Display, display method, and display program

A display method used in a display device for visually displaying, on a display screen, positional relationships between a plurality of target objects, the display method comprising:

• an acquisition step of acquiring position information pieces each of which indicates a position of a corresponding one of the target objects;
• a categorization step of categorizing the target objects into a plurality of groups in accordance with the acquired position information pieces;
• a calculation step of calculating an inter-group positional relationship by using the acquired position information pieces, the inter-group positional relationship indicating a positional relationship between the groups;
• a determination step of determining one or more partitions by which the display screen is partitioned into a plurality of areas, each partition being tilted with respect to a reference axis in accordance with the calculated inter-group positional relationship, the reference axis being parallel to one of edges of the display screen;
• and
• a display step of displaying, in each of the areas partitioned by the one or more partitions on the display screen, a positional relationship between the target objects belonging to a corresponding one of the groups.

A display program used in a display device for visually displaying, on a display screen, positional relationships between a plurality of target objects, the display program comprising:

• an acquisition step of acquiring position information pieces each of which indicates a position of a corresponding one of the target objects;
• a categorization step of categorizing the target objects into a plurality of groups in accordance with the acquired position information pieces;
• a calculation step of calculating an inter-group positional relationship by using the acquired position information pieces, the inter-group positional relationship indicating a positional relationship between the groups;
• a determination step of determining one or more partitions by which the display screen is partitioned into a plurality of areas, each partition being tilted with respect to a reference axis in accordance with the calculated inter-group positional relationship, the reference axis being parallel to one of edges of the display screen;
• and
• a display step of displaying, in each of the areas partitioned by the one or more partitions on the display screen, a positional relationship between the target objects belonging to a corresponding one of the groups.

A display device for visually displaying, on a display screen, positional relationships between a plurality of target objects, the display device comprising:

• an acquisition unit operable to acquire (i) position information pieces each of which indicates a position of a corresponding one of the target objects, and (ii) direction information pieces each of which indicates a direction that the corresponding target object is facing;
• a calculation target position acquisition unit operable to acquire calculation target positions whose attention levels are to be respectively calculated, each attention level indicating to what extent a corresponding one of the calculation target positions is attracting attention from the target objects;
• an attention level calculation unit operable to calculate the attention level of each calculation target position in accordance with (i) the positions indicated by the position information pieces and (ii) the directions indicated by the direction information pieces;
• and
• a display unit operable to display, on the display screen, (i) the positional relationships between the target objects and (ii) the calculation target positions in such a manner that the calculation target positions are highlighted according to the attention levels thereof.
