Fixation point display method and related device

Abstract

The embodiment of the invention provides a fixation point display method and a related device. The method comprises the following steps: acquiring a basic display point coordinate, a real-time fixation point coordinate and a historical fixation point coordinate; then, according to a target inertial parameter, a first distance between the basic display point coordinate and the real-time fixation point coordinate, a second distance between the basic display point coordinate and the historical fixation point, a first sampling period difference value between the basic display point coordinate and the real-time fixation point coordinate, and a second sampling period difference value between the basic display point coordinates and the historical fixation point coordinates, calculating acceleration data of the basic display point coordinates; and finally, determining coordinates of a target display point according to the acceleration data and displaying the coordinates. The display point can be endowed with the physical attribute by adopting physical simulation, namely, the position of the target display point is determined by using a mechanical rule, so that the following performance can be ensured while the display jitter of the fixation point is reduced, and the user experience is greatly improved.

Description

technical field [0001] The present application relates to the technical field of eye tracking, in particular to a gaze point display method and related devices. Background technique [0002] With the development of technology, the application of eye tracking technology has gradually entered the public's field of vision. When determining the eyeball fixation point, due to the error of the external environment, the calculated eyeball fixation point will often be in a state of shaking. Point processing will cause the displayed eye gaze point to be in a state of jitter all the time, for example, with Figure 1A For example, it can be seen that although the actual gaze point is fixed, due to the small displacement of the human body relative to the mobile phone and the error of the proactive image, the gaze point output by the algorithm is not fixed, but is constantly changing in the area around the actual gaze point. jitter; and, another problem is the problem of delay, such as ...

[0002] With the development of technology, the application of eye tracking technology has gradually entered the public's field of vision. When determining the eyeball fixation point, due to the error of the external environment, the calculated eyeball fixation point will often be in a state of shaking. Point processing will cause the displayed eye gaze point to be in a state of jitter all the time, for example, with Figure 1A For example, it can be seen that although the actual gaze point is fixed, due to the small displacement of the human body relative to the mobile phone and the error of the proactive image, the gaze point output by the algorithm is not fixed, but is constantly changing in the area around the actual gaze point. jitter; and, another problem is the problem of delay, such as Figure 1B as shown, Figure 1B It represents an example in which the user's actual gaze point quickly shifts from the lower left corner of the screen to the upper right corner from t1 to t3. It can be seen that under the effect of median filtering, the movement of the gaze point output by the algorithm lags behind that of the actual gaze point. Speed, the faster the actual gaze point moves, the more obvious the lag

It can be seen that directly displaying the gaze point of the algorithm output will greatly affect the user experience
