Heat map presentation device and heat map presentation program

A heat map presentation device comprising:

• a visual observation region information acquisition unit that acquires visual observation region information obtained as a result of detecting a region that a viewer is viewing in a three-dimensional image displayed on a virtual three-dimensional space of a head-mounted display;
• a creation factor detection unit that detects a number of viewing times by the viewer and viewing time by the viewer as a plurality of creation factors for a heat map for each of a plurality of regions obtained by dividing the three-dimensional image on the basis of the visual observation region information;
• a heat map creation unit that creates the heat map that is displayed on the three-dimensional space of the head-mounted display on the basis of the plurality of creation factors detected by the creation factor detection unit;
• and
• a heat map display control unit that displays the heat map created by the heat map creation unit on the three-dimensional space of the head-mounted display,
• wherein the heat map creation unit determines a display mode on a plane of the heat map on the basis of one of the plurality of creation factors or a combination of the plurality of creation factors, determines the display mode on a depth of the heat map on the basis of a remaining creation factor among the plurality of creation factors, and creates the heat map on the basis of a determination content.
