Processing device, processing system, processing method, and storage medium

A processing method, comprising:

• acquiring a reception result obtained by a receiver receiving at least a portion of signals emitted from a plurality of transmitters;
• determining, based on strengths of the signals, a position of the transmitter at which the receiver is present;
• referring to transitionable data when the receiver transitions from a first position of one of the plurality of transmitters to a second position of another of the plurality of transmitters, the transitionable data being of transitionable positions from positions of the plurality of transmitters;
• approving the transition in a first case in which the transition is determined to be possible based on the transitionable data;
• and
• not approving the transition during a first period in a second case in which the transition is determined to be impossible based on the transitionable data.

A non-transitory computer-readable storage medium configured to store a program,

• the program, when executed by a computer, causing the computer to:
• acquire a reception result obtained by a receiver receiving at least a portion of signals emitted from a plurality of transmitters;
• determine, based on strengths of the signals, a position of the transmitter at which the receiver is present;
• refer to transitionable data when the receiver transitions from a first position of one of the plurality of transmitters to a second position of another of the plurality of transmitters, the transitionable data being of transitionable positions from positions of the plurality of transmitters;
• approve the transition in a first case in which the transition is determined to be possible based on the transitionable data;
• and
• not approve the transition during a first period in a second case in which the transition is determined to be impossible based on the transitionable data.
