Description

  The present invention relates to a portable terminal having a character input / conversion function, a character input / conversion method, and an improvement of a program therefor.

2. Description of the Related Art Conventionally, portable terminals that have an electronic mail function and the like and are equipped with a character input function have been used. In these portable terminals, character input is generally performed by a multi-tap method in which a predetermined character is cyclically displayed each time a predetermined key is pressed, and a user selects a desired character. Patent Document 1 below discloses a technique for improving the efficiency of character input using such a multi-tap method.
JP 2001-195175 A

  However, the conventional technology has a problem that the order of the cyclic display of characters adopted in the multi-tap method is not compatible with the actual usage of characters in modern Japanese. For example, the prompt sound is described as a small “tsu”, but the circulation display is usually configured to be displayed at the end of the “ta” line. For this reason, it is usually necessary to press the key six times to input “tsu” as a prompt sound. Furthermore, in order to input characters in the “ta” line before and after “tsu”, it is also necessary to press the cursor movement key, but the probability that the characters in the “ta” line will appear after “tsu” is extremely high ( (There is also a survey result of about 56% for writing and about 77% for conversational), and the number of times the key is pressed when inputting a prompt sound is much larger than other characters.

  Further, in the above-mentioned Patent Document 1, a prompt sound is displayed and input by long-pressing a key, but there is a problem that it takes time to long-press the key.

  The present invention has been made in view of the above-described conventional problems. The purpose of the present invention is to provide a portable terminal having a character input / conversion function that can reduce the number of key operations in accordance with the actual use of Japanese, and character input. -To provide a conversion method and a program therefor.

  In order to achieve the above object, the present invention provides a portable terminal having a character input / conversion function, wherein characters or symbols in the “a” line to the “wa” line are assigned to the character input keys, and each key Each time the key is pressed, key display management means for cyclically displaying characters or symbols assigned to the key is provided, and the key display management means assigns a prompt sound to a key for displaying a muddy sound and a semi-voice sound. . It is preferable that the key display management means is configured to display a muddy sound or semi-muddy sound and a prompt sound simultaneously. Preferably, the key display management means can switch between a mode in which a prompt sound is assigned to a key that displays muddy and semi-voiced sounds and a mode in which a prompt sound is assigned to a key that displays a “ta” line.

  The present invention also relates to a method for inputting / converting characters, wherein characters or symbols in the “a” line to the “wa” line are assigned to the character input keys, and each time each key is pressed, the character is assigned to the key. In the key display management step for cyclically displaying the letters or symbols, the urging sound is displayed by the key for displaying the muddy sound and the semi-voiced sound.

  Further, the present invention is a program for causing a computer to function as a device having a character input / conversion function, wherein characters or symbols in the “A” line to the “W” line are assigned to the character input keys, and each key is assigned. When the character or symbol assigned to the key is circulated and displayed every time the key is pressed, a prompt sound is displayed by a key for displaying a muddy sound and a semi-voiced sound.

  According to the present invention, the sound is assigned to the key for displaying the muddy sound and the semi-turbid sound. Therefore, even if the character and the sound of the “ta” line continue, the increase in the number of times the key is pressed can be suppressed, The number of key presses can be reduced.

  Hereinafter, the best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described with reference to the drawings.

  FIG. 1 shows a block diagram of a configuration of an embodiment of a portable terminal having a character input / conversion function according to the present invention.

The key input is performed by the operation unit 12 shown in FIG. The operation unit 12 is configured by, for example, operation buttons (ten keys, cross keys, confirmation key) of a mobile terminal, etc., but when the present invention is applied to a personal computer or the like, area specifying means such as a keyboard and a mouse, A bar code reader or the like can also be used.

  The storage unit 14 includes, for example, a working RAM of the control unit 18, an EEPROM as a nonvolatile memory, a magnetic storage medium, and the like, and stores various data such as key input contents.

  The communication unit 16 communicates with the base station by a known method to realize a call function as a mobile communication terminal. When the present invention is applied to a PDA (Personal Digital Assistance), a personal computer or the like, the communication unit 16 is not necessarily required.

  The control unit 18 includes, for example, a CPU and controls these operations while exchanging data with the display unit 10, the operation unit 12, the storage unit 14, and the communication unit 16.

  The key setting unit 20 of the control unit 18 assigns characters or symbols from the “A” line to the “Wa” line to the character input key, and switches the character or symbol assigned to the key each time the key is pressed. Control the input process. In the present invention, it is possible to assign a prompt sound to a key for displaying muddy sounds and semi-voiced sounds, for example, “*” key, and to set a simple sound input mode in which a prompt sound is input when the key is pressed.

  The display control unit 22 mainly controls the content displayed on the display unit 10. Further, every time a character input key is pressed, the process of cyclically displaying the characters on each line in the order set by the key setting unit 20 is also controlled. The key setting unit 20 and the display control unit 22 constitute a key display management unit according to the present invention.

  The determination unit 24 performs control for determining whether the character input mode set by the key setting unit 20 is one of modes described later and whether or not a muddy sound or a semi-turbid sound is added to the character. I do.

  FIG. 2 shows an example of the key layout of the operation unit 12 used in the mobile terminal. In FIG. 2, “10” rows are assigned to different keys (1 to 0) for each of the numeric keypads, and the “*” key is assigned to the muddy sound and the semi-voiced sound, and the “#” key is assigned to the “#” key. Are assigned punctuation marks, punctuation marks and other symbols.

  3, 4, and 5 show examples of character lines assigned to each key (a line, ka line, etc.) and the order in which characters on each line are switched and displayed each time the key is pressed. . The data of the character allocation and cyclic display order is stored in the storage unit 14, and the key setting unit 20 reads out the data shown in FIG. 3, FIG. 4, or FIG. The display controller 22 performs the cyclic display of characters according to the present invention, and the character input operation is performed by the conversion key, the confirmation key, or the like of the operation unit 12.

  In FIG. 3, the assignment of a small “tsu” representing a prompt sound is deleted from the “4” of the numeric keypad to which the “ta” line is assigned, and “*” is added to the “*” key to which the muddy sound is assigned conventionally. Assigned. FIG. 3 shows an example in which the muddy sound and the prompt sound related to “ta” are assigned. That is, after selecting the character “ta” with the numeric keypad “4”, each time the “*” key is pressed, the display control unit 22 makes the order “da” → “t” → “da” → “ta”. The muddy sound and the prompt sound are displayed in circulation. With such a configuration, since the muddy sound and the prompt sound can be displayed simultaneously, an increase in the number of times the key is pressed when displaying the muddy sound and the prompt sound can be suppressed. Also, since the assignment of “tsu” from the numeric keypad “4” is deleted, an increase in the number of key presses can be suppressed even when prompting sounds and characters in the “ta” line are displayed in succession. Although the character “ta” has been described with reference to FIG. 3, other “ta” line characters, “ka” line characters, and “sa” line characters can be similarly configured.

  Also in FIG. 4, as in FIG. 3, the assignment of small “tsu” representing the prompt sound is deleted from the “4” of the numeric keypad to which the “ta” line has been assigned conventionally, and the muddy sound and the semi-turbid sound are assigned as compared with the conventional case. “Tsu” is assigned to the “*” key. In FIG. 4, an example is shown in which muddy sounds, semi-turbid sounds and prompt sounds related to “ha” are assigned. That is, after the character “ha” is selected with the numeric key “6”, each time the “*” key is pressed, the display control unit 22 “ba” → “pa” → “ha” → “ba” → “ Turbidity, semi-turbidity, and prompting sound are circulated and displayed in the order of “pa” → “ha”. In the case of FIG. 4 as well, an increase in the number of key presses can be suppressed as in FIG. In FIG. 4, the character “ha” has been described, but other “ha” line characters can be similarly configured.

  Also, in FIG. 5, as in FIG. 3, the assignment of small “tsu” representing the prompting sound is deleted from “4” of the numeric keypad to which the “ta” line has been assigned conventionally, and the muddy sound and the semi-turbid sound are assigned as compared with the conventional case. “Tsu” is assigned to the “*” key. FIG. 4 shows an example in which a prompt sound relating to “ma” is assigned. That is, after selecting the character “MA” using the “7” numeric keypad, each time the “*” key is pressed, the display control unit 22 cyclically displays the prompt sound in the order “MA” → “MA” (no prompt sound) Alternately displayed with characters). However, “ma” has no muddy sound or semi-muddy sound, and unlike FIGS. 3 and 4, muddy sound and semi-muddy sound are not assigned. In the case of FIG. 5 as well, an increase in the number of key presses can be suppressed as in FIG. In FIG. 5, the character “ma” has been described. However, other characters that do not have muddy and semi-voiced sounds, such as other “ma” line characters, “a” line characters, “na” line characters, The “ya” line character, the “ra” line character, and the “wa” line character can be similarly configured.

  According to the configuration of the present invention as described above, for example, when “was” is input, the number of key presses is reduced as compared with the conventional configuration in which “tsu” representing a prompt sound is displayed at the end of the “ta” line. Can be reduced. That is, in the conventional configuration, the numeric key “4” is pressed once to display “ta”, the “*” key is pressed once to display muddy sound, and the numeric keypad is used to display “t”. It is necessary to press “4” six times, press the move key or confirm key once, and press the ten key “4” once to display “ta”. For this reason, the total number of times the key is pressed is 10 times, the number of keys to be pressed is 3, and the 3 types of keys need to be switched 4 times.

  On the other hand, in the configuration of the present invention, the numeric key “4” is pressed once to display “ta”, the “*” key is pressed three times as shown in FIG. To display, the numeric keypad “4” may be pressed once. For this reason, the total number of times the key is pressed is five, the number of keys to be pressed is two, and the two types of keys may be switched twice. As described above, according to the present invention, the total number of times the key is pressed, the type of key to be pressed, and the number of times the key is switched can be reduced from the conventional configuration.

  3, 4, and 5 described above are examples of the full-width kana input mode, the same applies to the half-width kana input mode.

  In FIG. 6, the simple sound input mode in which the sound is assigned to the “*” key for displaying the muddy sound and the semi-turbid sound as described above, and the conventional input mode (“ta” line is assigned to “4” of the numeric keypad, Shows an example of a screen for switching setting. The display of the setting screen is controlled by the display control unit 22 and displayed on the display unit 10. In FIG. 6, “ON” and “OFF” buttons of the simple sound input mode are displayed on the screen. When “ON” is selected, the simple sound input mode is set by the key setting unit 20, and FIG. 3, FIG. 4 or FIG. The data shown in 5 is read. When “OFF” is selected, the conventional input mode is set. The user can appropriately set the input mode by using these switching buttons, and can input characters in a desired input mode that can be easily input by the user.

  7 and 8 show a flow of operations of the mobile terminal according to the present embodiment when the input mode is set on the setting screen shown in FIG.

  In FIG. 7, the determination unit 24 determines whether or not the prompt sound simple input mode is set (S1). If it is determined in S1 that the simple sound input mode is set, if the sound “tsu” is assigned to the numeric keypad “4” in the “ta” row, the assignment of the sound is deleted (S2). .

  If it is determined in S1 that the simple sound input mode is not set, if the sound key “4” in the “ta” row is not assigned to the sound key “4”, the sound sound is assigned to the keypad “4”. Assign (S3).

  After the above, the operation proceeds to the operation shown in FIG.

  In FIG. 8, the character input by the user using a desired key is acquired (S10). This character may be, for example, a full-width kana or a half-width kana.

  Next, the determination unit 24 determines whether or not the prompt sound simple input mode is set (S11). When it is determined in S11 that the simple sound input mode is set, the determination unit 24 determines whether or not the character acquired in S10 is a character that can add muddy sound (S12). For example, in the case of the character “TA”, it is a character that can add muddy sound, and in the case of the character “MA”, it is a character that cannot add muddy sound.

  If it is determined in S12 that the characters cannot be muffled, only the prompt sound “tsu” is assigned to the “*” key (muddy sound key) as shown in FIG. 5 (S13).

  Further, when it is determined in S12 that the character can add a muddy sound, the determination unit 24 determines whether the character can add a semi-turbid sound (S14). For example, in the case of the character “ha”, it is a character that can make a semi-turbid sound, and in the case of the character “ta”, it is a character that cannot make a semi-turbid sound.

  If it is determined in S14 that the character cannot be assigned a semi-turbid sound, the “*” key is assigned muddy sound, prompt sound, muddy sound + prompting sound in order from the top as shown in FIG. 3 (S15). If it is determined in S14 that the character can be a semi-turbid sound, the “*” key is used to display the muddy sound, the semi-turbid sound, the sound, the muddy sound + the sound, the semi-voiced sound from the top as shown in FIG. A muddy sound and a prompt sound are assigned (S16). Here, the muddy sound + sounding sound is to be displayed simultaneously when the sounding sound is followed by a sounding sound such as “Da”, for example. Is to display simultaneously.

  On the other hand, if it is determined in S11 that the simple sound input mode is not set, the conventional input mode is set, and the sound is assigned in the last order of the numeric keypad “4”. Moreover, the determination part 24 determines whether the character acquired by S10 is a character which can add a muddy sound (S17). If it is determined in S17 that the character cannot be muddy, no reaction will occur even if the “*” key is pressed.

  Further, when it is determined in S17 that the character can add a muddy sound, the determining unit 24 determines whether the character can add a semi-voiced sound (S18). If it is determined that the character cannot have a semi-turbid sound, a muddy sound is assigned to the “*” key (S19). As a result, when the “*” key is pressed, a display mode in which a muffled sound is added to the character acquired in S10 as usual. If it is determined in S18 that the character can be assigned a semi-turbid sound, a muddy sound and a semi-turbid sound are assigned to the “*” key in order from the top (S20). As a result, when the “*” key is pressed, the display mode is such that the characters acquired in S10 are added with muddy or semi-voiced sounds as before.

  As described above, the portable terminal of the present invention operates in accordance with the switching between the prompt sound simple input mode and the conventional input mode.

  In the present embodiment, the input mode switching setting can be performed within the same input mode, such as “full-width kana” and “half-width kana”, and there is no need to perform mode switching for each character input. From this point as well, the number of key presses during character input can be suppressed.
