title What can real-time positioning do for construction?
source Automation in Construction 5 (2) (1996) pp. 79-89
summary New technologies are now available that can rapidly measure three-dimensional coordinates of objects. The integration of these fast 3-D Real-time Position Measurement (D-RtPM) devices and CAD (3D-RtPM/CAD) technologies can be viewed as a better tool for surveyors or as a means to change the most fundamental concepts of the construction industry. 3D-RtPM/CAD is a better surveying tool; however, 3D-RtPM/CAD as the basis for fundamental change within the construction industry is the issue. There are several potential technologies that can provide real-time position measurement. This paper will limit presentation to two of these. The first is based on recent developments in Global Positioning Systems. The second is a new laser-based product, OdysseyTM (Odyssey is a trademark of Spatial Positioning Systems, Inc.). Odyssey received the NOVA award in March, 1995 because of its recognized performance enhancement to the construction industry. These positioning systems provide the capability for equipment and crafts people to view the project from a graphical representation in which they see their position interactively updated. Potential benefits to the construction industry are presented. The research needed achieving maximum benefits of these systems is also presented.

doi https://doi.org/10.52842/conf.acadia.1995.209
source Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 209-227
summary In spite of the rapid increase in functionality and resources provided by CAD systems, productivity growth expected from their use has been difficult to achieve. Although many surveys describe this "productivity puzzle", few studies have been conducted on actual CAD users to understand its causes. In an effort to understand this issue, the first author visited a federal architectural office and observed CAD users in their natural setting using ethnographic techniques developed by cultural anthropologists. This paper describes preliminary results obtained from the study. The study revealed that users had leveled-off in their learning and experimentation and were using the CAD system in sub-optimal ways. The authors argue that this sub-optimal usage occurs because users have limited ways to learn better or different ways of executing tasks. The authors propose that CAD systems should provide active assistance, that is, intervene spontaneously with advice, assistance, and relevant information while the user interacts with the system. They conclude with some issues revealed by the study that should be considered when developing such active assistance.

title Visualization of Three-Dimensional Structure During Computer-Aided Design
source International Journal of Human-Computer Interaction 1995 v.7 n.1 pp. 37-56
summary The visual image presented to an engineer using a computer-aided design (CAD) system influences design activities such as decision making, problem solving, cognizance of complex relationships, and error correction. Because of the three-dimensional (3-D) nature of the object being created, an important attribute of the CAD visual interface concerns the various methods of presenting depth on the display's two-dimensional (2-D) surface. The objective of this research is to examine the effects of stereopsis on subjects' ability to (a) accurately transfer to, and retrieve from, long-term memory spatial information about 3-D objects; and (b) visualize spatial characteristics in a quick and direct manner. Subjects were instructed to memorize the shape of a 3-D object presented on a stereoscopic CRT during a study period. Following the study period, a series of static trial stimuli were shown. Each trial stimulus was rotated (relative to the original) about the vertical axis in one of six 36° increments between 0° and 180°. In each trial, the subject's task was to determine, as quickly and as accurately as possible, whether the trial object was the same shape as the memorized object or its mirrored image. One of the two cases was always true. To assess the relative merits associated with disparity and interposition, the two depth cues were manipulated in a within-subject manner during the study period and during the trials that followed. Subject response time and error rate were evaluated. Improved performance due to hidden surface is the most convincing experimental finding. Interposition is a powerful cue to object structure and should not be limited to late stages of design. The study also found a significant, albeit limited, effect of stereopsis. Under specific study object conditions, adding disparity to monocular trial objects significantly decreased response time. Response latency was also decreased by adding disparity information to stimuli in the study session.

title Internetwork Infrastructure Requirements for Virtual Environments
source NIl 2000 Forum of the Computer Science and Telecommunications Board, National Research Council, Washington, D.C., May 1995
summary Virtual environments (VEs) are a broad multidisciplinary research area that includes all aspects of computer science, virtual reality, virtual worlds, teleoperation and telepresence. A variety of network elements are required to scale up virtual environments to arbitrarily large sizes, simultaneously connecting thousands of interacting players and all kinds of information objects. Four key communications components for virtual environments are found within the Internet Protocol (IP) suite: light-weight messages, network pointers, heavy-weight objects and real-time streams. Software and hardware shortfalls and successes for internetworked virtual environments provide specific research conclusions and recommendations. Since large-scale networked are intended to include all possible types of content and interaction, they are expected to enable new classes of interdisciplinary research and sophisticated applications that are particularly suitable for implementation using the Virtual Reality Modeling Language (VRML).

title Sketching as a Solid Modeling Tool
source Third Symposium on Solid Modeling and Applications. C. Hoffmann and J. Rossignac. Salt Lake City, ACM: 313-321
summary This paper describes 'Quick-sketch', a 2d and 3d modeling tool for pen based computers. Users of this system define a model by simple pen strokes drawn directly on the screen of a pen-based PC. Lines, circles, arcs, or B-spline curves are automatically distinguished, and interpreted from these strokes. The system also automatically determines relations, such as right angles, tangencies, symmetry, and parallelism, from the sketch input, These relationships are then used to clean up the drawing by making the approximate relationships exact. Constraints are established to maintain the relationships in further editing. A constraint maintenance system, which is based on gestural manipulation and soft constraints, is employed in this system. Several techniques for sketch based definitions of solid objects are provided as well, including extrusion, surface of revolution, ruled surfaces and sweep. Feat ures can be sketched on the surfaces of 3d objects, using the same 2d- and 3d techniques. This way, objects of medium complexity can be sketched in seconds. The system can be used as a front-end to more sophisticated modeling, rendering or animation environments, serving as a hand sketching tool in the preliminary design phase.

Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 100-109.
summary Parasympathy is an interactive spatial experience operating as an extension of visitors’ minds. By integrating Artificial Intelligence (AI), wearable technologies, affective computing (Picard 1995; Picard 2003), and neuroscience, this project blurs the lines between the physical, digital, and biological spheres and empowers users’ brains to solicit positive changes from their spaces based on their real-time biophysical reactions and emotions.

The objective is to deploy these technologies in support of the wellbeing of the community especially when related to social matters such as inclusion and social justice in our built environment. Consequently, this project places the users’ emotions at the very center of its space by performing real-time responses to the emotional state of the individuals within the space.

summary Since 1993, we have experimented with Virtual Design Studios (VDS) as an on-going research project that investigates the combination of current computer-aided design (CAD), computer networks (Internet), and computer supported collaborative work (CSCW) techniques to bring together studentsat geographically distributed locations to work in a virtual atelier. In 1993 the theme of the first joint VDS project was in-fill housing for the traditional Chinese walled village of Kat Hing Wai in the New Territories north of Hong Kong, and our partners included MIT and Harvard in Boston (USA), UBC in Vancouver (Canada), and Washington University in St. Louis (USA). In 1994 we were joined by Cornell (USA) and Escola Tecnica Superior d’Arquitectura de Barcelona (Spain) to re-design Li Long housing in Shanghai, and 1995 added the Warsaw Institute of Technology (Poland) for the ACSA/Dupont competition to design a Center for Cultural and Religious Studies in Japan. The 1996 topic was an international competition to design a monument located in Hong Kong to commemorate the return of Hong Kong to Chinese sovereignty in 1997. Communication was via e-mail, the WorldWide Web with limited attempts at VRML, and network video. Several teaching and research experiments conducted through these projects have demonstrated the viability and potential of using electronic, telecommunications, and videoconferencing technologies in collaborative design processes. Results of these VDS have been presented at conferences worldwide, explained in journal papers and published in Virtual Design Studio, edited by J. Wojtowicz, published by HKU Press.

title Requirements for Virtual Design Review
source Architectural Research Quarterly 1(2), December
summary Requirements for Virtual Design Review: Fundamental Argument: This article deals primarily with the actual physical components of a virtual design review, and the difficulties associated with their integration. It is a rather refreshing approach to the problem of the virtual studio, in that it provides an empirical model of how the virtual and the real interact. Needless to say, there were numerous difficulties. 1. The reviewers and the students had to adapt to a new system of design review. Thus, traditional protocols and procedures may or may not work when dealing with a project in the virtual realm. The jurors and the students did become more comfortable as the jury progressed, but it is safe to say that those who went first most likely had a difficult and rather unhelpful session. 2. The technology itself was limited in what it could accomplish. The rate of transmissions across the line often hindered the review. Those students who used analog display, such as drawings or sketches, were not able to present these items effectively to remote viewers. The article does state that the virtual design review drew heavily upon the model of tradition review for its procedures. Was this the correct way of conducting the jury? With the introduction of technology into the process, one would think that there would be a significant shift in the model. Though the traditional model may be useful as a point of departure, we must critically engage the unique qualities that technology brings to the review. I would argue that a new model would need to be developed, whether it is a radical departure, a hybrid, or a modest adjustment to the existing model. For a traditional review, all one might need are a few push pins, a table for model display, and a surface upon which to pin his or her drawings. For the digital review, one requires monitors, computers, special lighting, video cameras, electrical outlets and phone jacks, and whatever else might be required to conduct a successful jury. It is in fact more akin to a television production than a traditional jury. The sheer complexity that technology inserts into the process can seem almost overwhelming. Yet if we can narrow our focus, find the essentials, by critically engaging those areas that will be affected by its introduction, then we can begin to imagine a true digital review.

title Message exchange in the building industry
source Automation in Construction 4 (2) (1995) pp. 91-100
summary A process model is described for exchanging information in the building industry. In this model participants send and receive messages. On receipt of a message an activity is executed if all required information is available. Otherwise a message will be sent to another participant to obtain the missing information. After execution of an activity a reply is sent with the desired data. In a building project an agreement is defined with all activities that will be executed by each of the participants. An executable implementation of the process model is built in ExSpect. In ExSpect the message exchange process can be simulated and analyzed for a specific building project.

summary Research has demonstrated that four-dimensional computer aided design (4D CAD), in which a three-dimensional (3D) CAD model is animated through time, is useful in helping professionals understand the construction schedule. However, cumbersome processes to update a 4D CAD model, which involve changing geometry representations, changing schedules and bar charts, linking the geometry to the scheduling information, and generating animations, may discourage professionals from using 4D CAD in actual construction projects. A software prototype implementing 4D CAD in a Web environment overcomes limitations of current 4D CAD tools. This software permits editing of the construction schedule over the Internet and shows the revised construction sequence visually on a Web browser using 3D computer graphics. This software is composed of a database on a server, Active Server Pages (ASP) scripts, and a Java applet that was developed using Java 3D Application Programming Interface (API) and Java JDBC. The Java applet retrieves the 4D model at the appropriate level of completion over the Internet and allows users to navigate around the model on the Web browser. Web4D visualization software can help professionals to expedite the schedule updating process by involving designers and constructors in collaborative decision- making.

summary The Creative Synthesis task devised by Finke and Slayton(1988) has been widely used as an experimental measure of mentalsynthesis, but previous studies have often failed to demonstrate anysignificant benefits of external support on participants’ performance.This paper discusses a study that examined novice and expert drawers’performance of synthesis using a modified stimuli set that was designedto increase the load on visuo-spatial working memory. The resultsshowed a significant increase in Transformational Complexity(Anderson & Hesltrup, 1993) of patterns produced by the expert groupwhile using sketching. It is argued that experts are more effective atusing sketching interactively to increase complexity, while novices relymore on using it as a simple memory aid.

LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

summary Typological design implies extensive knowledge of building types in order to design a building belonging to a building type. It facilitates the design process, which can be considered us a sequence of decisions. The paper gives an outline of a new approach in a course teaching typological knowledge through the medium of Knowledge-Based Systems programming. It demonstrates how Knowledge-Based Systems offer an appropriate structure for analysing the knowledge required to implement typological design. The class consists of third-year undergraduate students with no extensive previous programming experience. The implementation language is AutoLISP which operates in the AutoCAD environment. The building type used in the course is the office building. in order to become acquainted with both building type and programming in AutoLISP, information and instructions have been gathered and prestructured, including a worked out analysis and AutoLISP code. Office plans are generated through use of the Knowledge-Based System. They are encoded in the form of frames. At the end of the course the students will have learned the basics of Knowledge-Based Systems, have been introduced to programming these systems, have analysed and reflected upon the design process, and gained insight into a specific building type.

title Directions in modelling environments
source Automation in Construction 4 (3) (1995) pp. 173-187
summary Schema definition is a vital component in the computerised A/E/C projects. existing tools to manage this task are limited both in terms of the scope Of problems they can tackle and their integration with each other. This paper describes a global modellling and development environment for large modelling projects. This environment provides a total solution from initial design of schemas to validation, manipulation arid navigation through final models. A major benefit of the described system is the ability to provide multiple views of evolving schemas (or models) in both graphical and textual forms This allows modellers to visualise their schemas and instance models either textually or graphically as desired. The system automatically maintains the Conisistency of the informalion in these views even when modifications are made in other views. Simple and intuitive view navigation methods allow required information to he rapidly accessed. The environment supports strict checking of model instances and schemas in one of the major ISO-standardised modelling languages no used in product data technology. Ill this paper we show how such a modelling environment has been constructed for evaluation in the JOULE founded COMBINE project.
