It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
In the prior art, some platforms also implement interaction with audiences by sending text messages in an interactive manner such as message leaving, barrage, forum, and the like. Through the interaction mode, the participation degree of the audience to the online live broadcast content is increased, and the interaction between the teacher and the students is realized. However, in this interactive mode, the teacher needs to pay attention to the messages sent by the students, which affects the teacher's live teaching progress. Based on the above, the method for detecting the student class attending state in the live broadcast teaching process obtains the wearing state of the corresponding student earphone through the wearing detection module, and determines the class attending state of the student according to the corresponding wearing state information; the corresponding lecture listening state is sent to a teacher end so that the teacher can know the student state in real time; can further help the teacher to know the live teaching effect of oneself to adjust the teaching mode.
Fig. 1 is a flowchart of a method for detecting a student attendance state in a live broadcast teaching process according to an embodiment of the present application, where the method for detecting a student attendance state in a live broadcast teaching process according to the present embodiment may be performed by a device for detecting a student attendance state in a live broadcast teaching process, the device for detecting a student attendance state in a live broadcast teaching process may be implemented in a software and/or hardware manner, and the device for detecting a student attendance state in a live broadcast teaching process may be formed by two or more physical entities or may be formed by one physical entity. Generally speaking, the device for detecting the student attending state in the live teaching process can be a computer, a mobile phone, a tablet or a background server and the like.
The following description will be given by taking an example in which the background server is a device for performing a method of detecting a student's lecture listening status in a live teaching process. Referring to fig. 1, the method for detecting the student attending state in the live broadcast teaching process specifically includes:
s101: and acquiring wearing state information of all the student earphones detected by the wearing detection module.
When the scheme of the embodiment is implemented, students need to log in an account and select a corresponding live broadcast room for live broadcast watching; similarly, the student earphones need to be connected with corresponding computers, signals detected by the student earphones are associated with the student account numbers, and then information is sent to the background server. Through the steps, the signals detected by the earphone of the student can be accurately corresponding to the specific student, and the background server can conveniently confirm the information source. In this embodiment, the wearing detection module may have a plurality of setting modes, and the main purpose of the wearing detection module is to perform earphone status monitoring.
Exemplarily, the wearing state information includes whether the headset is in a wearing state, the wearing detection module includes an acceleration detection module, fig. 2 is a schematic flow diagram for acquiring the wearing state information provided in the embodiment of the present application, and as shown in fig. 2, the acquiring the wearing state information of all the student headsets detected by the wearing detection module includes:
s1011: acquiring earphone acceleration signals of the student earphones detected by an acceleration detection module;
s1012: matching the earphone acceleration signal with a preset human body respiration signal;
s1013: and if the earphone acceleration signal is successfully matched with the human body respiration signal, determining that the student earphones are in a wearing state.
When the earphone is worn, the earphone is generally attached to a human body, and in the whole process, a person can breathe, so that the breathing of the person can drive the earphone to move regularly; however, if the student does not wear the headset, the headset is in a stationary state and the measured acceleration signal is zero. Therefore, the acceleration signal of the earphone is monitored through the acceleration sensor, the acceleration signal is matched with the breathing signal of a person, if the acceleration signal of the earphone is successfully matched with the breathing signal of the person, namely the acceleration signal of the earphone is the same as the breathing signal of the person or the difference value of the acceleration signal of the earphone is within a preset range, the fact that the student wears the earphone can be determined, and if the detected acceleration signal of the earphone is different from the breathing signal of the person or the detected acceleration signal of the earphone is zero, the student can know that the student does not wear the earphone.
Further, fig. 3 is a schematic flow chart of matching an acceleration signal of an earphone and a breathing signal of a human body provided in the embodiment of the present application, and as shown in fig. 3, matching the acceleration signal of the earphone and a preset breathing signal of the human body includes:
s1012a: detecting whether the earphone acceleration signal is a periodic signal;
s1012b: if the earphone acceleration signal is a periodic signal, acquiring the frequency of the earphone acceleration signal;
s1012c: and matching the frequency of the earphone acceleration signal with the frequency of the preset human body respiration signal.
The above is a specific manner of comparing the acceleration signal with the breathing signal of the human body, because the breathing of the human body is regular, when the student wears the earphone, it can be known that the acceleration signal detected by the acceleration sensor at the earphone is also a periodic signal. The breathing frequency of a normal human body is 16-18 times per minute, and when the acceleration signal is detected, the change of the acceleration signal per minute can be detected to be about 16-18 times. If the detected frequency is the same as this, it may be determined that the students wear the earphones, and if the detected frequency is different from the preset breathing frequency, it may be determined that the corresponding students do not wear the earphones.
In addition to the wearing detection mode through acceleration, the sleep detection can be performed through acceleration, and when a person is in a sleep state, the metabolism capability is relatively weak, and the corresponding breathing frequency is also reduced; therefore, the detection and matching can be directly carried out on the respiratory frequency of the human body, when the respiratory frequency of the human body is reduced, the corresponding student can be judged to be in a sleeping state, and a teacher is reminded to pay attention to the condition of the student.
In addition to the wearing detection method, this embodiment provides another embodiment, specifically, the wearing state information includes whether the earphone is in a wearing state, the wearing detection module includes a capacitive sensor, and the acquiring wearing state information of all the student earphones detected by the wearing detection module includes:
acquiring a capacitance signal between the student earphone and the skin of a corresponding student detected by a capacitance sensor;
and if the capacitance signal is consistent with the preset capacitance, determining that the corresponding student earphone is in a wearing state.
When the capacitance sensor is arranged, the capacitance sensor is arranged on the part, attached to the skin, of the inner side of the earphone. Thus, the capacitance signal between the earphone of the student and the skin of the student can be detected, if the earphone is in a wearing state, one capacitance signal can be detected due to the proximity of the earphone and the skin of the student, and if the earphone is not attached to the skin of the student, a different capacitance signal can be detected. Whether the student earphones are in a wearing state can be further determined according to the received capacitance signals. In addition to the acceleration sensor and the capacitance sensor, an infrared proximity sensor or the like may be provided for detection.
In addition to the wearing/non-wearing detection, it is more preferable to detect the wearing time and the number of times of picking up. The wearing state information also comprises the wearing time of the earphone and the picking times of the earphone;
the earphone wearing time and the earphone picking times are obtained through the following steps:
acquiring time information of the wearing state of the student earphones in the live broadcast teaching process, and obtaining the wearing time of the earphones according to the time information.
In the live broadcasting teaching process, when students wear earphones, corresponding timers are correspondingly started to time the wearing time, and if the students take off the earphones midway, the timers are controlled to stop working; if the student again puts on the headset, then control starts the timer. Acquiring corresponding timing time through the process, wherein the timing time records corresponding earphone wearing time; the concentration degree of the student attending class can be determined through the wearing time of the earphones.
Acquiring the number of times of change of the wearing state and the non-wearing state of the student earphones in the live broadcast teaching process, and acquiring the earphone picking number of times according to the number of times of change.
In the live broadcast teaching process, when a student takes off the earphone in a wearing state, the timer is controlled to work to perform an adding operation, when the student puts back the earphone in a non-wearing state, the timer is also controlled to perform an adding operation, and the times of taking off and wearing the earphone by the student in the whole process are obtained through the timer; however, in actual operation, the whole process of wearing-picking-wearing is usually counted as picking, so that the number of times of conversion needs to be divided by 2 to obtain the corresponding number of times of picking of the earphones when the calculation is performed.
S102: and confirming the class attending state of the student according to the wearing state information.
The wearing state information comprises wearing, wearing time and picking times; confirming the lecture listening state of the student through the three dimensions; in the present embodiment, descriptions of three listening states, a careful listening state, a normal listening state, and an unfair listening state are provided. The confirmation of the specific lecture listening state is carried out through the three state dimensions.
More preferably, the lecture listening state comprises a first lecture listening state, a second lecture listening state and a third lecture listening state; fig. 4 is a schematic flow chart of determining a student listening state according to wearing state information according to an embodiment of the present application, and as shown in fig. 4, the determining the student listening state according to the wearing state information includes:
s102a: when the wearing time of the earphones is greater than first preset time and the picking times of the earphones are less than first preset times, confirming that the corresponding students are in a first class listening state;
s102b: when the wearing time of the earphones is between a first preset time and a second preset time or the picking times of the earphones are between a first preset time and a second preset time, determining that the student is in a second class listening state;
s102c: and when the wearing time of the earphones is less than a second preset time or the picking times of the earphones are more than a second preset time, the students are confirmed to be in a third class listening state.
For example, in a 40 minute live teaching, if the student is attending a class, the student will be in a careful class for at least 38 minutes, and the number of times the student picks up the earphones during this process should be less than twice. Because the lectures are given by the online live broadcasting mode, but because the lectures are located at home, the possibility of interruption exists in the process; for example, when the user thinks about a certain idea while listening to a class, the user may take off the earphone and leave the live classroom for a short time when going to a desk to find related data, but the time is not likely to be too long. Therefore, a first preset time and a first preset number of times, such as 38 minutes and 2 times, are set as the criteria for the judgment. When the time is longer than 38 minutes and the number of times of picking up the earphones is less than 2 times, the student is seriously attending lessons in the whole process, and a teacher is attractive in teaching lessons.
However, not all students can keep on the above-mentioned state of carefully attending lessons, so in this embodiment, the second preset time is set to be 30 minutes, and the second preset times is set to be 6 times; when the wearing time of the earphone is between 30 minutes and 38 minutes or the picking frequency of the earphone is between 3 times and 5 times in the live broadcast teaching process of 40 minutes, the student can be in a common class listening state.
Some students do not concentrate on the live broadcast teaching content in the whole live broadcast process, the wearing time of the earphones is less than 30 minutes, or the picking times of the earphones are more than 6 times; it indicates that in the whole live broadcasting process, the corresponding students are not concentrated in the classroom, but are interrupted by the outside continuously, so that the live broadcasting teaching effect is influenced.
The above may also be that the student status is updated every 10 minutes, if every ten minutes, the first preset time is 9 minutes, and the picking times is 1; the second preset time is 7 minutes, and the picking times are two times. The specific time setting can be adjusted according to actual conditions, and the state information of the students can be updated at intervals.
Besides the specific time and picking frequency setting mode, the setting mode can also be set according to the proportion of the wearing time to the total live broadcast time; since not all live teaching is 40 minutes, it is necessary to set a ratio, for example, the first preset ratio is 98%, and only when the ratio of the time of wearing the earphones to the total duration of the live teaching exceeds 98%, it can be said that the student is in class seriously.
The actual lecture listening state of students in all live rooms can be reflected through the steps, so that teachers can know the student state conveniently, and the teaching progress of teachers cannot be influenced.
Further, fig. 5 is a schematic flow chart of confirming a live teaching effect provided in an embodiment of the present application, and as shown in fig. 5, after confirming a lesson listening status of a student according to the wearing status information, the method further includes:
s1021: acquiring the lecture listening states of all students;
s1022: calculating to obtain a corresponding first lesson listening state ratio, a second lesson listening state ratio and a third lesson listening state ratio according to the lesson listening states;
s1023: and determining the live broadcast teaching effect according to the sum of the first class listening state ratio and the second class listening state ratio.
The steps are to evaluate the effect of the live lecture of the teacher. Because the lecture listening state of each student can be acquired, the whole lecture listening situation of the students aiming at the whole live broadcast can be known by combining the lecture listening states of all students. For example, in listening to the language class of teacher a, in a live class of 40 people, 16 people are in class seriously, 20 people are in a common class state, and 4 people are not in class seriously; then it can be known that 36 people can always receive the complete information content in the live education process. Similarly, when 40 people listen to the Chinese class of the teacher B in the live broadcast room, 25 people listen to the class seriously at this time, 11 people listen to the class commonly, and 4 people do not listen to the class seriously; it can also be known that 36 people can always receive the complete information content in the live teaching process. However, the number of people who attend the class seriously during the course of the teacher B is more, so that the teaching effect of the teacher B can be judged to be better. If 10 people do not listen to the class seriously in the process of the teacher C, the teacher C can know that the teaching effect of the teacher C is not good, and needs to ask the teacher A or the teacher B to teach, so that the classroom attractiveness is improved. Through the above steps, the live-broadcast teaching result of the teacher can be determined more quantitatively, the teacher is helped to analyze and improve the teaching mode, the teaching effect of different teachers aiming at the same content can be compared, and the teaching effect condition obtained when different courses are taught can be conveniently aimed at the same teacher. Through the direct broadcast achievement show for the mr also can know that there are not enough in those places of oneself in the lecture, and then improves the live broadcast classroom appeal.
