TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile terminal device having a function of inputting characters via keys smaller than the total number of characters that can be input, a function of converting the input characters to kana-kanji characters, and a method of inputting characters in the mobile terminal device. About.
[0002]
[Prior art]
In a mobile terminal device such as a mobile phone, the area for arranging keys is small, so that only a limited number of keys can be arranged. Therefore, it is necessary to assign a plurality of characters and functions to one key. As a result, many key operations are required to input one character.
[0003]
Taking a mobile phone as a specific example, one line of characters, for example, five characters “A, I, U, E, O” are assigned to one key, and the corresponding character is input according to the number of times the key is pressed. I was This is assigned to each of the numeric keys (numerical key: 123456890) as a line, a line, a line, etc., so that the characters "a" to "n" can be input.
[0004]
For example, for a key to which the line "A, I, U, E, O" is assigned, pressing the key once will result in "A", pressing twice will result in "I", and pressing the key three times will yield "A". U ”, 4 times“ e ”, 5 times“ o ”. Therefore, in order to input various characters, it is necessary to press the key three times on average per character.
[0005]
The above-described input method is generally used in mobile phones that are commercially available at the present time, and is described in, for example, Patent Document 1 below.
[0006]
FIG. 8 is an explanatory diagram showing an operation state in this type of input method. Characters are input from a ten-key (character key group) {circle around (1)} using a thumb shown by a broken line. Switching of the character type (Hiragana, Katakana, alphabet, etc.) is performed by repeatedly pressing the character type key (2). Further, switching between the insert mode and the overwrite mode is performed by the insert / overwrite key (3).
[0007]

[0008]
[Problems to be solved by the invention]
In a mobile phone using the conventional input method, when correcting a single character that has already been input, place the cursor on the character to be corrected and press the key again from the beginning of the selection candidate until the desired character can be selected. The operation had to be repeated.
[0009]
In this case, if the user notices that he or she was originally trying to enter the part of "he" at the time of inputting "heijitsu terminal", he moved the cursor and then entered the character type key (Fig. 8). It is necessary to return the character type to the hiragana mode by 2)) and further press the key of the line (FIG. 8 (1)) as "ha", "hi" and "fu".
[0010]
The above-mentioned problems are not limited to mobile phones, and various types of PDAs, such as PDAs, having a function of inputting characters via keys smaller than the total number of characters that can be input and a function of converting the input characters to kana-kanji characters. This is a problem common to mobile terminal devices.
[0011]
In addition, in the conventional input method, if the kana-kanji conversion is performed in a state where a character is erroneously input, it can be changed to a hiragana state as one of the conversion candidates, but one character is corrected from there. It could not be reconverted. That is, it is necessary to clear the incorrectly input word and re-enter the correct word character.
[0012]
The present invention has been made to solve the above-described problem, and an object of the present invention is to perform character correction with a small number of key inputs when performing a character input through a key that is smaller than the total number of characters that can be input. It is an object of the present invention to provide a portable terminal device character input method and a portable terminal device that are possible.
[0013]
[Means for Solving the Problems]
That is, the present invention as a means for solving the problem is as described below.
[0014]
FIG. 1 is a principle explanatory view showing the principle configuration of a portable terminal device 100 of the present invention. In FIG. 1, reference numeral 101 denotes control means for controlling each unit of the portable terminal device 100; 110, input means for inputting characters; and 120, key input detection for detecting a key input of the input means 110 and generating a key code. Means 130 is a display means for displaying the input characters or converted characters, and 140 is a storage means for storing the key input of the input means 110.
[0015]
The input unit 110 is used for selecting a cursor key 113 for arbitrarily moving a cursor on the display unit, a character key group 114 in which character consonants are assigned to numeric keys, and a character type (Hiragana, Katakana, alphanumeric). , A character switching key 116 for selecting a vowel of a character in the forward and reverse directions, and an insert / overwrite key 117 for switching between an insert mode and an overwrite mode.
[0016]
The character switching key 116 is preferably composed of a rotary encoder, a dial, a seesaw switch, and the like, and is desirably configured to be selectable in the forward and reverse directions. Further, it is desirable that the character type key 115 is also configured in the same manner.
[0017]
(1) Here, the portable terminal device 100 of the present invention performs input by selecting a character type with a character type key 115 and selecting a vowel and a consonant of a character with a character key group 114 and a character switching key 116. And a function of inputting characters via keys smaller than the total number of possible characters.
[0018]
Further, under the control of the control means 101, the attribute (character type, character consonant, character vowel) for each character input from the input means 110 is stored in the storage means 140 until the time of determination.
[0019]
Further, when correcting a character input from the input unit 110, the control unit 101 determines the character to be corrected based on the attribute of the character (character type, character consonant, character vowel) stored in the storage unit 140. Then, at least one of the character type, consonant, and vowel is controlled to be corrected relative to the reference.
[0020]
In the conventional input method, when correcting a single character that has already been input, move the cursor to the character to be corrected by using the cursor key 113, select a character type, and then select again until the target character can be selected. The key push had to be repeated from the beginning of the candidate.
[0021]
In this case, if you notice that you were originally trying to enter the first part of the "he" as "fu" when you entered "heijitsu terminal", according to the conventional correction method, After moving to the part, it was necessary to return the character type from the katakana mode to the hiragana mode with the character type key, and further, to press the key of the line with "ha", "hi" and "fu".
[0022]
The inventor of the present invention has conducted intensive research on the occurrence and correction of such errors, and found that characters near the target character (consonants are matched, vowels are shifted back and forth) are erroneously input. I found that it often happens. Therefore, it has been found that re-selection from the beginning of the selection candidates as in the related art is a useless operation.
[0023]
Therefore, according to the present invention, attributes (character types (hiragana, katakana, alphanumeric characters, etc.)), character consonants (a, ka, sa, ta, na, ha, ma, ya, la, wa), characters The vowels (A, I, U, E, O) are stored in the storage means 140 until finalized.
[0024]
When the input character is corrected under the control of the control means 101, the control means 101 determines the attribute of the character (character type, character consonant, character vowel) stored in the storage means 140 for the character to be corrected. ) Is controlled so that at least one of a character type, a consonant, and a vowel is corrected relative to the reference.
[0025]
In other words, when the cursor on the display unit 130 is returned from the end of the “Hijitsu Terminal” to the head “He” by operating the cursor key 113 by the user, the control unit 101 causes the character attribute (character type (character type) Based on the hiragana, the letter consonant (wa), and the letter vowel (e)), control is performed so as to accept a relative correction from the reference (he).
[0026]
Therefore, when the character switching key 116 is operated by one click on the “−” side (reverse direction side) by the operator, the control unit 101 that has received the “−” one-click data from the key input detection unit 120 sets “ Is returned to "F", and "F" is also displayed on the display means 130. After that, if the operator performs an operation for converting kana to kanji, the control means 101 converts "Fujitsu terminal" to "Fujitsu terminal" and a kanji sentence.
[0027]
According to the correction of such an error, the consonant is matched, and the operation of selecting the character type becomes unnecessary for erroneous input of a character in the vicinity of the target character such as a vowel being shifted back and forth. The number of key operations is reduced as compared with the operation from the first character of "hi" and "fu" and their consonants, and useless operations are drastically reduced. As a result, quick correction can be performed in character input.
[0028]
As a result, it is possible to realize a portable terminal device character input method and a portable terminal device that can perform character correction with a small number of keys when performing character input via keys smaller than the total number of characters that can be input.
[0029]
(2) The portable terminal device 100 of the present invention has a function of selecting a character type with the character type key 115 and a vowel and a consonant of a character with the character switching key 116 and the character key group 114, thereby providing kana kanji. It is configured to have a function of inputting characters via keys less than the total number of characters that can be input before conversion, and a function of converting the input characters into kana-kanji characters.
[0030]
Further, under the control of the control unit 101, the storage unit 140 has a function of storing the attributes (character type, character consonant, and character vowel) of each character input from the input unit 110 until the time of finalization.
[0031]
Under the control of the control means 101, the storage means 140 has a function of storing the character string before the kana-kanji conversion in the kana-kanji conversion execution unit even after the kana-kanji conversion. Further, under the control of the control means 101, when the character string included in the returned character string is corrected after returning to the character string before the kana-kanji conversion after the kana-kanji conversion, the character to be corrected is stored. It has a function of correcting at least one of a character type, a consonant, and a vowel based on the attribute of the character.
[0032]
In the conventional input method, if Kana-Kanji conversion is performed while characters are erroneously input, it can be changed to Hiragana as one of the conversion candidates, but one character is corrected from there and re-converted. I couldn't do that. That is, it is necessary to clear the incorrectly input word and re-enter the correct word character.
[0033]
In this case, when "Ichireibesu" is input and Kana-Kanji conversion is performed and "One example base" is displayed, the part of "Re" of the third input character is originally input as "Ru". According to the conventional correction method, after moving the cursor to the beginning of the word of "example", the character of "example" is cleared (deleted) and a new "ichirui" After inputting, it was necessary to perform kana-kanji conversion to obtain "first base".
[0034]
Therefore, in the present invention, under the control of the control means 101, the attributes (character types (hiragana, katakana, alphanumeric characters, etc.)) and character consonants (a, ka, sa, ta, na, ma, The character vowels (a, i, u, e, o)) and the character string before the kana-kanji conversion (the kana-kanji conversion execution unit) are stored in the storage means 140 after the kana-kanji conversion. Keep it.
[0035]
Then, after performing the kana-kanji conversion, the cursor on the display means 130 is returned to the "1" portion at the beginning of the "example", and the user performs a predetermined key operation (for example, pressing a character type key). When there is, the control means 101 first returns "one example" after the kana-kanji conversion to "ichirei" before the kana-kanji conversion.
[0036]
Further, when the cursor is moved to the “re” portion by the operation of the cursor key 113 by the operator, the control means 101 causes the character attributes (character type (hiragana), character consonant (ra), character vowel (e)). Is controlled so as to accept a relative correction from the reference.
[0037]
Therefore, when the character switching key 116 is operated by one click to the “−” side by the operator, the control unit 101 receiving the data of “−” one click from the key input detection unit 120 changes the “re” to “re”. "Is displayed on the display means 130. After that, if there is an operation of kana-kanji conversion from the operator, the control means 101 converts "ichirui" to "first base" and a kanji sentence.
[0038]
According to the correction of such an error, even after executing the kana-kanji conversion, the operation of selecting the character type is not required for the erroneous input of a character in the vicinity of the target character. The number of key operations is reduced as compared with the operation from the first character of the consonant, and the useless operation is drastically reduced. As a result, quick correction can be performed in character input.
[0039]
As a result, it is possible to realize a portable terminal device character input method and a portable terminal device that can perform character correction with a small number of keys when performing character input via keys smaller than the total number of characters that can be input.
[0040]
(3) The above-described portable terminal device character input is preferably used in a portable telephone.
[0041]
(4) It is also preferable that the above-described character input of the portable terminal device is applied to character input in a portable information terminal such as a PDA other than the portable telephone.
[0042]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, with reference to the drawings, an embodiment of a portable terminal device character input method and a portable terminal device according to the present invention will be described in detail. Here, a description will be given using a specific example of the mobile terminal device 100 applied to a mobile phone.
[0043]
FIG. 2 is a principle explanatory diagram showing the principle configuration of the portable terminal device 100 of the present embodiment.
[0044]
In FIG. 2, reference numeral 101 denotes control means for controlling each unit of the portable terminal device 100; 110, input means for inputting characters; and 120, key input detection for detecting a key input of the input means 110 and generating a key code. Means, 130 is display means for displaying input characters or converted characters, 140 is storage means for storing key input of the input means 110, 150 is a wireless circuit unit for transmitting and receiving as a mobile phone, 160 is a microphone for transmitting, 170 is a speaker for receiving, and 180 is an antenna for transmitting and receiving radio waves.
[0045]
The input means 110 includes a power key 111 for turning on / off the power, a call key 112 for making a call, a cursor key 113 for arbitrarily moving a cursor on the display means, and a consonant of a character assigned to a numeric keypad. Character key group 114, a character type key 115 for selecting a character type (Hiragana / Katakana / alphanumeric characters), a character switching key 116 capable of selecting a vowel of a character in a forward / reverse direction, an insert mode and an overwrite mode. And an insert / overwrite key 117 for performing the switching.
[0046]
The character type key 115 is preferably composed of a rotary encoder, a dial, a seesaw switch, and the like, as shown in FIG. As a result, selection of character types such as hiragana, katakana, and alphanumeric characters can be executed with a small number of operations.
[0047]
In this case, for example, by repeating the selection in the forward direction, the selection can be repeatedly performed as in hiragana, katakana, alphanumeric, hiragana, katakana,. In this case, for example, by repeating the selection in the reverse direction, the selection can be repeatedly performed in the reverse direction, such as hiragana, alphanumeric characters, katakana, hiragana, alphanumeric characters, and so on.
[0048]
The character switching key 116 is composed of a rotary encoder, a dial, a seesaw switch, etc., as shown in FIG. 3 (4), and is configured to be selectable in the forward / reverse (+/-) direction. Is desirable.
[0049]
Thus, by repeating the operation in the forward direction (+ direction), the vowel part for each character consonant can be repeatedly selected as a, i, u, e, a, a, i,. Similarly, by repeating the operation in the reverse direction (−direction), the vowel part for each character consonant is repeatedly selected as a, a, e, a, a, a, a, a,. It is also possible.
[0050]
FIG. 3 is an external configuration diagram showing an example of the arrangement of each key. The character type key 115 shows an example in which the character type key 115 is arranged on the side surface. When operating with the right hand, the character type can be selected with the thumb. is there. Also, the character switching key 116 is shown as an example arranged on the back, and when operated with the right hand, it can be operated with an index finger or the like.
[0051]
The arrangement of the character type key 115 and the character switching key 116, the type and shape of the key switch to be used, the state of the operating hand, and the like are not limited to the specific example of FIG. For example, each key may be a touch panel configured with a liquid crystal display screen instead of a mechanical key.
[0052]
The relationship between the key layout of the character key group 114 (the numeric keypad {circle around (1)} in FIG. 3) in FIG. 2 and the table contents of the input characters by selecting the character type (Hiragana / Katakana / alphanumeric) is as shown in FIG. Has become. It is assumed that the contents of this table are stored in either the control unit 101 or the storage unit 140.
[0053]
That is, in the portable terminal device 100 of the present embodiment, the character type (any of hiragana, katakana, and alphanumeric characters) selected by the character type key 115 is selected by the character key group 114 under the control of the control means 101. Character consonants (a, ka, sa, ta, na, ha, ma, ya, la, wa) and character vowels (a, i, u, e, o) selected by the character switching key 116 are input. It is configured to select a power character (see FIGS. 4B and 4C).
[0054]
In the portable terminal device 100 according to the present embodiment, in the case of the alphanumeric mode, there is no consonant / vowel, so the character range (A to A) selected by the character key group 114 is controlled by the control unit 101. c, D to f, G to i, etc.) are selected with the character switching key 116 to determine the character to be input (see FIG. 4D).
[0055]
FIG. 5 shows an example of a case where a character input for a certain word is executed. The character input control of the control means 101 causes the current according to the character type (one of hiragana, katakana, and alphanumeric characters) selected by the character type key 115. The character type, the current character key based on the character consonant selected by the character key group 114, and the current character string based on the character vowel selected by the character switching key 116 are temporarily stored in the table of the storage unit 140. The character display control of the control means 101 displays the character determined by the current character type, current character key, and current character string stored in the table on the display means 130.
[0056]
<Explanation of Operation of First Embodiment>
Here, the operation of the embodiment of the portable terminal device character input method and the portable terminal device according to the first embodiment will be described with reference to the flowchart of FIG. Note that the flowchart of FIG. 6 is a flowchart relating to control of character input, and corresponds to a subroutine called at regular intervals in various types of overall control.
[0057]
The control means 101 of the portable terminal device 100 stores initial values in the current character mode, current column number, and insert / overwrite mode of the storage means 140 prior to character input (S1 in FIG. 6).
[0058]
Here, when the insert / overwrite key 117 of the input unit 110 is pressed (“insert / overwrite” in FIG. 6S2), the key input detection unit 120 detects a key input (S3 in FIG. 6) and controls the detection result. To the means 101.
[0059]
Here, the control unit 101 switches from the insert mode to the overwrite mode or from the overwrite mode to the insert mode in accordance with the currently executed insert / overwrite mode and the input of the insert / overwrite key. (S4 in FIG. 6).
[0060]
When the cursor key 113 of the input means 110 is pressed ("cursor" in S2 in FIG. 6), the key input detection means 120 detects a key input (direction and the number of inputs) (S5 in FIG. 6) and controls the detection result. To 101. Here, the control means 101 changes the position of the cursor currently displayed according to the input of the cursor key 113 (S6 in FIG. 6).
[0061]
When the character type key 115 of the input unit 110 is pressed ("character type" in S2 of FIG. 6), the key input detection unit 120 detects a key input (S7 in FIG. 6), and transmits the detection result to the control unit 101. Here, the control unit 101 reflects the current character mode (character type currently being executed (hiragana, katakana, alphanumeric characters)) according to the input direction and the number of inputs of the character type key 115 (S8 in FIG. 6).
[0062]
When any of the character key groups 114 is pressed ("character key" in FIG. 6S2), the key input detecting means 120 detects a key input (FIG. 6S9). Here, the control means 101 reflects the current character key number (the key number corresponding to the consonant of the character) corresponding to the input key of the character key group 114 (S10 in FIG. 6).
[0063]
When the character switching key 116 of the input unit 110 is pressed (“character switching” in S2 in FIG. 6), the key input detection unit 120 detects a key input (S11 in FIG. 6) and transmits the detection result to the control unit 101. . Here, the control means 101 reflects the increase or decrease corresponding to the input direction and the number of inputs of the character switching key 116 by adding or subtracting it to or from the current column number (the number corresponding to the vowel of the character) (S12 in FIG. 6). ).
[0064]
Here, when the key input detection unit 120 detects that the character key group 114 is performing input processing (Y in S13 in FIG. 6), the character input position on the display unit 130 is changed by the character display control of the control unit 101. After moving one character (S14 in FIG. 6), the current current character mode, current character key number, and current column number are stored in the input history table of the storage means 140 (S15 in FIG. 6).
[0065]
Here, when the character key group 114 is not in the input process (N in S13 in FIG. 6), the current column number is initialized by the character display control of the control means 101 in the overwrite mode (“overwrite mode” in S16 in FIG. 6). The value is returned to 1 (S17 in FIG. 6). On the other hand, if the mode is the insertion mode ("overwrite mode" in S16 in FIG. 6), the current character type and the current column number of the character at the current cursor position are read from the input history table in the storage means 140 (S18 in FIG. 6).
[0066]
Then, the control unit 101 reads the key map table and the character mode list from the storage unit 140. Further, input character candidates are searched from the current character mode, the current character key number, and the current column number (S19 in FIG. 6). Further, the control means 101 displays the searched input character candidates at the cursor position of the display means 130 (S20 in FIG. 6).
[0067]
Here, a specific example will be given to compare and explain the embodiment and the conventional example. Here, if you are trying to enter "Fujitsu Terminal" and realize that you originally entered "Fu" at the beginning of "He" at the time you entered "Fujitsu Terminal" Suppose.
[0068]
According to the conventional correction method,
Move the cursor from the end to the beginning (operation (1));
-Use the character type key to change the character type from Katakana mode to alphanumeric mode (operation (2)).
-Use the character type key to change the character type from the alphanumeric mode to the hiragana mode (operation (3)).
・ Press the character key of the line “ha” → “hi” (operation ▲ 4 ▼),
・ Press the character key on the line “Hi” → “Fu” (operation ▲ 5 ▼),
・ Press the character key on the line “F” → “He” (Operation ▲ 6 ▼),
As a result, a total of 6 operations were required.
[0069]
Therefore, in this embodiment, the attributes (character types (hiragana, katakana, alphanumeric characters, etc.)) and character consonants (a, ka, sa, ta, na, ha, ma, ya, la, wa ) And character vowels (A, I, U, E, O)) are stored in the storage means 140 until conversion or input determination.
[0070]
When the input character is corrected under the control of the control means 101, the control means 101 determines the attribute of the character (character type, character consonant, character vowel) stored in the storage means 140 for the character to be corrected. ) Is controlled so that the character type, character key number (consonant), and character string number (vowel) are corrected relative to the reference.
[0071]
That is, in the present embodiment,
Move the cursor from the end to the beginning "to" (operation (1));
Under the control of the control means 101, the character type at the input position returns to the original hiragana (no operation required),
Under the control of the control means 101, "he" (character key number: character string number: 4) at the input position becomes a reference position for correction (operation is unnecessary).
Operate the character switching key 116 in one direction in the “−” → “F” (operation (2));
As described above, a total of two steps are required.
[0072]
Therefore, according to the present embodiment, when the character switching key 116 is operated by one click to the “−” side (reverse direction side) by the operator, the key input detection unit 120 outputs “−” one-click data. The control unit 101 that has received the information returns “he” to “fu” and displays “fu” on the display unit 130. After that, if the operator performs an operation for converting kana to kanji, the control means 101 converts "Fujitsu terminal" to "Fujitsu terminal" and a kanji sentence.
[0073]
According to the correction of such an error, the consonant is matched, and the operation of selecting the character type is not required for erroneous input of a character near the target character such as a vowel being shifted back and forth. This eliminates the need for selection, and further reduces the number of key operations compared to operations from the first character of "ha", "hi", "fu" and the consonants, and drastically reduces unnecessary operations. As a result, quick correction can be performed in character input.
[0074]
As a result, it is possible to realize a portable terminal device character input method and a portable terminal device that can perform character correction with a small number of keys when performing character input via keys smaller than the total number of characters that can be input.
[0075]
In the first embodiment, the character vowel portion is corrected by the character switching key 116. However, the correction of the hiragana to the katakana by the character type key, the correction of the character consonant portion by the character key group 114, Alternatively, even with a combination of these modifications, the modification can be completed with less input than before.
[0076]
<Explanation of Operation of Second Embodiment>
Next, the operation of the embodiment of the portable terminal device character input method and the portable terminal device according to the second embodiment will be described with reference to the explanatory diagram of FIG.
[0077]
In this embodiment, the mobile terminal device 100 controls the character type key 115 to select the character type under the control of the control unit 101, and selects the vowel and consonant of the character using the character switching key 116 and the character key group 114. By doing so, in addition to the function of inputting characters via keys less than the total number of characters that can be input before the kana-kanji conversion, a function of converting the input characters into kana-kanji is provided.
[0078]
Further, under the control of the control unit 101, the storage unit 140 has a function of storing the attributes (character type, character consonant, and character vowel) of each character input from the input unit 110 until the time of finalization. Under the control of the control means 101, the storage means 140 has a function of storing the character string before the kana-kanji conversion in the kana-kanji conversion execution unit even after the kana-kanji conversion. Further, under the control of the control means 101, when the character string included in the returned character string is corrected after returning to the character string before the kana-kanji conversion after the kana-kanji conversion, the character to be corrected is stored. It has a function of correcting at least one of a character type, a consonant, and a vowel based on the attribute of the character.
[0079]
Here, FIG. 7 shows a display example of the display means 130 of the mobile terminal device 100. In this case, when "Ichireibesu" is input and Kana-Kanji conversion is performed and "One example base" is displayed, the part of "Re" of the third input character is originally input as "Ru". The description will be made on the assumption that the user has noticed (FIG. 7A). At this point, the cursor is displayed after "S" in a state of waiting for input of the next character.
[0080]
According to the conventional correction method, after moving the cursor to the beginning of the word of “example”, two characters of “example” are cleared (deleted), a new “ichirui” is input, and then the kana kanji is input. The conversion had to be performed to make it "first base."
[0081]
On the other hand, in the portable terminal device 100 according to this embodiment, the attributes (character type (hiragana, katakana, alphanumeric characters, etc.), character key number (character consonant), The character string number (character vowel) and the character string before the kana-kanji conversion (the kana-kanji conversion execution unit) are stored in the storage unit 140 after the kana-kanji conversion.
[0082]
Then, after the kana-kanji conversion is performed, the cursor on the display means 130 is returned to the head "one" of the "example" by operating the cursor key 113 (FIG. 7B). When a given key operation (for example, pressing a character type key) is performed, the control means 101 first returns "one example" after the kana-kanji conversion to "ichirei" before the kana-kanji conversion (FIG. 7 ( c)).
[0083]
Here, the control unit 101 refers to the storage unit 140 to call the character string before the kana-kanji conversion (the kana-kanji conversion execution unit), and displays it on the display unit 130 as an unconverted hiragana. . In other words, the state is different from the conventional conversion / fixation to hiragana by the kana-kanji conversion.
[0084]
Further, when the cursor is moved to the “re” portion by the operation of the cursor key 113 by the operator (FIG. 7D), the control unit 101 causes the character attributes (character type (hiragana), character consonant (ra)). , A character vowel (e)) as a reference, and controls to accept a relative correction from the reference (re).
[0085]
Here, when the character switching key 116 is operated by one click to the “−” side by the operator, the control unit 101 that has received the data of “−” one click from the key input detection unit 120 changes “re” to “ And the display means 130 also displays "R" (FIG. 7 (e)).
[0086]
After that, if an operation of kana-kanji conversion is performed by the operator on the input unit 110, the control unit 101 converts the “Ichirui” portion into “first base” and a kanji sentence, and displays the conversion state on the display unit 130. Is also displayed (FIG. 7F).
[0087]
According to the correction of such an error, even after performing the kana-kanji conversion, the operation of selecting the character type is not required for erroneous input of a character near the target character. Also, even if the converted kanji can be returned to the state before conversion, if the character input is the conventional method, it is necessary to operate from the first character of "ra""ri""ru" and its consonant However, in the present embodiment, the number of key operations is reduced as compared with such a case, and unnecessary operations are drastically reduced. As a result, quick correction can be performed in character input.
[0088]
As a result, it is possible to realize a portable terminal device character input method and a portable terminal device that can perform character correction with a small number of keys when performing character input via keys smaller than the total number of characters that can be input.
[0089]
In the second embodiment, the character vowel portion is corrected by the character switching key 116. However, the correction from the hiragana to the katakana by the character type key, the correction of the character consonant portion by the character key group 114, Alternatively, even with a combination of these modifications, the modification can be completed with less input than before.
[0090]
