Abstract:
Provided is a gaze tracking apparatus for a user wearing a vision aid, the apparatus including a lighting element unit including a first infrared lighting element and a second infrared lighting element to radiate an infrared light to a user, an image acquirer to acquire an eye image of the user, the eye image including a first corneal reflection light, a second corneal reflection light, a first lens reflection light, and a second lens reflection light, and a processor to turn off the second infrared lighting element when interference occurs between the second lens reflection light and the first corneal reflection light in the acquired eye image, to and to compute a gaze position of the user based on user calibration information, and coordinates of the first corneal reflection light.
Abstract:
A gaze tracking apparatus and method are provided that may calculate a three-dimensional (3D) position of a user using at least two wide angle cameras, may perform panning, tilting, and focusing based on position information of the user and eye region detection information, using a narrow angle camera, may detect pupil center information and corneal reflected light information from an eye image acquired through an operation of the narrow angle camera, and may finally calculate gaze position information from the pupil center information and the corneal reflected light information.
