Abstract
A display apparatus includes an infrared outputter configured to output infrared light toward a user, an image capturer configured to photograph the user to generate a captured image, and a controller configured to detect, from the captured image, a pupil and an iris of the user, and a glint area generated by the infrared light, and to determine, in response to the pupil, the iris, and the glint area being detected, a direction of the user's gaze based on a relation between a location of the pupil, and the glint area, and a size of the iris.
Claims20
A display apparatus comprising:
- an infrared outputter configured to output infrared light toward a user;
- an image capturer configured to photograph the user to generate a captured image;
- and
- a controller configured to:
- detect, from the captured image, a pupil of the user and a glint area generated by a reflection of the infrared light, and determine a direction of the user's gaze based on a distance between the pupil and the glint area;
- and
- detect an iris of the user from the captured image, compare a distance between central points of the pupil and the glint area with respect to a size of the iris, and determine the direction of the user's gaze based on a result of the comparing.
A method of controlling a display apparatus, the method comprising:
- outputting infrared light toward a user;
- photographing the user to generate a captured image;
- detecting, from the captured image, a pupil of the user, and a glint area generated by a reflection of the infrared light;
- determining, a direction of the user's gaze based on a distance between the pupil and the glint area;
- and
- detecting an iris of the user from the captured image, comparing a distance between central points of the pupil and the glint area with respect to a size of the iris, and determining the direction of the user's gaze based on a result of the comparing.
A gaze determining apparatus comprising:
- an infrared outputter configured to output infrared light toward a user;
- an image capturer configured to capture an image of the user;
- and
- a controller configured to:
- analyze the captured image to determine a location of a pupil of the user and a glint area generated by light reflected by an eye of the user from the output infrared light;
- detect an iris of the user from the captured image;
- compare a distance between central points of the pupil and the glint area with respect to a size of the iris;
- and
- determine a direction of the user's gaze based on a result of the comparing.
