When the user needs to draw, write and edit a document, the user can edit the document on the lower screen through the electromagnetic pen.
When an internal conference is carried out (namely, remote video is not needed), the content displayed on the upper screen or the lower screen can be put on a large screen in a wired or wireless mode, and the large screen is convenient for multiple people to watch. When the characters and pictures need to be written and explained, the electromagnetic pen can be used for modifying and editing the lower screen and throwing the images on the large screen in real time. In this case, the lower screen is equivalent to a large electronic whiteboard, and the cost is much lower than that of the large electronic whiteboard.
And in the process of remote video, the remote end and the local end are respectively provided with a robot. Besides the function of an internal conference, the local end can synchronously transmit the content shot by the camera and the content displayed on the lower screen to the remote end, the remote end displays the content shot by the local camera on the upper screen of the remote end, and synchronously displays the content displayed on the lower screen of the local end on the lower screen of the remote end. When the local end uses the lower screen to draw, write and edit the document, the editing process is displayed on the lower screen of the remote end in real time, and the remote end can edit the content displayed on the lower screen of the local end and also transmit the content to the lower screen of the local end. Therefore, the interaction between the local end and the remote end through modes of remote writing, drawing and the like can be realized, the explanation can be realized along with the edition, and the understanding of the conference contents by both parties of the conference can be greatly improved. The problem that a desktop-level video system cannot synchronously interact with drawing, writing and document editing during remote video is solved.
Whether the lower screen needs to be synchronously displayed or not can be freely selected through a software UI interface, namely when the interpreter does not want to display the editing process in the writing, drawing and document editing processes, the lower screen content can not be displayed through software setting.
When the explanation person of video conference changes, can not remove the robot, through the sound localization function location explanation person's of mic array accurate position to through the direction of screen to explanation person on the rotating electrical machines autogiration, the long-range end of being convenient for attends the meeting personnel and can directly pay close attention to the explanation person, promotes experience effect.
