title	Using Virtual Reality Aided Design Techniques for Three-dimensional Architectural Sketching
doi	https://doi.org/10.52842/conf.acadia.1996.199
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 199-212
summary	With this paper we would like to introduce a system which supports the early phases of the architectural design process. The system consists of two main components: the software solution "voxDesign" and the physical environment "platform". Our aims are: to formulate, develop, and evaluate an architectural design system through the use of VR (virtual reality) space. The exploration and development of design intentions is supplemented by a new method of three dimensional sketching. In the second part of this paper we will show how these components were used to train students in architecture and design at our university. Parts of this paper were published to the academic public at "Designing Digital Space". (Regenbrecht 1996)

title	A Case for Computer-Assisted Creativity through Clarity, Project 12 CAD and Beyond
source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 31-35
summary	A paper exploring the opportunities of different Design Media for the benefit of Architectural and Urban Composition. It is argued that during the design process, the designer develops Models for a projected end result, which are visualised in the form of Images using traditional media. The Computer affords the possibility of creating (virtual) Models from which Images can be taken. Current types of Computer Interfaces still form an obstacle for creative computer assisted design, comparable to Sketching. It is argued that the Clarity of the medium will need to be enhanced, if it is to become an Instrument for truly creative design. Using the example of an educational, practical CAD exercise, the case for' Clarity for the benefit of creative Computing is put forward.

title	ADELINE, an Integrated Approach to Lighting Simulation
source	Proceedings of Right Light 4, 4th European Conference on Energy-Efficient Lighting, pp.99-103
summary	The use of daylighting and artificial lighting simulation programs to calculate complex systems and models in the design practice often is impeded by the fact that the operation of these programs, especially the model input, is extremely complicated and time-consuming. Programs that are easier to use generally do not show the calculation capabilities required in practice. A second obstacle arises as the lighting calculations often do not allow any statements regarding the interactions with the energetic and thermal building performance. Both problems are mainly due to a lacking integration of the design tools of other building design practitioners as well as due to insufficient user interfaces. The program package ADELINE (Advanced Daylight and Electric Lighting Integrated New Environment) being available since May 1996 as completely revised version 2.0 presents a promising approach to solve these problems. This contribution describes the approaches and methods used within the international project IEA Task 21 for a further development of the ADELINE system. Aim of this work is a further improvement of user interfaces based on the inclusion of new dialogs and on a portation of the program system from MS-DOS to the Windows NT platform. Additional focus is laid on the use of recent developments in the field of information technology and experiences gained in other projects on integrated building design systems, like for example EU-COMBINE, in a pragmatical way. An integrated building design system with open standardized interfaces is to be achieved inter alia by using ISOSTEP formats, database technologies and a consequent, object-oriented design.

title	Ambiguous Intentions: a Paper-like Interface for Creative Design
source	Proceedings UIST ’96 Seattle Washington, pp. 183-192
summary	Interfaces for conceptual and creative design should recognize and interpret drawings. They should also capture users' intended ambiguity, vagueness, and imprecision and convey these qualities visually and through interactive behavior. Freehand drawing can provide this information and it is a natural input mode for design. We describe a pen-based interface that acquires information about ambiguity and precision from freehand input, represents it internally, and echoes it to users visually and through constraint based edit behavior.

title	A study of 2D- and 3D-oriented architectural drawing production methods
source	Automation in Construction 5 (4) (1996) pp. 273-283
summary	The purpose of this paper is to present drawing production methods based on the difference between 2D- and 3D-oriented approaches. This study emphasizes the comparison of the two approaches in data production, updating and analysis. Architectural CAD drawings are outputted from design information through a computational interface. A drawing production model (P) can be represented by a database (DB) and an interface (I). The input interface is the input or update method between users and application systems. The output interface is the method of presenting architecture drawings like plans, elevations, sections and details based on input data. Under the constraints of a predefined data structure, the computational interface determines the efficiency and characteristics of input and output data. Drawing production methods can be classified into three types: segregating drawing files, applying reference files and constructing a virtual building model. These types come with different interfaces: 2D drafting has the same input and output interface, whereas constructing a 3D model is achieved using a different interface. A digital building model is defined as the electronic information of a whole building which is assembled by components with attributes. 2D- and 3D-oriented drawing methods are compared, based on items such as the required preparation before drafting, consistency of plans, elevations and sections, ease of modification, drafting efficiency, number of persons involved, and analysis potential.

title	HoloSketch: A Virtual Reality Sketching/Animation Tool Special Issue on Virtual Reality Software and Technology
source	Transactions on Computer-Human Interaction 1995 v.2 n.3 pp. 220-238
summary	This article describes HoloSketch, a virtual reality-based 3D geometry creation and manipulation tool. HoloSketch is aimed at providing nonprogrammers with an easy-to-use 3D "What-You-See-Is-What-You-Get" environment. Using head-tracked stereo shutter glasses and a desktop CRT display configuration, virtual objects can be created with a 3D wand manipulator directly in front of the user, at very high accuracy and much more rapidly than with traditional 3D drawing systems. HoloSketch also supports simple animation and audio control for virtual objects. This article describes the functions of the HoloSketch system, as well as our experience so far with more-general issues of head-tracked stereo 3D user interface design.

title	The Right Tool at the Right Time - Drawing as an Interface to Knowledge Based Design Aids
doi	https://doi.org/10.52842/conf.acadia.1996.191
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 191-199
summary	Designers use different symbols and diagrams in their drawings to explore alternatives and to communicate with each other. Therefore, a useful design environment should attempt to infer the designer's intentions from the drawing and, based on this inference, suggest appropriate computational tools for the task at hand. For example, a layout bubble diagram might activate design cases with similar configurations. Scribbles of view lines on a floor plan might bring up a spatial analysis tool. This research aims to develop an integrated digital sketching environment to support early design activities. The paper proposes RT, an intelligent sketch environment that provides the designers with the right tools at the right time.

title	The Electronic Cocktail Napkin – a computational environment for working with design diagrams
source	Design Studies, 17 (1), pp. 53-69
summary	The Electronic Cocktail Napkin is an experimental computer-based environment for sketching and diagramming in conceptual design. The project's goal is to develop a computational drawing environment to support conceptual designing in a way that leads smoothly from diagrams to more formal and structured representations of schematic design. With computational representations for conceptual designs, computer-supported editing, critiquing, analysis, and simulation can be employed earlier in the design process, where it can have a greater impact on outcomes. The paper describes the Electronic Cocktail Napkin program - its recognition and parsing of diagrams and management of spatial constraints, its drawing environment, and two experimental query-by-diagram schemes for retrieving information from architectural databases.

title	The integral role of conventional sketching in conceptualisation
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Architectural Design Studies is an expanding research area, which recently has experienced dramatic shifts in approach. The successful application of computing to architectural practice has created pressure leading to a rediscovery of Architectural Drawing. The thrust of recent design studies is toward the early stages of the design process, where the modes of conception, human perceptual, and cognitive systems are the focus. In this paper we endeavour to examine the integral role of sketching in conceptualisation. A modelling technique relating to both the design and the graphic process 'sheds light' on the interaction between thought and drawing. Data from a protocol analysis is tested within the framework of the proposed model.

source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 387-390
summary	At many schools of architecture the studies are directed to practical, professional use, and this fact results in different attitudes. But normally, it will be so that the longer the student goes in the study the more aspects from practice will be involved. Therefore, the studies passes from the work with the design itself and the more artistic sides to the work with planning and production. The basis of the educational progress and the professional level is research and development. Within CAD it is important that this research develops as well the theoretical foundation and includes experience in the practical use. An attitude which prioritizes the practical qualifications late in the studies has of course an effect in the CAD instruction. Tendencies to consider the computer to be a tool of drawing and visualization will dominate, and the work with structuralized information models for a general documentation has had minor interest until now, and this also includes the use of professional applications developed from different conventions in support of collaboration and quality control. The dialogue between the environment of education and research on one hand and the professional business in practice must be considered important for the developing process in the use of CAD and for the building of usable IT models. The work with "The Masonry House" and later "The Building Trade House" tries to expose how a deliberate structuralization of the CAD model early in the sketching- and planning process can support as well the more esthetic estimates as the building technology documentation. And also point out the professional qualifications bound up with 11 to be integrated in the study course.

title	The Design and Evaluation of Transparent User Interfaces. From Theory to Practice
source	University of Toronto, Toronto
summary	The central research issue addressed by this dissertation is how we can design systems where information on user interface tools is overlaid on the work product being developed with these tools. The interface tools typically appear in the display foreground while the data or work space being manipulated typically appear in the perceptual background. This represents a trade-off in focused foreground attention versus focused background attention. By better supporting human attention we hope to improve the fluency of work, where fluency is reflected in a more seamless integration between task goals, user interface tool manipulations to achieve these goals, and feedback from the data or work space being manipulated. This research specifically focuses on the design and evaluation of transparent user interface 'layers' applied to graphical user interfaces. By allowing users to see through windows, menus, and tool palettes appearing in the perceptual foreground, an improved awareness of the underlying workspace and preservation of context are possible. However, transparent overlapping objects introduce visual interference which may degrade task performance, through reduced legibility. This dissertation explores a new interface technique (i.e., transparent layering) and, more importantly, undertakes a deeper investigation into the underlying issues that have implications for the design and use of this new technique. We have conducted a series of experiments, progressively more representative of the complex stimuli from real task domains. This enables us to systematically evaluate a variety of transparent user interfaces, while remaining confident of the applicability of the results to actual task contexts. We also describe prototypes and a case study evaluation of a working system using transparency based on our design parameters and experimental findings. Our findings indicate that similarity in both image color and in image content affect the levels of visual interference. Solid imagery in either the user interface tools (e.g., icons) or in the work space content (e.g., video, rendered models) are highly interference resistant and work well up to 75% transparent (i.e., 25% of foreground image and 75% of background content). Text and wire frame images (or line drawings) perform equally poorly but are highly usable up to 50% transparent, with no apparent performance penalty. Introducing contrasting outlining techniques improves the usability of transparent text menu interfaces up to 90% transparency. These results suggest that transparency is a usable and promising interface alternative. We suggest several methods of overcoming today's technical challenges in order to integrate transparency into existing applications.

title	Integrated Energy Modeling for Computational Building Design Assistance
source	Carnegie Mellon University, Department of Architecture
summary	Insights into the importance of energy modeling in building design have not yet resulted in the sufficient and systematic use of modeling tools in practice. In recent years, there has been considerable discussion on the limitations of simulation tools, and there is a noteworthy consensus as to the nature of the contributing factors (material and time implications, problematic user-interfaces, inefficient data communication structures, poor integration with CAD systems, absence of 'active' design support). This thesis deals with three research questions that are especially pertinent to the quest for active, multi-aspect design and simulation environments: (1) The appropriateness and feasibility of a methodologically consistent performance modeling approach through the entire design process. (2) Strategies for a structurally 'seamless' containment of performance simulation within a computational design environment. (3) Technologies to facilitate dynamic and interactive performance-to-design mapping. At a paradigmatic level, this thesis critically examines the existing responses to each of these questions, and proposes alternative computational frameworks and technologies to overcome some of the system-immanent ('endogenous') limitations of the existing approaches. At an operational level, this thesis demonstrates the proposed solutions by implementing an active thermal simulation module (NOD

source	Research report TR96-029, Department of Computer Science, University of North Carolina, Chapel Hill
summary	This paper presents a description of the interaction techniques used in the Chapel Hill Immersive Modeling Program (CHIMP). CHIMP is intended for the preliminary stages of architectural design. It is an immersive system; users work directly within a virtual world. The main goal has been to develop interaction techniques that exploit the benefits of working immersed while compensating for its limitations. Interaction techniques described and discussed in this paper include: . Action at a distance . Look-at menus . Remote controls (hand-held widgets) . Constrained object manipulation using twohands . Two-handed control panel interaction . Worlds in miniature .

title	Designing Visual Interfaces: How to Create Communication -- Oriented Solutions Tutorial 3
source	Proceedings of ACM CHI 96 Conference on Human Factors in Computing Systems 1996 v.2 pp. 332-333
summary	This tutorial describes a number of fundamental techniques applied routinely in communication-oriented visual design. The orientation, process, training, and culture of the visual design disciplines (graphic design, industrial design, interior design, architecture) are essential components of effective interface design. Unfortunately, few software developers or human factors engineers receive any training in these disciplines. This tutorial describes important design rules and techniques internalized by every visual designer through coursework and studio experience. While mastery will indeed require extended practice, the techniques we describe are not difficult to understand and can be immediately applied to real-world problems. We draw our background, training, and influence from the rational, functional, information-oriented perspective of the Modernist design ethic. Because all graphical user interfaces are communication systems, we believe their design should reflect these same values. Our tutorial is organized not along the traditional subdisciplines of color, typography, or ideation, but along the problems of graphical interface design as experienced in commercial software development. We describe basic design principles (the what and why), common errors, and practical techniques (the how) for each of the six major areas outlined below.

title	A computer simulation model of the TU district of Delft with use of the GIS and VR
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	One of the big problems for GIS users is a luck of such an visual presentation of data which will easily transform them into a spatial image. Existing systems based on Human-Computer-Interfaces (Ha) have limitations and for this reason it is necessary to discover new explicit way of spatial data presentation and manipulation. Virtual Reality technology with its specificity and characteristics based on spatial displaying and multisensory interactivity, give to VR users a new promising possibility to solve GIS limitations. This research is an exploration of integration of GIS and yR. VR is a kind of production of a simulation of a real world, and GIS-databases contain data that describe this world, therefore a success of combination of both technologies is very probable. This research shows possibilities for creating a virtual GIS world in which is possible to handle, explore, analyse and present spatial data by free navigation through a virtual model. The virtual model of Delft University of Technology's Campus presents Virtual Reality as a new type of 3D interface for GIS and demonstrates some basic GIS functions in virtual environment. It has been created by importing of GIS databases into VR system. Virtual model is based on geometric and attributive data. GIS functionality is enabled by 3D interface objects, that symbolically and semantically represents GIS functions. Their use should initiate intuitive users action. This application combines spatial data, user interface, text, sound, thematic data and virtual hypertext. Virtual model enables the use of quantitative and qualitative information. The results of the research can be implemented to support design strategies ax! decision making in the field of physical and urban planning.

title	Case-based conceptual design information server for concurrent engineering
source	Computer-Aided Design, Vol. 28 (5) (1996) pp. 361-369
summary	Conceptual design requires processing information from diverse sources in order to define the functional requirements, operating constraints, and evaluation criteria pertinent to accomplishing a prescribed goal.Historically, the design process focused on the functionality of an artifact for the end customer. Concurrent engineering broadens this focus to account for the concerns of `customers' not previously considered --those along the entire life cycle of an artifact, i.e. marketing, design, manufacture, distribution, operation and disposal. Expanding the design focus to include all of these customers places far greater informationaldemands on the designer. Case-based reasoning applies experience stored in a computerized form to solving similar problems in slightly altered contexts. It has been applied successfully to routine design whereboth the form and the content of design information can be encoded symbolically and manipulated using artificial intelligence techniques. Concurrent conceptual design presents unique problems for such anapproach because design information must be considered at many levels of abstraction and from many viewpoints.We describe an approach that provides the designer with case-based conceptual design information stored in the richly expressive medium of hypermedia (hypertext incorporating multimedia). Design cases ofindustry `best practices' in concurrent engineering are indexed to provide access through multiple interfaces, allowing the user to browse, explore, or pinpoint design case information. The Conceptual DesignInformation Server (CDIS) is implemented using emerging internet standards, such as those associated with the World Wide Web (WWW) and Wide Area Information Service (WAIS), coupled to a robustStructured Query Language (SQL) database and traditional cad packages.

summary	There are many of us trying to make place for CAAD in a natural way in the Curriculum of the Architect school. We would like to make CAAD useful to the students already during their studies. Even if we have the support of our collegues for running courses there is very often no space in the timetable. And even if we have all the entusiasm of our students it is hard to practice your CAAD knowledge on projects where it is not asked for. The education of architects in the use of computers has lead me to try to find "the roots of education of architects" in general. A collegue of mine in a bookshelf of course litterature in Informatics found and put into my hands "Educating the reflective practitioner" by Donald Schön. It lead to an interesting process of personal reflection and discussion within our CAAD team. We think by the way that the theme of the conference points to the heart of the message in Donald Schöns book and we are inviting him as a key note speaker at the Conference.
