Method for realizing synchronization of electronic whiteboards

Abstract

The invention belongs to the technical field of networks, in particular relates to a method for realizing synchronization of electronic whiteboards, comprising the following steps of: when a user writes on a whiteboard, beginning to record the coordinate of a mouse on the whiteboard and a beginning mark in an array variable when the mouse is pressed down; when the mouse is in the moving process, recording the coordinate of a mouse on the whiteboard into the array variable; when the mouse bounds, recording the coordinate of a mouse on the whiteboard and an ending mark into the array variable; meanwhile, acquiring n records from the array variable by a program and sending the n records to other whiteboard ends needed to be synchronized through Socket, and removing the n records from an array; after a whiteboard receives a message, converting the coordinate into a line through film chip to be displayed on the whiteboard. By using the method, the electronic whiteboards can be rapidly synchronized, and the method has rather strong timeliness, accuracy and high efficiency.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method for realizing synchronization of electronic whiteboards. Background technique [0002] The development of Internet technology enables us to realize instant messaging, chat with friends, negotiate with partners and so on without leaving home. At present, based on the instant messaging tools that need to be downloaded and installed, such as MSN, QQ, and Netease Bubbles, they have been deeply loved by everyone. It provides a new way for people to communicate and exchange information. Another important way of information exchange. With the help of these tools, users can realize single-person or multi-person video, hold online video conferences, conduct online distance education, and greatly reduce the cost of communication between people and improve efficiency. [0003] Text communication, audio communication, and video communication are the three most importa...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many electronic whiteboard products on the Internet. For example, whiteboards in instant messaging tools are all one-way, that is, after editing a picture, the generated picture is sent to the other party, which cannot realize real-time whiteboard. comminicate

At present, there are also many video conferencing and distance education systems that realize real-time synchronous electronic whiteboards, but these whiteboards need to download software for installation, and have certain requirements for software, hardware, and costs. These are the shortcomings of the current electronic whiteboard functions.
