As shown in fig. 5, when the sitting posture profile of the student deviates from the standard sitting posture, the sitting posture is prompted to be inclined by the swinging little bear pattern in the live-broadcast course interface.
Furthermore, the invention can calculate and prompt the correction mode of the sitting posture of the student. After step S3 the method further comprises the following step S4.
And S4, prompting the correction mode of the sitting posture of the student according to the position of the sitting posture of the student deviating from the standard sitting posture.
Specifically, a coordinate system of a plane where the sitting posture image of the student is located can be established, the position of the standard sitting posture in the coordinate system is determined, and when the sitting posture profile of the student deviates from the standard sitting posture, the position of the sitting posture of the student deviating from the standard sitting posture is calculated. Specifically, the position of the student sitting posture deviating from the standard sitting posture can be represented according to the distance between the coordinate of the center point A1 of the standard sitting posture corresponding to the student outline and the coordinate of the center point A2 of the standard sitting posture corresponding to the student outline after deviation and the included angle between A1A2 and the horizontal line. Prompting the correction mode of the sitting posture of the student according to the direction opposite to the position of the sitting posture of the student deviating from the standard sitting posture. The correction mode comprises a correction distance and a correction angle. For example, if the position of the sitting posture of the student deviated from the standard sitting posture is 5CM and the included angle between the position and the horizontal line is 15 degrees, the correction mode of prompting the coordinates of the student is as follows: 5CM, and forms an included angle of-15 degrees with the horizontal line.
The invention can further count the sitting posture profile data of students in different age groups; wherein the student seating posture profile data may include: the proportion of students whose sitting posture profiles do not deviate from the standard sitting posture (namely, the sitting posture is kept correct) in each live class, the time interval of the sitting posture profiles of the students deviating from the standard sitting posture and the like. When a new course setting is needed by a teaching and research group, a user course setting instruction can be input through a course setting button in the APP, and when the user course setting instruction is received, the reference time length of live broadcast courses in different age groups and/or the reference time length of rest between two continuous live broadcast courses are determined and displayed according to the student sitting posture profile data. For example, in the live lessons with different time lengths (such as 30 minutes, 40 minutes and the like), the proportion of students with correct sitting postures is counted, and the maximum proportion of students with correct sitting postures in the live lessons is determined as the reference time length of the live lessons. And counting the time interval of the deviation of the sitting posture profile of the student from the standard sitting posture, and taking the time interval with the maximum number of times of correcting the sitting posture of the student as the rest reference time length between two continuous live broadcast classes.
