More specifically, when a textbook composed of text is inputted, a voice is generated and a cyber teacher lectures by a character whose facial expression or motion changes according to a word or a context. Save and provide this scene as a video, and as the video lecture progresses, the key points of the lecture will appear in writing format in a web document in order to obtain the same writing effect as in the actual classroom lecture. It is about a remote lecture method using Han Cyber Teacher, so that the contents of lectures can be changed immediately as the syllabus is changed without receiving the teacher.
현재의 학습 방법은 기록 매체의 발달로 문서 위주의 학습지나 문제지 방식에서 벗어나, 카세트 테잎, 비디오 테잎, 및 방송강의, CD-ROM 등을 이용하여 점차 발전되고 있다.The current learning method is gradually developed by using a cassette tape, a video tape, a broadcasting lecture, a CD-ROM, etc., due to the development of a recording medium.
최근에는, PC통신이나 인터넷을 이용하여 원거리에 떨어진 사람들 사이에서도 시간에 구애받지 않고 원격 학습이 이루어지고 있다. 이러한 원격 학습 시스템의 예로서 국내 특허출원번호 1999-4399호에는 PC통신을 통해서 학생과 선생님 사이에서 양방향 학습을 할 수 있는 양방향 교육 시스템과 그 제어방법에 관한 기술이 기재되어 있다.In recent years, distance learning has been carried out regardless of time even among people remotely using PC communication or the Internet. As an example of such a distance learning system, Korean Patent Application No. 1999-4399 describes a technology related to an interactive education system and a control method thereof, which enables a bidirectional learning between a student and a teacher through PC communication.
도 1은 종래 기술에 의한 원격강의 방법을 나타낸 흐름도이다.1 is a flowchart illustrating a method of remote lecture according to the prior art.
여기에 도시된 원격강의 방법은 먼저, 학생들이 학교에서의 학습내용 이외에 부가적으로 학습할 수 있도록 하는 소정의 교육내용이 기재된 학습지나 문제지를 인쇄하여 학생들에게 배포하고, 배포된 학습지나 문제지의 교육내용에 대해 설명하는 선생님의 모습과 육성을 비디오카메라와 마이크 등을 이용하여 녹화하고 이를 동영상으로 변환하여 데이터베이스를 구축한다. 그러면, 사용자들이 웹서버에 접속하여 데이터베이스에 저장된 동영상을 통해 선생님이 강의하는 모습을 듣게 된다.The distance teaching method shown here first prints and distributes a workbook or a questionnaire with a predetermined content to enable students to learn in addition to the content of the school, and distributes it to students. The teacher's appearance and upbringing about the contents are recorded using video cameras and microphones, and converted into videos to build a database. Then, users access the web server and hear the teacher lecture through the video stored in the database.
또한, 학습지 및 문제지를 웹서버에서 제공할 경우에는 직접 접속한 상태에서 학습하거나 프린터를 통해 출력하여 사용함으로써 학습지의 배포과정을 줄이기도 한다.In addition, when the workbook and the questionnaire are provided by the web server, the process of distributing the workbook may be reduced by learning from a directly connected state or by outputting through a printer.
이와 같이 학습지 및 문제지를 웹서버에서 제공할 경우 웹서버에 등록된 학습지 등을 변경할 경우 사용자들은 새롭게 변경된 문제지를 즉시 제공받을 수 있다.As described above, when the workbook and the questionnaire are provided by the web server, the user can immediately receive the newly changed questionnaire when the workbook registered in the web server is changed.
그러나, 새롭게 변경된 학습지를 강의하는 동영상의 경우 변경된 부분을 갱신하기 위해 선생님의 강의하는 모습을 다시 녹화하여야 한다.However, in the case of a video that lectures on a newly changed work sheet, the teacher's lecture must be recorded again to update the changed portion.
그런데, 동영상에서 강의하는 모습을 선생님이 강의하는 모습을 녹화하여 제공하기 때문에 변경된 학습지의 일부분을 녹화하기 위해 선생님을 초청하기에는 많은 비용이 소요되어 학습지 등의 교안이 변경될 경우 즉시 변경되지 않는 문제점이 있다.However, because it provides a video recording of the teacher lectures, it takes a lot of money to invite the teacher to record a portion of the changed study paper, so that if the teaching materials, such as the study paper is changed, it does not change immediately. have.
또한, 학습지의 일부분이 변경되었을 경우라도 전과정을 모두 다시 녹화하여 동영상을 다시 제작할 경우 동일한 부분까지 재작업을 해야하기 때문에 필요없는 시간이 소요되는 문제점이 있다.In addition, even if a part of the study paper is changed, when the entire process is re-recorded to re-create the video, it is necessary to rework up to the same part, which requires unnecessary time.
한편, 선생님이 강의하는 모습을 비디오카메라 등으로 녹화하여 동영상을 제작할 경우 해상도에 따라 파일크기가 커지게 되어 통신상태에 많은 영향을 받게 되는 문제점이 있다.On the other hand, when a teacher makes a video by recording a video with a video camera, etc., there is a problem that the file size becomes large according to the resolution and is greatly affected by the communication state.
본 발명은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 텍스트로 이루어진 교안을 입력하면 음성이 생성이 되어 사이버 캐릭터에 의해 사이버 선생님이 강의를 진행하도록 하고 이 장면을 동영상으로 저장하여 제공함으로써 강의를 담당하는 선생님의 수급없이 교안이 변경됨에 따라 즉각적으로강의내용을 변경할 수 있을 뿐만 아니라 동영상의 파일의 용량을 적게 하여 인터넷을 통한 빠른 서비스 및 다운로드 서비스가 이루어질 수 있도록 한 사이버 선생님을 이용한 원격강의 방법을 제공함에 있다.The present invention has been created to solve the above problems, the object of the present invention is that the voice is generated when the teaching text consisting of the text is generated by the cyber teacher lectures by the cyber character and save the scene as a video By providing and providing a teacher, the cyber teacher can change the contents of the lecture immediately as the syllabus is changed without receiving the teacher who is in charge of the lecture. To provide a remote lecture method used.
또한, 동영상 강의가 진행됨에 따라 해당되는 강의의 요점이 판서형식으로 웹문서상에 차례대로 나타나도록 하거나 미리 웹문서상에 나타나있는 해당 강의 요점 부분에 표시를 하여 실제 교실 강의에서와 같은 판서효과를 얻을 수 있도록 한 사이버 선생님을 이용한 원격 강의 방법을 제공함에 있다.In addition, as the video lecture proceeds, the main points of the corresponding lectures can be shown in the writing form in order in the web document, or by marking the main points of the lectures appearing in the web document in advance to obtain the same writing effect as in the actual classroom lecture.

여기에 도시된 바와 같이 먼저, 강의를 위한 학습지 및 교안 등의 교재를 기획하고 제작하게 된다(S10).As shown here, first, to plan and produce a textbook, such as learning papers and lesson plans for the lecture (S10).
이후, 교안을 설명할 사이버 선생님의 캐릭터를 설정한다(S20). 그리고, 사이버 선생님으로 하여금 교안의 텍스트를 TTS(Text To Sound)기술을 적용하여 음성으로 읽도록 한다(S30). 그런 다음 출력되는 음성에 따라 사이버 선생님의 입모양이나 표정을 단어나 문맥에 맞추어 변화시킨다(S40). 이렇게 텍스트 교안에 따라 사이버 선생님이 강의하는 모습을 동영상 파일로 저장하여 데이터베이스를 구축한다(S50).Then, the character of the cyber teacher to explain the teaching plan is set (S20). Then, the cyber teacher reads the text of the syllabus by voice by applying TTS (Text To Sound) technology (S30). Then, according to the output voice, the cyber teacher's mouth or facial expression is changed to match the word or context (S40). In this way, a database is stored by storing a video of a cyber teacher lectured according to the text teaching as a video file (S50).
그런 다음, 동영상 파일과 선생님이 강의하면서 판서하는 요점정리의 문서들의 진행이 일치하면서 웹상에서 표시될 수 있도록 원격강의를 위한 문서가 포함된 HTML이나 SGML이나 PDF의 파일형식으로 제작한다(S60).Then, the video file is produced in the file format of HTML, SGML or PDF including the document for the remote lecture so that the progress of the point-of-the-line document written by the teacher can be displayed on the web while being consistent (S60).
또는, 이미 문서에 요점정리의 내용이 표시되어 있는 상태에서는 동영상 강의가 진행됨에 따라 강의 내용과 일치하는 부분의 요점정리에 글자색을 변경하는등의 방법으로 표시할 수도 있다.Alternatively, when the content of the point theorem is already displayed in the document, as the video lecture progresses, the text color may be displayed in the point theorem of the portion corresponding to the content of the lesson.
이후 인터넷의 웹서버를 통해 제작된 동영상 파일과 웹문서를 제공함으로써 원격의 사용자가 접속하여 강의를 들을 수 있도록 웹서비스를 하게 된다(S70).After that, by providing a video file and a web document produced through a web server on the Internet, a web service is performed so that a remote user can access and listen to a lecture (S70).
한편, 동영상 파일의 크기가 작아서 사용자가 자신의 컴퓨터로 다운로드하여 강의를 들을 수 있도록 다운로드 서비스를 할 수도 있다.On the other hand, since the size of the video file is small, a download service can be provided so that the user can download to his computer to listen to the lecture.
위와 같이 TTS기술을 이용한 사이버 선생님을 통해 강의를 함으로써 교안의 일부가 변경될 경우에도 즉시 강의내용을 즉시 변경하여 제공할 수 있게 된다.By giving lectures through cyber teachers using TTS technology as described above, even if a part of the lesson plan is changed, the contents of the lecture can be changed immediately and provided.
상기한 바와 같이 본 발명은 텍스트로 이루어진 교안을 입력하면 음성이 생성이 되어 단어나 문맥에 따라 표정이나 동작이 변화되는 캐릭터에 의한 사이버 선생님이 강의를 진행하도록 하고 이 장면을 동영상으로 저장하여 제공함으로써 강의를 담당하는 선생님의 수급없이 교안이 변경됨에 따라 즉각적으로 강의내용을 변경할 수 있는 이점이 있다.As described above, in the present invention, a voice is generated by inputting a syllabus consisting of text, and a cyber teacher by a character whose facial expression or motion is changed according to a word or a context proceeds a lecture, and the scene is stored as a video and provided. As the syllabus is changed without receiving the teacher in charge of the lecture, there is an advantage that the contents of the lecture can be changed immediately.
또한, 동영상 강의가 진행됨에 따라 해당되는 강의의 요점이 판서형식으로 웹문서상에 차례대로 나타나도록 함으로써 실제 교실 강의에서와 같은 판서효과를 얻을 수 있는 이점이 있다.In addition, as the video lecture proceeds, the main points of the corresponding lectures appear in the writing form in order in the web document, so that the writing effect as in the actual classroom lecture can be obtained.
또한, 캐릭터에 의해 컴퓨터 내에서 처리되기 때문에 동영상 파일의 제작이 용이하며 동영상 파일의 용량이 적어 인터넷 등의 통신망을 통한 빠른 서비스가 이루어질 수 있는 이점이 있다.In addition, since the character is processed in a computer, it is easy to produce a video file, and the capacity of the video file is small, so that there is an advantage that a quick service through a communication network such as the Internet can be achieved.
