Fig. 1 is a diagram showing an arithmetic learning system according to an embodiment of the present invention.
The arithmetic learning system according to an embodiment of the present invention may include the arithmetic learning apparatus 100, the terminal device 200, and the server device 300.
First, the arithmetic learning apparatus 100 according to the embodiment of the present invention is a training aid for arithmetic operation learning by a user. The arithmetic learning apparatus 100 is implemented in the shape of a hexahedron, and each face of the hexahedron includes a button that can be manipulated by a user. At least one of a specific numerical value and a functional mode is set to each of the buttons. The arithmetic learning device 100 provides an arithmetic question in an audible or visible manner according to button manipulation by a user, and the user inputs an answer to the arithmetic question by manipulating the button.

Fig. 2 is a configuration diagram of an arithmetic learning apparatus according to an embodiment of the present invention.
The arithmetic learning apparatus 100 according to an embodiment of the present invention may include a main body 110, a light emitting module 120, a speaker 130, and a microcontroller 140, and may further include a communication module 150 and a charging module 160.
The body 110 is implemented in a hexahedral shape. A space in which devices necessary for driving the arithmetic learning apparatus 100, such as the light emitting module 120, the speaker 130, and the microcontroller 140, can be provided may be formed inside the main body 110. The body 110 may be implemented using a plastic material, or may be implemented using another material. However, when the main body 110 is implemented using a plastic material, the weight of the arithmetic learning apparatus 100 may be reduced, so that user convenience may be improved.
Each face of the hexahedral body 110 may be divided into a predetermined number of regions, and buttons are provided for each of the divided regions. For example, when each face of the body 110 is divided into 3 × 3 areas (i.e., nine areas), nine buttons are disposed on each face, and 54 buttons are disposed on the entire body 110. The button may be implemented using a silicone material, or may be implemented using another material. However, when the button is implemented using a silicone material, a tactile sensation felt by a user when manipulating the button may be improved.
A numerical value corresponding to the arithmetic calculation result according to a predetermined rule may be displayed on the button. For example, the arithmetic calculation result according to the predetermined rule may be a result value obtained by multiplying a first numerical value selected from the numerical values 1 to 9 by a second numerical value selected from the numerical values 1 to 9, i.e., one of the numerical values included in the multiplication table.
The function mode may be further displayed on a button provided on one of the six faces of the hexahedral body 110. The functional modes may include a learning mode including at least one of addition learning, subtraction learning, multiplication learning, and division learning, and a difficulty selection mode for selecting a difficulty level of the learning mode. The learning mode may further include song arithmetic learning for providing a learning problem by song. In addition, the functional modes may further include a power mode for turning on and off the arithmetic learning apparatus 100, a sleep light mode in which the light emitting element emits light, and the like.
The light emitting module 120 is provided to correspond to the button, and allows the light emitting element corresponding to the pressed button to emit light. For example, when a total of 54 buttons are disposed on the main body 110, the light emitting module 120 may be disposed to correspond to each of the 54 buttons. Next, when a button of the 54 buttons is pressed by the user, the light emitting module 120 allows the light emitting element corresponding to the pressed button to emit light. Further, when a button corresponding to a light emitting element that emits light is pressed, the light emitting module 120 may allow light emission of the light emitting element corresponding to the pressed button to be terminated. That is, the light emitting module 120 may allow the corresponding light emitting element to emit light by manipulating the button, or allow light emission of the light emitting element to be terminated. In addition, the light emitting module 120 may allow all or some of the light emitting elements to emit light according to a predetermined pattern in the control according to the sleep light pattern. The light emitting element may be a Light Emitting Diode (LED), but the present invention is not limited thereto.
The speaker 130 is provided in the main body 110, and outputs the learning question to the user.
Specifically, speaker 130 outputs acoustic signals received from microcontroller 140. In this case, the acoustic signal may be a signal related to a learning problem, or may be a signal related to the operation of the arithmetic learning apparatus 100.
The microcontroller 140 is provided in the main body 110, and controls the overall operation of the arithmetic learning apparatus 100 including the main body 110, the light emitting module 120, the speaker 130, and the communication module 150.
According to an embodiment of the present invention, the microcontroller 140 may operate a functional mode set to the button according to the button manipulation.
Specifically, when a button having a function mode displayed thereon is pressed according to a preset pattern, the microcontroller 140 may operate the function mode set to the pressed button according to the preset pattern. For example, when a button is pressed and held for three seconds or longer, the microcontroller 140 may run a functional mode set to the corresponding button.
When a difficulty selection mode of the learning mode and the functional mode is operated, the microcontroller 140 selects a learning question selected from a question database storing learning questions to correspond to the learning mode and the difficulty level, and provides the selected learning question to the user.
When the selected learning question is provided to the user and then the button corresponding to the provided learning question is pressed, the microcontroller 140 determines whether the numerical value displayed on the pressed button matches the correct answer to the provided learning question and then provides the result of the determination to the user. For example, the microcontroller 140 may notify the user through the speaker 130 whether the input answer is correct.
Specifically, when it is determined that the value matches the correct answer (i.e., when the input answer is correct), the microcontroller 140 provides a subsequent learning question (when an additional learning question needs to be provided), or terminates the provision of the learning question (when an additional learning question does not need to be provided). In this case, the microcontroller 140 may together output a voice message (e.g., a pop-up voice, etc.) indicating that the learning problem has been solved.
On the other hand, when it is determined that the value does not match the correct answer (i.e., when the input answer is wrong), the microcontroller 140 outputs a request for re-inputting the answer to the provided learning question, and provides a subsequent learning question or terminates the provision of the learning question when the value displayed on the pressed button does not match the correct answer to the provided learning question after re-inputting for a preset number of times.
In the case of selecting the first difficulty level of the song arithmetic learning, the microcontroller 140 may turn on the light emission placed on the button corresponding to the correct answer to the learning question provided by the song, and when the button whose light is turned on is pressed, control the light of the pressed button to be turned off.
In the case of selecting the second difficulty level of the song arithmetic learning, when a button corresponding to a correct answer to the learning question provided by the song is pressed, the microcontroller 140 may control the light emission of the pressed button to be turned on.
In the case where the third difficulty level of the song arithmetic learning is selected, when a button corresponding to the learning question provided by the song and a button corresponding to the correct answer are sequentially pressed, the microcontroller 140 may determine that the learning question provided by the song is solved.
A preset completion condition may be set for the learning mode of each difficulty level. When preset completion conditions for all difficulty levels of all learning types included in the learning mode are satisfied, the microcontroller 140 may provide the learning problem to the user according to the final learning mode.
The communication module 150 is provided in the main body 110, and communicates with the terminal device 200 in which the application program is installed.
The communication module 150 may be implemented as a bluetooth type communication module 150, but the present invention is not limited thereto. The communication module 150 may be a Local Area Network (LAN) type communication module 150, a Wi-Fi type communication module 150, or a communication module 150 using another communication method.
The charging module 160 is disposed in the main body 110, and charges a built-in battery. The charging module 160 may include a charging terminal and a battery. The battery may be a lithium polymer battery, but the present invention is not limited thereto. According to an embodiment of the present invention, the charging terminal may be a Universal Serial Bus (USB) type C terminal. However, the present invention is not limited thereto, and the charging terminal may be any one of a micro-USB 11-pin terminal, a lightning (lightning) terminal, and a micro-USB 5-pin terminal.
Although not shown in the drawings, the arithmetic learning apparatus according to the embodiment of the present invention may further include a cover member (not shown). The cover member may cover an outside of the main body. Specifically, the cover member may cover an edge portion of the main body except for the button portion of the main body. The cover member may be implemented in a detachable structure, may be implemented with a material such as urethane, and may be implemented in various colors. According to the embodiments of the present invention, due to the cover member, a user's grip feeling when using the arithmetic learning apparatus 100 can be improved, external impact applied to the main body can be mitigated, and visual satisfaction can be improved by color change.

As shown in fig. 3 and 4, the arithmetic learning apparatus 100 according to the embodiment of the present invention includes a hexahedral body 110.
As illustrated in fig. 3, the body 110 may be implemented in a regular hexahedral shape among hexahedral shapes. The vertices and corners of the body 110 may be rounded to have a certain curvature. Therefore, an accident that may occur in using the arithmetic learning apparatus 100 can be prevented. Next, an opening may be formed in a corner portion of the main body 110 so that a sound output from the speaker 130 provided in the main body 110 may be output through the opening. Next, an opening through which an external charging interface may be connected to the charging terminal may be formed on one face of the hexahedron.
For each divided region, a button may be disposed on each side of the body 110. In fig. 3, each face is divided into regions to have a 3 × 3 matrix form, and a button is provided in each of the regions.

Fig. 7 is a configuration diagram of a terminal apparatus according to an embodiment of the present invention.
As shown in fig. 7, the terminal device 200 according to an embodiment of the present invention may include a question providing unit 210, a learning analysis unit 220, an incorrect answer reviewing unit 230, and a ranking output unit 240.
The question providing unit 210 selects a learning question of the final learning mode provided to the arithmetic learning apparatus 100 from a question providing database storing the learning questions provided to the arithmetic learning apparatus 100, and provides the selected learning question to the arithmetic learning apparatus 100. In this case, the question providing database may be updated by the server device 300.
The question providing unit 210 may randomly select a learning question from the question providing database and provide the selected learning question to the arithmetic learning apparatus 100. Further, the question providing unit 210 may receive at least one piece of information including a type of learning question, a difficulty level, and a number of questions, select a learning question from the question providing database based on the received information, and provide the selected learning question to the arithmetic learning apparatus 100. For example, when the question providing unit 210 receives pieces of information including the type of learning question including subtraction and multiplication, the high and medium difficulty levels, and the number of questions of ten, the question providing unit 210 may select ten questions from the group of questions having the high and medium difficulty levels of the subtraction and multiplication learning questions, and provide the selected questions to the arithmetic learning apparatus 100.
The problem providing unit 210 may further receive a compensation item provided when the final learning mode is completed. For example, in the case where a bicycle is provided as compensation when the final learning mode is completed, a picture of the bicycle to be provided may be input as a compensation item.
The learning analysis unit 220 analyzes the learning achievement of the arithmetic learning device 100 for each learning pattern based on the learning result information received from the arithmetic learning device.
For example, the learning analysis unit 220 may analyze learning achievement according to the correct answer rate and the question solving time for each learning pattern. As another example, the learning analysis unit 220 may analyze the learning outcome according to the correct answer rate and the question solving time for each day or for each learning.
The wrong-answer reviewing unit 230 generates a wrong-answer database storing learning questions to which wrong answers are input based on the learning result information, selects at least one learning question from the wrong-answer database, and provides the selected learning question to the arithmetic learning apparatus 100.
The wrong-answer reviewing unit 230 may randomly select a learning question from the wrong-answer database and provide the selected learning question to the arithmetic learning apparatus 100. Further, the wrong-answer reviewing unit 230 may receive at least one piece of information including a type of learning question, a difficulty level, and the number of questions, select a learning question from the wrong-answer database based on the received information, and provide the selected learning question to the arithmetic learning apparatus 100.
To this end, the arithmetic learning device 100 may further include a learning mode for solving the learning question provided by the wrong answer reviewing unit 230. For example, since the question is provided through the speaker 130, when the learning question provided by the wrong answer reviewing unit 230 is received, the arithmetic learning apparatus 100 may output a message indicating that the learning is continued by pressing a specific button, and the user may press a specific button of the arithmetic learning apparatus 100 to continue the learning.
Meanwhile, the wrong answer reviewing unit 230 may provide the learning question stored in the wrong answer data on the display. For example, when a guardian (parent) selects a frequently incorrectly answered question, the wrong-answer reviewing unit 230 may output the corresponding question stored in the wrong-answer database on a display. The guardian can then teach his or her child about the corresponding learning problem by viewing the outputted learning problem.
The ranking output unit 240 outputs a ranking according to a score calculated based on the learning result information.
The ranking output unit 240 outputs a ranking of scores calculated according to a region set by a user. For example, when "korea seoul ma" is set as the residential zone by the user, the ranking of the user who lives in "korea seoul ma" is output. Information regarding the ranking may be received from the server device 300.
Further, the ranking output unit 240 may output a ranking according to the learning mode completion states of all users in the region set by the user. For example, when the user completes the learning procedure having the first to third difficulty levels of the specific learning mode using the arithmetic learning apparatus 100, the terminal device 200 may provide the cube item corresponding to the specific learning mode. The cube items may include an addition cube item indicating that addition learning for all difficulty levels has been completed, a subtraction cube item indicating that subtraction learning for all difficulty levels has been completed, a multiplication cube item indicating that multiplication learning for all difficulty levels has been completed, a division cube item indicating that division learning for all difficulty levels has been completed, a multiplication table cube item indicating that song arithmetic learning for all difficulty levels has been completed, and a master cube item indicating that a final learning mode has been completed. Accordingly, the user may have different numerical cube items collected according to the completion degree of learning, and the ranking output unit 240 may output the ranking of the user according to the numerical values of the cube items to be obtained in the setting region.
Fig. 8 is a flowchart for describing a first example of an operation process of the arithmetic learning apparatus according to the embodiment of the present invention.
First, the arithmetic learning device 100 receives a learning mode by being pressed a button according to a preset manner (S605). For example, when the user presses the second button on the first face on which the learning mode for the addition learning is set for two seconds, the arithmetic learning apparatus 100 receives and executes the learning mode for the addition learning.
Next, the arithmetic learning device 100 receives a difficult selection mode by being pressed a button according to a preset manner (S610). For example, when the user presses the third button on the first face of the setting difficulty selection mode for two seconds and then presses the third button, the arithmetic learning apparatus 100 receives the third difficulty level.
Next, the arithmetic learning device 100 determines whether a condition of the difficulty level for performing reception is satisfied (S615). For example, when the addition learning of the third difficulty level is input, the arithmetic learning apparatus 100 determines whether the problem of the second difficulty level of the addition learning which is the execution condition of the third difficulty level is completed.
When it is determined that the condition for performing the received difficulty level is not satisfied, the arithmetic learning apparatus 100 requests re-input of the difficulty level (S620) and then receives the difficulty level again from the user.
On the other hand, when it is determined that the condition for performing the received difficulty level is satisfied, the arithmetic learning device 100 provides the learning problem of the corresponding difficulty level of the corresponding learning mode (S625).
Meanwhile, instead of operating S610 to S620, the arithmetic learning device 100 may provide a learning problem of a learning mode with an input of a preset difficulty level. Here, the preset difficulty level refers to the highest difficulty level that the user can currently select. For example, when the user completes the problem of the first difficulty level of the additive learning and thus enters a state in which the user can receive the problem of the second difficulty level, the arithmetic learning apparatus 100 may provide the learning problem of the second difficulty level when the user selects the additive learning.
Alternatively, the arithmetic learning device 100 may receive the difficulty level by activating only the input of the user-selectable difficulty level.
Tables 1 to 4 below are examples of learning problems of previously stored learning patterns for each difficulty level. Table 1 is an example of a learning problem of multiplication learning for each difficulty level, table 2 is an example of a learning problem of division learning for each difficulty level, table 3 is an example of a learning problem of addition learning for each difficulty level, and table 4 is an example of a learning problem of subtraction learning for each difficulty level. Tables 1-4 are merely examples and may be modified by one of ordinary skill in the art.

[ Table 4]
The arithmetic learning apparatus 100 selects a learning question corresponding to the selected learning mode and difficulty level (as shown in the above table) from a question database storing learning questions, and provides the selected learning question to the user.
When the selected learning question is provided to the user and then the button corresponding to the provided learning question is pressed (S630), the arithmetic learning device 100 determines whether the numerical value displayed on the pressed button matches the correct answer to the provided learning question (S635).
When it is determined that the numerical value matches the correct answer (i.e., when the input answer is correct), the arithmetic learning device 100 provides a subsequent learning question (when an additional learning question needs to be provided), or terminates the provision of the learning question (when an additional learning question does not need to be provided) (S640). For example, the arithmetic learning apparatus 100 may provide ten learning questions of the third difficulty level of the learning pattern relating to the additive learning. When ten learning questions are not all provided, the arithmetic learning apparatus 100 may provide the learning questions that are not provided. In this case, the arithmetic learning device 100 may output together a voice message (e.g., a pop voice, etc.) indicating that the learning problem has been solved.
On the other hand, when it is determined that the numeric value does not match the correct answer (i.e., when the input answer is wrong), the arithmetic learning apparatus 100 determines whether the numeric value of the input wrong answer exceeds a preset numeric value (S645).
When it is determined that the value of the input wrong answer exceeds the preset value, the arithmetic learning apparatus 100 provides a subsequent learning question (when an additional learning question needs to be provided), or terminates the provision of the learning question (when an additional learning question does not need to be provided).
On the other hand, when it is determined that the inputted numerical value of the wrong answer does not exceed the preset numerical value, the arithmetic learning apparatus 100 outputs a request for re-inputting the provided answer to the learning question and receives the answer to the question again.
Meanwhile, after the provision of the question is terminated, it is determined whether the completion condition of the corresponding difficulty level for the corresponding learning mode is satisfied. In this case, the completion condition may be set based on the time required to solve the provided learning question and the correct answer rate. For example, when the required time is not more than three minutes and the correct answer rate is more than 60%, a question of the second difficulty level to complete the learning mode related to the additive learning may be determined. Alternatively, when the cumulative learning time of the corresponding difficulty level exceeds 20 minutes and the correct answer rate of the previous 20 questions exceeds 80%, it may be determined that the questions of the corresponding difficulty level are completed. When the corresponding condition is satisfied, even while learning is in progress, a sound such as "upgrade" may be output to notify the user that the problem of the corresponding difficulty level has been completed.
Fig. 9 is a flowchart for describing a second example of an operation process of the arithmetic learning apparatus according to the embodiment of the present invention.
According to an embodiment of the present invention, the learning mode may further include song arithmetic learning in addition to the addition learning, the subtraction learning, the multiplication learning, and the division learning. Song arithmetic learning is a learning method that provides a learning problem by a method of combining songs, lighting, and button input. Song arithmetic learning may be a learning method of providing a learning question through a song and inputting a correct answer according to the provided song.
Referring to fig. 9, the arithmetic learning apparatus 100 receives a learning pattern related to song arithmetic learning (S705), and then receives a difficulty level through a difficulty selection pattern (S710). Next, the arithmetic learning apparatus 100 determines whether a condition of the difficulty level for performing reception is satisfied (S715). When it is determined that the condition for performing the received difficulty level is not satisfied, the arithmetic learning apparatus 100 requests re-input of the difficulty level (S720) and then receives the difficulty level again. On the other hand, when it is determined that the condition for performing the received difficulty level is satisfied, the arithmetic learning apparatus 100 provides a learning problem of the corresponding difficulty level of the learning pattern relating to the song arithmetic learning.
Meanwhile, instead of performing S710 to S720, the arithmetic learning device 100 may provide a learning problem of a learning mode with an input of a preset difficulty level. Here, the preset difficulty level refers to the highest difficulty level that the user can select at the present time. For example, when the user completes the problem of the first difficulty level of the arithmetic learning of the song and thus enters a state in which the user can receive the problem of the second difficulty level, the arithmetic learning apparatus 100 may provide the learning problem of the second difficulty level when the user selects the arithmetic learning of the song.
Alternatively, the arithmetic learning device 100 may receive the difficulty level by activating only the user-selectable input of the difficulty level.
In this case, in the case where the first difficulty level of the arithmetic learning of the song is selected, the arithmetic learning apparatus 100 controls all the lights provided on the button corresponding to the correct answer to the learning question provided by the song to be turned on (S725). When the button to turn on the light emission is pressed, the arithmetic learning device 100 controls all the light emission of the pressed button to be turned off (S730). For example, when providing the lyrics "2 by 1 is? "and then the button having the numerical value 2 displayed as the correct answer is pressed within a predetermined time, the arithmetic learning apparatus 100 may terminate the light emission of the light emitting element provided in the button having the displayed numerical value 2. When the button having the displayed numerical value 2 is not pressed within the predetermined time, the light emission may not be terminated.
In the case where the second difficulty level of the arithmetic learning of the song is selected, the arithmetic learning device 100 terminates the light emission of all the light emitting elements (S735), and then when the button corresponding to the correct answer to the learning question provided by the song is pressed, the arithmetic learning device 100 controls the light emission of the pressed button to be turned off (S740). For example, when providing lyrics "3 by 8 is? "and then presses the button having the numerical value 24 displayed as the correct answer within a predetermined time, the arithmetic learning device 100 may control the light emitting element provided in the button having the displayed numerical value 24 to emit light.
Next, in a case where the third difficulty level of the arithmetic learning of the song is selected, when the button corresponding to the learning question provided by the song and the button corresponding to the correct answer are sequentially pressed, the arithmetic learning device 100 determines that the learning question provided by the song is solved (S745). For example, when a song is provided in a state where all the light emitting elements of the arithmetic learning apparatus 100 are turned off, the user can press a button corresponding to any numerical value from the song and a button corresponding to a correct answer to the learning question.
Meanwhile, the contents of the first to third difficulty ratings are examples, and the runs S735 and S740 having the second difficulty rating may be runs S725 and S730 having the first difficulty rating.
Fig. 10 is a flowchart for describing a third example of the operation process of the arithmetic learning apparatus according to the embodiment of the present invention.
For example, when preset completion conditions of all difficulty levels of the addition learning, the subtraction learning, the multiplication learning, the division learning, and the song arithmetic learning are satisfied in the learning mode, the arithmetic learning apparatus 100 may provide the learning problem to the user according to the final learning mode.
Referring to fig. 10, when the final learning mode is input (S805), the arithmetic learning apparatus 100 determines whether preset completion conditions for all difficulty levels are satisfied in all learning types included in the learning mode (S810).
When it is determined that the preset completion condition is satisfied, the arithmetic learning device 100 provides the learning problem according to the final learning mode to the user (S815). On the other hand, when it is determined that the predetermined completion condition is not satisfied, the arithmetic learning device 100 may notify the user that the completion condition is not satisfied, and then terminate the operation or input "try again" according to the final learning mode (S820).
