Studies of shared virtual environments (SVEs) have used widely different approaches to how copresence and interaction should be analyzed. In this paper, I argue that-if we take our starting point from what people actually do in shared VE's, and findings about what they do together-then we can focus much more narrowly on the few essential features of(More)
In this paper we present the results of a trial in which two participants collaborated on a puzzle-solving task in networked virtual environments. The task was a Rubik's cube type puzzle, and this meant that the two participants had to interact with the space and with each other very intensivelyFand they did this successfully despite the limitation of the(More)
The realism of avatars in terms of behavioral and form is critical to the development of collaborative virtual environments. In the study we utilized state of the art, real-time face tracking technology to track and render facial expressions unobtrusively in a desktop CVE. Participants in dyads interacted with each other via either a videoconference (high(More)
Has the Internet affected the ways in which people communicate by lessening the effects of distance and affecting how people interact? To examine this question, we study scholarly and interpersonal relationships – communicating in person and by email – in two scholarly networks, one in a large university and one dispersed across North America. Not only are(More)
This paper examines various aspects of "openness" in research, and seeks to gauge the degree to which escience is congruent with "open science." Norms and practices of openness, arguably, have been vital for the work of modern scientific communities, but concerns about the growth of stronger technical and institutional restraints on access to research(More)
Sweden, following the lead of other countries, has recently embarked on an ambitious e-Science programme. This paper focuses on one central aspect of this programme; data sharing. The reason for this focus is twofold: one reason is that data sharing has become one of the most powerful and promising directions in e-Science in general, even if also laden with(More)
In this chapter, I will give an overview of some central issues in research on shared virtual environments (VEs) – including " presence " , " copresence " , communication, and small and large group dynamics-across a range of virtual reality (VR) technologies and different conditions under which they are used. I will discuss different studies of the(More)
This paper describes two methods for analyzing interactions in collaborative virtual environments (CVEs): one whereby quantitative data are captured, interaction is categorized into a number of activities, and statistical analysis can be performed on frequencies and sequences of events. The other is based on the transcription of individual fragments of(More)
