1. A portable information device, comprising:
a display;
a communication interface provided for connection to a network;
a storage device;
at least one of a camera and a range sensor; and
a processor configured to:
acquire, from a relay apparatus that is installed in a space where the portable information device is present and that connects the portable information device to the network, relay apparatus identification information which is information identifying the relay apparatus;
determine whether spatial configuration information obtained by mapping the space, which is necessary for displaying on the display, is registered in the storage device;
in a case that the spatial configuration information is not registered, send a request to transmit the spatial configuration information, from the communication interface to a server connected to the network through the relay apparatus;
in a case that the spatial configuration information is received from the server in response to the request, store the spatial configuration information in the storage device in association with the relay apparatus identification information; and
in a case that the spatial configuration information is not received from the server in response to the request:
use the at least one of the camera and the range sensor to generate the spatial configuration information on the space; and
store the spatial configuration information that has been generated in the storage device in association with the relay apparatus identification information.
