Abstract
Description
The present invention relates to video lecture authoring, and more particularly, to a video lecture kiosk using a virtual 3D avatar and a method of authoring the same.
As information technology (IT) technology develops, e-learning, that is, learning methods using IT devices and the Internet, is becoming popular.
Educational broadcasts as well as educational video lectures have been widely distributed and used regardless of time and place.
In addition, instructional lectures are mainly produced in professional institutes or specialized educational broadcasting facilities, but general individuals or individual instructors also produce and distribute these educational contents.
Producing educational content requires producers, cinematographers, other staff, as well as various broadcasting equipments.
Therefore, the production of educational contents is difficult in the general public and small-scale institute facilities.
Meanwhile, such educational contents are produced by live-action images by cameras, but recently they are also produced by using animations or avatars instead of instructors.
However, in the case of contents using animations or avatars, it takes a lot of production cost and production time, which makes it difficult to produce the contents.
Particularly, in the case of a 3D avatar (3D avatar), the cost and time of the 3D avatar are rapidly increased because they are performed through a manual operation such as a flash. The 3D avatar on behalf of the instructor must generate the 3D avatar according to the voice, mouth shape, and gesture of the instructor, so that much effort needs to be made in order to express the movement of the 3D avatar in detail.
As described above, there is a need for a method for producing educational contents more easily and efficiently without lagging in recent trend of high-quality digital contents. And public and individual instructors need to be able to author educational contents more easily and at low cost.
It is an object of the present invention to provide a video lecture authoring kiosk using a virtual 3D avatar.
Another object of the present invention is to provide a video lecture authoring system using a virtual 3D avatar.
According to an aspect of the present invention, there is provided a video lecture authoring kiosk using a virtual 3D avatar comprising: a vertical support; A touch screen module attached to the top of the support; A motion sensor provided on a frame of the touch screen module and sensing movement of the user's mouth, mouth and facial muscles located in front of the touch screen module; A microphone disposed on a frame of the touch screen module and sensing a voice of a user located in front of the touch screen module; A motion sensor encoding a motion of a user sensed by the motion sensor, a motion of a mouth, a movement of a facial muscle, and a voice of a user sensed by the microphone to a virtual 3D avatar set in advance, module; And a video lecture authoring module for generating a video lecture file using the virtual 3D avatar matched by the motion sensor encoding module.
Here, the video lecture authoring module may be configured to display on the touch screen module in real time in order to allow the user to check the generated video lecture file in real time.
The video lecture authoring module is configured to generate a video lecture file composed of at least one of text, picture, chart, and photograph indicating the lecture contents of the user and a virtual 3D avatar .
And an upload module for uploading a video lecture file generated by the video lecture authoring module to a web server.
The motion sensor may include an inertia value sensor attached to each joint of the user and measuring and measuring a change in the inertia value according to the movement of the user.
And the animation lecture authoring module is configured such that the 3D virtual avatar is selected by the user for each video lecture file.
In addition, the touch screen module may be configured to be tilted up, down, left, and right toward the user according to the movement of the user.
According to another aspect of the present invention, there is provided a video lecture authoring system using a virtual 3D avatar, which detects motion, mouth motion, facial muscle movement and voice of a user located in front of a touch screen module, Mouth motion, facial muscle movement and voice are matched to a preset virtual 3D avatar, a video lecture file is generated using the matched virtual 3D avatar, and a generated video lecture file is generated Kiosk to upload (kiosk); A web server for storing a video lecture file uploaded by the kiosk and providing a downloaded video lecture file according to a download request; And a learner terminal for requesting download of a lecture file stored in the web server and downloading and displaying the lecture file from the web server.
At this time, And display the generated video lecture file on the touch screen module in real time so that the user can check the video lecture file in real time.
The kiosk may be configured to generate a video lecture file composed of at least one of a text, a picture, a diagram, and a photograph indicating the content of the user's lecture and the virtual 3D avatar.
The kiosk may be configured to detect movement of the user by measuring a change in inertial value using an inertial value sensor attached to each joint of the user.
The kiosk may be configured such that the 3D virtual avatar can be selected by the user for each video lecture file.
The touch screen module of the kiosk may be tilted up, down, left, and right toward the user according to the movement of the user.
According to the video lecture authoring kiosk and authoring system using the virtual 3D avatar as described above, the movement of the user is captured using the motion sensor of the kiosk, and the animation lecture file is generated by matching the user's motion with the virtual 3D avatar, It is effective to author video lecture.
It also has the effect of authoring high quality realistic video lectures with low cost and effort.
Therefore, it is possible to easily distribute video lectures to a small institute or a school, a private lecturer, and the general public by easily authoring and uploading the lecture on the web.
