example 1

[0207] Example 1: Page element operation event

[0208] L1, on the side of the local whiteboard, a writing event is detected (take writing element S0 as an example below).

[0209] L2, generating the element identifier of the target element S0, and sending the lock application of the element S0 to the server.

[0210] Among them, the element identifier can be an element ID, and the ID of each element is unique on the same whiteboard page.

[0211] It should be noted that, for a handwriting, the whiteboard can be erased by a bit or a line eraser. Point erase is to erase certain points, while line eraser is to delete the entire line directly. The wiping method may cause a handwriting to be divided into multiple sub-segments. In some embodiments, each sub-segment can be used as a new element to generate a corresponding element identifier.

[0212] The element lock application can carry the element identification of the target element S0; through the element lock application, the server ca...

[0234] Example 2: Page operation event

[0235] M1, on the side of the local whiteboard, a page operation event is detected (the following takes page P0 as an example).

[0236] M2: Obtain the page identifier of the page P0, and send a lock application for the page P0 to the server.

[0237] Among them, the page identification of the target page P0 may be carried in the page lock application; the page identification 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, according to the page identifier carried in the page lock application, query whether the page lock of page P0 and the element lock of each element in the target page P0 are allocated. If the query result is no, the page lock of the target page P0 is allocated to the requesting party Local whiteboard.

[0240] In some embodiments, the page lock application sent by the whiteboard also c...

Abstract

The invention relates to a whiteboard operation method, device and system, a whiteboard device and a storage medium, which are applied to the field of whiteboard devices. The method includes detectingan operation event occurring at a first whiteboard; if the target of the operation event is a page element, applying for an element lock of the target element; after the element lock of the target element is applied, displaying the result of the operation on the target element on the first whiteboard, wherein the target element is a page element for which the operation event is directed, and thetarget element does not belong to a page element for which the operation event of the second whiteboard is operating. The first whiteboard and the second whiteboard belong to the same shared meeting,and the pages displayed on the first whiteboard and the second whiteboard are same, thereby realizing the effect that a plurality of users simultaneously perform whiteboard at multiple whiteboard endsparticipating in the shared meeting. The embodiment of the invention solves the problem of low efficiency when multiple people operate the whiteboard in the shared meeting, and avoids the operation conflict when multiple people operate.

Description

Technical field [0001] The present 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 conference. Background technique [0002] The electronic whiteboard (referred to as whiteboard) is equivalent to an electronic handwriting board with a particularly large area. It generally requires a dedicated whiteboard software to support. Users can use fingers or pens to write and draw on the whiteboard display at will. The electronic whiteboard display will The content written by the user is displayed, and the displayed content can be erased electronically. In addition, the whiteboard can also be connected to a mobile phone, a PC or other external devices through a network, and can be used in classroom teaching, on-site presentations, or remote meetings. [0003] In the process of implementing the present invention, the inventor found the following problems in the prior a...
