Research on Eye-Movement Control System Based on Eyeglass-Based Eye-Tracking Device

With the rapid development of computer hardware and software technology, eye movement technology has gradually become a major research hotspot. Eye movement control through eye tracker detection and processing application plays an important role in many fields. This paper mainly focuses on the use of eye trackers, development of gaze positioning and tracking algorithms, and design of eye movement control system. The system is mainly based on the principle of the pupil-cornea reflection method, including procedures such as extracting the pupil center and cornea reflection coordinates from the eye diagram, forming the pupil-cornea reflection vector to represent the direction of sight, and then establishing a gaze point mapping model through the calibration link. By using this model, the sight of eyes is converted into the gaze point on the display screen, and the state of eyes is detected to realize the control of gaze target.
