Sansar is a social virtual reality platform developed by the San Francisco-based firm Linden Lab, and now owned by San Francisco-based firm Wookey Project Corp. It launched in “creator beta” to the general public on July 31, 2017. The platform enables user-created 3D spaces where people can create and share interactive social experiences, such as playing games, watching videos, and having conversations in VR. Each participant is represented by a detailed avatar that is the graphical representation of the user including speech-driven facial animations and motion-driven body animations.
