Description

  The present invention relates to a handwritten character input device for recognizing handwritten characters and inputting them as a desired character string and a control program therefor.

  Conventionally, in a document processing apparatus, a handwriting input device such as a touch pad is provided in advance or connected to the outside, and a handwritten character input by the handwriting input device is recognized and used as regular character data such as a JIS code. An input system for handwritten characters designed to be input has been put into practical use.

  In such a conventional handwritten character input system, characters recognized for each character of a character string input by handwriting are displayed by arranging the first candidate characters as recognition candidates. For this reason, if the displayed recognition candidate character is not the desired input character, the recognition candidate character is sequentially displayed for each character to be corrected, and the desired candidate character is selected and entered, When a series of character strings are input and the first candidate recognized character is not a desired character among the plurality of characters, the correction operation becomes complicated and troublesome.

On the other hand, a series of correct character strings are collected by searching the dictionary data for similar headwords that coincide with the first character strings recognized by handwriting input, displaying them in a list, and selecting and confirming the desired headwords. A correction system for a character recognition result that is input is also conceivable (see, for example, Patent Document 1).
JP 2004-220181 A

  In the conventional correction system for character recognition results, a headword consisting of a desired character string is selected and inputted from a list of headwords similar to the character string in units of a series of character strings recognized by handwriting input. Although it is not necessary to display and correct the recognition candidate characters for each character in sequence, the series of character strings that were initially recognized are recognized as different characters from the desired character, particularly from the first character. If this is the case, the headwords that are searched based on this and displayed in a list also become headwords that are significantly different from the user-desired character strings. Eventually, recognition candidates for each character are sequentially displayed, selected, and corrected. There is a problem that must be done.

  The present invention has been made in view of such problems, and for a series of character strings that have been input by handwriting and recognized, it is not necessary to sequentially display the recognition candidate characters for each character to be corrected and perform a selection operation. It is an object of the present invention to provide a handwritten character input device and its control program that can be easily corrected and input to a desired recognition candidate character.

Character recognition means for recognizing the handwritten character input by the character, candidate character storage means for storing the candidate character recognized for the character each time the handwritten character is recognized by the character recognition means, and the character recognition means The character display control means for sequentially adding and displaying the first candidate character among the candidate characters recognized as the input character as the input character each time the handwritten character is recognized by the character, and the character display control means wherein in correspondence to the displayed input character on the display unit of the input character all candidate characters of the respective input characters stored by the candidate character storage means by Along the side, and candidate character batch display control means for displaying the candidate character of each of the input character from the first candidate character collectively with vertically arranged in the order window, it is collectively displayed by this candidate character collective display control means Among the candidate characters, any candidate character is designated as the first candidate character by sequentially moving the cursor to each input character in order from the first input character according to the user 's cursor operation. The candidate character sequential movement designation means and the characters displayed on the display unit corresponding to the first candidate character designated by the candidate character sequential movement designation means are sequentially corrected to the designated first candidate character. and modifying the display control means for displaying Te, and headword storage means for storing a plurality of headwords, each displayed along the bottom side of the input character by the candidate character batch display control means Of the supplementary characters, the first matching character character string specified by the candidate character sequential movement specifying means and the head word matches the headword stored in the headword storage means among the combinations of candidate characters thereafter. And a candidate character identification display control means for identifying and displaying each candidate character to be displayed .

According to the present invention, among the combinations of the character string of the first candidate character designated by the candidate character sequential movement designation unit and each candidate character thereafter, the candidate that matches the entry word in the entry word storage unit Since characters are selectively displayed by bolding or the like, candidate characters as correct search character strings to be input can be selected and specified individually at a glance from the candidate character batch display window W. In addition, it is possible to provide a handwritten character input device and a control program therefor that can be corrected and input into desired recognition candidate characters .

  FIG. 5 is a diagram showing a dictionary search display state associated with input of a handwritten search character string in accordance with the dictionary search processing of the electronic dictionary device 10.

  Here, the operation in the case of inputting a search character string (keyword) using the handwriting input unit 16 and performing a dictionary search will be mainly described, and the search character string (keyword) is input using the key input unit 14 and the dictionary is searched. Since the operation when searching is the same as the normal operation, the description thereof is omitted.

  When a dictionary designation key (for example, “Wide ○ 苑” key) provided in the key input unit 14 is pressed and inputted in order to designate a desired dictionary as a dictionary search target (step S1 (Yes)). The dictionary data [Wide ○ 苑] corresponding to the “Wide ○ 苑” key input is read from the dictionary data memory 22c and activated, and the search character input area a is displayed as shown in FIG. The provided search character input screen G is displayed on the display unit 17 (step S2).

  At this time, as shown in FIG. 5B, the handwriting input unit 16 has handwritten input display areas 16L and 16R for each left and right characters, a “correction” button 16T, and a “recognition” button 16N. A character input screen MS is displayed (step S3).

  In this handwritten character input screen MS, for example, when it is desired to input “Nuriguri” this time, first, the first handwritten character “Nu” is input to the one handwritten input display area 16L with the touch pen P (step S4 (Yes) )), The character of the locus input by handwriting in the one handwriting input display area 16L is displayed as it is (step S5).

  Subsequently, in the handwritten character input screen MS, when the next handwritten character “ri” is input with the touch pen P into the other (other) handwritten input display area 16R (step S6), the other handwritten input display area The characters of the locus input by handwriting in 16R are displayed as they are (step S7).

  Then, the handwritten character “Nu” that has been input and displayed last time is recognized, the candidate character is stored in the character recognition conversion candidate buffer 22d, and the first candidate character (in this case, “Me”) is searched for. It is displayed in the character input area a (step S8). Then, the headword that matches the head of the search character (string) “Me” displayed in the search character input area a is searched from the dictionary data 22c of the designated [Hiro * 苑] and is entered in the headword list area h1. Are displayed as a list (step S9).

  At this time, the headwords displayed in the list in the headword list area h1 are designated and displayed by the cursor C, and the explanation information corresponding to the headword designated and displayed by the cursor C is specified in the [wide ○苑] is read from the dictionary data 22c and previewed in the explanation information preview area h2.

  Here, when the “recognition” button 16N of the handwritten character input screen MS is touch-input and it is determined that the input of the handwritten character is finished (step S10 (Yes)), the input display is performed in the handwriting input display area 16R. The handwritten character “RI” is recognized as the final handwritten character this time, the candidate character is stored in the character recognition conversion candidate buffer 22d, and the first candidate character (in this case “RI”) is searched for. It is additionally displayed in the character input area a (step S11). Then, the headword that matches the search character string “Meri” displayed in the search character input area “a” is searched from the dictionary data 22c of the designated [Hiro * 苑] and is searched in the headword list area h1. A list is displayed (step S12). Also in this case, as described above, the explanation information corresponding to the entry word designated and displayed by the cursor C is retrieved from the designated [Hiro *] dictionary data 22c and previewed in the explanation information preview area h2. Is done.

  On the other hand, since it is desired to input “Nuriguri” in the handwritten character input this time, the handwritten character input screen is displayed in step S10 after handwritten input in the handwritten input display areas 16L and 16R. If the “recognition” button 16N of the MS is not touch-inputted and the handwritten character “gu” is input and displayed in the other handwriting input display area (in this case, 16L) (step S10). (No) → S6, S7), storing each candidate character in the character recognition conversion candidate buffer 22d by character recognition of the previous second handwritten input character “Ri”, and additional display processing in the search character input area a (Step S8), a search for a headword that matches the search character string “Meri” displayed in the search character input area a and a search for a headword list area h1. Display processing (step S9) is repeated.

  Subsequently, when the handwritten characters “SU” and “RI” are sequentially input to the handwriting input display areas 16R and 16L, the process of step S10 (No) → S6 to S9 is repeated in the same manner. Characters up to the handwritten character “su” are recognized and additionally displayed in the search character input area a, and headwords that match the head of the displayed search character string are searched and displayed in a list.

  After handwriting input up to the final character “RI” to be input this time, the “recognition” button 16N of the handwriting character input screen MS is touch-inputted and it is determined that the input of the handwritten character is finished (step S10 ( Yes)), the last handwritten character “Ri” input and displayed in the handwriting input display area 16L is recognized, and the candidate character is stored in the character recognition conversion candidate buffer 22d, and the first candidate character is included. (In this case, “RI”) is additionally displayed in the search character input area a (step S11). Then, the heading that matches the series of search character strings “Merijisuri” displayed in the search character input area a as shown in FIG. Words are retrieved from the designated [Hiro *] dictionary data 22c and displayed in a list in the headword list area h1 (step S12). In this case as well, as described above, explanation information corresponding to the headword “Meri-ko-mu ...” designated and displayed by the cursor C is retrieved from the dictionary data 22c of the designated [Hiro * 苑] A preview is displayed in the explanation information preview area h2.

  FIG. 6 is a diagram showing an input switching operation of the handwriting input unit 16 when correcting a series of search character strings that are recognized by handwriting input and displayed in the search character input area a in accordance with the dictionary search processing of the electronic dictionary device 10. It is.

  FIG. 7 shows a recognition candidate character collective display that is displayed in correspondence with the search character string as a series of search character strings that have been recognized and input by handwritten characters in the dictionary search process of the electronic dictionary device 10 are corrected. It is a figure which shows the window W. FIG.

  That is, as shown in FIG. 5, a series of search character strings “Merijisuri” displayed in the search character input area a after being recognized in accordance with the handwritten input “Nuriguri” is corrected. Therefore, as shown in FIG. 6A, when the “correction” button 16T of the handwriting input unit 16 is input by pen-touching (step S13 (Yes)), the two handwriting input display areas 16L and 16R have been used so far. 6B, the handwritten character input screen MS is switched to a candidate correction screen KS that displays a cursor movement button 16C, a “confirm” button 16F, and an “end” button 16E, as shown in FIG. (Step S14).

  Then, the recognition candidate characters for each character stored in the character recognition conversion candidate buffer 22d are read with each character recognition of the series of handwritten characters “Nuriguri”, and as shown in FIG. A window (recognition candidate) in which candidate characters of each character are arranged vertically from the first candidate along the lower side of each character of the current search character string “Merijisuri” displayed in the area a. The characters are collectively displayed as a character collective display window W (step S15).

  At this time, a (reverse) cursor C for designating each candidate character in the window W is displayed at the position of the first candidate character of the first input character in the recognition candidate character batch display window W.

  In the flowchart of the dictionary search process (part 2) shown in FIG. 4, “recognition candidate character bolding process” in step SA surrounded by a broken line will be described in a second embodiment to be described later.

  FIG. 8 is a diagram showing a corrected display state of the search character string using the recognition candidate character batch display window W displayed in the dictionary search process of the electronic dictionary device 10.

  FIG. 9 is a diagram showing a specific example in which each candidate character corresponding to the search characters “me” and “ji” to be corrected in the recognition candidate character batch display window W is specified and fixed by the (reverse) cursor C and corrected. It is.

  That is, as shown in FIG. 7, the recognition candidate character batch display window W is displayed along the series of search character strings “Merijisuri” displayed in the search character input area a (step S15) First, in order to correct the first character “Me” of the search character string to “Nu”, the cursor movement button on the candidate correction screen KS of the handwriting input unit 16 displayed as switched as shown in FIG. 6B. By touching 16C, as shown in FIG. 8 and FIG. 9A, the cursor C is moved to “Nu” of the candidate characters of the first character to display it, and the “Confirm” button 16F is touched. Operate (Step S16 (Yes)).

  Then, in response to designation and determination of the first candidate character “Nu” in the recognition candidate character batch display window W, the first character “Me” of the series of search character strings displayed in the search character input area a is displayed. "Is corrected to" Nu "and displayed (step S17).

  Then, the headword that first matches the search character string “Nurijisuri” after the head character correction is searched from the dictionary data 22c of the designated [Hiro * 苑] and displayed in the headword list area h1. (Step S18). In the same manner as described above, explanation information corresponding to the headword “Nuri-shi ...” designated and displayed by the cursor C in the headword list area h1 is searched from the dictionary data 22c of the designated [Hiro * 苑]. The preview is displayed in the explanation information preview area h2.

  At this time, the candidate correction screen KS in the handwriting input unit 16 and the recognition candidate character batch display window W along the search character input area a are continuously displayed, and the candidate correction screen KS of the handwriting input unit 16 is continuously displayed. Is in a standby state for the next touch operation (steps S14 to S16).

  Then, as shown in FIG. 8, in order to correct the third character “ji” of the search character string with the first character corrected to “gu”, the candidate correction of the handwriting input unit 16 is similarly performed as described above. By touching the cursor movement button 16C on the screen KS, as shown in FIG. 9B, the cursor C is moved to “gu” among the third candidate characters, and designated and displayed. The button 16F is touched (step S16 (Yes)).

  Then, as the third candidate character “gu” in the recognition candidate character batch display window W is designated and confirmed, the third character of the series of search character strings displayed in the search character input area a is displayed. “Ji” is corrected to “Gu” and displayed (step S17).

  Then, a headword that matches the head of the search character string “Nurigusuri” with the first and third characters corrected is retrieved from the specified [Hiro * 苑] dictionary data 22c, and is entered in the headword list area h1. A list is displayed (step S18). In the same manner as described above, the explanation information corresponding to the headword “Nuri-Gusuri ...” designated and displayed by the cursor C in the headword list area h1 is obtained from the dictionary data 22c of the designated [Wide ○ 苑]. It is read out and previewed in the explanation information preview area h2 (see FIG. 10).

  FIG. 10 is a diagram showing a display state of the search character input screen G after the search character string correction according to the recognition candidate character batch display window W.

  In a state where the search character string “Meriji-suri” recognized and displayed by the input of the original handwritten characters in accordance with the processing in steps S13 to S18 is corrected to the desired search character string “Nuri-Guri-suri” and displayed. When the “end” button 16E on the candidate correction screen KS of the handwriting input unit 16 is touched (step S19 (Yes)), the recognition candidate character batch display that is displayed along the search character input area a in step S15. The window W is deleted, and the search character input screen G is displayed as shown in FIG.

  Accordingly, the candidate correction screen KS displayed on the handwriting input unit 16 in step S14 is erased, and as shown in FIG. 6A, the handwritten characters including the original handwriting input display areas 16L and 16R. The input screen MS is switched and displayed (step S21).

  Thereafter, the cursor key of the key input unit 14 is operated to move and display the cursor C in the headword list area h1 shown in FIG. 10, and “determine” is selected in a state where a desired headword is selected and displayed. When the key is operated (step S22 (Yes)), the display screen of the explanation information read from the designated dictionary data [Hiro *] 22c corresponding to the designated entry word is displayed on the display unit 17. The display size is displayed in accordance with the entire screen (step S23).

  On the other hand, in the state where the touch operation on the “end” button 16E on the candidate correction screen KS of the handwriting input unit 16 is not determined in step S19, the recognition candidate character batch display window W is erased in step S20, and in step S21. Switching display processing from the candidate correction screen KS of the handwriting input unit 16 to the handwritten character input screen MS is not performed. Even in such a searchable character string correction state, when the cursor C in the headword list area h1 is moved and displayed in the same manner as described above, a desired headword is selected and designated, and the “OK” key is operated. A full-screen display process of explanation information corresponding to the desired headword is executed (steps S22 → S23).

  Thereafter, when the “return” key of the key input unit 14 is operated (step S24 (Yes)), display of the candidate correction screen KS for the handwriting input unit 16 and recognition along the search character input area a The search character string can be corrected according to the display of the candidate character batch display window W (steps S14 to S16).

  Therefore, according to the electronic dictionary device 10 with the handwriting input function of the first embodiment having the above-described configuration, when a desired character is input by handwriting on the handwritten character input screen MS of the handwriting input unit 16, the handwritten character is recognized and its candidate. The character is stored in the character recognition conversion candidate buffer 22d and the first candidate character at that time is displayed in the search character input area a. When the “correction” button 16T of the handwriting input unit 16 is touch-operated to correct the search character displayed on the character recognition display, the handwritten character input screen MS of the handwriting input unit 16 is switched to the candidate correction screen KS. At the same time, the recognition candidate characters corresponding to each character are read from the character recognition conversion candidate buffer 22d along the search characters (strings) displayed by the character recognition and displayed as a window W at a time. A correct recognition candidate character among the recognition candidate characters for each character collectively displayed in the recognition candidate character batch display window W is touched with the cursor movement button 16C displayed on the candidate correction screen KS, and the cursor C is used. When the designated “fixed” button 16F is touched and operated, the candidate characters designated and confirmed on this window W are corrected and displayed in the search character input area a as correct search characters. It is very easy to correct a search character (string) that has been erroneously recognized and displayed.

  According to the electronic dictionary device 10 with the handwriting input function of the first embodiment having the above-described configuration, the search character string displayed in the search character input area a using the batch display window W for the recognition candidate characters is one character. Each time a correction is displayed, the headword that first matches the corrected search character string is searched in the dictionary and updated in the list display area h1, so that a desired headword can be searched quickly while correcting the search character string. Can be displayed.

(Second Embodiment)
In the electronic dictionary device 10 with the handwriting input function of the second embodiment, after step S15 in which the recognition candidate character batch display window W is displayed in the dictionary search process (part 2) shown in FIG.

  FIG. 11 is a flowchart showing a recognition candidate character bolding process executed with the display of the recognition candidate character batch display window W in the dictionary search process of the electronic dictionary device 10 with a handwriting input function according to the second embodiment of the present invention. It is.

  FIG. 12 compares each recognition candidate character batch display window W corresponding to before and after execution of the recognition candidate character bolding process in the dictionary search processing of the electronic dictionary device 10 with a handwriting input function according to the second embodiment. FIG.

  In the handwritten character input screen MS of the handwriting input unit 16, for example, when a desired character string “Himawari” is sequentially handwritten and input, as shown in FIG. While being displayed in the search character input area a on the screen G and headwords matching the search character string “Himaori” at the beginning are searched and displayed in a list (steps S1 to S12), the handwritten input is recognized. When the “correction” button 16T in the handwriting input unit 16 is touched to correct the third character “o” in the search character string to “wa” (step 13 (Yes)), the above FIG. ) → As shown in (B), the handwritten character input screen MS in the handwriting input unit 16 displays a cursor movement button 16C, a “confirm” button 16F, and an “end” button 16E. It is switched to become a candidate correction screen KS (step S14).

  Then, the recognition candidate characters for each character stored in the character recognition conversion candidate buffer 22d with the recognition of each character of the series of handwritten characters “Himawari” are read out, and as shown in FIG. A window (recognition candidate) in which candidate characters of each character are arranged in the vertical direction in order from the first candidate along the lower side of each character of the current search character string “Himaori” displayed in the character input area a. The characters are collectively displayed as a character collective display window W (step S15). Then, the process proceeds to the recognition candidate character bolding process in FIG. 11 for candidate characters for each character displayed in the recognition candidate character batch display window W (step SA).

  That is, when the recognition candidate character bolding process is started, first, the first character “hi” in the series of search character strings “himari” displayed in character recognition is designated (step A1). As shown in FIG. 12B, all the recognition candidate characters “hi”, “mu”, and “b” in the recognition candidate character collective display window W corresponding to the character “hi” are displayed in bold display B1. (Step A2).

  Then, the next second character “ma” in the search character string “Himaori” is designated (step A3), and the characters existing as the first candidate character before the designated character “ma” are designated. Of the character strings “Hima”, “Hiji”, and “Hia” in combination with the character “H”, “Tera”, and “A” corresponding to the designated character “MA”, the dictionary data 22c The candidate characters “ma” and “a” at the head of the combination characters “Hima” and “Hia” that match the headwords stored in are displayed as bolded display B2 (step A4).

  Here, when it is determined that the next character of the search character string “Himaori” is present (Step A5 (Yes)), when the third character “O” is designated (Step A3), this designation is made. The character string “hi” “ma” existing as the first candidate character before the character “o” and the candidate characters “o” “wa” “yu” “re” corresponding to the designated character “o” The combination character “Himao” “Himawa” “Himayu” “Himare” “Himane” in combination with the headword stored in the dictionary data 22c and the first matching character “ The candidate characters “O” and “Wa” at “Himao” and “Himawa” are displayed in bolded display B3 (step A4).

  Thereafter, the same processing is performed for the candidate characters “ri” and “i” corresponding to the fourth character “ri” of the search character string “Himaori” (steps A3 and A4), and there is no next character.
