Method and apparatus for tracking gaze
Abstract:
A method for tracking a gaze includes determining a position of a first center point of a cornea by using at least two lighting reflection points detected from an eyeball area of a first face image of a user and calculating a first vector connecting at least two first image feature points detected from the first face image to the position of the first center point of the cornea. A position of a second center point of the cornea is determined using the first vector and a position of the feature point detected from the second face image. A second vector is determined using the position of the second center point of the cornea and a position of a center point of a pupil. The gaze of the user is tracked by using the second vector. An apparatus for tracking a gaze is also disclosed.
