OpenMic: Utilizing Proxemic Metaphors for Conversational Floor Transitions in Multiparty Video Meetings

Turn-taking is one of the biggest interactivity challenges in multiparty remote meetings. One contributing factor is that current videoconferencing tools lack support for proxemic cues; i.e., spatial cues that humans use to enact their social relations and intentions. While more recent tools provide support for proxemic metaphors, they often focus on approach and leave-taking rather than turn-taking. In this paper, we present OpenMic, a videoconferencing system that utilizes proxemic metaphors for conversational floor management by providing 1) a Virtual Floor that serves as a fixed-feature space for users to be aware of others’ intention to talk, and 2) Malleable Mirrors, which are video and screen feeds that can be continuously moved and resized for conversational floor transitions. Our exploratory user study found that these system features can aid the conversational flow in multiparty video meetings. With this work, we show potential for embedding proxemic metaphors to support conversational floor management in videoconferencing systems.
