Abstract: A remote control device sends a patterned infrared signal to the display device. A display device receives the patterned infrared signal by using a plurality of infrared receivers. The display device obtains a projection pattern of the patterned infrared signal on a display screen. The display device determines a pointing position of the remote control device on the display screen based on the projection pattern. The display device displays a prompt mark in the pointing position of the display screen, where the prompt mark is used to prompt a user with the pointing position of the remote control device on the display screen.
