Description

Moving-picture lecture system for allowing learner to note down lecture}

The present invention relates to a video lecture system, and more particularly, to a video lecture system that allows a learner to write using a key input unit and a handwriting input unit of a user terminal while taking an internet video lecture.

As the Internet develops rapidly, the information service industry using the Internet is increasing in many fields. In particular, with the expansion of high-speed communication networks, information infrastructure has spread, and internet education has emerged as an alternative to solve the problem of private education costs. This is because online lectures using the Internet are more flexible than the cost and time constraints of existing education systems, such as traditional university education, vocational education, seminars or organizational education by professional educational institutions.

That is, online lecturers can freely adjust the course time and pay less for lectures, but the learning effect is not lower than that of traditional educational institutions. Also, as an online lecture provider, the initial cost of developing and uploading an online education site to the Internet can be low, thereby providing users with various online courses.

However, the current online curriculum does not go beyond the form of simple information, learning materials, and presentation methods, as has been done in schools or schools in the past, and thus does not increase the efficiency of learning. In addition, the user's spontaneity, individuality and interaction has been a problem that can only play the role of replacing the existing textbooks or reference books on the Internet ignored.

As described above, the degree of learning through a book or simply transferring the contents of the book to the Internet has a disadvantage in that it is rather a cliché for the learners in the computer and internet era or not interested in learning.

In detail, the conventional lecture through the Internet is composed of two methods, a script method of writing with an electronic pen together with voice, and a simple video method consisting of only voice and video. There were many cases where learners didn't know about the part that the instructor passed without explanation, and there was a problem of losing interest in learning by accumulating this. This passive learning method leads to a lack of understanding of the key principles or problems of learning.

As a prior art for solving the above-mentioned problem, Korean Patent Registration No. 10-0593837 (published: April 26, 2003) is named "active learning material providing method that adds the interlocking function to the Internet video" The invention is disclosed, with reference to FIG. 1.

FIG. 1 is a diagram illustrating an active learning material providing screen in which an interlocking function is added to an internet video according to the related art.

Referring to FIG. 1, in the active learning material providing method in which an interlocking function is added to an internet video according to the related art, first, for example, a lecture 11 about an original equation is in progress, and the video lecture screen 11 ), An important part is a square marker. If the learner mouses over the marker and clicks, more detailed information and examples corresponding to the clicked portion are shown in the reference screen 12. After that, if the description displayed on the reference screen 12, the description alone does not feel or do not understand, or if you want to learn more details in a lecture, when the user moves the mouse and clicks the corresponding part, The video lecture is suspended, and the supplementary lecture screen 13 is activated to view the instructor's voice and the written lecture.

That is, if there is a part of the video lecture screen 11 that is not understood or is not understood by clicking on the rectangular marker of the portion related to the equation of the circle and seeing the additional explanation shown on the reference screen 12, it is understood there. Leave the part with the mouse and click on it to pause the lecture on the current equation, and the instructor's voice and writing lecture on the item selected in the reference screen 12 will be displayed on the supplementary lecture screen 13. appear.

According to the method of providing active learning materials according to the prior art, when a learner listens to an Internet video lecture, the learner misses the explanation or explanations missed by the instructor. Instructing the instruction information, by presenting supplementary data linked with this, it is possible to improve the learning ability of the learner by having an active learning thinking ability.

However, in the case of the active learning material providing method according to the prior art, the video lecture provider can provide the learner with reference materials and supplementary materials, but the learner can take notes because the video lecture provider is pre-edited by the video lecture provider. It does not provide learner convenience such as function.

On the other hand, a video learning player is being developed to provide Internet education. In the conventional video learning player, the video lectures are divided into sub-units and provided in a list form, and the unit-specific access is possible, but there is no function of directly displaying the part that the learner deems necessary. In addition, there was no replay of the marked parts. In order to re-learn only the necessary parts, incorrect methods were used, such as playing a video of the lecture from the beginning, or playing from a randomly adjacent time position. After all, in order to relearn, there was an inconvenience of having to play a part that the learner did not need.

On the other hand, as a prior art for solving the above-described problems, Korean Patent Registration No. 10-0504928 (published: March 14, 2005) discloses the invention named "notebook learning player device capable of note writing" 2 and 3 will be described in detail.

The learner management server 24 which provides services in response to the service request from the learner terminal and performs overall management, generates a learner information DB 25 and a directory for each learner, which store a video learning file to be provided to the learner. It includes a learner management DB (26) for storing a bookmark file, a section setting file or a note taking file (27) created during the learning.

Referring to FIG. 3, the video learning player 22 is divided into a video play unit, a video display unit 31, a text display unit 32, and the like, and the upper left frame is a manager, such as login, course board, self management, It consists of how to use and option buttons. The right frame is a text display unit 32, consisting of a list bookmark 34, taking notes 35 and repeated listening. The lower left frame is a video play section, progress bar, section setting bar, play / pause / pause, repeat listening selection / pause / listening, bookmark, volume control, play, pause, repeat listening, status display indicating play time, 0.5 It consists of a double speed selection for selecting a speed up to ˜2 times, and a screen size for selecting screen sizes in small, normal and overall.

According to the Internet education broadcasting system using the video learning player that can take notes according to the prior art, while playing the video learning information, the learner can mark the bookmark by specifying the location required, the learner can search the previously stored bookmarks You can play from the designated location. In addition, it is possible to learn by playing only a desired repeating section by setting a repeating section for repeat listening and specifying a repeating section name that describes the set section and searching for a repeating section previously designated by the repeating section name.

In addition, according to the Internet education broadcasting system using a video learning player that can take notes according to the prior art, create a single note-taking file for each course to enter the necessary content directly or to take notes by referring to the bookmark and repeating list If you need to learn later, you can play the specific part of the video file and use it for learning.

By the way, in the case of the Internet education broadcasting system using the video learning player that can take notes according to the prior art described above, the user can simply input text when taking notes, but, for example, complicated mathematical equations and learner-specific marks, etc. There is a problem that is not easy to input.

Meanwhile, Korean Patent Registration No. 10-0905705 (published: May 16, 2007) states, "A computer-readable record of a method, system, and program for providing an electronic notebook service using a digital pen and digital paper. An invention titled "Medium" is disclosed, with reference to FIG.

The electronic note content may be combined to regenerate and edit the generated electronic note content.

However, the above-described system for providing an electronic note service according to the related art provides electronic note contents irrelevant to video playback.

On the other hand, in the case of the conventional video learning player, the learner can not directly question the instructor because it is an online lecture, and even if a question is asked through e-mail or the like, it is difficult to specifically explain the content of the question about the corresponding part. In other words, if an instructor receives a question via e-mail, it is difficult for the instructor to pinpoint exactly what part of the video lesson is in the video lesson, and it is difficult to respond immediately because the instructor needs to check the entire video again. There is a problem.
