Despite the proliferation of platforms for social Virtual Reality (VR) communicating emotional expression via an avatar remains a significant design challenge. In order to better understand the design space for expressive Nonverbal Communication (NVC) in social VR we undertook an inventory of the ten most prominent social VR platforms. Our inventory identifies the dominant design strategies for movement, facial control, and gesture in commercial VR applications, and identifies opportunities and challenges for future design and research into social expression in VR. Specifically, we highlight the paucity of interaction paradigms for facial expression and the near nonexistence of meaningful control over ambient aspects of nonverbal communication such as posture, pose, and social status.
