Description

  The present invention relates to a mobile communication terminal device, and more particularly to a character conversion method based on key operations.

  2. Description of the Related Art Conventionally, various character conversion methods such as a Kana-Kanji conversion method for converting Kana characters into Kanji and a Roman-Kanji conversion method for converting Roman characters into Kanji have been proposed as key input conversion methods for keyboard key operations.

  The character input mode is used when multiple types of characters such as kana, katakana, romaji, numbers, and kanji correspond to the same key and you want to convert them to characters that do not support the conversion method. Had to switch. For example, when the kana character input mode is set, it is difficult to input English and / or numbers without switching to the alphanumeric character input mode. In other words, if there are two character input modes, the Kana character input mode and the alphanumeric character input mode, if the mode setting is entered incorrectly, the character must be erased and then input again. There was a fault that it was bad.

  Japanese Patent Application Laid-Open No. 6-4517 discloses a Japanese input device that improves operability during character input by making it possible to convert between an alphanumeric character input mode and a kana character input mode.

  However, in a mobile communication terminal device such as a mobile phone, characters that are converted in response to the number of key presses of the same key are supported instead of a character input method based on a single key input. Therefore, in order to simplify key input, not only characters to be simply converted but also a plurality of conversion candidates may be prepared in advance.

  FIG. 7 is a diagram for explaining display of conversion candidates in character input in a conventional mobile communication terminal device.

  FIG. 7A shows a character input screen. For example, it is assumed that a text input screen for editing a so-called mail content is shown. As described above, generally, as a character input method of the mobile communication terminal device, a method of displaying characters based on the number of times the dial key is pressed is employed.

  For example, here, a relationship between dial keys and kana characters, a so-called kana character conversion table will be described with an example.

  The dial key “1” corresponds to the characters “A, I, U, E, O” in the row, and is displayed after being converted into one of the characters based on the number of times the key is pressed. . The dial key “2” corresponds to the characters “ka, ki, k, ke, ko” in the line, and is displayed after being converted into any character based on the number of times the key is pressed. Shall. The dial key “3” corresponds to the characters “S, S, S, S, S, S” in the row, and is displayed after being converted to one of the characters based on the number of times the key is pressed. To do. The dial key “4” corresponds to the characters “Ta, Chi, Tsu, Te and” on the line, and is displayed after being converted into one of the characters based on the number of times the key is pressed. . Similarly, other dial keys are assigned characters on other lines, and are converted into characters assigned based on the number of key presses and displayed. Further, not only 50-character characters but also various set symbols are assigned to predetermined dial keys, converted into symbols assigned based on the number of key presses, and displayed. In the present specification, the characters include symbols.

  FIG. 7B shows, for example, the dial key “1” once, the dial key “2” once, the dial key “3” twice, It is a figure explaining the character display and conversion candidate at the time of pressing "4" of a dial key 3 times.

  As shown in FIG. 7B, the letters “Akasatsu” are displayed according to the letters assigned to each of the dial keys. Note that the determination of each character based on the number of key presses is not determined even if the same dial key is pressed multiple times, but the previous dial key is pressed when another different dial key is pressed. The character based on the number of times shall be determined.

  In this example, full-width Katakana characters “Akashits”, full-width Hiragana characters “Akasatsu”, and half-width Katakana characters “Red” are shown as examples of conversion candidates.

  With reference to FIG. 7C, and in this case, when the conversion command shown in the lower row is selected, further expanded conversion candidates are displayed.

  For example, here, conversion candidates 1 to 8 are displayed, and full-width and half-width katakana characters, numbers, and Roman characters are shown.

  As for the Roman characters, it is assumed that a plurality of Roman characters are assigned to each dial key as described above. For example, the dial key “1” is assigned various symbols “., @,-, _, /”, “2” is “a, b, c”, “3” is “d, e, It is assumed that “g, h, i” is assigned to “f” and “4”. Similarly, it is assumed that the remaining Roman characters are assigned to other dial keys in the same manner. Here, a relationship between dial keys and Roman characters, a so-called Roman character conversion table will be described with an example.

  Therefore, for example, even when the character input “Akasatsu” is entered on the character input screen, a plurality of conversions are possible as conversion candidates, and not only kana characters but also katakana characters as shown here. It can be easily converted to romaji or numbers. Note that the dial keys assigned as described above as an example are assumed to be assigned to the dial keys described in the present specification.

Further, here, the conversion table for Kana characters and Roman characters has been described, but the same applies to the Kana character conversion table converted to Katakana characters.
JP-A-6-4517

  However, considering the number conversion table, each dial key has a configuration in which a single number is assigned, so the number conversion candidates for the same dial key, such as kana, katakana, romaji, or symbols, are Not provided. Therefore, even if the same dial key is pressed multiple times, only one number is converted as a conversion candidate because only one number is converted regardless of the number of key presses. Is displayed.

  Therefore, for example, in order to display a number such as “11” as a conversion candidate in the kana character input mode without entering the number input mode, “a” is displayed in the kana character input and the conversion command is selected. It is necessary to display the number “11”. Here, as a key operation, the dial key “1” is pressed once to display “A”, and the dial key “1” is pressed once as the next character to display “A”. There must be. Here, in order to display the next character, for example, a so-called cursor key or the like must be used to press the dial key “1” and another key to determine the previous character. Also increases compared to the numeric input mode.

  The present invention has been made to solve the above-described problem, and in a character input mode other than numbers such as kana characters, a number conversion candidate desired by the user can be obtained with the same number of operations as the number input mode. An object of the present invention is to provide a portable communication terminal device that can be created.

  The mobile communication terminal device according to the present invention is assigned to each of a display unit, a dial button provided corresponding to each number from 0 to 9, and a dial button from 0 to 9, respectively. A memory having a character conversion table for conversion in response to the number of times of continuous pressing, and a continuous pressing of the corresponding dial button displayed on the display unit with reference to the memory in a character input mode other than numbers A controller that displays characters of the character conversion table to be converted in response to the number of times on the display unit, and that creates numbers corresponding to the number of times the corresponding dial button is continuously pressed as conversion candidates.

  Another portable communication terminal device according to the present invention is assigned to and corresponds to each of a display unit, a dial button provided corresponding to each number from 0 to 9, and a dial button from 0 to 9. A memory having a character conversion table for conversion in response to the number of times the dial button is continuously pressed; a conversion button for executing character conversion; and a character input mode other than numbers, with reference to the memory, the display unit And a control unit for displaying on the display unit characters of the character conversion table to be converted in response to the number of times the corresponding dial button is continuously pressed. In response to pressing of the conversion button, the control unit creates numbers corresponding to the number of times the corresponding dial button is continuously pressed as conversion candidates.

  Preferably, when a plurality of character inputs are executed using a dial button, the memory sequentially stores the number of times the corresponding dial button is continuously pressed when inputting each character for each character. When at least one of the plurality of characters is deleted, the number of consecutive presses of the corresponding dial button pressed when inputting the deleted at least one character is deleted, and each character is The order of the number of consecutive presses of the corresponding dial button for each of the corresponding dial buttons is updated, and the control unit sequentially selects the corresponding dial button for each character based on the number of consecutive presses of the corresponding dial button stored in the memory. The number corresponding to the number of times of continuous pressing is generated as the conversion candidate.

  The control unit of the mobile terminal numerical device according to the present invention creates, as conversion candidates, numbers corresponding to the number of times the dial button is continuously pressed in a character input mode other than numbers. This makes it possible to create a number conversion candidate desired by the user with the same number of character inputs as in the number character input mode. Therefore, comfortable numeric input becomes possible.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

FIG. 1 is an external configuration diagram of a mobile communication terminal device according to an embodiment of the present invention.
Referring to FIG. 1, mobile communication terminal device 10 according to the embodiment of the present invention includes a display 2 that is a display unit and a key operation unit 20. The key operation unit 20 includes a dial key 1, a cursor key 3 disposed in the center, a determination key 4 provided in the center, and a character conversion key 5 for character conversion (in FIG. 1, simply displayed as a character. A dial-up key 6, a dial end key 7, a pictograph / symbol key 8 for use of a pictograph or a special symbol (shown simply as pictograph / notation in FIG. 1), and a clear key 11 (shown as CLR in FIG. 1).

The dial key 1 has keys displayed as “0” to “9”, “#”, “*”.
These keys have functions assigned according to the character input mode.

FIG. 2 is a schematic block diagram of the mobile communication terminal device according to the embodiment of the present invention.
Referring to FIG. 2, the mobile communication terminal device according to the embodiment of the present invention includes a control unit 15 that controls the entire device, a key operation unit 20 that receives an input of a key operation from a user, and a mobile communication terminal device. A memory 30 that stores various programs and tables for control, and a display unit 25 for displaying characters based on various commands based on key operations of the key operation unit 20, such as mails, are provided.

  FIG. 3 is a flowchart illustrating creation of a number conversion candidate in the kana character input mode according to the embodiment of the present invention.

  Referring to FIG. 3, the kana character input mode according to the embodiment of the present invention is started by first starting the character input mode (step S1). For example, a command such as e-mail is selected using the key operation unit 20, a character input screen such as e-mail is displayed on the display unit 25, and text input is executed by the key operation unit 20. As an example, it is assumed that the default value of the character input mode is set to the hiragana character input mode.

Next, the input of hiragana characters is executed by pressing the dial key (step S2).
Next, the number of times the dial key is pressed is input to a key pressing frequency table described later (step S3).

  Then, the Kana / Alphabet conversion key as the character conversion key 5 is pressed (step S4). It is assumed that the character conversion key 5 has a function as a Kana-alphanumeric conversion key for converting into katakana, romaji and / or numbers in the kana character input mode. In the numeric input mode, the character conversion key 5 can also be set to have a function as a hiragana / katakana conversion key for converting to hiragana and / or katakana. Here, it is set so that conversion to a plurality of types of characters is possible by pressing the character conversion key 5 once. However, the present invention is not limited to this, and by pressing the character conversion key 5 once, for example, Various combinations are possible depending on the setting, such as conversion to Katakana characters, further pressing to Roman characters, and further pressing to numbers.

  Along with this, the control unit 15 constructs (creates) a number candidate based on the number of times of pressing the dial key input to the key pressing number table (step S5).

  Then, the control unit 15 displays the number candidates and Roman characters constructed (created) on the display unit 25 together with conversion candidates such as katakana (kana-alphanumeric conversion candidate display). (Step S6). Note that here, characters such as roman letters and katakana are also displayed as conversion candidates, but it is also possible to use only number candidates, and the combination can be freely changed by setting. Is possible.

  FIG. 4 is a diagram for explaining the construction (creation) of number conversion candidates in the kana character input mode according to the flowchart of FIG.

  FIG. 4A is a diagram illustrating a character input screen displayed on the display unit 25. Here, a case where a command such as mail is selected using the key operation unit 20 and a text input such as mail is displayed on the display unit 25 is shown.

  FIG. 4B shows, for example, the dial key “1” once, the dial key “2” once, the dial key “3” twice, It is a figure explaining the character display and conversion candidate at the time of pressing "4" of a dial key 3 times.

  As shown in FIG. 4B, the letters “Akasatsu” are displayed according to the letters assigned to each of the dial keys. Note that the determination of each character based on the number of key presses is not determined even if the same dial key is pressed multiple times, but the previous dial key is pressed when another different dial key is pressed. The character based on the number of times shall be determined.

  In this example, full-width Katakana characters “Akashits”, full-width Hiragana characters “Akasatsu”, and half-width Katakana characters “Red” are shown as examples of conversion candidates. Here, in the Kana character input mode, an example has been described in which katakana characters are displayed as conversion candidates without key operation, but the present invention is not limited to this. For example, conversion candidates include numbers or It is also possible to set to display romaji without any key operation.

  Further, in this case, as described with reference to the flowchart of FIG. 3, the number of times the dial key is pressed is input to the key press count table stored in the memory 30.

FIG. 5 is a diagram illustrating a key press frequency table according to the embodiment of the present invention.
Referring to FIG. 5, here, a table is provided for storing the key types and the number of key presses for the first to 23rd characters.

  Based on the key press operation of the dial key described with reference to FIG. 4, the key type of the first character is the dial key “1”, and the number of key presses is one. The key type of the second character is the dial key “2”, and the number of key presses is one. The key type of the third character is the dial key “3”, and the number of key presses is two. The key type of the fourth character is the dial key “4”, and the number of key presses is three. In the key pressing frequency table, the maximum number of characters is 23 in this example in order to reduce the memory size. However, the number is not limited to this, and any number of characters can be expanded or reduced.

  Referring again to FIG. 4B, when the Kana-alphanumeric conversion key is pressed in this case, further expanded conversion candidates are displayed as shown in FIG. 4C.

  Here, conversion candidates No. 1 to No. 8 are displayed, and full-width and half-width katakana characters, numbers, and Roman characters are shown.

  Therefore, for example, even when the character input “Akasatsu” is input on the character input screen, a plurality of conversions are possible as conversion candidates. As shown here, not only hiragana characters but also katakana characters It can be easily converted to romaji or numbers.

  Here, for numbers, conversion candidates are constructed based on the number of key presses stored in the key press number table according to the embodiment of the present invention.

  That is, as shown in FIG. 4C, a number conversion candidate “1233444” is constructed and displayed.

  In accordance with the input conversion method described in the past, it is necessary to input “Akaasa tatata”. Then, when “sa” is input twice and “ta” is input three times, in order to display the next character, for example, a so-called cursor key is used to press a key different from the dial key. Since it is necessary to determine the previous character, the procedure is complicated and the number of operations is increased compared to the normal numeric input mode.

  As described above, in the kana character input mode, by storing the number of times the dial key is pressed in the key press number table, it is possible to create a number conversion candidate desired by the user with the same number of operations as in the number input mode. It becomes possible. In the above, the Kana character input mode has been mainly described, but the same applies to other character input modes such as the Katakana character input mode for inputting Katakana characters or the English character input mode for inputting Roman characters. Is possible.

  In this example, the case where the conversion candidate in FIG. 4C is constructed and displayed by pressing the Kana-alphanumeric conversion key has been described as an example, but the present invention is not limited to this. For example, even if the Kana alphanumeric conversion key is not pressed in step S4 in FIG. 3, the Kana alphanumeric conversion key is not pressed in the kana character input mode as shown in the lower column of FIG. 4B. Even in such a case, it is naturally possible to set and display the number candidates in the same manner as the katakana character conversion candidates as shown in FIG.

  As a result, compared to the conventional case where the display cannot be performed with the number of operations unless the dial key is operated after conversion to the number input mode, complicated operations are performed even in the character input mode other than numbers. Can be provided for the convenience of the user and comfortable numeric input is possible.

  In the above description, the case where new characters are displayed in order based on the key operation of the dial key on the character input screen has been described. However, the present invention is not limited to this, and even when the displayed characters are deleted, the key press count table is used A number conversion candidate desired by the user can be created.

  FIG. 6 is a diagram illustrating a key press count table when characters according to the embodiment of the present invention are deleted.

  FIG. 6A is the same key press count table as the key press count table described in FIG. Here, the case where the second character “ka” of “Akasatsu” is deleted by pressing the clear key together with the cursor selection will be described.

  FIG. 6B is a diagram illustrating a key press count table when the second character “ka” is deleted.

  As shown in FIG. 6B, the first character, the third character, and the fourth character in the key press count table of FIG. 6A are newly overwritten as the first character to the third character. That is, the updated state is shown. Specifically, the key type and the number of key presses from the first character to the fourth character are temporarily saved in another storage area, the key press number table is cleared to the initial value, and then saved. This can be realized by editing the information stored in the storage area and storing it again in the key press count table as updated information.

  As a result, the number conversion candidate is “133444”. Here, a case has been described in which adaptation is possible even when an input character is deleted. However, adaptation is also possible according to a similar method even in the case of insertion.

  As shown in this example, even when an arbitrary character is deleted or inserted, the number candidate for Kana alphanumeric conversion can be displayed appropriately by deleting and inserting the key press table at the location corresponding to that character. Is possible.

  Next, the case where the reverse input function of character input is installed in the mobile communication terminal device will be described.

  For example, it is assumed that the character input reverse feed function is set such that, for example, the previous character is displayed when the dial-up button 6 is pressed once. For example, if the dial key “1” is pressed a plurality of times, conversion is performed in the order of “A” → “I” → “U”. The reverse input function of the character input is that the dial-up button 6 is pressed. In this case, “U” → “I” → “A” is a function that can be converted in a conversion order opposite to the normal conversion order.

  It is assumed that such a function is assigned to the dialup button 6. In this case, the number of key presses can be subtracted from the number of key presses described above by the number of times the dial-up button 6 is pressed. However, in this case, it is assumed that the number of key presses is set not to be less than 1 based on the number of presses of the dial-up button 6. Although the function using the dial-up button 6 has been described here as an example, the present invention is not limited to this, and it is naturally possible to realize the same function using another button.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
