WIPO Patent Application WO/2020/031949

Kind Code:

A1

Abstract:

The present invention appropriately evaluates a risk when a subject moves. This information processing device is provided with a head information acquisition unit, a display control unit, a viewpoint information acquisition unit, and a risk assessment unit. The head information acquisition unit acquires head information specifying the movement of a head of a subject. The display control unit causes an image display device to display a simulative moving image simulatively representing the field of view of a person that moves on a course. The simulative moving image includes a scene including a target, and changes according to the movement of the head of the subject specified by the head information. The viewpoint information acquisition unit acquires viewpoint information specifying the position of a viewpoint of the subject on the simulative moving image while the simulative moving image is being displayed. The risk assessment unit assesses a risk on the basis of the degree of a match between the position of the viewpoint of the subject specified by the viewpoint information and the position of the target at a timing when the scene including the target within the simulative moving image is displayed, and outputs assessment information indicating the result of the assessment of the risk.
