Information processing system, information processing terminal device, server device, information processing method and program thereof

A server apparatus, comprising:

• a processor configured to communicate with an information processing terminal configured to acquire spatial information representing a real space and display an image representing a mixed reality space obtained by superimposing a virtual space in the real space;
• and
• a memory connected to the processor,
• the memory including a storage unit configured to, for each of a plurality of real spaces, store mixed space management information in which information for identifying the real space, anchor information for defining a superimposition position of the virtual space in the real space, and anchor information corresponding to an adjacent real space are associated, and
• the processor being configured to, in a case where an acquisition request for anchor information corresponding to a first real space among the plurality of real spaces is received from the information processing terminal, transmit response information including first anchor information corresponding to the first real space and second anchor information corresponding to a second real space adjacent to the first real space to the information processing terminal of a request source based on mixed space management information corresponding to the first real space.

An information processing method comprising, at an information processing system including an information processing terminal configured to acquire spatial information representing a real space and display an image representing a mixed reality space obtained by superimposing a virtual space in the real space, and a server apparatus configured to communicate with the information processing terminal:

• at the server apparatus, for each of a plurality of real spaces, creating and managing mixed space management information in which information for identifying the real space, anchor information for defining a superimposition position of the virtual space in the real space, and anchor information corresponding to an adjacent real space are associated,
• at the server apparatus, in a case where an acquisition request for anchor information corresponding to a first real space among the plurality of real spaces is received from the information processing terminal, transmitting response information including first anchor information corresponding to the first real space and second anchor information corresponding to a second real space adjacent to the first real space to the information processing terminal of a request source based on mixed space management information corresponding to the first real space,
• at the information processing terminal, in a case where the information processing terminal is placed into the first real space among the plurality of real spaces, acquiring the response information from the server apparatus by transmitting the acquisition request for the anchor information to the server apparatus, and
• at the information processing terminal, storing the acquired response information in a storage medium and, in a case where the information processing terminal is placed into the second real space, generating information representing a mixed reality space obtained by superimposing the virtual space in the second real space based on the second anchor information included in the response information stored in the storage medium.
