Information processing device, and display method

A display method performed by an information processing device that makes a display device display information, the display method comprising:

• acquiring position information indicating a position of each of a plurality of aircraft, reference direction information indicating a reference direction for viewing the plurality of aircraft in a three-dimensional space on the display device, direction information indicating one or more directions different from the reference direction for viewing the plurality of aircraft in the three-dimensional space on the display device, course information indicating a course of each of the plurality of aircraft, and speed information indicating speed of each of the plurality of aircraft and generating the plurality of aircraft as viewed from the reference direction in the three-dimensional space based on the position information and the reference direction information;
• evaluating an average value of an overlap level between the plurality of the aircraft as viewed from the reference direction in a first predetermined period based on the course information and the speed information as a first average overlap level and evaluating an average value of the overlap level between the plurality of aircraft as viewed from each of the one or more directions different from the reference direction in the first predetermined period based on the direction information, the course information and the speed information as second average overlap levels;
• detecting a direction in a case where the average overlap level is lowest among the first average overlap level as viewed from the reference direction and the second average overlap levels as viewed from the one or more directions different from the reference direction;
• and
• executing control so that the plurality of aircraft as viewed from the detected direction are displayed by the display device.

An information processing device that makes a display device display information, the information processing device comprising:

• a processor to execute a program;
• and
• a memory to store the program which, when executed by the processor, performs processes of,
• acquiring position information indicating a position of each of a plurality of aircraft, reference direction information indicating a reference direction for viewing the plurality of aircraft in a three-dimensional space on the display device, direction information indicating one or more directions different from the reference direction for viewing the plurality of aircraft in the three-dimensional space on the display device, course information indicating a course of each of the plurality of aircraft, and speed information indicating speed of each of the plurality of aircraft and generating the plurality of aircraft as viewed from the reference direction in the three-dimensional space based on the position information and the reference direction information,
• evaluating an average value of an overlap level between the plurality of aircraft as viewed from the reference direction in a first predetermined period based on the course information and the speed information as a first average overlap level and evaluating an average value of the overlap level between the plurality of the aircraft as viewed from each of the one or more directions different from the reference direction in the first predetermined period based on the direction information, the course information and the speed information as second average overlap levels,
• detecting a direction in a case where the average overlap level is lowest among the first average overlap level as viewed from the reference direction and the second average overlap levels as viewed from the one or more directions different from the reference direction, and
• executing control so that the plurality of aircraft as viewed from the detected direction are displayed by the display device.
