The user terminal 110 may be a wired communication terminal or a wireless communication terminal used by the user. The user terminal 110 may communicate with the server 120 through the network 130 using a communication module included in the user terminal 110. For example, when the user terminal 110 is a wireless communication terminal, the network 130 may be a wireless communication network using a base station and a gateway, or may be a wireless communication network for connecting to the Internet using an access point. . In addition, when the user terminal 110 is a wired communication terminal, the network 130 may be a wired communication network connected to the Internet using a local area network. Since such communication technology is well known, a detailed description thereof will be omitted.

The server 120 may be a system for providing an avatar service to the user terminal 110 in an avatar service or a chat service, a social network service (SNS), or a social network game (SNG). In the present embodiment, the server 120 may provide an avatar service to the user terminal 110. The avatar service according to the present embodiment may perform various actions for each layer used in the combination of avatars. It may mean a service for providing a. For example, the server 120 may be a system for providing a chatting service using an avatar to the user terminal 110. That is, the server 120 may provide an avatar capable of various movements to support the user to realistically express his or her emotions through the avatar.

2 is a view showing a database in an embodiment of the present invention. Here, the database 200 is proposed to enable various movements of the avatar, and as shown in FIG. 2, metadata 210, which is data about the movement of the avatar, and image data for each layer for configuring the avatar ( 220 may be stored and maintained respectively. In this case, the database 210 may be included in the server 120 or in a separate system for providing data to the server 120 in association with the server 120. In this case, the server 120 may extract necessary metadata 210 and image data 220 from the database 200 and provide the extracted metadata 210 and the image data 220 to the user terminal 110. In this case, the server 120 may synthesize the image data 220 for each frame based on the metadata 210 and provide the synthesized animation to the user terminal 110. In addition, the server 120 provides the extracted simply extracted metadata 210 and the image data 220 to the user terminal 110, and based on the metadata 210 in the user terminal 110, the image data ( 220 may be synthesized and displayed for each frame. That is, in the avatar service system and method according to the present embodiment, avatars of various movements may be expressed through a method of synthesizing the layer-specific image data 220 according to the metadata 210.

3 is an example for explaining image data for each layer in an embodiment of the present invention. That is, FIG. 3 illustrates an example in which a total of 360 rotating images may be generated from 1 ° to 360 ° in 1 ° increments based on the central axis 310 for one layer. If necessary, it is too natural that the rotation unit may be preset to another value (eg 2 ° or 5 °).

4 illustrates an example of layers constituting a body of an avatar for movement of an avatar according to an embodiment of the present invention. In Figure 4, the avatar's body is divided into ten layers: head, torso, upper right arm, lower right arm, upper left arm, lower left arm, upper right leg, lower right leg, upper left leg and lower left leg. An example comprised with these is shown. Here, each of the layers includes a central axis, and may rotate along the central axis. Of course, the avatar shown in FIG. 4 is only one example, and if necessary, the avatar may be configured with more layers to control more sophisticated motion.

5 illustrates an example of a process of extracting image data from a database according to an embodiment of the present invention. FIG. 5 shows that 360 rotation images for each layer are stored in a database as image data, and that rotation images necessary for representing a requested motion can be extracted and provided. First, in the database described in the example of FIG. 5, for each of the layers, a total of 360 rotating images are stored, from 1 ° to 360 °, in units of 1 °. In this case, “layer code” may mean an identifier for identifying each layer. That is, FIG. 7 illustrates rotation images of 59 ° to 64 ° among rotation images of the layer having the “layer code” of “bd_x_a1_01”, and 251 ° to 251 of rotation images of the layer having the “layer code” of “bd_x_a2_00”. An example of extracting rotated images up to °, and rotated images from 346 ° to 351 °, respectively, among the rotated images of the layer having the "layer code" of "bd_x_a5_00" is shown.

Each layer can not only rotate about the central axis according to the application of the rotating image, but also move the layers according to where the central axis is located on the screen. Information about the rotation of the central axis or the position of the central axis may be included in the metadata. For example, the metadata may include information (coordinates) of where the center axis of the rotated image having an angle (rotation value, angle) of each layer should be located on the screen.

6 illustrates an example of metadata in an embodiment of the present invention. First, in FIG. 6, "ani01.xml" may mean that metadata is provided in the form of an eXtensible MarkUp Language (XML) for the identifier "ani01" for the requested movement. Also, the value of "scene frame" may be an identifier for identifying a frame. That is, "scene frame = 1" may mean the first frame of the motion corresponding to "ani01". "layer code" may mean an identifier for identifying a layer, as described above. "z_order" may indicate the depth of layers in a frame. That is, as the value of "z_order" increases, this may mean that it is displayed on the front of the screen. "angle" may correspond to an identifier of the rotation image to be applied. That is, "angle = 0" may mean that a rotation image corresponding to 360 ° is applied. "offset_x" and "offset_y" may indicate coordinates. These coordinates may be absolute coordinates corresponding to the coordinates of the screen, or may be relative to the reference position of the area where the avatar is represented.
