Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an online handwritten character input method in an information processing device such as a computer, and particularly to an online handwritten character input method suitable for inputting fixed forms such as slips.

[Prior Art] Research has been progressing to efficiently perform office processes such as inputting slips by using online handwritten character input devices that have a fast input speed and are easy to learn. For example, in addition to matching with dictionaries, it is possible to ease writing restrictions by performing identification processing between similar characters, use a thermal tablet that does not require a special pen, or use a transparent tablet. A method has been proposed, such as placing the original picture below and inputting it.

In addition, in the device described in Japanese Patent Application Laid-open No. 61-243581, an input canister area setting switch (three types: large, medium, and small) is provided to set the area of the input canister (large, medium, and small), and the area of the input canister of the tablet can be set. Operator can choose.

In such a device, when inputting a format such as a slip, for example, when the number of input items is large, the area of each input field is set to be smaller than the display area of the display.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, when the number of input items is large compared to the display area of the display, each input field becomes small, making it difficult to write characters and potentially reducing the character recognition rate.

In addition, the operator must be careful not to overflow the input field, which poses a problem of heavy burden on the operator.

The purpose of the present invention is to improve such problems, and when inputting a form such as a slip, the burden on the operator increases even if the number of input items is large and the area of each input field is small. The purpose of the present invention is to provide an online handwritten character input method that does not require manual input.

[Means to solve the problem]

In order to achieve the above object, the online handwritten character input method of the present invention includes a coordinate input means (coordinate input device) having a stylus pen, and a character pattern formed by a coordinate data group of characters input from the coordinate input device. and a character recognition unit (character recognition unit) that outputs the character code of the closest dictionary pattern as a recognition result by comparing it with a pre-stored standard dictionary pattern, and displays a fixed format including a plurality of input items and input fields. means (display device), reads the coordinates specified by the stylus pen in the display area of the display device, recognizes the characters input with the stylus pen in the input field with the character recognition section, and displays the characters on the display. In the input method of online handwritten character input device,
Detects the target input item from the above indicated coordinates, sets the input field indicated by the input item as input mode, enlarges and displays only that input field at a predetermined magnification, and includes the input result after completing input to the input field. It is characterized by displaying the entire fixed format in its original size.

Further, when performing the enlarged display, the area is enlarged based on the position of the input field on the fixed format to be the target, and the target input field is overwritten and displayed.

Another feature is that the fixed format to be displayed on the display means is downloaded from the host device.

In addition, the fixed format downloaded from the above-mentioned host device has recognition control information for the display area, and each input field has attributes related to recognition to narrow down the recognition target including the characters and character strings entered in the input field. There are certain characteristics.

[Function] In the present invention, only one input field can be enlarged to a sufficient area, so even when there are many input items and the area of the input field is small, the character recognition rate decreases because it is difficult to write characters. There is no longer a need for the operator to be careful not to overflow the input field, and the burden on the operator can be reduced.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

The input display area 14 is a menu area. The blocks 5 to 9 are a series of processing units that perform character recognition and editing processing based on data from the coordinate input device 3, and are realized by the microcomputer 15 in this embodiment.

In the menu area 14 of this embodiment, command menus such as an edit menu for insertion/deletion, etc., and a transmission menu for transmitting an input character string to a host device are set.

Further, the coordinate input device 3 samples input from the stylus pen 4 and outputs designated coordinate data to the coordinate analysis section 5.

Further, coordinate analysis #5 identifies which region of the character input display area 13 or the menu area 14 on the input display integrated display 1 the coordinate data belongs to. As a result, if the coordinate data is data in the input field of the character input display area 13 and the input field is in input mode,
The coordinate data is sent to the character recognition section 6, and at the same time, it is converted into handwriting data and written into the video memory 10. Further, if the data from the coordinate input device 3 is coordinate data of the menu area 14, the menu contents are analyzed and the command is output to the editing processing section 7.

Furthermore, the display control unit 11 displays the contents of the video memory IO on the display device 2, and the handwriting is displayed at the position indicated by the pen on the display device 2, for example, as if it were written with a pen on paper.

Further, the character recognition unit 6 performs character recognition on the data sent from the coordinate analysis unit 5 by comparing the input character pattern formed by the stroke coordinate data with a standard character pattern stored in the character recognition unit 6 in advance. , outputs the character code of the recognition result to the editing processing section 7.

Further, the editing processing section 7 stores the character code passed from the character recognition section 6 at an address in the character code memory 8 corresponding to the input position in the character input display area 13. Also,
Erase the handwriting already displayed in the character display area 13,
In order to display the recognition result, the handwriting data in the video memory 10 is erased, and the character font data of the character code held in the editing processing section 7 is written to the address. Note that when a command from the menu area 14 is received, editing processing and communication processing according to the command are executed.

Next, the display and input of fixed formats such as slips to the character input display area 13 will be described.

FIG. 3 is an explanatory diagram of format data and display character data of the character input display area in the first embodiment of the present invention.

In FIG. 3, (a) shows an example of format data of the character input display area 13, (C) shows an example of displayed character data, and (b) shows the positional relationship in the character display area 13. Note that these data are downloaded from the host device to the online handwritten character input device.

In (a), TN is the format data identification number, NFLD is the number of fields that define the format (total of input item names and input fields), and IN is an item indicating the input item consisting of the input item name and input field. The number, L, is the field length (the number of characters that can be displayed or entered in the field). In addition, X and Y are the leftmost coordinates of the field, and in the character input display area 13, X indicates a column and Y indicates a row.6 Therefore, the field area is defined by the field length and coordinates (x, y). There is. Also, ATT is
This is a field attribute and specifies whether the field is an input item name or an input field. In this case, 00H is the input item name,
01M means an input field.

Furthermore, in (C), FN is a field number and indicates the field number from which display character data is downloaded. In addition, LC is the data length of display character data, Cod
e is a display character code.

As a result, the character data "TEL" and "Name""Address" are displayed in the first, third, and fifth fields, which are the input field of the format data in (a), respectively.

Moreover, in (b), 13a is an input item name, and 13b is a ruled line display of a frame of an input field.

When such format data and display character data are downloaded, the communication control unit 1 shown in FIG.
2, the format data is stored in the attribute memory 9, and the display character data is stored in the character code memory 8.

When the format data is stored in the attribute memory 9, the editing processing section 7 takes in this data. If the field attribute ATT in No. 311(a) indicates an input field, the video memory 10 is configured to display the input field ruled lines defined by the format data L, X, and Y on the character input display area 13. Write the ruled line data.

In (a), the second field is an input field, and the ruled line display result of this frame is shown as 13b in (b). In this case, format data L (=OB, 4),
As shown by (=04H) and Y (=02H), the ruled line of the input field for 11 characters is displayed with the left end located at the position of 4th column and 2nd row.

Further, the display character data in the character code memory 8 is read into the editing processing section 7, and the character font data is read in order to sequentially display the display character code Code from the position of the format data X and Y corresponding to the field number FN. Write to a predetermined address in the video memory 10.

For example, the data display result of field number l in (C) is shown as 13a in (b). In this case, the character "place" is displayed from the position of the first column and second row indicated by the first field (7)X (=O1)l), Y (=12M).

Next, a description will be given of the processing when inputting characters into a format obtained by downloading the format data (a) and the display character data (c) from a host device.

FIG. 1 is a flowchart showing processing during character input in the first embodiment of the present invention, and FIGS. 4 and 5 are screen display examples during character input in the first embodiment of the present invention. .

In this embodiment, when the format data and display character data shown in FIG. 3 are downloaded from the host device, the format shown in FIG.
displayed above. Note that 14a and 14b indicate command menus.

In the state shown in FIG. 4, the operator cannot input characters in the input field, so as shown in FIG.
1).

The coordinate analysis unit 5 reads the designated coordinates from the coordinate input device 3 and uses the format data L, X, Y of the attribute memory 9 to determine the item number IN of the designated input item.
102), and outputs this item number IN and an operator input request command to the editing processing section 7.

When the editing processing unit 7 receives the input request command, it searches and reads the input item name field and input column field corresponding to the item number IN from the format data ATT in the attribute memory 9 based on the item number IN. , Furthermore, the display character code Code corresponding to the input item name field is read from the character code memory 8. Then, the character font of this display character code is enlarged twice vertically and horizontally, and displayed as the input item name in the upper left corner of the character input display area, and then the input character frame is expanded vertically and horizontally in the same way by the field length of the input field field. Display at double magnification (
103). At this time, the input character frame is divided into characters and displayed with ruled lines.

Further, the coordinate analysis section 5 also switches to a coordinate analysis state corresponding to the display in the character input display area 13, and the input field becomes an input mode (104).

For example, on the display screen shown in FIG. 4, if the item name "address °'" of the address input item or the input field is indicated with the stylus pen 4, the display in the character input display area 13 becomes as shown in FIG. 5. Note that if the input item name and input field cannot fit on one line, they will be wrapped and displayed on the second and subsequent lines.

In this way, when the input field is switched to the enlarged input mode, the input field is switched to the coordinate mode in which the coordinate input to the input character frame is determined to be a character, and character recognition processing is performed as described above.

Further, the input result is displayed in print at the input position and simultaneously stored at the address corresponding to the input position in the character code memory 8 (105, 106).

Here, in the menu area 14, click "Paper completed" menu 14.
When you specify a with stylus pen 4, (107) 1, 4th
Return to displaying all diagram formats (108)
. In this case, the recognition results are also reduced and displayed in the original size character font.

In this way, when a character is input in the input field and the 1'Send" menu 14b is designated, the recognition result stored in the character code memory 8 is transmitted to the host device via the communication control section 12.

In this embodiment, when inputting characters into the input field, the input character frame is enlarged twice in the vertical and horizontal directions and four times in area, but the enlargement magnification can be set arbitrarily.

In addition, although the format data of the character input display area 13 and the display character data of the input item names are downloaded from the host device, there are multiple types stored in the device in advance.
It is also possible to make the selection possible according to instructions from the operator.

Furthermore, although one item number is configured with one input item name field and one input column field, it is also possible to have only one input field, or to have multiple fields for both the input item name and the input column.

Next, a second embodiment of the present invention will be described.

FIG. 6 is an example of a screen display during character input in the second embodiment of the present invention, and FIG. 7 is an explanatory diagram of format data of the character input display area in the second embodiment of the present invention. Note that the configuration is the same as the online handwritten character input device in the first embodiment (FIG. 2).

In this embodiment, when enlarging and displaying input items and input character frames, as shown in FIG. and override the enlarged display of the input text frame.

In this case, the character input method is exactly the same as in the first embodiment, but even if you use the stylus pen 4 to indicate the input item name or input field in the normal display that is not enlarged, it will be invalid.
The coordinate analysis mode of the character input display area 13 is switched so that only input to the input character frame is valid.

In the first embodiment, the display of the entire format is once erased, and the input items and input character frames are enlarged and displayed from the upper left of the character input display area 13, as shown in FIG.

Further, as shown in FIG. 7, format data including recognition control information is downloaded from the host device, and each input field is given an attribute for recognition to narrow down the objects to be recognized for the input characters or character strings.

In FIG. 7, ATT is field recognition attribute data added to the format data shown in FIG. 3(a). Also, similar to (a), FIG. 7 shows format data of the format shown in FIG. 4.

In this case, if ATT is OOH, “input prohibited”, O
1, 1 means ``phone number input limited'', and 028 means ``no input limited''.

In this embodiment, an input prohibition attribute is specified in the input item name field of the 1.3.5 field, and even if input is made, handwriting is not displayed and character recognition is not performed. Further, a telephone number input restriction attribute is specified in the second field, which limits the recognition of input characters to numbers, rejects other character types, and at the same time rejects input of characters other than O as the first character. Furthermore, the 4.6th field is a field with no input restrictions, and all types of characters can be input.

According to this embodiment, even if the display area of the display device is small and the input field needs to be displayed small in order to display a large number of input item names and input fields, when entering characters into the input field, the input field The area can be easily expanded, making it easier for the inputter to write, improving input efficiency.

〔Effect of the invention〕

According to the present invention, the display area for displaying forms such as slips is small, and in order to display a large number of characters and input fields, it is necessary to display the input field small, and as a result, it becomes impossible to input into the input field. Even in such a case, the input field can be easily enlarged according to the operator's instructions, so the display area of the display device can be used effectively and input efficiency can be improved.

In addition, input results in input fields other than the input field in which the operator is inputting can be seen, and the operator can confirm the input results, thereby improving input efficiency.

Furthermore, since forms can be downloaded from a host device, various forms can be processed with one online handwritten input device.

Furthermore, by downloading a fixed format that includes recognition control information and assigning recognition-related attributes to each input field, you can narrow down the targets for recognition of characters or character strings entered in the input field, so you can recognize each input individually. rate and improve input efficiency.
