Literature review

There are many studies that reveal the nature of design thinking and the nature of conceptual design as distinct from detailed or embodiment design. The results can assist in our understanding of how the process of design can be supported and how new technologies can be introduced into the workplace. Existing studies provide limited information about the nature of collaborative design as it takes place on the ground and in the actual working context. How to provide appropriate and effective of support for collaborative design information sharing across companies, countries and heterogeneous computer systems is a key issue. As data are passed between designers and the computer systems they employ, many exchanges are made. These exchanges may be used to establish measures of the benefits that new support systems can bring. Collaboration support tools represent a fast growing section of the commercial software market place and a reasonable range of products are available. Many of them offer significant application to design for the support of distributed meetings by the provision of video and audio communications and the sharing of information, including collaborative sketching. The tools that specifically support 3D models and other very design specific features are less common and many of those are in prototype stages of development. A key question is to find viable ways of combining design information visualisation support with the collaboration support technologies that can be seen today. When collaborating, different views will need to be accessible at different times to all the collaborators. The architects may want to explain some ideas on their model, the structural engineers on their model and so on. However, there are issues of ownership when the structural engineer wants to manipulate the architect’s model and vice versa. The modes of working, synchronous or asynchronous may have a bearing as in a synchronous session there is control of what is happening

I am here - are you there? Sense of presence and implications for virtual world design

We use the language of presence and place when we interact online: in our instant text messaging windows we often post: Are you there? Research indicates the importance of the sense of presence for computer-supported collaborative virtual learning. To realize the potential of virtual worlds such as Second Life, which may have advantages over conventional text-based environments, we need an understanding of design and the emergence of the sense of presence. A construct was created for the sense of presence, as a collaborative, action-based process (Spagnolli, Varotto, & Mantovani, 2003) with four dimensions (sense of place, social presence, individual agency, and mediated collaborative actions). Nine design principles were mapped against the four dimensions. The guiding question for the study\u27s exploration of the sense of presence was: In the virtual world Second Life, what is the effect on the sense of presence in collaborative learning spaces designed according to the sense of presence construct proposed, using two of the nine design principles, wayfinding and annotation? Another question of interest was: What are the relationships, if any, among the four dimensions of presence? The research utilized both quantitative and qualitative measures. Twenty learners recruited from the Graduate School of Education and Psychology at Pepperdine University carried out three assigned collaborative activities in Second Life under design conditions foregrounding each of the two design conditions, and a combination of the two. Analyses from surveys, Second Life interactions, interviews and a focus group were conducted to investigate how various designed learning environments based in the virtual world contributed to the sense of presence, and to learners\u27 ability to carry out collaborative learning. The major research findings were: (a) the construct appears robust, and future research in its application to other virtual worlds may be fruitful; (b) the experience of wayfinding (finding a path through a virtual space) resulted overall in an observed pattern of a slightly stronger sense of place; (c) the experience of annotation (building) resulted overall in an observed pattern of a slightly stronger sense of agency; and (d) there is a positive association between sense of place and sense of agency
