Description

Summary note system for educational content {Summary note system for educational content}

The present invention relates to a summary note system for educational content, and more particularly, to a summary note system for educational content that enables a user to effectively organize summaries when playing specific educational video content.

In general, it is a trend to search for recent searches on YouTube along with portal sites.

However, since it is a video that plays according to time, in order to find a specific scene,

There is a problem with the search function, as you need to find a specific scene by rewinding and skipping the playback time of repetitive videos. Moreover, when the size of the video content is large, it is more difficult to find a specific scene. In addition, in information delivery media such as text books and e-books, it is possible to underline important sentences, mark with a highlighter, or write important keywords.

However, in order to perform such an action in a video that is played over time, it is inconvenient to have to underline the text and keywords through a notebook or computer for the contents at a specific point in time while the video is paused at a specific point in time.

And as an example of the prior patent technology, in the registered patent publication No. 10-0658463

In the note, an image captured from a video such as a movie, music video, or film is edited according to the characteristics of the note to be produced, and the representative image of the video is edited together with the title and inserted on the front cover of the note, In , the contents and peculiarities of the video composed on one side of the first page are recorded on the left side of the paper, the first image of the video is inserted on the right side, and captured and edited in the order of implementation of the video on the inside after that The image is sequentially inserted on each page from the front at the same location, the front cover and the back cover printed with a unified image are inserted, and one side of the finished video note is bound by mutual adhesive means. A video note is released, characterized in that the image is realized as a video by grabbing it and turning it sequentially and continuously at a constant speed.

In addition, Patent Registration No. 10-2035225 discloses a method for providing a multi-content note by an apparatus for generating a multi-content note, the method comprising: generating a plurality of images selected by a user's image selection input as image data;

generating voice data by receiving a user's voice;

receiving a touch input input by a user on the plurality of images, and generating touch input data, the touch input data including a plurality of coordinate values and writing instrument type information, based on the received touch input step;

generating a file in which the image data, voice data, and touch input data are combined; and outputting the file;

Including, in the step of receiving the touch input, further receiving input time information corresponding to each of an arbitrary number of coordinate values per second with respect to the user's touch input at different speeds, and the respective coordinate values are input The input time information is synchronized with the voice data by matching with the elapsed time of the voice, and the plurality of coordinate values are a coordinate system set virtually in the image - the coordinate system outputs the image A method of providing a multi-content note is disclosed, characterized in that the coordinate values are according to - which is set virtually according to the display unit standard of the terminal.

However, the prior art still has the inconvenience of having to underline text and keywords through a note or computer for the contents at a specific point in time while the video being played over time is paused at a specific point in time, and the educational content is reproduced However, there was a disadvantage that it was inefficient and complicated to make a summary note for the video.

Accordingly, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a system capable of easily and efficiently making a summary note for a corresponding video while playing educational content.

The present invention relates to a summary note system for educational content, comprising: a keyword input and frame capture step for a user to generate a keyboard event when playing a video educational content;

It is characterized in that it includes an arrangement and annotation writing step in which the user efficiently writes summary notes by outputting keywords and captured video frames to the system screen.

Therefore, the present invention has a remarkable effect that enables the user to effectively summarize the content when reproducing a specific educational video content.

The present invention relates to a summary note system for educational content, comprising: a keyword input and frame capture step for a user to generate a keyboard event when playing a video educational content;

It is characterized in that it includes an arrangement and annotation writing step in which the user efficiently writes summary notes by outputting keywords and captured video frames to the system screen.

In addition, the keyword input and frame capture step is characterized in that a keyword is generated by inputting a keyword with a keyboard at a specific point in time, or a video frame of the corresponding point is captured through a space key input.

In addition, the summary note is characterized in that it includes keyword-based text information, image information at a specific point in time in the video, and video bookmark information based on playback time.

The present invention will be described in detail with reference to the accompanying drawings as follows.

In general, video content has the following characteristics.

(1) Image information at a specific point in the video + subtitles (video frame)

(2) Bookmark information is included.

Thumbnail information for image information and bookmark information have the advantage of being able to directly play a video at a specific point in time.

The system of the present invention enables a user to effectively organize summary when playing specific educational video content.

The system is divided into two stages. In the first keyword input and frame capture step, the user may generate a keyboard event when playing video educational content. You can create a keyword by entering a keyword with the keyboard at a specific point in time, or capture a video frame at that point in time by entering the space key. In the second arrangement and annotation writing stage, the keywords obtained earlier and the captured video frame are outputted to the system screen so that the user can write summary notes efficiently. These summary notes include keyword-based text information, image information at a specific point in time in the video, and video bookmark information based on playback time.

The system of the present invention generates keywords by the user inputting keywords with the keyboard at a specific point in time in the video input as shown in FIG. 2, and captures video frames at a specific point in time through the space key input to display the keywords and the captured frames on the system screen. It consists of a keyword input and frame capture step that outputs

The left side of FIG. 2 is a keyword input and frame capture step, which is the first step. In this step, when the video input by the user is played, the user can generate two events.

The first event generates keywords by typing characters with the keyboard and pressing the enter key. The keyword generated in this way will be called "hypertext" that has bookmark information at the time of creation. Therefore, when a keyword is clicked, the video playback time is changed according to the bookmark information of the keyword.

The second event is the action of pressing the space key on the keyboard, which captures the video frame at the time the video is played. Here, the captured frame is image information.

The image information has bookmark information at the time of capture. Therefore, such image information is called "hyper image". Therefore, when an image is clicked, the viewpoint of the video is changed according to the bookmark information of the image. The user repeats the above two events until the video playback ends.

As shown on the left of FIG. 2 , the user types with the keyboard when the video playback time is “0:18”, and the keyword “on the exam!” is generated. Also, when the video playback time was "0:24", the video frame was captured by pressing the space key on the keyboard. Through repetition of these events, keyboard and image information can be obtained.

The right side of the figure of FIG. 3 is the second arrangement and annotation writing step (Arrangement and Annotation Step). In this step, a summary note is prepared using the keywords and image information generated in the previous step.

Users can sort keywords ("on the exam!" + 00:18, "for example" + 00:35) and images (captured image + 00:24, captured image + 00:51) in any order. Users can also annotate hyper keywords and hyper images. The user can use the hyper keyword and bookmark information of the hyper image to write the necessary information as an annotation while viewing the target image again. Also, if there is text in the image, the same text can be extracted and imported. Accordingly, the user can quickly obtain the text of the image by using the text extraction function. The displayed hyper keywords and hyper images can be deleted, and the summarized summary can be saved.

On the right side of the figure in Fig. 3, the hyper keywords and hyper images obtained in the "keyword input and frame capture step" are shown. They are not arranged sequentially, but may be arranged in an order desired by the user. The user writes a comment saying "Scenes monitoring concretely!" The user also extracts the text "on the exam!" from the hyperimage and includes it as a comment. Using these functions, users can arrange and organize hyper keywords and hyper images to create summary notes.

As shown in FIG. 4 , a user inputs a target video in an “Input Target Video Area” and displays a screen for playing the target video. Then the system will start working.

The above screen shows the "keyword input and frame capture step" screen according to the selected video input. When the target video plays, the user enters the keyword "On the Exam!" via the keyboard and presses Enter. Then "on the Exam!" is displayed as a hyper keyword in the "Create a Summary Area" on the left side of the system screen above.

Similarly, if the space key is pressed during video playback, the frame of the target video at that point is captured and output as a hyper image to the left "Create a Summary Area" of FIG. 5 .

Since bookmark information is included in hyper keywords and hyper images, a specific point in time of the target video can be played immediately. The user repeatedly inputs a keyword or presses the space key until the target video is played. The screen of FIG. 6 shows a screen of the Arrangement and Annotation Step, and is a screen for writing a summary note using the hyper keyword and hyper image output in the keyword input and frame capture step, which is the previous step.

When the hyper keyword is displayed on the screen, the user can annotate the hyper keyword and additional information related to the hyper image in the input window through the input window. Additionally, when a hyperimage is displayed on the screen, a "Text Extraction" button is displayed at the same time.

As shown in the screen of FIG. 6 , when the user clicks on the hyper keyword “on the Exam!”, a specific point in time of the target video is immediately played through the bookmark information of the hyper keyword. This can be seen in the video in the right pane of the screen. Accordingly, the user can add necessary information to the input window as a comment while reviewing the target image at a specific point in time through the bookmark information. Here, "on the Exam!" Added "Scenes mentioning that they are good at exam" to keywords.

As shown in FIG. 7 , when a hyper image is similarly output, the user may additionally add information related to the hyper image to the input window as a comment. A "Extract Text" button is also created along with the input window. In the above screen, when the user clicks the "Text Extraction" button, the text of the hyper image is extracted and displayed in the input window.

Therefore, you can quickly get the text in the image information into the input window through the "Text Extraction" button. There may be cases where you want to additionally input user comments rather than extracting text. Since the image also has bookmark information, the user can add necessary information to the input window as a comment while reviewing the target image at a specific point in time through the bookmark information.

In addition to that, each displayed hyper keyword and hyper image can be deleted. Also, they may be arranged in an order desired by the user. Ultimately, the summary notes organized through this process can be saved by giving them a title.

By making a video content summary note in this way, the video is paused at a specific point in time, and the content at a specific point in time is captured or keywords can be entered. After that, if you write a summary note using the functions described above, you can write more conveniently.

As shown in FIG. 8 , the stored summary notes can be checked through the summary note list screen as shown in the screen above.

In the summary note list screen, for each summary note post, there are the title of the summary note, "Thumnail View", and "Detail View" buttons.

When “Thumnail View” is clicked, as shown in the screen of FIG. 9 , a thumbnail view function of collecting only image information of the summary note and outputting it on the screen is performed. "Thumnail View" displays all image information of the summary note along with the title of the summary note on the screen.

If the length of the video content is long and there are many captured images and input keywords, it is difficult for the user to grasp the overall contents of the summary note at a glance. Therefore, it provides summary information of the entire video at a glance visually through "Thumnail View".

10. Also, the "Detail View" button is a button that moves to the screen above where the details of the selected summary note post can be viewed. Summary Note Through the detailed screen, information about the video created by the user can be grasped.

In the above detailed screen, a summary and an "Update" button are displayed. The user can delete a specific hyper image or hyper keyword by pressing the delete button on the keyboard, and the annotation of the hyper keyword and hyper image can be edited by pressing the mouse cursor, and the final change is reflected by pressing the "Update" button.

The generated summary notes can be re-reviewed at any time, and users can jump directly to a specific point in the video via stored hyper keywords and hyper-images without having to repeatedly play specific video content for learning.

In addition, the stored hyper keyword enables the content search of the video as text-based, so that the content of the summary note can be indirectly searched.

If there is a specific scene of a specific video that the user wants to watch again, and the user has 100 60-minute videos, roughly calculating the time the user can find the desired video among 100 videos is 60*100* 1/2 = It can take 50 hours. However, the summary notes compiled using the system contain keyword-based text information.

Therefore, if a specific scene desired by the user is registered as a keyword, it is possible to indirectly support searching for contents of a video previously learned through the keyword.

When the keyword "modeling" is searched for in the search window as shown in the screen of FIG. 11, a summary note in which the keyword is registered is searched. This is because the keyword "modeling" is registered in a specific summary note previously registered.

Therefore, when you search for content through the system, you can quickly find not only a specific video but also a specific scene of the video.
