Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for inputting handwritten characters into a computer, and more particularly to a handwritten character input system characterized by its editing work.

[0002]

2. Description of the Related Art In recent years, a so-called pen input computer for inputting handwritten characters drawn with a stylus pen into a computer has attracted attention. In this type of computer, how to edit a character string once input is one of the important factors that affect the usability of the system. This is because one of the characteristics of computers is that they can be freely rewritten after the fact.

For example, NCR's 3125 pen computer is a computer in which a liquid crystal display device is laminated and arranged on an electromagnetic type tablet, and "Windows for Pen" of Microsoft Corporation in the United States is used.
s "(" Windows for Pens "is a trademark of Microsoft Corporation), which is an operating system for a pen computer. The operating system uses an editing system called "Edit Text Dialog Box". As shown in FIG. 12A, a part of a character string display screen of a window on an application, for example, a display screen 94 of a word processor, is written by an instruction in the edit text dialog box shown in FIG. 12B. When the editing work is moved to the area 95 and the OK button 98 is pointed at the end of the editing work, the contents of the writing area 95 are returned to the character string display screen 94 and the word processing document is edited.

[0004]

In the conventional editing method described above, the operation is troublesome because it is necessary to separately give an instruction to end the editing. Also, since the scroll function added to the writing area extends only to the character string transferred to the writing area in advance, when editing a character string in the vicinity of the editing work, the editing work is terminated once and then edited again. Because I have to give instructions for work,
Operation is troublesome.

An object of the present invention is to provide a handwritten character input system which is easy to edit and is easy to use from the viewpoint of a man-machine interface.

It is preferable that both the data in the character string data storage means and the data in the handwritten character display data storage means are updated based on the correspondence relationship.

It is effective that the contents of the reference means can be updated based on the coordinate value data sent from the coordinate detecting device to the central processing means.

Further, a scroll instruction area is provided on the coordinate detection surface of the coordinate detection apparatus, and coordinate values in the scroll instruction area are defined in the reference means based on being sent from the coordinate detection apparatus to the central processing means. The correspondence between the character string stored in the handwritten character display data storage means and the character string stored in the character string data storage means may be shifted by a predetermined value.

Further, a character string selection area is provided on the coordinate detection surface of the coordinate detection apparatus, and the coordinate means in the character string selection area is sent from the coordinate detection apparatus to the central processing means, whereby the reference means is provided. In accordance with the coordinate value detected by the coordinate detecting device, the correspondence between the character string stored in the handwritten character display data storage means and the character string stored in the character string data storage means defined in It is preferable to configure.

Further, the coordinate detection device and the display device are stacked and arranged, and a handwritten character input region on a coordinate detection surface of the coordinate detection device and a handwritten character display region on a display screen of the display device. Can be configured to match.

Further, the coordinate detection device and the display device are arranged in a stack, and the character string selection area on the coordinate detection surface of the coordinate detection device and the character string display area on the display screen of the display device coincide with each other.

Can be configured as follows.

[0014]

The handwritten character input system configured as described above works so that editing work can be performed with less operation.

Further, the object to be edited can be changed more quickly by scrolling or selecting a character string.

Furthermore, the stacked arrangement of the coordinate detection device and the display device serves to further improve the usability of handwritten character input.

[0017]

As for 0, a pressure-sensitive method, an electromagnetic induction method, an optical method, or the like can be applied regardless of the coordinate detection principle. However, when the coordinate detection device 30 is mounted on the display device 20, the sensor plate forming the coordinate detection surface needs to be transparent. On the contrary, when the coordinate detection device 30 is placed under the display device 20, it does not need to be transparent, but it must have a considerably high reading height. In particular, when the display device 20 is composed of a flat panel display device such as a so-called liquid crystal display or plasma display and is illuminated by a backlight device, the thickness of the display device and the thickness of the backlight device are added. It is necessary for the coordinate detection device to be able to read the coordinates from the height. The “position detecting device” (Japanese Patent Publication No. 2-53805) previously proposed by the applicant provides a coordinate detecting device that can withstand such use.

In this case, the power supply required for coordinate detection on the side of the coordinate detection device with a display device 50, drive of the display device, lighting of the backlight, etc. is supplied via the cable 18 to the computer main body 10.
Can be sourced from. At the same time, cable 1
8, the coordinate value detected by the coordinate detecting device 30 is sent to the computer main body 10, and the display content data displayed on the display device 20 is transferred from the computer main body 10 to the display device 2.
Transfers to 0 can be made.

FIG. 1B shows a state of the display screen 21 displayed on the display device 20. The character string display area 24 is an area for displaying all or a part of the character string already input by handwriting character input. The handwritten character display area 25 is an area for displaying a part of the character string displayed in the character string display area 24, and in the present embodiment, squares for eight characters are drawn and the stylus pen 32 is placed. In the squares other than the squares, the same character string as the character string displayed in a part of the character string display area 24 is displayed, and in the square where the stylus pen 32 is placed, the handwriting data itself stored in the handwriting buffer is displayed. it's shown. Here, the handwriting buffer is a memory provided by a command of a program in a work data area inside a central processing means provided in the computer main body 10 and for taking in coordinate value data before character recognition processing is performed. Is. In the square where the stylus pen 32 is placed, the handwriting of the handwritten character itself is displayed just like writing a character on a piece of paper with a pencil. The left scroll icon display area 26 displays a left scroll icon such as a left arrow, and the right scroll icon display area 27 displays a right scroll icon such as a right arrow.

In this embodiment, the display device 20 is stacked on the coordinate detecting device 30, and the display screen 21 overlaps with the coordinate detecting device tablet portion 31 (not shown). Similarly, the character string display area 24 is displayed in the coordinate detection device 3
0 overlaps the character string selection area 34 (not shown), the handwritten character display area 25 overlaps the handwritten character input area 35 of the coordinate detection device 30, and the left scroll icon display area 26 overlaps the left scroll instruction area 36. The right scroll icon display area 27 overlaps with the right scroll instruction area 37.

FIG. 2 is a block diagram showing a device configuration of the handwritten character input system according to the present invention. The central processing means 11 is a so-called CPU, but here is a CP in a narrow sense.
U, that is, the most essential part of the means for executing the processing of this system. Program storage means 13,
There is a concept that the character string storage unit 14 and the reference unit 19 are regarded as a CPU in a broad sense, but in the present specification, they are considered separately for convenience. It is considered that a work data area for a handwriting buffer etc. is also provided in the main storage means. The program storage means 13 is a means for storing a handwritten character input program including not only character recognition processing but also edit processing such as display position change processing and scroll processing. The program storage means 13 constitutes a main storage means, and the program written in the program storage means 13 continuously sends commands to the central processing means 11 during the operation of the present system, and the central processing means 11 During the operation of this system, it constantly receives instructions of the program in the program storage means 13. Therefore, the program storage means 13 is different from the secondary storage means such as a hard disk or a floppy disk. Needless to say, this program can be stored in a secondary storage means (not shown). The character string data storage means 14 is a storage means for storing a character string desired to be input by the user of the present system as a recognition result after character recognition, and belongs to the main storage means. Further, the main storage means has a reference means 19. This is the character string data storage means 14
The data for defining the correspondence between the character string data stored in (1) and the character string data stored in the display content data storage means 16 described later is stored.

A display device control means 15 and a serial signal control means 17 are connected to the bus 12 of the central processing means 11. The display device control means 15 is a so-called liquid crystal controller when the display device 20 is a so-called liquid crystal display device. CRT if the display device 20 is a CRT
It becomes a control circuit. Display content data storage means 1
Reference numeral 6 denotes a so-called video RAM, and the display device control means 15 temporarily stores the display content data sent from the central processing means 11 in the display content data storage means 16 and rewrites the display of the display device 20. The data is transmitted to the display device 20 after being synchronized with the timing of. When the present system is configured so that all the devices are included in the integrated housing, there is no particular data transfer problem between the display device control means 15 and the display device 20, but FIG.
In the case where the display device control means 15 is provided on the computer main body 10 side in the embodiment shown in (A), the control signal, display content data, etc. sent from the display device control means 15 are compressed and the like. It is desirable to transfer to the 20 side.

The serial signal control means 17 is an interface circuit for sending the coordinate value data from the coordinate detection device 30 to the central processing means 11. The coordinate detection device control unit 33 is a control circuit that performs processing such as calculation of coordinate values based on the data detected by the coordinate detection device tablet unit 31 and sends the coordinate value data to the serial signal control unit 17 via the cable 18. . The coordinate detection device tablet unit 31
It is generally composed of a sensor plate including a coordinate detection surface, and when the coordinate detection principle of the coordinate detection device 30 is an electromagnetic induction system, it is a printed circuit board on which a large number of conducting wires are fixed.

FIG. 3 is a diagram showing an example of reference means constituting the handwritten character input system according to the present invention. FIG. 3A shows a character string selection coordinate table. Here, the character string selection coordinate table can display the character string selection area 34 of the coordinate detection areas on the coordinate detection surface of the coordinate detection device 30 in the character string display area 24 of the display screen 21 of the display device 20. It is a table that divides by the number of characters and associates each divided area with the index of the character string buffer. The index of the character string buffer here constitutes the character string data stored in the character string data storage means 14 shown in FIG. 2, and is a number assigned to each character of the character string. In the embodiment shown in FIG. 1B, since the display screen 21 is configured to display four lines with 14 characters per line, 56 characters can be displayed. Accordingly, the character string selection area 34 is also divided into 56 areas, and each area is associated with the index of the character string buffer. Each area divided into 56 areas is specified by, for example, 4 of X coordinate upper limit value, X coordinate lower limit value, Y coordinate upper limit value, and Y coordinate lower limit value as shown in FIG. 3C.
This is done with individual coordinate values.

FIG. 3B shows a handwritten character input coordinate table. Here, the handwritten character input coordinate table is the number of characters that can be displayed in the handwritten character input area 35 of the coordinate detection area of the coordinate detection device 30 in the handwritten character display area of the display screen 21 of the display device 20. Is a table in which each divided area is associated with an index number j of the handwriting character input pointer table. Here, the handwriting character input pointer table is shown in FIG. 3E, and the index number j is associated with the index number i of the character string buffer. In this embodiment, 10 areas including the left scroll instruction area 36 and the right scroll instruction area 37 in addition to the 8 areas where handwritten characters can be input are selected from [0] by the handwritten character input coordinate table. [9]
Are associated with the 10 index numbers [j], and among them, 8 indexes from j = 1 to j = 8 are associated with the indexes of the character string buffer by the handwriting character input pointer table. Each area divided into 10 areas is specified by four coordinate values such as an X coordinate upper limit value, an X coordinate lower limit value, a Y coordinate upper limit value, and a Y coordinate lower limit value, as shown in FIG. 3C. It

FIG. 3D shows the state of the character string buffer, that is, the state of the data stored in the character string data storage means 14. Character string data obtained as a result of handwritten character recognition is stored in the character string buffer as a combination of data specifying the content of each character and the index number of the character. In the state shown in FIG. 1, 39 characters of "The word processor can be operated by handwriting without using the keyboard due to the progress of the pen computer" start from i = 0 in the index [i] of the character string buffer. It is stored in the part up to i = 38. In i = 34, the character "judo" is i = 3
The character of "work" is stored in 5. The part after i = 39 is blank as a non-input part. In the present embodiment, the number of characters that can be stored in the character string buffer is set to be the same as 56, which is the number of characters that can be displayed in the character string display area, but other embodiments that are larger than that number are also possible. Is. In that case, just as the handwritten character input pointer table associates the index of the handwritten character input coordinate table with the index of the character string buffer, another pointer table that should be called a character string selection pointer table is prepared. Then, the index of the character string selection coordinate table and the index of the character string buffer can be associated with each other. In the following description, in order to avoid complication, the number of characters that can be stored in the character string buffer and the number of characters that can be displayed in the character string display area are the same in this specification.

FIG. 4 is a flowchart showing the processing contents of the central processing means constituting the handwritten character input system according to the present invention. Now, when the present system is activated and the stylus pen 32 is used to indicate a point on the coordinate detection device tablet unit 31 of the coordinate detection device 30, the coordinate detection device control unit 33 detects the coordinate value. , And is sent to the central processing means 11 via the serial signal control means 17 (Step 1). First, it is determined whether or not the coordinate value data is within the character string selection area (Step 2), and if it is within the character string selection area, the display position changing process is executed. The contents of the display position changing process are shown in FIG. 5, which will be described later. If it is not in the character string selection area, it is judged whether or not it is the handwriting character input area (Step 3), and if it is in the handwriting character input area, character input processing is executed. The character input process is shown in FIG. 6 described later. If it is not in the handwriting character input area, it is determined whether it is in the left scroll instruction area (Step 4), and if it is in the left scroll instruction area, the left scroll processing is executed. The contents of the left scroll process are shown in FIG. 7 described later. If it is not in the left scroll instruction area, it is determined whether it is in the right scroll instruction area (Step 5), and if it is in the right scroll instruction area, right scroll processing is executed. The right scroll processing is shown in FIG. 8 described later. When it is not in the right scroll instruction area and when the display position changing process, the character input process, the left scroll process, and the right scroll process are completed, the process returns (Step 6).

FIG. 5 is a flow chart showing the contents of the display position changing process shown in FIG. Step 2 shown in FIG.
If YES is determined, the flow goes to the display position changing process shown in FIG. 5 (Step 21). First, the character string selection coordinate table shown in FIG. 3A is searched to obtain the index number i of the corresponding character string buffer (Step 2).
2). For example, the character string display area 2 shown in FIG.
When the position of the "row" displayed in 4 is designated by the stylus pen 32, that position corresponds to the 10th character region of the 3rd line in the character string display region 24, which is stacked on the display device 20. In the character string selection area 34 of the arranged coordinate detection device 30, according to the character string selection coordinate table,
This corresponds to the index number of i = 37. In this case, S
The process shown in step 22 means obtaining the index number of i = 37.

Next, the contents from the character string buffer [i-3] to the character string buffer [i + 4] are displayed in the handwritten character display area 2
5 is displayed (Step 23). In the embodiment shown in FIG. 1, for i = 37, the contents from the character string buffer [34] to the character string buffer [41], that is, "the operation is not performed".
The characters and blanks are displayed for three characters.

Next, the handwritten character input pointer tables [1] to [8] are assigned numerical values from i-3 to i + 4 (Step 24). In the example shown in FIG. 1, the numerical values 34 to 41 are respectively substituted into the handwriting character input pointer tables [1] to [8]. By this processing, FIG.
The handwritten character input pointer table is updated as shown in (E).

When this series of processing is completed, the display position changing processing is completed and the next coordinate input is awaited via Step 25 and Step 6.

FIG. 6 is a flow chart showing the contents of the character input processing shown in FIG. In Step 3 shown in FIG. 4,
If it is determined that the coordinate values are within the handwritten character input area, the character input processing shown in FIG. 6 is started (Step 31).
First, the handwriting character input coordinate table is searched to obtain the index number j of the corresponding handwriting character input pointer table (Step 32). In the example shown in FIG. 1, since the stylus pen 32 is at the position corresponding to the index number j = 6, j = 6 is obtained.

Next, the content of the handwritten character input pointer table [j] is set to i (Step 33). In the example of FIG. 1, the content 39 of the handwriting character input pointer table [6] is i. That is, i = 39.

Next, it is determined whether the input of one character is completed (Step 34). Specifically, there are a method of making a judgment with a stylus pen-up, a method of making a judgment when moving to an adjacent square, and the like. If one character has not been input, the input coordinate value is stored in the handwriting buffer (Step 39). S is stored in the handwriting buffer
step39, Step40, Step3, Step31
And so on. Here, the handwriting buffer is a buffer provided in the work data area 9 in the main storage unit 8 shown in FIG. 2, and temporarily stores the data to be character-recognized. The format of the data in the handwriting buffer differs depending on the method of character recognition. For example, in the case of the pattern matching method, it is close to the coordinate data set itself, but in the case of the stroke matching method, in addition to that, data indicating the input order is used in combination with the coordinate value. Note that, as shown in FIG. 1, the data stored in the handwriting buffer can be displayed in a corresponding square before the character recognition processing, but since it is not directly related to the present invention, the flowchart shown in FIG. Is omitted.

When the input of one character is detected by repeating the above coordinate input and the storage in the handwriting buffer several times (S
Character recognition processing is performed based on the contents of the handwriting buffer (Step 34) (Step 35). The character recognition program itself can be applied to any existing program.

When the character recognition processing is completed, the recognized character C is displayed in the corresponding handwritten character display area (Step).
36). In the example of FIG. 1, after recognizing the character “e”, “e” is displayed in the corresponding square. Next, the character C is stored in the corresponding character string buffer (Step 37).
In the example of FIG. 1, the character "e" is added to the character string buffer [3
9]. That is, character string buffer [39] = "e"
Becomes Further, the character C is displayed in the corresponding character string display area (Step 38). In the example of FIG. 1, the character “e” is displayed at the 12th character on the third line in the character string display area 24. After a series of these processes is performed, the process returns (St
ep40).

The character input processing has been described above with respect to the case of newly inputting a character in the blank portion as shown in FIG. 1. However, the editing work such as overwriting the portion where the character has already been input is the same processing as above. Can be done by

FIG. 7 is a flow chart showing the contents of the left scroll process shown in FIG. Step 4 shown in FIG.
If the coordinate value is in the left scroll instruction area, the processing is started (Step 41). In Step 42, it is determined whether the immediately preceding coordinate value is also the left scroll instruction area, and if not, the processing of Step 43 and Step 44 is executed. This is to prevent the scroll from being executed several times in succession against the intention of the operator.

Specifically, the left scroll process is performed by subtracting the value of each pointer of the handwriting character input pointer table by 3 (Step 43), and the contents of the character string buffer pointed by each pointer of the handwriting character input pointer table. , Is displayed in the handwritten character display area (Step 44). That is, the contents of the handwriting character input pointer table are changed and the display contents of the handwriting character display area are changed. In the example of FIG. 1, the content of the index [1] of the handwriting character input pointer table is rewritten to 31 by performing the left scroll, and the display content of the handwriting character display area 25 is “- It changes to ". After this series of processing, the process returns (Step 45).

FIG. 8 is a flowchart showing the contents of the right scroll process shown in FIG. The right scroll processing has the same contents as the left scroll processing, and is performed by adding 3 to the value of each pointer in the handwriting input pointer table. It should be noted that the setting of plus 3 or minus 3 at the time of scrolling is not necessarily limited to this value, and another value can be set. This value can be fixed in advance by a program, or the user can be given a choice.

FIG. 9 is a perspective view showing the second embodiment. In the embodiment shown in FIG. 1, the display device 20 is arranged to be stacked on the coordinate detection device 30, but in FIG. 9, the display device 20 is not stacked on the coordinate detection device 30, and the CRT is not provided. Other display devices 40 such as the above are provided, and a character string display region 44, a handwritten character display region 45, a left scroll icon display region 46 and a right scroll icon display region 47 are provided on the display screen 41 of the display device 40. . This is an example in which this system is configured without using a liquid crystal display device or the like. In this case, the character string selection area 3 is provided in the housing of the coordinate detection device tablet unit 31 of the coordinate detection device 30.
4, handwritten character input area 35, left scroll instruction area 36
Also, it is convenient that the grid indicating the right scroll instruction area 37 is printed, or those printed menu sheets are placed. Even if there is no square on the tablet, the display device 40
It is possible to input handwritten characters while looking at the screen, but it is considered that writing characters in squares is more suitable for the feeling of handwriting input.

FIG. 10 is a perspective view showing the third embodiment. In this embodiment, the CR device is used as a device constituting the embodiment of FIG.
In addition to the T display device 40, the same display content as the display device 20 is displayed on the display device 40.

This is an advantageous embodiment when it is desired to increase the number of characters displayed in and to make the liquid crystal smaller.

[0044]

The handwritten character input system according to the present invention is configured as described above, and by inputting the handwritten character while looking at the characters before and after the input, the character string data and the handwritten character display. Since both the data and the data are updated by one operation, the editing work can be performed in a lesser number of steps, which is convenient from the viewpoint of the man-machine interface.

Further, by updating both the character string data and the handwritten character display data based on the reference means, there is no waste in the processing executed by the central processing means.

Furthermore, since the contents of the reference means can be updated by the coordinate value data, the editing target can be changed easily.

In particular, by providing the scroll instruction area on the coordinate detection surface, it becomes easy to edit the portions before and after the data displayed in the handwritten character display area.

Further, by providing the character string selection area on the coordinate detection surface, it becomes possible to directly select a character string desired to be edited from a wider character string data, not just immediately before and after.

By matching the handwritten character input area with the handwritten character display area, the above-described editing work can be performed as if a character were to be written on a paper with a pencil.

By matching the character string selection area and the character string display area, the above-mentioned editing work can be performed without moving the line of sight between the hand and the screen.

By displaying the scroll icon over the scroll instruction area, the above editing work can be performed without using a menu sheet or the like.

When another display device such as a CRT is used together, the liquid crystal display device laminated on the coordinate detecting device only needs to cover the character string display area, and is therefore economical.
