Previous studies have demonstrated the importance of providing users with a coherent environment across distant sites. To date, it remains unclear how such an environment affects people's gestures and their comprehension. In this study, we investigate how a coherent environment across distant sites affects people's hand gestures when collaborating on physical tasks. We present video-mediated technology that provides distant users with a coherent environment in which they can freely gesture

Using this system, we examine the values of a coherent environment by comparing remote collaboration on physical tasks in a fractured setting versus a coherent setting. The results indicate that a coherent environment facilitates gesturing toward remote objects and their use improves task performance. The results further suggest that a coherent environment improves the sense of copresence across distant sites and enables quick recovery from misunderstandings.
