Hereinafter, operations of the server 110, the manager terminal 120, and the user terminal 130 will be described in more detail.

The manager terminal 120 may obtain attributes of the virtual space based on the manager's input. The attribute of virtual space is necessary to create virtual space, and is selected from information about the type of virtual space, size information of virtual space, location information of real space corresponding to virtual space, time information of virtual space, and shape of virtual space. may contain at least one.

The virtual space type information may be related to the purpose of the virtual space. The virtual space type information may include at least one of an exhibition hall, an art gallery, an apartment, a temple, and a church.

The size information of the virtual space may represent the area of the ground surface of the virtual space. Size information of the virtual space may be represented by the number of pixels (voxels). For example, the size information of the virtual space may include the number of pixels included in the horizontal side and the number of pixels included in the vertical side. In addition, the size information of the virtual space may be expressed as an area of a real space, and the unit may be a square meter or a weekday.

The server 110 or the user terminal 130 may store information on topography or features corresponding to the location information of the above real space in advance.

Time information of virtual space may represent virtual time. The virtual time may include at least one of a date, day, hour, minute, or second. Based on the virtual time, the server 110 or the user terminal 130 determines the position of the sun, the position of the moon, whether street lights are turned on, whether the headlights of the car are turned on, whether lights in the virtual space and surroundings of the virtual space are turned on. can decide As such, since the virtual space and light around the virtual space are automatically controlled based on the time information of the virtual space, the user can feel the virtual space as a real space using the user terminal. Time information of the virtual space may be the same as the current time. But not limited to this. Time information of the virtual space may be determined based on location information of a real space corresponding to the virtual space. That is, the server 110 may determine the time zone corresponding to the location information of the virtual space as the time information of the virtual space. The server 110 may determine the time information of the virtual space differently from the actual time based on the input of the manager terminal 120 or the user terminal 130 .

The shape of the virtual space may be a three-dimensional polyhedral shape. The shape of the virtual space may be, for example, a rectangular parallelepiped. However, it is not limited thereto, and when the type information of the virtual space is an apartment, it may have a complex polyhedral shape because it includes a plurality of rooms, a living room, and a kitchen.

A process in which the manager terminal 120 acquires the properties of the virtual space will be described in detail later.

The server 110 may perform step 311 of obtaining attributes of the virtual space including time information of the virtual space and location information of the real space from the manager terminal 120 . Since the time information of the virtual space and the location information of the real space have been previously described above, a detailed description thereof will be omitted. The attributes of the virtual space may include information for the server 110 to create a skeleton of the virtual space.

The server 110 may perform step 321 of generating information on the 3D virtual space based on the attributes of the virtual space. The server 110 may acquire shapes of a plurality of candidate virtual spaces stored in advance based on information on types of virtual spaces from a memory. Also, the server 110 may obtain a plurality of candidate virtual objects that may be disposed in the virtual space based on the type information of the virtual space. The server 110 determines the shape of one virtual space among the shapes of a plurality of candidate virtual spaces based on the signal from the manager terminal 120, and determines a virtual object to be placed in the virtual space among the plurality of candidate virtual objects. can

The server 110 may retrieve a 3D map corresponding to location information in real space from a pre-stored 3D map. Here, the 3D map may refer to a map in which topography and features are displayed in 3D. The 3D map may be provided by national organizations or local governments. For example, the 3D map may be the same as the 3D map provided by the Seoul Metropolitan Government.

The server 110 may determine the shape of the virtual space based on the shape of the virtual space included in the attributes of the virtual space. The virtual space may have a polyhedral shape.

The server 110 may determine the shape of the virtual space based on the size information of the virtual space. For example, when the shape of the virtual space is determined to be a rectangular parallelepiped, the server 110 may automatically determine the shape of the virtual space based on size information of the virtual space. Size information of the virtual space may include a horizontal width, a vertical width, and a height.

As already described, the location information in real space may be 3D coordinate information. That is, the location in real space may include height information as well as location information on the ground. The server 110 may arrange a polyhedron-shaped virtual space at a location corresponding to the location information of the real space on the 3D map.

In addition, the server 110 may determine the position of the sun, the position of the moon, whether a street light is turned on, whether the headlights of a car are turned on, and whether lights in the virtual space and surroundings of the virtual space are turned on based on the time information of the virtual space. . For example, when the time information of the virtual space is low, objects capable of emitting light may not light up. Also, when the time information of the virtual space is night, objects capable of emitting light may not be lit. An object capable of emitting light may be the sun, the moon, an indoor light, a street lamp, or an automobile.

The server 110 may arrange basic virtual objects around the virtual space without receiving a manager's input from the manager terminal 120 . The basic virtual object may be arranged outside the virtual space to form an atmosphere of the virtual space and implement hyper reality. For example, it may include a tree, sun, moon, street light, tree, grass, terrain, structure (building), or car outside the virtual space. The server 110 may store pre-examined data for each location in the real space. The server 110 may automatically arrange basic virtual objects around the virtual space based on the location of the real space. The pre-examined data may be generated by applying an object recognition program to a street view image. Based on the manager's input received from the manager terminal 120, the server 110 may modify the location, type, or number of the basic virtual object.

Also, the server 110 may adjust the number of vehicles on the road based on time information of the virtual space. For example, the server 110 may receive traffic information from an external server. The server 110 may receive information on traffic volume according to day of the week, road, and time. The server 110 may store the traffic volume for a predetermined time. Here, the predetermined time may be 4 weeks or more and 52 weeks or less. In addition, the server 110 may obtain an average traffic volume based on the traffic volume obtained for a predetermined period of time. The server 110 may obtain the average traffic volume of roads around the location of the real space corresponding to the virtual space based on the time information of the virtual space. Here, the time information of the virtual space may be related to the day of the week or time. In addition, the server 110 may determine the number of vehicles, which are virtual objects, corresponding to the average traffic volume of surrounding roads. The server 110 may store in advance a table in which average traffic volume corresponds to the number of vehicles. In addition, the server 110 may control the user terminal 130 to display as many vehicles as the determined number of vehicles on the road. The user terminal 130 may generate noise based on the determined number of vehicles. That is, as the determined number of vehicles increases, noise may increase. Users can experience the level of noise in a virtual space without going to the actual space. Also, when the time is night, the server 110 may cause vehicles to turn on their headlights. Therefore, the user can experience light pollution based on the headlights of the vehicle displayed on the user terminal 130 or enjoy the mood of the night in the real space in advance in the virtual space.

The server 110 may perform step 322 of acquiring properties of the virtual object. Here, the virtual object may refer to a virtual object disposed inside or outside the virtual space. The attribute of the virtual object may include at least one of object identification information, type, texture, color, shape, size, and location. Types of virtual objects may include backgrounds (trees, grass, flower beds, artifacts), buildings (walls, stairs, windows, doors), furniture, cars, and the like. Virtual objects may include basic virtual objects. Each virtual object may include identification information. The server 110, the manager terminal 120, and the user terminal 130 may specify a virtual object based on identification information of the virtual object. The server 110 may store the 3D model and color of the virtual object. The description of properties of virtual objects may be applied to properties of virtual items. If virtual objects are used to decorate a virtual space, virtual items can be used to decorate virtual characters.

The server 110 may previously store texture information included in the attributes of the virtual object. That is, the server 110 may previously store information on a plurality of textures applicable to virtual objects as a texture database. Texture information may include at least one of 2D information, 3D information, pattern, or color of the surface of the virtual object. For example, even if it is the same wall, if the type of wallpaper is changed, the texture may be different. Similarly, the server 110 may differently set the feel of the surface of the virtual object based on texture information. Texture information can only express information about a unit area. In order to cover an area larger than the unit area of the virtual object, the server 110 may repeatedly reflect texture information on the surface of the virtual object.

Texture information may be 2-dimensional information, but is not limited thereto and may have a 3-dimensional form. When texture information is 3D information, hyper reality can be more easily implemented. For example, texture information on an inner wall, which is a virtual object, may be a pattern or color expressed in 2D information. In the real world, since most interior walls are finished with 2D wallpaper, texture information on the interior walls may be sufficient as a pattern or color expressed on a 2D surface. However, in the case of an outer wall in the real world, bricks and joints between bricks may be included, and there may be three-dimensional curves. In order to implement such a 3D texture in a virtual space, texture information according to the present disclosure may include a 3D shape. Texture information may be information representing a relief shape. That is, a portion exposed to the outside in the virtual space is implemented in 3D, but a portion not exposed to the outside may be flat or not implemented. The 3D texture information may include surface information having a curve with respect to a flat reference plane, and patterns and colors expressed on the surface. The reference plane may be a surface in contact with a virtual object in the virtual space, and the surface information may be a surface opposite to the reference plane, which is visible to the user in the virtual space. The surface information may be a set of points having different distances from the reference plane.

The server 110 may include at least one piece of 3D texture information to represent the outer surface of the virtual object. In addition, the server 110 may repeatedly apply 3D texture information for a unit area to the surface of the virtual object to configure the surface of the virtual object with a large area. A unit area may be a square. The distance of the edge of the surface information included in the texture information of unit area to the reference plane may be constant. Therefore, even if texture information of a plurality of unit areas is combined, a feeling of being connected may occur. However, it is not limited thereto.

The server 110 may set initial texture information for the virtual object. The server 110 may change texture information reflected in the virtual object based on a signal from the manager terminal 120 or the user terminal 130 . More specifically, the server 110 may receive a texture identifier for a virtual object from the manager terminal 120 or the user terminal 130 . The server 110 may reflect texture information corresponding to the received texture identifier to the virtual object. Even objects having the same shape may provide users with a feeling of different virtual objects by applying different texture information. For example, when a virtual space is implemented by applying different texture information to a wall, a user may experience different feelings from the virtual space. According to the present disclosure, a user can easily change intuition information applied to a virtual space by using information on a plurality of textures stored in a texture database, and can implement a virtual space closer to a real space. In addition, when using different textured finishes in a real space, the user can feel the atmosphere emitted by the space in advance in the virtual space.

Texture information may be classified according to the type of virtual object. The user terminal 130 or the manager terminal 120 may first select the type of virtual object. The user terminal 130 or the manager terminal 120 may display a plurality of pieces of texture information corresponding to the type of the selected virtual object. The user terminal 130 or the manager terminal 120 may select one piece of texture information from among a plurality of pieces of output texture information based on a user's or manager's input.

The server 110 may receive attributes of virtual objects from the manager terminal 120 or the user terminal 130 . The server 110 may arrange a virtual object in the virtual space based on the attribute of the virtual object received from the manager terminal 120 or the user terminal 130 . That is, the server 110 may arrange a virtual object selected from among a plurality of previously stored candidate virtual objects based on the attribute of the virtual object from the manager terminal 120 or the user terminal 130 in the virtual space. Also, the attribute of the virtual object may be input by a manager or a user, or may be automatically generated by the manager terminal 120 or the user terminal 130 . The server 110 may modify the color, shape, and size of the 3D model of the virtual object based on the attributes of the virtual object received from the manager terminal 120 or the user terminal 130 .

Positional information included in the attributes of the virtual object may mean the position of the virtual object in the virtual space. Location information included in the properties of the virtual object may be expressed in a 3D coordinate system. The location information included in the attributes of the virtual object may include orientation information of the virtual object. The orientation information may include an arrangement direction and rotation degree of virtual objects in the virtual space. Arrangement direction and degree of rotation can also be expressed in a three-dimensional coordinate system.

The server 110 may perform step 323 of including the attribute of the virtual object in the information about the 3D virtual space. That is, the server 110 may merge and store the attributes of virtual objects disposed in the virtual space with information about the virtual space. Information on the 3D virtual space may include attributes of the virtual space and attributes of the virtual object. Accordingly, when the server 110 transmits only information about the virtual space to the user terminal 130, the user terminal 130 can display the virtual space and virtual objects implemented in the server 110 on the display.

The server 110 may perform step 324 of transmitting information about the 3D virtual space to the user terminal 130 . The server 110 may transmit some of the information on the 3D virtual space to the user terminal 130 . For example, the server 110 may transmit only information necessary for the user terminal 130 to display virtual space and virtual objects. The user terminal 130 may receive information about a 3D virtual space. The user terminal 130 may display virtual space and virtual objects on a display based on information about the 3D virtual space.

The user terminal 130 may perform step 331 of acquiring information about the virtual person. The user terminal 130 may acquire information about the virtual person from the memory of the user terminal 130 or may receive it from the server 110 .

The information on the virtual character may include rendering information about the appearance of the virtual character. The appearance of the virtual character may include a skin color, a body type model, and a face model of the virtual character. The body type model may include a child type, a youth type, an adult type, and an elderly type. The body shape model may include height information. The model of the face may be the position of the eyes, the distance between the eyes, the size of the eyes, the shape of the eyes, the color of the eyes, the position of the nose, the shape of the nose, the height of the nose, the position of the mouth, the shape of the mouth, the hair style, or hair color, etc.

The information about the virtual person may include information about the possessed item (item). Possessed items may include clothes, accessories, and bags worn by the virtual character. Information about the virtual character may include at least one of identification information of clothes and color of clothes. Identification information of clothes may vary according to the shape of the clothes. The information about the virtual person may include at least one of accessory identification information, accessory color, bag identification information, and bag color. The user terminal 130 may display a virtual person in a virtual space based on information about the virtual person. In the present disclosure, items are used to decorate virtual characters, and objects are used to decorate virtual spaces.

The user terminal 130 may perform step 332 of displaying at least one of a virtual person, a virtual space, and a virtual object on a display based on the information on the 3D virtual space and the information on the virtual person. When the user terminal 130 implements the virtual space as a first-person view, virtual characters may not be displayed on the display. The user may experience the virtual space from a first-person perspective through the user terminal 130 . When the user terminal 130 implements the virtual space as a third-person view, the virtual person may be displayed on the display. Users can feel the atmosphere created by the virtual space while experiencing their virtual character in the virtual space. Virtual characters of a plurality of users may be active in the virtual space. However, it is not limited thereto, and only one user's virtual character can be active in the virtual space.

Hereinafter, step 332 of displaying virtual characters, virtual spaces, and virtual objects on the display by the user terminal 130 together with FIG. 9 will be described in more detail.

Referring to FIG. 9 , the user terminal 130 may further perform the following process to perform step 332 of displaying a virtual person, a virtual space, and a virtual object on a display. The user terminal 130 may perform step 910 of locating the virtual space on a part of the pre-stored 3D map based on the location information of the space included in the information on the 3D virtual space. That is, in the same way that the server 110 arranges the virtual space at a location corresponding to the location information of the real space on the 3D map, the user terminal 130 has a location corresponding to the location information of the space among the pre-stored 3D maps. A virtual space can be placed in a location. The 3D map used by the server 110 may be the same as the 3D map used by the user terminal 130 . The user terminal 130 may receive and store the 3D map from the server 110 in advance.

Just as the server 110 arranges the basic virtual objects around the virtual space, the user terminal 130 may arrange the basic virtual objects in the virtual space. As already described, the basic virtual object may be arranged outside the virtual space to form an atmosphere of the virtual space and implement hyper reality. For example, it may include a tree, sun, moon, street light, tree, grass, terrain, structure (building), or car outside the virtual space. The server 110 may store pre-surveyed data for each location in the real space, and the pre-surveyed data may be transmitted to the user terminal 130 . The user terminal 130 may automatically arrange basic virtual objects around the virtual space based on the location of the real space and pre-surveyed data received from the server. Also, the user terminal 130 may modify the location, type, or number of the basic virtual object based on the user's input. The spatial location information may be 3D location information. That is, it may include values for three axes. Also, location information of a space used by the user terminal 130 may correspond to location information of a real space. The process of determining the number of vehicles around the virtual space by the server 110 has already been described, and the user terminal 130 can also perform the same process.

The user terminal 130 may perform step 920 of determining the direction and intensity of light in the virtual space based on the time information of the virtual space included in the information about the 3D virtual space. For example, the user terminal 130 may determine the position of the sun and the position of the moon based on time information of the virtual space. It can also determine the size of the moon. Here, the sun and moon in virtual space may be included in basic virtual objects. The user terminal 130 may render the direction and intensity of light in the virtual space using at least one of the position of the sun, the position of the moon, and the size of the moon. As such, since the direction and intensity of light are determined similarly to reality, the user can feel hyper reality in the virtual space.

The user terminal 130 may perform step 930 of arranging at least one virtual object in the virtual space based on the attribute of the virtual object included in the information about the 3D virtual space. Positional information included in the attributes of the virtual object may mean the position of the virtual object in the virtual space. Location information included in the properties of the virtual object may be expressed in a 3D coordinate system. The location information included in the attributes of the virtual object may include orientation information of the virtual object. The orientation information may include an arrangement direction and rotation degree of virtual objects in the virtual space. Arrangement direction and degree of rotation can also be expressed in a three-dimensional coordinate system.

The user can experience a hyper-reality virtual space that embodies a real space by using the user terminal 130 . Since the virtual space is implemented at a virtual location corresponding to the location of the real space, the user can experience the real space in advance. For example, objects placed in the virtual space may be past objects in the real space. Therefore, the user can experience the past of the real space in the virtual space. In addition, objects arranged in the virtual space may be future expected objects in the real space. Therefore, the user can experience the future of the real space in the virtual space. For example, the server 110 may store attributes of virtual objects respectively corresponding to a plurality of time zones. Also, when obtaining date information or time period information from the user terminal 130, the server 110 may obtain attributes of a virtual object corresponding to the corresponding date information or time period information. Also, the server 110 may arrange virtual objects in the virtual space based on the acquired attributes of the virtual objects. Therefore, the user can easily experience the change of space according to time.

The user terminal 130 may perform step 410 of controlling the virtual character to move in the virtual space and interact with the virtual object based on the user's input. The virtual character may have a predetermined interaction with the virtual object. The predetermined interaction may transform a posture of a virtual character or a position, color, or shape of a virtual object. For example, if the virtual object is a chair, the virtual character can interact to sit on the virtual object. The virtual character may perform a sitting motion on the virtual object. Also, if the virtual object is a light, the virtual character can take an action to turn on or turn off the light. The virtual object may be turned on or off in response to the motion of the virtual character. If the virtual object is a seesaw, the virtual character can interact to sit on the virtual object, and the seesaw, which is a virtual object, can move in response to the motion of the virtual character sitting down.

The user terminal 130 records the location of the virtual character in the virtual space, the time the virtual character stayed at the location in the virtual space, the virtual object displayed on the display of the user terminal at the location of the virtual character, and details of interaction with the virtual object. Step 420 of acquiring log information including the log information may be performed.

The position of the virtual character in the virtual space may be represented by 3D coordinates. The user terminal 130 may obtain the position of the virtual person at a predetermined period. The predetermined period may be 5 seconds, 10 seconds or 1 minute, or 10 minutes or the like.

In the user terminal 130, a virtual character may divide a virtual space into at least one area. For example, if the virtual space is a house, at least one area may be divided into an entrance, a living room, a kitchen, a room, or a veranda. The user terminal 130 may determine the time the virtual person stays in at least one area as the time the virtual person stays in the location in the virtual space. The user terminal 130 may acquire identification information of at least one area and time spent in the at least one area. The time the virtual character stays in at least one region may have a unit of minutes or seconds.

The user terminal 130 may obtain a virtual object displayed on the display of the user terminal at the position of the virtual person. The user terminal 130 may obtain the identification information of the virtual object displayed on the user terminal 130 at predetermined cycles even if the virtual person does not interact with the virtual object. The predetermined period may be 5 seconds, 10 seconds or 1 minute, or 10 minutes or the like. For example, if the virtual space is a park and the virtual character is sitting on a park bench, the virtual character is interacting with the virtual object, the park bench. The user terminal 130 may display not only the virtual character sitting on a bench, but also trees, grass, and streetlights around the virtual character. The user terminal 130 may periodically obtain identification information of virtual objects displayed on the user terminal while being around the virtual person. Such displayed virtual object identification information may be utilized as a user's predicted preference object. That is, the displayed virtual object identification information may be used as information representing a user's taste.

A process of obtaining log information will be described in more detail with reference to FIG. 10 for a moment.

The user terminal 130 may further perform the following process in order to perform step 420 of acquiring log information. The user terminal 130 may perform a step of acquiring the resolution of the display 1010 of the user terminal 130 . The resolution of the display 1010 may mean the maximum resolution of the display. The resolution may include the number of horizontal pixels and the number of vertical pixels. The user terminal 130 may perform a step of setting a predetermined partial region of the display as the region of interest 1020 based on the resolution of the display 1010 . For example, the user terminal 130 may determine the area of interest 1020 to have an area greater than 1/8 and less than 1/4 of the area of the resolution of the display 1010 . Also, the user terminal 130 may determine that the center of the region of interest 1020 coincides with the center of the display 1010 . The user terminal 130 may perform a step of including, in the log information, virtual object information of interest including identification information of a virtual object displayed in the region of interest for a predetermined threshold time or longer. Here, the threshold time may have a value of 10 seconds or more. Positioning the virtual object in the center of the screen for at least a predetermined period of time may indicate that the user expressed interest in the virtual object. Accordingly, the user terminal 130 may include identification information of a virtual object displayed in the region of interest for a threshold period of time or longer in the log information. The user terminal 130 or the server 110 may later use the log information as big data to derive virtual objects preferred by the user. Accordingly, the user terminal 130 or the server 110 may provide a user-customized virtual object.

Referring back to FIG. 4 , the user terminal 130 may perform step 430 of transmitting log information to the server 110 together with identification information of the user terminal. The user terminal 130 may collect log information for a predetermined period of time. Also, the user terminal 130 may transmit log information collected during a predetermined time to the server 110 . The user terminal 130 may transmit log information to the server 110 in response to user identification information. The user terminal 130 may delete log information transmitted to the server 110 . The server 110 may accumulate and store log information. By deleting log information from the user terminal 130 in this way, memory of the user terminal 130 can be saved. In addition, since the log information is used only as big data in the server 110 and is not utilized in the user terminal 130, it has an effect of being stored only where necessary.

In FIG. 2 , step 311 in which the server 110 obtains the property of the virtual object may include the following process. The manager terminal 120 or the user terminal 130 may perform step 511 of obtaining a source image including a real object or real item using an image capture device. The image capture device may be a 2D camera or a 3D camera. If the image capture device is a 2D camera, the manager terminal 120 or the user terminal 130 may obtain source images for six sides of a real object or real item. The six sides may include a front view, a rear view, a left view, a right view, a top view, and a bottom view. The manager terminal 120 or the user terminal 130 may generate information about the 3D shape of a rectangular parallelepiped using 6 plane views of a real object or real item. When the image capture device is a 3D camera, the manager terminal 120 or the user terminal 130 may acquire information about the 3D shape of a real object or real item as a source image. Information on the 3D shape may be 3D modeling data. Information about a three-dimensional shape may be for a closed polyhedron.

A source image including a real object or real item may include at least one of a tag, a 6-side view, and information on a 3D shape of the real object or real item. A tag for a real object or real item may be at least one term for describing the real object or real item. The tag may include at least one of the type and brand of a real object or real item. The tag may be a mark such as QR or barcode attached to a real object or real item.

The manager terminal 120 or the user terminal 130 may perform step 512 of obtaining properties of a real object or a property of a real item from a source image. Properties of real objects or properties of real items may correspond to properties of virtual objects or properties of virtual items that have already been described. The property of the real object or the property of the real item may include at least one of identification information, type, texture (texture), color, shape, size, and position of the object or item. A description of the information included in the properties of the real object or the properties of the real item is omitted because it overlaps with the description of the information included in the properties of the virtual object or the virtual item.

The manager terminal 120 or the user terminal 130 may receive properties of real objects or properties of real items from the server 110 . For example, the manager terminal 120 or the user terminal 130 may obtain an image of a tag of a real object. The manager terminal 120 or the user terminal 130 may include a photographing unit, and may obtain an image of the tag using the photographing unit. The manager terminal 120 may obtain identification information of a real object from the image of the tag. Identification information of the real object may be associated with at least one of item, serial number, brand, or manufacturing date of the real object. The manager terminal 120 or the user terminal 130 may transmit identification information of a real object to the server 110 . The server 110 may obtain attributes of a real object corresponding to the identification information of the real object from a pre-stored database. The server 110 may transmit the properties of the virtual object to the manager terminal 120 or the user terminal 130 . A user or manager may check properties of the received virtual object. If there is no property of a real object corresponding to identification information of a real object in the pre-stored database, the server 110 transmits a signal requesting the property of the real object to the manager terminal 120 or the user terminal 130. can

The manager terminal 120 or the user terminal 130 may obtain some of the attributes of the real object based on the source image. For example, the manager terminal 120 or the user terminal 130 may acquire a picture or shape displayed on a real object based on a source image. More specifically, if the actual object is a signboard, the manager terminal 120 or the user terminal 130 may automatically obtain a letter, figure, or picture displayed on the signboard based on the source image.

The manager terminal 120 or the user terminal 130 may obtain the type of object by applying an object recognition algorithm to the source image. The object recognition algorithm may be implemented based on a machine learning model. The manager terminal 120 or the user terminal 130 may display the type of recognized object. In addition, when receiving the user's confirmation signal, the manager terminal 120 or the user terminal 130 may determine the type of the real object as the type of the recognized object.

The manager terminal 120 or the user terminal 130 may receive identification information included in the property of a real object from a manager or a user. Alternatively, the manager terminal 120 or the user terminal 130 may request the server 110 to generate identification information, and the server 110 may automatically generate identification information. The manager terminal 120 or the user terminal 130 may determine the automatically generated identification information as the identification information of the actual object.

The manager terminal 120 or the user terminal 130 may receive the type of real object from the manager or the user. The manager terminal 120 or the user terminal 130 may acquire the texture and color of a real object from a source image. The manager terminal 120 or the user terminal 130 may extract the texture or color of a real object from an area included in the object of the source image. The manager terminal 120 or the user terminal 130 may obtain the shape of the real object from information on the 3D shape. The manager terminal 120 and the user terminal 130 may generate the shape of a real object using a specialized 3D modeling tool. Also, the manager terminal 120 or the user terminal 130 may acquire the size of the actual object from the manager or user or from information about the 3D shape. The manager terminal 120 or the user terminal 130 may obtain the location of the real object from the manager or the user.

The server 110 may perform step 513 of receiving a source image and properties of a real object or properties of a real item from the manager terminal 120 or the user terminal 130 . The server 110 may perform step 521 of storing the source image together with properties of real objects or properties of real items. The server 110 may perform step 522 of obtaining a property of a virtual object or a property of a virtual item based on at least one of a source image, a property of a real object, or a property of a real item. More specifically, the server 110 may determine a property of a real object or a property of a real item as a property of a virtual object or a property of a virtual item. In the above manner, the server 110 may accumulate and store the attributes of virtual objects or virtual items. Also, the server 110 may fill the virtual space by using at least one attribute of a plurality of virtual objects based on a control signal of the manager terminal 120 or the user terminal 130 . Also, the server 110 may decorate a virtual person by using at least one of attributes of a plurality of virtual items based on a control signal of the user terminal 130 . When a user or another user clicks (touches) a virtual item possessed by a virtual person using a user terminal, a 3D shape of the virtual item may be popped up. For example, the 3D form may be a source image for 6 sides of an actual item. Source images for the 6 faces may be displayed on the surface of the 6 faces. In this case, the reality of the item in the virtual space may be lowered, but the user can show off the item he actually owns in the virtual space, and the effect of easily satisfying the user's desire to show off without causing much problems with the license of the item there is

As already described, the metaverse system may include the user terminal 130 and the server 110. The user terminal 130 may perform step 611 of acquiring authentication information by scanning a tag attached to an item owned by the user. The items owned by the user may be clothes, bags, electronic products, and shoes that the user actually owns in the real world. A tag may be attached to an item owned by the user. In the tag, a serial number may be written on an item owned by the user. The serial number may include unique identification information and authentication information of the item. That is, if the serial number has a specific pattern, the corresponding item is genuine, and if it does not have a specific pattern, the corresponding item may not be genuine.

According to an embodiment of the present disclosure, the user terminal 130 may capture a tag using a camera. The user terminal 130 may obtain authentication information based on the image of the tag. For example, a tag can be a barcode or QR code. However, it is not limited thereto.

Also, the tag may include a communication unit. The communication unit of the tag may communicate with the user terminal 130 . The communication method may use Near Field Communication (NFC) or Bluetooth. The user terminal 130 may acquire authentication information by communicating with the tag.

According to another embodiment of the present disclosure, authentication information may be a One Time Password. Authentication information may have a value that changes over time. For example, an item owned by a user may include a battery and a power generation unit that generates power by light. The control unit of the item owned by the user may receive power from the battery and the power generation unit. In addition, the control unit of the item owned by the user may generate an authentication number that changes according to time by applying a predetermined algorithm to the current time. The server 110 may also generate an authentication number that changes according to time by applying a predetermined algorithm to the current time. That is, the authentication number generated by the item owned by the user may be the same as the authentication number generated by the server 110 . The user terminal 130 may automatically or manually obtain an authentication number generated by an item owned by the user.

The user terminal 130 may perform step 612 of transmitting authentication information, user identification information, and identification information of the user terminal to the server 110 . User identification information may be unique information for each user. The identification information of the user may include information on at least one of a name, biometric information (iris, fingerprint), resident registration number, date of birth, or phone number. In addition, the user's identification information may be unique information generated based on information on at least one of a name, resident registration number, date of birth, or phone number. Also, the user's identification information may be unique information input by the user.

The identification information of the user terminal may be unique information for each user terminal. Identification information of the user terminal may include information on at least one of a phone number, a device serial number, a manufacturer, a production number, a production date, or a model name. Also, the identification information of the user terminal may be unique information generated based on information on at least one of a phone number, a device serial number, a manufacturer, a production number, a production date, or a model name.

In step 612, the user terminal 130 may further transmit a command requesting authentication to the server 110. The server 110 may perform authentication on the user terminal 130 based on a command requesting authentication. However, it is not limited thereto. A command requesting authentication from the user terminal 130 may not be transmitted to the server 110 . When the server 110 receives authentication information, user identification information, and user terminal identification information, it may perform authentication for the user terminal.

In step 612, the user terminal 130 may encrypt authentication information, user identification information, and identification information of the user terminal, and server 110 may encrypt the authentication information, user identification information, and user terminal identification information. can decrypt.

The server 110 may perform step 621 of determining whether the authentication information corresponds to the pre-stored virtual item and is legitimate. The server 110 may store identification information of virtual items in advance. In addition, the server 110 may store authentication information to correspond to identification information of a virtual item. The server 110 may compare stored authentication information and virtual item identification information with authentication information and virtual item identification information received from the user terminal 130 . When the stored authentication information and the identification information of the virtual item are the same as the authentication information received from the user terminal 130 and the identification information of the virtual item, the server 110 determines that the authentication information corresponds to the identification information of the virtual item and is legitimate. can decide

If the stored authentication information and identification information of the virtual item are not the same as the authentication information and identification information of the virtual item received from the user terminal 130, the server 110 determines that the authentication information does not correspond to the identification information of the virtual item. may or may not be justified. The server 110 may control the user terminal 130 to display an error message when the previously stored authentication information is different from the authentication information received from the user terminal 130 .

In addition, if the identification information of the virtual item stored in advance is different from the identification information of the virtual item received from the user terminal 130, the server 110 identifies the item owned by the user among the virtual items stored in the server 110. The most similar virtual item may be determined to be legitimate. The server 110 may divide and store previously stored virtual items into a plurality of groups. The server 110 may control the user terminal 130 to display an unlicensed virtual item belonging to the same group as the identification information of the virtual item received from the user terminal 130 . Here, the non-license may mean a virtual item that does not cause a license problem. For example, it may mean a virtual item that can be freely used by a metaverse system provider through a contract in advance or a license-free virtual item. The server 110 may determine one virtual item as a legitimate item based on the user's selection information received from the user terminal 130 .

When the authentication information corresponds to the identification information of the virtual item and is determined to be valid, the server 110 stores the identification information of the virtual item and the identification information of the user terminal in the authenticated user item list corresponding to the user's identification code ( 622) can be performed. The server 110 may generate an authenticated user item list for each user. The server 110 may obtain an authenticated user item list corresponding to the user identification code. In addition, the server 110 may store the identification information of the virtual item and the identification information of the user terminal in the authenticated user item list corresponding to the user's identification code. The authenticated user item list may include identification information of authenticated virtual items. That is, identification information of virtual items that have not been authenticated by the server 110 may not be included in the authenticated user item list. The reason for simultaneously storing the identification information of the virtual item and the identification information of the user terminal in the user item list may be to determine whether the user's virtual character can wear the virtual item. The server 110 receives a request from the user terminal 130 corresponding to the identification information of the user terminal, and allows the virtual person to wear the virtual item corresponding to the identification information of the virtual item included in the user item list. there is. Accordingly, virtual items may be used only in a specific user terminal 130 . Through this, virtual items can be prevented from being used in a plurality of user terminals 130, and rights of copyright holders or brand licensors can be protected.

When it is determined that the authentication information does not correspond to the identification information of the virtual item or is invalid, the server 110 may transmit information indicating that authentication has not been performed to the user terminal 130 . The user terminal 130 may help the user to normally perform authentication by outputting information indicating that authentication has not been performed.

The server 110 may perform step 623 of transmitting information on the authenticated user item list to the user terminal 130 . Information on the authenticated user item list may include information on authenticated virtual items. Information on the list of authenticated user items includes the copyright holder of the authenticated virtual item or the item owned by the user, the producer, when the item was produced, when the item was released, the order of production of the item, the brand, the item of the item, the shape of the item, or , may include information on at least one of the materials of the item. The user terminal 130 may perform a step of outputting information on the authenticated user item list. In this way, the user can use the items owned by the user in the metaverse. Accordingly, the user can use the item he or she likes both in real and virtual space, and thus, satisfaction can be increased.

The step 332 of displaying the virtual character, virtual space, and virtual object on the display may further include the following process. Based on the user's selection, the user terminal 130 may perform step 631 of obtaining information about the virtual person by using at least one of the at least one item included in the user item list. As described above, the information on the virtual character may include information on the item possessed by the virtual character, and at least one virtual item included in the user item list may be determined as the item possessed by the virtual character.

Authenticated virtual items can be checked in the virtual space using the user terminal.

FIG. 7 may be performed after FIG. 6 . The server 110 may perform step 710 of requesting authentication information acquired by scanning the tag to the user terminal at predetermined intervals. The predetermined period may be one of a week, a month, a year or three years. The predetermined period may be progressively longer based on a time elapsed from the release of the virtual item or the item owned by the user. That is, the predetermined cycle may increase in proportion to a time elapsed from the release time of the virtual item or the item owned by the user. For example, the predetermined cycle up to one month after the release of the virtual item or the item owned by the user may be one week. However, after one month after the release of the virtual item or the item owned by the user, the predetermined cycle may be one month, and after one year after the release of the virtual item or the item owned by the user, the predetermined cycle may be one year. Also, there may not be a predetermined cycle after a threshold time elapses after the release of a virtual item or an item owned by a user. That is, after the threshold time has elapsed, authentication for virtual items or items owned by the user may not be performed.

Also, the server 110 may perform additional authentication regardless of a predetermined period. The server 110 may perform re-authentication as shown in FIG. 5 when a user terminal that is not stored in the user's authenticated user item list tries to access a virtual item.

The server 110 may set a predetermined period for each authenticated user item list. When a predetermined period arrives, the server 110 may request authentication information from the user terminal based on identification information of the user terminal stored in the authenticated user item list.

In response to the request of the server 110, the user terminal 130 may perform step 721 of outputting information indicating that authentication information should be obtained by scanning the tag. Based on the output information, the user can scan the tag using the user terminal 130 . The user terminal 130 may obtain authentication information.

The server 110 may perform step 722 of re-receiving authentication information obtained by scanning the tag, identification information of the user, and identification information of the user terminal from the user terminal. In FIG. 6, since the server 110 has received authentication information, identification information of the user, and identification information of the user terminal, the information received by the server 110 for re-authentication in FIG. It is referred to as user identification information and re-received identification information of the user terminal.

The re-received authentication information corresponds to the re-received identification information of the re-received virtual item and is legitimate, and the re-received identification information of the re-received virtual item in the authenticated user item list corresponding to the re-received user identification code and the re-received user terminal identification information. If the identification information is included, the server 110 may perform a step of maintaining the identification information of the virtual item in the authenticated user item list and the identification information of the user terminal.

Unlike FIG. 6, the server 110 further determines whether or not identification information of the re-received virtual item and identification information of the re-received user terminal are included in the authenticated user item list corresponding to the re-received user identification code. can judge Also, when the condition is satisfied, the server 110 may maintain the identification information of the virtual item in the authenticated user item list and the identification information of the user terminal.

The re-received authentication information corresponds to the re-received identification information of the re-received virtual item and is legitimate, and the re-received identification information of the re-received virtual item in the authenticated user item list corresponding to the re-received user identification code and the re-received user terminal identification information. If the identification information is not included, the server 110 may perform a step of storing the identification information of the re-received virtual item and the re-received identification information of the user terminal in the authenticated user item list. The server 110 stores the identification information of the re-received virtual item and the re-received identification information of the user terminal in the authenticated user item list, so that the user forgets his or her virtual item and does not register it in the server 110. can prevent In addition, even if the identification information of a virtual item is deleted from the user item list of the server 110 by error, the identification information of the virtual item can be restored through the above process. Therefore, the user may not feel any inconvenience even if an error occurs.

If the re-received authentication information does not correspond to the re-received identification information of the virtual item or is not legitimate, the server 110 may perform a step of deleting the identification information of the virtual item from the authenticated user item list. Therefore, even if the user later requests a virtual item using the user terminal 130 , the server 110 may not provide virtual item data to the user terminal 130 . Accordingly, the virtual person used by the user may not be able to wear the corresponding virtual item.

As already described, the server 110 may perform step 710 of requesting authentication information from the user terminal 130 at predetermined intervals. The user terminal 130 may output information indicating that authentication information should be obtained. However, since the user does not have an item owned by the user, authentication information may not be obtained from the item owned by the user.

If the server 110 does not receive a reply from the user terminal within a predetermined period of time after requesting the authentication information, a step of deleting at least one of the identification information of the virtual item and the identification information of the user terminal from the authenticated user item list is performed. can Here, the predetermined period may be one week, one month, one year or three years. However, it is not limited thereto. The server 110 may control the predetermined period to increase in proportion to the elapsed time from the release of the virtual item or the item owned by the user. For example, the predetermined period up to one month after the release of the virtual item may be one week. However, after one month after the release of the virtual item or the item owned by the user, the predetermined period may be one month, and after one year after the release of the virtual item or the item owned by the user, the predetermined period may be one year. In addition, there may be no predetermined period after a threshold time elapses after the release of a virtual item or an item owned by a user. That is, after the threshold time has elapsed, authentication for virtual items or items owned by the user may not be performed.

The user terminal 130 may perform a step of receiving an input for requesting the use of at least one virtual item among the information on the authenticated user item list from the user. As already described, the user terminal 130 may receive information about the authenticated user item list from the server 110 . The user terminal 130 may output information about the authenticated user item list. The output can be video or sound. Information on the list of authenticated user items is at least one of the copyright holder of the authenticated virtual item, the producer, the time of production of the item, the time of release of the item, the order of production of the item, the brand, the item of the item, the shape of the item, or the material of the item. It may contain information about one. The user may use the input unit of the user terminal 130 to input to the user terminal 130 to use one virtual item among information on the authenticated user item list.

In response to receiving an input for using at least one virtual item, the user terminal 130 transmits usage request information including identification information for the requested virtual item, user identification information, and identification information of the user terminal to the server ( 110) may be performed.

According to an embodiment of the present disclosure, the user terminal 130 transmits the identification information for the requested virtual item, the user identification information, and the identification information of the user terminal to the server 110 without a separate command, and the server 110 ) is requesting the use of a virtual item. According to another embodiment of the present disclosure, the user terminal 130 may transmit a command requesting use to the server 110 together with identification information for the requested virtual item, user identification information, and identification information of the user terminal. . The server 110 may know that the user terminal 130 is requesting use based on the command requesting use.

The server 110 may perform a step of determining whether identification information for the requested virtual item and identification information of the user terminal are included in the authenticated user item list corresponding to the identification information of the user included in the use request information. The server 110 may obtain the user's authenticated user item list based on the user's identification information included in the use request information. In addition, the server 110 may determine whether identification information for the requested virtual item and identification information of the user terminal included in the play request information are included in the obtained authenticated user item list.

When the authenticated user item list includes the identification information of the requested virtual item and the identification information of the user terminal, the server 110 transmits data of the virtual item corresponding to the identification information of the requested virtual item to the user terminal 130. ) can be performed. Data of the virtual item may be stored by the server 110 . However, the present invention is not limited thereto, and the server 110 may control a separate virtual item cloud server to provide virtual item data to the user terminal 130 . Here, data of the virtual item may include modeling data of the virtual item.

Data of the virtual item may include content not included in the item owned by the user. For example, although music or video is not played on an item owned by the user, music or video may be played when the virtual person wears the virtual item. Accordingly, the server 110 may induce users to authenticate an item they actually own to the server 110 .

The purchaser terminal 810 may perform step 821 of acquiring authentication information. The purchaser terminal 810 may be different from the user terminal 130 . Also, the owner of the purchaser terminal 810 may be different from the owner of the user terminal 130 . The user may be a user who initially purchases an item owned by the user. Also, the user terminal 130 may be a user terminal that authenticates an item owned by the user for the first time. The purchaser may be a person who purchases an item owned by the user from the user. The purchaser's terminal 810 may be a purchaser's terminal.

According to an embodiment of the present disclosure, a process in which the purchaser terminal 810 obtains authentication information may be the same as a process in which the user terminal 130 obtains authentication information. For example, the purchaser terminal 810 may obtain authentication information from a tag using a camera. A tag may include a communication unit. The communication unit of the tag may communicate with the purchaser terminal 810 . The communication method may use Near Field Communication (NFC) or Bluetooth. The purchaser terminal 810 may obtain authentication information by communicating with the tag. As already described, the authentication information may be a One Time Password.

According to an embodiment of the present disclosure, a process in which the purchaser terminal 810 obtains authentication information may be different from a process in which the user terminal 130 obtains authentication information.

The user terminal 130 may request transmission of authentication information to the purchaser terminal 810 . When the user terminal 130 requests transmission of authentication information to the purchaser terminal 810, the user terminal 130 distributes and shares transmission/reception detail information for the authentication information to the server, the user terminal, and the purchaser terminal. can be done The server, the user terminal, and the purchaser terminal may be interconnected through a blockchain network.

Here, the transmission/reception detail information may include detailed information of the right holder including the name of the copyright holder or trademark holder of the virtual item related to the authentication information. The transmission/reception detail information may include detailed information on virtual items related to authentication information. The transmission/reception detail information may include detailed rights information including whether or not a trademark is registered for a virtual item related to authentication information, a trademark owner, a copyright owner, a copyright expiration date, a limit on the number of times of resale, or an expiration date of resale. The transmission/reception detail information may include detailed information related to a user terminal that purchased or sold a virtual item related to authentication information and a purchaser terminal.

The server 110, the user terminal 130, and the purchaser terminal 810 may each perform a step of deriving a hash value based on transmission/reception detail information for authentication information.

The server 110, the user terminal 130, and the purchaser terminal 810 may generate a hash value by processing transmission/reception detail information of virtual item data using a hashing algorithm.

When the hash values of the server 110 , the user terminal 130 , and the purchaser terminal 810 match each other, the purchaser terminal 810 may perform a step of transmitting payment information for authentication information to the server. In order to determine whether the hash values of the server 110, the user terminal 130, and the purchaser terminal 810 match, the hash values generated by each device may be mutually shared. That is, the hash value generated by the server 110 may be shared by the user terminal 130 and the purchaser terminal 810, and the hash value generated by the user terminal 130 is shared by the server 110 and the purchaser terminal 810. , and the hash value generated by the purchaser terminal 810 may be shared by the server 110 and the user terminal 130 . The server 110, the user terminal 130, and the purchaser terminal 810 may determine that the mutually shared hash values match each other.

Payment information for authentication information may be payment information for a purchaser to purchase an item owned by the user or data of a virtual item from the user using the purchaser terminal 810 . Payment information may include information necessary for payment. For example, the payment information may include a payment amount, credit card information, or payment bank information. When the purchaser terminal 810 transmits payment information for authentication information to the server 110 , it may mean that the purchaser terminal 810 has paid the server 110 the payment amount.

When the server 110 receives payment information, the server 110 may perform a step of transmitting transaction approval information to the user terminal 130 . The transaction approval information may indicate that the server 110 has approved the virtual item data transaction between the user terminal 130 and the purchaser terminal 810 . The server 110 may deliver to the user an amount obtained by subtracting a fee from a service company or a copyright fee from a copyright owner among the amounts received from the purchaser terminal.

Based on the transaction approval information, the user terminal 130 may perform a step of transmitting authentication information to the purchaser terminal 810 . That is, the user terminal 130 may receive transaction approval information and transmit authentication information to the purchaser terminal 810 when it is determined that the transaction approval information is legitimate. Transmission of virtual item data may not occur between the user terminal 130 and the purchaser terminal 810 . The purchaser terminal 810 may receive virtual item data through the server 110 based on authentication information.

So far, the process of receiving authentication information by the purchaser terminal 810 has been described. Hereinafter, a process in which the purchaser terminal 810 updates the authenticated user item list in the server 110 based on authentication information together with FIG. 8 will be described.

Referring to FIG. 8 , the purchaser terminal 810 transmits authentication information, identification information of a virtual item based on a real item owned by a user, purchaser identification information, and purchaser terminal identification information to the server 110 ( 822) can be performed. Step 822 may be the same as step 612 or step 722 except that the subject of execution is different. Therefore, redundant descriptions are omitted.

The server 110 may perform step 831 of determining whether the authentication information corresponds to the identification information of the virtual item and is legitimate. This step may be the same as step 621. Therefore, redundant descriptions are omitted.

When it is determined that the authentication information corresponds to the identification information of the virtual item and is legitimate, the server 110 may perform step 832 of deleting the identification information of the virtual item from the authenticated user item list corresponding to the user's identification code. there is. Since the right to use the virtual item is transferred from the user to the purchaser, the server 110 deletes the identification information of the virtual item from the list of authenticated user items corresponding to the user's identification code, thereby preventing the user from using the virtual item any longer. can do. Before deleting the identification information of the virtual item from the authenticated user item list corresponding to the user's identification code, the server 110 transmits information indicating that the identification information of the virtual item will be deleted from the authenticated user item list to the user terminal 130. ) can be transmitted. Accordingly, the user can clearly know that he or she will not be able to use the virtual item.

The server 110 may perform step 833 of storing the identification information of the virtual item and the identification information of the purchaser terminal 810 in the authenticated purchaser item list corresponding to the purchaser's identification code. Since the purchaser has secured the legitimate right to the virtual item, the server 110 stores the identification information of the virtual item and the identification information of the purchaser terminal in the purchaser item list, thereby permitting the purchaser terminal 810 to use the virtual item. can

The server 110 may perform step 834 of transmitting information about the authenticated buyer item list corresponding to the buyer's identification code to the buyer terminal 810 . Step 834 may be similar to step 623 . Therefore, redundant descriptions are omitted. In addition, the purchaser terminal 810 obtains information about the purchaser's virtual character by using at least one item among at least one item included in the purchaser's item list corresponding to the purchaser's identification code based on the purchaser's selection (841). can be performed. Step 841 may be similar to step 631 . Therefore, redundant descriptions are omitted.

Step 324 of the server 110 transmitting information about the 3D virtual space to the user terminal 130 may include the following process. In step 1111, the manager terminal 120 transmits to the server 110 identification information of the user terminal 130, identification information of the user, and information related to a contract for sale or lease of a real space corresponding to the virtual space. can do. The manager may be one of a real space lessor, a real space seller, or a real space broker. Information related to a contract for sale or lease of a real space corresponding to a virtual space may include the date of the contract, identification information of the subject of the contract, price of the subject of the contract, and information on the parties to the contract and the contents of the contract. Here, the contract subject may be an actual space. In addition, the identification information of the subject of the contract may include the location, designation, or area of the actual space. The contents of the contract may include a rental contract or a sales contract. Parties to the contract may include at least one of a buyer, a seller, a lessor, or a lessee. The manager terminal 120 may transmit information related to the contract to the server 110 in order to conclude the contract. That is, the information related to the contract may include various types of information necessary before signing the contract. Through this process, the manager terminal 120 can subscribe for a contract.

The server 110 may perform step 1121 of transmitting information related to a sale or lease contract of real space to the user terminal 130 . The server 110 may store information related to a contract for sale or lease of a real space corresponding to a virtual space. In the metaverse system of the present disclosure, since the manager terminal 120 must transmit information related to the contract to the user terminal 130 through the server 110, the possibility of falsification of the contents of the contract can be reduced.

The user terminal 130 may perform step 1131 of transmitting acceptance information regarding information related to a contract for sale or rental of real space, identification information of the user terminal, and identification information of the user to the server 110 . That is, the user may accept the contract through the user terminal 130 .

When the server 110 receives the consent information, the identification information of the user terminal and the identification information of the user received from the manager terminal 120 are combined with the identification information of the user terminal and the identification information of the user received from the user terminal 130. Step 1141 of determining whether they are the same may be performed. The user may also input user identification information and terminal identification information to the manager terminal 120 . That is, users and administrators may need to be in the same space. When the identification information of the user terminal and the identification information of the user received from the manager terminal 120 are the same as the identification information of the user terminal and the identification information of the user received from the user terminal 130, the server 110 determines that the consent information is legitimate. can decide that The server 110 may receive and store identification information of the manager terminal and manager identification information from the manager terminal 120 and receive and store identification information of the user terminal and user identification information from the user terminal 130 .

However, it is not limited thereto. The server 110 receives consent information, receives and stores identification information of the manager terminal and manager identification information from the manager terminal 120, and receives identification information of the user terminal and user identification information from the user terminal 130. and can be saved. The server 110 may determine that the consent information is legitimate without any confirmation.

When the identification information of the user terminal and the identification information of the user received from the manager terminal 120 are the same as the identification information of the user terminal and the identification information of the user received from the user terminal 130, the server 110 sends the user terminal 130 ), step 1142 of transmitting information on the 3D virtual space can be performed. Therefore, the user can use the virtual space using the user terminal 130 . Since the user's wandering around the virtual space using the virtual person has already been described in step 410, a duplicate description will be omitted. In addition, the server determines whether the identification information of the user terminal and the identification information of the user received from the manager terminal 120 are the same as the identification information of the user terminal and the identification information of the user received from the user terminal 130. When consent information is received from , step 1142 of transmitting information on a 3D virtual space to the user terminal 130 may be performed.

When the server 110 receives the consent information, at least one of information related to a contract for sale or rental of a real space corresponding to a virtual space, user identification information, identification information of a user terminal, manager identification information, and identification information of a manager terminal may be stored in an unmodifiable storage of the server 110. The storage may be an Inter-Planetary File System (IPFS). The server may issue two NFTs (Non Fungible Tokens) to information related to a sale or lease contract of real space. The issued NFTs can be transmitted to the manager terminal and user terminal, respectively. The manager terminal 120 and the user terminal 130 can access information related to a contract for sale or lease of real space stored in IPFS by using the hash value of the NFT, but may not arbitrarily change the contents of the contract. Therefore, the possibility of tampering with the contents of the contract can be greatly reduced.

As already described, the server 110 may perform step 1142 of transmitting information about the 3D virtual space to the user terminal 130 . After that, the user can manipulate the virtual character in the virtual space using the user terminal 130 . In addition, the user can communicate with other users in the virtual space using the user terminal 130 . Other users may also be users who have received information about the 3D virtual space from the server through the above process.

More specifically, in Korea's apartment subscription system, users cannot experience the life of an apartment at all from the time the apartment is sold until the apartment is built. However, the metaverse system according to the present disclosure can implement an apartment complex to be built in a virtual space. Therefore, users who have received an apartment can enjoy life in a real apartment while walking around the apartment in the virtual space. That is, the metaverse system of the present disclosure provides a virtual space in which users experience an apartment complex in advance before moving in, and the virtual space can be used as a space to provide various information related to the situation before moving in. For example, the metaverse system of the present disclosure may inform users of the progress of construction, or inform intermediate payment, balance payment method, payment date, and the like. In addition, the metaverse system of the present disclosure can be utilized as a community of apartments in virtual space. Residents can engage in various social activities in virtual space using the metabus and receive online services.

The user terminal 130 may perform step 420 of acquiring log information. More specifically, the user terminal 130 may perform a step of acquiring the resolution of the display 1010 of the user terminal 130 . The resolution of the display may be pre-stored in a memory. The user terminal 130 may perform a step of setting a predetermined partial region of the display as the region of interest 1020 based on the resolution of the display. The user terminal 130 may perform a step of including, in the log information, virtual object information of interest including identification information of a virtual object displayed in the region of interest for a predetermined threshold time or longer. Here, the threshold time may have a value of 10 seconds or more. Positioning the virtual object in the center of the screen for at least a predetermined period of time may indicate that the user expressed interest in the virtual object. Accordingly, the user terminal 130 may include identification information of a virtual object displayed in the region of interest for a threshold period of time or longer in the log information. The user terminal 130 or the server 110 may later use the log information as big data to derive virtual objects preferred by the user. Accordingly, the user terminal 130 or the server 110 may provide a user-customized virtual object.

The user terminal 130 may perform a step of including virtual object information of interest, including the virtual object that the virtual character has interacted with and the content of the interaction, in the log information. Interactions between virtual characters and virtual objects may be predetermined. For example, the predetermined interaction may change a posture of a virtual character or a position, color, or shape of a virtual object. For example, if the virtual object is a chair, the virtual character can interact to sit on the virtual object. The virtual character may perform a sitting motion on the virtual object. Also, if the virtual object is a light, the virtual character can take an action to turn on or turn off the light. The virtual object may be turned on or off in response to the motion of the virtual character. If the virtual object is a seesaw, the virtual character can interact to sit on the virtual object, and the seesaw, which is a virtual object, can move in response to the motion of the virtual character sitting down. Identification information may be assigned to the predetermined interaction. The user terminal 130 may include the identification information of the virtual object with which the virtual character interacted and the identification information of the interaction in interest virtual object information.

The user terminal 130 may perform a step of including the conversation contents of the virtual character with other users' virtual characters or non-player characters (NPCs) in the log information. The content of the conversation may include information about what needs to be improved in the virtual space or about virtual objects of interest. If the virtual space is an apartment complex before moving in, users who have received a sale can receive You can experience life after moving into an apartment in a virtual space. Also, in the virtual space, the commercial space of an apartment complex can be used as a space where residents can receive coupons for promotion. For example, the user can move to a specific space of the virtual space using the user terminal 130 . The specific space may be a space of a location designated by the server 110 . A specific space may be included in the commercial space. The server 110 may issue coupons to virtual characters in the shopping mall. Coupons may include serial numbers, QR codes or barcodes. Users can use coupons received from the metaverse at real stores. Also, the coupon may be a digital discount voucher. The user terminal 130 may transmit the coupon to the server 110 . The server 110 may control to display at least one virtual item corresponding to the coupon on the user terminal 130 . A user may select one of at least one virtual item using the user terminal 130 . The server 110 may store identification information of the virtual item selected in response to the user's selection and identification information of the user terminal in the user item list. Through the above process, the metabus system can induce virtual characters to wander around in the virtual space.

The server 110 may accumulate and store movement lines of virtual characters. The server 110 may transmit the corresponding movement to the manager terminal 120 when there is a movement of the virtual characters separated by a predetermined distance or more from a pre-designed road. The manager terminal 120 may display the corresponding movement line on the display. Among the movement lines of the virtual characters, a previously designed road that is more than a predetermined distance apart may be an optimal route when users go from one point to another. However, if roads are not designed in the corresponding traffic line, it may cause inconvenience to residents in reality. The manager can decide whether a road design is required for that route.

Based on the log information, the server 110 may perform a step of determining information about a congestion location where a plurality of users often hear in a virtual space. As described above, the log information may periodically acquire the location of the user. The server 110 may obtain the distribution of virtual characters at the same time. The server 110 may determine congestion locations according to time based on the distribution of virtual characters. For example, if more than a critical number of virtual characters are gathered around a location at one point in time, it may be determined that the location is crowded at one point in time. Also, if less than a critical number of virtual characters are in the vicinity of a location at a point in time, it may be determined that the location is not congested at a point in time.

The server 110 may perform a step of determining a rent or sale price of a shopping mall as it is closer to the location of the real space corresponding to the congested location. That is, patterns of real users may be simulated based on patterns of virtual characters in the virtual space, and through this, it is possible to determine a high rent or sale price around a location where congestion is predicted to be high. Therefore, it is possible to realize the realization of the commercial sale price.

The server 110 may perform a step of determining a virtual object frequently used by a plurality of users based on the virtual object information of interest included in the log information. Since the virtual object information of interest has already been described, a duplicate description will be omitted. The virtual object information of interest may be obtained for a plurality of virtual characters. The server 110 may obtain virtual object information of interest of a plurality of virtual characters and determine virtual object information of the highest interest or frequently used. Also, the server 110 may perform a step of transmitting frequently used virtual objects to the manager terminal 120 . If the virtual space is still under construction in reality, the administrator can implement frequently used virtual objects in reality. For example, if a virtual character often sits on a bench at a specific location, the number of benches at that location in reality can be increased. In addition, if the preference for one of the benches of various designs is high in the virtual space, the bench in the complex can be implemented as a bench with a high preference in reality.

The user terminal 130 may perform a step of transmitting to the server 110 a purchase signal for a purchase object included in a plurality of candidate virtual objects stored in the server 110, identification information of the user, and identification information of the user terminal. can A purchase signal for a purchase object may include identification information for the purchase object.

The server 110 may perform a step of determining whether the purchase signal is legitimate. For example, the server 110, the user terminal 130, and the manager terminal 120 may each perform a step of deriving a hash value based on transmission/reception detail information on a purchase signal for a purchase object. The server 110, the user terminal 130, and the manager terminal 120 may generate a hash value by processing transmission/reception detail information of a purchase signal for a purchase object using a hashing algorithm. When the hash values of the server 110, the user terminal 130, and the manager terminal 120 match each other, the server 110 may determine that the purchase signal is legitimate. Also, the user terminal 130 may perform a step of transmitting payment information for a purchase signal for a purchase object to the server 110 .

When it is determined that the purchase signal is valid, the server 110 may perform a step of storing the identification information of the purchase object and the identification information of the user terminal 130 in the user object list corresponding to the user's identification information. Thus, the user can electronically own the purchase object.

When it is determined that the purchase signal is legitimate, the server may activate the purchase object until the expiration date of the purchase object included in the attributes of the purchase object. That is, the purchase object may have a deadline. The time limit may be infinite. However, the deadline may be finite. When the deadline has elapsed, the server 110 may delete the identification information of the purchased object from the user object list. Also, the server 110 may determine the purchase object as a virtual object of interest. The server 110 may store the virtual object of interest as log information. Also, the server 110 may determine a virtual object of interest as a virtual object having a high preference. The server 1100 may transmit the virtual object of interest to the manager terminal 120 so that the manager implements a real object corresponding to the virtual object of interest in the real world.

The user terminal 130 may perform step 332 of displaying at least one of virtual characters, virtual spaces, and virtual objects on the display. At this time, the user terminal 130 may perform a step of displaying the activated purchase object. That is, the virtual object purchased by the user may be displayed in the virtual space. Conversely, virtual objects not purchased by the user may not be displayed in the virtual space, or only a translucent outline may be displayed.

More specifically, the purchase object may be a virtual object in the shape of a roof tile of a temple. When a user purchases a tile through the above process, the tile purchased by the user may be displayed as a virtual object as part of a temple building in the virtual space. When the user or other users click (touch) a tile, which is a virtual object, using their terminals, buyer information of the virtual object may be displayed on the display. For example, the buyer information may be the buyer's name and wish message. Through this, as users purchase roof tiles, which are virtual objects, the temple building in the virtual space can be completed. Therefore, participation of users can be induced. In addition, users can feel a sense of accomplishment by seeing the process of building a building being completed in a virtual space with their contributions, and can feel a sense of satisfaction because other users can confirm their contributions.

Also, the purchase object may be a virtual object in the shape of a roof tile of a temple. When a user purchases a tile through the above process, the tile purchased by the user may be displayed as a virtual object as part of a temple building in the virtual space. When the user or other users click (touch) a tile, which is a virtual object, using their terminals, buyer information of the virtual object may be displayed on the display. For example, the buyer information may be the buyer's name and wish message. Through this, as users purchase roof tiles, which are virtual objects, the temple building in the virtual space can be completed. Therefore, participation of users can be induced.

Although the above has been described based on virtual objects, the same explanation may be possible for virtual spaces. More specifically, the user terminal 130 transmits a purchase signal for a purchase space included in a plurality of candidate virtual spaces stored in the server 110, user identification information, and user terminal identification information to the server 110. can be performed. The purchase signal for the purchase space may include identification information for the purchase space. When the user purchases the purchase space, the server 110 may control the user terminal 130 to display the purchase space. The server 110 may control the virtual character to move in the virtual space. Also, the user terminal 130 may control to place at least one object included in the user object list in the purchase space.
