A technology for reducing a processing delay when a plurality of mixed reality spaces are shared between terminals is provided.
An information processing system includes a terminal configured to display an image representing a mixed reality space obtained by superimposing a virtual space in a real space, and a server apparatus configured to communicate with the terminal. The server apparatus manages, for each of a plurality of real spaces, information for identifying the real space and anchor information for defining a superimposition position of the virtual space in the real space and, in a case where an acquisition request for anchor information corresponding to a first real space is received from the terminal, transmits response information including anchor information corresponding to the first real space and anchor information corresponding to a second real space adjacent to the first real space to the terminal. The terminal stores the response information received from the server apparatus and, in a case where the terminal is placed into the second real space, displays an image representing a mixed reality space based on anchor information corresponding to the second real space.
