Analyzing the use of VoIP technology in collaborative modeling

Collaborative editing systems often use communication channels in order to make the collaboration more effective. In this work, we present a case study of pair communication using audio via VoIP (Voice over Internet Protocol) technology during collaborative modeling sessions. The study provides an analysis of audio and textual chat as communication medium and presents data on usage patterns, user interaction and attitudes when using collaborative editing systems. The qualitative and quantitative analysis suggests that VoIP technology does have advantages over textual chat in collaborative modeling when used for communication.
