the partial problems of computer-supported design. The present situation can be described with the words of Ian Stewart as a “chaotic run in all directions”. An immediate need for new integration is felt. Cyber-real space could be a solution to the problem. C-R-S is not a virtual reality understood as an unreal world. Whilst VR could be indeed treated as a sort of an illusion, C-R-S is a much more realistic being, defining the area in which the creative activities are taking place. The architect gains the possibility of having a direct contact with the form he or she is creating. Direct design enables one to creatively use the computer technology in the designing process. The intelligent system of recognising speech, integrated with the system of virtual reality, will allow to create an environment for the designer – computer communication which will be most natural to the person. The elimination of this obstacle will facilitate the integration of the new methods into one designing environment. The theoretical assumptions of such an environment are described in the present paper.

summary Two features of this dynamic workflow system make it suitable for the use of quasi-intelligent agents: (a) workflow processes need not be fully specified, and so can be non-prescriptive in approach, and (b) a job can be modified independently of the process of which it is an instance, and so some participants may have permissions to change its course. In the architecture that has been chosen for the research, web clients are used, and web agents generate suggestions based on analysis of the process itself, the current job, and the records of previous jobs.

title Using Computer Game to Develop Advanced AI
source Computer, 34 (7), July pp. 70-75
summary Although computer and video games have existed for fewer than 40 years, they are already serious business. Entertainment software, the entertainment industry's fastest growing segment, currently generates sales surpassing the film industry's gross revenues. Computer games have significantly affected personal computer sales, providing the initial application for CD-ROMs, driving advancements in graphics technology, and motivating the purchase of ever faster machines. Next-generation computer game consoles are extending this trend, with Sony and Toshiba spending $2 billion to develop the Playstation 2 and Microsoft planning to spend more than $500 million just to market its Xbox console [1]. These investments have paid off. In the past five years, the quality and complexity of computer games have advanced significantly. Computer graphics have shown the most noticeable improvement, with the number of polygons rendered in a scene increasing almost exponentially each year, significantly enhancing the games' realism. For example, the original Playstation, released in 1995, renders 300,000 polygons per second, while Sega's Dreamcast, released in 1999, renders 3 million polygons per second. The Playstation 2 sets the current standard, rendering 66 million polygons per second, while projections indicate the Xbox will render more than lOO million polygons per second. Thus, the images on today's $300 game consoles rival or surpass those available on the previous decade's $50,000 computers. The impact of these improvements is evident in the complexity and realism of the environments underlying today's games, from detailed indoor rooms and corridors to vast outdoor landscapes. These games populate the environments with both human and computer controlled characters, making them a rich laboratory for artificial intelligence research into developing intelligent and social autonomous agents. Indeed, computer games offer a fitting subject for serious academic study, undergraduate education, and graduate student and faculty research. Creating and efficiently rendering these environments touches on every topic in a computer science curriculum. The "Teaching Game Design " sidebar describes the benefits and challenges of developing computer game design courses, an increasingly popular field of study

source Automation in Construction 10 (5) (2001) pp. 631-637
summary Concurrent engineering draws together team working and cooperation, with the aim of reducing the need for costly design modifications in the later stages of design and product development. However, the complexities arising in the process of design, in general, defy formal analysis and computational support is required. In providing intelligent computational support for concurrent engineering, a combination of various problem-solving strategies may be required for complex design situations. It is proposed that an appropriate model for such provision is in the form of a set of interacting autonomous intelligent agents, possessing different problem-solving capabilities and differing degrees of intelligence. The requirements for such agent-based design support are discussed and possibilities for its realisation, with the aid of Web technology, in a distributed design environment are explored.

title Quill A Gesture Design Tool for Pen-based User Interfaces
source U.C. Berkeley
summary This dissertation describes the motivation, design, and development of a tool for designing gestures for pen-based user interfaces. Pens and other styli have been ubiquitous for recording information for centuries. Recently, pen-based computers have recently become common, especially small devices such as the Palm Pilot. One benefit pens provide in computer interfaces is the ability to draw gestures—marks that invoke commands. Gestures can be intuitive and faster than other methods of invoking commands. However, our research shows that gestures are sometimes misrecognized and hard to remember. We believe these problems are due in part to the difficulty of designing “good” gestures—that is, gestures that are easy to remember and are recognized well—and the lack of tools for helping designers create good gestures. We believe that an improved gesture design tool can help interface designers create good gestures for their applications. Since people confuse similar objects and misremember them, we performed experiments to measure why people perceived gestures as similar. We derived computational metrics for predicting human perception of gesture similarity. Based on the results of our experiments, we developed a gesture design tool, quill. The tool warns designers about gestures that may be hard to remember or recognize, and provides advice about how to improve the gestures. It also provides a convenient way to test recognition of gestures. To evaluate quill, a user study was performed with 10 professional user interface designers and one professional web designer. All designers were able to create gesture sets using quill, but not all designers benefited from quill’s suggestions. More work is needed to make suggestions useful for most designers. The primary contributions of this work are: • Improved understanding of the gesture design process, including the types of problems people encounter when designing gestures. • Computational models for predicting human-perceived gesture similarity. • Confirmation of the importance of good naming for gesture memorability. • An intelligent gesture design tool, quill, which automatically warns designers about potential problems with their gestures and advises them about how to fix these problems. This work also suggests several areas for future work in the areas of gesture design tools and gesture similarity and memorability.

summary It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.
