Information interaction method, interaction system and application

Abstract

The invention discloses an information interaction method, an information interaction system and application, and belongs to the field of electronic whiteboards. Aiming at problems that an electronicwhiteboard in a conference system in the prior art is large in transmission data, interactive bandwidth is high, the network requirement is high, the invention provides an information interaction method. A host sends the picture data to a local end and a remote end for display; when a picture is annotated locally, the host carries out serialization processing on the local annotation, sends the processed data to a far end; the far end is combined with the serialized data and the corresponding coordinates and pressure sensitive values; the graphic processor calculates and draws an image for display; the interactive method is applied to an electronic whiteboard of a conference system, only handwriting data are sent during writing, all participants receive the handwriting data and then displaythe handwriting data on a screen, and therefore multi-party real-time interactive whiteboard cooperation is achieved, and the interactive method is supported in a local conference and a teleconference.

Description

technical field [0001] The present invention relates to the field of electronic whiteboards, and more specifically, relates to an information interaction method, an interaction system and an application. Background technique [0002] Teleconferencing generally refers to video conferencing, where voice and video images are shared remotely and interactively. For the data interaction in the computer, the traditional way is to convert it into video and then transmit it, which will greatly reduce the image quality and real-time interactivity. With the development of digitization of conference content, an interactive writing system appeared in due course to make up for this deficiency. Teleconferencing systems mainly include teleconferencing, web conferencing, and video conferencing. [0003] In order to improve the participation and interaction of the participants in the meeting and improve the efficiency of collaborative communication, we often use some meeting electronic tool...
