Electronic whiteboard teaching system and method used for remote interaction

Abstract

The invention discloses an electronic whiteboard teaching system and method used for remote interaction. The electronic whiteboard teaching system comprises an electronic whiteboard, a server and a plurality of learning control terminals. The electronic whiteboard comprises an interaction module, a writing module, a manual identification module, a courseware storage module and a display unit. A wireless communication unit and a permissions validation unit are arranged in the interaction module. The learning control terminals comprise wireless communication units, operation control request subunits, control units and touch control display units connected to the control units. The server is provided with a wireless transceiver and a computer. The electronic whiteboard teaching system overcomes the defects in the prior art and is reasonable in layout; signals are transmitted to the server through the operation control request subunits of the learning control terminals, are transmitted to the electronic whiteboard via the server, are received by the interaction module of the electronic whiteboard and are validated through the permissions validation unit; once the signals meet the requirement, the system can accept remote control over writing, modifying and other operations, and therefore the teaching interaction effect is improved.

Description

technical field [0001] The invention relates to the technical field of digital teaching, in particular to a system and method for remote interactive electronic whiteboard teaching. Background technique [0002] The electronic whiteboard is a multimedia teaching equipment installed in the classroom or hall of the school for teaching. Electronic whiteboards are usually composed of desktop computers, touch interactive whiteboards, projectors, speakers, microphones and other electronic equipment. Moreover, the user can input information on the touch interactive whiteboard through a specific stylus instead of the mouse, such as editing, modification, or annotation, and send the information to the connected computer, so that the user can touch the interactive whiteboard through the electronic pen Editing, modifying or annotating the contents of the computer screen is realized through the operation of the computer, thus forming a large-screen, interactive collaborative meeting or ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned electronic whiteboard includes multiple devices such as a projector, a computer, and a speaker. Not only is the structural connection relatively complicated and cumbersome, it takes a lot of preparation time in the early stage, and the projection space occupies a large area, which is not conducive to teaching in small-sized classrooms. In addition, when using the electronic whiteboard for teaching, the user needs to stand in front of the electronic whiteboard to operate, which limits the user's activity space. Moreover, the electronic whiteboard lacks interaction with the audience during teaching, which is not conducive to improving teaching quality. effect; at the same time, the existing interactive electronic whiteboards can only demonstrate, annotate and write on the whiteboard of the main venue during interactive manipulation, and other remote venues can only be in the receiving state

As a result, the interaction of the entire distance teaching or training process is limited, which affects the effect of teaching or training
