Description

Smart group learning system that enables efficient information sharing {SMART GROUP LEARNING SYSTEM FOR EFFICIENT INFORMATION SHARING}

The present invention relates to a smart group learning system capable of efficient information sharing using an electronic whiteboard.

Recently, the development and use of learning technology using portable terminals such as smartphones and smart notes has been actively conducted.

In other words, research is being actively conducted to utilize portable terminals as a learning tool in schools and academies.

Following this trend, as communication management systems in education-related fields are developed, the network environment of schools at each level is transitioning from a wired environment to an integrated wired and wireless environment, and wired and wireless terminals for classes are being distributed to individual teachers and students.

By connecting teacher terminals and student terminals through portable terminals and wireless communication functions, learning efficiency can be improved through various functions.

The current general teaching method is to mirror the teacher's teaching contents on a large screen so that they can be viewed as a whole through a beam projector or electronic whiteboard, and the teacher teaches while looking at the mirrored screen. Through the electronic whiteboard, the teacher only checks the learning materials. Also, the parts written by the teacher on the electronic whiteboard did not remain after class, and only the teacher's learning materials remained. In order for the teacher to understand the learner's educational situation, he or she had to go to the learner's seat or have the learner contact the teacher directly. It was cumbersome as we had to provide data.

For example, in response to a question given to a user by a teacher, learning progresses through two-way communication between the teacher and the user, but the process of the user solving the problem and the process leading up to the result is shared with all users and the teacher provides the correct answer. There were difficulties in the interactive learning process in which teachers and users shared through electronic whiteboards and personal PCs to provide advice on the process for deriving results.

The main terminal 100 is configured to provide learning or presentation material information, and is controlled by an instructor providing the material, a collaboration subject, and a co-participating facilitator, that is, a user serving as a master.

The sub terminal 200 receives information provided by the main terminal 100 and mirrors it to the display unit or has an input function, and is controlled by learners, collaboration partners, and co-participants.

In the future, for a smooth explanation of the main terminal 100 and the sub terminal 200, the user using the main terminal 100 will be referred to as an 'operator', and the user using the sub terminal 200 will be referred to as a 'user'. Let's do it.

Although there is only one main terminal 100, at least one sub terminal 200 may be provided for each user depending on the number of people in the group.

The main terminal 100 and the sub terminal 200 are not configured separately and can be distinguished according to the mode of the operating application, which will be described later.

The electronic whiteboard 300 may receive information provided by the main terminal 100 and mirror it to the display unit, or may be in the form of a touch screen with an input function. The electronic whiteboard 300 is configured to be shared and displayed to all users. As such, it is possible to form all configurations with the same purpose.

Additionally, the electronic whiteboard 300 includes a voice acquisition unit (not shown) capable of acquiring voice.

Since the electronic whiteboard 300 is in the form of a touch screen, when the operator wants to explain the data being output, he or she can write on it or erase it, and the user can also input it directly offline, and can be connected to the main terminal through the console box 400. It is configured to be connected to (100) and each sub terminal (200).

Additionally, it is obvious that information input through the operator's main terminal 100 can be applied to the electronic whiteboard 300 in real time.

When the screen selected in the main terminal 100 is displayed on the electronic whiteboard 300, it is possible to check the screen contents of the participating sub terminals along with exposure of the participating sub terminal list.

In addition, when each user solves a problem through the sub terminal 200, the screen of the sub terminal 200 of the user randomly selected by the operator through the main terminal 100 is displayed to check whether the users have solved the problem properly. is printed on the electronic whiteboard 300 to enable easy feedback.

The console box 400 is hardware connected to the main terminal 100, the sub-terminal 200, and the electronic whiteboard 300 and is connected to the main terminal 300 according to control information received from the main terminal 100. Controls sharing and splitting the screens of 100 and sub terminals 200. Control information received from the main terminal 100 is transmitted through the operating application.

As shown in FIG. 2, the console box 400 is composed of a connection unit 410, a transceiver unit 420, a control unit 430, a recording unit 440, and a storage unit 450.

The number of sub terminals 200 directly connected to the connection unit 410 of the console box 400 is limited, but can be expanded by connecting a plurality of console boxes 400 in parallel.

The connection unit 410 is configured to connect the main terminal 100, the sub terminal 200, and the electronic whiteboard 300. As shown in FIG. 3, the screen control port unit 411 and the USB input/output port unit. Divided into (412).

The screen control port unit 411 includes a screen input unit 411a for inputting a screen by connecting one or more of the main terminal 100 and the sub terminal 200 supporting HDMI, and the main terminal 100 supporting HDMI, One or more of the sub-terminal 200 and the electronic whiteboard 300 are connected to form a screen output unit 411b that outputs a screen.

In addition, the USB input/output port unit 412 connects and controls one or more of the configuration of the main terminal 100 supporting USB, the configuration of the sub terminal 200, and the touch input unit of the electronic whiteboard 300.

For example, an input device that supports HDMI, such as a computer, video device, laptop, camera, mobile phone, tablet, etc., can be connected to the screen input unit 411a, and an electronic whiteboard that is an output device that supports HDMI can be connected to the screen output unit 411b. , beam projectors, monitors, signage (digital signage), TVs, LED signs, etc. can be connected.

In addition, the USB input/output port unit 412 may be a touch panel, wireless keyboard, or wireless mouse connected to one or more of the USB devices such as the main terminal 100, sub terminal 200, and electronic whiteboard 300, and may be a separate USB device. External hard drives and USB memory can be connected.

The connection unit 410 includes a wireless connection unit for wireless connection of terminals such as smartphones and tablets, and a power connector for power connection.

The transmitting and receiving unit 420 transmits and receives information between each component connected to the connecting unit 410.

For example, learning or presentation material information received from the main terminal 100 is transmitted to the electronic whiteboard 300 or a plurality of sub terminals 200, or one sub terminal 200 selected by a command of the main terminal 100 The information may be transmitted to the electronic whiteboard 300 or another sub terminal 200.

Figure 4 is a block diagram showing the control unit of the console box of a smart group learning system capable of efficient information sharing according to an embodiment of the present invention.

The control unit 430 analyzes the web server 431, which receives information about the operating application in the form of a web page and converts it into parameter values, and data related to permission to use the electronic whiteboard 300 among the parameter values received from the web server 431. ㆍA screen sharing unit 434 that analyzes and determines data related to sharing permissions of the electronic whiteboard 300 among the selection unit 433 for judgment and the parameter values received from the web server; and among the parameter values received from the web server An authority delegation unit 435 that analyzes and determines data related to whether or not authority is delegated to the electronic whiteboard 300; and data related to the selection unit 433, the screen sharing unit 434, and the authority delegation unit 435, respectively. It is characterized by including a processing unit 432 that processes the data analyzed and judged.

The selection unit 433 can select whether to delegate authority to use the electronic whiteboard 300 to the sub terminal 200 when the operator sets whether to delegate the use of the electronic whiteboard through the operation application of the main terminal. Control it so that The mode is divided into authority maintenance mode and authority delegation mode.

In normal times, only the main terminal 100 is set to authority maintenance mode so that the authority to use the electronic whiteboard 300 is managed and controlled, so only the main terminal 100 can operate the electronic whiteboard 300, but in authority delegation mode, any one If you designate a sub terminal, authority is delegated to that sub terminal, and the display part of the console box is configured to display the delegated sub terminal.

When the screen sharing unit 434 sets the screen sharing information to be shared on the screen of the electronic whiteboard 300 through the operation application of the main terminal, the screen of the sub terminal 200 shared with the screen of the main terminal 100 is displayed. Controls sharing functions on the electronic whiteboard 300.

The screen sharing unit 434 is divided into an overall sharing mode that shares all of each sub-terminal and an individual sharing mode that shares a portion of each sub-terminal.

In addition, the screen of each sub terminal designated for screen sharing displays the same content displayed on the screen of the main terminal, and the screens of the sub terminals designated for screen sharing are displayed in a matrix form on the main terminal screen.

At this time, it is obvious that in the case of the sub terminal 200, the displayed screen can be changed according to the user's selection.

The screen of the main terminal can also display the entire screen of an optionally designated sub-terminal. Additionally, depending on the selection of the main terminal 100, the content written on the screen of some sub terminals designated for screen sharing can be designated to be displayed on the electronic whiteboard.

The designation of screen sharing between groups in a smart group learning system capable of efficient information sharing according to an embodiment of the present invention is as follows.

As shown in FIG. 5, when the operator in the main terminal 100 specifies the screen information of PC02 to be shared with PC01 through the operation application using a pull-down menu, as shown in FIG. 6, the web connected to the operation application When the shared screen number value received through the page and the shared screen number value are transmitted to the web server 431, the web server 431 converts them into corresponding parameter values and transmits them to the processing unit 432, the processing unit 432 ) shares the screen information of PC02 with the electronic whiteboard 300 and sub-terminal 200 PC01 connected to the connected console box 400. In the embodiment, when PC02 is selected on the PC01 sub-terminal, PC02 is displayed on the screen of the PC01 sub-terminal. The screen information is shared, and the screen information of PC02 is set to appear on the electronic whiteboard 300 at the same time.

In this way, the screen sharing unit 434 of the control unit 430 controls the screen information of the main terminal 100 and the sub terminal 200 to be shared and divided and output on the electronic whiteboard 300, and at the same time, the selected sub terminal Control sharing to output the screen of another sub terminal at (200).

That is, the control unit 430 receives the information of the sub terminal 200 shared by the main terminal 100 and the shared sub terminal information, and based on the information of the sub terminals 200 connected through the connection unit 410 according to the port. Control screen sharing with .

For example, if an error occurs in the problem-solving process of one user sub-terminal 200 among the plurality of user sub-terminals 200, the process in which the error occurred and the result are reported to all user sub-terminals 200 or the error. It is possible to selectively share it by selecting some of the generated user sub-terminals 200.

The main terminal 100 checks and judges the problem-solving process and results of the user sub-terminals 200, and if it is a general simple error, shares it only with some user sub-terminals 200 in which the error occurred. If it is a major error, it shares it with all user sub-terminals (200). 200), it has the effect of further increasing the learning effect by preventing the same mistake from being made in the future.

A simple error refers to a state in which the problem-solving process and results are normal and a numerical error simply occurs, while a major error refers to a state in which both the problem-solving process and results are incorrect.

In addition, if the problem-solving process in any one user sub-terminal 200 among the plurality of user sub-terminals 200 is written exemplarily, the exemplary problem-solving process and results are sent to all user sub-terminals 200 or errors. It is characterized by a configuration that selects and selectively shares among some generated user sub-terminals 200, which can increase positive learning ability by selecting and selectively sharing considering the learning ability of all learning subjects. It works.

For example, as shown in FIG. 7(a), when screen sharing of a plurality of sub terminals 200 is requested from the main terminal 100, the control unit 430 selects some of the plurality of sub terminals 200. Alternatively, if you select the corresponding sub-terminal 200 to be shared in its entirety, the screen information of the corresponding sub-terminal 200 is shared to the selected sub-terminal 200 in part or in its entirety, and if there is more than one shared screen, the electronic It is possible to control the blackboard 300 to be divided into multiple screens and shared in the form of a matrix or pop-up window.

In addition, as shown in 7(b), the control unit 430 controls the screen of the main terminal 100 when the screen of the main terminal 100 is output and displayed through the electronic whiteboard 300, when the user of the main terminal 100 uses the sub terminal 200. A chat window can be formed and operated on the screen of the main terminal 100 and the sub terminal 200 to receive user opinions and express opinions between both parties. The chat window can be operated on the screen of the main terminal 100 and the electronic whiteboard. It can be formed as a separate frame so that it can be exposed to (300) simultaneously.

The authority delegation unit 435 means delegation of authority to use the electronic whiteboard 300, which gives the authority to write or write content on the electronic whiteboard 300 through each sub terminal or to access the electronic whiteboard 300 directly. Controls the authority to go and write or write content.

In other words, the authority delegation unit 435 grants the main terminal permission to use the electronic whiteboard to the sub terminal through an operation application, but the sub terminal is given the ability to select whether to disclose screen information.

More specifically, in relation to delegation of usage rights, “Public” and “Private” display windows are formed on the screen of each sub-terminal, and if the sub-terminal that has received delegation of usage rights can disclose the content written on the screen, it will display a “Public” display window. If you do not want the content written on the sub-terminal screen to be disclosed, touch the “private” display window to control whether or not to disclose it on the sub-terminal screen.

The open selection of the sub terminal 200 is intended to progress from the previous one-way, closed, one-way communication-centered learning method to a two-way and open communication-centered learning method.

A sub terminal that has been delegated usage rights explains the process or method of solving a problem on the electronic whiteboard through writing or writing content, or approaches the electronic whiteboard directly and explains writing or writing content to the main terminal or other sub terminals. It is configured to enable two-way communication with users of the terminals.

The private selection of the sub terminal means that the sub terminal that has been delegated usage rights communicates only with the main terminal operator, and is intended to progress from a one-way, closed, one-way communication-centered learning method to a two-way, open communication-centered learning method. However, the sub-terminal and the main terminal primarily communicate, and the main terminal collects the opinions of the sub-terminal.

In addition, secondarily, the main terminal explains the problem-solving process or method on the electronic whiteboard through the main terminal screen through writing or writing content, or indirectly by approaching the electronic whiteboard and explaining writing or writing content. This means that it is configured to enable two-way communication with the terminal 200.

Selecting the sub terminal to be private can prevent stress due to social phobia or shyness and encourage smooth learning, as it may be difficult to explain one's intentions depending on the user's personality.

In addition, it is possible to add a priority unit (not marked separately) to the control unit 430. In general, the sub-terminal's electronic whiteboard use authority is only possible when the main terminal's user authority is delegated, making it partially inefficient. Since it may be operational, it is also necessary to improve efficient learning progress through the priority department.

For example, a “proceeding” display window is formed on the screen of the sub-terminal, and when the main terminal operator touches the “proceeding” display window on any of the sub-terminals during the learning process, “proceeding” is displayed on the main terminal operator screen. When the indication is delivered and the main terminal operator touches the “proceeding” sign of the corresponding sub-terminal, the electronic whiteboard use and sharing rights are given priority to the corresponding sub-terminal, so as to ensure efficient learning progress. It is characterized by

The recording unit 440 records all screen information transmitted and output to the electronic whiteboard 300 in real time and stores it in the storage unit 450, and records input information input through the touch screen of the electronic whiteboard 300 in real time. It is recorded and stored in the storage unit 450, and the voice input through the voice acquisition unit of the electronic whiteboard 300 is also stored in the storage unit 450.

The voice acquisition unit can record all voices in surrounding situations, but it is preferable that they are input through a voice input means (not shown) connected to the console box.

It can be operated separately externally in the storage unit 450 in a cloud form, and the stored data can be stored separately by class, time period, and operator, and through this, the stored data can be easily managed.

The recorded screen information stored in the storage unit 450 can be used as repeated learning and review material after learning is completed. By visually exposing the screen information output through the electronic whiteboard 300 and input through an input means such as a touch screen, it is possible to be reminded of the content of the presentation made in class or through the electronic whiteboard, thereby facilitating learning. Improves effectiveness.

In order to control the smart group learning system according to an embodiment of the present invention, an operating application must be installed in each main terminal 100 and sub terminals 200.

Here, when the operating application is configured in the form of a web page, a web server is provided in the console box 400 or a separate web server is provided, and data about shared information set in the web page is transmitted to the web server. You can perform screen sharing with converted parameter values for shared information.

This may vary depending on the number of sub terminals 200 connected to the console box 400. That is, if the number of sub-terminals 200 is large, it is easy to expand the sub-terminal 200 by providing a separate web server, and if the number of server terminals 200 is limited, a web server can be provided and operated within the console box 400. You can.

The operation application controls the console box 400 for operation between the main terminal 100, the sub terminals 200, and the electronic whiteboard 300. By controlling the configuration connected with an Ethernet cable without connecting an external Internet network, buffering or communication interruption due to network problems can be resolved.

The operating application is divided into a main terminal mode and a sub-terminal mode. The main terminal mode has permission to use the electronic whiteboard 300 and share permissions with the sub-terminals 200, and the sub-terminal mode has permission to use the whiteboard 300 and shares permissions with the sub-terminals 200. Sub-terminals 200 in terminal mode may have differentiated rights depending on the user.

Additionally, in order for the main terminal 100 to have sharing authority over the sub terminals 200, the sub terminals 200 connect to a predetermined group to connect to the main terminal 100.

By connecting the sub terminal 200 to a predetermined group, access by others can be prevented, which has the effect of maintaining security for presentation content (class content) provided by the operator.

When the content displayed on the screen of the main terminal 100 is output to the electronic whiteboard 300, the screen information input by the operator of the main terminal 100 through the input means is output to the electronic whiteboard 300 in real time, and the sub It is simultaneously output to the terminals 200.

The main terminal 100 may install an operating application to group sub terminals 200 for each registered user, and share the screens of the grouped sub terminals 200 by selectively mirroring them on the electronic whiteboard 300.

Even if the sub terminals 200 are of the same class, the main terminal 100 can selectively group the sub terminals in a small group concept, and the grouped sub terminals can freely exchange opinions and express their opinions by sharing the screen with each other. This can be done in the form of a discussion.

The right to use the electronic whiteboard 300 is basically given to the main terminal 100, but the right to use the whiteboard 300 can be selectively granted to the sub terminal 200. In this case, the right to use the whiteboard 300 is terminated. no.

In other words, even if the sub terminal has permission to use the electronic whiteboard, the main terminal 100 also has permission to use it, so the main terminal 100 accesses the screen of the sub terminal shared with the electronic whiteboard and performs input such as writing. can be performed.

In more detail, the main terminal 100 may grant permission to use the electronic whiteboard 300 to the selected sub terminal 200 through an operation application.

The reason for granting the sub-terminal 200 permission to use the electronic whiteboard 300 is that the user of the selected sub-terminal 200 can share the screen of the sub-terminal 200 with the electronic whiteboard 300 and directly participate in the problem-solving process. This is to show and explain the problem-solving process to the operator or multiple users based on this, so that they can receive feedback.

The main terminal 100 can operate by specifying the sharing rights of the sub terminals 200 in advance, and can be set by adding a profile.

For example, a profile can be added as shown in FIG. 8, where the screen of the sub terminal 200 PC01 is shared with the sub terminals 200 PC01 to PC07, but the sub terminal 200 PC08 is shared with the sub terminal 200 PC08. Instead of sharing the screen of PC01 of (200), it can be added by specifying that permission to use the electronic whiteboard (300) will be granted to the sub terminal PC01.

As shown in FIG. 9, multiple profiles can be designated and set selectively, saving time during the sharing process.

The console box 400 connects the main terminal 100 and the sub terminals 200 in hardware and outputs screen information from each terminal to the electronic whiteboard 300 so that many people can check it.

The main terminal 100 can individually store academic information according to the user accessing the sub terminal 200. The main terminal 100, the sub terminals 200, the electronic whiteboard 300, and the console box 400 are always connected, so the connection state of each component is always maintained, but is operated according to the user may vary. Classes can be operated and managed depending on the operator or user logging into the application.

For example, user A can access and use the sub terminal 200 over time, or user B can access and use it, so it can be managed according to the accessing user.

That is, users from different time zones can access and use the same sub terminal, and the main terminal 100 can also designate groups by time zone or class.

Accordingly, the present invention has the effect of allowing users to provide interactive feedback by displaying screen information input from a selected sub-terminal rather than only the screen of the main terminal on the electronic whiteboard.

Additionally, the present invention has the effect of preventing buffering or communication interruption through a wired connection within the group and an operation application between devices.

In addition, the present invention has the effect of enabling smooth screen sharing by allowing profiles to be created and managed through an operating application.

In addition, the present invention has the effect of enabling free communication by allowing operators and users to exchange opinions in a conversational format.
