Problems solved by technology

[0003] The current eye tracking is not very mature, and the focus tracking that falls on the screen in front of the eyes is not very accurate, which leads to delays or even failures in controlling corresponding operations based on eye tracking

Embodiment Construction

[0028] Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments.

[0029] like figure 1 As shown, a video interaction operation method based on eye tracking includes the following steps:

[0030] Step 1: Determine the coordinates P(x, y) of the operator relative to the screen, x represents the vertical distance of the operator from the screen, y represents the horizontal distance of the operator relative to the camera device for eye tracking, and the horizontal distance y is also That is, the horizontal distance of the operator relative to the screen. Determine whether the operator is within the preset position range according to P(x, y). If it is within the preset position range, continue to perform the following steps, otherwise, end the process. Wherein, the camera device can be installed at the central position of the top of the screen, and use a vertex of the screen as the origin to establish the K...

Abstract

The invention discloses a video interactive operation method based on eye tracking, comprising: determining the coordinates P(x,y) of the operator relative to the screen, and judging whether the operator is within a preset position range according to P(x,y), and if Within the preset position range, continue to perform the following steps, otherwise, end the process; determine the operator's face image, and intercept the ROI images of the left and right eyes from the face image. Face orientation, otherwise, judge the side face orientation, determine the left pupil and right pupil, and then determine the visual area where the operator's vision falls on the screen; Step 3: Determine the pupil change according to the ROI images of the two adjacent left and right eyes. The corresponding video interaction operation is performed according to the pupil change situation. The present invention can well determine the preset position range where the operator is located, accurately track the eyeball, and can better perform the video interaction operation.

Description

technical field [0001] The invention relates to the technical field of eye tracking, in particular to a video interactive operation method based on eye tracking. Background technique [0002] Most of the existing on-screen video interaction operations are achieved through mouse, keyboard or other physical hardware (such as VR handle) to achieve different operations, such as switching, closing, fast-forwarding and other video operations. However, this operation is not suitable in some scenarios. For example, for disabled persons with broken arms, the mouse and keyboard operation method is usually very inconvenient, and it is difficult for such persons to effectively control the screen for a long time. Therefore, if the screen can be controlled by eyeballs, the existing video interactive operation mode can be separated, it is more convenient for personnel to operate the screen content, and the cost of personnel and hardware can be well saved. [0003] The current eye tracking...
