In the various embodiments described below, when a learner frees problems printed in a question book on which codes are printed, and then scored using a smart pen, a mobile device interfaced with the smartpen displays a graphical user interface (GUI) Graphical user interface) to provide feedback that is helpful to learners such as incorrect answer notes.

FIG. 1 is a diagram for explaining a connection relationship between a smart pen, a mobile device and a server, FIG. 2 is a diagram illustrating a hardware configuration of a smart pen, and FIG. 3 is a diagram illustrating a hardware configuration of a mobile device.

The learner learns by using a printed matter 40 such as a problem book, a textbook or a blank note, and uses the smartpen 20. [ In the printed matter 40, a plurality of codes that the smartpen 20 can recognize are finely printed. Even if it is a blank note, a large number of codes are printed using a color or a special pigment which is hard to be visually recognized in the microscopic size or difficult to be visually recognized by the naked eye.

Such a code may be evenly printed over the entire margin of the paper, apart from contents such as texts and images that the learner can perceive visually, and includes predetermined information.

The smart pen 20 has a built-in writing instrument such as a ballpoint pen so that it can be written or drawn on paper. When the user selects or writes a pencil on the printed matter, the smart pen 20 transmits information for reading the coordinates etc. to the mobile device 10 Lt; / RTI >

2, the smart pen 20 may include a pressure sensing sensor 21, a camera 22, and a short range communication module 23.

The pressure sensing sensor 21 senses the pressure applied to the pen tip. That is, when the user grasps the smart pen 20 and performs an operation such as writing a handwriting, drawing a picture, or tapping on a printed matter to select it.

The camera 22 captures a code printed on the printed matter 40. [

The short range communication module 23 is a means for communicating with the mobile device 10, preferably a wireless communication adapter by a short range wireless communication protocol such as Bluetooth.

Upon reception of the information from the smart pen 20, the mobile device 10 switches to the incorrect processing mode, judges whether the problems printed on the printed matter are incorrect according to the user's operation, It is a device for displaying a wrong answer note containing information to the user.

3, the mobile device 10 may include a processor 11, a display 12, a smartpen interlocking means 13, and a communication means 14.

The processor 11 executes the instructions stored in the computer program and executes the computer program recorded on the recording medium to perform the method of providing the incorrect answer according to the present invention.

The display 12 may have a touch panel and display information in a visual form. A known touch screen, a liquid crystal display (LCD), a light emitting diode (LED), or the like.

The smart pen interlocking means 13 is a means for communicating with the smart pen 20, preferably a wireless communication adapter conforming to a known standard such as Bluetooth.

The communication means 14 is for communicating with the server 30 through the Internet network, and may be an Ethernet adapter or an adapter according to a known wire / wireless communication standard such as a WiFi adapter.

Meanwhile, the mobile device 10 may be in the form of a known smart phone, a tablet computer, a laptop computer or the like, and is not limited to the form or name as long as the above description is satisfied.

The server 30 is a device for receiving a request for generating a wrong answer note from a plurality of mobile devices 10 connected via an Internet network or the like and generating a wrong answer note for each user and transmitting the generated note to the mobile device 10.

As shown in FIG. 1, when a learner performs learning while the printed matter 40 is opened and solves printed problems and then performs a predetermined operation using the smart pen 20, the smart pen 20 , The mobile device 10 recognizes that the learner performs scoring and judges which problem is hit and which one is wrong, and processes the wrong answer including the wrong answer and the correct answer.

The configuration of the mobile device 10 that processes user input through the smart pen 20 in conjunction with the smart pen 20 will be described in detail below.

The processor 11 obtains the book identifier and the page information and the coordinate value on the printed matter in cooperation with the smart pen 20 as the smart pen 20 recognizes the code printed on the printed matter 40. [

The code may be implemented as a combination of a plurality of dots, and different information is represented according to the separation distance of each dot. These dots are printed with very fine or difficult-to-identify colors, so they do not block the view.

Preferably, a code indicative of a book identifier may be printed on all pages of the printed matter 40 at regular intervals. All pages in relation to the book identifier have the same code.

In addition, a code indicating the page information (that is, information indicating how many pages the page is) may be printed on each page at regular intervals. With respect to page information, every page has a different code.

On the other hand, a code indicating coordinates is printed on all the pages. Coordinates can be expressed in the form of codes in pairs of x and y values. Regarding the coordinate values, preferably the same code is printed at the same position on all pages.

When the smart pen 20 recognizes the printed code and transmits it to the mobile device 10, the processor 11 of the mobile device 10 reads the printed material identification information page information and the coordinate information from the received code, And determines which action is to be performed in response thereto.

The action may be implemented in the form of an API (Application Program Interface) function provided by the server 30 and may be included as a command to call the corresponding API in the computer program loaded in the mobile device 10. [

The instructions executed by the processor 11 may be stored in the form of a computer program and stored locally. At this time, actions corresponding to specific coordinates of a specific page are predefined and stored in the book setting information of the corresponding printed matter.

No action needs to be defined for every coordinate of every page.

An action may be defined and assigned to a specific position of the printed matter 40 or an action may be defined and assigned to a certain coordinate area or an arbitrary action may be defined by default at the remaining positions except for a specific position.

Of course, there may be sections where the action is not defined at all.

On the other hand, the processor 11 determines and executes an action to be executed corresponding to the code recognized by the smart pen 20, and displays the result on the display 12. If the action is not defined, the process is terminated without performing another action.

Hereinafter, a method of providing a wrong answer note using the smart pen 20 will be described in detail.

The method of providing a wrong answer using the smart pen according to the present invention can be executed in the mobile device 10 connected to the smart pen 20 and the server 30 by wire / wireless communication as shown in FIG.

4 is a flowchart illustrating a process of a method for providing a wrong answer using a smart pen according to the present invention.

The learner pairs the smartpen 20 with the mobile device 10 prior to learning. Thereafter, the smartpen 20 can recognize the code through the camera 22 when the printed matter 40 is unfolded to solve the problem and an arbitrary point on the printed matter is pressed or drawn with the pen tip of the smart pen 20 do.

4, the mobile device 10 acquires the coordinate information related to the code recognized from the smart pen 20 as the paired smart pen 20 recognizes the code printed on the printed matter 40 (S42). At this time, the identification information of the printed matter 40 and the page information of the position selected by the learner will also be obtained.

For example, the identification information of the printed matter 40 may be information indicating a question paper of a specific subject. If the question paper is more than two pages, the page information is information indicating the number of pages in the entire page of the question paper.

Meanwhile, the mobile device 10 determines which operation mode is currently being operated (S44). In the case of the incorrect answer processing mode, the page information according to the code recognized by the smart pen 20 and the function corresponding to the coordinate information are fetched from the book setting information, and if the fetched function is a mode change, the mode is changed to the wrong answer processing mode ). That is, if the learner performs an operation in accordance with a predetermined appointment, such as selecting a predetermined position by using the smart pen 20 or starting a handwriting, it recognizes it as a mode change command and changes to an incorrect answer processing mode, will be.

FIG. 5 is a diagram illustrating a printed matter (problem sheet) including problems and a situation in which a learner marks a problem with a smart pen.

Referring to FIG. 5, a plurality of problems are printed on the question paper, and a separate question mark area 51 for checking whether or not an error has occurred is printed. The scoring area 51 includes sub areas corresponding to each problem.

The change to the incorrect answer processing mode can be performed in various ways, and the mode in which the mode is changed when an input is received from the smart pen 20 can be defined in the book setting information of the corresponding printed matter.

In the example of Fig. 5, an area 56 informing the start of grading is provided separately at the lower end of the question paper. When the learner brings the pen tip of the smart pen 20 to the scoring start notification area 56 after the learner has solved the problem, the mobile device 10 will convert to the wrong answer processing mode.

As another example, when the smart pen 20 is placed at an arbitrary position on the page where the problems are printed or the handwriting is started, instead of changing to the wrong answer processing mode when the predetermined position is pressed as shown in FIG. 5, It is possible to change to the wrong answer processing mode.

As another example, when the pen tip of the smart pen 20 is pressed in one sub area of the scoring area 51 for checking an incorrect answer, it may be changed to an incorrect answer processing mode. In this case, the mobile device 10 changes to the error-correcting mode and processes the sub-area selected by the user, that is, the problem corresponding to the received coordinate information, as an incorrect answer.

Referring again to FIG. 4, if the app of the mobile device 10 has already been changed to the incorrect processing mode, it is determined whether or not a problem corresponding to the coordinate information obtained through the smart pen 20 is wrong (S48).

5, the sub area corresponding to each problem is included in the scoring area 51. When the sub area (s) corresponding to the wrong problem is photographed by the smart pen 20, the mobile device 10 displays the corresponding problem ) As an incorrect answer.

On the other hand, if there is no wrong problem, if the wrong answer area 53 is photographed with the smart pen 20, the mobile device 10 recognizes that the learner has met all the problems, It is possible to provide additional learning information such as an in-depth problem to a learner who has no wrong answer by confirming that the function is defined in the book setting information.

When the learner finishes scoring and the wrong answer region 52 is drawn with the smart pen 20, a wrong answer note including information related to the wrong question (s) is generated (S50). The wrong answer note may be generated using the data stored locally by the mobile device 10, but may also request a wrong answer note by sending a wrong problem number to the server 30. The subject performing the function corresponding to the wrong answer note processing can be determined as defined in the book setting information.

6 is a flowchart illustrating a process of the server generating a wrong answer note in accordance with an embodiment of the present invention.

Referring to FIG. 6, the mobile device 10 transmits the learner's user information and a result of determining an incorrect answer for each question to the server 30 (S501).

The server 30 generates a wrong answer note including the correct answer of the wrong question and a solving process and sends it to the mobile device 10 or transmits a URL (Uniform Resource Locator) to access the wrong answer note page (S502) If the mobile device 10 receives the URL, it accesses the corresponding address and receives the wrong answer note (S503).

The wrong answer note generated by the mobile device 10 or the server 30 is displayed on the display 12 of the mobile device 10 (S52).

FIG. 7 illustrates an example of a wrong answer according to an embodiment of the present invention.

Referring to FIG. 7, the incorrect answer note 60 may include context information 61 including information about the printed matter and the page, and a learner's wrong problem and correct answer. The learner can print the wrong answer note by clicking the 'print' button 62 and click on the 'additional information' button 63 to obtain additional learning information about the wrong problems. In addition, if a deletion icon 64 for each problem is clicked before printing or additional information on the incorrect answer note is viewed, the problem that the learner does not want is deleted.

FIG. 8 shows another example in which a learner marks a problem with a smart pen.

Referring to FIG. 8, there is not a scoring area for marking each question or checking for an incorrect answer, but a mark or a slash is directly drawn on the number part of each question with the smart pen 20 to score.

The scoring area 70 shown in Fig. 8 is not an area that is printed visually on the question paper but is an area defined by the book setting information. That is, in the book setting information, at least a part of the area where each question is printed may be defined as a scoring area 70. [

When the learner draws something on the question paper with the smart pen 20, the mobile device 10 refers to the book setting information to determine which coordinate information corresponding to the question mark area of the question is received. Further, the learner recognizes the gesture drawn through the smart pen 20, and judges whether the problem is the right answer or the correct answer according to the type of the recognized gesture. In this case, the circle display conventionally used by the learner can be recognized as a correct answer with the X mark or the / mark as an incorrect answer, so that the learner can automatically score on the mobile device 10 You can get the generated wrong answer note.

Referring to FIG. 8, when the learner marks the problem 1 and the problem 3 as wrong and the bad answer region 73 is photographed, the mobile device 10 displays a list of the problems (Problem 1, Problem 3) Will be performed to generate a wrong answer note containing information.

FIG. 9 shows an example of a wrong answer note generated as a result of scoring according to FIG.

Referring to FIG. 9, the incorrect answer note 80 may include context information 81 including information about the printed matter and the page, correct answer of the wrong question by the learner, and a solving process. The learner can print the wrong answer note by clicking the 'print' button 83 and click the 'commentary lecture' button 63 to hear a lecture on the wrong problems.

In addition, if a note necessary for a learner is input in the note field 82 before printing the wrong answer note, the system can obtain a wrong answer note added to the incorrect answer note automatically generated by the learner himself / herself.

On the other hand, if the learner erroneously solves the problem using the printed wrong answer note, the learner may not be able to score the question through the same process as described above. have.

This is a problem that is solved by solving problems using printed materials rather than solving problems in a digital environment.

To solve this problem, the following two methods can be used.

The first is to print a separate problem unique key for each question on the questionnaire. That is, the identification information of the printed matter is printed on the entire printed page 40 in an arbitrary page. Separately, the unique key in question is printed for each area occupied by each problem.

In this case, instead of determining that the problem corresponding to the coordinates recognized by the smart pen 20 is incorrect, the unique key of the problem is recognized by the smart pen 20 and transmitted to the mobile device 10 for scoring. Thus, a learner can have a unique key of a wrong problem so that a learner can identify and track which problem is repeatedly wrong.

However, this method has a disadvantage in that it is not easy to post-correct because different keys must be physically printed for each problem.

Alternatively, a unique key may be assigned to each item, but when the test sheet is generated separately from the unique key in question, the code is partially printed in a predetermined area of the test strip to generate a new unique key of the corresponding code, The unique key of the subject, the unique key of the question, the information of the test paper, and the information of the learner are stored and retained by the mobile device 10 or the server 30.

If it is determined that the specific problem is incorrect, the unique key of the code is extracted from the code of the item area of the printed matter 40, and then transferred to the mobile device 10 or the server 30 for storage management.

The mobile device 10 or the server 30 extracts the unique key of the question related to the unique key of the corresponding code and uses it to determine what the wrong problem is and then generates a new wrong answer note, You can perform functions related to tracking, wrong answer notes.

This method is problematic because the mobile device 10 or the server 30 stores the relationship information of the code unique key and the unique key in question and prints only the code unique key in the print product 40, It is possible to change the information by only modifying the relation information between the code inherent key and the inherent key of the question, thereby alleviating the restriction of the printable article 40 which can not be corrected and also making it possible to economically manage the learning history of the learner have.

On the other hand, in the case of questionnaires composed of multiple-choice questions, the learner's grading process can be implemented without any need. The mobile device 10 can determine which answer the learner has chosen for each problem while solving the problem using the coordinate information received from the smart pen 20. [ In this case, the mobile device 10 or the server 30 stores the correct answer information for each question, and then the score is automatically compared with the answer selected by the learner, and a wrong answer note according to the score result can be generated and provided have.

The method of providing a wrong answer using a smart pen according to an embodiment of the present invention may be implemented in the form of a program command that can be executed through various computer means and recorded in a computer readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination. The program instructions recorded on the medium may be those specially designed and configured for the present invention or may be available to those skilled in the art of computer software. Examples of computer-readable media include magnetic media such as hard disks, floppy disks and magnetic tape; optical media such as CD-ROMs and DVDs; magnetic media such as floppy disks; Magneto-optical media, and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions include machine language code such as those produced by a compiler, as well as high-level language code that can be executed by a computer using an interpreter or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.

The present invention can be applied to the field of e-learning using a smart pen.
