In step S5, since the first offset information represents the basic displacement of the human eye vision and the second offset information represents the orientation of the human eye vision, the gazing area of the human eye on the display screen can be obtained according to the first distance information, the first offset information and the second offset information. The partitioned display system of this embodiment also enables fast tracking of the gazing area 11 because of the small number of types of data acquired.

Referring to fig. 4, in some embodiments, step S41 includes the steps of:
s411, acquiring second proportion information according to the first distance information, the preset third distance information and the preset fourth distance information;
s412, acquiring third offset information according to the second offset information, the second proportional relation and the second proportional information;
and S413, acquiring a fixation center point of human eyes on the display screen 1 according to the first offset information and the third offset information.

wherein β is the second ratio information, D is the preset fourth distance information, D 1 D is preset third distance information.
Step S412 first obtains a first actual offset of the pupil in the human eye when the distance from the human eye to the display screen 1 is a preset third distance information according to the second offset information and the second proportional information, and then obtains a second actual offset (i.e., third offset information) of the pupil in the display screen plane according to the first actual offset and the second proportional relationship, where the third offset information is an offset of the injection point in the display screen plane due to the change of the position of the pupil. The calculation formula of step S412 is shown as follows:
（4）
wherein the second offset information includes
And

And
and beta is the second ratio information,
representing the offset distance of the pupil in the image information in the x-direction in the human eye,

wherein the gaze center point comprises x and y,
representing the offset distance of the human eye in the x-direction in the plane of the display screen,
representing the offset distance of the human eye in the y-direction in the plane of the display screen,
representing the offset distance of the pupil in the x-direction in the plane of the display screen,
representing the shift distance of the pupil in the y-direction in the plane of the display screen, x representing the shift distance of the gaze center point in the x-direction in the plane of the display screen, and y representing the shift distance of the gaze center point in the y-direction in the plane of the display screen.

wherein the content of the first and second substances,
which represents the correction coefficient(s) of the image,

indicating the second distance information.

The calculation formula of step S412' is the same as equation (3).
In step S413', a first actual offset of the pupil in the human eye when the distance from the human eye to the display screen 1 is the preset third distance information is obtained according to the second offset information and the second proportional information, and then a second actual offset (i.e. the third offset information) of the pupil in the plane of the display screen is obtained according to the first actual offset and the second proportional relation. The calculation formula of step S413' is the same as that of equation (4).
Since the first offset information is an offset of the human eye with respect to the display screen 1, the third offset information is a second actual offset of the pupil in the plane of the display screen, and the correction coefficient can be used to correct the first offset information, step S414 can obtain the gazing center point according to the first offset information and the third offset information. The calculation formula of step S414 is shown as follows:
wherein the gaze center point comprises x and y,
which is indicative of a correction factor that is,
representing the offset distance of the human eye in the x-direction in the plane of the display screen,
representing the offset distance of the human eye in the y-direction in the plane of the display screen,
representing the offset distance of the pupil in the x-direction in the plane of the display screen,
representing the shift distance of the pupil in the y-direction in the plane of the display screen, x representing the shift distance of the gaze center point in the x-direction in the plane of the display screen, and y representing the shift distance of the gaze center point in the y-direction in the plane of the display screen.
