Patent number: 11334151Abstract: An estimator (111) estimates whether an object is on the line of sight of the user. When a first object is estimated as being on the line of sight of the user continuously for a first threshold time, set for the user, or longer, a displayer (112) displays a second object in the field of view of the user. The second object expresses information about the first object.
