example 1
[0207] Example 1: Page element operation event
[0208] L1, on the side of the local whiteboard, a writing event is detected (the writing element S0 is taken as an example below).
[0209] L2: Generate an element identifier of the target element S0, and send a lock application for the element S0 to the server.
[0210] Wherein, the element identifier may be an element ID, and in the same whiteboard page, the ID of each element is unique.
[0211] It should be noted that for a piece of handwriting, the whiteboard can be erased by point or line. Erase by point is to erase some points in it, and erase by line is to delete the entire line directly. The rubbing method may cause a piece of handwriting to be divided into multiple sub-sections. In some embodiments, each sub-section may be used as a new element to generate a corresponding element identifier.
[0212] The element lock application can carry the element ID of the target element S0; the element lock application can trigg...

[0234] Example 2: Page action event
[0235] M1, on the side of the local whiteboard, a page operation event is detected (page P0 is taken as an example below).
[0236] M2. Obtain the page identifier of the page P0, and send a lock application for the page P0 to the server.
[0237] Wherein, the page lock application may carry the page identifier of the target page P0; the page identifier may be a page number, and different pages have different page numbers.
[0238] M3, on the server side, receives the page lock application for page P0 sent by the local whiteboard.
[0239] M4. Query whether the page lock of page P0 and the element locks of each element in the target page P0 are allocated according to the page identifier carried in the page lock application. If the query results are all negative, allocate the page lock of the target page P0 to the applicant Local whiteboard.
[0240] In some embodiments, the page lock application sent by the whiteboard also carries the me...

Abstract
The invention relates to a whiteboard operation method, device, system, whiteboard equipment and storage medium, and is applied in the field of whiteboard equipment. The method includes: detecting an operation event that occurs on the first whiteboard; if the target of the operation event is a page element, applying for an element lock of the target element; after applying for the element lock of the target element, displaying a pair of The operation result of the target element; wherein, the target element is the page element targeted by the operation event, and the target element does not belong to the page element being operated by the operation event of the second whiteboard; the first whiteboard and the second whiteboard They belong to the same shared conference, and the pages displayed by the first whiteboard and the second whiteboard are the same, so that multiple users can simultaneously operate the whiteboard on multiple whiteboard terminals participating in the shared conference. The embodiments of the present invention solve the problem of low efficiency when multiple people operate the whiteboard in a shared conference, and avoid operation conflicts when multiple people operate the whiteboard.
Description
technical field [0001] The invention relates to the technical field of whiteboards, in particular to a whiteboard operation method, device, system, whiteboard equipment and storage medium in a shared meeting. Background technique [0002] An electronic whiteboard (referred to as a whiteboard) is equivalent to an electronic writing board with a particularly large area. Generally, it needs a special whiteboard software support. Users can use fingers or writing pens to write and draw on the whiteboard display at will. The electronic whiteboard display will show The content written by the user is displayed, and the displayed content can be electronically erased. In addition, the whiteboard can also be connected to a mobile phone, PC or other external devices through the network, and can be used in classroom teaching, on-site demonstration or remote conference and other scenarios. [0003] In the process of realizing the present invention, the inventor found the following proble...
