Abstract

PURPOSE: A method for creating a dynamic avatar is provided to make interactive contents by inserting the avatar created by a flash file into an animation and game. CONSTITUTION: When accessing an avatar creation page, a client automatically downloads, stores, and displays an avatar-flash file together with a shockwave plug-in. Also, the client selects every part of avatar components, changes the size and position value of every part, and transfers to a web server. The web server stores the values of every part to the DB fields corresponding to every part of the avatar components, loads a server component recreating a template file on a server memory, and creates the only avatar file of the client on the server memory by inputting variables of every part into the template file. After the web server creates the flash file containing the resumed avatar, the client shows and downloads the flash file through a web browser.

Description

{Method for generating dynamic avatar}

The present invention relates to a method for generating a dynamic avatar that allows a user to create a new multimedia object by selecting an object and to generate interactive web content desired by the user by creating an avatar of the user and inserting the same into a game or animation. More specifically, the present invention relates to a dynamic avatar generation method for changing an avatar's motion and facial expression as it progresses.

In general, Flash is a file format for effectively delivering images, graphics, and sound on the Internet. It was first proposed by Macromedia as a vector-based image-related technology as well as a conventional bitmap image processing technology. It was built on the same purpose.

First, it is designed for fast rendering of animations, interactive action buttons, and arbitrary bitmap images, which overcomes the disadvantage of not supporting anti-aliasing when rendering existing bitmap images. It supports anti-aliasing on the screen. Second, it is composed of tag format for extensibility with old version, and supports excellent extensibility. Thirdly, it is a compressed format file for delivery to clients almost infinitely through the network of the Internet. Fourthly, it downloads a very simple and small plug-in automatically, which implies the simplicity of being played automatically in the client's operating system. Fifth, as a file's independence, a plug-in doesn't require any extended font files or other files. Sixth, even a lot of hardware (for example, many monitors of different types and functions) works well on special hardware. Seventh, streaming speeds are not interrupted by supporting fast rendering.

Based on the unique advantages of the Flash file format, the flash technology currently used by more than 200 million people worldwide continues to grow and continues to grow. It is expected to gradually become a world standard of vector-based image file format.

The trend of the conventional flash generating technology and avatar generating technology will be described.

In the past, a flash generator required a user to purchase and produce a specific application when the user wanted to generate a flash (SWF) file. The flash file, which is produced once, is queried from a database because it is difficult to reproduce the source before compilation. A server program is needed to regenerate and combine media elements. It was developed as a server-based component to compensate for this. It is also one of the products sold by Macromedia. However, there are some problems. The first is that it does not support vectorization of 2byte characters, so it does not support other than ASCII characters and Japanese, and the second is a tool that allows users to directly control the generated files. There is a problem that is not provided.

Meanwhile, the avatar refers to a character that replaces the user in the virtual space, and the avatar generation refers to a character that combines body elements and functions selected by the user in response to the interactive request of the user.

However, the characteristics of the conventional avatar generation sites, because the avatar element is formed in the form of a bitmap, the image is destroyed when the avatar element is rotated, enlarged, reduced, etc., the image element generated during printing of the image Since it does not have the above information, it cannot be enlarged and printed, and it is impossible to give an attribute to each element of the body.

The present invention has been invented in view of the above-described circumstances, and in real-time Hangul implementation and the user's file control function are added to produce a flash file (swf file), while using this to create an avatar, and the avatar to animation and game An object of the present invention is to provide a method for generating a dynamic avatar that can insert and generate interactive content.

The present invention for achieving the above object is made as follows.

First, after accessing the server through membership authentication (subscription, login), the user generates a temporary avatar file (* .swt) for generating the avatar presented by the server (server component-ASP component or server side page-Java Servlet). Save the user's avatar file on the server.

In addition, temporary game temp files (* .swt) are stored in the server's repository through the generator so that avatars can be inserted into the game.

Flash files (* .swf) can be executed in the client's web browser through a plug-in based on ActiceX technology distributed by Macromedia.

The generator mentioned earlier is an application on the server. Based on the options selected by the user through this server component, the server reinterprets the swt file and outputs it as a swf file for the plug-in to interpret. This does not require the client to download like other server-client based ActiveX components. There is no inconvenience to install on server and download to client.

Temporary files (* .swt) are similar to swf files, but can accept variables inside the file. For example, if you have a variable named 'name', you can use the expression '{Name}' inside the file to accept the user's value.

Ex) You can pass the value of the variable in the form Sample.swt? Name = HelloWorld.

The generator finds a variable named Name in the Sample.swt file and enters HelloWorld to create a single swf file. Then, in the swf file, the format {Name} no longer exists, and the value entered by the user HelloWorld is placed.

Through this function, tens of thousands of temp files (swt) can be created to accept the user's variable values, allowing the user to input or select the desired variable to create and save the desired file.

According to the present invention, when a client accesses a web server that provides a dynamic avatar generation service, the member authentication step or member registration step is performed to store the input information in the member database, and the session value is given to the client. Joining the server to allow access to,

When a client identified as a member accesses an avatar creation page, the web browser automatically downloads the page and avatar-flash file and stores it in the client's storage space.The plug-in loads a flash file into memory on the client computer. Prepare and process the action button for setting the avatar by interpreting it and displaying it. Through the flash action button of the displayed screen, the client displays each element of the desired avatar (face, eyes, nose, mouth, head, glasses, decoration, and body). ) To create a desired avatar by changing the size and position value of each element and selecting the publish button after the client selects the avatar element and transmits it to the web server. Avatar element selection step,

After checking whether each element for avatar creation is delivered, the web server moves to the previous page of the client if the correct input value is not delivered, and transfers the received element values to the unique session value of the user when the correct input value is delivered. Storing each avatar component in a corresponding field of a database for a server component; loading a server component capable of regenerating a template file in server memory; and inputting a variable for each element in the template file. Generating an avatar file of the actual client only in the server memory, storing the file created on the memory as a physical file in the server storage space, and transmitting the file existing on the server to the client browser at the client's request. Avatar generation step of the server, the client When the web server accesses a page that enables the avatar to be inserted into the flash file and selects the flash, the web server reconstructs the object with the properties contained in the flash to generate the flash file with the avatar inserted into the client's storage space. It includes an avatar insertion step in a flash file that allows a client to view or download a flash file generated through a web browser by allowing a file path value to be transmitted to a third party such as a store or a mail receiver.

Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a server system constituting the present invention.

The server system according to the present invention is a web server that maintains a homepage and shows it according to a browser's request. The server system stores a avatar generation page and shows it according to a client's request. A web server 10 that downloads automatically to a web server, an application server that is typically associated with or works with a web server (HTTP server) that provides business logic to applications within a computer within a distributed network and has been modified according to the work requirements of the web server. Avatar-publishing server 12 used to provide a way to return a new web page to the user, as a plug-in that plays a file made of Flash, and can be used to interactively operate graphics, animations, sounds, and the like, For example, in the present invention Consists of the avatar file is stored in the data storage unit (16) generated by the information registered members related to Macromedia's Shockwave file storage section 14, the program is stored, a subscribed member.

FIG. 2 is a diagram illustrating a server / client network configuration according to the present invention, and illustrates a response of a server in response to a request of each client. In this case, the network between the server and the client is connected to the Internet network.

3 is a flowchart illustrating a method for generating a dynamic avatar according to the present invention.

The execution order of the flash file is as follows. In the following, the client is commonly used as a client web browser.

The client uses a web browser that uses an IP network to deliver a uniform resource locator (URL) to the web server.

Avatar generation service according to the present invention, in order to provide a service in the case of membership registration, after membership authentication, when a non-member client accesses the web server 10 through the URL of a web browser, the member consents to a series of member registration pages. In addition, enter the member information (including ID and password).

When the web server 10 receives the input information from the client to join as a member, the web server 10 checks whether the received information is duplicated with the ID of the existing subscriber and checks whether the user joins through real name.

If it is confirmed that the user can join, the member information (including ID and password) is input into the member information configuration field of the member database in the data storage unit 16.

In addition, the data storage unit 16, which is a storage space of the web server, creates a folder for the member's storage space through the member ID.

The session value is then given to the client. The session value is a variable that proves that a member is a member after authentication.

When the member authentication step is completed or it is confirmed that the member is a member, the client moves to the avatar creation page and performs the following avatar element selection step.

First, the Shockwave Plug-in (SwFlash.ocx) is automatically downloaded to the client and saved to the client. At this point, the downloaded plug-in does not need to be downloaded anymore (based on ActiveX control technology).

The client computer downloads the files and web pages to be played from the server computer and stores them in the temporary storage of the client computer.

To play, the client computer loads the files and pages stored in the temporary store into its memory.

At this time, the downloaded plug-in interprets this and displays it on the screen.

Here, the file refers to a swf (ShockWave File). When the client requests the page from the server, the server sends the page to the client, and the client web browser stores the page to be sent to the temporary storage. At this time, the swf file added as <Object> </ Object> is automatically saved in temporary storage by the client browser.

The following is an example of the format added to a web page.

<OBJECT classid = "clsid: D27CDB6E-AE6D-11cf-96B8-444553540000" codebase = "http://active.macromedia.com/flash2/cabs/swflash.cab#version=4,0,0,0" ID = main_movie WIDTH = 593 HEIGHT = 166> <PARAM NAME = movie VALUE = ”Addition.swf">

<PARAM NAME = quality VALUE = high>

<PARAM NAME = bgcolor VALUE = # FFFFFF>

<EMBED src = "additions.swf" quality = high bgcolor = # FFFFFF WIDTH = 593 HEIGHT = 166 TYPE = "application / x-shockwave-flash" PLUGINSPAGE = "http://www.macromedia.com/shockwave/download /index.cgi?P1_Prod_Version=ShockwaveFlash "> </ EMBED>

</ OBJECT>

You can add swf file to web page through the above format. The client web browser automatically recognizes the object and automatically downloads the file to the user's temporary repository. And

The codebase "http://active.macromedia.com/flash2/cabs/swflash.cab file is an ActiveX-based plug-in (ocx file). If this file does not exist on your client computer, download it as well." Interprets the additional file.swf file and runs it in the client web browser, which is automatically registered in the registry of the client computer in the file format application / x-shockwave-flash after download.

If there is a swf file added to the web page, the registered ocx file runs this swf file.

4 illustrates an example of a screen for selecting an avatar element by the client according to the above process. The avatar element includes body parts, and the client may select while changing the position and size of the avatar element. Whenever the avatar element is selected, the selected corresponding element is combined on the right side to complete the selection of the avatar element.

The following describes the procedure for creating and executing an avatar flash file on the client computer.

The client accesses the corresponding page of the web server 10 through the Internet.

The client stores the page and the avatar-flash file from the web server 10 in the storage space of the client (including the plug-in ActiveX control).

The plug-in loads the flash file into memory and interprets it.

Display on the client computer (preparing action button for client avatar setting).

The client selects each element of the desired avatar through the flash action button of the displayed screen.

Each element of the avatar selected by the client is composed of various parts of the body, and the horizontal, vertical, and position values can be changed.

When the client selects a publish button, each element value of the avatar selected by the client is transmitted to the web server 10 through the URL.

The following describes the avatar generation operation in the server.

When the web server 10 confirms that the publish button is selected after each element value of the avatar is selected by the client in the avatar generation step by the client, the web server 10 determines the respective elements for generating the avatar on the server side page. Check for the presence of element values. If the correct input value is not delivered, go to the previous page of the client.

In the web server 10, an avatar template file (* .Swt) for creating an avatar already exists. Looking at the configuration of the template file, the file for loading the corresponding element is a file. The file is designed to accept variable values for each element.

The web server 10 inputs the received element values into the corresponding fields of each avatar component of the database for the unique session value of the user.

After input, the server side page loads a server component that can recreate the template file in server memory.

Input the variables for each element in the template file to create the actual client's avatar file in server memory.

The file created on the memory is stored as a file in the data storage unit 16 which is a server storage space as an actual file.

Then, at the client's request, the file existing on the server is sent to the client browser.

The following describes the operation of inserting an avatar into a flash file.

When the client accesses the page of the web server 10 and selects the corresponding flash, the web server 10 reconfigures the object with the properties included in the flash. At this time, the client controls the selected object according to the timeline, so an animation is generated. The generated flash file is stored in the storage space of the client or the path value of the file is transmitted to a third party (mail receiver). The client can view the generated Flash file through the web browser or download it directly to the client.

5A illustrates an example in which an avatar is inserted into a game as described above, and the avatar 18 inserted into the game proceeds as the components of the body move according to the scenario and the user's operation of the game. FIG. 5B shows a scene in which the avatar 18 is inserted into an animation and moves according to a scenario.

As described above, since the avatar 18 is composed of a vector-based flash file, the avatar 18 may generate interactive content without aliasing even when inserted into a game or animation.

As described above, the present invention can generate and store an object or avatar desired by the user, and can express the emotion by attaching it to an e-mail using the same, and print and sell the product. You can also insert avatars into animations to change motions and facial expressions as you progress. Insert objects into music videos to change motions and facial expressions as you progress. Insert movies into parodys to change motions and facial expressions. I can do it. In addition, you can express your emotions with your own avatar when chatting with other users, insert them into the game, set them as the main characters or third parties of the game, and play the game automatically. Since it can be controlled, it has the advantage of showing more dynamic effects.
