Conference paper (peer-reviewed)abstract
- Under which conditions has collaboration added value over individual work? How does performance change when using different technologies? These are important questions for industry and for research. This paper addresses them for pairs versus individuals using physical objects and virtual representations for object-focused task-solving. Based upon previous research on pair’s performance and experiences for collaboration in a real setting and four different distributed virtual environments (VEs), single-user experimental studies were carried out. The results show that in relation to performance, pairs working in networked CAVE™ technologies are superior compared to individuals, or pairs working in other distributed settings. In general, social interaction works as a facilitator for this type of task solving in networked VEs. Though, best performance was found in the real setting, with no major difference when comparing individuals versus pairs, working in VEs often were appreciated higher than working with physical objects.

Immersiveness and Symmetry in Copresent Scenarios
- 2005
-
In: Proceeding of IEEE VR2005. ; , s. 171-178
-
Conference paper (peer-reviewed)abstract
- Collaboration at a distance has long been a research goal of distributed virtual environments. A number of recent technologies, including immersive projection technology systems (IPTs) and head-mounted displays (HMDs), promise a new generation of technologies that are more intuitive to use than desktop-based systems. This paper presents an experiment that compares collaboration in five different settings. Pairs collaborated on the same puzzle-solving task using one of: an IPT connected to another IPT, an IPT connected to an HMD, an IPT connected to a desktop system, two connected desktop systems, or face-to-face collaboration with real objects. The findings demonstrate the benefits of using immersive technologies, and show the advantages of using symmetrical settings for better performance. Some usability problems of the different distributed settings are addressed, as well as factors such as “presence” and “copresence” and how these contribute to the participants’ overall experiences

Simulation and serious games for firefighter training : challenges for effective use

Journal article (peer-reviewed)abstract
- One of the main criteria of effectively managing emergency and crisis situations is good preparedness. Simulation and serious games (SSG) are often advocated as promising technologies supporting training and increasing the skills necessary to deal with new, complex and often unexpected situations. This paper is based on an investigation of why a seemingly appropriate SSG technology was not used long after procurement. We identified potential obstacles and challenges of SSG implementation in organizations responsible for societal safety. The focus is on fire fighter training and is based on 33 interviews with major stakeholders from seven countries, from organizations with successful as well as unsuccessful experiences of SSG use. By contrasting the different incentives and views regarding the technology use, this paper contributes to a better understanding of challenges related to SSG implementation and use. The results confirm the possible benefits of SSGs, but also highlight an urgent need for new approaches to integrate these new technologies into organizational practices. Only by formulating local, organizational strategies with the SSG use can the technology be implemented successfully
