A user account may be required to run the management application. User accounts can be divided into parent accounts and child accounts. Information related to the user account may be stored in the server 100. [

The main functions of the management application can consist of 1) a lock part of an application, 2) a problem solving part, 3) a problem solving part, 4) a problem solving part, 5) a self learning part, and 6) an elimination preventing part. Hereinafter, each of the main functions will be described in detail.

1) the locking portion of the application

FIG. 3 is a flowchart illustrating a lock portion of an application of a child smartphone management method according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step S310, the power of the child smartphone 200b is turned on.

Then, in step S320, the child mode management application locks (deactivates) the designated application so that it can not be executed by the user. A deactivated designated application can be hidden and not displayed on the touch screen. Alternatively, a deactivated designated application may be displayed on the touch screen in a form that is distinct from other applications (such as an icon with a dotted line, opacity, or deactivation label attached). The display method of the deactivated designated application is not limited to the illustrated embodiment.

The parent can use the parent mode management application to view a list of applications installed on the child smartphone 200b, and designate some of them as designated applications. Alternatively, the parent may designate some applications as directed applications by manipulating the child smartphone 200b directly (i.e., using the child mode management application). In this case, the parent would set a password to prevent the child from modifying or deleting the assignment of the designated application.

Subsequently, in step S330, the child mode management application confirms the available time of the user. The usable time indicates the time when the specified application is permitted to execute. The usable time can be recorded in the memory 220. [ The processor 210 may count available time in a predetermined time unit (e.g., in units of one second).

Then, in step S340, the child mode management application determines whether there is a user's available time, and in step S350, if the available time exists, the designated application is locked (activated) so that it can be executed by the user. On the other hand, the child mode management application maintains the locked state of the designated application if the available time does not exist.

Thereby, the user of the child smartphone 200b can execute the designated application until all the available time has been consumed, and can not execute the specified application if the available time is exhausted and no more exists.

2) Problem solving part

4 is a flowchart for explaining a problem solving part of a child smart phone management method according to an embodiment of the present invention.

Referring to FIG. 4, in step S410, the child mode management application locks the designated application so that it can not be executed by the user.

Subsequently, in step S420, the child mode management application downloads the problem of the designated subject and the level (degree of difficulty) from the server 100 to the child smart phone 200b.

Parents can use the parent mode management application to pre-assign the subject and level of the problem. Subjects and levels designated by the parent mode management application may be stored in the server 100. [ In addition, the parent may use the parent mode management application to further specify or set unimportant items or information related to the problem.

The server 100 can search for a parent account matching with the child account, check the specified subject information and designation level information recorded in the parent account, and provide a download of the corresponding problem.

Then, in step S430, the child mode management application displays the downloaded problem on the touch screen, and receives information corresponding to the problem (answer to the problem) from the user. Users can answer questions with multiple choice, answer, essay, or oral. The user can also answer questions by drawing points, lines, faces, shapes, and so on.

Then, in step S440, the child mode management application determines whether the information received from the user satisfies the answer condition of the problem, and if the information received in step S450 satisfies the answer condition of the question, it accumulates the usable time of the user. On the other hand, the child mode management application does not accumulate the user's available time unless the received information satisfies the answer condition of the question. Alternatively, the child mode management application may reduce the usable time of the user.

The available hours to be accumulated can be set differently for each problem. For example, the available hours may be different depending on the subject or level of the problem. Alternatively, the parent may pre-specify the available time to be accumulated using the parent mode management application.

The order of step S410 of locking the designated application and the step of downloading the problem S420 are not limited to the order shown in Fig. 4, and may be changed or performed at the same time in a manner different from the order shown in Fig.

3)

FIG. 5 is a flowchart illustrating a problem-solving part of a child smartphone management method according to an embodiment of the present invention.

Referring to FIG. 5, in step S510, the child mode management application receives some friend smartphone information from the user. The child mode management application can create the friend smartphone list using the contact information stored in the child smart phone 200b. The child mode management application can display the friend smartphone list on the touch screen and receive some smart phone information selected by the user from the friend smart phone list.

Subsequently, in step S520, the child mode management application receives a betting time from the user. The user can input some or all of the accumulated available time as a betting time.

Subsequently, in step S530, the child mode management application requests a battle with the friend smartphone. The problem competition shows that the user's answer satisfies the answer condition in FIG. 4 to solve the problem to the friend smartphone user. Depending on whether the user of the friend smart phone fits the answer to the question, the victory or defeat of the trouble game can be determined. Depending on the result of the win or loss, the user may be able to take away the available time of the other user.

Problems that are used to solve a problem are not necessarily restricted to problems already solved by the user.

Then, in step S540, it is determined whether the information received from the user of the friend smartphone satisfies the answer condition of the question. If the information received in step S550 does not satisfy the answer condition of the question (if the user has won the challenge) Add the usable time of. Then, the usable time of the user of the friend smartphone is reduced by the usable time added to the user.

On the other hand, if the information received in step S560 satisfies the answer condition of the problem (if the user has lost the trouble), the user's usable time is reduced. Then, the usable time of the user of the friend smartphone is added by the usable time reduced to the user.

The available time to be added or subtracted may correspond to the betting time entered by the user. The rank of the user can be determined according to the winning / losing match of the trouble game. And, the available time to be added or subtracted may be increased or decreased depending on the ranking difference of users participating in the problem competition. That is, the betting time may be multiplied by a weight according to the ranking difference.

By applying such a charging method, the user of the child smart phone 200b can be interested in learning related to the child child smart phone management method according to the embodiment of the present invention.

A plurality of users may form a team or a group to perform the above-mentioned competition. In this case, the number of users per team or group may be limited. And, the weight according to the ranking difference may not be considered.

The order of receiving the friend smartphone information S510 and the step S520 of receiving the betting time is not limited to the order shown in Fig. 5, and may be changed or performed at the same time in a manner different from the order shown in Fig.

According to the embodiment, the user inputs the betting time first, the friend of the friend smartphone list having the available time accumulated above the betting time is distinguished and displayed, and the user inputs the friend smartphone information .

In addition, the problem competition is not limited to the battle between the friend smartphone 200b and the child smartphone 200b, but also through the battle ranking (open network). In this case, the child mode management application can access the battle ranking, inquire about a competitor capable of competition, and can generate an opponent list and display it on the touch screen. The user can select a player who wants to play from the list of the opponent, and inputting a betting time, a charging method, compensation according to the charging result, and the like can be applied in a manner substantially similar to that described in the competition with a friend smartphone.

4)

FIG. 6 is a flow chart for explaining a part of a problem diagnosis of a child smartphone management method according to an embodiment of the present invention.

Referring to FIG. 6, in step S610, the child mode management application receives a problem from the user. If the user thinks it is a good problem, he / she can write (or issue) the problem by himself or herself. The user can select and input the subject and level of the problem. The user will be able to make a question with any type of question, such as multiple choice, answer, essay, oral. Then, the child mode management application can provide a plurality of input interfaces suited to the type of each problem that the user issues. The child mode management application can send a problem received from the user to the server 100. [

Subsequently, in step S620, the child mode management application determines whether the score of the problem received from the user is greater than a preset reference score. Problems transmitted to the server 100 may be evaluated and scores may be assigned according to the evaluation results. For example, the server 100 may evaluate a problem received from the user according to a predetermined evaluation factor. The predetermined evaluation factor may include an evaluation by another user. That is, the problem sent to the server 100 can be viewed and evaluated by another user. Evaluation by other users may include numerical evaluation or step-by-step evaluation. Then, the child mode management application can receive scores from the server 100 according to the evaluation results.

Subsequently, in step S630, the child mode management application accumulates the user's point if the evaluation score is greater than the reference score. The user's points can be earned (or proportionally) to the score. The point herein refers to virtual money that can be traded and used in cyberspace rather than real money. These points may be referred to as mileage, coupons, and the like.

At the same time, a problem in which the evaluation score among the problems received from the user is larger than the reference score can be registered in the server 100. [ Problems registered in the server 100 may be provided to other users in the above-described problem solving part or problem playing part.

Subsequently, in step S640, the points accumulated in response to the user's request can be converted into available time, exchanged with an actual price, or used as a payment method of electronic commerce.

In the case of converting accumulated points into usable time, there may be a conversion limit for controlling the usable time. The child mode management application requests the parent smartphone 200a to exchange the accumulated points for the real money, and the amount of the requested points can be returned from the virtual account of the child account. The server 100 provides the shopping mall site, and the user can use the accumulated points as payment means at the shopping mall site.

5) self Learning part

7 is a flowchart illustrating a self-learning part of a child smartphone management method according to an exemplary embodiment of the present invention.

Referring to FIG. 7, in step S710, the child mode management application receives a self-learning plan from a user. The self-learning plan includes goal information and compensation information. The target information represents a learning objective such as a learning amount and an intensity, and the compensation information represents an amount of compensation to be received when the learning objective is achieved. Such a self-learning scheme can be set to a fixed period (e.g., day, week, month, year, etc.).

Subsequently, in step S720, the child mode management application determines whether the user of the parent smart phone 200a has approved the compensation for the user of the child smart phone 200b. The approval of the user of the parent smartphone 200a may include whether to agree on the size of the reward and / or whether to agree to achieve the learning goal. Also, the approval of the user of the parent smartphone 200a may include whether or not the amount corresponding to the compensation is paid. The approval of the user of the parent smartphone 200a may also be performed at a predetermined period as described above.

Then, in step S730, the child mode management application accumulates the user's point corresponding to the compensation information if the user of the parent smart phone 200a approves the compensation.

Then, in step S740, the points accumulated in response to the user's request can be converted into available time, exchanged with an actual price, or used as a payment method of electronic commerce.

As described above, in the case of converting the accumulated points into the usable time, there may be a conversion limit for controlling the usable time. The child mode management application requests the parent smartphone 200a to exchange the accumulated points for the real money, and the amount of the requested points can be returned from the virtual account of the child account. The server 100 provides the shopping mall site, and the user can use the accumulated points as payment means at the shopping mall site.

Although not clearly shown in FIG. 7, the child mode management application can display the compensation information on the touch screen at regular intervals, thereby encouraging the user to learn.

Accordingly, a user of the child smartphone 200b can establish a learning plan by himself or herself and obtains compensation for the learning plan, so that an environment for self-directed learning can be created.

6)

8 is a flowchart illustrating an anti-removal part of a child smartphone management method according to an embodiment of the present invention.

Referring to FIG. 8, in step S810, the child mode management application detects a removal request by a user of the smartphone.

Then, in step S820, the child mode management application resets the accumulated usage time and / or point of the user.

Subsequently, in step S830, the child mode management application notifies the parent smart phone 200a of the detection result of the removal request of the user of the child smart phone 200b.

Subsequently, in step S840 (when the child mode management application is removed despite the above steps), the server 100 transmits the installation path of the management application to the child smart phone 200b using a push message or the like .

This can substantially prevent the removal of the application even in the case of the operating system of the smartphone, which is impossible to set to restrict the removal of the application.

On the other hand, the management application may include an interface for transmitting and receiving data with other learning applications. The user can use the learning contents provided by the other learning application without using the learning contents provided by the management application and can accumulate the usable time or points by compensating the learning contents provided by the other learning application. To this end, the management application can receive learning information such as the amount of learning content and progress of learning contents from other learning applications. That is, the management application can also accumulate availability time or points in a manner similar to the above-described problem solving or self-learning plan for use of other learning applications.

The steps of a method or algorithm described in connection with the embodiments of the invention may be embodied directly in hardware, software modules, or a combination of the two, executed by a processor. The software modules may be stored in any form of computer readable storage medium such as a random access memory (RAM), read-only memory (ROM), EPROM, EEPROM, flash memory, registers, hard disk, removable disk, CD- Or may reside on a recording medium. An exemplary recording medium is coupled to a processor, which is capable of reading information from, and writing information to, the recording medium. Alternatively, the recording medium may be integral with the processor. The processor and the recording medium may reside in an application specific integrated circuit (ASIC). The ASIC may reside within the user terminal. Alternatively, the processor and the recording medium may reside as discrete components in a user terminal.

Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, those skilled in the art will appreciate that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
