Description

Implementation method of real-time flash avatar with natural movement like real world {Method for realizing a realtime flash avata}

The present invention relates to the field of avatar. More specifically, the avatar movie clip is shared library, which significantly reduces the time of newly downloaded when adding, modifying, or deleting elements, and at the same time, smooths the movement of the avatar and changes the background. Natural transitions, such as the real world, that let the user feel the realism and satisfaction as the avatar moves around freely moving on the screen in real time through transitions such as the camera's viewpoint change over the scene rather than the transition. The present invention relates to a method for implementing a real-time flash avatar.

In the past, netizens were fascinated by the anonymity of cyberspace, but now they felt the desire to express themselves, and avatars were created to satisfy both.

Avatar refers to an incarnation and an incarnation, and refers to an animated character that takes the place of a user in cyberspace. Originally, Avatar is a compound word of Sanskrit Ava which means to go down and pass, and Terr which means to go down and land. It refers to the incarnation of God who descended to the land in ancient India. They pointed to graphic icons that represent themselves, such as in chats. In other words, the avatar is a virtual body representing itself in a graphic-oriented virtual society, connecting the real world and the virtual space, and exists in the middle of anonymity and blindness.

Currently, the above-mentioned avatars are used in cyber shopping malls, virtual education, virtual offices, etc. in addition to chatting and online games. Recently, the most popular area for avatars is the online chat service, and chat services using avatars such as icon chat and 3D graphic chat have been introduced and used.

Traditional avatars are mostly two-dimensional pictures, and avatars appearing in mud games and online chats are the most basic. The three-dimensional avatar has appeared to complement the problem of the lack of reality of the two-dimensional avatar, and the three-dimensional avatar character has an advantage of having a three-dimensional feeling and a sense of reality.

In addition, most games and chat services usually provide a combination of a few characters or provide an already completed avatar.However, as graphic technology is improved, the character ID is not used by ready-made ones made by service providers. Like this, users have their own avatars that can create their own unique avatar. For example, "Avatar Editing Method in Avatar Editing System" of Korean Patent Application Publication No. 2000-27233 (published: May 15, 2000) includes a new avatar by selecting and combining a desired avatar in the avatar editing system. A technique for editing an avatar for editing is disclosed.

However, the avatars provided on the web browser face the inherent limitations of the web browser, and the user feels like the real world by showing only a simple movement even if there is no movement or movement in using the avatar. There was no problem at all.

In order to solve such a problem, a method of implementing an avatar using flash has been proposed. For example, "Dynamic Avatar Generation Method" of Korean Patent Application Publication No. 2002-70754 (published: September 11, 2002) adds real-time Hangul implementation and user's file control function to produce flash files. A technology for generating an interactive content by generating an avatar and inserting the avatar into an animation and a game is disclosed.

The flash is a file format for effectively delivering images, graphics, and sounds on the Internet, and was first proposed by Macromedia as a vector-based image technology as well as a conventional bitmap image processing technology. Has the same characteristics.

Firstly, Flash is designed for fast rendering of animations, interactive action buttons, and arbitrary bitmap images, which does not support anti-aliasing when rendering existing bitmap images. Beyond that, it supports on-screen anti-aliasing.

Secondly, Flash is organized in a tag format for extensibility with older versions and supports excellent extensibility.

Third, Flash is a compressed format file for delivery to clients almost indefinitely over a network called the Internet.

Fourth, Flash has the simplicity of being automatically played in the client's operating system by automatically downloading a very simple, small plug-in.

Fifth, Flash maintains file independence, and plug-ins do not require any extended font files or other files.

Sixth, flash works just as well with a myriad of hardware choices, such as many different types of monitors.

Seventh, Flash supports high speed rendering so there is no interruption in streaming.

However, in this method of implementing an avatar in Flash, the size of the avatar flash file (swf) becomes so large that it takes a long time to download a new element when adding, modifying, or deleting an element, and even if the avatar has movement, the scene changes. There is a problem in that even if there is no scene change, even if there is a scene change, the scene change is not smooth and the realism is decreased, so that there is a problem of not feeling any difference compared to the expression method on the web browser.

An object of the present invention is to solve such a conventional problem, and it is possible to implement in a basic configuration that does not require any component or hardware configuration on the server, and to add and modify an element by sharing a library of an avatar movie clip. In addition, it significantly reduces the time for new downloads when deleting, and smooths the avatar's movement, and enables the user to view the avatar in real time by changing the camera's view of the scene instead of changing the scene by momentary background changes. The present invention provides a method of implementing a real-time flash avatar having a natural movement like the real world, which makes the user feel a sense of reality and satisfaction such as moving around while moving freely on the screen.

And moving the avatar by changing the X coordinate value (S23), and driving the screen operation unit by checking the threshold values of the left and right X coordinates of the screen.

4 is a flowchart illustrating an operation of a screen operation unit of a method of implementing a real-time flash avatar having a natural motion as in the real world according to an embodiment of the present invention.

As shown in FIG. 4, the operation flow of the screen operation unit of the method of implementing a real-time flash avatar having a natural motion as in the real world according to an embodiment of the present invention includes displaying a current background screen (S30) and a screen. Step (S31) of checking whether the current screen is the last left or right screen by receiving a scroll command, changing the X coordinate value of the screen to scroll if the current screen is not the last left and right screen (S32), and the screen configuration Checking whether it is an infinite loop (S33); if the configuration of the screen is not an infinite loop, changing the movement of the avatar to stop and transferring control to the avatar operation unit (S34); and checking whether the current screen is the last left screen. In step S35, when the current screen is not the last left screen, the X coordinate value of the avatar is set to the left X coordinate limit value in the screen. Changing step (S36), changing the screen to the left last screen (S37), changing the X coordinate value of the avatar to the right X coordinate limit value in the screen when the current screen is the last left screen (S38), And changing the screen to the last right screen (S39).

According to the above configuration, the operation of the method of implementing the real-time flash avatar with natural motion as in the real world according to the embodiment of the present invention is as follows.

A flash with a static animation of one of the avatar's components, front, back, left and right, and a moving animation, and a simple animation of the avatar's head, head, eyes, nose, and mouth. After pre-producing the movie clip into a shared library, the movie clip is stored in the avatar information database 20.

Next, flash files, which are programmed and stored in the internal memory of the web server 10, as shown in FIGS. 2, 3, and 4, are stored from the user computer 40 to the Internet network 30. When a request is made to the web server 10 through the web server 10, the web server 10 loads each flash file swf including the avatar and distributes the flash files swf to the user computer 40 through the internet network 30.

The flash file swf includes an avatar, a background screen (screen), and a flash file for controlling the avatar / background screen, and also includes avatar motion variables (left, right, and stop), a screen scrolling variable, and a screen. Left and right limit constants exist.

Next, the web server 10 extracts the information of the component of the user's avatar stored in the member information database 20, and stores the information in the empty movie clip inside the avatar flash file swf. The avatar is formed by loading a flash movie clip of each component of the user's avatar from the shared library loaded on the computer 40.

Next, when the avatar left / right movement command is input (S10), the avatar / screen controller assigns a left / right value to the avatar left / right motion variable of the root level (S12).

The avatar action movie clip at the root level of the avatar operation unit continuously checks the variable in the event handler (enterFrame) (S21), executes the left / right movement of the avatar (S22), and simultaneously executes the X coordinate of the avatar movie clip. By moving the avatar movie clip to the left / right by changing the (S23), it is checked whether the X coordinate of the current avatar movie clip is equal to the left / right limit X coordinate of the screen (S24).

When the X coordinate of the avatar movie clip is equal to the left and right limit X coordinates of the screen, the screen operation unit checks whether the current screen is the left and right last screen (S31), and if the current screen is not the last left and right screen, the X coordinate of the screen Move to scroll (S32). Next, it is checked whether the screen configuration is an infinite loop (S33). If the screen configuration is an infinite loop, it is checked whether the current screen is the last left screen (S35). Replace the screen with the right X coordinate limit in the screen (S38), replace the screen with the last right screen (S39), and if the current screen is not the last left screen but the last right screen, replace the avatar's X coordinates within the screen. While replacing the left X coordinate limit value (S36), the screen is replaced by the last left screen (S37), thereby representing an infinite loop scene of the background screen (screen).

As described above, when the avatar is moving, the avatar flash file (swf) combines the elements of the avatar by bringing the user's avatar database information consisting of a flash action script that sets the appearance and movement using the shared library in real time. By showing it, you can control the front, back, left, right, stop, and natural movements, and create a smooth scene by scrolling the screen movie clip.

Therefore, the user feels the realism and satisfaction that the avatar, which is his alter ego, visits the site directly through the scene change such as the viewpoint change of the camera for the scene as shown in FIGS. .

On the other hand, when the user selects each element of the avatar in the flash site to modify its appearance, the web server 10 changes the appearance of the user's avatar in real time, so as to have the front and rear, left, right, left and right motions and movements accordingly. In addition, the avatar moves in a desired direction or a specific place on the screen, so that the avatar shows a realistic natural appearance.

As described in the above embodiments, the present invention provides a shared library of elements of the avatar movie clip, which significantly reduces the time of newly downloading when adding, modifying, or deleting elements, and naturally moves the avatar. Instead of changing the scene by changing the scene, such as changing the camera's viewpoint to the scene, the user can feel the realism and satisfaction as the avatar moves around while moving freely on the screen in real time.

Thus, on the service provider side, it is possible to develop and provide various contents (games, virtual cities, shopping malls) with more realism to users without using the existing infrastructure without changing the environment. You will be able to access various sites.
