The information code performs a function for indicating information to be encoded in a unit cell in a manner to be described later.

All other reference codes and information codes except for the cross reference code have the same geometric shape. That is, the reference codes and information codes except for the intersecting reference code have a shape of rotational symmetry with each other and are 'line segment shape'.

The cross reference code, unlike other reference codes and information codes, has a cross-shaped geometric shape.

Meanwhile, in the unit cell, virtual lines may be defined, and the virtual lines are composed of a plurality of horizontal virtual lines extending in a horizontal direction and a plurality of vertical virtual lines extending in a vertical direction. In the description of some embodiments of the present invention, a component called 'virtual line' may be actually printed on the medium 2000, but may not be printed.

Each of the plurality of horizontal virtual lines is parallel to each other and is disposed apart from each other by a predetermined distance.

In addition, each of the plurality of vertical virtual lines is parallel to each other and is disposed apart from each other by a predetermined distance.

For example, the electronic device 3000 determines whether the target medium 2000 on which the user is taking notes is the medium 2000 having a specific format for a special use, or is a part of the product provided in the form of a book or note. Whether it is medium (2000) or the like can be checked.

When the target medium 2000 is a medium 2000 that forms a part of a product provided in the form of a book or note, the electronic device 3000 is a medium 2000 in which the target medium 2000 is located on several pages of a book or note. ) can be checked. Alternatively, when the target medium 2000 has a specific format, the electronic device 3000 may identify a function to be implemented by the corresponding medium 2000 using the function information.

Based on the obtained identification information, the electronic device 3000 may display a template stored in advance for the target medium 2000 or handwritten content already written by the user for the target medium 2000 through the display. .

At this time, the pre-stored template for the target medium 2000 is meant to include text, images, shapes, symbols, etc. already printed on the target medium 2000 in addition to the code pattern, for example, When the target medium 2000 forms a part of a note, a plurality of lines may be printed on the target medium 2000 for easy writing by the user. It may be included in the template information about the target medium 2000 stored in advance. As another example, when the target medium 2000 forms a part of a notebook-like form, a specific date such as February 28, 2019 may be printed on the target medium 2000. As such, the target medium The fact that special information is printed in (2000) may also be included in the predetermined template information. As another example, when the target medium 2000 is a re-attachable paper such as a post-it note, a sticker, or the like, content displayed in consideration of connection information with another medium 2000 may be included in the predetermined template information.

Hereinafter, for convenience of explanation, an image displayed for the target medium 2000 including the aforementioned template information and the like is referred to as a medium image.

The electronic device 3000 may generate stroke data corresponding to the trajectory the user is taking notes, to be displayed through the display, based on location information and time information included in the received pen data. In order to generate the stroke data, at least one unit of pen data may be used.

When the stroke data is generated, the electronic device 3000 reproduces the trajectory written by the user on the target medium 2000 as it is in the corresponding position on the predetermined template displayed on the display as shown in FIG. 11 according to the generated stroke data. can do.

In other words, when the user's handwritten content is reproduced through the electronic device 3000, the trajectory of the user's handwritten content, the location of the user's handwritten content with respect to the target medium 2000, etc., are included in the pen data. It can be accurately reproduced based on the location information.

12 , the method for reproducing user handwriting includes the steps of acquiring pen data (S1100), acquiring information on the target medium 2000 based on the acquired pen data (S1200), and the target medium (2000). It may include displaying a corresponding medium image (S1300) and reproducing the user's handwriting on the medium image based on the obtained pen data (S1400).

The system 10 acquires pen data from the electronic pen 1000 or the server 4000 in the pen data acquisition step S1100 , and analyzes the pen data in the information acquisition step S1200 for the medium 2000 to obtain identification information , location information, function information, etc. are acquired, and a medium image corresponding to the medium 2000 being written is displayed through the electronic device 3000 in the medium image display step (S1300), and the user's handwriting is reproduced in the step (S1400). Based on the stroke data generated from the pen data, the user's handwriting may be reproduced in real time at a corresponding position on the medium image.

Accordingly, the electronic device 3000 may reproduce the user's handwriting in real time based on the pen data received from the electronic pen 1000 and display it through the electronic device 3000 . Hereinafter, for convenience of explanation, an image in which the user's handwriting is reproduced on a medium image is referred to as a reproduced image.

Since a more detailed description corresponding to each step has been previously described in detail, the description thereof will be omitted here.

Hereinafter, a case in which the medium 2000 used in the above-described system 10 can be reattached will be described in detail with reference to FIGS. 13 to 17 .

13 is a diagram illustrating a reattachable medium 5000 according to an embodiment of the present specification. Referring to FIG. 13 , system 10 may include a repositionable medium 5000 , at least a portion of which is reattachable.

Here, the reattachable medium 5000 means that at least a portion of the medium 2000 has viscosity so that it can be attached to a desired place or location by the user, and the user detaches the medium 2000 to change the attachment location. Even in this case, it may refer to the medium 2000 that can be reattached to another place or location by maintaining a certain degree of viscosity.

The reattachable medium 5000 may have various shapes. For example, referring to FIG. 13 , the reattachable medium 5000 has a rectangular shape, but the technical idea of the present specification is not limited thereto. can have

For example, a viscous material may be horizontally applied to the top of the medium rear surface 5000b. As another example, a double-sided tape may be horizontally attached to the top of the medium rear surface 5000b. At this time, the reattachable medium 5000 may be attached to any place through the upper end of the medium rear surface 5000b. However, the adhesive surface is not formed only on the upper end of the medium rear surface 5000b, and may be formed in any direction at any position on the medium rear surface 5000b, such as the lower horizontal direction or the left/right vertical direction.

Referring back to FIG. 13 , a code pattern may be formed on the medium front surface 5000a. For example, a unit cell group UCG may be printed on at least a portion of the medium front surface 5000a.

Here, the unit cell group (UCG) may mean a plurality of unit cells adjacent to each other. In this case, the coordinate values encoded in the unit cells in the unit cell group (UCG) may have the same directionality. Specifically, when unit cells in the unit cell group UCG have x and y coordinate values, the direction of increase of the x-coordinate value and the direction of increase of the y-coordinate value of each unit cell may be the same.

The code pattern may be implemented at any position on the medium front side 5000a and in any direction. For example, the code pattern may be implemented with or without a blank space from the periphery of the medium front side 5000a. For another example, the code pattern may be implemented on a portion of the medium front side 5000a except for a portion corresponding to the adhesive surface on the medium rear surface 5000b, or may be implemented on a portion overlapping a portion corresponding to the adhesive surface.

Meanwhile, although not shown in FIG. 13 , the reattachable medium 5000 may refer to the above-described reattachable medium set. For example, in general, when the reattachable medium 5000 is provided to the user, a set of reattachable mediums in which a preset number of reattachable mediums 5000 are stacked may be provided. This allows the user to electronically reproduce the user's handwriting using the re-attachable medium 5000 to which the system 10 is applied at the moment of need.

14 is a diagram illustrating a repositionable sheet 6000 according to an embodiment of the present specification. The reattachable sheet 6000 may have a unit cell group (UCG) on its front surface and an adhesive surface on its rear surface.

The repositionable sheet 6000 may be understood as a product, provision, or semi-finished product for mass production of the repositionable medium 5000 . For example, the repositionable sheet 6000 may be divided into a plurality of repositionable mediums 5000 through an additional process. In order to improve the productivity of the reattachable sheet 6000, a method in which a code pattern and an adhesive surface are provided on the reattachable sheet 6000 according to an embodiment of the present specification will be described below.

Referring to FIG. 14 , the reattachable sheet 6000 may include a first portion 6100 , a second portion 6200 , a third portion 6300 , and an adhesive portion SP. In the reattachable sheet 6000 , an adhesive material may be applied to the rear surface of the adhesive part SP, and a code pattern may be included on the front surfaces of the first part 6100 , the second part 6200 , and the third part 6300 .

The first portion 6100 may at least partially overlap with the adhesive portion SP, which will be described later. For example, one end of the first portion 6100 may overlap the adhesive portion SP, and in this case, the rear surface of the overlapping first portion 6100 may have an adhesive material applied thereto to have viscosity.

The second portion 6200 may refer to another portion that can be separated from the reattachable sheet 6000 into the reattachable medium 5000 .

The second portion 6200 may at least partially overlap the adhesive portion SP, which will be described later. For example, one end of the second part 6200 may overlap the adhesive part SP, and in this case, the rear surface of one end of the overlapping second part 6200 may be coated with an adhesive material to have viscosity.

The second portion 6200 may be adjacent to the first portion 6100 . For example, referring back to FIG. 14 , one end of the second part 6200 and one end of the first part 6100 may face each other in the x-axis direction. As another example, the first portion 6100 and the second portion 6200 may be adjacent to each other through the adhesive portion SP. Specifically, a portion of the first portion 6100 that overlaps the adhesive portion SP and a portion of the second portion 6200 that overlaps the adhesive portion SP may contact each other.

The third portion 6300 may refer to another portion that can be separated from the reattachable sheet 6000 into the reattachable medium 5000 .

The third portion 6300 may at least partially overlap with the adhesive portion SP, which will be described later. For example, one end of the third part 6300 may overlap the adhesive part SP, and in this case, a back surface of one end of the overlapping third part 6300 may be coated with an adhesive material to have viscosity.

The third portion 6300 may be adjacent to the first portion 6100 . For example, referring back to FIG. 14 , the third portion 6300 may be adjacent to the first portion 6100 in the y-axis direction. As another example, the first portion 6100 and the third portion 6300 may be adjacent to each other through the adhesive portion SP. Specifically, a portion of the first portion 6100 that overlaps the adhesive portion SP and a portion of the third portion 6300 that overlaps the adhesive portion SP may contact each other.

The adhesive portion SP may mean a portion on which an adhesive material is applied to at least a portion of the reattachable sheet 6000 . For example, the adhesive portion SP may include a band portion extending in the x-axis direction of the reattachable sheet 6000 . In this case, an adhesive material may be applied to the rear surface of the adhesive portion SP. As another example, at least a portion of the adhesive portion SP may be implemented in a band shape through which portions of the first to third portions 6100 , 6200 , and 6300 pass.

A code pattern may be implemented on the front surface of the adhesive portion SP. For example, a code pattern related to the first code pattern is implemented on the front surface of the portion overlapping the first portion 6100 of the adhesive portion SP, and a second code pattern is implemented on the front surface of the portion overlapping the second portion 6200 . Code patterns related to code patterns may be implemented. For another example, a code pattern in which icon information is encoded may be provided on the front surface of the adhesive portion SP.

On the other hand, the adhesive part SP is not necessarily implemented in a single band shape, and as shown in FIG. 14 , the adhesive part SP may include a plurality of band parts spaced apart from each other in the y-axis direction.

The first to third portions 6100 , 6200 , and 6300 may include a code pattern on one or both surfaces, respectively. For example, a first code pattern including a first unit cell group (UCG1) is printed on the entire surface of the first part 6100, and a second unit cell group (UCG2) is included on the entire surface of the second part 6200 A second code pattern may be printed, and a third code pattern including the third unit cell group UCG3 may be printed on the entire surface of the third portion 6300 .

Coordinate information or location information obtained by decoding codes encoded in the first to third unit cell groups UCG1, UCG2, UCG3 according to an embodiment of the present specification may increase or decrease in a specific direction.

As an example, referring back to FIG. 14 , the coordinates corresponding to the x-axis obtained from the first unit cell group UCG1 of the first part 6100 gradually decrease in the x-axis direction, and the coordinates corresponding to the y-axis are y may gradually decrease in the axial direction. In addition, the coordinates corresponding to the x-axis obtained from the second unit cell group UCG2 of the second part 6200 gradually increase in the x-axis direction, and the coordinates corresponding to the y-axis gradually increase in the y-axis direction. there is. In addition, the coordinates corresponding to the x-axis obtained from the third unit cell group UCG3 of the third part 6300 gradually decrease in the x-axis direction, and the coordinates corresponding to the y-axis gradually decrease in the y-axis direction. there is.

As another example, referring back to FIG. 14 , the increase direction of the coordinates corresponding to the x-axis obtained from the first unit cell group UCG1 is an increase in the coordinates corresponding to the x-axis obtained from the second unit cell group UCG2. It may be in a different (opposite) direction to the direction. In addition, the direction of increase of the coordinates corresponding to the y-axis obtained from the first unit cell group UCG1 is different (opposite) from the direction of increase of the coordinates corresponding to the y-axis obtained from the second unit cell group UCG2. can In addition, the direction of increase of the coordinates corresponding to the x-axis obtained from the third unit cell group (UCG3) is the same direction as the direction of increase of the coordinates corresponding to the x-axis obtained from the first unit cell group (UCG1), and the second unit The direction of increase of the coordinates corresponding to the x-axis obtained from the cell group UCG2 is different (opposite) from the direction of increase, and the direction of increase of the coordinates corresponding to the y-axis obtained from the third unit cell group UCG3 is the first unit cell It may be in the same direction as the direction of increase of the coordinates corresponding to the y-axis obtained from the group UCG1 and different (opposite) from the direction of increasing the coordinates corresponding to the y-axis obtained from the second unit cell group UCG2. .

Meanwhile, in order to improve the productivity of the reattachable medium 5000 , the code patterns printed on the first part 6100 and the second part 6200 may have a preset positional relationship. For example, the first code pattern printed on the first part 6100 may have the same pattern as the code pattern obtained by rotating the second code pattern printed on the second part 6200 . Specifically, the first code pattern may be a pattern in which the second code pattern is rotated by 180 degrees with respect to the adhesive portion SP. As another example, the coordinates corresponding to the y-axis obtained from the first unit cell group UCG1 spaced apart by a first distance in the y-axis direction from the adhesive part SP are opposite to the y-axis direction from the adhesive part SP. Coordinates corresponding to the y-axis obtained from the second unit cell group UCG2 spaced apart by a first distance in the direction may be the same.

In the above, the position information encoded in the unit cell group (UCG) in each part in the reattachable sheet 6000 has been mainly described, but the technical idea of the present specification is not limited thereto, and each unit cell group (UCG) is configured. The same may be applied to location information obtained by photographing a unit cell, and the same may be applied to location information obtained from a code pattern including a unit cell group (UCG) of each part.

In addition, although it has been described above that the reattachable sheet 6000 includes the first to third portions 6100 , 6200 , and 6300 for convenience of explanation, the reattachable sheet 6000 includes the first to third It goes without saying that a plurality of other parts (eg, the fourth, fifth, 6th, ??, n part, where n is a natural number) implemented in the same or similar manner as the parts 6100 , 6200 , and 6300 may be included.

For example, the adhesive portion SP on the repositionable sheet 6000 includes a first adhesive portion and a second adhesive portion spaced apart from each other in a preset direction, and the repositionable sheet 6000 is a portion of the first adhesive portion. It may include a first portion 6100 overlapping at least a portion and a fourth portion overlapping at least a portion of the second adhesive portion. Here, the fourth part is adjacent to the second part 6200 in the y-axis direction and may include a code pattern similar to the first code pattern implemented in the first part 6100 .

15 is a view showing a sheet stack in which reattachable sheets 6000 are stacked according to an embodiment of the present specification.

A sheet stack may be understood as a product, provision or semi-finished product for mass production of the repositionable medium 5000 . For example, the sheet stack may be divided into multiple repositionable mediums 5000 through further processing.

Referring to FIG. 15 , the sheet stack may include n repositionable sheets 6000 . For example, the sheet stack may be implemented in which first to n (n is a natural number) reattachable sheets 6000-1, ??, 6000-n are vertically stacked. Specifically, the sheet stack may be formed by pressing the first to n-th repositionable sheets.

Each of the repositionable sheets 6000 may correspond to each other in a vertical direction. For example, first portion 6100-1 of first repositionable sheet 6000 - 1 may have a similar code pattern as first portion 6100 - 2 of second repositionable sheet 6000 - 2 can have Specifically, the coordinates corresponding to the x-axis and the coordinates corresponding to the y-axis obtained in the two parts 6100-1 and 6100-2 described above may have the same increasing direction.

It may include printing (S2300), stacking and pressing the repositionable sheet 6000 (S2400), and cutting the stacked sheet stack to a preset size (S2500).

Hereinafter, each step will be described in detail.

In order to manufacture the reattachable medium 5000, the roll paper may be cut in sheet units (S2100). Here, the roll paper may be understood as winding the paper used for manufacturing the reattachable sheet 6000 for ease and convenience of storage. Also, here, the sheet may be set to a size for manufacturing the reattachable sheet 6000 described above.

In order to manufacture the reattachable medium 5000, an adhesive material may be applied along one axis (S2200). Here, the uniaxial may mean a virtual line on which the adhesive material is applied. For example, the single axis may mean an axis parallel or perpendicular to a direction in which the roll paper is unrolled. As another example, the uniaxial may refer to the aforementioned x-axis or y-axis. The step of applying the adhesive material (S2200) may be performed prior to the step of cutting the roll paper (S2100).

In order to manufacture the reattachable medium 5000, a code pattern may be printed on the entire surface of the sheet (S2300). The code pattern may be printed on the sheet in the manner described elsewhere herein. For example, in the step of applying the adhesive material ( S2200 ), the adhesive material may be applied to the back surface of the adhesive part SP, and the first code pattern and the second code pattern may be printed in consideration of the adhesive part SP. can

A cut mark may be printed along with the code pattern and identify the repositionable medium 5000 within the repositionable sheet 6000 . For example, the cutting mark may distinguish the first part 6100 and the second part 6200 .

As a method of printing the code pattern, master printing, offset printing, UV printing, digital printing or laser printing may be used.

The code pattern printing step (S2300) may be performed prior to the adhesive material application step (S2200) or the roll paper cutting step (S2100).

In order to manufacture the reattachable medium 5000, sheets may be laminated and compressed (S2400). The repositionable sheets 6000 may be laminated and compressed in this step to form a sheet stack.

To make the repositionable medium 5000, the stacked sheet stack may be cut to a preset size. For example, the reattachable medium 5000 may be created by cutting the sheet stack to a size corresponding to the first portion 6100 or the second portion 6200 .

Meanwhile, in the above-described method for manufacturing a reattachable medium, at least one of the constituent steps may be omitted, the order of the steps may be changed, or at least some of the constituent steps may be performed by another entity. For example, the method for manufacturing a repositionable medium includes preparing a sheet including an adhesive portion coated with an adhesive material along one axis on the back side and printing a code pattern (S2300), and cutting the above-described roll paper. (S2100), the step of applying the adhesive material (S2200), the step of laminating and pressing the sheet (S2400), and the step of cutting the stacked sheet (S2500) may be omitted.

Hereinafter, a method of connecting a plurality of different mediums will be described with reference to FIGS. 18 to 24 .

18 is a diagram illustrating that different mediums are connected to each other according to an embodiment of the present specification.

Different mediums may be interconnected when a connection condition is satisfied. Connection of different mediums may mean processing data in consideration of whether the mediums are connected to each other on the electronic device 3000 . In other words, it may mean that different mediums are electronically connected through the electronic device 3000 .

For example, referring to FIG. 18 , the first content is recorded in the first medium 2000-1 and the second content is recorded in the second medium 2000-2, and the first content and the second content are mutually In a related case, the electronic device 3000 may process the first reproduced image for the first content and the second reproduced image for the second content as connected. Specifically, when attaching the reattachable second medium 2000-2 to the first medium 2000-1 and writing interrelated contents, the electronic device 3000 sets the first medium 2000-1 to the first medium 2000-1. The first reproduced image and the second reproduced image for the second medium 2000 - 2 may be output together.

The system 10 may determine whether a connection condition is satisfied in order to connect different mediums. For example, the electronic device 3000 may determine whether a connection condition between different media is satisfied based on pen data obtained from the electronic pen 1000 .

Hereinafter, connection conditions for the system 10 to connect different mediums will be described in detail.

19 and 20 are diagrams illustrating connection conditions for connecting different mediums according to an embodiment of the present specification.

The connection condition may be set based on pen data acquired within a preset time period.

The preset time period may be set sufficiently short or long. For example, the preset time period may be set within 0.1 seconds to 10 seconds. For another example, the preset time interval may be set to 10 seconds or longer or set to infinity.

For example, referring to FIG. 19 , the system 10 acquires the second pen data for the second medium 2000-2 at a first time point within a preset time period, and after the first time point within a preset time period When the first pen data for the first medium 2000-1 is acquired at the second time point, and a change amount of the pressure information equal to or greater than the preset value is detected at the third time point between the first time point and the second time point, the first medium ( 2000-1) and the second medium 2000-2 may determine that the connection condition is satisfied. In this case, the first pen data may include first identification information indicating the first medium 2000-1, and the second pen data may include second identification information indicating the second medium 2000-2. can In other words, the electronic device 3000 sets a condition in which the first identification information at the first time point and the second identification information at the second time point indicate different mediums and a preset value for the amount of change in the pressure information at the third time point. In the case of more than one, it can be determined that the connection condition is satisfied. In this case, the user draws a line from the second medium 2000-2 to the first medium 2000-1 using the electronic pen 1000 to draw the first medium 2000-1 and the second medium 2000 -2) can be connected electronically.

As another example, the system 10 may include first identification information and first pressure information acquired at a first time point within a preset time, second identification information acquired at a second time point after the first time point within a preset time, and second Based on the pressure information, it is possible to determine whether a connection condition is established. Specifically, in the electronic device 3000 , pen down and pen up operations are performed at a first time point, pen down and pen up operations are performed at a second time point, and first identification information and If the medium indicated by the second identification information is different, it may be determined that the connection condition is satisfied. Here, the pen-down operation may mean a case in which the pressure information abruptly increases from '0' to a specific value, and the pen-up operation may mean a case where the pressure information suddenly becomes '0' from a specific value. In this case, the user sequentially taps the first medium 2000-1 and the second medium 2000-2 within a preset time to tap the first medium 2000-1 and the second medium ( 2000-2) can be connected electronically. Further, similar to the tapping method, the user may electronically connect different mediums through a double tap action.

The system 10 may determine whether the connection condition is satisfied through image analysis. For example, referring to FIG. 20 , the system 10 obtains images obtained by photographing the first medium 2000-1 and the second medium 2000-2 from the image sensor, and analyzes the obtained images to obtain It may be determined whether the first medium 2000 - 1 and the second medium 2000 - 2 are connected. Specifically, the electronic device 3000 may determine that the connection condition is satisfied when images for different mediums are included in the acquired image. In this case, when images of different mediums include different code patterns or at least a part of the code patterns are covered, the electronic device 3000 may determine that images of different mediums are included in the images. Here, the image sensor may be provided in the electronic pen 1000 or the electronic device 3000 or a separate image sensor may be used.

The system 10 may determine whether a connection condition is satisfied using the icon information. For example, a user taps a portion on which an icon is printed among the first medium 2000-1 using the electronic pen 1000 or writes on a portion on which an icon is printed, and then writes a note on the portion on which an icon is printed, and the second medium 2000-2 When taking notes or tapping the second medium 2000 - 2 , the first medium 2000 - 1 and the second medium 2000 - 2 may be electronically connected. In this case, the electronic device 3000 obtains icon information from the first pen data for the first medium 2000-1, and obtains the second pen data for the second medium 2000-2 to obtain the first medium It may be determined whether the connection conditions of the 2000 - 1 and the second medium 2000 - 2 are satisfied.

21 is a diagram illustrating a method of connecting different mediums using a question message according to an embodiment of the present specification.

Hereinafter, each step will be described in detail.

The electronic device 3000 may acquire first pen data for the first medium 2000 - 1 from the electronic pen 1000 at a first time ( S3100 ). Here, the first pen data for the first medium 2000 - 1 may include first identification information indicating the first medium 2000 - 1 .

The electronic device 3000 may acquire second pen data for the second medium 2000 - 2 from the electronic pen 1000 at a second time ( S3200 ). Here, the second pen data for the second medium 2000 - 2 may include second identification information indicating the second medium 2000 - 2 .

The electronic device 3000 may output a message asking whether to connect (S3300).

Before outputting the question message, the electronic device 3000 may determine whether a connection condition is satisfied based on the first pen data and the second pen data. For example, the electronic device 3000 may output a question message when the above-described connection condition is satisfied. For another example, the electronic device 3000 may output a question message when the first identification information and the second identification information included in the first pen data and the second pen data respectively indicate different media. In this case, the first pen data and the second pen data may be acquired within a preset time.

Here, the question message may include a message asking whether to connect the first medium 2000-1 and the second medium 2000-2 to each other. The question message may be provided to the user visually or audibly through the electronic device 3000 . The question message may be output before reproducing the user's handwriting in the electronic device 3000 or may be output after reproducing the user's handwriting.

The electronic device 3000 may receive a user response to the question message (S3400). The electronic device 3000 may receive a user response through the input module 3100 . Here, the user response may include a 'yes' or 'no' response to the question message.

Meanwhile, the step of outputting the question message ( S3300 ) and the step of receiving the user response ( S3400 ) may be omitted. For example, when the above-described connection condition is satisfied between the first medium 2000-1 and the second medium 2000-2, the electronic device 3000 does not output a question message and outputs an image as described below. can do. For another example, when the electronic device 3000 obtains a user input for deactivating a function to check whether a connection is made through a question message when connecting different mediums from a user, outputting a question message (S3300) and a user response The step of receiving ( S3400 ) may be omitted. As another example, the electronic device 3000 may display the user response obtained by performing the step of outputting the question message (S3300) and the step of receiving the user response (S3400) as it is later when the connection condition is satisfied between different mediums. can be applied Specifically, in the first time interval, the connection condition is satisfied between the first medium 2000-1 and the second medium 2000-2, and the electronic device 3000 receives a user response indicating connection to the question message. In one case, when the connection condition between the third medium and the fourth medium is satisfied in the second time interval after the first time interval, the electronic device 3000 generates connection data without outputting a question message, or the third medium and the third medium 4 You can print an image about medium.

For example, the user input may include an input for starting an application installed or stored in the electronic device 3000 implementing the system 10 . As another example, the user input may include an input for starting an application implementing the system 10 and an input for selecting at least one of the first medium 2000-1 and the second medium 2000-2 in the application. can

Meanwhile, the step of receiving the user input ( S3500 ) may be omitted. In this case, when receiving a user response to the question message, the electronic device 3000 may output a reproduced image as will be described later. In other words, when different mediums are connected by a user, the electronic device 3000 may immediately output a related image or may receive and output a user input later.

Alternatively, the step of receiving the user input (S3500) is performed prior to the steps (S3100, S3200) of acquiring pen data for the medium 2000 from the electronic pen 1000 or the step of outputting a question message (S3300). may be performed.

The electronic device 3000 may output the first reproduced image and the second reproduced image (S3600). Here, the first reproduced image may mean an image in which the user's handwriting on the first medium 2000-1 is reproduced, and the second reproduced image is the user's handwritten note on the second medium 2000-2. One content may mean a reproduced image.

When outputting the image, the electronic device 3000 may display the first reproduced image and the second reproduced image together through the output module 3200 .

Specifically, the electronic device 3000 may output at least a portion of the first reproduced image and at least a portion of the second reproduced image in an overlapping state.

The positional relationship between the first reproduced image and the second reproduced image may correspond to the positional relationship between the first medium 2000-1 and the second medium 2000-2. Referring back to FIG. 18 , when the user attaches the second medium 2000-2 on the first medium 2000-1 and takes notes, the electronic device 3000 displays the second reproduced image on the first reproduced image. can be displayed To this end, the electronic device 3000 receives the first medium 2000-1 and the second pen data from the first pen data for the first medium 2000-1 and the second pen data for the second medium 2000-2. Information on the positional relationship of the medium 2000 - 2 may be acquired and used to display a reproduced image.

When the first reproduced image and the second reproduced image are displayed overlapping each other, at least one of the first reproduced image and the second reproduced image may be displayed transparently. For example, when the second reproduced image is displayed on the first reproduced image, at least a part of the second reproduced image may be displayed transparently in order to increase the visibility of the first reproduced image superimposed by the second reproduced image.

Meanwhile, the first reproduced image and the second reproduced image may be output regardless of the positional relationship between the first medium 2000 - 1 and the second medium 2000 - 2 . For example, the first reproduced image and the second reproduced image may be displayed in parallel, or at least one of the first reproduced image and the second reproduced image may be reduced and displayed.

Alternatively, the reproduced image may be output based on priority. For example, first pen data for the first medium 2000-1 is acquired at a first time point, and the second pen data for the second medium 2000-2 is obtained at a second time point that is later than the first time point. When data is obtained, the first reproduced image may have a higher priority than the second reproduced image. As another example, when pen-down is performed between a first time point at which the first pen data is acquired and a second time point at which the second pen data is acquired, the first reproduced image may have a higher priority than the second reproduced image. can Furthermore, the electronic device 3000 may display a reproduced image having a higher priority on or first display a reproduced image having a lower priority.

Alternatively, the arrangement of the first reproduced image and the second reproduced image may be selected by the user.

For example, the electronic device 3000 may generate connection data when the first pen data and the second pen data are acquired within a preset time. As another example, the electronic device 3000 may generate connection data when the above-described connection condition is satisfied.

The connection data may refer to data indicating that different mediums are connected. For example, when the first medium 2000-1 and the second medium 2000-2 are connected, the electronic device 3000 performs the connection of the first medium 2000-1 and the second medium 2000-2. The indicated connection data may be stored in the memory module 3400 .

The electronic device 3000 may output an image based on the connection data (S4400). For example, when the electronic device 3000 outputs a reproduced image for the medium 2000 that satisfies the connection condition, it loads the connection data and displays an image of another medium connected to the above-described medium 2000 together with the reproduced image. can be printed out.

On the other hand, the implementation of a specific function may be implemented by the medium 2000 or the reattachable medium 5000 itself as described above, but includes the operation of connecting different mediums described in other parts of this specification. it might be For example, when specific content is written on the first medium 2000-1 and the second medium 2000-2 can implement a specific function, the first medium 2000-1 and the second medium 2000 When -2) are connected to each other, a specific function of the second medium 2000-2 may be performed with respect to specific content described in the first medium 2000-1. Specifically, when the reattachable medium 5000 having a security function is attached to or connected to the medium 2000 having a specific content, a security function may be performed for the specific content.

The system 10 may perform various functions other than the above-described functions by using the reattachable medium 5000 . For example, the electronic device 3000 may reproduce the handwritten content based on the position where the reattachable medium 5000 is attached or the place where it is written. Specifically, the electronic device 3000 obtains, from the electronic pen 1000, place information on the location where the reattachable medium 5000 is attached or the written location, and displays thumbnails, etc. according to the location information on the map through the display. It is possible to display the mark of and to output the handwritten contents when touched.

Here, the electronic pen 1000 or the electronic device 3000 may include a location tracking module in order to obtain information on a location where the medium 2000 is attached or a written location. For example, the electronic pen 1000 includes a GPS module, and when a user takes notes on the medium 2000 using the electronic pen 1000 , the GPS module may acquire place information.

Meanwhile, the above-described functions may be implemented together in the process of reproducing the handwritten content according to the location. For example, the electronic device 3000 may reproduce the handwritten content based on the place information or provide the handwritten content based on the place information or an image in which the handwritten content is reproduced to another electronic device through an email or other application. In addition, the above description may be equally applied not only to the reattachable medium 5000 but also to the general medium 2000 .

In addition, the contents written on the reattachable medium 5000 in the system 10 may be associated and stored. For example, when the user takes notes on the at least one reattachable medium 5000 at different first, second, and third viewpoints, the electronic device 3000 may provide a first reproduced image of the handwritten content. , the second reproduced image and the third reproduced image may be stored or output together. For another example, in the electronic device 3000 , after the user writes on the first reattachable medium 5000 - 1 at a first time and writes on the second reattachable medium 5000 - 2 at a second time, When the first reattachable medium 5000 - 1 and the second reattachable medium 5000 - 2 are connected, images or information about handwritten contents may be stored or output together.

Here, the content written on the reattachable medium 5000 may be classified and processed as specific information using optical character recognition (OCR) or the like. For example, the electronic device 3000 obtains and categorizes person information such as a phone number, date of birth, name, etc. using pen data obtained at different points in time, and stores the classified person information in association with each other or through a display. can be printed out.

The system 10 may use different medium 2000 connection methods described in other parts of this specification together in implementing the above-described functions. For example, when the different mediums 2000 each include code patterns for implementing different functions, when the different mediums 2000 are connected using the electronic pen 1000, the electronic device 3000 is Different functions can be implemented complexly. Specifically, the electronic pen 1000 obtains first pen data including the first function information from the first medium 2000-1, and obtains the first pen data including the first function information from the second medium 2000-2. 2 Acquire pen data, and the electronic device 3000 obtains the first pen data and the second pen data to determine whether the first medium 2000-1 and the second medium 2000-2 satisfy the connection condition , and when the first medium 2000-1 and the second medium 2000-2 are connected, the electronic device 3000 provides the first pen data, the second pen data, the first function information, and the second function information. Based on the reproduced image, functions corresponding to the first function information and the second function information may be sequentially implemented. More specifically, when the user connects the first medium 2000-1 having a notification function and the second medium 2000-2 having a special effect function, the electronic device 3000 displays the handwritten content based on the notification information After the notification time based on , it is possible to provide notification contents with special effects added.

Here, the first function information and the second function information may include at least one of the aforementioned security function, notification function, mailing function, special effect function, and question-and-answer function.

The present invention described above is capable of various substitutions, modifications and changes within the scope without departing from the technical spirit of the present invention for those of ordinary skill in the art to which the present invention pertains. It is not limited by the drawings. In addition, the embodiments described in this document may not be limitedly applied, but all or part of each embodiment may be selectively combined so that various modifications may be made. Furthermore, steps constituting each embodiment may be used individually or in combination with steps constituting other embodiments.
