Abstract
In a method for controlling a projection screen using a projector device, the method builds a datasheet comprising a relationship between a mouse icon and a mouse operation, and triggers a camera to capture an image of the projection screen comprising a user interface projected from the electronic device onto the projection screen, and obtains the image of the projection screen from the camera. The image of the projection screen is used to obtain a position of the mouse icon in the image of the projection screen, and a mouse operation corresponding to the mouse icon is queried. The queried mouse operation is performed on the projector device according to the obtained position of the mouse icon, and an image of the queried mouse operation is projected from the projector device onto the projection screen.
