Abstract

A high-presence videoconferencing system called "Being Here System (BHS)" has been proposed and implemented. The system superimposes the remote person's extracted figure on the local site front view in the display. Though a user study by questionnaire was conducted, the user's actual behavior was left out. Thus in this paper, the influence on user's communication behavior is investigated. The analysis of the recorded video of the study revealed that the system affected user's communication behavior such as turn taking, speech time, speech overlapping, and gaze. The result suggests that considering the local site front view as a background of the remote person is one practical way to create the same-room illusion, which facilitates communication.
