Claim 0:
1. A method of providing content with an advertisement disclosure in an apparatus including an interface unit, a gaze detection unit, and a control unit, the method comprising:
detecting, by the control unit, an advertisement object located within a user sight from the content that is displayed in the interface unit in a three-dimensional space by a visual interface;
inserting, by the control unit, the advertisement disclosure for advertisement identification in an adjacent position to the advertisement object; and
controlling, by the control unit, a position or direction of the advertisement disclosure based on a user gaze upon detecting the user gaze by the gaze detection unit,
wherein the controlling comprises:
generating, in a three-dimensional space, a triangle using an origin, user coordinates, and advertisement disclosure coordinates obtained by the inserting of the advertisement disclosure;
generating orthogonal projections for the triangle on an x-y plane, a y-z plane and a z-x plane, respectively;
calculating a direction of rotation and an angle of rotation of the advertisement disclosure for each of the orthogonal projections using a matrix operation; and
controlling the advertisement disclosure to rotate by the direction of rotation and the angle of rotation, for rendering the advertisement disclosure to face the user.
