Problems solved by technology

However, in distance teaching, the interaction between the teacher on the lecture side and the students on the listening side is multi-faceted and comprehensive. For example, sometimes the teacher will open the software of the small game during class, and teach the students by letting the students operate the small game. relevant knowledge, but the existing electronic whiteboard function can only realize the synchronization of handwriting and other annotations between the speaker end and the listening end, and cannot realize the remote collaborative operation of software such as small games. Interaction reduces the degree of interaction and greatly reduces the teaching effect

Embodiment 1

[0048] like figure 2 As shown, the electronic whiteboard system of the present invention includes: a first terminal and a second terminal. An annotation such as handwriting can be synchronized between the first terminal and the second terminal. Wherein, the first terminal includes: a first transparent layer 11 and a first base layer 12, and the first transparent layer 11 is located above the first base layer 12;

[0049] The second terminal includes: a second transparent layer 21 and a second base layer 22 , and the second transparent layer 21 is located above the second base layer 22 .

[0050] Generally speaking, the second terminal is the teacher's terminal or the lecturer's terminal, and the first terminal is the student's terminal or the listening terminal. A speaker terminal is usually connected to one or more listener terminals. like figure 2 As shown, all handwriting operations performed by the first terminal are displayed on the transparent layer of the first te...

Embodiment 2

[0076] Corresponding to the method of Embodiment 1, such as image 3 As shown, the present invention also provides an electronic whiteboard system, comprising: a first terminal and a second terminal;

[0077] Wherein, the first terminal includes: a first transparent layer and a first bottom layer, the first transparent layer is located in the

[0078] above the first bottom layer;

[0079] The second terminal includes: a second transparent layer and a second base layer, the second transparent layer is located above the second base layer;

[0080] The first terminal also includes:

[0081] a video playback module, used for the terminal to receive the real-time screen video stream of the second terminal, and to play the video stream on the first bottom layer of the terminal;

[0082] a sending module, configured to send first operation information; wherein, the first operation information includes: operation events generated by the operation of the first transparent layer and...

Embodiment 3

[0096] Embodiments of the present invention further provide a storage medium on which computer instructions are stored, and when the instructions are executed by a processor, implement the control method of the electronic whiteboard system in any of the foregoing embodiments.

[0097] Those skilled in the art can understand that all or part of the steps of implementing the above method embodiments may be completed by program instructions related to hardware, the aforementioned program may be stored in a computer-readable storage medium, and when the program is executed, execute Including the steps of the above method embodiment; and the aforementioned storage medium includes: a mobile storage device, a random access memory (RAM, Random Access Memory), a read-only memory (ROM, Read-Only Memory), a magnetic disk or an optical disk and other various A medium on which program code can be stored.

[0098] Alternatively, if the above-mentioned integrated unit of the present inventio...

Abstract

The invention discloses a control method, system, equipment and storage medium of an electronic whiteboard system. The control method includes the steps of: the first terminal receives a real-time screen video stream of the second terminal, and plays the video stream on the first base layer of the first terminal; the second terminal receives a control mode instruction; the second terminal The control mode is switched according to the control mode instruction; when the control mode is the first control mode, the second terminal receives the operation information sent by the first terminal and executes the corresponding instruction on the second base layer according to the operation information ; wherein the operation information includes: an operation event generated by an operation on the first transparent layer and information on an operation point position generated by an operation on the first transparent layer. The invention is improved based on an electronic whiteboard that only synchronizes handwriting annotation, and realizes multi-terminal remote collaborative operation by capturing the user's operation information on the first transparent layer and transmitting it to the second terminal in real time to execute the corresponding operation.

Description

technical field [0001] The invention relates to the field of synchronous display of data, and more particularly, to a control method, system, device and storage medium of an electronic whiteboard system. Background technique [0002] With the development of information network technology, education has realized real-time or time-sharing distance teaching with the help of information network and related supporting technical equipment. In distance teaching, the electronic whiteboard can realize the common annotation between the lecturer and the listener, which greatly facilitates the interaction between the lecturer and the listener. However, in distance teaching, the interaction between the teacher on the lecture side and the students on the listening side is multi-faceted. For example, sometimes the teacher will open the software of the mini-game during class, and teach the students by letting the students operate the mini-game. related knowledge, but the existing electroni...
