Abstract

The embodiment of the invention provides a human eye sight line tracking method. The human eye sight line tracking method comprises the steps: obtaining human eye feature samples of a target human eye at a plurality of preset sight line positions at a current position; according to the human eye feature samples of the preset sight line positions at the current position and human eye features, obtained in advance, of multiple preset sight line positions, located at the reference position, of the target human eye on the screen, obtaining a function relation between the human eye feature samples of the preset sight line positions at the current position and the human eye features at the reference position; and obtaining target human eye features of the target human eye at an unknown sight line position on the screen at the current position, obtaining human eye features at a reference position corresponding to the target human eye features according to the function relationship, and obtaining the unknown sight line position according to the human eye features at the reference position corresponding to the target human eye features. According to the embodiment of the invention, real-time tracking is realized, and the tracking precision is high.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a method and device for tracking human eye sight. Background technique [0002] Eye tracking technology can provide an intuitive and easy-to-use human-computer interaction method, which is widely used in device verification and game interaction. For example, the user unlocks the device by controlling the movement track of the line of sight, and performs auxiliary operations of the game according to the direction of the line of sight. [0003] For eye tracking technology, the most important thing is to be able to accurately locate the position of the line of sight in real time. The traditional eye tracking technology uses infrared light source and camera to locate the line of sight. Infrared rays are reflected from the surface of the eyeball to the camera, which will change the imaging of the eyeball. The pupil of the human eye will turn white, and ...
