the starting and detecting module: the system comprises a screen display interface, a user gesture detection program and a gesture recognition program, wherein the screen display interface is used for starting the user gesture detection program on the screen display interface of the electronic whiteboard based on a user calling instruction and detecting the current gesture information of a user;
a judging module: the gesture information is used for judging whether the detected gesture information is gesture information for calling the movement of the display area of the electronic whiteboard screen display interface;
an information acquisition and prediction module: the electronic whiteboard screen display interface detection method comprises the steps that if detected gesture information is gesture information for calling a display area of an electronic whiteboard screen display interface to move, the contact position and the sliding direction of a hand and a screen in the gesture information are obtained, and the display area to be moved and a target position of a user are predicted based on the contact position and the sliding direction of the hand and the screen;
a mobile switching module: and calling a corresponding system interface for the electronic whiteboard to switch the to-be-moved display area of the user to the target position.
9. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out a display area moving method according to any one of claims 1 to 7.
10. An electronic whiteboard, comprising:
one or more processors;
a memory;
one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, the one or more applications configured to: performing the display area movement method according to any one of claims 1 to 7.
