Problems solved by technology
[0002] The use of the projector will inevitably require the cooperation of the electronic whiteboard to realize the function of online interaction. The existing electronic whiteboard is used separately from the projector. Computers are usually fixed and cannot adjust the distance from the electronic whiteboard, so sometimes it is impossible to project all the projected content on the electronic whiteboard. The existing electronic whiteboards are fixed and cannot be moved and cannot be adjusted in height, which limits the use of electronic whiteboards. scope

Description
technical field [0001] The invention relates to an online interactive electronic whiteboard, which belongs to the technical field of electronic whiteboards. Background technique [0002] The use of the projector will inevitably require the cooperation of the electronic whiteboard to realize the function of online interaction. The existing electronic whiteboard is used separately from the projector. The computer is usually fixed and cannot adjust the distance from the electronic whiteboard, so sometimes it is impossible to project all the projected content on the electronic whiteboard. The existing electronic whiteboards are fixed and cannot be moved and cannot be adjusted in height, which limits the use of electronic whiteboards. scope. [0003] An online interactive electronic whiteboard is now being studied, which can prevent the projection content of the projector from being blocked, and can also adjust the projection distance between the projector and the electronic whi...
