Communication Behaviors in Colocated Collaborative AR Interfaces

We present an analysis of communication behavior in face-to-face collaboration using a multi-user Augmented Reality (AR) interface. We conducted two experiments. In the first, collaboration with AR technology was compared to more traditional unmediated and screen-based collaboration. In the second we compare collaboration with three different AR displays. Several measures are used to analyze communication behavior, and we found that users exhibited many of the same behaviors in a collaborative AR interface as in face-to-face unmediated collaboration. User communication behavior also changed with the type of AR display used. We describe implications of these results for the design of collaborative AR interfaces and directions for future research.
