CHARACTER INPUT DEVICE, CHARACTER INPUT METHOD, AND CHARACTER INPUT PROGRAM}

The present invention relates to a character input device, a character input method, and a character input program. In particular, the present invention relates to a character input device for recognizing characters from handwriting.

Conventionally, a character input device capable of inputting handwritten characters is known. For example, when the character string " 12 at tomorrow " is input by handwriting using a stylus pen or the like, if the handwriting of " 12 " is written in the character input area of one character, Quot; 1 " and " 2 "

As a prior art of this kind, there is known a character recognition apparatus capable of recognizing even when a plurality of numbers are input into one character region (see Patent Document 1).

Japanese Patent Application Laid-Open No. 6-236454

However, in the conventional character input device, for example, when the focus or the cursor is moved from the right side to the inputted character string "at 12 o'clock tomorrow", "time" → "2" → "1" → " &Quot;, " That is, for the character " 12 " input by the user, the character to which the focus is set is "1" or "2", and inconsistency with the input character occurs. For this reason, the user has a sense of incongruity. This is true not only for the movement of the focus or the cursor, but also for the case of deleting one character or rewriting.

As described above, conventionally, no consideration has been given to how to handle a recognized character in editing or display.

A character input device, a character input method, and a character input program according to an embodiment of the present invention will be described below with reference to the drawings. The character input device of the present embodiment is applied to an electronic device having a handwriting input function.

(First Embodiment) Fig.

1 is a block diagram showing a configuration example of a character input device 1 according to a first embodiment of the present invention. The character input device 1 includes a handwriting input unit 11, a character recognition unit 12, a control unit 13, a character display unit 14, and a user operation unit 15.

The handwriting inputting section 11 is constituted by a touch panel provided on the screen of the character display section 14 and inputs a handwriting of the user written in the character entry area 11a (see FIG. 2 described later) by using a stylus pen or the like . Further, the touch panel may be of a contact type or of a press type.

The character recognition unit 12 recognizes the character from the handwriting input by the handwriting input unit 11. The character recognition unit 12 is provided with a memory 12a for storing handwritten or candidate character groups such as "00" to "99" input by the handwriting input unit 11 and character codes corresponding to handwriting , Unicode) are registered in the database 12b. The database 12b holds a character code (for example, a character code corresponding to "12") corresponding to a plurality of characters as a special code. The character recognition unit 12 recognizes not only a character of one character written in the character entry area 11a (predetermined area) but also a character string of a plurality of digits and the like, Character string) from the database 12b and stores the special code in the memory 12a.

The character recognition unit 12 also notifies the control unit 13 of the character code of the recognized character. If the recognized character is a number of a plurality of digits, the character code of each number is acquired from the special code corresponding to the digits of the plurality of digits, and the control unit 13 is notified. In this example, although a plurality of digits are held as a string, a string may be composed of a plurality of alphabets or hiragana, as will be described later.

The control unit 13 receives the character code recognized by the character recognition unit 12 and stored in the memory 12a. Based on the character code, the control unit 13 controls the cursor position and the focus position in accordance with the event of the user operation unit 15, and displays or rewrites the recognition candidate. That is, the control unit 13 controls the character display unit 14 of the character string at the time of display or editing according to the number of characters of the character string recognized by the character recognition unit 12.

The control section 13 is provided with a memory 13a, a focus / cursor position control section 13b for controlling the movement of focus and a cursor to be described later, and a character recognition control section 13c for controlling the character recognition section 12 .

When a plurality of numbers are written in the character entry area 11a, the control unit 13 stores the handwriting of individual numbers such as "1" and "2" in the memory 13a. The control unit 13 also receives the character codes of the respective numbers corresponding to the plurality of digits recognized by the character recognition unit 12 from the character recognition unit 12 and stores them in the memory 13a.

The character display section 14 is a display device such as an LCD (Liquid Crystal Display) and displays characters and the like on the screen in accordance with an instruction from the control section 13. [ The character display unit 14 displays a character string recognized by the character recognition unit 12, for example.

The user operation unit 15 is made up of various keys, and inputs an event such as a cursor movement by key operation, and notifies the control unit 13 that an event has been input.

The functions of the control unit 13 and the character recognition unit 12 may be realized by a dedicated hardware circuit or by software control by a CPU. An input / output interface (not shown) such as a USB may be connected to the control unit 13 to transmit / receive data to / from an external device.

2 is a diagram showing an example of the external appearance of the character input device 1. As shown in Fig.

A character display section 14, a handwriting input section 11, and a user operating section 15 are provided on the front surface of the housing of the character input device 1, for example. In the character display section 14, the inputted character string is displayed. The handwriting input section 11 is provided with a character entry area 11a capable of handwriting input by a stylus pen or the like. It is also possible to write a plurality of digits or the like in the character entry area 11a as described above. Here, " 12 " is written by handwriting.

The user operation unit 15 has a deletion key 15a, a conversion key 15b, a correction key 15c, a left key 15d, a right key 15e and a confirmation key 15f. The user operation unit 15 may also have other keys, such as full-width / half-width keys, by switching the screen of the portion where these various keys are displayed.

Next, the operation of the character input device 1 will be described.

Initially, the movement of the cursor and focus by the character input device 1 will be described. Fig. 3 is a flowchart showing an example of a procedure for moving the cursor and the focus of the character input device 1. Fig. The character input program for performing this operation is stored in the ROM in the character input device 1 and is executed by the CPU in the character input device 1. [

First, the control unit 13 determines whether or not a handwriting is input by the handwriting input unit 11 (step S1). For example, as shown in Fig. 2, a digit number " 12 " of plural digits by handwriting is input into the character entry area 11a. If the handwriting is not input, the character input device 1 proceeds to the process of step S5.

On the other hand, if there is a handwriting input by the handwriting input unit 11, the character recognition unit 12 recognizes the character corresponding to the handwriting input (step S2). At this time, the character recognition unit 12 acquires the character code registered in the database 12b using the handwriting coordinate pattern, and stores it in the memory 12a. Also, even when the recognized handwriting indicates a plurality of digits, the character recognition unit 12 also acquires a character code corresponding to the digits of a plurality of digits. However, a special character code is used for a multiple digit number.

The control unit 13 receives the character code recognized from the character recognition unit 12 and stores it in the memory 13a in the control unit 13 (step S3). When the recognized character is a plurality of digits (strings), the character codes of the respective numbers corresponding to the digits of the plural digits are stored in the memory 13a. In this case, the control unit 13 determines that there are a plurality of digits in terms of special codes, and converts them into a plurality of normal (individual) character codes from one special code. That is, in the memory 13a, character codes of individual numbers are stored. By repeating this operation, an input character string into which a plurality of characters are inputted is stored in the memory 13a.

The control unit 13 sets a flag for the input character string stored in the memory 13a in the control unit 13 (step S4). Further, the control unit 13 determines that the special code is a multiple digit number and sets a flag.

4 is a diagram showing an example of an input character string and a flag stored in the memory 13a. Here, in the memory 13a, the input string "12 o'clock tomorrow" and the value of the flag corresponding to each character are stored. Specifically, the flag " 0 "is set to the flags of the letters " bright ", " date ", " On the other hand, flags other than the value "0" are set in the flags of the characters "1" and "2", and the value "2" is set here. This numerical value corresponds to the number of characters of the input character string, and it indicates the amount of movement when the focus is moved or the like as will be described later.

In the above description, it is assumed that the value of the flag is "2" assuming that "12" is written in one column (one character write area 11a in FIG. 2) Quot; and " 2 ", respectively, the value of the flag becomes "0 ".

A value equal to or larger than the value "3" may be set in the flag. For example, when "123" and three numbers are described in one column, the value of the flag is "3".

The character display unit 14 displays the inputted character in accordance with an instruction from the control unit 13 (step S5).

Thereafter, the control unit 13 determines whether or not the left key 15d among the various keys of the user operation unit 15 is pressed down (step S6). When the left key 15d is not pressed down, the character input device 1 returns to the process of step S1.

On the other hand, when the left key 15d is pressed down, the control unit 13 discriminates the value of the flag stored in the memory 13a (step S7). If the value of the flag is "0 ", the control unit 13 moves one cursor to the character string displayed on the character display unit 14 (step S8), and adjusts focus for one character (step S9). Thereafter, the character input device 1 returns to the process of step S5.

If the value of the flag is other than "0", for example, "2" in step S7, the control unit 13 moves the cursor by the value of the flag (step S10) and focuses on the moved part Step S11). Thereafter, the character input device 1 returns to the process of step S5.

5 is a diagram showing an example of movement of a cursor and a focus. Before the left key 15d is depressed, the cursor and the focus were at the position of the character " at 12 o'clock tomorrow ", but when the left key 15d is depressed, And moves to the position of the character string " 12 " Further, when the left key 15d is pressed down, the cursor and the focus move to one position of the character " ". Here, the cursor is represented by a rectangular frame, and the focus is indicated by an inverted display within the frame.

As described above, the memory 13a serving as the storage unit may store flags based on the number of characters in correspondence with each character of a character string composed of a plurality of characters recognized by the character recognition unit 12. [ The control unit 13 may control the display of this character string or the editing of the character string as a single character based on the flag stored in the memory 13a. Thus, when the cursor and the focus are moved, the cursor is moved to the number "12" having the same number of characters as the number "12" of the plural digits written by the user in the character entry area 11a, No incongruity occurs.

In the case of deleting a character, similarly, the number "12" at which the cursor is located can be deleted as one character at a time by similarly pressing down the delete key 15a.

Next, display and re-creation of recognition candidates will be described.

6 is a flowchart showing an example of display and re-creation of recognition candidates. The character input program for performing this operation is stored in the ROM in the character input device 1 and is executed by the CPU in the character input device 1. [

As shown in Fig. 3, the control unit 13 determines whether or not a handwriting is input by the handwriting input unit 11 (step S21). If the handwriting is not input, the character input device 1 proceeds to the process of step S25.

On the other hand, if there is an input of handwriting by the handwriting input unit 11, the character recognition unit 12 recognizes the character corresponding to the input handwriting (step S22).

The control unit 13 receives the character code recognized from the character recognition unit 12 and stores it in the memory 13a in the control unit 13 (step S23). Here, the operation when a character string such as a plurality of digits is inputted is the same as that in Fig. 3 described above.

The control unit 13 sets the arrangement number for the input character string stored in the memory 13a in the control unit 13 (step S24). Here, the arrangement number indicates the position where the recognized character is arranged at the time of display or editing. The information of the array number is stored in the memory 13a (storage section). In addition, a plurality of characters having the same arrangement number are treated as one character. That is, the number of characters having the same arrangement number is equal to the number of characters of the inputted string.

7 is a diagram showing an example of a correspondence relationship between an input character and a candidate character that are recognized by the arrangement number. For example, in the arrangement number (1), the candidate characters "bright" and "red" of the input character "bright" are held and in the arrangement number (4), the candidate characters " 12 ", " 72 "

The character display section 14 displays the inputted character in accordance with the instruction of the control section 13 (step S25). Thereafter, the control unit 13 waits until the candidate display operation is performed by the user through the user operation unit 15 or the like (step S26). This candidate display operation is performed by moving the focus position a (see FIG. 7) by the depression of the left key 15d or the right key 15e and moving the position of the handwriting input section 11 The candidate character group is displayed and the focus is set on the candidate character. 8 is a diagram showing an example of a group of candidate characters displayed at the position of the handwriting input section 11. Fig. Here, characters such as "12", "mouth", "b", "72", "to", "R" are displayed as candidate characters of the character "12"

Subsequently, the control unit 13 determines whether or not the character recognition candidate (here, " 12 ") in the focus position a is selected as shown in Fig. 7B (step S27). If not selected, the character input device 1 returns to the process of step S25.

On the other hand, when the recognition candidate is selected, the control unit 13 determines whether the correction key 15c is pressed to rewrite the input character (step S28). When rewriting is performed, the control unit 13 shifts to modification of the character at the focus position a (step S29), and returns to the process of step S21. In Fig. 7 (C), the case where the character " 12 " in the focus position a is rewritten to " 14 " is shown.

On the other hand, if the user does not rewrite in step S28, the control unit 13 determines whether or not the confirmation key 15f is pressed down (step S30). When the determination key 15f is not pressed down, the character input device 1 returns to the process of step S25. On the other hand, when the confirmation key 15f is pressed down, the process returns to step S21.

As described above, the memory 13a serving as the storage unit may store information of the same array number in association with each character of a character string composed of a plurality of characters recognized by the character recognition unit 12. The control unit 13 may control the character string corresponding to the same arrangement number stored in the memory 13a as one character when displaying or editing the character string. Thus, even in the case of displaying the recognition candidate (control of display of a candidate of a character string) or rewriting (rewriting process), it is possible to treat the same as the multiple digit number written in the character entry area 11a There is no incongruity to the user.

According to the character input apparatus of the first embodiment, even when a character string composed of a plurality of characters is input, the number of characters in input, display, and edit can be matched without causing an uncomfortable feeling.

(Second Embodiment)

In the first embodiment, when a plurality of digits are entered in the character entry area, a plurality of positions of the cursor and focus shift are performed, and a plurality of candidate characters are displayed. In the second embodiment, it is possible to display a plurality of candidate characters in addition to the operation of the first embodiment, and to perform one character at a time of cursor / focus movement.

Fig. 9 is a block diagram showing a configuration example of the character input device 1A according to the second embodiment of the present invention. Since the character input device 1A has almost the same configuration as the character input device 1 in the first embodiment, the same constituent elements as those of the first embodiment are denoted by the same reference numerals, , The different components will be described here.

In the character input device 1A, a selection control unit 23 is provided. The selection control unit 23 has a control unit 13 that performs the same control (first control) as that of the first embodiment and a control unit 13A that performs control (second control) . This switching operation can be performed by the user, for example, by a key operation of the user operation unit 15. [ The selection control section 23 may be constituted by, for example, a software switch or a hardware switch.

The control section 13A is provided with a memory 13Aa, a focus / cursor position control section 13Ab and a character recognition control section 13Ac in the same manner as the control section 13. [

The control unit 13A deletes the handwriting and candidate characters of the plurality of digits stored in the memory 12a of the character recognition unit 12 after the candidate characters of a plurality of digits are confirmed, The handwriting of one character is re-entered into the memory 12a to recognize the character.

10 is a flowchart showing an example of the display of the recognition candidates and the movement sequence of the cursor and the focus. The character input program for performing this operation is stored in the ROM in the character input device 1A and is executed by the CPU in the character input device 1A. In Fig. 10, it is assumed that the selection control section 23 is selected to perform the second control.

First, the control section 13A determines whether or not the handwriting input section 11 has input a handwriting (step S31). If the handwriting is not input, the character input device 1A proceeds to the process of step S35.

On the other hand, if there is an input of handwriting by the handwriting input unit 11, the character recognition unit 12 recognizes the character corresponding to the input handwriting (step S32). At this time, when the input character is a plurality of digits, the handwriting and candidate characters of the plurality of digits are stored in the memory 12a.

The control section 13A receives the character code recognized from the character recognition section 12 and stores it in the memory 13Aa in the control section 13A (step S33). At this time, when the recognized character is a number of a plurality of digits, the character code received from the character recognizing section 12 is an individual character code corresponding to a plurality of digits, as in the first embodiment. The control section 13A stores this character code in the memory 13Aa.

In the case of a character string of a plurality of digits or the like, the control section 13A performs an operation of correcting the recognized character (step S34). Here, the control unit 13A deletes the handwriting and candidate characters of the plurality of digits stored in the memory 12a of the character recognition unit 12, and stores the handwriting of one character, which is stored in the memory 13Aa, (12a) to recognize a character. Thereby, the handwriting and the candidate character of one character are stored in the memory 12a based on the candidate character corresponding to the handwriting of the plural digits.

11 is a diagram showing an example of recognition characters which are corrected by re-inputting the handwriting of the recognized character to the character recognition section 12 after recognizing the character. Quot; 12 " is recognized as a candidate character of plural digits, and " 72 " is recognized as " 12 " and other candidate characters. After these are stored in the memory 12a, the control section 13A performs the following operations. In other words, the control section 13A deletes the handwriting of the plural-digit characters stored in the memory 12a of the character recognition section 12 and instead writes the candidate characters " 1 ", " 2 ", and characters " 7 " and " 2 " to the character recognition section 12 again. As a result, the candidate characters " 1 ", " 2 ", and other candidate characters " 7 " and " 2 " are stored in the memory 12a of the character recognition unit 12 after the plural-

The character display section 14 displays the input character according to the instruction of the control section 13A (step S35).

Thereafter, the control section 13A determines whether or not the left key 15d among the user operation section 15 has been pressed down (step S36). When the left key 15d is not pressed down, the character input device 1A returns to the process of step S31.

On the other hand, when the left key 15d is pressed down, the control unit 13A moves one cursor to the character string displayed on the character display unit 14 (step S37), and focuses one character (step S38 ). Thereafter, the character input device 1A returns to the process of step S35.

12 is a diagram showing an example of movement of a cursor and focus. Before pressing down the left key 15d, the cursor and the focus were at the position of the character " at 12 o'clock tomorrow ", but when the left key 15d is depressed, And moves to the position of the string " 2 " When the left key 15d is pressed down, the cursor and the focus move to the position of the character " 1 ".

As described above, in the second embodiment, the character input device 1A is provided with the selection control section 23 as a control section for switching between the first control and the second control. In the first control, control is performed at the time of display and editing of this character string according to the number of characters of the character string composed of a plurality of characters recognized by the character recognition unit 12. [ In the second control, the control according to the number of characters is not performed at the time of displaying or editing the character string. According to the character input device 1A, when a character string such as a plurality of digits is input, the same operation as that of the first embodiment can be performed. In addition, by switching the control, It is also possible to control the cursor, the focus, and the deletion by one character. Thus, the input operation can be performed in accordance with the user's preference.

The present invention is not limited to the above-described embodiment, but can be applied to any function as long as the function shown in the claims or the function of the present embodiment can be achieved.

For example, in the above embodiment, a two-digit number is used as an example of inputting a plurality of characters, but the present invention is not limited thereto. A character string consisting of a plural number of characters, such as blood type "AB" in alphabet, "ai" in hiragana, "+ -" in symbol, and "30 ° C." in combination of symbol and number.

The above embodiment is also effective in displaying and editing a formal sentence. For example, the character input device recognizes one character " a " from the input handwriting and displays a candidate " a " of a character string composed of a plurality of characters corresponding to the character. Then, the character input device may move or delete the cursor or the focus according to the number of characters of the candidate of the character string.

In this way, the character recognition unit 12 may recognize one character (e.g., " a ") from the handwriting input to the character writing area 11a as the predetermined area. The character display section 14 as the display section may display a character string candidate (e.g., "a") composed of a plurality of characters from one character recognized by the character recognition section 12. The control unit 13 may perform control at the time of display or editing by the candidate character display unit 14 of the character string in accordance with the number of characters of the character string candidates. This simplifies the display and editing of the formal sentence.

The present invention is also applicable to a program in which a character input program for realizing the functions of the above embodiment is supplied to a character input device via a network or various storage media and a computer in the character input device reads and executes the character input program.

The character input device of the above embodiment may be an electronic device having a handwriting input function, or may be mounted on various electronic devices such as a smart phone or a tablet terminal.

While the invention has been described in detail and with reference to specific embodiments thereof, it is evident to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

The present application is based on Japanese Patent Application No. 2011-223202 filed on October 7, 2011, the content of which is incorporated herein by reference.
