A road map on human-human interaction and fine-function collaboration in collaborative integrated design environments

From human-computer interaction to human-human interaction and from information sharing to function collaborative are major advances from traditional single-user design to collaborative design. This work presents a road map to achieve this goal with computer-aided tools. The models, methods and techniques in developing collaborative tools for collaborative integrated design environment are discussed in details. The proposed ideas have been implemented in an aware collaborative tool to support transparent CAx/DFx systems.
