Video conferencing commonly employs a video portal met-aphor to connect individuals from remote spaces. In this work, we explore an alternate metaphor, a shared depth-mirror, where video images of two spaces are fused into a single shared, depth-corrected video space. We realize this metaphor in OneSpace, where the space respects virtual spatial relationships between people and objects as if all parties were looking at a mirror together. We report prelim-inary observations of OneSpace's use, noting that it encour-ages cross-site, full-body interactions, and that participants employed the depth cues in their interactions. Based on these observations, we argue that the depth mirror offers new opportunities for shared video interaction in the form of a shared stage.
