1. A head-mounted display apparatus comprising:
a display unit that transmits an outside scene including a first target object and a second target object;
a line-of-sight detection unit that detects a line-of-sight direction of a user;
a time calculation unit that calculates a first time and second time, the first time being a time that the first target object requires to reach the user, and the second time being a time that the second target object requires to reach the user; and
a determination unit that acquires a first information about the first target object and a second information about the second target object, that calculates a risk level of the first target object based on the first information and the first time, and that calculates a risk level of the second target object based on the second information and the second time, wherein
the display unit displays a first image related to the first target object when an attention level for the first target object based on the line-of-sight direction and the risk level of the first target object is higher than an attention level for the second target object based on the line-of-sight direction and the risk level of the second target object.
