Network public whiteboard system and method based on cloud computing

Abstract

The invention discloses a network public whiteboard system based on cloud computing, and the system comprises terminals and a network public whiteboard platform, wherein the terminals communicate with the network public whiteboard platform through a browser, the network public whiteboard platform further comprises a transmitting unit, a foreground U1 unit and a network public whiteboard processing unit, the foreground U1 unit at least comprises a display subunit and an interaction subunit, the display subunit is used for displaying the data in the browser of the terminals, and the interaction subunit is used for intercepting and capturing input operation on the browser of the terminals through a message hook and sending the input operation to the network public whiteboard processing unit through the transmitting unit; and the network public whiteboard processing unit is used for receiving operation data on the browser of the terminals, processing requests of different users, coordinating the parallel processing of the users, transmitting the processing result through the transmitting unit and displaying the processing result on the corresponding terminal browser through the foreground U1 unit.

Description

technical field [0001] The invention relates to a cloud computing technology, in particular to a cloud computing-based network public whiteboard system and method. Background technique [0002] In collaborative work, all computers participating in the collaboration may have a virtual public view, and the content on the view can be simple hand-drawn graphics, text, images, audio and video. When a user modifies the data in the view, the update result is immediately reflected on the views of other participating users. This virtual public view is called an electronic whiteboard, or a network public whiteboard. Due to this feature, through the electronic whiteboard, both data sharing and various interactions can be realized. The construction of the network provides a good platform for the use of electronic whiteboards, through which resource sharing and various interactions can be realized. [0003] The whiteboard can respond to the user's drawing operation and display it on ...
