The authors present an analysis of communication behavior in face-to-face collaboration using a multi-user augmented reality (AR) interface. 2 experiments were conducted. In the 1st experiment, collaboration with AR technology was compared with more traditional unmediated and screen-based collaboration. In the 2nd experiment, the authors compared collaboration with 3 different AR displays. Several measures were used to analyze communication behavior, and the authors found that users exhibited many of the same behaviors in a collaborative AR interface as in face-to-face unmediated collaboration. However, user communication behavior changed with the type of AR display used. The authors describe implications of these results for the design of collaborative AR interfaces and directions for future research.
