Electronic whiteboard control method, device and system, and computer-readable storage medium

Abstract

Embodiments of the present invention relate to a control method, device, and system for an electronic whiteboard, and a computer-readable storage medium. For example, the control method includes: creating an electronic whiteboard page in response to a user triggering operation; Position coordinates; in response to the size expansion of the electronic whiteboard page caused by the user's sliding operation, record the expansion direction of the electronic whiteboard page, and calculate the position coordinate value of the starting handwriting relative to the reference point based on the current coordinate value of the reference point to update the relative position coordinates; and in response to a user preset trigger operation, performing a page return operation on the electronic whiteboard page according to the updated relative position coordinates. The writing content according to the embodiment of the present invention is more efficient and accurate when locating the initial handwriting, and the user operation experience is better.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a control method for an electronic whiteboard, a control device for an electronic whiteboard, a control system for an electronic whiteboard, and a computer-readable storage medium. Background technique [0002] In the conference screen system, the electronic whiteboard function is the core requirement that must be realized. The user needs to write the presentation content on the electronic whiteboard in real time and present it to the participants, and often the size of the electronic whiteboard page design is almost infinite. After writing and swiping to switch the writing position next time, due to the large amount of writing content, if the user wants to return to the starting writing point (or the origin), he needs to continue to slide the screen several times to return along the original path until the writing content is reached. Stop sliding at the beginning ...

[0002] In the conference screen system, the electronic whiteboard function is the core requirement that must be realized. Users need to write and present the lecture content on the electronic whiteboard in real time and present it to the participants, and often the size of the electronic whiteboard page design is almost infinite. After writing and sliding to switch the writing position for the next time, due to the large amount of writing content, if the user wants to return to the starting writing point (or origin) at this time, he needs to swipe the screen multiple times to return along the original path until he reaches the writing content Stop sliding at the beginning to return to the origin; in this way, there will be the following disadvantages: (a) manual sliding to return to the origin is inefficient and poor user experience; and (b) when the sliding speed is fast, it will be easy to swipe Writing range, you need to slide again to locate the origin
