Abstract
The present disclosure in at least one embodiment provides a method of providing an advertisement disclosure for advertisement identification to a content that is displayed in a three-dimensional space by a visual interface, including detecting an advertisement object located within a user sight from the content, inserting the advertisement disclosure in an adjacent position to the advertisement object, and controlling the advertisement disclosure in position or orientation based on a user gaze upon detecting the user gaze.
Claims10
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.
An apparatus for providing content with an advertisement disclosure for advertisement identification, comprising:
- an interface unit configured to display, in a three-dimensional space, the content including a plurality of virtual objects;
- a gaze detection unit configured to track a user's pupil and to detect a user gaze indicating a direction in which the user looks at one or more of the virtual objects;
- and
- a control unit configured to detect, from the content, an advertisement object located within a user sight, to insert the advertisement disclosure for advertisement identification in an adjacent position to the advertisement object, and to control the advertisement disclosure in position or direction based on the user gaze,
- wherein the control unit is configured to generate, in a three-dimensional space, a triangle using an origin, user coordinates, and advertisement disclosure coordinates obtained by the inserting of the advertisement disclosure, generate orthogonal projections for the triangle on an x-y plane, a y-z plane and a z-x plane, respectively, calculate a direction of rotation and an angle of rotation of the advertisement disclosure for each of the orthogonal projections using a matrix operation, and control the advertisement disclosure to rotate by the direction of rotation and the angle of rotation, for rendering the advertisement disclosure to face the user.
