ABSTRACT:
An eyeball locating system includes a display panel, an application program and a matrix optical sensor. The matrix optical sensor is disposed in the display panel. The application program controls the matrix optical sensor, executing an eyeball locating method to measure the movement of an eyeball including an eye white and a pupil. The method includes: providing a default graph showing the change of light energy; defining a default characteristic value of the pupil according to the default graph; shining light on the eye white and the pupil, a part of the light reflected by the eye white and the pupil to form a reflecting light; detecting the reflecting light energy to form a measured graph showing the change of reflected light energy; calculating a measured characteristic value according to the measured graph; and comparing the default with the measured characteristic values to determine the change of the pupil.
