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

1 is a diagram showing a learning service system according to an embodiment of the present invention, and FIGS. 2 to 4 are exemplary views of a screen displayed on the instructor user apparatus of FIG. 1.

1, the learning service system 90 according to an embodiment of the present invention includes an instructor user device (hereinafter, user device 1) 100, a learner user device (hereinafter, user device 2) 110, It includes a part or all of the communication network 120, the content providing device 130 and the learning service providing device 140.

Here, "including some or all" means that some of the components such as the content providing device 130 are omitted, so that the learning service system 90 is configured or some of the components such as the content providing device 130 are other elements. It refers to a network device in the communication network 120 or a device that can be integrated and configured in the learning service providing device 140, and is described as including all to help the understanding of the invention.

The user devices 100 and 110 are user devices (hereinafter referred to as user device 1 (100)) used by instructors for lectures and learner user devices (hereinafter referred to as user devices 2 (200)) used by participants in the learning space. It includes, it may further include a screen device provided in the learning space. The user devices 100 and 110 include a microphone (hereinafter, a microphone), a smart phone, a laptop computer, a tablet PC, and the like, and may include at least one device. Here, a smart phone, a laptop computer, a tablet PC, a screen device, etc., may include a microphone or operate in conjunction. In addition, the user device 1 100 according to an embodiment of the present invention may further include a voice recognition module for recognizing the acquired voice in addition to the voice acquisition unit for simply acquiring the voice. In general, devices such as smart phones have a high probability of including a voice recognition module, so it may be possible to use a microphone in conjunction with it.

In this way, the user device 1 100 may be configured in various forms. For example, a microphone is configured separately from a smartphone and a laptop computer to communicate with the communication network 120, or a microphone is connected to a smartphone to communicate with the communication network 120 through the connected smartphone. can do. In addition, since various forms are possible, the embodiment of the present invention is not particularly limited to any one method.

In a room where time and space are limited, the instructor can lecture through the microphone to learners gathered there. Of course, this space may not have multimedia equipment, but it will generally be equipped with multimedia equipment such as a screen device. When it is determined that help is needed for learners using the user device 1 (100), the instructor searches for various learning materials or lecture contents in addition to the prepared learning materials (or lecture materials) or textbooks, and provides them directly to the learners. It can be displayed on the screen device. Since the instructor has a microphone, by uttering a voice command for searching, it is possible to search for learning materials or contents based on speech recognition and provide them to the participants or to the screen. Here, the learning materials or contents include learning materials or textbooks necessary for lectures, and may include additional materials or contents.

For example, suppose that the user device 1 (100) and the user device 2 (110) display the same electronic teaching material during the lecture of a professor. Of course, the instructor and the learners may execute an application that provides a learning service to synchronize the user device 1 (100) and the user device 2 (110), access the learning service providing device 140, and perform synchronization through this. In addition, an electronic textbook (hereinafter referred to as an electronic textbook) in an electronic form related to the lecture may be downloaded and displayed on the screen.

The user device 1 100 may receive a query for the class content from the learner using the user device 2 110 during the class in this step. Of course, it may be possible to directly receive through P2P communication, but in the embodiment of the present invention, it is assumed that all operations are performed through the learning service providing device 140. When receiving a query as described above, the user device 1 100 may confirm that there is a query from a learner regarding a specific page or a specific paragraph or a specific phrase (or sentence) of the electronic textbook. FIG. 2 illustrates an example in which a specific learner designates a page of a corresponding material (or is automatically recognized by the learning service providing device 140) in his user device 2 110 and queries with a comment. For example, it pops up on the screen in the form of a speech bubble 200 to inform the instructor that there is a query related to the page the specific learner viewed. Since the UI display method such as the speech bubble 200 may be formed in various forms, the embodiment of the present invention will not be limited to any one form.

The instructor of the user device 1 100 may check the query content that the learner inquired as shown in FIG. 3 by clicking the corresponding speech bubble 200 during or after the lecture as shown in FIG. 2. Of course, if the learner sends the query contents together when querying, this is transmitted to the learning service providing device 140, and when the query is received, the learning service providing device 140 prior to transmitting the query content, the user device 1 100 As a result, we can inform you that there is a query. Accordingly, when the instructor of the user device 1 100 clicks the corresponding speech bubble 200, the query contents stored in the (group) may be displayed again on the speech bubble 200 as shown in FIG. 3. In addition, when the instructor responds to the query content of the speech bubble 200, the corresponding answer may be displayed on the electronic teaching materials to all learners of the user device 1 100 and the user device 2 110. For example, the instructor may click the answered balloon 200 again to cause the comment window to appear on the screen, so that the reply may be processed.

Such a process may be able to show in real time both the process of inquiring and the process of answering. However, there may be unnecessary inquiries, and the fact that there is an inquiry as much as possible in case of an unexpected situation during lectures should be seen only by the instructor first, but when the instructor determines that there is a need to answer during the lecture, other learners learn It may be desirable to have all learners share the content of their questions and answers by immediately responding to help. In this way, how the class using the user devices 100 and 110 is to be performed is up to the intention of the system designer, and will not be limited to any one method. However, it is clear that the learner should be able to notify and respond to the fact that there is a query when the learner makes a query using the user device 2 (110) with an inquiry text, voice, or video.

The user device 2 110 is a terminal device such as a smart phone possessed by learners of a lecture, and may further include a laptop computer, a tablet PC, and the like. Depending on the interface of the learners, the user device 2 110 may perform a process for inputting learner information by accessing (or logging in to the lecture service) the lecture room established by the professor. Of course, as mentioned above, the instructor or his assistant may collect and input learner information before the lecture. Accordingly, the user device 2 110 may receive the lecture contents provided by the user device 1 100 and multimedia data such as a lecture note after the lecture is completed. In addition, the contents of conversations (eg, questions, responses, and discussions) between instructors and learners during lectures can be provided in conjunction with learning materials. Of course, the content of this conversation may be provided based on the edit information edited by the instructor using the user device 1 (100).

It can be seen that the user device 2 110 selectively receives lecture content or multimedia data depending on how the learning service providing device 140 is designed to provide lecture content or multimedia data. In other words, as mentioned above, if the instructor is designed to provide the user device 2 110 immediately when a search request is made, the searched lecture content will be provided immediately. However, if it is designed to be provided to the instructor according to the search request and the lecture content selected by the instructor is provided, the lecture content will be designed in that manner. Since these methods are variously changed depending on how the program is designed, it is not particularly limited.

Of course, there may be a query from the learner of the user device 2 110 during the lecture. In this case, the design may be made in various forms. For example, a record of a query voice of a learner is made through a professor's microphone, and will be stored in the learning service providing device 140 in the form of a voice file. Of course, the microphone installed on the screen device It is possible to receive any voice through, but the learning service providing device 140 records or analyzes the query of the voice file and the response of the instructor and transmits it to the learning space in real time or in the future embodiments of the present invention It may also be provided to other instructors who use the lecture service according to. As such, queries related to the user device 2 110 may be processed in a voice-based manner in addition to being made in the form of a bulletin board in the opened lecture room.

More specifically, the user device 2 (110) has a conversation such as a query or response regarding the search content requested by the instructor using the user device 1 (100), such as auxiliary data, or learning data or auxiliary data by searching. Once done, it can be sent in real time and displayed on the screen. In fact, such an operation may be possible because it is designed to be programmed and operated in the learning service providing device 140 so as to operate. Of course, if the instructor has edit information edited during or after the lecture using the user device 1 100, the content of the conversation may be edited based on the edited information and provided to the user device 2 110 or the screen device. . Of course, it is irrelevant to provide editing information before the lecture.

These learners belong to the class of learners who actively participate in class. However, introspective learners may return to the text or home through the user device 2 110 owned by the user rather than this method, and may inquire about a specific part of the corresponding learning material in the form of a voice or video recorded by the user himself. . Therefore, when these learners touch a specific page (or tap) during learning, touch a specific paragraph, or touch a specific phrase, a query window is displayed on the screen to query or transmit a voice or video file. You can. Of course, the combination is also possible. That is, it is a form of attaching a file with an inquiry text. In FIGS. 2 to 4, it has been already described that a specific learner queries through a comment using a comment related to a specific page of learning material.

If the instructor responds to the inquiry during the lecture in the user device 1 (100), other learners participating in the class may receive and check the answer to the query in real time. If you send an answer to the question after self-learning, learners who retake the course may be able to check the answer.

The communication network 120 includes both wired and wireless communication networks. For example, a wired / wireless Internet network may be used or interlocked as the communication network 120. Here, the wired network includes an Internet network such as a cable network or a public telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), and Wibro network. It includes meaning. Of course, the communication network 120 according to an embodiment of the present invention is not limited thereto, and may be used as a cloud computing network under a cloud computing environment as a connection network of a next-generation mobile communication system to be implemented in the future. For example, when the communication network 120 is a wired communication network, it is possible to connect to a switching center of a telephone station in the communication network 120. However, in the case of a wireless communication network, data may be processed by accessing an SGSN or a Gateway GPRS Support Node (GGSN) operated by a communication company, or BTS. (Base Station Transmission), NodeB, e-NodeB can be connected to various repeaters to process data.

The communication network 120 includes an access point (AP). Access points include small base stations, such as femto or pico base stations, which are often installed in buildings. Here, the femto or pico base station is classified according to the maximum number of user equipment 1 (100) or the user equipment 2 (110) can be accessed according to the classification of the small base station. Of course, the access point includes a short-range communication module for performing short-range communication such as Zigbee and Wi-Fi with the user device 1 100 or the user device 2 110. The access point can use TCP / IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, short-range communication may be performed in various standards such as radio frequency (RF) and ultra-wideband communication (UWB), such as Bluetooth, Zigbee, infrared (IrDA), ultra high frequency (UHF), and very high frequency (VHF), in addition to Wi-Fi. You can. Accordingly, the access point can extract the location of the data packet, designate the best communication path for the extracted location, and forward the data packet to the next device, for example, the learning service providing device 140 along the designated communication path. An access point may share multiple lines in a typical network environment, and may include, for example, routers, repeaters, and repeaters.

The content providing device 130 includes a server operated by a third party company or other educational institution such as universities or broadcasting stations that generates and provides learning materials by itself. The content providing device 130 may check and provide the questions and discussions in a specific lecture according to the linkage with the learning service providing device 140. Here, the interlocking operation of the two devices may be performed by business alliances of operators operating each device. In other words, when the new content is updated, the content providing device 130 checks whether the content is previously provided to the learning service providing device 140 to provide only new content.

The learning service providing device 140 includes a DB 140a for storing vast (big) data. In addition, the learning service providing device 140 provides the learning content searched based on voice to the user device 1 100 at the request of the user device 1 100, and is selected by the instructor among the searched learning content or the searched learning content. Only the learned content can be provided to the user device 2 (110). At this time, the searched learning contents may be provided based on received or pre-stored learner information. Of course, any of the above searched learning contents can be provided directly to the user device 2 (110), so the embodiment of the present invention will not be limited to any one method. Since this has been described above, further description will be omitted.

In addition, the learning service providing device 140 may generate multimedia data such as lecture notes by matching voices (signals) acquired during the lecture of the instructor and the searched learning contents with electronic teaching materials in real time. For example, when an instructor stores electronic teaching materials or learning materials such as PPT or PDF in a specific lecture room, the learning service providing device 140 acquires, matches, and stores the voices received in real time based on the data. In addition, if there is a question or answer in the course of a lecture or there is a searched content, it can be matched and stored according to a system designer's preset method. Here, the "pre-set method" is a programmatic aspect, but may include, for example, a process of generating a screen by attaching a question-and-answer tag in the form of a balloon. That is, the preset method is a format generated by a program that automatically generates multimedia data. Therefore, such a format may be formed in various forms, so the embodiment of the present invention will not be limited to any one.

Furthermore, the learning service providing device 140 extracts keywords such as a lecture name or a subject name when storing multimedia data such as lecture notes generated by the above process, and tags the extracted keywords in the multimedia data to generate a database 140 You will be able to save on. It can be said that the multimedia data generated in this way are searched based on keywords.

On the other hand, the learning service providing device 140 may perform an artificial intelligence function to search for more accurate learning contents based on vast data. Of course, this function can be applied variously to extract more accurate keywords to generate multimedia data. As is well known, artificial intelligence can maximize the learning effect by iterative learning based on probability and statistical algorithms.

In addition, the learning service providing device 140 also provides a service for learners who cannot actively participate in class due to limited lecture time and relationships between different students. In other words, the query of learners actively participating in the class can display the content of the query using, for example, an electronic textbook using a voice signal recorded during the class. In this case, in the case of a query having a specific event (for example, a joke), the instructor may set the query content not to be displayed on the screen, so the query content will be displayed on the screen in connection with the electronic teaching material.

On the other hand, learners who are somewhat less active in class can open a query window in the form of a pop-up window by touching a specific page or a specific paragraph or a specific phrase of the electronic textbook during the class and perform a query through the query window. In this case, the content of the query is transmitted to the learning service providing device 140. Then, when the inquiry service is received, the learning service providing device 140 informs the user device 1 100 that there is a query from a specific learner about a specific part of the electronic teaching material, and if the instructor checks the query content of the query received If you want to, the contents of the linked query will be sent. At this time, the content of the query may be in the form of a phrase or in the form of a voice file or video. Of course, when the instructor is notified of the question, it may be possible to check whether there is a question in the form of a comment, a voice file, or a video.

When the instructor performs a response to a specific query, the learning service providing apparatus 140 causes the contents of the query and the answer to be displayed on the screen on all devices in the learning space on the basis of the corresponding answer. In other words, questions and answers are displayed together on one side of the electronic textbook. This may have the form shown in FIG. 4.

On the other hand, when the pre-stored electronic textbook is updated, the learning service providing device 140 compares the data of the old version of the electronic textbook and the enhanced new version of the electronic textbook and stores them by linking questions and answers to common or related parts. Will be able to. Unless it is completely revised, there will be some revisions to the ordinary electronic textbooks, so this should not be a problem. In addition, even when the format for generating multimedia data is changed, existing query content or answer content may be automatically saved in the changed format. In other words, the format is a change in the visual appearance, and the category containing the related contents will not be changed.

5 is a block diagram showing the structure of the learning service providing apparatus of FIG. 1.

As shown in Figure 5, the learning service providing apparatus 140 according to an embodiment of the present invention includes a part or all of the communication interface unit 500 and the learning data processing unit 510, where "some or all of "Including" is the same as the previous meaning.

The communication interface 500 communicates with the user device 1 100 and the user device 2 110 via the communication network 120 of FIG. 1. According to an embodiment of the present invention, the communication interface 500 transmits the inquiry content through a pop-up window displayed on the screen by a learner of the user device 2 110 touching a specific page of the electronic teaching material or a paragraph or phrase of the corresponding page. If it does, it receives the corresponding query and provides it to the learning data processing unit 510. Of course, the received query content receives the identification information of the user device 2 110 that transmitted the query content, such as device information or user ID information. Here, the query content may be provided in the form of a phrase, but may be provided in the form of a voice file or a video file. The voice or video file is provided by a learner recording or photographing.

Also, the communication interface unit 500 notifies the instructor of the user device 1 100 when a query content is received from a specific learner under the control of the learning material processing unit 510. For example, when notifying that the query has been received through the communication interface unit 500, the learning data processing unit 510 may transmit information about the learner who made the query together. Here, the learner information may include various forms such as a learner's name, nickname, or photo, icon. Accordingly, the user device 2 110 may display a pop-up window (eg, a speech bubble) of a preset method on the screen and display the received learner information together. Here, the learner information may be replaced with another, such as a phone number or an email address, so the embodiment of the present invention will not be limited to any one method.

The learning material processing unit 510 performs various operations related to the learning service providing device 140 of FIG. 1. To this end, the communication interface 500 may be controlled. Above all, the learning data processing unit 510 notifies the user device 1 (100) when the query content is received from the user device 2 (110) of the learner in the learning space through the communication interface unit 500, and the user device 1 (100) ), If there is a request to confirm the query content for the query, the communication interface unit 500 is controlled to transmit the query content.

In addition, when the instructor who confirms the query content provides an answer to the query content, the learning data processing unit 510 receives the corresponding answer content and transmits it to the user device 2 110 of other learners. Accordingly, learners using the user device 2 110 can check the content of the query and the answer on one side of the electronic teaching material displayed on the screen. Of course, the same applies to the user device 1 (100).

Above all, the learning data processing unit 510 may perform different processing operations depending on the path through which the query is received. For example, active learners in class will boldly raise their hands and ask questions. In this case, the query contents of the instructor's microphone will be input, and thus, the learning material processing unit 510 may transmit the query so that all learners can see it immediately without notifying the instructor. Of course, if the query content is input from the user device 2 110 of the learners, the learning data processing unit 510 may determine that it is a public query and perform the above operation.

On the other hand, if the query content is received only from the user device 2 110 of a specific learner, the learning material processing unit 510 recognizes the position where the learner is wondering about which part the electronic device is tapping in the relevant part, You can use a speech bubble to signal that there is a query. In this case, only the instructor can know the facts rather than the public, so all learners may be able to confirm the content of the query only when the instructor answers.

As such, the operation of the learning material processing unit 510 may be variously performed. However, the learning material processing unit 510 according to an embodiment of the present invention will be irrelevant in any way as long as learners who are silent in class can actively increase their learning effects by actively inquiring their inquiries to the instructor. .

Other than that, the details related to the communication interface unit 500 and the learning data processing unit 510 of FIG. 5 are not significantly different from the contents of the learning service providing device 140 of FIG. 1, and thus the contents thereof will be replaced.

6 is a block diagram illustrating another structure of the apparatus for providing learning services of FIG. 1.

As illustrated in FIG. 6, the learning service providing device 140 ′ according to another embodiment of the present invention includes some or all of the communication interface unit 600, the control unit 610, and the learning data generation unit 620. Here, "including some or all" is the same as in the previous meaning.

Compared with the learning service providing device 140 of FIG. 5, the learning service providing device 140 'of FIG. 6 processes the control function and the learning data generating function of the learning data processing unit 510 of FIG. To that difference. In other words, the control unit 610 is in charge of the control function, and the learning data generation unit 620 performs a learning data generation operation.

More specifically, the control unit 610 controls the communication interface unit 600 and the learning material generation unit 620. For example, when there is a query for a specific portion of the electronic teaching material from the user device 2 110 of a specific learner, the query content of the received query may be provided to the learning material generation unit 620. Then, the control unit 610 may notify the user device 1 100 that there is a query, as requested by the learning material generation unit 620.

If, in the course of this process, the user device 1 100 requests confirmation of the query content, or the instructor provides an answer to the query content, the query content and the answer content can be shared with other learners. It is transmitted to the user device 2 (110) of all learners in the learning space. It can be seen that the operation related to this is performed by the control unit 610 and the learning data generation unit 620.

Since the learning material generation unit 620 has been sufficiently described above, further explanation is omitted. However, the learning material generation unit 620 basically performs an operation for generating multimedia material, which is a learning material, and the multimedia material is an electronic textbook related to learning, an additional learning content related to the electronic textbook, and a query related thereto. , It means a material that has various combinations of answers and discussions. Since the format depends on the intention of the system designer, further explanation is omitted.

However, as mentioned in FIG. 5 above, the learning material generation unit 620 provides a service that enables learners who are silent in class to actively participate in learning through their user device 2 110.

Except for the above, contents related to the communication interface unit 600, the control unit 610, and the learning material generation unit 620 of FIG. 6 include the communication interface unit 500 and the learning data processing unit 510 of FIG. In addition, since the configuration and operation of the learning service providing device 140 of FIG. 1 are not significantly different, the contents will be replaced.

Meanwhile, the control unit 610 of FIG. 6 may include a CPU and a memory according to another embodiment of the present invention. The CPU includes a control circuit, a calculation circuit, an analysis unit, and a registry. The control circuit can perform a control operation, the operation circuit can perform digital calculation processing of information, and the analysis unit can interpret the received machine language to interpret which user command is received and notify the control circuit to perform the related operation. have. The registry is a repository of data or information. Also, the memory includes RAM. Accordingly, when the initial driving of the learning service providing device 140 ', the CPU will be able to rapidly increase the operation speed by copying and storing the program stored in the learning data generation unit 620 in memory and executing it.

7 is a flowchart illustrating a process of driving a learning service providing apparatus according to an embodiment of the present invention.

Referring to FIG. 7 together with FIG. 1 for convenience of explanation, the learning service providing apparatus 140 according to an embodiment of the present invention is in an electronic form displayed on the learner's first user device (eg, the user device 2 with a query). In the electronic textbook, a query provided by a learner is received in relation to an arbitrary (or specific) page or a part of the page (eg, paragraph, phrase, etc.) (S700). More precisely, query contents are received, and user information is received together.

When a query is received, the learning service providing device 140 notifies that there is a query received by the instructor's second user device (eg, user device 1) in the same learning space as the learner (eg, on / offline space). If the instructor answers the query, the content of the query and the answer (previous) on the page or part of the page displayed on the third user device of the other learner in the learning space (e.g., the non-queried user device 2) Will be displayed (S710). If the instructor does not answer the question immediately, other learners may not know this.

In such a process, the learning service providing device 140 may process the query in different forms according to a path or method in which the query is input, and provide it to user devices. For example, the behavior is different by distinguishing the type of a learner who actively participates in a class and queries, and a type of a learner who actively participates and queries. In this regard, since the foregoing has been sufficiently described, further explanation will be omitted.

On the other hand, that all components constituting the embodiments of the present invention are described as being combined or operated as one, the present invention is not necessarily limited to these embodiments. That is, if it is within the scope of the present invention, all of the components may be selectively combined and operated. In addition, although all of the components may be implemented by one independent hardware, a part or all of the components are selectively combined to perform a part or all of functions combined in one or a plurality of hardware. It may be implemented as a computer program having a. The codes and code segments constituting the computer program may be easily deduced by those skilled in the art of the present invention. Such a computer program is stored in a computer-readable non-transitory computer readable media, and read and executed by a computer, thereby implementing an embodiment of the present invention.

Here, the non-transitory readable recording medium means a medium that stores data semi-permanently and that can be read by a device, rather than a medium that stores data for a short time, such as registers, caches, and memory. . Specifically, the above-described programs may be stored and provided on a non-transitory readable recording medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and it is usually in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. It is of course possible to perform various modifications by a person having knowledge of, and these modifications should not be individually understood from the technical idea or prospect of the present invention.
