The characteristics of the bullet screen may include a display area of the bullet screen, font transparency, font size, moving speed and number, and the like.
During the process of watching the video, the eye movement data of the user can be acquired through the eye tracking technology.
The eye tracking is a scientific application technology for tracking eyeball changes in real time by positioning eyeballs through infrared equipment, cameras and other equipment. Because the eyes of a person change correspondingly when looking at different directions, the eye tracking technology extracts corresponding features by using the changes, and realizes the tracking of the eyeball movement of the person.
The eye movement data mainly comprises the real-time position of the gaze point of the eye.
The bullet screen played at this time is the currently played bullet screen.

Specifically, if the gaze point of the viewer is on the bullet screen content for a long time and on the media content for a short time, the gaze mode of the viewer is determined to be gaze mode one.
Gaze pattern-a gaze pattern that may be referred to as a "focus bullet screen".
The total watching time is the sum of the time of the watching point of the audience on the bullet screen content and the time of the watching point of the audience on the video content.
And determining whether the watching mode of the audience is a first watching mode according to whether the ratio of the duration of the watching point of the audience on the bullet screen content to the total watching duration is greater than a preset first threshold.
