Communication and social interaction are vast subjects that extend well outside of the scope of this book. Furthermore, social interaction in VR, or social VR, remains in a stage of infancy, with substantial experimentation and rethinking of paradigms occurring. Nevertheless, connecting humans together is one of the greatest potentials for VR technology. Although it might seem isolating to put displays between ourselves and the world around us, we can also be brought closer together through successful interaction mechanisms. This section highlights several interesting issues with regard to social interaction, rather than provide a complete review.
