[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] The embodiment of the present invention provides an interactive electronic whiteboard client for teaching. Figure 1 As shown, the interactive electronic whiteboard client corresponds to a physical classroom, is used for students in the physical classroom to log in as a classroom unit, has a lecturer business end interface and a server interface, and also includes: a display, a writing pen, an electronic eraser, a memory and several functional modules. Among them, the lecturer business end interface is used for the lecturer to log in to the current interactive electronic whiteboard client through the business end, and the server interface is used to connect to the electronic whiteboard client of the classroom assigned by the server, and synchronize with the electronic whiteboard client of the classroom.

[0036] As for the interactive whiteboard client described above, after the lecturer logs in, the lecturer's business terminal is synchronized with the current interactive whiteboard client, and the business terminal has the corresponding teacher operation authority for the client. The lecturer can operate the current interactive whiteboard client by operating the business terminal, and complete the interaction with the students in the classroom. At the same time, the lecturer can also temporarily change the operation authority of the current interactive whiteboard client through the business terminal, authorize the interactive whiteboard client logged in to the classroom, and allow the students logged in to the classroom to synchronously operate the current client through the local client to achieve interaction.

[0037] At the same time, the interactive whiteboard has a remote interface. When there are students in the classroom or login classroom corresponding to the client who cannot reach the physical classroom, the students access the client of the classroom through the remote interface, and then access the current interactive whiteboard client through the client.

[0038] Through the synchronization between the above-mentioned business end and the client, and the synchronization of the clients in different classrooms, students in different classrooms can participate in the lectures of the same teacher at the same time, and interact with the teacher and classmates.

[0039] The display of the interactive electronic whiteboard client is used to display handwriting, blackboard writing, classroom list and secondary student list under the classroom list, shared screen, etc.; the writing pen is an electronic pen, and its thickness, color and font can be set by itself. In addition, when the display is a touch screen, handwriting can be replaced by the writing pen for writing; the electronic eraser can be set in size and can also be set with a one-button clear function; the memory is used to store the client's teaching data for the client and server to call.

[0040] In a specific embodiment of the present invention, Figure 2 As shown, the interactive whiteboard client interface includes: "Demo Account", "New" and "Size and Color". Among them, the demo account integrates a menu function. After clicking, a row of specific function keys will appear, including: "Writing", "Picture", "Multi-pen", "Recognition", "Dictionary", "Blackboard Writing", "Interaction", and "Background Style". Each function key on the interface corresponds to a functional module of the client.

[0041] In this embodiment, for the convenience of description, the display is abbreviated as a whiteboard, that is, the display of the interactive electronic whiteboard client.

[0042] Click the "Write" button and the pen turns white. Figure 3 As shown, start writing directly on the whiteboard with a whiteboard marker or your finger. Figure 4 As shown, the blackboard can be enlarged, reduced, and translated by two-point operation of the fingers.

[0043] In this embodiment, the electronic eraser is called by long pressing the finger. Figure 5 As shown, press the interface with five fingers at the same time, and a white circular shape will appear. At this time, leave only one finger to press the interface and move it left or right. The white circle will move with it and erase the words you want to erase.

[0044] Click the "Graph" button to bring up the graph's secondary menu, such as Figure 6 As shown in the figure, the secondary menu includes: circle, straight line, angle, arbitrary triangle, equilateral triangle, right triangle, rectangle, square, coordinate axis, etc. Click the secondary menu button to draw different graphics; click the "Graph" button again to call out the graphic direct call interface, such as Figure 7 As shown in the figure, click on the graphics corresponding to different subjects to call them according to the course. For example, if you choose physics, the corresponding physics graphics are as follows Figure 8 shown.

[0045] "Multi-Pen" means when multiple students and / or teachers are operating the whiteboard at the same time, click this button to enable multiple people to operate simultaneously.

[0046] The "Recognition" key is used for handwriting recognition. When writing input is performed by finger touch, this key is clicked. The secondary menu of the "Recognition" key includes the writing font, font size, alignment, etc.

[0047] The "dictionary" is used to translate the input foreign language directly into Chinese.

[0048] The "blackboard writing" is used to call the blackboard writing. During the teaching process, the blackboard writing itself will be automatically saved and can be called out and used again at any time through the "blackboard writing". Just click to call the blackboard writing.

[0049] The "background style" is used to set the whiteboard background.

[0050] The "interaction" is used to call interactive message boxes and other applications. For example, call a PPT file and enter the slide show mode. In this mode, place one or more fingers on the screen to turn pages. Slide parallel to the left, and the PPT will automatically turn to the next page. Slide parallel to the right, and the PPT will automatically turn to the previous page. The page zooming operation is the same as the writing blackboard operation. When the interface is displayed at normal size, slide both index fingers to the middle at the same time to enter the slide browsing mode, which is convenient for selecting which page to open.

[0051] The secondary menu of "New" contains "Annotation". When you need to annotate an object, click the Annotation button and a secondary menu for setting the color and size of the writing pen will appear. To clear the annotated content, just use the erase function. The annotation function can annotate any open application, such as playing videos, web pages, office documents such as Word and PPT, pictures, etc. The annotated interface can be enlarged or reduced, and the annotated content will be automatically saved as a PNG picture by clicking the cross. Long press the menu button, click to open the annotation file, and call the storage path.

[0052] The embodiment of the present invention also provides an interactive electronic whiteboard service terminal for teaching. The electronic whiteboard service terminal has the same configuration and interface as the client, except that the service terminal is used for the login of the lecturer, has corresponding operation permissions and the authority to allocate permissions to the electronic whiteboard client corresponding to the classroom connected to the same client electronic whiteboard. The client interface is described in detail above, which will not be repeated here.

[0053] The embodiment of the present invention also provides an interactive electronic whiteboard server for teaching. Fig. 9 As shown, the server includes a client grouping module, a client synchronization module, a full resending module and a database.

[0054] The client grouping module is connected to the client, and is also connected to the client synchronization module and the full resend module, and is used to group the clients according to the client login data, and send the grouping information to the client synchronization module and the full resend module.

[0055] After receiving the grouping information, the client synchronization module allocates the client connections in the same group to the same path, that is, the interconnection between the clients in the same group is realized through the client synchronization module, and the information synchronization and interaction of the clients in the same group are realized. When synchronizing information between clients, the clients in the same group are equal, and any client can be used as a virtual client to synchronize all other clients in the group. In actual operation, the client connected to the service end is usually used as a unified virtual client to synchronize information.

[0056] The full resend module determines the time difference between the newly grouped clients and the original clients in the same group. If the time difference meets the predetermined time difference, it is determined to be joining the group midway, and the data within the time period of the current group stored in the database is retrieved from the current moment and returned to the time period of the group time difference, and the retrieved data is resent in full to the newly grouped clients. Through the independent setting of the full resend module, it does not conflict with the synchronization process between the clients realized by the client synchronization module. While realizing synchronization, the previous data can be retrieved to track the progress. When the classroom client that joins later or the electronic whiteboard client midway reconnects, the server can send the handwriting of the current group in full to ensure the synchronization of all whiteboard contents.

[0057] The embodiment of the present invention also provides an interactive electronic whiteboard system for teaching. Fig.10 As shown, the electronic whiteboard system includes: an electronic whiteboard service end, an electronic whiteboard client and an electronic whiteboard server.

[0058] Among them, the electronic whiteboard business end corresponds to the main teacher, and is randomly connected to any electronic whiteboard client for the main teacher to log in to the client through the business end; the electronic whiteboard client corresponds to the physical classroom, is set in the physical classroom, and is used for students or main teachers in the physical classroom to log in to the client in units of classrooms, and send the login information to the server; the electronic whiteboard server is connected to all electronic whiteboard clients for grouping the clients according to the received client login information, and to realize the interconnection and synchronization of the clients in the same group, and at the same time resend the previous data in full to the clients that join later.

[0059] When teaching interaction is carried out through the interactive electronic whiteboard system, the main teacher teaches a course in a classroom and first logs in to the electronic whiteboard client corresponding to the current classroom through the business terminal; the current electronic whiteboard client sends the login information to the server; other classrooms participating in this course log in to the local electronic whiteboard client through the account corresponding to the current course, and send the login information to the server; the server receives the login information of all clients, divides the clients with the same login characteristics into the same group, and returns the same group information to the clients in the same group to achieve interconnection between the clients in the same group. At the same time, the server acts as a medium to achieve information synchronization of the same group and interconnected clients; when the group divided by the login information received by the server has a time difference with the grouping state, full retransmission is initiated, and the data within the time difference is fully retransmitted to the clients that joined later to achieve true synchronization between clients.

[0060] The above description is only a preferred embodiment of the present invention and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present invention is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
