Survey of collaborative drawing support tools
Along with recent experiments in the design of communication or computer tools for supporting various kinds of group working, the development of collaborative drawing systems has emerged as a notable research area within the field of Computer-Supported Cooperative Work. This paper reports a survey of the experiments in collaborative drawing support tools with an objective of reviewing how the issues of supporting collaborative design have been addressed by the research prototypes. The survey is presented in three parts: (1) findings from the observations of group interaction in drawing and design activities, (2) a framework for classifying the design issues experimented with by prototypes developers, and (3) a categorisation of the current prototype systems by interrelating the patterns of group use observed with the system features classified. The survey indicates that there are currently at least three different strategies of developing collaborative drawing support tools, which reflect the existence of diversified understanding and technological responses to what and how human collaboration in design may be supported.
