This thesis presents a series of pilot studies and experiments which explore the effectiveness of different human-to-human communication media in supporting synchronous computer-based shared workspace interaction between small groups of people working on cooperative tasks. Four important factors of synchronous shared workspace, communication medium, group size, and group task are examined in these studies.
Two pilot studies have been carried out to evaluate a shared workspace conferencing software, supplemented by face-to-face, audio-based, and text-based communication media, in providing the shared workspace for groups of two people working on a range of different cooperative tasks. The results of these studies along with the findings of other research are then used to define the scope of the substantive experiments of the thesis.
The first major experiment studies the relative impact of face-to-face, full-motion video, slow-motion video, and audio-only communication media when they are used in conjunction with shared workspace software to support dyadic group problem-solving tasks. The study measures (i) the subjects’ satisfaction and ranking of the work environments using a number of questionnaires, (ii) the style of the conversation patterns between the subjects, and (iii) the groups generated solutions to the problems. The results of the experiment indicate that although the subjects rate face-to-face communication to be slightly more “natural” than the others, there are no differences between the outputs of the groups, or the style of the groups’ communication patterns under different communication settings.
The second experiment examines the relative effectiveness of face-to-face, and audio-only communication media in supporting conferencing software to provide a shared workspace environment for groups of three people working on cooperative problem-solving tasks. The study also examines the effects of changing the group size from two to three under similar experimental conditions. The three measures of the previous experiment are also used in this study. The results show that there is very little difference between the subjects’ satisfaction of the two environments, and no difference between the environments in terms of the groups’ outputs, or the style of the groups’ conversation patterns in each of the settings.
The results of the experiments of the thesis have been used to draw a number of conclusions which are important for improving the design of synchronous computer-based shared workspaces to provide more effective means of supporting group work and group communication between physically remote collaborators. In particular, it is suggested that in this type of interaction, audio communication is very important, but that the further addition of video communication in any form is of no perceptible benefit.
The thesis also presents a critical review of previous research on human-to-human communication and group work in both computer-based, and non-computer-based work environments. Directions for future research are also discussed.
