Description

An automatic logging method that allows user to check the time of event occurrence on the metaverse platform}

The present invention relates to an automatic logging method that enables checking the time of occurrence of an event in the metaverse platform.

Virtual reality spectator mode game viewing service technology is Korean Patent Publication No. 10-2018-0130270, technology that separates and expresses virtual reality associations from multiple viewpoints is domestic patent registration No. 10-1855345, virtual reality conference service technology is registered domestic patent It is known as No. 10-2292606, but there is no known logging method that allows checking the time of event occurrence in the metaverse that forms virtual reality.

So far, social media platforms have been limited to open Web 2.0-based communication tools that allow individuals to interact with each other by sharing and consuming experiences, opinions, and information in the real world.

In addition, the social logging method in SNS is mainly related to fragmentary logging through pictures or videos, and there is no known logging method that finds the occurrence of an event by text file name and reproduces it on Unreal Engine.

The present invention is to solve this problem, and the object of the present invention is to perform lifelogging of events occurring within the metaverse 3D open world as a rendering engine-based data set, and to list the file names as text on the main server platform Provided on the above, it is intended to provide an automatic logging method that allows the user to check the event occurrence time in the metaverse platform that allows the user to check the occurrence of the event at the desired place and time in 3D status on Unreal Engine by selecting the text file name.

Another object of the present invention is to divide and select events occurring in the metaverse 3D open world into first-person mode, third-person mode, and spectator mode according to the camera position, calculate the visual and audible distance of the avatar according to the mode, , Life logging is limited within the calculated range and saved as a text file in the content delivery network (CDN) of the crowd function, so that logging data can be reduced and the storage device can be reduced. It is intended to provide a logging method.

The purpose of the present invention is to perform lifelogging of events that occur in the metaverse 3D open world with a rendering engine-based data set, but at the time of lifelogging, use the NFT blockchain method to make it possible to provide ownership to individual users. It is intended to provide an automatic logging method that enables checking the event occurrence time on the bus platform.

Another object of the present invention is to share life experiences, opinions, and information through an avatar, a virtual ego, in a 3D digital-based virtual space, and to 'decentralize' all records through blockchain-based technology, thereby giving digital ownership to individuals. so that it can be distributed to

Another object of the present invention is to provide a new social experience by building a transparent and healthy ecosystem in which users themselves can have the sovereignty of true data by allowing users to directly participate in the production of new content and service operation.

For this purpose, the present invention provides a platform 100 that provides an open world 500 based on Unreal Engine, and provides a user's avatar and generates an event when a user signs up as a rendering engine-based data set with an extension (json) in the text file name. A main server 200 that performs lifelogging recorded in *.json files in real time and turns the recorded data into a block chain in the NFT server 230 when necessary;

A user 300 joining the main server 200 as a member,

In the virtual space provided by the main server 200, the lifelogging record data in the form of *.json with the name of a text file containing the occurrence of events within the recording radius centered on the user avatar is NFT blockchained through IPFS (Interplanetary File System). It forms a system with a blockchain server 400 that provides it to the blockchain market;

Providing a platform that provides selectable events of avatars and objects in the open world provided by the main server 200 through the platform 100 by time, by camera position, 1st person mode, 3rd person mode and spectator mode Process (S10);

After a user visits the main server 200 and creates an avatar, set the recording radius of the visible and audible distance from the avatar position to the corresponding setting space of the main server by time, by camera position, 1st person mode, 3rd person mode and observer mode Avatar visible and audible distance setting process (S20);

The 3D space corresponding to the setting space and the events that occur in the 3D space by time, camera position, 1st person mode, 3rd person mode, and observer mode Selected datasets as text file name *.json file as lifelogging record data Life logging process to store in the main server 200 (S30);

It is possible to check the time of event occurrence on the metaverse platform, characterized by sequentially performing the NFT blockchain process (S40) of storing the life-logging data set in the NFT server 230 to NFT blockchain to provide ownership to individuals. It is intended to provide an automatic logging method that allows

As described above, the present invention performs lifelogging of events that occur in the metaverse 3D open world as a rendering engine-based data set, and provides them on the platform as a list of file names in text on the main server, so that the user can place the desired location. If you select the text file name of the event occurrence at time and time, you can check the event occurrence time on the metaverse platform that enables you to check the 3D state on Unreal Engine.

The present invention calculates the visual and audible distance centered on the avatar for events occurring in the metaverse 3D open world as a recording radius, and selects the camera in first-person, third-person, and observer modes within the calculated range for lifelogging However, the text file name is saved as a *.json file, and playback is played back in Unreal Engine, so the logging data can be reduced to reduce the storage device.

The present invention performs lifelogging of events occurring in the metaverse 3D open world with a rendering engine-based data set, but makes it possible to provide ownership to individual users by converting them into NFT blockchains using the NFT blockchain method during lifelogging.

The present invention shares life experiences, opinions, and information through avatars, virtual egos, in a 3D digital-based virtual space, and distributes digital ownership to individuals by decentralizing all records through blockchain-based technology. do.

By 'centralizing', it allows digital ownership to be distributed among individuals.

In addition, by allowing users to directly participate in the production of new content and service operation, it provides a new social experience by establishing a transparent and healthy ecosystem in which users can have true sovereignty over data.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Prior to the explanation, the terms used are summarized.

1. NFTs

It means 'Non-Fungible Token' and refers to a token that represents a digital asset with scarcity. NFTs utilize block chain technology, but unlike existing virtual assets, they are characterized by the fact that they are not interchangeable because they give digital assets a separate and unique recognition value.

It refers to virtual assets that cannot be replaced with other tokens on the blockchain. It is a means of digitally tokenizing existing assets such as games, art, and real estate by clarifying asset ownership. Since NFTs are based on blockchain, all relevant information such as ownership and sales history is stored in the blockchain, so the original issuer can be checked at any time, making counterfeiting impossible. In addition, while virtual assets such as existing cryptocurrencies have the same conditions depending on the issuer, NFTs contain a separate and unique recognition value, so they are not interchangeable. For example, the price per bit coin is the same, but when NFT is applied, one coin has a separate recognition value that cannot be replaced with other coins.

2. Metaverse [ Metaverse ]

It is a compound word of ‘Universe’, which means the real world, and ‘Meta’, which means ‘processing and abstraction’, and means a three-dimensional virtual world. In the metaverse, UGC (User Generated Content) created by users of the virtual world is distributed as a product and is distributed through virtual currency. As the popularity of Second Life, created by Linden Lab, an American IT venture company, is increasing, interest in metaverse is growing.

The metaverse world has been expressed in the word virtual reality, but now the word metaverse is mainly used as a term for an advanced concept. The term originally came from Neil Stephenson's 1992 novel Snow Crash.

3. Lifelogging

Automatically record all the information that an individual sees, hears, meets, and feels while living. A service that allows you to upload materials to your website regardless of location and time. Cyworld and Twitter, which have recently been in the limelight among young people, all fall under lifelogging.

4. Open World [ Open World ]

It refers to a game with almost no restrictions on play based on a high degree of freedom.

‘Open World’, along with ‘Sand Box’, refers to games with a high degree of freedom. Unlike games that force a linear story and movement route, it is also used as a term that refers to a game method that guarantees a non-linear story and free movement.

A representative example of an open world game is an online game, among which MMORPG (Massive Multy Online Role Playing Game). MMORPG has no restrictions on moving from region to region or desired place. In other words, the open world is defined as a system that sets the entire world as one space, removes the basic spatial restrictions, and guarantees a degree of freedom.

Most MMORPGs set the open world as the basic design of the game. To this end, a land scape to express the vast land and a seamless technology that does not require separate loading when moving the area are needed. Separate loading during movement is a representative factor that hinders the user's sense of immersion, so the open world in online games is sometimes referred to as a 'seamless world' with no boundaries between regions in online games.

5. Unreal Engine[ Unreal Engine ]

In order to make a work of art or creation, you need materials for it. At this time, it will be easier to create creations if you inform us of the necessary materials and how to use them in advance. Game engines play a similar role. A game engine is a collection of software, tools, and functions that are frequently used in games. With game engines, anyone can now develop high-level games quickly and easily. Recently, the most popular game engine in the game industry is 'Unreal Engine'. Unreal Engine is a technology created by a game developer called Epic Games. Epic Games started as Potomac Computer Systems in 1991, and developed a video game called 'ZZT' at the time. A year later, in 1992, Potomac Computer Systems changed its name to Epic MegaGames, Inc., and released a variety of games. The game that came out at that time was 'Unreal', and the core technology used in 'Unreal' was 'Unreal Engine'. ‘Unreal’ was a 3D-based First Person Shooter (FPS), and was already famous for its high technology at the time.

6. Log [Log, Rogue]

It is a record that leaves game play information over time in computers, servers, etc. The log is the user's information in the online game. This is because it is necessary to record activities so that we can respond quickly when problems such as bugs, hacking, or item recovery occur in the future. Logs are also important when disputes between users occur. Therefore, in most online games, various actions such as purchasing items, acquiring experience points, and chatting by users connected to the server are recorded and saved.

7.IPFS (short for Interplanetary File System), which means distributed file system protocol. IPFS is a form of distributed peer-to-peer, and it appeared in the world in 2014 when Juan Benet published a paper on IPFS. Later, in the same year, Stanford, Harvard, MIT, IBM, etc. established a company called Protocol Labs (https://protocol.ai/) in the form of a consortium, and in the following year, in 2015, IPFS payment method FileCoin ( https://filecoin .io/) was released.

If existing HTTP accesses the location where data is stored, IPFS accesses the contents of specific data. IPFS Web is a new Web that solves and supplements the problems of the existing HTTP Web.

8.p2p is a two-way file transfer system that is not a client-server model that is carried out by a central server as we already know. Without a central server, computers become servers and clients, respectively, and connect to each other to send and receive files.

9. CDN (Contents Delivery Networks) are several geographically distributed server-type storage devices. It speeds up the delivery of web content by delivering it close to the user. Data centers around the world use caching, the process of temporarily storing copies of files. Thus, users can quickly access Internet content from a web-enabled device or browser via a nearby server. A CDN caches content such as web pages, images, and videos on a proxy server close to the user's physical location. This way, you can watch movies, download software, check your bank balance, post on social media, make purchases, and more, without having to wait for content to load. A CDN works like an ATM if you install ATMs in multiple locations so that users can withdraw money quickly and efficiently.

10.UUID- As a Universally Unique IDentifier, UUID is a 128-bit number and is expressed in 32 hexadecimal digits. Here, hyphens are inserted every 8-4-4-4-12 characters to separate them into 5 groups. For example, 550e8400-e29b-41d4-a716-446655440000, and there are UUID versions 1, 3, 4, and 5.

11.Access Token- Token included in Authorization Header of HTTP Request.

In general, the JWT format is widely used. Since the token is at risk of loss, it usually has a valid time of 30 minutes to 1 hour.

12.ID Token-The user's ID, usually in JWT format.

The ID token must not have any authentication information or any refresh token information (audience information), and the user ID is simply used to identify the user. Source: https://winsmarts.com/access-tokens-and-refresh-tokens-and-id-tokens-5261bc26e8a2

If the present invention is defined, a log (a set of data available in a rendering engine), rather than a video recording, of playing through an avatar in a 3D digital-based virtual space (3D world created based on Unreal Engine) is saved as a text file name and reproduced. make it possible

In the present invention, the recording target stores a data set according to the reference time of all objects (avatars, animated objects, particles, etc.) that can move within a visible and audible distance (eg, a radius of 10 m) based on the user's avatar. . In the present invention, in particular, the camera is divided into a first-person mode in which a camera is taken from a selfie-like position, a third-person mode in which a third person shoots me, and a spectator mode in which the whole is filmed from a distance, and stored so that three-dimensional effect and various lifelogging are real, user It is characterized by providing images with individuality according to users even if they are in the same place, such as different shooting modes or combined shooting modes.

As the type of data stored in the present invention,

Avatar [Avatar information (nickname, basic information (index, characteristics, function, title), costume information (index, function), animation information (index, play time), transformation (3D-based X , Y, Z coordinates), event time according to reference time)],

Items (item information (index, function, characteristic) that the avatar is wearing, animation information (index, play time), transform, event time according to standard time),

Objects (information of objects that can move unrelated to the avatar existing within the recording radius, basic information (index, characteristics, function), animation information (index, play time), event time according to standard time),

Particles (information on all particles existing within the recording radius - basic information (index), animation information (index, play time), event time according to a reference time) may be mentioned.

The lifelogging method in the present invention performs file path setting, file reading, and json file conversion so that data is stored in a text name in a content delivery network (CDN) controlled by the main receiver.

The json file is very easy for computers to read and write. This makes it easy to store complex data such as lists of usernames without special analysis. The user is marked as user as shown in Table 1.

Create a users.json file in the ata folder and save it after leaving an empty array.

the full code is

const fs =require('fs');

const path =require('path');

const express =require("express");

const app = express();

app.use(express.urlencoded({extended:false}));

app.get('/currenttime',function(req, res){

res.send("<h1>"+new Date().toISOString()+"</h1>");

});

app.get('/',function(req, res){

res.send('<form action="/store-data" method="POST"><label>Your Name</label><input type="text" name="username"><button>submit</button ></form>');

});

app.post('/store-data',function(req, res){

const userName = req.body.username;

const filePath = path.join(__dirname,'data','users.json');

const fileData = fs.readFileSync(filePath);

const names = JSON.parse(fileData);

names. push(userName);

fs.writeFileSync(filePath, JSON.stringify(names));

res.send('<h1>Username saved</h1>');

});

app. listen(3000);

const fs =require('fs');

Specifically, it reads the array in the file -> gets the data entered by the user in the form -> inserts the data into the array and overwrites the file to update it.

To open the users.json file and add data to its array, we use a package called fs (file system).

When setting the file path

const path =require('path');

.

.

.

fs.writeFileSync(filePath, JSON.stringify(names));

You can write to a file using the writeFileSync method of the fs package. The path of the file and the file to be updated must be given as parameters of this. To easily extract a path that works in all operating systems, use the path package.

const filePath = path.join(__dirname,'data','users.json');

The join method of Path joins the various parts of a file's path description. In this case, the path must be an absolute path. Therefore, at first we use a JavaScript variable called ‘__dirname’. This is a built-in variable that holds the absolute path to the project path. Since there is a user.json file in the current data folder, pass these two as the remaining parameters.

Now, to extract that data from a file, you must first read the file, save and update the data, and then overwrite the file with this updated data.

read file

const fileData = fs.readFileSync(filePath);

To read a file, use the readFileSync method of the fs package.

A file path is given as a parameter. What you read in this way is raw text data, not JavaScript objects. The array in users.json is read as text. Therefore, the array read as text must be converted to a js object to insert data.

json file conversion

const names = JSON.parse(fileData);

To convert to JavaScript object, use JSON object of node js. This object has parse and stringify methods, here we use parse. parse converts text contained in a json file format into raw JavaScript objects or arrays.

names. push(userName);

Now put the userName constant, which is the data entered by the push method, into the converted array. You can pass the converted array as a parameter to the writeFileSync method... Since this also accepts raw text, we need to convert the JavaScript object to raw text. At this time, use the stringify method of the JSON object.

fs.writeFileSync(filePath, JSON.stringify(names));

Now, after opening the server and entering anything in the form, if you look at the array of users.json file, the entered data is saved as shown in Table 2.

The storage method in the present invention is as follows.

Automatic saving: From the start of play to the time limit, the data within the recording radius is saved in the form of a file according to the standard time, and from the time limit exceeded, the data is deleted from the start time in proportion to the time exceeded.

Manual Save: Saves the data within the recording radius from the time of the user's save event to the time limit in the form of a file according to the standard time.

Event storage: When an event set in the app occurs, the data within the recording radius from that point to the time limit is saved in the form of a file according to the standard time.

The regeneration method in the present invention is as follows.

Playback method: After the rendering engine is executed, all objects are rendered and animations are played over time based on the recorded data stored.

Sharing method: The user saves the recorded data in the form of a file on a device (user computer or mobile device) and uploads it to the cloud (content delivery network; CDN) provided by the main server, and the main server sends the uploaded cloud data to the user upon request convey

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the present invention, the occurrence of events within the recording radius centered on the avatar is all movable objects (avatars and animated movement of objects, particles, etc.). In addition, to provide first-person shooting mode, third-person shooting mode, and spectator shooting mode centered on the avatar at the same time, the video is provided from the perspective of the camera viewed from the position of the observer. Provides lifelogging, in which the composition of the video changes according to the recording radius even in the recording radius.

As shown in FIGS. 1 to 4, the present invention provides a platform 100 that provides an Unreal engine-based open world 500, and provides a user's avatar and generates an event when a user signs up for a membership using a rendering engine-based data set. The main server 200, which performs lifelogging in real time by recording the text file name as a *.json file with the extension (json) and converts the recorded data into a block chain in the NFT server 230 when necessary,

A user 300 joining the main server 200 as a member,

In the virtual space provided by the main server 200, the lifelogging record data in the form of *.json with the name of a text file containing the occurrence of events within the recording radius centered on the user avatar is NFT blockchained through IPFS (Interplanetary File System). The system is configured with a block chain server 400 that provides the block chain market.

The main server 200 in the present invention includes an authentication server 210, a web server 220, an NFT server 230, and a game server 240.

The authentication server 210 authenticates login of a user ID using a universally unique IDentifier (UUID) and an access token for authentication.

The web server 220 provides a virtual space, creates a user's avatar, and creates a playlist in the virtual space.

The NFT server 230 stores the event data stored in the web server 220 as a *.json file in the form of a text file name with an extension (json), as shown in FIGS. Network), NFT blockchainizes, and blockchainized event data is stored as a distributed file system protocol (IPFS; Interplanetary File System). That is, what is stored in the content delivery network (CDN) is simple data, and what is stored in the distributed file system protocol (IPFS; Interplanetary File System) means decentralized data that can be owned and sold by individuals.

As shown in FIG. 2, the operation of this system provides the user's avatar provided by the web server 220 to be provided by the platform 100 and an object within the recording radius to the virtual space, and the recording radius based on the avatar at the time of event occurrence Store the object state in the database (Redis DB), store it in the form of text file name *.json in the NFT server 230 in the content delivery network (CDN; Contents Delivery Network) storage device, turn it into a NFT block chain , Distribution of digital ownership by decentralization by storing block chained event data as a distributed file system protocol (IPFS; Interplanetary File System).

In the main server 200, after logging in through the authentication server 210 of the user, within the open world provided through the platform 100, the occurrence of events of avatars and objects provided by the web server 220 can be distinguished by time. The platform providing process (S10) is performed as shown in FIG.

The main server 200 performs an avatar visible and audible distance setting process (S20) of setting the visual and audible distance circular circumference at the avatar location as a setting space in the main server after the user visits and creates the user's avatar.

The 3D space corresponding to the setting space can be provided by selecting a first-person mode that shows in the form of a selfie, a third-person mode that takes a picture of the user by a third person, and an observer mode that shows the whole. A lifelogging process (S30) of creating a *.json file with a text file name for an event occurring in the 3D space by standard time and storing it in a content delivery network (CDN) designated by the main server 200 as lifelogging recorded data (S30) do

The elements for data set are 1) Avatar [Avatar information (nickname, basic information (index, characteristics, function, title) of all users existing within the recording radius, costume information (index, function), animation information (index, play time) ), transform (3D-based X, Y, Z coordinates), event time based on reference time)] information,

2) Item (item information index, function, and characteristic of the avatar being worn), animation information (index, play time), transform, event time according to standard time) information,

3) Objects (information of objects that can move unrelated to the avatar existing within the recording radius, basic information (index, characteristics, function), animation information (index, play time), event time according to standard time) information,

4) Particle information (all particle information existing within the recording radius - basic information (index), animation information (index, play time), event time according to the reference time) information is included. This is to enable data sorting based on temporal sorting and place coordinates.

Specifically, the *.json file for data set in the present invention can be exemplified in the following form. //The following is an explanation.

In addition, if only character (avatar) 1 of the characters is exemplified, it is as follows.

In the lifelogging process (S30) of performing lifelogging with such a *.json file, the lifelogging data set is stored in the content delivery network (CDN), and when NFT is requested by the user of the main server 200, the NFT server At (230), the NFT block chain process (S40) of storing the ownership so that it can be provided to each individual by turning it into a NFT block chain is sequentially performed.

Following the lifelogging process (S30) or the NFT blockchain process (S40), the main server 200 lists the text file names stored in the lifelogging process (S30) or the NFT blockchain process (S40) on the platform 100. List up process (S50) to provide to the main screen;

When the list-up text file name is clicked (selected), the main server 200 uploads the data of the corresponding *.json file stored in the content delivery network (CDN) (S60);

A reproduction process (S70) of reproducing (replaying) the uploaded content delivery network (CDN) data through the Unreal engine in the main server 200 is further performed.

An example of the open world 500 includes a central plaza 510, several roads 520 extending from the central plaza, and spaces 530 distributed between the roads, as shown in FIG.

The main server 200 sets the location of each space 530 by changing the position of the camera to implement the first-person mode, third-person mode, and spectator mode, and the two-dimensional coordinates (x, y) address and height coordinates for each location. Divide each into a three-dimensional space of (z),

In the avatar visible and audible distance setting process (S20), three-dimensional space addresses corresponding to the visual and audible distance setting space of the avatar are set for each camera mode (first-person mode, third-person mode, observer mode) as a recording radius, as shown in FIG. can be exemplified.

An example of the open world 500 includes a central plaza 510, several roads 520 extending from the central plaza 510, and spaces 530 distributed between the roads 520,

The main server 200 divides the location of each space 530 into a 2-dimensional coordinate (x, y) address and a 3-dimensional space of height coordinates (z),

In the life logging process (S30), the 3D spatial addresses of the recording radius corresponding to the visual and audible distance setting space of the avatar in the 3D space, the event occurrence time, and the camera mode that selects events that occur in each of the 3D spatial addresses Each data is collected and stored in a content delivery network (CDN) designated by the main server 200.

The method of reproducing the stored data in this way is to select a text file listed on the platform of the main server 200, execute the rendering engine in the web server 220, and then transfer the stored recorded data to all objects in the database (DB) in time. Depending on the flow, the data stored separately is selected, and the rendering and animation at the set time and place (location) of the data are played on Unreal Engine. Since the reproduction method itself is a known technology, a detailed description thereof will be omitted.

In the present invention, the recorded data can be block-chained in the NFT server 230 to claim digital ownership and can be shared only with authorized persons. In this case, the user stores the recorded data in the form of a file on a device (user computer or mobile device) and uploads it to the cloud provided by the main server 200, and the main server 200 transmits the uploaded cloud data upon user request. do.

The main server 200 converts the location of each space 530 into a 2D coordinate address (x, y) and a 3D space of height coordinates (z) by time, by camera position, in 1st person mode, in 3rd person mode, and by spectators. classified by mode,
The process of setting the visual and audible distance of the avatar (S20) is to set three-dimensional space addresses for each mode corresponding to the visual and audible distance setting space of the corresponding avatar for each time, camera position, first person mode, third person mode and spectator mode as a recording radius An automatic logging method that allows checking the time of event occurrence in the metaverse platform, characterized in that.
In paragraph 1,
The offworld 500 includes a central plaza 510, several roads 520 extending from the central plaza 510, and spaces 530 distributed between the roads 520,
The main server 200 divides the location of each space 530 into a 2-dimensional coordinate (x, y) address and a 3-dimensional space of height coordinates (z),
The life logging process (S30) collects data of 3D spatial addresses of a recording radius corresponding to the visual and audible distance setting space of the avatar in a 3D space, event occurrence time, and events occurring in each of the 3D spatial addresses An automatic logging method that enables checking the time of event occurrence in the metaverse platform, characterized in that for storing.
In paragraph 1,
Following the lifelogging process (S30) or the NFT blockchain process (S40), the main server 200 lists the text file names stored in the lifelogging process (S30) or the NFT blockchain process (S40) on the platform 100. List up process (S50) to provide;
When the list-up text file name is clicked, the main server 200 loads the data of the corresponding *.json file from the content delivery network (CDN) (S60);
Automatic logging that enables confirmation of the time of event occurrence in the metaverse platform, characterized in that further performing a playback process (S70) of reproducing the uploaded content delivery network (CDN) data through the Unreal engine in the main server 200 method.
