Abstract: An eye tracking device includes: a front camera which is positioned to face the front of a user to create a front image; an eye camera which is positioned to face the eyes of the user to create an eye image; a processor which tracks the gaze of the user with reference to the eye image according to pre-defined instructions, and points an object on the front image corresponding to the gaze of the user; and a memory which stores the instructions. The instructions are defined to perform the steps: extracting first pupil coordinates from the eye image when a user gazes at the vertexes of a pre-specified rectangle; calculating the coordinates of the front image corresponding to the first pupil coordinates according to a pre-specified transformation formula; calculating an error between the coordinates of the front image and reference coordinates that are the coordinates of the vertexes; creating a corrected transformation formula by correcting the transformation formula so as to reduce the error; extracting second pupil coordinates from the eye image; calculating the coordinates of the front image corresponding to the second pupil coordinates according to the corrected transformation formula; and pointing an object corresponding to the coordinates of the front image.
