An information processing method by a controller of an information processing apparatus, comprising:
- receiving, by the controller via a communication interface, screen information regarding measurement information on a physical quantity from one or more waveform analyzers that acquire the measurement information;
- transmitting, by the controller via the communication interface, the acquired screen information to a plurality of operation terminals;
- receiving, from a first operation terminal of the plurality of operation terminals, a request for operation on the one or more waveform analyzers through the screen information;
- determining, by the controller, whether a control right to operate the one or more waveform analyzers is granted to any operation terminal of the plurality of operation terminals except the first operation terminal;
- and
- granting, by the controller, the control right to the first operation terminal in response to determining that the control right is not granted to any operation terminal of the plurality of operation terminals except the first operation terminal.
