A method for controlling an image display apparatus, the method comprising:

• generating motion information representing a motion of a user;
• transmitting the motion information to a server that combines motion information received from at least two image display apparatuses;
• receiving a signal including motion information representing a motion of a user of another image display apparatus other than the image display apparatus from the server;
• and
• displaying at least two viewpoint images of a 3D object corresponding to the user of the another image display apparatus based on the received signal with a background image.

An image display apparatus that displays a 3-dimensional (3D) image, the image display apparatus comprising:

• a camera module configured to capture an image of a first user of the image display apparatus;
• a network interface configured to transmit first user captured information representing the captured image of a first user of the image display apparatus to a server or another image display apparatus other than the image display apparatus, or receive second user captured information representing a captured image of a second user of the another image display apparatus from the server or the another image display apparatus;
• and
• a controller configured to control display of at least one of a 3D object corresponding to the at least one of the first user captured information and a 3D object corresponding to the second user captured information on the display with a background image.
