overlay and display a second image at a position corresponding to the first coordinate information on the first image displayed on the second touch screen when the first coordinate information is received,
transmit the received first coordinate information to the information terminal, and
display a notification, on the second touch screen, which indicates that the first touch screen is being operated in response to touch operations being performed at a plurality of points in the range in which the first image is displayed in the first touch screen.
2. The display control device according to claim 1 , wherein the second image is an image representing that the touch operation has been performed on the first touch screen.
3. The display control device according to claim 1 , wherein
the processor is further configured to
receive second coordinate information indicating a contact position on the first image from the second display device when the touch operation is performed in a range in which the first image is displayed in the second touch screen,
overlay and display the second image at a position corresponding to the second coordinate information on the first image displayed on the first touch screen when the second coordinate information is received, and
transmit the received second coordinate information to the information terminal.
4. The display control device according to claim 1 , wherein the display control device is connected to the information terminal via wireless communication and connected to the first display device and the second display device via wired communication.
5. The display control device according to claim 1 , wherein
the notification is a message, and
the processor is further configured to
accept no touch operation on the second touch screen when touch operations are performed at a plurality of points in the range in which the first image is displayed in the first touch screen, and
display the message on the second touch screen to indicate that the first touch screen is being operated when the touch operations are performed at the plurality of points in the range in which the first image is displayed in the first touch screen.
6. A display control method comprising:
receiving image information indicating a first image appearing on a display from an information terminal including the display;
controlling a first display device including a first touch screen and a second display device including a second touch screen based on the image information to display the first image on the first touch screen and the second touch screen;
receiving first coordinate information indicating a contact position on the first image from the first display device when a touch operation that brings a finger or an object into contact is performed in a range in which the first image is displayed in the first touch screen;
overlaying and displaying a second image at a position corresponding to the first coordinate information on the first image displayed on the second touch screen when the first coordinate information is received;
transmitting the received first coordinate information to the information terminal; and
displaying a notification, on the second touch screen, which indicates that the first touch screen is being operated in response to touch operations being performed at a plurality of points in the range in which the first image is displayed in the first touch screen.
7. A display control method according to claim 6 , wherein
the notification is a message, and
the display control method further comprises:
accepting no touch operation on the second touch screen when the touch operations are performed at the plurality of points in the range in which the first image is displayed in the first touch screen, and
displaying the message on the second touch screen to indicate that the first touch screen is being operated when the touch operations are performed at the plurality of points in the range in which the first image is displayed in the first touch screen.
8. A display control system comprising a first display device, a second display device, and a display control device,
the first display device including a first touch screen,
the second display device including a second touch screen,
the display control device including a memory and a processor, wherein
the processor is configured to
receive image information indicating a first image appearing on a display from an information terminal including the display,
control the first display device and the second display device based on the image information to display the first image on the first touch screen and the second touch screen,
receive first coordinate information indicating a contact position on the first image from the first display device when a touch operation that brings a finger or an object into contact is performed in a range in which the first image is displayed in the first touch screen,
overlay and display a second image at a position corresponding to the first coordinate information on the first image displayed on the second touch screen when the first coordinate information is received,
transmit the received first coordinate information to the information terminal, and
display a notification, on the second touch screen, which indicates that the first touch screen is being operated in response to touch operations being performed at a plurality of points in the range in which the first image is displayed in the first touch screen.
9. A display control system according to claim 8 , wherein
the notification is a message, and
the processor is further configured to
accept no touch operation on the second touch screen when the touch operations are performed at the plurality of points in the range in which the first image is displayed in the first touch screen, and
display the message on the second touch screen to indicate that the first touch screen is being operated when the touch operations are performed at the plurality of points in the range in which the first image is displayed in the first touch screen.
