Abstract

The invention discloses an eye movement tracking method and device, and belongs to the technical field of man-machine interaction. The method includes the steps of obtaining at least two frames of images; obtaining eye areas in the at least two frames of the images; positions of eye iris centers are determined in the eye areas of the at least two frames of the images respectively; positions of reference points are determined in the eye areas of the at least two frames of the images respectively; the reference points refer to points keeping static relative to the eye areas; eye movement tracking is carried out on the eye iris centers according to the positions of the eye iris centers and the positions of the reference points; the problem that an intrusion type eye movement tracking technology always needs extra hardware to assist in obtaining change situations of eye watching direction is solved; the eye movement tracking method and device achieve the effect of carrying out eye movement tracking by obtaining the images without the need of the extra hardware for assisting.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of human-computer interaction, and in particular to an eye tracking method and device. Background technique [0002] With the birth of new technologies and devices, the research on controlling mobile terminals to perform corresponding operations through eye-tracking technology on mobile terminals is becoming more and more well known. [0003] The fundamental problem with eye-tracking technology is measuring changes in the direction the eye is looking. There are many related invasive eye-tracking techniques, including pupil-corneal reflection vector method, electrooculogram method, iris-sclera edge method, corneal reflection tracking method, contact lens method and so on. For example, the pupil-cornea reflection vector method commonly used in human-computer interaction scenes, the principle of this method is as follows: when an infrared auxiliary light source is used to illuminate a per...
