summary |
This paper describes the results of a study evaluating the effects of computer mediation on collaboratively solving architectural design problems. Pairs of graduate design students were asked to work on a landscape architecture design problem via computer terminals. In one condition they were allowed to communicate with an electronic whiteboard and a chat-line while in the other, the chat-line was substituted with video-conferencing (real-time video and audio). The protocols were evaluated according to two models. First, they were coded according to the pattern of collaboration, distinguishing meta-planning, negotiation, evaluation, and individual work. No differences were found between the two groups when coded this way. The protocols were also coded in terms of the problem-solving content, distinguishing task-related exchanges, interface-related exchanges, low-level design exchanges, and high-level design exchanges. The results showed that in the bandwidth-limited chat-line condition, participants cut down task and interface-related as well as low-level design exchanges but attempted to maintain the same amount of high-level design exchanges. When the final designs were evaluated by professional architects, no differences were found between two conditions indicating that chat-line participants implicitly compensate for the narrower bandwidth interface. |
