Embodiment Construction

[0053] Embodiments of the present application provide an eye tracking method combined with head motion detection and a related device, which can improve the accuracy of tracking and judgment of a terminal on a user's eye gaze point, and improve user experience.

[0054] see figure 1 , an embodiment of an eye tracking method combined with head motion detection in the present application includes:

[0055] 101. When the terminal detects that the user is staring at the screen, the terminal extracts the user's eye feature information through eye tracking technology, and calculates and obtains gaze point coordinates. The eye feature information includes pupil feature information and iris feature information, and the gaze Point coordinates reflect the user's gaze point on said screen;

[0056]Eye tracking technology refers to the technology of judging the moving direction and where of the user's sight by collecting the characteristic information of the user's eye. The key to eye t...

Abstract

The embodiment of the invention discloses an eyeball tracking method combined with head motion detection and a related device. The eyeball tracking method is used for improving the tracking judgment precision of a terminal on eyeball fixation points of a user. The embodiment of the method comprises the steps that when a terminal detects that a user is watching a screen, the terminal extracts eyeball feature information of the user through an eyeball tracking technology, and coordinates of a watching point are obtained through calculation; the terminal displays a visual feedback identifier on the screen, wherein the visual feedback identifier is used for prompting a user that the fixation point is located in an area; when the terminal detects that the fixation point is not in the target area, the terminal sets a head movement range by taking a preset value as a radius; the terminal detects head movement information of a user within the head movement range; and the terminal judges the head movement condition according to the head movement information, and corrects the fixation point coordinates and the visual feedback identifier according to the head movement condition.

Description

technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular to an eye tracking method combined with head movement detection and a related device. Background technique [0002] With the continuous popularization of smart devices, in the field of human-computer interaction, in addition to traditional touch and voice control, a new interaction method has emerged: eye tracking control. Eye tracking control means that the terminal estimates the direction and position of the user's gaze at the terminal by tracking the eyeballs, so as to realize the user's control of the terminal. For example: turning pages through eye tracking, controlling the lock screen time through eye tracking, and other operations. [0003] In the existing technology, eye tracking is mainly achieved by capturing the position of the eye through the camera, and then shooting a video, and analyzing the video to determine the gaze position and movin...
