Abstract: Systems, devices, methods and computer-readable storage mediums storing instructions are provided that enable multi-user interaction with detailed virtual objects of a shared virtual space superimposed for all users identically on a shared physical space. Experiences that can be achieved by users of a multi-user group during such interaction are collectively called a multi-user virtual reality interaction environment experience. During the enabled interaction, users can collaborate and communicate simultaneously within the shared virtual space and the shared physical space. This results in both spaces being interrelated and intuitive to navigate and creates a virtual reality experience combined with physical reality, which is shared by all users.
