Information processing system, information processing method, medium, and management device

An information processing method performed by a system including a presentation device, a management device, and a communication device, comprising:

• causing the presentation device to change identifiers periodically so as to present an identifier;
• causing the presentation device and the management device to share the identifier presented on the presentation device with each other;
• causing the communication device to acquire the identifier presented on the presentation device when an identifier acquisition operation by a user is detected, and to transmit, to the management device, (i) related information of the acquired identifier and (ii) an operation instruction to operate an information acquisition device identified by the acquired identifier;
• and
• causing the management device to identify the information acquisition device based on the related information of the identifier received from the communication device, and to operate the identified information acquisition device based on the operation instruction received from the communication device.

A non-transitory computer-readable recording medium with a program stored therein, the program causing a computer of a management device connected to a presentation device and a communication device to execute:

• sharing an identifier periodically changed by and presented on the presentation device;
• receiving, from the communication device that acquires the identifier presented on the presentation device, (i) related information of the acquired identifier and (ii) an operation instruction to operate an information acquisition device identified by the acquired identifier;
• identifying the information acquisition device based on the related information of the identifier received from the communication device;
• and
• operating the identified information acquisition device based on the operation instruction received from the communication device.

A management device connected to a presentation device and a communication device, and comprising a processor, the processor of the management device executing:

• sharing an identifier periodically changed by and presented on the presentation device;
• receiving, from the communication device that acquires the identifier presented on the presentation device, (i) related information of the acquired identifier and (ii) an operation instruction to operate an information acquisition device identified by the acquired identifier;
• identifying the information acquisition device based on the related information of the identifier received from the communication device;
• and
• operating the identified information acquisition device based on the operation instruction received from the communication device.
