1 is a diagram for explaining a content reproduction system according to an embodiment.

Referring to FIG. 1 , a content reproduction system 100 according to an embodiment includes a terminal 110 , a service server 120 , and a content server 130 . Since the content reproduction system 100 may reproduce augmented reality content, it may be expressed differently as an augmented reality content reproduction system.

The terminal 110 may correspond to a mobile terminal (eg, a smart phone, a tablet PC, etc.).

The terminal 110 may execute an application for realizing augmented reality.

The user may select one of several augmented reality contents (eg, augmented reality characters) in the terminal 110 .

The terminal 110 may arrange the augmented reality content selected by the user on a space photographed through the camera, and when the augmented reality content is arranged, information for reproducing the augmented reality content may be obtained. The information for the reproduction of the augmented reality content may include, for example, at least one of identification information of the augmented reality content, spatial recognition information, object recognition information, an arrangement position of the augmented reality content, and a viewing angle of the user. not limited Information for the reproduction of augmented reality content will be described in detail with reference to FIG. 2 . The terminal 110 transmits information for the reproduction of the augmented reality content to the service server 120 .

When the service server 120 receives the information for the reproduction of the augmented reality content from the terminal 110 , the service server 120 may transmit identification information of the augmented reality content to the content server 130 .

The content server 130 may store a content asset of each of several augmented reality content. Also, the content server 130 may store a speed value (or a time value) for each action. Actions may include, but are not limited to, running, jumping, and the like, for example. As an example, the content server 130 may store "a speed value of 1 cm/s of a running action (or a time value of 5 seconds of a running action)". The jumping action may include a jumping action and an aerial action, and the content server 130 may store "a speed value of the jumping action of 1 cm/s" and "a speed value of the aerial action of 1 cm/s".

The content server 130 may transmit a content asset corresponding to the identification information received from the service server 120 to the service server 120 . Also, the content server 130 may transmit a speed value (or time value) for each action to the service server 120 .

The service server 120 may determine the content reproduction information based on the information received from the terminal 110 and the speed value for each action received from the content server 130 . This will be described in detail with reference to FIG. 2 .

The service server 120 may transmit content reproduction information to the terminal 110 .

The terminal 110 may reproduce the augmented reality content based on the content reproduction information. Existing augmented reality content can be played on the screen without space and reality recognition. For example, suppose that the existing augmented reality character's running animation is 5 seconds and there is an obstacle in the augmented reality space. In this case, the augmented reality character can only perform a running motion for 5 seconds. However, according to an embodiment, the augmented reality character may be reproduced according to the space being photographed through the camera. Accordingly, according to an embodiment, the augmented reality character may perform a running motion to the front of the obstacle and then may perform an operation to jump over the obstacle.

2 is a flowchart illustrating an operation of a content reproduction system according to an exemplary embodiment.

Referring to FIG. 2 , the terminal 110 may select one of several augmented reality contents according to a user's selection input ( 210 ). In this case, the terminal 110 may obtain identification information of the selected augmented reality content.

The terminal 110 may arrange the selected augmented reality content ( 211 ). For example, the terminal 110 may recognize the floor through the camera, and after recognizing the floor, the selected augmented reality content may be disposed on the augmented reality space. If the step 211 is expressed differently, the user may select a location where the augmented reality content is to be placed on the augmented reality space, and through this selection, the terminal 110 detects the location where the user wants to place the augmented reality content. can

When the selected augmented reality content is arranged, the terminal 110 may acquire information for playing the selected augmented reality content ( 212 ). As an example, when the selected augmented reality content is arranged, the terminal 110 includes spatial recognition information for recognizing a space photographed through a camera, object recognition information for recognizing an object in the corresponding space, an arrangement position of the selected augmented reality content, and At least one of the viewing angles of the user may be acquired. The object recognition information may include, for example, whether there is an object in space and the size of the object, and the spatial recognition information may include, for example, information on the floor, the distance between the selected augmented reality content and the object. may include For example, the terminal 110 may measure the distance between the object and the arrangement position of the selected augmented reality content by performing spatial recognition. The viewing angle is a user's camera angle or an angle at which the camera of the terminal 110 is inclined, for example, the terminal 110 may obtain the user's viewing angle through a gyro sensor or a geomagnetic sensor.

The terminal 110 may transmit information for playing the selected augmented reality content to the service server 120 ( 213 ). As an example, the terminal 110 transmits at least one of identification information of the selected augmented reality content, spatial recognition information, object recognition information, an arrangement position of the selected augmented reality content, and a user's viewing angle (or camera angle) to the service server 120 . ) can be transmitted.

When the service server 120 receives the information for playing the selected augmented reality content from the terminal 110 , the service server 120 may transmit identification information of the selected augmented reality content to the content server 130 ( 214 ).

When the identification information of the selected augmented reality content is received from the service server 120 , the content server 130 may transmit the content asset of the corresponding identification information and the speed value for each action to the service server 120 ( 215 ). For example, when identification information of the selected augmented reality content is “ID_A”, the content server 130 may transmit a content asset corresponding to “ID_A” to the service server 120 . Also, the content server 130 may transmit a speed value for each action mapped to “ID_A” to the service server 120 . If the speed value of the running action and the speed value of the jumping action are mapped to "ID_A", the content server 130 may transmit the speed value of the running action and the speed value of the jumping action to the service server 120 . The speed value of the jumping action may include, for example, a speed value of the jumping action and a speed value of the aerial action.

The service server 120 may determine content reproduction information ( 216 ). In one embodiment, the service server 120 may check the size of the object through the object recognition information received from the terminal 110 and the object in space and the selected augmented reality through the spatial recognition information received from the terminal 110 . You can check the distance between the contents. The service server 120 may calculate the size value of the augmented reality content and the time value of the animation so that the selected augmented reality content performs an action that is not disturbed by the recognized object or performs an action using the object.

As an example, each of the horizontal length, vertical length, and height of the augmented reality character selected by the user is 1 cm, and the speed value of the running action of the augmented reality character, the speed value of the jumping motion of the augmented reality character, and the corresponding augmented reality Let's assume that each speed value of the character's air movement is 1 cm/s. Also, suppose that the terminal 110 recognizes the height of the cup positioned in space as 1 cm and the distance between the cup and the augmented reality character as 30 cm. The service server 120 may calculate a size value for adjusting the size of the selected augmented reality character in consideration of the height of the cup. In the example described above, since the height of the cup and the height of the selected augmented reality character are the same, the service server 120 may calculate the size value of the selected augmented reality character as 1. In other words, the service server 120 may decide to keep the size of the selected augmented reality character. Depending on the implementation, the service server 120 may increase or decrease the size value in consideration of the user's viewing angle. If the height of the cup is 1.5 cm, the service server 120 may calculate a size value for adjusting the size of the selected augmented reality character as 1.5. In other words, the service server 120 may calculate the size value so that the size (or height) of the selected augmented reality character is 1.5 times. Since the distance between the selected augmented reality character and the cup is 30 cm and the speed value of the running action of the selected augmented reality character is 1 cm/s, the service server 120 may calculate the running animation of the selected augmented reality character as 30 seconds. In addition, the service server 120 may calculate each of the animation of the jumping motion and the animation of the aerial motion of the selected augmented reality character as 1 second. Depending on the implementation, the service server 120 may increase or decrease the time value of the animation in consideration of the user's viewing angle.

The service server 120 may transmit the determined content reproduction information to the terminal 110 ( 217 ). For example, the service server 120 may transmit the size value of the selected augmented reality content and the time value of the animation of the selected augmented reality content to the terminal 110 . In the example described above, the service server 120 determines the size value of the selected augmented reality character of 1, the running animation time value of 30 seconds, the jumping motion animation time value of 1 second, and the aerial motion animation time value of 1 second. It can be transmitted to the terminal 110 .

The terminal 110 may reproduce the selected augmented reality content by reflecting the content reproduction information received from the service server 120 . In the example described above, the terminal 110 may play the augmented reality character running to the cup for 30 seconds in the augmented reality space, and may play the augmented reality content to jump over the cup. Accordingly, augmented reality content may be reproduced according to reality recognition.

According to an embodiment, the above-described selected augmented reality content may be stored in the terminal 110 or transmitted from the service server 120 to the terminal 110 when the terminal 110 requests the service server 120 . In the case where the selected augmented reality content is stored in the terminal 110 , the terminal 110 may reproduce the corresponding augmented reality content by receiving the size value of the augmented reality content and the time value of the animation from the service server 120 . In another implementation, the terminal 110 may reproduce the corresponding augmented reality content by receiving the selected augmented reality content, the size value of the selected augmented reality content, and the time value of the animation of the selected augmented reality content from the service server 120 . .

The controller 320 may place content (eg, augmented reality content) on an augmented reality space (or a space captured through the camera 310 ). In other words, the controller 320 may detect a location where the user intends to place the content on the augmented reality space.

When the content is arranged, the controller 320 acquires information for content reproduction. Information for content reproduction includes, for example, identification information of the corresponding content, space recognition information that the controller 320 recognizes a space photographed through the camera 310, and information that the controller 320 recognizes an object in space. It may include at least one of object recognition information, a content arrangement position, and a user's viewing angle.

The controller 320 transmits the obtained information to the service server 120 through the communication unit 330 .
