The apparatus may include a camera array including a plurality of cameras, and a plurality of light sources for the plurality of cameras, a light source controller to control the plurality of light sources so that the plurality of cameras capture a bright pupil image and a dark pupil image of a user, a detector to detect a position of a pupil center of the user, and a position of a glint caused by reflection of the plurality of light sources from the captured bright pupil image and the captured dark pupil image, and an estimator to estimate an interest position of eyes of the user by tracking a gaze direction of the eyes, based on the detected position of the pupil center and the detected position of the glint..
Method and tracking user's gaze point using mobile terminal
A method for tracking a user's gaze point using a mobile terminal is provided. The method includes detecting the user's eye area from a camera that is mounted in the mobile terminal and selecting reference points of the eye area, detecting a pupil corresponding to an interest area that is obtained from the reference points, generating a first virtual grid of the eye area using a pickup image of a gaze point of the pupil corresponding to each corner of the display and generating a second virtual grid having the same division areas as those of the first virtual grid in the display, and mapping a position of the pupil within the second virtual grid area corresponding to a position of the pupil within the first virtual grid..
