title	A VR User Interface for Design by Features
source	Timmermans (ed.) Proceedings of the 4th Conference on Design and Decision Support Systems in Architecture and Urban Planning, Maastricht
summary	We present the design of a Virtual Reality based user interface (VR-UI). It is the interface for the VR-DIS system, a design application for the Building and Construction industry (VRDIS stands for Virtual Reality - Design Information System). The interface is characterised by a mixed representation of the task domain: an analogue "mock-up view" is being integrated with a descriptive "feature view". It uses a Fish Tank VR configuration which integrates the virtual objects in the designer's normal working environment. The issues underlying the design of the feature view are discussed, as well as the choice of input devices.

title	Wireless communication and computing at the construction jobsite
source	Automation in Construction 7 (4) (1998) pp. 327-347
summary	For many years, the walkie-talkie has been synonymous with the construction industry. During jobsite project execution, there are three variables which can either hinder or facilitate successful results, namely, quality, quantity, and timing of information. Wireless data communications technology is capable of delivering just-in-time information within the `last mile' between the trailer and a desired location on the jobsite. This paper reports on a study which surveyed information needs at the jobsite, emerging wireless data communications technology, and assessed the extent to which wireless data technology can fulfill the information needs of the jobsite [J.M. de la Garza, I. Howitt, Wireless communication and computing at the jobsite, Research Report 136-11, Construction Industry Institute, Austin, TX, 1997]. We have organized jobsite information needs into the following ten categories: (a) requests for information, (b) materials management, (c) equipment management, (d) cost management, (e) schedule and means and methods, (f) jobsite record keeping, (g) submittals, (h) safety, (i) QC/QA, and (k) future trends. Each category was analyzed in terms of its appropriateness to take advantage of wireless technology. The four formats considered to transmit information wirelessly were: (a) live voice, (b) live video, (c) batched data, and (d) live data. Current wireless communication technology has been classified into the following five classes: (a) circuit-switched wireless data systems, (b) packet-switched wireless data systems––this class was further subdivided into specialized mobile radio systems and cellular digital packet data systems, (c) wireless local area networks, (d) paging systems, and (e) satellite-based data communications. A primer for wireless communications covering both fundamental and advanced communications concepts has also been included to enable a better understanding of the issues involved in making trade-offs while configuring a wireless jobsite communication system. The example presented in this paper shows how a contractor can define a subset of information needs by choosing from those already articulated herein and determine if a given wireless technology should even be considered as a viable way of meeting the information needs that such company has.

title	Collaboration and coordination in architectural design: approaches to computer mediated team work
source	Automation in Construction 7 (6) (1998) pp. 465-473
summary	The paper reports on three projects at our laboratory that deal respectively with synchronous collaborative design, asynchronous collaborative design, and design coordination. The Electronic Cocktail Napkin and its mobile extension that runs on hand-held computers supports synchronous design with shared freehand drawing environments. The PHIDIAS hypermedia system supports long-term, asynchronous collaboration by enabling designers of large complex artifacts to store and retrieve rationale about design decisions and the Construction Kit Builder (CKB) supports team design by supporting a priori agreements among team members to avoid conflicts.

title	Replacement and Transformation as a Key to Schematic Design Thinking - 3-D Modeling System which Supports Design Thinking
doi	https://doi.org/10.52842/conf.caadria.1998.365
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. 365-374
summary	This paper analyses a prototype of a 3D modeling system that can support schematic design development and begins with very abstract representation elaborates it step by step into a detailed representation. Using Mitchell's concept of a TOPDOWN system for 2D sketches as the basis, the authors proposed a design process model and a prototype that allows both bottom up additive processes in exploring the design frame and top down processes for the design refinement of each building element. Various utilities of replacing and transforming graphic objects as well as those that can control shapes and the location of those objects with construction lines have been proposed. The authors discussed possible use of the system and topics for future study by reviewing case studies.

title	Assessment technologies for sewer system rehabilitation
source	Automation in Construction 7 (4) (1998) pp. 259-270
summary	Due to their low visibility, rehabilitation of underground utilities is neglected until a catastrophic failure occurs. This results in costly and difficult rehabilitation options. A key issue governing the selection of appropriate rehabilitation technologies, is the availability of adequate information concerning the condition of infrastructure. This paper presents an overview of the current methods and new developments for sewer line condition assessment. The focus of the paper is on internal inspection technologies, which investigate infiltration/inflow problems, and assess the structural conditions of sewer pipes. The primary internal inspection method is closed-circuit television (CCTV) inspection. The quality of information obtained using traditional CCTV is dependent on the experience and skill of the technician and the reliability of the TV picture. Other non-destructive, remote-sensing diagnostic methods include: infrared thermography system, sonic distance measurement method and ground penetrating radar technique. The features of three new promising multi-sensory systems, namely, KARO, PIRAT and SSET, are explained. The paper also discusses ongoing research efforts for automated interpretation of multi-sensory data.

title	A Virtual Reality User Interface for a Design Information System, CCAI: the Journal for the Integrated Study of Artificial Intelligence
source	Cognitive Science and Applied Epistemology, Rijks Universiteit Gent
summary	The computer is a tool, a complex artefact that is used to extend our reach. A computer system can provide several kinds of services, but against these services stands a supplementary task that the user must deal with: the communication with the computer system. We argued that Virtual Reality (VR) can fundamentally improve the user interface by rendering on the common experiential skills of all users. We present the theoretical basis for this, referring to Donald Norman's theory. We show that VR provides at least theoretically, the means to take a big step in the direction of an ideal user interface. As an example of a innovative application of VR in user interface design, we presented the VR-DIS system; an interdisciplinary design system for the building and construction industry. We discuss the issues underlying the design of its VR interface.

title	Prototyping of Designs in Virtual Reality
source	H.J.P. Timmermans (ed.), 3rd Design and Decision Support Systems in Architecture and Urban Planning Conference, Vol I: Architecture Proceedings, pp. 13-25
summary	Conventional CAD systems have not yet proven their ability to provide support for activities which characterise the early conceptual phase of design. We propose to refer to this set of capabilities of the human designer in conventional design as, design prototyping. We define the theoretical limitations of current CAD systems for supporting design prototyping, and postulate the potential of functionally dedicated, task related, CAD modules in Virtual Reality as a means to provide a unique form of a knowledgebased, visual design support environment for design prototyping support. We are currently engaged in a research program in which we explore CAD as a medium to support early conceptual design through rapid prototyping of architectural form. Furthermore we are exploring Virtual Reality as a potential design prototyping environment in which prototypes of designs can be constructed, communicated and visually evaluated at a high level of verisimilitude. In the first phase we have built the prototype system VIDE. This system has been used for extensive internal evaluation. In the ongoing second phase we are constructing an empirical research to observe designers at work on design prototyping in the Virtual Reality environment.

title	Towards a Taxonomy of Virtual Reality User Interfaces
source	Proceedings of the International Conference on Information Visualisation (IV97), pp. 17-29
summary	Virtual reality based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application oriented knowledge is available. As a basis for such a future VRUI design theory, a taxonomy of VRUIs is required. A general model of human computer communication is formulated. This model constitutes a frame for the integration of partial taxonomies of human computer interaction that are found in the literature. The whole model constitutes a general user interface taxonomy. The field of VRUIs is described and delimited with respect to this taxonomy.

title	Abstract but Tangible, Complex but Manageable
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the VR-DIS research program, an innovative design-information modelling technique has been proposed that is based on features. In this modelling technique, the designer is invited not only to model the form and spatial aspects of his or her design, but also to model the structure of the data behind the design. The designer is offered a way to control how abstract design data is structured and stored. In this way, the designer is given the power to model concepts like conformity, contrast, and scale on the formal data level, and this for both graphical and non-graphical design characteristics. Further, the designer is invited to input formal descriptions of own design concepts, and use these personal concepts during the design process. With this new information modelling technique, we expect that the designers will be better capable to handle the complexity of linking diverse kinds of information involved in a design process. This new way of computer aided design offers a unique design freedom: any design concept becomes addressable. On the other hand, this technique also puts the responsibility for the content of the CAD database entirely in the hands of the designer. In order to be able to enjoy the design freedom fully and at the same time handle the responsibility over the design database, a computer tool is needed that shows the precise content of the database, and that is easy and quick to interact with. Only with such a tool, the designer will be capable of keeping the complex data model in pace with his or her design reasoning. To realise this requirement, a “feature browser” has been developed with a 3D graphical user interface. It shows the data objects as 3D blocks, mutually linked by rubber-band arrows that closely reflect the database structure. The whole forms an interactive 3D graph. The intuitiveness and user friendliness of the interface was improved by adding features like the visualisation of the browsing history, the visualisation of link-semantics, and animated visual feedback effects. The hardware part of the interface is worked out as a Fish Tank VR set-up. This hardware configuration improves the experienced realism of the displayed 3D objects up to a feeling of physical presence. The interface as a whole therefore provides a highly attractive display of the abstract design data; abstract but tangible. It is a tool in which complex data structures can be explored and controlled: complex but manageable.

title	Genetic Space
source	A.D.: Architects in Cyberspace II, vol.68, no.11-12, pp.68-73
summary	The twentieth century is the century of convergence. No other century has witnessed the development and profusion of new ideas as the twentieth century, and no other century has experienced the range and scope of events that transpired globally to the extent as this century. Various historical formations and discoveries, unleashed by the Enlightenment, have profoundly changed and transformed the course of human civilization and lead to the maturation of the idea of modernity in this century. With two years left to the start of the next millennium, we are experiencing the effects of modernity that have channeled powerful innovations into the dawn of a new era that could lead, potentially, beyond modernity. More than anything, it signals one of the major premises of the enlightenment to radicalize the substance of nature through the substance of reason and, thereby, altering the modality of the cultural universe of humanity into a genuine cosmopolitical concept. The synthesis of energy, matter and information into a three-parameter system of explanation has created conditions that allow us to think the unthinkable and extend our imagination to the limits of the conceivable. Modernity, from a metaphysical standpoint, brings to light the concept of a transcendental reason that aims to clarify the conditions of possibility for reason as an apriori given. As a consequence, it paved the way for a systemic constitution of a cosmic concept of reason that partakes in the arrival of alien intelligence and one that seems destined to project itself into an ontological domain of its own making. If modernity is an unfinished project, as claimed by some, its program is, nonetheless, being transformed into a cosmogenetic principle where synthesis is the pre-eminent outcome of a return to a second nature, i.e., a transcendent concept of nature. Even though the transcendental dialectic of critical reason is directed towards the timeless unity of the unconditioned, the genitive logic implicit within cosmic reason, itself a form of recursive self-propelling intelligence, appears to be animated by a projective force capable of engendering and pro-creating in the evolutionary sense of the term.

summary	A l'heure où l'ordinateur n'est pas seulement utilisé comme instrument de dessin mais de plus en plus mis à contribution comme outil d'aide à la conception, l'approche de l'informatique en Ecole d'Architecture demande une pédagogie adaptée aux disciplines enseignées qui va au delà de l'apprentissage de l'utilisation du matériel et des logiciels. Le travail demandé en 4ème année aux étudiants de l'école d'architecture de Marseille Luminy repose sur l'analyse d'un projet architectural pris dans l'oeuvre d'un architecte de leur choix. Cette analyse doit amener les étudiants à proposer une méthode de travail basée sur les outils informatiques mis à leur disposition qui les aide par la saisie et la représentation informatique du projet, à formuler et évaluer les hypothèses de conception qui ont menées à la réalisation du projet étudié. Cette approche basée sur l'analyse du projet ouvre la perspective de l'utilisation de l'outil informatique dans les étapes de l'analyse, de la conception et de la communication d'un projet.

title	Data Visualization Methods for the Blind using Force Feedback and Sonification
source	Stein, M. (Ed.). Telemanipulator and Telepresence Technologies V. Vol. 3524
summary	Research in the field of scientific visualization has begun to articulate systematic methods for mapping data to a perceivable form. Most work in this area has focused on the visual sense. For blind people in particular, systematic visualization methods which utilize other sense need further development. In this work we develop methods for adding aural feedback to an existing haptic force feedback interface to create a multimodal visualization system. We examine some fundamental components of a visualization system which include the following: characterization of the data, definition of user directives and interpretation aims, cataloging of sensual representations of information, and finally, matching the data and user interpretation aims with the appropriate sensual representations. We focus on the last two components as they relate to the aural and haptic sensor. Cataloging of sensual representations is drawn form current research in sonification and haptics. The matching procedure can be thought of as a type of encoding which should be the inverse of the decoding mechanism of our aural and haptic systems. Topics in human perception are discussed, and issues related to the interaction between the two sensor are addressed. We have implemented a visualization system in the from of a Windows NT application using a sound card and a 3 DOF point interaction haptic interface. The system present a 2D data set primarily as a polygonal haptic surface although other capabilities of the haptic sensor are utilized such as texture discernment. In addition, real time aural feedback is presented as the user explores the surface. Parameters of sound such as pitch and spectral content are used to convey information. Evaluation of the system's effectiveness as an assistive technology for the blind reveals that combining aural and haptic feedback improves visualization over using either of the two senses alone.

title	Network-Based Dynamic Evaluation Process for Urban Landscapes
doi	https://doi.org/10.52842/conf.caadria.1998.213

summary	When designing large-scale projects that affect urban landscapes such as the construction of power stations, it is important for a designer, to be able to predict how the landscape will be changed and public opinion in regard to the design stage. In order to support the communication between the public and the designer in the design process, authors have proposed a Network-Based Dynamic Evaluation Process (NDEP) for urban landscapes with WEB. This process can achieve a consensus decision, by applying the interactive cycles of proposal and evaluation to the design process. In this paper the authors outlined the framework of the process, the evaluation method by AHP, and a case study of an experimental production system.
