title	Reflections on Computer-Supported Cooperative Design Systems
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 169-180
summary	Computer-supported cooperative work has come to signify a process by which a computer system supports the activities of geographically dispersed participants and enables them to share ideas and artefacts. This paper aims to dispel this unified approach to the definition of and in turn the design of aids to cooperative work. The paper starts by surveying the history of the field of computer-supported cooperative work and design. Then, the paper presents three tasks and their associated aids. The first system helps designers to create and discuss a hierarchical building program and share schematic drawings. The second system allows a jury to anonymously review a set of submissions. The third system allows a hierarchically organised group of participants to search, retrieve, organise and share a set of digital media assets. All systems are web-based and use the same underlying object-oriented technology. The paper provides a brief case study that describes the main features of the three pieces of software as an example of the need for a variety of approaches in the support of cooperative work and design. The paper concludes by advocating an object-oriented, domain-specific approach to creating computer-supported cooperative systems based on the analysis of the task at hand.

title	The Potential of Non-Manifold Topology in the Early Design Stages
doi	https://doi.org/10.52842/conf.acadia.2015.381
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 381-493
summary	The importance of decisions made during the early design stages has prompted researchers to advocate the use of building performance simulation (BPS) during that stage. This paper investigates non-manifold topology (NTM) as a novel approach to 3D modelling that has the potential to be highly compatible with the early design stages and with the input requirements for BPS. The proposed approach avoids the process of simplifying polyhedral models produced by Building Information Modelling (BIM) software to conduct BPS. In particular, NTM allows for a clear segmentation of a building, unambiguous space boundaries, and perfectly matched surfaces and glazing subsurfaces. The NTM approach was tested through a software prototype that integrates 3D modelling software and an energy simulation engine.

summary	Non-manifold topology (NMT) allows the user to construct light-weight conceptual spatial architectural models which define the overall enclosure and the internal cellular division within that enclosure. The objective of this workshop is to give participants hands-on opportunities with a new software library that we have been developing under a research grant from the Leverhulme Trust. On the first day, the concepts of non-manifold topology will be introduced, including non-regular modelling operations. On the second day, we will introduce two plug-ins, which have been interfaced to our NMT tools: a) building energy simulation using OpenStudio and EnergyPlus and b) structural analysis software.

title	The Role of Computers in Synchronous Collaborative Design
source	Proceedings of the 14th International Congress on Cybernetics. Namur, Belgium: International Association for Cybernetics, 1995, pp. 71-76
summary	In this paper we discuss the role of computers in supporting real-time synchronous design among geographically dispersed team members using the global network of computers known as the Internet. To enable efficient and functional synchronous design activity, we advocate a new generation of design-oriented software that combines collaboration technologies with a meaningful and parsimonious representation scheme. We are particularly interested in supporting the early design phases, wherein many of the most important decisions are made and collaboration is most important. These activities are crucial to the evolution and quality of the final design, and they are receptive to and can benefit from computer support. Furthermore, these are precisely the areas where current CAD systems are weakest. As a general theoretical direction, our emphasis is not on integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. Our first experimental phase involved the simultaneous development and testing of prototypes for a Synchronous Collaborative Design Environment (SYCODE) on heterogeneous computer systems at two geographically dispersed sites. The applications were developed independently, based on a verbal description of protocols, with minimal sharing of actual source code. Though their user interfaces and implementation details are different, these prototypes allow multiple users to share a virtual design space - both within and between the remote sites - in which to create and manipulate architectural elements.

title	Beyond the Shared Whiteboard: Issues in Computer Supported Collaborative Design
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 719-725
summary	This research focuses on combining the rich representations of computer-aided design systems with current collaboration technologies to support distributed design processes. Our emphasis is not on concurrent multi-user access to integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. We have developed a prototype for a Synchronous Collaborative Design System (SYCODE) that enables geographically dispersed designers to share common representations even when using different hardware platforms. The limitations of the existing network infrastructure have compelled its to devise a meaningful and parsimonious representation scheme and to semantically define pending and confirmed actions.

title	The synergy of non-manifold topology and reinforcement learning for fire egress
doi	https://doi.org/10.52842/conf.ecaade.2019.2.085
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 85-94
summary	This paper illustrates the synergy of non-manifold topology (NMT) and a branch of artificial intelligence and machine learning (ML) called reinforcement learning (RL) in the context of evaluating fire egress in the early design stages. One of the important tasks in building design is to provide a reliable system for the evacuation of the users in emergency situations. Therefore, one of the motivations of this research is to provide a framework for architects and engineers to better design buildings at the conceptual design stage, regarding the necessary provisions in emergency situations. This paper presents two experiments using different state models within a simplified game-like environment for fire egress with each experiment investigating using one vs. three fire exits. The experiments provide a proof-of-concept of the effectiveness of integrating RL, graphs, and non-manifold topology within a visual data flow programming environment. The results indicate that artificial intelligence, machine learning, and RL show promise in simulating dynamic situations as in fire evacuations without the need for advanced and time-consuming simulations.

title	Integrating Databases, Objects and the World-Wide Web for Collaboration in Architectural Design
source	Proceedings of the focus symposium: World Wide Web as Framework for Collaboration in conjunction with the 11th International Conference on Systems Research, Informatics and Cybernetics, The International Institute for Advanced Studies in Systems Research
summary	Architectural design requires specialized vertical knowledge that goes beyond the sharing of marks on paper or the multi-casting of video images. This paper briefly surveys the state-ofthe- art in groupware and outlines the need for vertical and integrated support of synchronous and asynchronous design collaboration. The paper also describes a software prototype (WebOutliner) under development that uses a three-tier persistent object-oriented, web-based technology for a richer representation of hierarchical architectural artifacts using Apple’s WebObjects technology. The prototype contributes to earlier work that defined a framework for a shared workspace consisting of Participants, Tasks, Proposals, and Artifacts. These four elements have been found through observation and analysis to be adequate representations of the essential components of collaborative architectural design. These components are also hierarchical which allows users to filter information, copy completed solutions to other parts of the program, analyze and compare design parameters and aggregate hierarchical amounts. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. In addition, the prototype integrates this technology with Java tools for ubiquitous synchronous web-based access. The prototype uses architectural programming (defining the spatial program of a building) and early conceptual design as examples of seamlessly integrated groupware applications.

title	Visualizing and Investigating Architectural Space Using Spherical Panoramic Imaging
source	Emerging Technologies and Design: The Intersection of Design and Technology, Proceedings of the 2000 ACSA Technology Conference, Massachusetts Institute of Technology, Cambridge, Massachusetts, July 14-17, 2000
summary	This paper reports on the use of immersive spherical imaging techniques to document, visualize and investigate architectural space. This technology can be used in the classrooms and design studios to augment traditional instructional and design investigation tools. As opposed to cylindrical imaging found in the popular QuickTime VR format, spherical imaging provides a 360-degree view in all directions – horizontally and vertically. The ability to capture and display a full sphere can be crucial for many interior architectural spaces. Spherical panoramas can originate from real, synthetic or hybrid source images. In addition to the ability to embed links to web pages or other panoramas, a unique feature of this technology allows the viewer to navigate through a scene as well as pause at any point and view the space in all directions. In addition, the technology allows the user to sketch over the scene in an intelligent manner such that the sketched artifacts rotate correctly when the target view shifts. The software also integrates with collaborative tools to allow synchronous viewing of shared panoramas over the Internet. These features allow for a truly immersive and interactive experience of the space that can be quite useful in a design studio setting. Finally, this paper describes ongoing efforts to integrate this technology with an interactive web-based, databasedriven virtual slide tray system for the storage, sorting, and display of multimedia content.

title	WebOutliner: A Web-Based Tool for Collaborative Space Programming and Design
doi	https://doi.org/10.52842/conf.acadia.2000.195
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 195-201
summary	This paper discusses a web-based tool that allows members of a design team to collaboratively specify a hierarchical spatial program for an architectural project. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. Given that these components are hierarchical allows users to filter information, analyze and compare design parameters and aggregate hierarchical amounts in realtime. Furthermore, the software goes beyond outlining functions to support synchronous collaborative design by linking each item in the spatial program to a detail page that allows file uploading, realtime group marking of images, and textual chat. Thus, the software offers a seamless transition from the largely asynchronous definition of an architectural program to synchronous collaboration. In addition, and in contrast to commercially available groupware, the software allows multiple collaboration sessions to run at the same time. These sessions are artifact-based in the sense that they get automatically initiated once participants visit the same architectural space in the program hierarchy. The software employs a three-tier object-oriented, web-based scheme for a richer representation of hierarchical artifacts coupled with a relational database for server-side storage. The prototype integrates this technology with Java-based tools for synchronous web-based collaboration.

title	The Vista System: A Virtual Slide Tray Archive
doi	https://doi.org/10.52842/conf.acadia.2001.x.o7g
source	ACADIA Quarterly, vol. 20, p. 2
summary	ViSTA is a digital asset management and display system designed for education. The system enables instructors to search a database of digital assets, select the ones they want and save them in sortable virtual slide trays. They can then use those trays for in-class presentations as well as allowing registered students to view them at will from any internet-connected computer. Students register for courses in the ViSTA system through a special code issued by the instructor. Once registered, their ViSTA homepage automatically displays the courses they are registered for and the associated trays for that particular course. Students can also create and modify their own personal trays organized in any fashion they want. These trays can be used for reference, studying for an exam, or for presentation purposes. The ViSTA system helps administrators and faculty manage the digital collection, the courses, the trays, and the user accounts.

title	Digital Tectonics: The intersection of the physical and the virtual
doi	https://doi.org/10.52842/conf.acadia.2004.256

summary	The advent of automated manufacturing processes and the possibility of directly translating virtual creations into physical artifacts brought forth the possibility of exploring a digital tectonic: the poetics of digitally conceived, structurally clarified and directly manufactured architecture. CAD/CAM equipment is being rapidly installed in schools of architecture without much thought given to its effect on the tradition of tectonics. To investigate these effects, this paper includes discussions of the tradition of architectural tectonics and of more recent works that illustrate the possibilities of digital tectonics. This discussion is followed by a brief survey of some of the research in the area of analog/digital pedagogy. Additionally, two experiments were conducted in an academic course setting that explored analog, digital, and hybrid approaches to the creation of architectural artifacts. The physical and virtual artifacts from the two experiments were analyzed and commonalities and differences were discerned. The research project reported in this paper further clarifies the notion of digital tectonics as the poetics of digitally constructed assemblages, and points to possible pitfalls of using CAD/CAM equipment that disregard the materiality of components and their interconnectedness.

title	Augmenting Architecture Through Desktop Manufacturing
source	International Journal of Architectural Computing vol. 10 - no. 2, 163-184
summary	Personal desktop manufacturing, with its roots in hacker culture, is on the cusp of exploding into the main stream due to the advent of affordable personal 3D printers.This paper is an exploration of these advances in desktop manufacturing technology and their impact on our relationship with products and the built environment.The paper draws parallels to the personal computing and desktop publishing revolutions that offer clues to the future of personal desktop manufacturing. Four major themes have emerged from this exploration: Personal empowerment, remote printing and collaboration, full-scale digital construction, and, most intriguingly, architectural prosthetics. Based on an open-source philosophy and creative commons licensing, desktop manufacturing is redefining our relationship with large manufacturers and is beginning to convert us back from a consumerist culture into a creator one.

summary	We have conducted a series of interdisciplinary studios that partner students in the School of Architecture with peers in the College of Computing Sciences, with two principal goals: to foster creativity in the development of information technology, and conversely, to support creativity through information technology. Our studio project focuses on ubiquitous social computing as a topic of interest to both communities that requires their collaboration to realize a physical implementation. There are administrative as well as cultural hurdles in conducting such a studio. To assess the impact of the pedagogical approach, we employed qualitative observations as well as quantitative survey data. Best results depend on achieving a degree of parity in studio experience across disciplines.

title	Geometry, Light, and Cosmology in the Church of Hagia Sophia
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 304-319
summary	Designed by a physicist and a mathematician, the Hagia Sophia church in Istanbul, Turkey acted as an experimental test case in which advanced knowledge of geometrical constructs, sophisticated understanding of light behavior, and religious and cosmological beliefs combined to create a magnificent structure. While some of its design concepts are known, many remain hidden. Earthquakes have demolished parts of the church—such as the original dome. Researchers have in the past misinterpreted their observations and perpetuated false conclusions. Lastly, the lack of digital tools has until now prevented verification and analysis of prior findings. In this paper, we integrate traditional historical research, parametric digital analysis, and lighting simulation to analyze several aspects of the church. In particular, we focus on the geometry of the floor plan, the geometry of the apse, and light behavior in the original dome. Our findings point to the potential of digital tools in the discovery of a structure's hidden features and design rules.

title	Integrated Component-based Computer Design Modeling System: The Implications of Control Parameters on the Design Process
source	New Jersey Institute of Technology, Newark, NJ Graduate Thesis - Master's Program College of Architecture
summary	The design process is dependent on a clear order of integrating and managing all of the control parameters that impact on a building's design. All component elements of a building must be defined by their: Physical and functional relations; Quantitative and calculable properties; Component and/or system functions. This requires a means of representation to depict a model of a building that can be viewed and interpreted by a variety of interested parties. These parties need different types of representation to address their individual control parameters, as each component instance has specific implications on all of the control parameters. Representations are prepared for periodic design review either manually through hand-drawn graphics and handcrafted models; or with the aid of computer aided design programs. Computer programs can profoundly increase the speed and accuracy of the process', as well as provide a level of integration, graphic representation and simulation, untenable through a manual process. By maintaining a single control model in an Integrated Component-based Computer Design Modeling System (ICCDMS), interested parties could access the design model at any point during the process. Each party could either: 1. Analyze individual components, or constraints of the model, for interferences against parameters within that party's control; or 2. Explore design alternatives to modify the model, and verify the integration of the components or functions, within the design model, as allowable in relation to other control parameters.

title	Automatic Floorplan Design Using PIAF
source	August, 1988. 36 p. : ill. tables
summary	This paper presents PIAF (a Package for Intelligent and Algorithmic Floorplanning), developed at Sydney University Electrical Engineering (SUEE) for use in custom integrated circuit design. Floorplanning plays a crucial role in the design of custom integrated circuits. When design is approached in a top-down fashion, the function to be implemented on silicon is first decomposed in a conceptual phase into a Functional Block Diagram (FBD). This FBD has a 'blocks and buses' structure where blocks represent sub- functions and buses represent the interconnections that carry data and other information between blocks. The decomposition of the function into sub-functions is hierarchical and aims at reducing the complexity of the design problem. When the FBD is known, the floorplanning process may be performed. When this task is performed manually, the designer searches for a relative placement of the blocks and for an area and shape for each block to minimize the overall chip layout area while at the same time meeting design constraints such as design tool limitations, interconnection characteristics and technological design rules. PIAF is a knowledge-based system (KBS) that has been developed at SUEE during the last four years. It relies on a strategy that partitions the floorplanning task in a way that allows efficient use of heuristics and specialized design knowledge in the generation and pruning of the solution space. This paper presents the operation of PIAF and discusses several implementation issues including; KBS structure, knowledge representation, knowledge acquisition, current context memory design, design quality factors and explanation facility. This paper uses a running example to present the operation of each PIAF's KBS-based solving phases

summary	An existing café and multi-functional space at the School of Design of the Hong Kong Polytechnic University has been linked to a “twin” in the form of an online-accessible environment. Using arrays of sensors, displays and other interfaces, channels of communication are established between the virtual space and the physical space, enabling on-site visitors to the café and online visitors to the project website to participate in a shared spatial experience. The project explores ways in which digital technologies can serve to enhance and enrich the experience of spatiality and human social interaction in space(s). The paper explains the design of the modes of communication between the two spaces, outlining the theory and genesis of the project and discussing the issues and principles that come into play in the design an realization of such spaces, such as the interplay between the three-dimensionality of the physical space and the two-dimensional picture-plane based monitor interface through which the website is experienced, and strategies for the transmission of spatial experience within the strictures of commonly-available hardware and software interfaces.

summary	Keynote Paper - We are all involved in design.Besides being the (sub)conscious recipients of all sorts of design driven activities, we are professionally concerned with products of design and acts of designing, either as practitioners or as academics, in some cases as both… As someone who was trained as a designer, drifted into design teaching and presently attempts to combine composition research with design practice, I feel there is a need to bridge the cultural gap between design and design research. I intend to put forward the case for more designerly approaches in the study of design. In this context I would like to discuss perspectives for design driven studies by considering the following ensemble of aspects:- the matter of shifting attitudes to design in a scientific context; - the necessity of expanding the scope of instruments of design in relation to methods and insights. - the furthering of opportunities for networks aimed at bringing out and communicating findings concerning different aspects of design.It is on the topic of interaction, between the targeted creativity of designing on the one hand and the open minded search for relevant knowledge, insights and applications on the other, that I would like to dwell. Furthermore, I hope to provoke some thoughts – and hopefully responses – concerning the roles of computer based applications in such studies. What kinds of impulses have computer technologies offered, should they perhaps have offered and indeed might they still be able to offer in this field? I would like to by take a critical look back and try to turn things around, towards a possible view forward…

title	Using Formal Specifications in the Design of a Human-Computer Interface
source	Communications of the ACM April, 1983. vol. 26: pp. 259-264 : diagrams. includes bibliography.
summary	Formal specification techniques are valuable in software development because they permit a designer to describe the external behavior of a system precisely without specifying its internal implementation. Although formal specifications have been applied to many areas of software systems, they have not been widely used for specifying user interfaces. In the Military Message System project at the Naval Research Laboratory, the user interfaces as well as the other components of a family of message systems are specified formally, and prototypes are then implemented from the specifications. This paper illustrates the specification of the user interface module for the family of message systems. It then surveys specification techniques that can be applied to human-computer interfaces and divides the techniques into two categories: those based on state transition diagrams and those based on BNF. Examples of both types of specifications are given. Specification notations based on state transition diagrams are preferable to those based on BNF because the former capture the surface structure of the user interface more perspicuously. In either notation, high-level abstraction for describing the semantics of the user interface is needed, and an application-specific one is used here

source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	In most design practices there is a division between the generation of information to describe buildings and the production of information to construct them. Today architects are in charge of the design of the building (aesthetics) while the contractor is accountable for the means of construction (tectonics). The advent of digital technologies within the field of architecture however has begun to cause and will continue to cause fundamental changes within the AEC industry. The Paper describes a possible scenario where a Bottom – Up, part to whole approach to architecture can be adopted using the freedom afforded by Parametric Design within the CAD-CAM environment. This approach is explored through the design of a smart block in concrete that is integrated into a wall system.
