    Designing a novel virtual collaborative environment to support collaboration in design review meetings

    Project review meetings are part of the project management process and are organised to assess progress and resolve any design conflicts to avoid delays in construction. One of the key challenges during a project review meeting is to bring the stakeholders together and use this time effectively to address design issues as quickly as possible. At present, current technology solutions based on BIM or CAD are information-centric and do not allow project teams to collectively explore the design from a range of perspectives and brainstorm ideas when design conflicts are encountered. This paper presents a system architecture that can be used to support multi-functional team collaboration more effectively during such design review meetings. The proposed architecture illustrates how information-centric BIM or CAD systems can be made human- and team-centric to enhance team communication and problem solving. An implementation of the proposed system architecture has been tested for its utility, likability and usefulness during design review meetings. The evaluation results suggest that the collaboration platform has the potential to enhance collaboration among multi-functional teams

    A framework of web-based conceptual design

    A web-based conceptual design prototype system is presented. The system consists of four parts which interpret on-line sketches as 2D and 3D geometry, extract 3D hierarchical configurations, allow editing of component behaviours, and produce VRML-based behavioural simulations for design verification and web-based application. In the first part, on-line freehand sketched input is interpreted as 2D and 3D geometry, which geometrically represents conceptual design. The system then infers 3D configuration by analysing 3D modelling history. The configuration is described by a parent–child hierarchical relationship and relative positions between two geometric components. The positioning information is computed with respect to the VRML97 specification. In order to verify the conceptual design of a product, the behaviours can be specified interactively on different components. Finally, the system creates VRML97 formatted files for behavioural simulation and collaborative design application over the Internet. The paper gives examples of web-based applications. This work forms a part of a research project into the design and establishing of modular machines for automation manufacture. A consortium of leading automotive companies is collaborating on the research project

    Supporting Computer-supported collaborative work (CSCW) in conceptual design

    In order to gain a better understanding of online conceptual collaborative design processes this paper investigates how student designers make use of a shared virtual synchronous environment when engaged in conceptual design. The software enables users to talk to each other and share sketches when they are remotely located. The paper describes a novel methodology for observing and analysing collaborative design processes by adapting the concepts of grounded theory. Rather than concentrating on narrow aspects of the final artefacts, emerging “themes” are generated that provide a broader picture of collaborative design process and context descriptions. Findings on the themes of “grounding – mutual understanding” and “support creativity” complement findings from other research, while important themes associated with “near-synchrony” have not been emphasised in other research. From the study, a series of design recommendations are made for the development of tools to support online computer-supported collaborative work in design using a shared virtual environment

    The interaction of lean and building information modeling in construction

    Lean construction and Building Information Modeling are quite different initiatives, but both are having profound impacts on the construction industry. A rigorous analysis of the myriad specific interactions between them indicates that a synergy exists which, if properly understood in theoretical terms, can be exploited to improve construction processes beyond the degree to which it might be improved by application of either of these paradigms independently. Using a matrix that juxtaposes BIM functionalities with prescriptive lean construction principles, fifty-six interactions have been identified, all but four of which represent constructive interaction. Although evidence for the majority of these has been found, the matrix is not considered complete, but rather a framework for research to explore the degree of validity of the interactions. Construction executives, managers, designers and developers of IT systems for construction can also benefit from the framework as an aid to recognizing the potential synergies when planning their lean and BIM adoption strategies

    Smart Photos

    Recent technological leaps have been a great catalyst for changing how people interact with the world around us. Specifically, the field of Augmented Reality has led to many software and hardware advances that have formed a digital intermediary between humans and their environment. As of now, Augmented Reality is available to the select few with the means of obtaining Google Glass, Oculus Rifts, and other relatively expensive platforms. Be that as it may, the tech industry\u27s current goal has been integration of this technology into the public\u27s smartphones and everyday devices. One inhibitor of this goal is the difficulty of finding an Augmented Reality application whose usage could satisfy an everyday need or attraction. Augmented reality presents our world in a unique perspective that can be found nowhere else in the natural world. However, visual impact is weak without substance or meaning. The best technology is invisible, and what makes a good product is its ability to fill a void in a person\u27s life. The most important researchers in this field are those who have been augmenting the tasks that most would consider mundane, such as overlaying nutritional information directly onto a meal [4]. In the same vein, we hope to incorporate Augmented Reality into everyday life by unlocking the full potential of a technology often believed to have already have reached its peak. The humble photograph, a classic invention and unwavering enhancement to the human experience, captures moments in space and time and compresses them into a single permanent state. These two-dimensional assortments of pixels give us a physical representation of the memories we form in specific periods of our lives. We believe this representation can be further enhanced in what we like to call a Smart Photo. The idea behind a Smart Photo is to unlock the full potential in the way that people can interact with photographs. This same notion is explored in the field of Virtual Reality with inventions such as 3D movies, which provide a special appeal that ordinary 2D films cannot. The 3D technology places the viewer inside the film\u27s environment. We intend to marry this seemingly mutually exclusive dichotomy by processing 2D photos alongside their 3D counterparts

    Global Teamwork: A Study of Design Learning in Collaborative Virtual Environments

    Get PDF
    With the recent developments in communication and information technologies, using Collaborative Virtual Environments (CVEs) in design activity has experienced a remarkable increase. In this paper we present a collaborative learning activity between the University of Sydney (USYD), and the Istanbul Technical University (ITU). This paper shares our teaching experience and discusses the principles of collaborative design learning in virtual environments. Followed by a study on students’ perception on the courses and collaborative learning in both universities, this paper also suggests future refinements on the course structure and the main areas of collaborative design learning.
