Referring to fig. 5, fig. 5 is a flowchart illustrating an information transmission method according to a third embodiment of the present invention.
Based on the foregoing embodiments, in this embodiment, before the step S20, the method further includes:
step S01: carrying out eyeball tracking on a user through a camera to obtain the staying position of the eyeballs of the user;
it should be noted that the camera in this embodiment may be disposed on the second electronic device, and specifically may be disposed above, below, and the like a display screen on the second electronic device, and this embodiment does not specifically limit the specific position.
It is understood that the eyeball tracking refers to tracking the position of the eyeball of the user, and can be specifically tracked by the following method: the method comprises the steps of tracking according to the eyeball of a user and the characteristic change of the periphery of the eyeball, tracking according to the angle change of the iris, actively projecting light beams such as infrared rays and the like to the iris to extract the characteristics for tracking.
In a specific implementation, after the eyeball tracking is performed on the user, a position where the eyeball of the user stays on the display screen corresponding to the second electronic device can be obtained.
Step S02: obtaining the stay time corresponding to the stay position;
it should be understood that the stay time period refers to the stay time period corresponding to all the stay positions of the eyeballs of the user on the display screen.
Step S03: determining the use habit of the user according to the staying position and the staying duration;
the usage habit of the user refers to aesthetic preference of the user, and may specifically include shopping preference and favorite color of the user.
Further, in order to accurately determine the usage habits of the user, in the present embodiment, the step S03 includes: dividing a display area corresponding to the screen projection video into areas to obtain at least one area range; determining a target area range corresponding to the stopping position according to the area range; acquiring target stay time lengths corresponding to all stay positions in the target area range, and determining a visual hot area according to the stay time lengths; and determining the use habits of the user according to the visual hot zone.
It can be understood that the display screen corresponding to the second electronic device may not necessarily be played in a full screen manner, and therefore, in this embodiment, the display area for the screen projection video playing needs to be divided into regions, and the specific region division method may be to determine the length and width of the display area first, and then perform region division according to specific values of the length and width, so as to obtain at least one region range. For example: when the length and width of the display area are small, the display area can be divided into an upper area, a middle area and a lower area; when the length and width of the display area are large, the minimum area range may be determined to be 1 cm × 1 cm, and then the horizontal and vertical areas of the display area are divided, and the display area may be divided into an upper left area, a middle left area, a left and right area, a middle left area, a middle area, a middle right area, a lower left area, a lower middle area, a lower right area, and the like. For example: when the length and width of the display area are both 9 cm, the display area can be divided into 9 × 9 areas, and can also be divided into 10 × 10 areas, and the specific number of the divided areas can be set according to the actual situation.
It is understood that the target zone range refers to a zone range in which each stop position is located in the divided zone range. After the target area range is obtained, all the stay positions in the target area range can be obtained, and then the target stay durations corresponding to all the target area ranges are obtained, namely the sum of the stay durations corresponding to all the stay positions.
In specific implementation, the preset threshold may be preset in this embodiment, and the preset threshold may be set according to actual conditions, for example: 3 seconds, 5 seconds, etc., and this embodiment does not specifically limit this. When the target stay time is longer than the preset threshold, determining that the area range corresponding to the target stay time is the visual hot area.
