The processor 110 renders the avatar of each user in the VR space so that the user can control the avatar using the VR machine 30 (S130).
The processor 110 renders game content selected by the user in a specific position in the VR space (S150).
The processor 110 provides a VR image so that the user can play the game in the VR space using the avatar (S170).
Referring to FIG. 3, it is illustrated that the VR content rendering device 100 renders three avatars in the VR space, and in FIG. 3, three different users enter the VR space.
The VR content rendering device 100 can ask the user to input user information containing the user's age and hobby, kinds of preferred games, kinds of preferred media contents, for instance, movies, animations, and the likes, and the processor 110 can analyze the user information and create and recommend an avatar matching the user.
In an embodiment, the VR content rendering device 100 can ask the user to select one among one or more user avatars stored in the database 130 or to create a new avatar.
The user may create a new avatar according to the user's taste or may edit and customize an avatar recommended by the VR content rendering device 100.
The VR content rendering device 100 provides an effect like the user actually plays game content together with the avatar while viewing the user's own avatar since rendering each avatar in the VR space and plays or uses game content using the avatar. Therefore, the avatar serves as a means to express the user.
The user inputs various control signals using the VR machine 30 in order to control the user's own avatar rendered in the VR space.
Furthermore, referring to FIG. 3, it is illustrated that the avatar 50 wears the VR machine 30 on the head. So, it provides an effect like many friends play a game in one space wearing the VR machines 30.
In an embodiment, the VR content rendering device 100 recognizes a model name of the VR machine 30 which the user wears actually, loads an image of the VR machine 30 of the corresponding model, and renders the loaded image to the avatar in order to increase reality.
In an embodiment, the processor 110 renders game content 71 selected by the user in a specific position in the VR space, and provides, outputs and controls a VR image to the user's VR machine 30 so that the user can play the game 71.
In this instance, the processor 110 determines a rendering position in the VR space of the game content 71 based on the structure and background of the VR space and the position of at least one avatar existing in the VR space, and renders the game content 71 at the determined position.
The processor 110 can render the VR image and provide the VR image to the VR machine 30 so that the game content in the VR image output to the VR machine 30 is viewed from a bird's eye view perspective.
However, the present disclosure is not fixed to the bird's eye view perspective, and the processor 110 can provide various perspectives.
In an embodiment, the processor 110 can render such that the game content in the VR image output to the VR machine 30 is output at an angle that the avatar in the VR space views the game content.
Therefore, the user can control the avatar to control the point of view to view the game content, and can feel reality that the point of view is reflected to the VR image.
In detail, FIG. 3 illustrates that a state in which three users enter the VR space and three avatars are rendered in the VR space is viewed from three perspectives, and actually, the VR image corresponding to the avatars' perspectives is output to the VR machine.
As illustrated in FIG. 3, the VR content rendering device 100 allows a plurality of users to enter the VR space, and renders game content selected by a specific user.
Therefore, not only the user who selected the game content but also other users in the VR space can play the corresponding game content together using their own avatars.
Moreover, the users can play the game together or can select a watching mode.
In this instance, in the case that a plurality of users play the game together, the processor 110 can render and provide VR images by each user such that perspectives of rendered contents shown through the avatar of each user are viewed according to perspective settings of each user.
However, the present disclosure is not limited thereto, and the processor 110 can basically render the VR image in consideration of an angle that the avatar of each user views the game content in the VR space, and provide the VR image to the VR machine 30 of each user.
In an embodiment, the database 130 stores an image of a game control means specific to at least one game content.
For instance, the game control means may be a game controller including a joystick and buttons, a game controller including a steering wheel for racing games, or a game controller including a racket for a tennis game.

In detail, the processor 110 can render the avatar's motions to control the game control means according to the control signals input to the VR machine 30 by the user.
For instance, when the user selects a tennis game content, the VR image is rendered like the avatar uses a tennis racket. When the user inputs a control signal to swing a racket to the VR machine 30, a VR image that the avatar swings the tennis racket corresponding to the control signal is rendered.
Technical Features to Determine Rendering Position of Game Content
Referring to FIG. 3, it is illustrated that a rendering space 70 is rendered in front of avatars 50, game content 71 is rendered in the rendering space 70, and characters 75 played by users are rendered in the game content 71.
As described above, the processor 110 determines the rendering position in the VR space of the game content 71 based on the structure and background of the VR space and the position of the avatars 50 existing in the VR space.
Referring to FIG. 3, the processor 110 renders at least one rendering space 70 to render the game content 71 at the determined rendering position.
In this instance, the rendering space 70 means a space or an area of a predetermined size to render the game content 71 in the VR space.
In an embodiment, as illustrated in FIG. 3, the processor 110 can render the rendering space 70 like a virtual table.
As described above, the processor 110 can render the rendering space 70 having specific shape and size in order to render the game content 71.
In addition, the processor 110 renders the game content in at least a part/area of the rendered rendering space 70.
In an embodiment, the processor 110 can determine a size and a rendering position of the rendering space 70 in the VR space, on the basis of the number of the at least one user entering the VR space and the number of game contents 71 selected by the users entering the VR space.
For instance, if more users enter the VR space, the processor 110 can set the rendering space 70 to be wider.
For example, the processor 110 can set the rendering space 70 to be wider if the game content 71 selected by the user is a game to indicate a wide area in a game.
The processor 110 can determine a shape of the rendering space 70 to render the selected game content, on the basis of game environment information of the game content selected by the user.
In this instance, the game environment information may mean a map of the game content.
In an embodiment, the processor 110 can render the game content in at least a part/area of the rendering space 70, and can process awkwardness of a cross section cut off from a boundary surface of the content rendering space if the game content is game content having a seamless world.
The processor 110 can render the background image selected by the user, entering the VR space, as the background for the VR space.
However, the present disclosure is not limited thereto, the processor 110 can render the background image in the VR space when receiving a request for rendering a background image from the user, and does not render the background if the user does not want to render the background image.
In an embodiment, the processor 110 loads a background image for rendering the background of the VR space, on the basis of at least one among an age, a hobby, at least one preferred media content, for instance, a movie, an animation, and the like, and game content selected by each user, and a preferred place of each user entering the VR space.
Moreover, the processor 110 renders the loaded background image as the background of the VR space.
FIG. 4 illustrates that the Eiffel Tower in Paris is rendered as a background image of the VR space.
The processor 110 can select such a background image and render the background image to the VR space if the game selected and played by the user is set in France as a background or if users prefer movies set in France.
FIG. 5 illustrates that a Pororo image is rendered as a background image of the VR space.
The processor 110 can select such a background image and render the background image to the VR space if users are in a low age range, for instance, children, or if users select Pororo as a preferred animation.
FIG. 6 illustrates that the Status of Liberty or a work of art is rendered as a background image of the VR space.
The processor 110 can select such a background image and render the background image to the VR space if users prefer New York or media content, such as a work of art.
In an embodiment, the processor 110 can collect state information of the character 75 in the game content selected by the user entering the VR space in real time.
Furthermore, if the processor 110 detects a change above a reference value from the state information, based on the detection result, the processor 110 can render special effects matching the detection result in at least a part of an area in the VR space.
In this instance, the state information may be any information related to the character's conditions, activities and the like, and may be varied according to kinds of game contents.
For instance, in the case of an RPG game content, the state information of the character 75 may be the character's physical strength, survival, level, and the like.
For instance, in the case of sports game content, the state information of the character 75 may be the character's physical strength, damage, score, and the like.
As described above, if singularity in the state information of the character 75 in the game content that the user is playing is detected, the VR content rendering device 100 can provide special effects matching the detection results in the VR space, so that the users entering the VR space can appreciate the special effects using their own avatars.
In an embodiment, the processor 110 supports such that a first user can view second game content 72 while playing first game content 71.
In the situation in which the first user participates in a plurality of the game contents, if the first game content is a turn-based game and a first avatar's perspective at the first user's turn is in the direction of the second game content, the processor 110 performs conditions set by the first user.
In this instance, the conditions include a first condition to forcibly convert the first avatar's perspective to the first game content, a second condition to convert a turn alarm object to the second game content, and a third condition to provide a sound alarm to the VR machine 30 which the first user is wearing.
If the first user sets the first condition, the processor 110 forcibly converts the first avatar's perspective directing another game content, for instance, the second game content, to the first game content.
Therefore, the VR image in the VR machine 30 of the first user is converted from the second game content to the first game content in a moment.
Therefore, the first user can play a plurality of different game contents on VR at the same time.
Referring to FIG. 7, the VR content rendering device 100 can render and provide the plurality of different game contents in the VR space.
In detail, if the user selects the plurality of different game contents, the processor 110 can partition an area on the rendered rendering space 70 and render each of the selected game contents in each partitioned area.
Therefore, the VR content rendering device 100 can provide a plurality of different game contents on one VR space.
In an embodiment, when a plurality of users enter the VR space and another user (second user) selects game content (second game content) 72 different from the game content (first game content) 71 selected by the first user, the processor 110 partitions an area on the rendered rendering space 70 and respectively renders the first game content 71 and the second game content 72 in the partitioned areas.
Therefore, the plurality of users entering the VR space provided by the VR content rendering device 100 can select and play different game contents, and can watch or play a game that another user is playing.
In an embodiment, when an environment setting function of the game content is performed by the user's VR machine 30, as illustrated by the left avatar of FIG. 3, an UI for environment setting is rendered at the upper part of the corresponding game content, and the user controls the user's own avatar to perform the environment setting of the game content.
Therefore, the present disclosure can support such that the user can perform various settings of the game content in the VR space.
According to the present disclosure, the VR content rendering device providing bird's eye view perspectives can be provided.
Additionally, the present disclosure can provide a VR content of a 3D VR hologram type.
