1. A head-mounted display apparatus comprising:
at least one camera;
at least one sensor; and
at least one processor operatively connected to the at least one camera and the at least one sensor,
wherein the at least one processor is configured to:
acquire information about head pose and head-based gaze direction of a user, based on data input from the at least one sensor and multiple key points input from the at least one camera according to recognizing rotation of a user's head,
estimate gaze lines of the user, based on the acquired information about head pose and head-based gaze direction, and
estimate a distance to a target point, based on the gaze lines of the user, according to identifying that vestibulo-ocular reflex is activated based on the gaze lines of the user.
