title Toward a procedure of computer simulation in the restoration of historical architecture
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 field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title Orientation, Identification, Representation - Space and Perception in Architecture

summary Perception is essential to being in the world — through perception we are in the world. Perception is our way to understand reality and to acquire knowledge of it and be in interaction with the environment. Experiencing architecture is based on perception: the spatial orientation, identification and representation which together make possible our environmental experience. Architecture is not only seeing, but also experiencing. Environmental endoscopy makes it possible to study the environmental orientation, the spatial elements of the environment, but the identification and the representation which are included essentially in the overall perception of the environment presuppose the actual experience of the environment. This presentation discusses all these three levels of the spatial experience. In architecture, space can be discussed in many different ways: we can talk about, for example, architectural space that includes inside and outside space; we can discuss urban space that includes the physical structure of the whole built environment or we can talk about what has been called existential space, that includes the relationship between man and his physical environment. In this presentation space is considered in its wide, experience based meaning: space as the environment of perception, the interaction between man and space, or as a kind of cognitive space theory. Most essential in this discussion is the experience of place, the feeling of place, and its origins, since place is the most unique experience of space, it is man’s deepest experience of the environment.

title Understanding the AR-VR Based Architectural Design Workflow among Selected Danish Architecture Practices
source Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 381–388

summary Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

title Common Illumination between Real and Computer Generated Scenes
source Proceedings Graphics Interface '93, pp. 254-262, 1993
summary The ability to merge a real video image (RVI) with a computer- generated image (CGI) enhances the usefulness of both. To go beyond "cut and paste" and chroma-keying, and merge the two images successfully, one must solve the problems of common viewing parameters, common visibility and common illumination. The result can be dubbed Computer Augmented Reality (CAR). We present in this paper techniques for approximating the common global illumination for RVIs and CGIs, assuming some elements of the scene geometry of the real world and common viewing parameters are known. Since the real image is a projection of the exact solution for the global illumination in the real world (done by nature), we approximate the global illumination of the merged image by making the RVI part of the solution to the common global illumination computation. The objects in the real scene are replaced by few boxes covering them; the image intensity of the RVI is used as the initial surface radiosity of the visible part of the boxes; the surface reflectance of the boxes is approximated by subtracting an estimate of the illuminant intensity based on the concept of ambient light; finally global illumination using a classic radiosity computation is used to render the surface of the CGIs with respect to their new environment and for calculating the amount of image intensity correction needed for surfaces of the real image. An example animation testing these techniques has been produced. Most of the geometric problems have been solved in a relatively ad hoc manner. The viewing parameters were extracted by interactive matching of the synthetic scene with the RVIs. The visibility is determined by the relative position of the "blocks" representing the real objects and the computer generated objects, and a moving computer generated light has been inserted. The results of the merging are encouraging, and would be effective for many applications.

title Understanding Shared Space for Informal Interaction among Geographically Distributed Teams
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 41-54.
summary In a design project, much creative work is done in teams, thus requires spaces for collaborative works such as conference rooms, project rooms and chill-out areas. These spaces are designed to provide an atmosphere conducive to discussion and communication ranging from formal meetings to informal communication. According to Kraut et al (E.Kraut et al., 1990), informal communication is an important factor for the success of collaboration and is defined as “conversations take place at the time, with the participants, and about the topics at hand. It often occurs spontaneously by chance and in face-to-face manner. As shown in many research, much of good and creative ideas originate from impromptu meeting rather than in a formal meeting (Grajewski, 1993, A.Isaacs et al., 1997). Therefore, the places for informal communication are taken into account in workplace design and scattered throughout the building in order to stimulate face-to-face interaction, especially serendipitous communication among different groups across disciplines such as engineering, technology, design and so forth. Nowadays, team members of a project are not confined to people working in one location but are spread widely with geographically distributed collaborations. Being separated by long physical distance, informal interaction by chance is impossible since people are not co-located. In order to maintain the benefit of informal interaction in collaborative works, research endeavor has developed a variety ways to shorten the physical distance and bring people together in one shared space. Technologies to support informal interaction at a distance include video-based technologies, virtual reality technologies, location-based technologies and ubiquitous technologies. These technologies facilitate people to stay aware of other’s availability in distributed environment and to socialize and interact in a multi-users virtual environment. Each type of applications supports informal interaction through the employed technology characteristics. One of the conditions for promoting frequent and impromptu face-to-face communication is being co-located in one space in which the spatial settings play as catalyst to increase the likelihood for frequent encounter. Therefore, this paper analyses the degree to which sense of shared space is supported by these technical approaches. This analysis helps to identify the trade-off features of each shared space technology and its current problems. A taxonomy of shared space is introduced based on three types of shared space technologies for supporting informal interaction. These types are named as shared physical environments, collaborative virtual environments and mixed reality environments and are ordered increasingly towards the reality of sense of shared space. Based on the problem learnt from other technical approaches and the nature of informal interaction, this paper proposes physical-virtual shared space for supporting intended and opportunistic informal interaction. The shared space will be created by augmenting a 3D collaborative virtual environment (CVE) with real world scene at the virtual world side; and blending the CVE scene to the physical settings at the real world side. Given this, the two spaces are merged into one global structure. With augmented view of the real world, geographically distributed co-workers who populate the 3D CVE are facilitated to encounter and interact with their real world counterparts in a meaningful and natural manner.

title A Tool for Typological Analysis
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi https://doi.org/10.52842/conf.ecaade.1993.x.q0g
summary Any design problem is faced drawing from the architect's knowledge both case knowledge and general knowledge. One type of the latter is abstracted from a multiplicity of cases of which the common features are recognised in such a way as to single out a prototype representing in the best way a class of architectural objects. If applied to a set of residential buildings and to the flats in them the analysis is typological and it is one of the fundamental ways of acquiring general knowledge to be used to face design problems. The tool we present is aimed at such a type of analysis and is based on the idea that it possible to acquire qualitative knowledge through the statistical analysis of measurable characteristics of the examined architectural objects. It has been tested by applying it to the typological analysis of a set of flats of illegal buildings in Sicily. The procedure is organised in two main phases. The first one consists in a series of elaborations performed during the reading of architectural organism; the second one consists in a series of statistical analyses on the results (characteristic variables) of the first.

title Design Tool Integration: Model Flexibility for the Building Profession
source Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title Knowledge-based Stair Design
source Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 163-171
doi https://doi.org/10.52842/conf.acadia.1993.163
summary The application of computer--based technique to support architectural design has often concentrated on matters of representation. Typically, this means computer-aided drafting, and less frequently, computer-aided modeling and visualization. The promise of new computer-based tools to support the process of design has thus far failed to produce any significant tool that has had a widespread impact on the architectural profession. Most developments remain in university based research labs where they are used as teaching instruments in CAD courses or less often in design studios. While there are many reasons for this lack of dissemination, including a reluctance on the part of the architectural profession itself, the primary obstacles deal with difficulties in explicating design knowledge, representing this knowledge in a manner that can be used for design, and providing an intuitive and effective user interface, allowing the designer to easily use the tool for its intended purpose.

This study describes a system that has been developed to address a number of these issues. Based on research findings from the field of Artificial Intelligence which expounds on the need for multiple techniques to represent any complex area of knowledge, we have selected a particular approach that focuses on multiple techniques for design representation. We review this approach in depth by considering its many facets necessary when implementing a knowledge-based system. We then partially test the viability of this approach through a small case study, implementing a knowledge-based system for designing stairs. While this effort only deals with a small part of the total design process, it does explore a number of significant issues facing the development of computer-based design assistants, and suggests several techniques for addressing these concerns.

summary This paper addresses communication issues, which are crucial in any implementation of distributed design environments. Communication needs are specified and implemented in a prototype based on a modular knowledge-based approach for simulation of a distributed multi-user system. The results of these simulations are reported, which show communication to be scalable as the numbers of applications and the size of the design increases. Finally, the implications of the results on real distributed systems are discussed.

title The Evolution of an Interface for Choreographers Evolving Design
source Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems 1993 pp. 115-122
summary This paper describes the evolution of the interface to Life Forms, a compositional tool for the creation of dance choreography, and highlights some of the important lessons we have learned during a six year design and implementation period. The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected as necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version. The choreography and composition of a dance is a complex synthesis task which has much in common with design. Thus, the lessons learned here are applicable to the development of interfaces to such applications as computer aided design.

title SOME EPISTEMOLOGICAL CONCERNS REGARDING ARTIFICIAL INTELLIGENCE AND KNOWLEDGE-BASED APPROACHES TO ARCHITECTURAL DESIGN - A RENEWED AGENDA
source Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 155-162
doi https://doi.org/10.52842/conf.acadia.1993.155
summary It has been noted that designers - when confronted with computers - have, by and large, refused to accept the introduction of apparently new design methodologies, and it has been speculated that this is the result of a failure of those methodologies to address the cognitive processes which take place in the course of designing. This position is somewhat suspect in that such innovations as computer-aided drafting -which also fail to recognize these processes have been widely accepted. It is perhaps more likely that the lack of acceptance results from a perception on the part of designers that the new methodologies either do not reflect some or all of those concerns that designers consider fundamental to design, or that they actively interfere with the designer's ability to accomplish what he/she sees as the goals of design. Given that the application of artificial intelligence and related work to architecture is still in its infancy, all of this suggests the need for a reassessment of the role of computing in design in order to clarify and strengthen those roles deemed appropriate.

Two approaches to the integration of artificial intelligence and knowledge-based systems into architectural design practice are currently dominant. One attempts to create systems which can on their own produce designs, the other provides intelligent support for those doing design. It was, in part, the recognition of limitations in the ability of traditional CAD systems and building modelers to reflect what designers actually do that led to explorations into the idea of intelligent assistants. Development of such assistants was aided by research into the act and process of design through protocol and other studies. Although some work is currently being done in the development of artificial intelligence and knowledge based applications in architecture, and work continues to be done on the study of design methodologies, the bulk of available information in each of these areas remains in the realm of design disciplines related to but outside of architecture and do not reflect the explicit role of architectural design in the embodiment and expression of culture.

The relationship of intelligence to culture has resulted in some skepticism regarding the ultimate capacity of neural nets and symbolically programmed computers in general. Significant work has been done questioning the rational tradition in computer development for its failure to address phenomena which are not easily subject to scientific analysis. Further skepticism regarding the role of artificial intelligence and knowledge-based or expert systems in architectural design has been emerging recently. Such criticism tends to focus on two issues: the nature of drawing as an activity which involves both the generation and interpretation of graphic artifacts, and the nature of the human designer as an active agent in the design process.

summary Maintaining knowledge of current position and orientation is frequently a problem for people in virtual environments. In this paper we present a toolset of techniques based on principles of navigation derived from real world analogs. We include a discussion of human and avian navigation behaviors and show how knowledge about them were used to design our tools. We also summarize an informal study we performed to determine how our tools influenced the subjects' navigation behavior. We conclude that principles extracted from real world navigation aids such as maps can be seen to apply in virtual environments.

summary Modelling knowledge and data in CAD/CAM applications is complex because different goals and contexts have to be taken into account. This complexity makes particular demands upon representation formalisms. Today many modelling tools are based on record structures. By analyzing the requirements for a product model of a portal structure in steel, this paper shows that in many situations record structures are not well suited as a representation formalism for storing knowledge and data in CAD/CAM applications. This is illustrated by performing a knowledge-level analysis of the knowledge and data generated in the design and manufacturing process of a portal structure in steel.

doi https://doi.org/10.52842/conf.acadia.1998.008
summary The last thirty years have seen the development of powerful new tools for architects and planners: CAD, 3D modeling, digital imaging, geographic information systems, and real time animated walkthroughs. That’s just the beginning. Based on our experience with CAD tools, analysis of design practice, and an understanding of computer hardware and software, we’re out to invent the next generation of tools. We think architects should be shakers and makers, not just consumers, of computer aided design. We started the Sundance Lab (for Computing in Design and Planning) in 1993 with a few people and machines. We’ve grown to more than a dozen people (mostly undergraduate students) and a diverse interdisciplinary array of projects. We’ve worked with architects and planners, anthropologists, civil engineers, geographers, computer scientists, and electrical engineers. Our work is about the built environment: its physical form and various information involved in making and inhabiting places. We cover a wide range of topics – from design information management to virtual space, from sketch recognition to design rationale capture, to communication between designer and computer. All start from the position that design is a knowledge based and information rich activity. Explicit representations of design information (knowledge, rationale, and rules) enables us to engage in more intelligent dialogues about design. The following describes some of our projects under various rubrics.

summary Nature as complete entity having existed before us, having produced us, of which we are a part of and which reaches far beyond us and our knowledge stands both for productivity and product, for stones, earth, water, air, plants, animals, human beings, for energy as such. On account of his activity and his intellectual powers and faculties the human being represents the center of this interrelation comprising his vital space, being perceived by him either consciously or unconsciously, the structure and formation of which he changes, which in turn, however, significantly codetermines his behavior and also his development. Spatial effect analysis and spatial impact analysis take the cross- linked interrelations of nature into account and thus the correlated diverse interactions by means of integral representation, determine the direct and indirect as well as the immediate and mediate decisions as to space and furnish us with decision-conclusions by means of modifications. Based on the all-in-all outlook encompassing nature- mankind-space spatial impact also means in particular compatibility within systems giving due regard to the factor time. The following topics are treated within the framework of research: (1.) Elaboration of a methodical framework regarding research and development in the field of multimedia-implementation for environmental planning. (2.) Preparative work concerning implementation areas of multimedia focussing on urban & regional planning and architecture. (3.) Planning process and planning levels,furthermore in the fields of information and decision process and accompanying verification. (4.) Optimizing interaction of multimedia and environmental simulation. (5.) Definition of research- and development-requirements as far as subject-specific and EDP-technical aspects are concerned. (6.) Structurizing of projects regarding realization of framework of research.

summary This paper shows work exemplifying the further extent of computer capabilities in the field of design. The work stems from a belief that for computers to be used effectively within the architectural profession their utility must stretch far beyond the process of description of geometric data, but be incorporated in the fundamental roots of design: that of conceptual design. Computers can be used to access the knowledge we have and then formulate this knowledge into a working language of design. Computers can be used to generate space and form in accordance with any relationship the designer may choose to set. This allows them to be used from the very conception of design. It is only by working from the very beginning, the very basis of the design of a building that we can fully develop the integration of computers in the construction industry. The work undertaken sets out primarily to explore one of the ways computers could be used in the field of architectural design. In recognition that an important byproduct of any design search is the enhanced understanding of the problem itself, the work was directed towards a particular project. This allowed each stage of thought to be to be considered as it arose and subsequently incorporated into the design model. The work does not attempt to automise the design process but simply tries to explore some of the opportunities offered by computers and see if they can be easily incorporated into the design process offering design solutions that may not otherwise have been considered. The exploration resulted in a simple design process model that incorporates the more accessible and useful aspects of computer technology.

title Analogy, Exploration and Generalization: Three Activities for Knowledge-Based Architectural Design Systems
source CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 255-272
summary We propose in this article a system architecture based on reasoning through analogy with past cases or situations. Starting with a project and a sketch provided by the user, the system locates analogous situations in the past and uses these to improve a problem's description. A sufficiently improved description will in turn activate a constraint-satisfaction mechanism. Previous situations are stored in a memory bank of objects that match the description of past problems to the generic descriptions of past solutions. Three mechanisms can be distinguished within the system: an analogy mechanism collects hypotheses about the variables and constraints to be satisfied in past situations, an exploratory mechanism searches through the solution space, a generalizing mechanism looks at experiences and memorizes only what is needed to collect hypotheses.

title Case-Based Structural Design - using weakly structured product and process information
source Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

title Will Media Influence Learning? Reframing the Debate
source Educational Technology Research and Development (1):1-31
summary This article addresses the position taken by Clark that media do not influence learning under any conditions. The article reframes the questions raised by Clark to explore the conditions under which media will influence learning. Specifically, it posits the need to consider the capabilities of media, and the methods that employ them, as they interact with the cognitive and social processes by which knowledge is constructed. This approach is examined within the context of two major media-based projects, one which uses computers and the other video. The article discusses the implications of this approach for media theory, research, and practice.
