Abstract

The present invention provides a method for adjusting the window size of a touch-controlled large screen. The method includes: S1: the user touches the large screen to make a gesture operation; S2: the sensor collects the image information of the large screen and sends it to the computer; S3: the computer uses the gesture The recognition algorithm judges the gesture type, calls out the screen information corresponding to the gesture type and sends it to the controller; S4: the controller sends the received screen information and the layout information of the screen on the large screen to the large screen; S5: the large screen The screen displays the picture information received from the computer to realize the adjustment of the size of the window. The method for adjusting the window size of the large touch screen provided by the present invention solves the problem of difficult operation of the window on the large screen, and effectively improves the accuracy and convenience of the touch operation of the large touch screen.
