the time determining subunit is used for acquiring a time difference value between the current time and the answer starting time, acquiring the remaining time based on the difference value between the preset answer interval time and the time difference value, acquiring the demonstration content of the current demonstration page, determining the number of knowledge points to be explained, and determining the explanation speed of a teacher in the lecture based on the historical screen recording video of the teacher in the lecture;
and predicting the demonstration time of the current demonstration page according to the number of the knowledge points to be explained and the explanation speed, obtaining the residual explanation waiting time based on the difference between the residual time and the demonstration time, and inserting the page to be inserted into a first interactive information demonstration template currently displayed by a display module in the residual explanation waiting time.
9. The intelligent whiteboard system with interactive function of claim 1, wherein the screen recording backup module comprises:
the triggering unit is used for triggering a recording permission obtaining instruction when demonstration text content appears on a display page of the intelligent whiteboard and obtaining the opening permission of the recording equipment;
the recording unit is used for setting content to start corresponding recording equipment based on the starting authority of the recording equipment and recording the explanation content of the lecture teacher based on the recording equipment;
and the sending unit is used for sending the recorded content to the course data storage module for storage when the lecture teacher finishes the explanation.
10. An intelligent whiteboard interaction method with an interaction function is characterized by comprising the following steps:
step 1: acquiring whiteboard interaction information in a current synchronization packet based on an information synchronization network;
step 2: screening the whiteboard interaction information to obtain effective interaction information, and uploading the effective interaction information to a display module;
and step 3: when the lecture teacher explains based on the display module display content, the screen recording function is started to record and store the explanation content of the teacher, and when the lecture teacher finishes explaining, the recorded content is sent to the course data storage module to be stored.
