Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text input technique,
In particular, the present invention relates to a text input device and method for estimating a word in the middle of input in a word processor, a computer or the like and displaying the word without waiting for completion of input.

[0002]

2. Description of the Related Art Generally, in order to estimate and display a word in the middle of inputting a sentence in a text input, a dictionary storing words that are often used in a text is searched, and the end portion of the character code string being input and the dictionary It searches for whether the beginning part of each word matches, and when the matching word can be specified uniquely, it complements and displays the part of the word that has not been input yet.

A conventional text input device will be described below. FIG. 9 is a block diagram of a conventional text input device. In FIG. 9, reference numeral 31 is an input means for sequentially inputting characters. 32
Is a character code storage means for storing the character code. 33
Is a dictionary that stores words that are often used in sentences.
Reference numeral 34 is a dictionary collating means for collating an input character code string with a word registered in the dictionary. A display unit 35 displays characters.

The operation of the text input device configured as described above will be described with reference to FIG. FIG. 10 is a schematic diagram showing an example of a conventional character input procedure. It shows a case where "i", "n", "ta", and "-" are sequentially input from the input means 31.

The operator inputs "i" from the input means 31,
Character code storage means 3 when "n" and "ta" are sequentially input
2 and the dictionary collating means 34 have character codes "a", "n",
In the state in which “TA” is stored and “INTER” is displayed on the display means 35, the operator continues to input means 31.
The case where "-" is input from will be described.

The input means 31 sends the character code "-" to the character code storage means 32. The character code storage means 32 stores the character code "-". The character code storage means 32 sends the character code “−” to the dictionary matching means 34. The dictionary matching means 34 checks how many words in the dictionary 33 begin with "inter". In this example, the dictionary 33 has "inter"
Since the word starting with "" is the only "interchange", the dictionary matching means 34 notifies the character code storage means 32 that the word has been identified and the character code string "interchange". The character code storage means 32 additionally stores the character code string "-change" and sends the character code string "-change" to the display means 35. The display means 35 displays "-change" character by character. Here, the word intended by the operator is not "interchange" but "intern"
Consider if it was. The operator sequentially inputs the backward key four times from the input means 31. The character code of the backward key is 4
It is sent to the character code storage means 32. The character code storage means 32 sequentially notifies the display means 35 to erase "ji", "n", "e", and "chi". The display means 35 sequentially clears "di", "n", "e", and "chi".

Apart from this, there is also the following method for erasing the "change" of the "interchange". Set a revocation key to notify you if your guess is wrong,
When the cancel key is input, the complementary character string "change" is deleted. If there is a character input other than the cancel key, the character is displayed after "Change". When the cancel key is input and the complementary character string "change" is deleted, the character to be input next is stored in the position where "h" of "change" was present.

[0008]

However, in the above-mentioned conventional configuration, when the specified word is not intended by the operator, the complemented portion is deleted by inputting the backward key or the cancel key, and then the operator. I had to correct it to the intended word. For example, in the input example of "Interchange" above, if the word intended by the operator is "Intern", enter the back key four times or enter the cancel key to erase "Change" and enter "N". I have to do it again.

The present invention solves the above-mentioned conventional problems. When the operator overwrites the complemented position,
It is an object of the present invention to provide a text input device and a method thereof that consider that it has been notified that the complementary character string was not intended by the operator, and cancel the correction by reducing the completion of the operator.

It is a further object of the present invention to save the storage area and shorten the time required for collation.

It is a further object of the present invention to prevent annoying display for the operator without displaying an incorrect word even when a word that is not in the dictionary is input and is collated with a word that happens to be in the dictionary.

It is a further object of the present invention to reduce the storage capacity of a text input device having a kana-kanji conversion function and to increase the probability that an operator who is accustomed to kana-kanji conversion will select an intended word.

It is a further object of the present invention to reduce the burden on the operator who creates the dictionary and increase the probability that the word intended by the operator will be selected.

[0014]

In order to achieve this object, a text input device and method of the present invention include a display means for sequentially displaying characters at designated positions, and a character input by inputting characters. Input means for notifying a code and an input position, a dictionary for holding words, a character code input by the input means are sequentially stored, and the end portion of the character code string is collated with the head portion of each word in the dictionary. Whether the word can be identified when there is only one word to be matched and a dictionary matching means for outputting the character code string of the word, and the character code notified from the input means are sequentially stored, A character code storage means for storing the character code of the word output by the dictionary collating means, and notifying the display means of a part or all of the stored character code string and its display position; A character stored in the character code storage means is displayed by the display means at an input position notified from the column, and an overwrite determination means for checking whether or not the character is a character output by the dictionary matching means, The character code storage means is provided with a deleting means for deleting the character code stored in the character code storage means and outputted by the dictionary matching means.

Alternatively, when there is no word that can be collated in the dictionary, the dictionary collating unit is replaced with the dictionary collating unit that clears the character code string stored in the dictionary collating unit.

Alternatively, an input character counting means for counting the number of input characters is provided, and when a word can be uniquely specified, the word intended by the operator is not estimated immediately and continuously until a predetermined number of characters are input. It has a configuration in which the dictionary collating means is replaced with a dictionary collating means for notifying the character code storage means of the word only after the number of characters is input after the word collation is continued.

Alternatively, the above-mentioned dictionary is replaced with a kana-kanji conversion dictionary having kanji notation.

Alternatively, the dictionary is provided with word extracting means for extracting an independent word from the character code string stored in the character code storage means, and word registration means for registering the independent word in the dictionary, in which recently input words are sequentially stored. It has a configuration in which the dictionary is replaced with.

[0019]

With this configuration, when the complementary character string is not intended by the operator, the character intended by the operator is input to the position of the complementary character string on the display means by the input means, and the complementary character is determined by the overwrite determining means. It is determined that a character has been overwritten at the display position of the column, the determination is notified to the deletion means, and the deletion means deletes the complementary character string output by the dictionary matching means stored in the character code storage means, and the character code storage is performed. The display means deletes the complement not intended by the operator by notifying the display means to delete the complementary character string.

【Example】

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a text input device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 is an input means for sequentially inputting characters. A character code storage unit 2 stores a character code. Reference numeral 3 is a dictionary, which stores words often used in sentences. Reference numeral 4 denotes a dictionary collating means, which checks whether or not the end portion of the character code string stored in the dictionary collating means and the beginning portion of each word in the dictionary are collated, and the word can be specified when only one word is collated. And the character code string of the word is output. A display unit 5 displays the characters stored in the character code storage unit. Reference numeral 6 denotes an overwriting determination means, which determines whether or not the character input by the input means overwrites the complemented character. Deletion means 7 deletes the last character string output from the dictionary matching means among the character codes stored in the character code storage means.

The operation of the text input device configured as described above will be described with reference to FIGS. 4, 5 and 6.

FIG. 4 is a schematic diagram showing an example of a sentence input procedure in the embodiment of the present invention. "I" from the input means 1,
It shows a case where "n", "ta", "-", and "de" are sequentially input. From the input means 1, "a", "n", "ta",
"-" Is sequentially input.

The input means 1 sequentially sends the character codes "a", "n", "ta" and "-" to the overwriting determination means 6 and the respective input positions. The overwrite determination means 6 compares the display position of each character stored in the character code storage means 2 with the input position of the character sent from the input means 1 to check whether or not there is the same. Since there is no same input position here, the overwriting determination means 6 determines that these characters are not overwritten input, and then the character codes "a", "n", "ta", and "-" are stored in the character code storage means. Send to 2. The character code storage means 2 stores the character codes "a", "n", "ta", and "-".
The character code storage means 2 stores the character codes “a”, “n”,
“Ta” and “−” are sent to the dictionary matching means 4. The dictionary matching means 4 checks how many words in the dictionary 3 begin with "inter". In this example, the dictionary 3 has only the word "interchange" starting with "inter" in the dictionary 3, so the dictionary matching means 4
Notifies the character code storage means 2 that the word has been identified and the character code string "interchange". The character code storage means 2 sends "-change" to the display means 5 which has not been sent yet. The display means 5 displays "-change" character by character. Here, it is assumed that “interchange” is the word intended by the operator. In that case, the operator is the character following the next input position of "J" of "Interchange",
In this example, "de" may be input.

On the other hand, the operation when the complemented character string is not the character string intended by the operator will be described. FIG. 5 is a schematic diagram showing an example of a sentence input procedure in the case of complementing a word not intended by the operator. Input means 1 as in FIG.
When "i", "n", "ta", and "-" are sequentially input into the dictionary 3, the word to be matched with "inter" is only "interchange" in the dictionary 3, so that the display means 5 again displays "change". Display one character at a time. Here, it is assumed that "intern" is the word intended by the operator. The operator inputs “n” from the input means 1 to the display position of “h” of “interchange” on the display means 5. The input means 1 sends the character code "n" and its input position to the overwrite determination means 6. The overwrite determination means 6 compares the input position of each character stored in the character code storage means 2 with the input position of "n" to check whether or not there is the same. As a result, it can be seen that the input position is the same as the previously complemented “H”. The overwrite determination means 6 sends the character code “n” to the deletion means 7. The deleting means 7 deletes the character code stored in the character code storing means 2 complemented immediately before, and then deletes the character code "n".
And the input position thereof are sent to the character code storage means 2. The character code “n” is stored in the character code storage means 2 at the input position notified from the deletion means. The character code storage means 2 notifies the display means 5 to clear “change” and display “n”. The display means 5 clears "change" and displays "n" at the place where "h" was.

Next, the case where the input character code string and the word registered in the dictionary are not matched will be described with reference to FIG. At the stage of inputting "F", "o", "-", and "ri", there are no more words to be matched in the dictionary 3, but the input is continued. Further, when "n", "la" and "n" are entered, the character code string stored in the dictionary matching means 4 becomes "foreign run", and the last "run" and the "run" at the beginning of the "language" of the dictionary 3 are entered. , The dictionary matching means 4 notifies the character code storage means 2 of the fact that the word can be identified and the character code string “language”, and the character code storage means 2 still sends it to the display means 5. Not send "nuge". The display means 5 displays "nga" one by one.

As described above, according to this embodiment, when the complementary character string is not intended by the operator, the complementary character string is deleted by overwriting and inputting the character intended by the operator. It is possible to perform the input of, and it is possible to reduce the input work of the operator.

The character code string stored in the dictionary collating means at the time of collation is unnecessary and may be cleared.

(Embodiment 2) An embodiment of claim 5 of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram of a text input device according to an embodiment of claim 5 of the present invention. In FIG. 2, reference numeral 11 is an input means for sequentially inputting characters. A character code storage unit 12 stores the character code. Reference numeral 13 is a dictionary, which stores words often used in sentences. Reference numeral 14 is a dictionary collating means for checking whether the end portion of the character code string stored in the dictionary collating means and the beginning portion of each word in the dictionary are collated. Then, when the word can be uniquely identified, the word intended by the operator is not estimated immediately, and the word matching is continued until a predetermined number of characters are input, and only after the number of characters is input, The word is notified to the character code storage means. A display unit 15 displays the characters stored in the character code storage unit. 1
Reference numeral 6 denotes an overwriting determination means, which determines whether or not the character input by the input means is overwritten on the character complemented by the word identified by the dictionary matching means. Reference numeral 17 denotes a deletion means, which is one of the character codes stored in the character code storage means.
The last character string output from the dictionary matching means is deleted. Reference numeral 18 denotes an input character counting means, which counts the number of input characters since the notification from the dictionary matching means. Here, it is assumed that the matching is continued until two more characters are input after the word is uniquely specified.

FIG. 7 is a schematic diagram showing an example of a sentence input procedure in the embodiment of the present invention. When "i", "n", "ta", and "-" are sequentially input from the input means 11, the word to be matched with "inter" is only "interchange" in the dictionary 13, so the input character counting means 18 receives the input characters. Notify to start counting. Then, "chi",
When "e" is input, the input character counting means 18 notifies the dictionary matching means 14 that two characters have been input after the count is started. The dictionary matching means 14 notifies the character code storage means 12 of the fact that the word has been specified and the character code string “interchange”.

On the other hand, the operation when the uniquely specified word is not the word intended by the operator will be described.
FIG. 8 is a schematic view showing an example of a sentence input procedure in the embodiment of the present invention. From the input means 11, "a", "n",
When the characters "ta" and "-" are sequentially input, the word to be matched with "inter" is only "interchange" in the dictionary 13, so the input character counting means 18 is notified to start counting the input characters. Since the number of input characters is 0 at this stage, the dictionary collating means 14 does not send the character code to the character code storing means 12. That is, the character string complement operation is not activated at this point, and the complementary character string is not displayed on the screen. Next, when "n" is input from the input means 11, the dictionary matching means 14 searches the dictionary 13 for a word to be matched with "intern", but since there is no word starting with "intern" in the dictionary 13, the word intended by the operator. Is regarded as not an "interchange", and the character string code for matching held by the dictionary matching means 14 is deleted. At this stage, since the number of input characters is 1 and there is no word in the dictionary 13 that starts with "intern", the dictionary collating means 14 does not send the character code to the character code storing means 12, and the complementary character string is displayed on the screen. Not done. The character code storage means 12 is the display means 1
Send the character code "n" to 5. The display means 15 displays "n" at the display position next to "inter".

As described above, according to the present embodiment, even when a word that is not in the dictionary is input and is collated with a word that happens to be in the dictionary, the number of times of displaying an erroneous word is reduced, and a display annoying to the operator is displayed. Can be avoided.

(Embodiment 3) An embodiment of claim 9 of the present invention will be described below with reference to the drawings.

FIG. 3 is a block diagram of a text input device according to a ninth embodiment of the present invention. In FIG. 3, reference numeral 21 is an input means for sequentially inputting character codes. A character code storage unit 22 stores a character code. Reference numeral 23 is a dictionary, which stores independent words that appear during text input. Reference numeral 24 is a dictionary collating means for checking whether or not the end portion of the character code string stored in the dictionary collating means and the head portion of each word in the dictionary are collated. A display means 25 displays the characters stored in the character code storage means. Reference numeral 26 denotes an overwriting determination means, which determines whether or not the character input by the input means is overwritten by the character complemented by the word identified by the dictionary matching means. Deletion means 27 deletes the last character string output from the dictionary matching means among the character codes stored in the character code storage means. Reference numeral 28 is a word extracting means, which stores a predetermined number of the latest input characters and extracts independent words as words from the stored input characters. Reference numeral 28 denotes a word registration means, which is a word extracted by the word extraction means and which is not registered in the dictionary yet is registered in the dictionary. If no more words can be registered in the dictionary, the word registration means deletes the oldest registered word and then registers a new word.

As described above, according to this embodiment, since the same word is repeatedly input in one sentence in many cases,
By using a dictionary in which recently input words are sequentially stored, it is possible to increase the probability that the word intended by the operator is selected.

Although the Katakana language has been described as an example in each embodiment, it is obvious that the object of the present invention is not limited to the Katakana language.

[0038]

As described above, according to the present invention, when the complementary character string is not intended by the operator, the complementary character string can be deleted by overwriting the complementary character string. It is possible to realize a text input device that can reduce the input work of.

Further, when there is no word that can be collated, a dictionary collating means for clearing the character code string stored in the dictionary collating means is provided, and the character string to be collated is shortened to save the storage area. In addition, the time required for matching can be shortened.

In addition, when the input character counting means is provided and the word is estimated only when a predetermined number of characters are input, the word which is not in the dictionary is input and the word is accidentally collated with the word in the dictionary. However, it is possible to reduce the number of times an erroneous word is displayed, and avoid annoying display for the operator.

Further, by replacing the dictionary with a kana-kanji conversion dictionary, the storage capacity is reduced in a text input device that also has a kana-kanji conversion function, and an operator who is familiar with kana-kanji conversion selects the intended word. The probability of doing can be increased.

Further, the word extracting means and the word registering means are provided, and the recently input words are sequentially stored in the dictionary, thereby reducing the burden on the operator who creates the dictionary and selecting the word intended by the operator. It is possible to increase the probability of being killed.
