Information displaying system and information displaying device

An information displaying device comprising:

• a memory storing a program;
• a display device;
• and
• a processor configured to execute the program to implement a process including:
• displaying a time axis region on the display device, the time axis region being configured to display a first time axis of a biosignal along a first direction to display a second time axis of the biosignal along the first direction, and to display a first mark on the first time axis in the time axis region, the first time axis representing an entire period of time when the biosignal was measured, and the first mark being a pointer mark indicating a time point designated by a user;
• displaying a signal display region on the display device, the signal display region being configured to display a plurality of waveforms of the biosignal side by side in a second direction which is different from the first direction, the second time axis displayed on the time axis region representing a period of time when the waveforms displayed on the signal display region were obtained;
• in response to receiving, from the user, an operation of designating a specific time point on the signal display region, displaying the first mark at a location on the first time axis in the time axis region corresponding to the specific time point on the signal display region;
• and
• in response to receiving an operation of designating a section on the first time axis in the time axis region from the user,
• displaying, in the signal display region, the plurality of waveforms for a time range corresponding to the designated section on the first time axis, and
• in a case in which the first mark displayed on the first time axis is located within the designated section on the first time axis, displaying, in the signal display region, a line crossing the plurality of waveforms in the second direction at the time point indicated by the first mark.

A non-transitory computer-readable recording medium storing a computer program to cause a processor in an information displaying device including a display device to execute a method, the method comprising:

• displaying a time axis region on the display device, the time axis region being configured to display a first time axis of a biosignal along a first direction, to display a second time axis of the biosignal along the first direction, and to display a first mark on the time axis in the time axis region, the first time axis representing an entire period of time when the biosignal was measured, and the first mark being a pointer mark indicating a time point designated by a user;
• displaying a signal display region on the display device, the signal display region being configured to display a plurality of waveforms of the biosignal side by side in a second direction which is different from the first direction, the second time axis displayed on the time axis region representing a period of time when the waveforms displayed on the signal display region were obtained;
• in response to receiving, from the user, an operation of designating a specific time point on the signal display region, displaying the first mark at a location on the first time axis in the time axis region corresponding to the specific time point on the signal display region, and
• in response to receiving an operation of designating a section on the first time axis in the time axis region from the user,
• displaying, in the signal display region, the plurality of waveforms for a time range corresponding to the designated section on the first time axis, and
• in a case in which the first mark displayed on the first time axis is located within the designated section on the first time axis, displaying, in the signal display region, a line crossing the plurality of waveforms in the second direction at the time point indicated by the first mark.
