Abstract

PURPOSE: A system for performing real-time bidirectional remote teaching on the internet is provided to perform the real-time bidirectional remote teaching regardless of places connected through the internet, by making teachers and students transceive writings and drawings as watching shared texts, listening to voices, and seeing faces to each side through the internet. CONSTITUTION: A system for performing real-time bidirectional remote teaching comprises a small-sized classroom, a large-sized lecture, a test education, and a managing program including a database. Functions of a visual screen and a conversation window are added in the small-sized classroom. A bidirectional lesson is performed in real time in the small-sized classroom as seeing faces of teachers and students to each side. The large-sized lecture uses a webcasting technique, and performs the real-time bidirectional teaching. The teachers are presented to many students. The students are selectively presented to the teachers. The text education uses bulletin board programs based on texts. The database of the managing program stores the students, the teachers, subjects, and schedules.

Description

Implementation and business method of real-time interactive video education system using internet {Mutually communicable video-audio real-time educational system and it's business model via internet}

The present invention is to build a real-time remote video education system via the Internet, and to propose a business model using the same.

The education of the future, as we see in the movie, has a large wall-mounted TV, through which a teacher and student can communicate with each other, not only in 1: 1, but also between students. In addition, multimedia textbooks will be shared on the screen. The present invention can be said to be the pioneering form of development into this form of education in the future.

Compared to the aforementioned form of future education, the existing distance education methods were insufficient in terms of 'real time', 'remote', 'interactive' and 'multimedia'. For example, in current Internet education, there are many cases in which materials are provided, downloaded, and used. However, this is just an off-line book, audio or video upload on the Internet. This form is reasonable in terms of remote and multimedia, but it is impossible to contact teachers in real time. In addition, there is the same form of problem solving, which solves a given data problem and shows the solution and the solution. This form corresponds to the form of real time, remote, interactive, and multimedia. However, there is still a lack in terms of bidirectionality. For example, you can't do things you need to do yourself, like pronunciation correction in foreign language education. Nor can you answer questions other than a given question in real time.

In addition, media such as television can provide a large amount of education at low cost. But the crucial disadvantage here is that it is unilateral. Interactive real-time video education is possible on the Internet. In the past, however, it could not be run in bulk. Of course, this is not impossible at all, but it requires a huge amount of money to achieve this, and there was no economic feasibility for education for business purposes.

The present invention is to build a system that allows the instructor and the student to face each other, listen to the voice, and look at the shared textbooks, the writing or pictures written by the instructor or student can be directly transmitted to each other through the Internet. B) It is also intended to suggest how to use it for business purposes.

Two systems were invented for the purpose of a). i) First is a remote video education system for small classroom environment. ii) Second is the remote video education system for large-scale lectures.

For i) tools for various educational purposes are added to an existing video conferencing system or video chat system.

For ii), streaming technology used for existing internet broadcasting or webcasting is used, and a tool for educational purposes is attached thereto. There are two types here, depending on how you connect users. One is the way the instructor lectures the students directly through the server, and the other is the way the instructor's computer performs the server function and delivers the lecture directly to the students without passing through the server. In the case of directly passing through the server, the number of courses that can be opened in one server is limited in order to obtain high quality image quality and sound, whereas the instructor's computer performs the server function only in the initial certification stage. By connecting the instructor and the students directly via the server, there is no burden on the server, and it is possible to lecture in the low-quality, low-quality image and voice of hundreds of units. The system is also very inexpensive compared to the existing real-time interactive Internet education system.

The underlying technology for such a system has already been developed, and the present invention is like inventing an eraser pencil by attaching an eraser to the pencil. Educational tools are added to existing video conferencing and video chat systems, and educational tools are attached to streaming technology for webcasting. Thus, in a small-scale video education system, students and teachers can look at each other's faces and listen to their voices. Ask questions right away and get an interactive experience.

The present invention is not naturally natural due to the limitation of the transmission speed of the Internet network and the hardware of the computer, and there is a slight limitation in the transmission of voice. However, as Internet TVs become more popular and home appliances and computers become more integrated, and the existing Internet network is improved, it will become more similar to the education of the future, which has been discussed in the near future.

This invention also adds a text-centric tool to one of the entire systems in order to achieve economic benefits as a business. Not all education needs to be multi-media. Therefore, text-based education is also necessary from a business point of view.

Projects based on the invention described above can serve educators and trainees in four forms. .

First, there is a form in which a company that installs the education system directly hires an educator and recruits trainees to provide lectures.

Secondly, the operator rents all or part of the above education system. This is unique to this business model. With the educational system of the present invention it is possible to provide almost unlimited space for small and medium lectures. This is similar to the situation where there are countless classrooms in a huge school and these classrooms are not fully used. At this time, the lecture room can be rented. The system provided by the present invention is free of such leases. Lending resources for small and large classes can serve educators and trainees. This type of lease can be further divided into two ways, one that literally leases the space. The other is to lend a space, and to introduce the educator to the educator and the educator to the educator, thereby paying for the lease of the space and the service of introducing the educator and the educator to each other. Such services may be used, for example, for college students who want to tutor, or for services that guide students' learning in tutoring or at school.

Third, to increase advertising revenue by showing ads on the homepage and lecture window. This announcement has the meaning of a kind of target advertising, which is advantageous for the advertiser, and will be a condition that can afford a low education cost to students.

Fourth, by providing textbooks and materials to the site where the educational system is installed, it provides a service that saves the trouble of visiting many places to purchase textbooks and materials.

The first, third, and fourth case above may not be so new. However, the purpose of this business model is to introduce the above education system and construct an educational site with a portal character. For this purpose, the above four types of services are integrated into one.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates the configuration of a site according to the present invention from the viewpoint of a user (accessor, educator and trainee). The user accesses this site through the Internet (HTTP, Hipertext Transfer Protocol), and sees the initial screen (1). Then, go to the shopping mall (2) to obtain textbooks or materials, or to the member registration section (3) to register for classes. Members consist of multiple levels. Members at each level have their own limits. The grade is upgraded according to the degree of use of the service. Senior members earn miles, bonus points, and discounts. In the shopping mall (2) or member registration (registration) (3) proceeds to a page for payment by credit card or cyber money.

Pre-registered members or course applicants are directed to the appropriate course through the membership certification process (4) (6, 7, 8). There are two methods of membership authentication, one using ID and password, and the other using cookie.

Figure 2 illustrates in more detail the process led to the appropriate lectures (6, 7, 8) in the member authentication (4) of FIG. Reference numerals 201 to 203 indicate a connector. The visitor must have a sound card, a PC video camera, a multimedia computer with a microphone and speakers (or a headset with a microphone). But video cameras are not necessary. If the visitor does not have a video camera, another picture may appear on the visitor screen instead. Sound cards are not necessary for text-based education.

The accessor may be a student, an individual such as an instructor, or may be a person or a group that rents the system of the present invention. Such a connection may be a direct connection to a web site on which the system is built, or an indirect connection from another web site. In the case of indirect connection, for example, by pressing an icon or a banner on an external website, it is possible to directly access the authentication system of the website on which the educational system is constructed.

The server 205 refers to the database 204 containing the student and teacher information, and authenticates whether the accessor is a legitimate user. If the user is a legitimate user, the server 205 refers to the database 204 containing the class subjects and the timetable and leads them to the appropriate classroom.

The database containing the class and timetable of the database 204 of FIG. 2 may be made into one or two. Suitable classrooms may be small classroom environment video education systems 206-208, or medium and large video education broadcast systems 209-211.

And although not shown here, there is management configuration software. It performs functions such as managing members, opening and destroying lectures, in conjunction with databases of students, teachers, courses, and timetables.

The process of leading from the certification to the appropriate classroom is summarized again in FIG. When the user connects (601), the user is asked for an ID and password (602). If the ID or password is incorrect, please enter it again. If a certain number of times is wrong, a specific screen is displayed (608). This can also be done using cookies. If the user has been connected before, the cookie is used to authenticate the user. If you do not have a cookie, enter your ID and password. If wrong, input again or show specific screen (608). This user authentication is made with reference to the student and instructor database 606.

If the user is registered (603), it is determined whether there is a current class (604). This is done by referring to a database 607 containing courses and timetables. If there is a scheduled class, it leads to the appropriate class (605), but if not, it displays a specific screen, such as showing the class timetable or reviewing the last lecture (610).

FIG. 3 is a view illustrating a connection method of a small classroom environment video education system in more detail with reference to FIG. 1 (6) and FIG. 2 (206 to 208). At 'accessor 1' of '301', 'accessor N' accesses the server 302 and undergoes a user authentication process. They then do not stay on the server 302 to be served by the server 302. Each visitor 301 informs the server 302 of its Internet address, and the server 302 receives them and notifies other visitors. The software on each visitor's computer is notified of the IP address of the other visitor and communicates directly with the other visitor without going through the server 302. As a result of this process, the accessors of 302 maintain their connections with each other, as shown at 303, and the server 304 is not involved. However, there may be times when one or some of the users are disconnected. In this case, when they come back, the server connects this new visitor to this visitor group (303). This process is possible by notifying new users of the Internet addresses of those users stored in the server, and notifying the existing users of the new users.

The function and interface of such a small classroom environment video education system is illustrated in FIG. 7. There are banner advertisements (701, 707), the title of the lecture and the name of the instructor or company name appear (702), and the current time and the time the lecture ends (703). It has the ability to automatically end a lecture when it's time to finish it. Students and instructors appear on the screen (705). Students and instructors can conduct lectures by looking at each other's faces and listening to their voices. If the accessor does not have a video camera, another picture, such as the character character, will appear on the screen corresponding to the accessor.

When a small number of students take a lecture, eight or ten images will be sufficient to represent these images (this number may increase or decrease). However, more than one student may need to participate in the lecture. Students who are not accepted on this screen appear at 704. 704 shows the student's name or ID. The students appearing at (704), of course, take the same lectures as those on the screen. However, these students may optionally appear on the screen. In other words, by clicking on the student's name or ID, the image of the student replaces the person who was previously seen. Your image does not have to appear on the screen. Thus, the instructor can display students' own images on the screen instead of his face, and he or she can have the name appear in the window of 704. The same is true for students.

It is inherent in the present invention to be able to switch between the person 705 and the person 704 whose name appears. By having such a system, a lot of people can be accommodated in the course. Therefore, this small video education system becomes a flexible system that can accommodate a small number of people and more people.

The function button 706 includes a 'speak / listen' button to define the right to speak, a function of indicating who is speaking, a whiteboard, a file transfer, the ability to end a lecture or extend the time, and an appearance of the screen. There is a function button to adjust. Whiteboard is a function that the contents of the instructor or students are delivered to the other party as it is. This includes palettes to choose colors, tools to draw shapes such as straight lines and circles, the ability to write, and an eraser to erase what is written. Whiteboards are made of floating windows to free screen layout. The file transfer function can be used by the instructor to give students homework or test questions. Conversely, they can also be used to submit assignments. The presentation screen of 708 is a window for sharing screens such as Hangul Hangul, Microsoft Word, and PowerPoint. This can be used when an instructor shares a textbook that has already been made to students. There are chat windows that can share text messages (709, 710). In addition, it includes a whisper function that enables 1: 1 conversation. This feature can be used to simply ask or answer a specific student.

The large-scale video education broadcasting system shown in FIGS. 1 (7) and 2 (209-211) is shown in FIGS. 4 and 5. This educational system is an application of a technology called Internet broadcasting or webcasting. In general, Internet broadcasting uses a technology called streaming, which does not download and play the entire material, but reproduces it as soon as it is received. This is similar to the broadcast as in the radio broadcast. Such a system can broadcast recorded content, but can also broadcast in real time. There are several systems that implement this streaming technology, such as Real System, Window Media, and StreamWorks. The present invention has been made possible by adding several educational tools to this system (FIG. 8).

The system shown in FIG. 4 is for large scale lectures. Here, the instructor 401 lectures the students 403 to 406 via the server 402. Not only here, but throughout the description of the present invention, however, it is assumed that all students have video cameras and sound cards, microphones and speakers. The lecturer's lectures are broadcast to the students via a server in real time (webcast), in which one server can handle only one lecture at a time. Therefore, it is impossible to open several lectures through one server. However, it is possible to obtain high quality and sound quality by broadcasting on the server. It can also accommodate more users. Therefore, lectures via these servers are suitable for large classes.

The system shown in FIG. 5 can be used in smaller, medium-sized lectures. The instructor 501 and the students 502 ˜ 505 are directly connected to each other after authentication at the server 506. This allows each visitor to tell the server their Internet address, and the server tells each visitor all of these addresses so that they can communicate with each other directly, without going through the server. This process is the same as in small video education systems. However, unlike this small video education system, the instructor's computer functions as a webcasting server. Therefore, the relationship between students is ignored, and the relationship between the teacher and the student is important. Student relationships are mainly possible only through the instructor. Student relationships are complemented by textual means, not by image or voice. Such systems can be used in medium-sized lectures because of the limitations of personal PCs and the speed of the Internet.

Functions and interfaces in the educational broadcast system of FIGS. 4 and 5 are illustrated in FIG. 8. There are banner advertisements (801, 808), and lecturers can be seen teaching (806). Under the screen reflecting the instructor's appearance, the instructor's writing flows like subtitles (806). Below it is a button to download the materials presented by the instructor (807). On the right side, there is a dialog input window 804 for asking or answering a question and a window 803 for showing the contents of the conversation. This is a major means of maintaining student communication. On the right are the function buttons (802). The function button has a function of requesting the right to speak or listening to other people, and there is a part showing who is speaking. You can communicate your thoughts by writing or drawing a whiteboard. Transfer files, end lessons, or extend lessons. And you can change the appearance of the software.

The merit of this educational system is that people can participate in the class while watching the video and sound directly. This means that in the case of small (figure 3) or medium (figure 5) lectures, after the certification phase, participants no longer rely on the server, and are directly connected to each other using Internet addresses, with little burden on the server. Is possible.

If we call the classroom the environment in which a class is held (specifically, the participants of the Internet-connected class as shown in Figures 3 or 5, and the educational system environment they see in Figures 7 or 8). If the class is called a classroom), this classroom system can be expanded almost without limitation. This is a very economical way because you can afford it on a single normal server.

The large-scale lecture system as shown in Figure 4 can only open one course at the same time in one server, it can not have the advantage that the above-described accessor is directly connected through the Internet address. However, this method has the advantage of being able to open a class in which a large number of trainees participate.

Other than this, there is a bulletin board-type program that focuses on text education. This is something that must be in place for the entire Internet education business.

Based on the above Internet education system, the education business on the Internet can be promoted in the following manner.

The first is that the company that installs the education system directly recruits educators and trainees to open courses and provide educational services. Operators recruit instructors, open courses, recruit students and provide educational services.

The second is to rent all or part of the educational system. Small and medium lecture systems in this system can provide room for countless courses without burdening the server. Therefore, the space for the lecture (classroom, classroom) is rented. This is analogous to having a huge building, providing some or all of it as a space for a school or a school. You could, of course, sell the whole thing.

This business method will be described in detail as follows.

There is no question about renting the entire system. You can even sell it. However, there are many ways to rent part of the system. For example, a) you can simply provide space for lectures (classrooms, classrooms). These services can be used, for example, in schools, institutes, or in company employee training programs. They recruit their own instructors and students to use only the space of this educational system. b) The establishment of this education system provides space, recruits educators, and introduces one of the educators to the educators. Therefore, the person using this service is provided with space, and the trainee or the educator is introduced. These services are available to students who wish to tutor. It may also be used for recruiting students at the school. For example, students who want to learn flower arrangements may voluntarily gather to open classes and have instructors. In the case of using such a rental service, it is possible to provide a necessary service at a lower cost than building a system.

In addition, there are many ways to access these services. You can go directly to the site where the educational system is installed and link to the course. You can also use hyperlinks such as icons, text, and pictures that link to your course on your homepage. In this case, since the user is directly connected to the homepage of the rental company, the rental company can be freed from the burden of leaving their home.

Even in the case of a large lecture system (Fig. 4), it is not impossible to rent or rent. In this case, for example, the landlord may lease on an hourly basis.

The third is to show ads on the homepage or lecture window. Due to the nature of the educational site, advertisers can target ads, and it also means that users can obtain the information necessary for education. The advertising fee will contribute to keeping the tuition fee low.

Fourth is a shopping mall that sells textbooks and materials. Make it easy for students to find the textbooks and materials they need without having to go around.

This business model is based on the small, medium and large lecture systems implemented in this educational system. These systems and business methods will be more powerful as the Internet develops and home appliances such as Internet TV, video telephones that can be connected to the Internet, and computers and the Internet will be integrated.

According to the present invention wherever the Internet is connected, real-time interactive video education is possible without any limitation of space. Classes similar to off-line classes, in which students and teachers face each other, are available on the Internet, and large-scale, real-time interactive education can be inexpensively constructed.

In addition, this invention has made it possible to rent and use as much space and time as needed even without constructing its own site.
