A device that recognizes coordinate values or pattern IDs. Here, for example, a digital paper and a digital pen, when a user writes a handwriting or drawing on a digital paper with a digital pen, the digital pen recognizes X and Y coordinate values corresponding to the handwriting or drawing on the digital paper. In some embodiments, the handwriting or picture written by the user on the digital paper is displayed on the external device by transmitting the same to the external device such as a personal computer, and when the digital pen recognizes the pattern ID displayed on the digital paper and transmits it to the external device, There is an embodiment in which the device provides information corresponding to the pattern ID.

A keyboard emulator is a device or program that emulates the functionality of a keyboard (or keypad) by emulating it in another kind of hardware or software.

The keyboard-only area refers to a specific area set as a keyboard-only area among areas of the digital paper.

The keyboard area X and Y coordinates mean X and Y coordinate values determined in the unit cell pattern located in the keyboard dedicated area.

The keyboard-only pattern is a pattern in which the sign of data displayed in the first cell is displayed differently from the conventional method. For example, the display is longer or shorter than the length of the sign of the previously displayed data, or is displayed at a position or shape different from the sign of the previously displayed data.

The keyboard-only code means a code of data displayed in a manner different from that of data displayed in a conventional manner in the first cell.

The keyboard dedicated unit cell pattern is formed by a predetermined number of first cells marked with a keyboard dedicated code.

The keyboard-only X and Y coordinates are coordinates of the keyboard-specific unit cell pattern determined by a combination of data corresponding to the keyboard-only code.

The keyboard-specific pattern ID means a pattern ID specialized for each key of the keyboard displayed on the digital paper for the keyboard emulator.

The digital paper for the keyboard emulator is a digital paper used in the keyboard emulator according to the preferred embodiment of the present invention, and any one of a keyboard-only area, a keyboard-only pattern, and a keyboard-only pattern ID is printed on the article of manufacture.

The digital pen combined with the keyboard emulator is a digital pen that recognizes any one of the keyboard area X, Y coordinate value, keyboard dedicated X, Y coordinate value, and keyboard dedicated pattern ID in the paper for keyboard emulator according to the preferred embodiment of the present invention. It also recognizes the coordinate value or pattern ID of the digital paper other than the digital paper for the emulator and transmits it to an external device so that the external device can display the handwriting or picture of the user or provide information corresponding to the pattern ID.

A detailed description of the digital paper 200 is as follows.

FIG. 2A is a diagram exemplarily showing a portion of digital paper displaying a position indication pattern on a surface; FIG.

As shown in FIG. 2A, the position display pattern formed on the surface of the digital paper 200 has binary data encoded in a manner distinguished from the first cell 201 and the first cell 201 where binary data is encoded. The second cell 202, the first cell 201, and the second cell 202, which are displayed and have no data, are configured to include a unit cell pattern 210 formed by a predetermined number or more.

As shown in FIG. 2A, in each of the first cells 201, x and y, which are binary data information for giving the X and Y coordinate values of the unit cell pattern 210, are (0,0), ( 0,1), (1,0), or (1,1) or the like.

Meanwhile, the present embodiment has been described based on binary data as coded and displayed data in each of the first cell 201 and the second cell 202, but the present invention is not limited thereto. Data represented by = 0 or 1, y = 0 or 1) or more decimal digits ((進 數), ie ternary numbers (x = 0 or 1 or 2, y = 0 or 1 or 2), hexadecimal data ( x = 0 or 1 or 2 or 3, y = 0 or 1 or 2 or 3) and the like.

As shown in Fig. 2A, the unit cell pattern 210 consists of a collection of NxM (4x4) cells 201 and 202, which are read at a time by a digital pen to be described later as a sensing means. Independently identifiable size, also called a window (window). Among the 4x4 cells 201 and 202 constituting the unit cell pattern 210, one cell 201 is 13 and the second cell 202 is 3. In the present embodiment, for convenience of description, the size of the unit cell pattern 210 is limited to 4 × 4, but the present invention is not limited thereto, and the number of N and M may be within the range of natural numbers. Although the number is the same, the present invention is not limited thereto, and the number of N and M may be different. That is, N and M are natural numbers, and N = M or N ≠ M.

In FIG. 2A, a combination of binary data corresponding to thirteen first cells 201 indicates a coordinate value (or window value) of a corresponding unit cell pattern. Meanwhile, the three second cells 202 are located at a specific position in the unit cell pattern 210, that is, at a lower right corner, and a line segment connecting the second cells 202 has a specific shape, that is, a shape of ''. To achieve. In this way, a collection of three second cells 202 provided in a specific position and a specific shape in the unit cell pattern 210 is referred to as a direction flag 203. The specific position of the direction key 203 allows the unit cell pattern 210 to be separated from other unit cell patterns adjacent to each other independently, and the specific form distinguishes the direction of the digital paper 200 and thus the digital paper 200. ) Is to know the degree of rotation. This will be described later in more detail. In the present embodiment, the direction key 203 has a shape of '', but the present invention is not limited thereto, and the direction key 203 may be variously configured in the form of '┐' or '⊥' which can know the rotation state of the digital paper 200. There will be.

Next, examples of the method of providing the X coordinate value and the Y coordinate value of the unit cell pattern will be described in more detail with reference to FIGS. 2B to 2I.

<Method of giving X coordinate value of unit cell pattern in position display pattern>

FIG. 2B illustrates an example of the unit cell patterns 210 of the same row in the position display pattern. As shown in FIG. 2A, each cell of the present invention has an X coordinate and a Y coordinate of the unit cell pattern 210. Although x and y which are data information are contained simultaneously, it is a figure for demonstrating separately the data part about X coordinate among them.

As shown in FIG. 2B, the X coordinate value (or binary window value) of the unit cell pattern 210 sequentially increases by 1, such as 0000000000000 → 0000000000001 → 0000000000010 → 0000000000011, toward the unit cell pattern in the right direction. The X coordinate value (or binary window value) reads binary data corresponding to the thirteen first cells 201 in the unit cell pattern 210 in the order of 1 to 13 times as shown in FIG. Combination to go to. As such, when the X coordinate value (or binary window value) of the unit cell pattern 210 is sequentially increased by 1 toward the unit cell pattern in the right direction, the coordinate window is precisely matched with the actual window by the regularity. Even if they do not match, you will be able to restore the actual window values. The coordinate window refers to a collection of N × M size cells read by a digital pen, which will be described later. However, it should be noted that the image observed by the digital pen to be described later may be larger than the coordinate window.

Next, the unit cell patterns 210 of the same row arranged as shown in FIG. 2B are repeatedly arranged in the Y direction (up and down directions) as shown in FIG. 2D to form a plurality of rows.

FIG. 2E is another embodiment of FIG. 2B, and as shown in FIG. 2E, the X coordinate value (or binary window value) does not necessarily have to start from zero and may start with any value. At this time, the digital pen that reads it knows this, and when it wants to know the relative X coordinate value (or binary window value) from the starting point, it calculates an arbitrary value by subtracting from the currently read X coordinate value (or binary window value). do. If all X coordinate values (or binary window values) reach the maximum value that can be displayed, the next X coordinate value (or binary window values) can be set to zero.

<How to give Y coordinate value of unit cell pattern in position display pattern>

FIG. 2F illustrates an example of unit cell patterns 210 in the same column in the position display pattern. As shown in FIG. 2A, each cell includes x, which is data information about the X and Y coordinates of the unit cell pattern 210. , and y are included at the same time, but only the data portion of the Y coordinate is separated from the diagram.

As shown in FIG. 2F, the Y coordinate value (or binary window value) of the unit cell pattern 210 sequentially increases by 1, such as 0000000000000 → 0000000000001 → 0000000000010 → 0000000000011 as the unit cell pattern moves downward. The Y coordinate value (or binary window value) reads binary data corresponding to the thirteen first cells 201 in the unit cell pattern 210 in the order of 1-13 times as shown in FIG. Combination to go to. As such, when the Y coordinate value (or binary window value) of the unit cell pattern 210 is sequentially increased by 1 as the unit cell pattern moves downward, the coordinate window is precisely aligned with the actual window by the regularity. Even if they do not match, you will be able to restore the actual window values.

For reference, FIG. 2C illustrates a sequence of reading data about X coordinates among data entered into each cell, and FIG. 2G illustrates a sequence of reading Y coordinate values among data entered into each cell, but is not limited thereto. For example, FIG. Alternatively, any one of the sequences of FIG. 2G may be commonly applied to the X and Y coordinates, or FIG. 2C may be applied to the Y coordinate and FIG. 2G may be applied to the X coordinate. In addition, although not shown in the drawing, the position of each cell in the same unit cell pattern (in a window) may be determined such that the number of digits of binary data increases as the spiral rotates from the center.

Next, the unit cell patterns 210 of the same column arranged as shown in FIG. 2F are repeatedly arranged in the horizontal direction to form a plurality of columns as shown in FIG. 2H.

FIG. 2I is another embodiment of FIG. 2F, and as shown in FIG. 2I, the Y coordinate value (or binary window value) does not necessarily have to start from zero and may start with any value. At this time, the digital pen that reads it knows this, and when it wants to know the relative Y coordinate value (or binary window value) from the starting point, it calculates an arbitrary value by subtracting from the currently read Y coordinate value (or binary window value). do. If all Y coordinate values (or binary window values) reach the maximum value that can be displayed, the next window value can be set to zero.

As described above, each cell constituting the position display pattern is given x (x = 0 or 1), which is data for giving the X coordinate value of the unit cell pattern 210 as shown in FIG. 2D, and the unit cell as shown in FIG. 2H. After giving y (y = 0 or 1), which is data for giving the Y coordinate value of the pattern 210, the X coordinate values of FIG. 2D and the Y coordinate values of FIG. 2H are combined with each other so that the cells at the same positions correspond to each other. 2J, the position display pattern according to the present invention is constructed. Here, the X and Y coordinate values are given in the unit cell pattern 210.

Comparing the position display pattern of FIG. 2A and the position display pattern of FIG. 2J, it can be seen that binary data values assigned to corresponding cells are slightly different. Such a difference will be described with reference to FIGS. 2C and 2G. As described above, the method may vary according to a method of granting / combining binary data corresponding to the first cell 201 in the unit cell pattern 210. That is, the position display pattern of FIG. 2A illustrates an example in which the binary data assignment / combination order of FIG. 2G is commonly applied to the X and Y coordinates, and the position display pattern of FIG. 2J illustrates the X coordinate of the binary data assignment / combination sequence of FIG. 2C. Figure 2g shows an example of applying the binary data assignment / combination sequence of Figure 2g to the Y coordinate. In any case, however, the coordinate values of the unit cell patterns corresponding to each other in the position display patterns of FIGS. 2A and 2J are the same.

Next, the direction key 203 of FIG. 2A will be described in more detail.

The arrangement of the second cell 202 constituting the directional key 203 should be arranged such that the directional key itself has a directional feature. In order to be directional, it must consist of three or more second cells 202. In the following case, the direction key has two or more directions no matter how the second cell 202 is disposed. However, when the direction key 203 is not used for rotation detection but only for error correction, two or more cells may be used. On the other hand, if the direction key 203 is simply used to distinguish adjacent unit cell patterns from each other, the direction key may be composed of only one second cell 202.

When the direction key 203 is not used for error correction but only for rotation detection, the second cell 202 does not contain any information or the second cell 202 is configured as the first cell 201. It should be understood that the configuration of the direction key 203 includes information displayed by being encoded in a manner distinguished from the.

When using the direction key 203 only for rotation detection, it is sufficient to use only three second cells 202 which do not contain any information, so that the line segments connecting the three cells have a form of ''. It is preferable to.

Some non-directional arrangements (or useless centers without center points) are such arrangements, as the three cells form an array of straight lines such as '-', '/' and '＼' as shown in FIG. 2K. Should be excluded.

A second cell that can be considered on the coordinate window in order to find an angle (90 degrees, 180 degrees, 270 degrees) in which the surface on which the position display pattern is printed is rotated when using the direction key 203 of the form '' '. The distribution form of 202 can be divided into three cases, such as (a), (b) and (c) of FIG. 2L. That is, when all cells are attached as shown in (a) of FIG. 2l on the coordination window, and are divided into two groups as shown in (b) of FIG. 2l, they are divided into three groups as shown in (c) of FIG. 2l. The case is that.

In any case of (a), (b), or (c) of FIG. 2L, if a cell (c), which is the center point, is first found and other cells that are centered around the cell (c) are recognized as being located opposite the center point, the rotation is performed. The direction key of the shape is restored.

Then, when the shape of the restored direction key is '┗', it is rotated 90 degrees clockwise, '┏' is rotated 180 degrees, and '┓' is rotated 90 degrees counterclockwise. For example, it can be seen that the direction keys of (a) of Figure 2l is not rotated, the direction keys of (b) of Figure 2l is rotated 90 degrees clockwise in the form of '┗' when restored, Figure 2l If you restore the direction key of (c), you can see that it is flipped 180 degrees in the form of '┏'. Since the rotation angle of the digital paper 200 can be known using this property, it is possible to eventually rotate the matrix of cells on the coordinate window.

Next, error correction of the position display pattern will be described.

In order to correct an error, two-bit binary data is encoded and displayed in a different manner from the first cell 201 in the second cell 202 of the direction key 203 for distinguishing the window. These two bits are used as error correction codes of the X and Y coordinate values of the unit cell pattern 210, respectively. Since the error correction code for the X coordinate value of the unit cell pattern 210 and the error correction code for the Y coordinate value of the unit cell pattern 210 operate independently, only the X coordinate of the unit cell pattern 210 is described. Since the same method as the X coordinate of the unit cell pattern 210 is applied to the Y coordinate of the unit cell pattern 210, the description thereof will be omitted.

One 4x4 window includes 13 bits, which is information of the X coordinate value of the unit cell pattern 210, but at least 4 bits should be an extra bit for 2 bit error correction. The RS (Reed-Solomon) code, which is an optimal algorithm of the block code, has a code form of (2 ^K -1, 2 ^K -1-k), that is, 2 ^K -1-k The data of bits can be reconstructed into 2 ^K -1 bits of code word, and errors of up to 2 bits can be corrected, where k is the number of codes for error correction. Twelve of the cells are used as data and four cells are used as error correction codes, so for this purpose, the number of second cells 202 constituting the direction key should be increased by one more to four. Only 11 cells of one cell 201 are subjected to error correction, and the other layer performs error processing in the upper layer.

A method for correcting the remaining bits except the upper 1 bit is as follows.

First, the number of second cells 202 constituting the direction key 203 is reconfigured to be four. Each second cell 202 is encoded using a representation different from that of the first cell 201 so as to include two bits of information. Even if the number of the second cells 202 is four, the method of calculating the X and Y coordinate values of the unit cell pattern 210 is the same as before. The only difference is that the number of first cells 201 is reduced by one in the window. Next, using RS coding, which is one of error correction codes, an error correction code for all or part of information in a data cell is calculated (encoded) and encoded by the direction key 203 for display. If the window being read is read out of the window instead of reading correctly, the error correction code will not function properly. However, the error can be corrected by performing RS decoding after calculating the position according to the original position calculation method. This may not be recoverable correctly because it is RS decoding for the estimated code word rather than the original RS encoded code word.

The method of limitedly correcting the error of the lower bit is as follows.

Since the high digits of the binary data forming the window are not much changed compared to the low digits, if the error correction is performed only for the low bit digits that change a lot, the number of the second cells 202 constituting the direction key 203 is determined. Can be reduced. By doing so, it is possible to implement more different unit cell patterns (windows). Since the number of cells constituting the direction key 203 is reduced, the probability of not seeing three cells at once is lower than the probability of not seeing four cells at once, thereby increasing the chance that the error correction function is properly realized.

Although a method of using RS coding in correcting an error of a position display pattern has been described above, the present invention is not limited thereto.

Next, the sign of the binary data displayed in the 1st cell 201 and the 2nd cell 202 is demonstrated.

On the other hand, the method as shown in Figure 2n is an example and can be matched to the meaning value and x, y differently, of course. Here, x is data entered into the first cell 201 to give the unit cell pattern 210 an X coordinate value, and y is a first cell (for giving the Y coordinate value to the unit cell pattern 210). 201) means the data entered.

Referring to FIG. 2N, since the first line segment of FIG. 2O (a) has a meaning value of 0, corresponding data is (1,1), and the second line segment of FIG. 2O (b) corresponds to a semantic value of 1. The data to be represented is (0,1), and the third line segment of FIG. 2O (c) has a meaning value of 2, indicating that the corresponding data is (1,0), and the fourth line segment of FIG. 2O (d) means Since the value is 3, the corresponding data represents (0, 0).

In addition, as another example of the sign of the binary data displayed in the second cell 202, the line segments in the same manner as the first to fourth line segments of the first cell shown in FIGS. 2M (a)-(d) may be used. The lengths of the first cells may be distinguished from line segments of the first cell.

In addition, as another example of the sign of the binary data displayed in the second cell 202, as shown in Figure 2p, starting with the intersection of the virtual X and Y axis line passing through the center point of each cell (a) One of the first segment in the first quadrant, (b) the second segment in the second quadrant, (c) the third segment in the third quadrant, and (d) the fourth segment in the fourth quadrant. Each data corresponding to each line segment may be represented by (0,0), (0,1), (1,0), (1,1), and the like.

FIG. 2Q is another example of the sign of the binary data displayed in the second cell 202. As shown in the figure, the virtual X and Y axis lines passing through the center point of each cell as shown in FIG. A first line segment that spans the positive X and Y axes around the intersection point, and (b) spans the negative X and Y axis around the intersection of the virtual X and Y axis lines that intersect each other A second line segment that is intersected with each other as shown in (c), a third line segment that spans the negative X and Y axes about the intersection of the virtual X and Y axis lines that intersect each other, and (d) One of the fourth line segments spanning the positive X axis and the negative Y axis about the intersection of the X and Y axis lines, each data corresponding to each of these line segments (0,0) , (0,1), (1,0), (1,1), and the like.

As a means for encoding binary data displayed in the first or second cell 202, various types of line segments have been described above. Each line segment may be represented by a line having a predetermined length, but a plurality of points forming the same straight line. It can be expressed as. At this time, the maximum spacing between points in one cell segment and the other points in the adjacent cell should always be shorter to avoid forming a line segment between points in the cell and points in adjacent cells. do.

In addition, the data encoded and displayed in each cell has been described based on binary data. However, the present invention is not limited thereto, and data represented by binary data or more decimal numbers, that is, hexadecimal and quaternary data, may be used depending on the number of branches. There will be.

After completing the detailed description of the digital paper 200, a system for implementing a keyboard emulator using a digital paper and a digital pen according to the first embodiment of the present invention will be described.

In order to clarify the distinction between the keyboard emulator digital paper 310 and the digital paper 200 which will be described later, the digital paper 200 is changed to the general digital paper 200 from the following description.

3A is a schematic diagram of a system for implementing a keyboard emulator using digital paper and a digital pen according to a first preferred embodiment of the present invention. Here, an emulator means an apparatus or a program for emulating and implementing a function of one hardware or software into another kind of hardware or software.

Although FIG. 3A illustrates the first information communication terminal 330 as a personal computer, the first information communication terminal 330 is not limited thereto, and includes a personal digital assistant (PDA), a mobile communication terminal, and the like. The emulator combined digital pen driver 332 is suitably programmed and installed according to the type of the first information communication terminal 330 including a personal computer, a PDA, a mobile communication terminal, and the like.

On the other hand, as shown in Figure 3a, a system for implementing a keyboard emulator using a digital paper and a digital pen according to a preferred embodiment of the present invention can be used in combination with the keyboard (110). That is, the scan code may be input through the keyboard 110 or the scan code may be input through the keyboard emulator according to the preferred embodiment of the present invention.

In the present invention, the keyboard emulator digital paper 310, as described in Figures 2a to 2q is displayed in the first cell 201 is represented by a binary or more binary number, through this unit The X, Y coordinate value or pattern ID of the cell pattern 210 is determined. In addition, in the present invention, the keyboard emulator digital paper 310 displays the keys of the keyboard 110 on the surface of the keyboard emulator digital paper 310, as shown in FIGS. 3B and 3C. The keys of the keyboard 110 displayed on the digital paper 310 can be visually confirmed. In the following description, the data is coded and displayed in the first cell 201 as shown in FIGS. 2A to 2Q and described on the basis of binary data.

When the keys of the keyboard 110 having a constant key arrangement as shown in FIG. 3B are displayed on the keyboard emulator digital paper 310 according to the preferred embodiment of the present invention, that is, the position display pattern described with reference to FIGS. Set part or all of the area of the general digital paper 200 divided by the X and Y coordinates of the unit cell pattern 210 as a keyboard-only area, that is, a large number of part or all of the location display patterns of the general digital paper 200. In the first case to which the keyboard area X and Y coordinate values are assigned, and the keyboard-only pattern different from the position display pattern described in FIGS. 2A to 2Q, that is, the sign of the binary data displayed in the first cell 201 is shown in FIG. Keyboard that displays the sign of the binary data in the first cell in another way (e.g., the length of the sign is different from that of FIG. 2m or the position of the code on the virtual X and Y axes is different from that of FIG. 2m) Private pattern (Hereinafter, the sign of the binary data displayed in the first cell in a manner different from the sign of the binary data displayed in the first cell as shown in FIG. 2M is referred to as a "keyboard only code"). Second case). In the second case, the keyboard-only pattern includes a keyboard-specific unit cell pattern including at least one first cell marked with a keyboard-only symbol, and for keyboard emulators with keyboard-only X and Y coordinates assigned to the keyboard-only unit cell pattern. The area of the digital paper 310 is divided.

On the other hand, when the keyboard keys are displayed on the keyboard emulator digital paper 310 as shown in FIG. 3C irrespective of a normal key arrangement, a keyboard having a pattern ID (Identity) specialized for each keyboard key on the keyboard emulator digital paper 310. There is a third case where a dedicated pattern ID is assigned. Here, the pattern ID is a unique ID given to the target display pattern 340 in which one or more unit cell patterns 210 are collected, and the binary data of one or more first cells 201 included in the single cell pattern 210. The pattern ID is represented by a combination of data corresponding to the sign of, and the single cell patterns 210 included in the target display pattern 340 represent the same pattern ID. In addition, the object display pattern 340 is a position display pattern for the digital pen 320 to recognize an object displayed on the digital emulator 310 for keyboard emulation so that the user can visually check.

As an example of the "ESC key" among the keyboard keys, the target display pattern 340 corresponding to the "ESC key" in FIG. 3D is a plurality of unit cell patterns 210 located in the area of the object called "ESC key". Are organized together. Here, the target display pattern 340 is a combination of data corresponding to the sign of the binary data displayed in the first cell 201 of the unit cell pattern 210 and corresponds to a unique pattern ID of the object, that is, an "ESC key". Is given a keyboard-specific pattern ID. The unit cell patterns 210 constituting the target display pattern 340 have the same keyboard-specific pattern ID. For example, when the keyboard-only pattern ID given to the target display pattern 340 corresponding to the "ESC key" is "003", the unit cell patterns 210 constituting the target display pattern 340 are each "003". "Represents the same keyboard-only pattern ID. Although not shown in FIG. 3D, it may be understood from the foregoing description that the unit cell pattern 210 includes a plurality of first cells 201 and a plurality of second cells 202.

In conclusion, the digital paper for keyboard emulator 310 of the present invention is manufactured in the same manner as in the first to third cases as described above, and used in a system for implementing a keyboard emulator according to a preferred embodiment of the present invention. Paper.

Meanwhile, the general digital paper 200 described with reference to FIGS. 2A to 2Q is a general area that is an area that is not manufactured in the same manner as in the first case to the third case, that is, an area including a position display pattern to which a keyboard area coordinate value is not given. And a code of binary data different from the keyboard only code, that is, the code of the binary data displayed in the same manner as in FIG. A digital paper to which a general pattern ID, which is another pattern ID, is assigned. Here, the position display pattern of the general area includes a coordinate value used in a digital pen application, which is an application for displaying a handwriting or a picture in a first telecommunication terminal when a handwriting or a picture is made on a digital paper by a keyboard emulator / digital pen. Gives a general coordinate value.

Thus, the user may write or write on the general digital paper 200 using the keyboard emulator-use digital pen 320 as shown in FIG. 5, or display the target display pattern displayed on the general digital paper 200 using the keyboard emulator-use digital pen ( 320).

In FIG. 3A, the keyboard emulator digital paper 310 and the general digital paper 200 are respectively independently present. However, when the present invention is actually applied, the keyboard emulator digital paper 310 and the general digital paper 200 are present. ) Can be printed on one article of manufacture.

That is, a keyboard area coordinate value is given to a position display pattern included in a part of one digital paper, and a general coordinate value is given to a general area, the other area. It includes a keyboard-only pattern, and the remaining area includes a general location display pattern, which is a conventional location display pattern, and a portion of one digital paper displays a keyboard-specific pattern ID, and the remaining area displays a general pattern ID. In one of the schemes, the digital paper 310 for keyboard emulator and the general digital paper 200 may be printed on a single product.

In the present invention, the keyboard emulator-compatible digital pen 320 may include a keyboard area X, Y coordinate value, keyboard dedicated X, Y coordinate value, and keyboard only pattern ID from the unit cell pattern 210 displayed on the keyboard emulator digital paper 310. Recognizes one piece of information, transmits it to the first information communication terminal 330, and recognizes the unit cell pattern 210 displayed on the general digital paper 200. 330 to transmit. That is, the keyboard emulator-compatible digital pen 320 recognizes information of any one of the keyboard area X, Y coordinate value, keyboard dedicated X, Y coordinate value, and keyboard dedicated pattern ID from the digital paper 310 for keyboard emulator. 1 by transmitting the information to the information communication terminal 330, the scan code corresponding to the information recognized by the digital emulator 320 combined with the keyboard emulator in the first information communication terminal 330 is currently activated in the first information communication terminal 330 The digital pen 320 combined with the keyboard emulator also recognizes the general X and Y coordinate values from the general digital paper 200 and transmits them to the first information communication terminal 330, thereby transmitting the first information communication. In the terminal 330, the user may display a handwriting or picture written on the digital paper 200 using the keyboard emulator / digital pen 320.

Although not illustrated in FIG. 3A, the digital pen 320 having a keyboard emulator includes an optical system / lens for optically inputting a position display pattern including a target display pattern 340 and a unit cell pattern 210. Image sensor for recognizing image, microprocessor for processing information input from image sensor, internal memory for storing certain information under control of microprocessor, and general purpose (USB) for communication with external device under control of microprocessor It is configured to include an interface.

In the present invention, the keyboard emulator-use digital pen 320 stores the keyboard area X and Y coordinate value ranges corresponding to the keyboard-only area in the internal memory, or the data corresponding to the keyboard-only code and the keyboard-only code (in the case of binary numbers, The exclusive code data of 0 or 1) is stored to process the data of the unit cell pattern 210 recognized from the keyboard emulator digital paper 310 as the keyboard area X, Y coordinate value or the keyboard dedicated X, Y coordinate.

In this case, when the keyboard emulator-compatible digital pen 320 stores the keyboard area X and Y coordinate value ranges, the keyboard emulator digital paper 310 converts a part or all of the area of the general digital paper 200 into a keyboard-only area. In this case, the keyboard emulator-compatible digital pen 320 stores the keyboard-specific code and dedicated code data in the keyboard emulator digital paper 310, which is different from the position display pattern described with reference to FIGS. 2A to 2Q. A pattern, i.e., a keyboard only code, which is a code of binary data displayed in a different manner from that of the binary data displayed in the first cell 201 as shown in FIG. 2M, is displayed. This is the case where the Y coordinate value is given to the digital paper 310 for keyboard emulator.

If this is described in more detail as follows.

The keyboard emulator-compatible digital pen 310 is connected to the digital paper 310 for the keyboard emulator through an optical system / lens and an image sensor in close proximity to a specific key among the keyboard keys displayed on the digital emulator 310 for the keyboard emulator shown in FIG. 3B. The position indication pattern is recognized, that is, the symbols of the first cell 201 and the second cell 202 of the keyboard emulator digital paper 310 are recognized. The recognition code, which is a code that recognizes the first cell 201, is processed as X and Y coordinates of the unit cell pattern 210 through a microprocessor. Here, the sign means a sign of binary data.

When the keyboard area X and Y coordinate value ranges are stored in the internal memory of the keyboard emulator-use digital pen 320, the microprocessor of the keyboard emulator-use digital pen 320 is manufactured in the same manner as in the first case. As a result of comparing the X, Y coordinate values recognized from 310 to the keyboard area X, Y coordinate value ranges stored in the internal memory, the X, Y coordinate values are located within the keyboard area X, Y coordinate value ranges, that is, X, Y If the coordinate value is the keyboard area X and Y coordinates, the first information communication terminal 330 to generate scan code conversion request information and describe the keyboard area X and Y coordinate value and scan code conversion request information through a universal interface (USB). To send). Here, the scan code change request information means information indicating that the keyboard area X, Y coordinate value or the keyboard dedicated X, Y coordinate value is a key input of the keyboard.

When the keyboard-only code and the dedicated code data are stored in the internal memory of the keyboard emulator-compatible digital pen 320, the keyboard emulator-compatible digital pen 320 is connected to the digital paper 310 for the keyboard emulator or the general through the optical system / lens and the image sensor. When the recognition code is a keyboard-only code by comparing the recognition code, which is a code recognized by the digital paper 200, and the keyboard-only code stored in the internal memory, the recognition code is converted to the keyboard-only X through a combination of dedicated code data corresponding to the recognition code. , Y coordinates, and generates scan code conversion request information, and transmits the keyboard-only X, Y coordinate values and scan code conversion request information to the first information communication terminal 330 to be described later through a universal (USB) interface. do. In this case, the digital paper 310 for keyboard emulator is manufactured in the same manner as in the second case.

Here, as a result of comparing the X and Y coordinate values with the keyboard area X and Y coordinate value ranges in the keyboard emulator digital pen 320, the X and Y coordinate values are not included in the keyboard area X and Y coordinate value ranges. When the keyboard emulator-compatible digital pen 320 recognizes the general X and Y coordinate values, which are the X and Y coordinate values included in the general area, from the general digital paper 200, the scan code is converted by the keyboard emulator digital pen 320. Instead of generating request information, only general X and Y coordinate values are transmitted to the first information communication terminal 330 which will be described later.

In addition, as a result of comparing the recognition code with the keyboard-only code in the keyboard emulator-use digital pen 320, the recognition code is not the keyboard-only code, that is, the keyboard emulator-use digital pen 320 uses the code from the general digital paper 200. In this case, the keyboard emulator digital pen 320 does not generate scan code conversion request information, and processes the recognition code as X and Y coordinate values, and then converts the X and Y coordinate values into the first information communication terminal 330. To send.

That is, the keyboard emulator-compatible digital pen 320 according to the preferred embodiment of the present invention can recognize both the information of the digital paper 310 and the general digital paper 200 for the keyboard emulator.

Meanwhile, in the present invention, the keyboard emulator-compatible digital pen 320 recognizes a keyboard-specific pattern ID indicated by each of the unit cell patterns 210 constituting the target display pattern 340, and as a first information communication terminal 330 to be described later. send. For example, if the keyboard emulator-compatible digital pen 320 is close to the "ESC key" among the keys of the keyboard shown in FIG. 3C, the keyboard emulator-use digital pen 320 is the target display pattern corresponding to the "ESC key". Among the unit cell patterns 210 constituting the 340, the code of the binary data displayed on any one unit cell pattern 210 is recognized and transmitted to the first information communication terminal 330.

In the present invention, the first information communication terminal 330 is an information communication terminal provided with a keyboard emulator / digital pen driver 332 according to a preferred embodiment of the present invention, and a keyboard emulator / digital pen driver 332 and a BIOS 124. , A buffer 126, and the like, and receive scan code conversion request information and keyboard area X and Y coordinate values from the keyboard emulator digital pen 320, or receive scan code conversion request information and keyboard dedicated X and Y coordinate values. Then, the keyboard emulator / digital pen driver 332 converts the keyboard area X, Y coordinate values or the keyboard-only X, Y coordinate values into scan codes corresponding to a specific key, and the BIOS 124 or the buffer 126. After sending it to the currently active application, it sends a specific keystroke in the currently active application. The ability to run.

Here, the keyboard emulator combined digital pen driver 332 installed in the first information communication terminal 330 may store the keyboard area X, Y coordinate values or keyboard dedicated X, Y coordinate values received from the keyboard emulator digital pen 320. The scan code is converted into the BIOS 124 or the buffer 126. To this end, the digital pen driver 332 combined with the keyboard emulator includes a coordinate / scan code conversion table for converting the keyboard area X and Y coordinate values or the keyboard dedicated X and Y coordinate values into scan codes as shown in FIG. 4A. .

The keyboard emulator-compatible digital pen driver 332 compares the keyboard area X, Y coordinate values or keyboard-only X, Y coordinate values received from the keyboard emulator digital pen 320 with the coordinate value scan code conversion table, and the keyboard area X , Y coordinates, or keyboard-only X, Y coordinates, the keyboard area X, Y coordinates or keyboard only X, The Y coordinate value is converted into a scan code corresponding to a specific X and Y coordinate value range.

For example, if the keyboard area X, Y coordinate value or the keyboard dedicated X, Y coordinate value is (160, 24), the keyboard emulator digital pen 320 compares it with the coordinate / scan code conversion table and as a result, If the keyboard area X, Y coordinate values or the keyboard-only X, Y coordinate values correspond to the X and Y coordinate value ranges of (151 to 170, 21 to 40) in the coordinate / scan code conversion table, then the keyboard area X , Y coordinate value or keyboard dedicated X, Y coordinate value is converted into a scan code "2" corresponding to the X and Y coordinate value range of (151 to 170, 21 to 40) in the coordinate / scan code conversion table.

In addition, when the first information communication terminal 330 receives the keyboard-only pattern ID from the keyboard emulator-use digital pen 320, the first communication terminal 330 scans the keyboard-only pattern ID corresponding to a specific key through the keyboard emulator-use digital pen driver 332. The code is converted into a code, transmitted to the BIOS 124 or the buffer 126, and then transmitted to the currently activated application to execute a function corresponding to a specific key input in the currently activated application.

Here, the keyboard emulator-use digital pen driver 332 converts the keyboard-only pattern ID received from the keyboard emulator-use digital pen 320 into a scan code and transmits it to the BIOS 124 or the buffer 126. To this end, the keyboard emulator-compatible digital pen driver 332 includes a pattern ID / scan code conversion table for converting a keyboard-specific pattern ID into a scan code as shown in FIG. 4B.

The keyboard emulator-compatible digital pen driver 332 compares the keyboard-only pattern ID received from the keyboard emulator-compatible digital pen 320 with the pattern ID / scan code conversion table, and the keyboard-only pattern ID is selected from the pattern ID / scan code conversion table. If the specific pattern ID matches, the pattern ID is converted into a scan code corresponding to the specific pattern ID.

For example, if the keyboard-only pattern ID is "002", the keyboard emulator-compatible digital pen 320 compares it with the pattern ID / scan code conversion table, and as a result, the keyboard-only pattern ID is selected from the pattern ID / scan code conversion table. If it matches "002" which is a specific pattern ID, it converts to "2" which is a scan code corresponding to "002" which is a specific pattern ID in the pattern ID / scan code conversion table.

Meanwhile, the first information communication terminal 330 receives only general X and Y coordinates without receiving scan code conversion request information from the keyboard emulator digital pen 320, or is not included in the pattern ID / scan code conversion table. Upon receiving the pattern ID, the keyboard emulator-compatible digital pen driver 332 does not convert the X, Y coordinate value or the general pattern ID into a scan code. Here, the application currently activated in the first information communication terminal 330 displays a handwriting or a figure written by the user on the digital paper with a digital pen on the information communication terminal as shown in FIG. 5, or the pattern recognized by the digital pen on the digital paper. If the digital pen application, which is an application for displaying information on the ID in the telecommunication terminal, the digital pen driver 332 combined with the keyboard emulator transmits the general X, Y coordinate values or the general pattern ID to the digital pen application, thereby providing the first information communication. The terminal 330 displays in real time a handwriting or a picture that the user writes on the general digital paper 200, or provides information corresponding to the general pattern ID.

In the present invention, for convenience of description, the keyboard emulator / digital pen 320 stores the keyboard area X and Y coordinate value ranges corresponding to the keyboard-only area in the internal memory, or the data corresponding to the keyboard-only code and the keyboard-only code. In this case, it is assumed that the data of the unit cell pattern 210 recognized from the keyboard emulator digital paper 310 is stored as the keyboard area X, Y coordinate value or the keyboard dedicated X, Y coordinate by storing dedicated sign data of 0 or 1). Although the present invention is limited, the first information communication terminal 330 may store the keyboard area X and Y coordinate value ranges or store the keyboard dedicated code and the dedicated code data.

When the first telecommunication terminal 330 stores the keyboard area X and Y coordinate value ranges, the first telecommunication terminal 330 receives the X and Y coordinate values from the digital pen 320 which is a keyboard emulator. After determining whether the Y coordinate value is included in the keyboard area X and Y coordinate value ranges, the X and Y coordinate values may be converted into scan codes when the X and Y coordinate values are included in the keyboard area X and Y coordinate value ranges. In this case, the keyboard emulator-compatible digital pen 320 does not store the keyboard area X and Y coordinate value ranges in the internal memory, and recognizes the keyboard area X and Y coordinate values from the keyboard emulator digital paper 310 or uses a general digital paper. Recognizes general X and Y coordinate values from 200 and performs only a function of transmitting them to the first information communication terminal 330.

When the keyboard dedicated code and the dedicated code data are stored in the first information communication terminal 330, the first information communication terminal 330 receives the recognition code from the digital pen 320 for the keyboard emulator, and the recognition code and the keyboard dedicated code. When the recognition code is a keyboard-only code, the recognition code may be processed into a keyboard-only X and Y coordinate through a combination of dedicated code data corresponding to the recognition code, and converted into a scan code. In this case, the keyboard emulator-compatible digital pen 320 does not store the keyboard-only code and dedicated code data in the internal memory, and recognizes the recognition code recognized from the keyboard emulator digital paper 310 or the general digital paper 200 first. It performs only a function of transmitting to the information communication terminal 330.

On the other hand, as a result of comparing the X, Y coordinate value or the recognition code with the keyboard area X, Y coordinate value range or the keyboard-only code in the first information communication terminal 330, the X, Y coordinate value or the recognition code is the keyboard area X, When the first information communication terminal 330 is not located within the Y coordinate value range or is not a keyboard-only code, that is, when the digital emulator-compatible digital pen 320 receives the information recognized from the general digital paper 200 by the first information communication terminal 330, 1 The information communication terminal 320 transmits the general X and Y coordinate values received from the keyboard emulator-use digital pen 320 to the digital pen application, or sends the recognition code received from the keyboard emulator-use digital pen 320 to the general X, Y. Process it as a Y coordinate and send it to the digital pen application.

4A is a table for converting keyboard area X, Y coordinate values or keyboard dedicated X, Y coordinate values into scan codes. The keyboard emulator / digital pen driver 332 installed in the first information communication terminal 330 is a keyboard emulator. When the scan code conversion request information and the keyboard area X and Y coordinate values or the scan code conversion request information and the keyboard dedicated X and Y coordinate values are received from the dual-purpose digital pen 320, the digital pen driver 332 converts the coordinate value scan codes. Compare the table and keyboard area X and Y coordinate values or the keyboard-specific X and Y coordinate values.

If the X coordinate value ranges from 101 to 120 and the Y coordinate value ranges from 21 to 40 among the keyboard area X and Y coordinate values or the keyboard only X and Y coordinate values, the keyboard emulator combined digital The pen driver 332 transmits the corresponding scan code "1" to the BIOS 124 or the buffer 126, and the range of the X coordinate value among the keyboard area X and Y coordinate values or the keyboard dedicated X and Y coordinate values. Is located between 126 and 145, and the Y coordinate value is between 21 and 40, the keyboard emulator-compatible digital pen driver 332 sends the corresponding scan code "2" to the BIOS 124 or the buffer 126. To be sent).

When the keyboard-specific pattern ID is "001", the digital pen driver 332 may use the keyboard emulator. Corresponding scan code “1” is transmitted to the BIOS 124 or the buffer 126.

FIG. 6 is a diagram schematically illustrating a system for implementing a keyboard emulator using digital paper and a digital pen according to a second preferred embodiment of the present invention.

A system for implementing a keyboard emulator using digital paper and a digital pen according to a second preferred embodiment of the present invention includes a keyboard display digital paper 610, a general digital pen 620, a second information communication terminal 630, and a digital pen. A driver 632, a key input application program interface (API) call program 634, and the like.

The keyboard display digital paper 610 may display keys of the keyboard in a specific area of the general digital paper 200 as shown in FIG. 3B, or the keys of the keyboard may be displayed regardless of a conventional key arrangement as shown in FIG. 3C. Are digital papers with different pattern IDs.

When the keyboard input API calling program 634 to be described later is activated in the second information communication terminal 630, the X, Y coordinate value or pattern ID included in the area of the keyboard display digital paper 610 is the keyboard input API calling program. The X, Y coordinate value or the pattern ID included in the keyboard display digital paper 610 is not converted into the scan code when it is converted into the scan code by 634 and the keyboard input API call program 634 is not activated. . In this case, the keyboard display digital paper 610 may be configured to allow the user to easily input scan codes for X, Y coordinate values or pattern IDs of a specific area while the keyboard input API call program is executed. Some or all of the areas show keyboard keys for visual confirmation.

On the other hand, even if the general digital paper 200, the keys of the keyboard is not displayed in some or all areas, in the state in which the keyboard input API call program is activated in the second information communication terminal 630, part or all of the general digital paper 200 The X, Y coordinate values included in the area or the pattern ID displayed on the digital paper 200 may be converted into scan codes by the keyboard input API calling program. However, since the user cannot visually check the keys of the keyboard in the general digital paper 200, the general digital pen will not accurately recognize the X, Y coordinate value or pattern ID corresponding to the scan code to be input by the user.

The general digital pen 620 only recognizes X, Y coordinate values or pattern IDs from the general digital paper 200 or the keyboard display digital paper 610 and transmits them to the second information communication terminal 630.

That is, the general digital pen 620 only recognizes X, Y coordinate values or pattern IDs from the general digital paper 200 or the keyboard display digital paper 610 and transmits them to the second information communication terminal 630, and the keyboard emulator. Like the combined digital pen 320, it does not perform a function of generating scan code conversion request information for converting an X, Y coordinate value or a pattern ID into a scan code. Thus, the general digital pen 620 does not need to store the keyboard area X and Y coordinate value ranges or the keyboard dedicated code and dedicated code data in the internal memory.

The second information communication terminal 630 is a personal computer or PDA or mobile communication terminal in which the digital pen driver 632 and the key input API calling program 634 are installed.

The digital pen driver 632 installed in the second information communication terminal 630 is a driver program of the general digital pen 620, and the key input API calling program 634 is not activated in the second information communication terminal 630. In this case, the second information communication terminal 630 receives an X, Y coordinate value or pattern ID from the general digital pen 620 through the digital pen driver 632, and transmits the same to the digital pen application.

For example, some or all of the keyboard display digital paper 620 in which the keys of the keyboard are displayed in some or all areas of the digital paper 200 or some or all of the general digital paper 200 in which the keys of the keyboard are not displayed in some or all areas. If the X, Y coordinate value or pattern ID in the area is received at the second information communication terminal 630, and the key input API calling program 634 is not activated at the second information communication terminal 630, the second information. The communication terminal 630 does not perform the scan code conversion process for the X, Y coordinate value or the pattern ID, and the user takes the keyboard display digital paper 620 or the general digital paper 200 with the general digital pen 620. The dot is displayed on the display 130 or information corresponding to the pattern ID is displayed.

When the key input API calling program 634 is activated in the second information communication terminal 630, the second information communication terminal 630 may be configured as X, X, from the general digital pen 620 through the digital pen driver 632. Receive a Y coordinate value or pattern ID and send it to a keystroke API call program 634. That is, when the key input API call program 634 is executed in the second information communication terminal 630, the digital pen driver 632 may use the digital pen to read X, Y coordinate values or a specific pattern ID received from the general digital pen 620. Rather than sending to the application, the key input API call program 634 is sent, and the key input API call program 634 performs a process for converting it into a scan code of the keyboard.

In the present invention, the key input API calling program 634 includes the coordinate / scan code conversion table of FIG. 4A or the pattern ID / scan code conversion table of FIG. 4B.

If the key input API call program 634 includes a coordinate / scan code conversion table, the key input API call program 634 is executed by the digital pen driver 632 from the digital pen driver 632 in an activated state in the second telecommunication terminal 630. Receives a Y coordinate value, compares the X and Y coordinate values with the coordinate / scan code conversion table, and compares the X and Y coordinate values with a specific X and Y coordinate value in the X, Y coordinate value range of the keyboard area of the coordinate / scan code conversion table. If the range, the X, Y coordinate value is converted into a scan code corresponding to a specific X, Y coordinate value range.

Meanwhile, if the X and Y coordinate values do not correspond to the keyboard area X and Y coordinate value ranges, the key input API calling program 634 does not convert the X and Y coordinate values into scan codes. At this time, if the digital pen application is activated in the second information communication terminal 630, the key input API call program 634 transmits X, Y coordinate values to the digital pen application.

If the key input API call program 634 includes a pattern ID / scan code conversion table, the key input API call program 634 is a pattern from the digital pen driver 632 in an activated state in the second telecommunication terminal 630. When the ID is received and the pattern ID is compared with the pattern ID / scan code conversion table and matches with any one specific pattern ID included in the pattern ID / scan code conversion table, the pattern ID is converted into a scan code corresponding to the specific pattern ID. To convert.

On the other hand, if the pattern ID does not match a specific pattern ID included in the pattern ID / scan code conversion table, the key input API call program 634 does not convert the pattern ID into a scan code. At this time, if the digital pen application is activated in the second information communication terminal 630, the key input API calling program 634 transmits the pattern ID to the digital pen application.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention.
