Description

  The present invention relates to a portable electronic device having a character input function such as a cellular phone.

  In recent years, various functions that require character input such as a telephone directory function and an e-mail function have been added to portable electronic devices such as mobile phones, and therefore, a character input function is also provided. A conventional cellular phone is provided with a numeric keypad for inputting telephone numbers and characters as shown in FIG. 2, and a user operates the numeric keypad to input characters. This character input method using the numeric keypad is a method for selecting a desired character from characters assigned in advance according to the number of times the numeric keypad is operated. For example, the “1” input key is assigned the kana character “A line”, and one of the characters “A ~ O” is selected according to the number of operations of the “1” input key. Can be entered.

In these portable terminal devices, character input is generally performed by a multi-tap method in which a plurality of assigned characters are cycled and displayed every time a predetermined key is operated, and a user selects a desired character. is there. 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, in the conventional technology, when characters assigned to one numeric keypad are input continuously, after the numeric keypad operation for inputting the first character is performed, an operation for changing the character input position is performed. Furthermore, it is necessary to perform the numeric keypad operation for inputting the second character again, and the numeric keypad operation for character input is performed with an operation for changing the input position interposed therebetween, so that the operability is reduced. There was a problem.

  For example, if you want to input “If you devour ...”, you need to operate the numeric keypad (“2” input key) to which the line is assigned and change the character input position. Perform the input operation (one operation of the “2” input key), then perform the operation to change the character input position to the right (the operation of the right key of the cross key), and then input the “ki” (Turn the “2” input key twice), then perform the operation to change the character input position to the right side (the operation of the right key of the cross key), and then input the “ku” (“ 2 ”is operated three times by the input key),“ Kakiku ”is input. In this way, when characters (or lines of characters) assigned to the same input key are input continuously, the same input key is pressed again after switching the character input position by operating the right key of the cross key. It is configured to input new characters by operation. Therefore, an operation only for changing the character input position is required, and smooth character input is difficult.

  Further, in the conventional technique, a prompt sound of “tsu” is assigned to the “4” input key of the numeric keypad, and a roaring sound of “nya, yo,” is assigned to the “8” input key.

  For example, if you want to input "Catch", the operation of the numeric keypad ("2" input key) to which "Ki" is assigned, the operation of the numeric keypad ("8" input key) to which the roar is assigned, and the prompt sound It is necessary to operate the assigned numeric keypad (“4” input key).

  However, since the roaring sound and the prompt sound for the first character “K” are assigned to different input keys, the input operation becomes complicated, and smooth character input becomes difficult.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a portable electronic device that enables smooth character input.

  The portable electronic device according to the present invention includes a display unit, an input key assigned with a predetermined character, an operation unit having a position change key for changing a character input position on the display unit, and the input key. A control unit that displays the predetermined character assigned to the input key according to the operation of the display unit and performs a character input process, and the control unit is configured to operate the input key according to the operation of the input key. When the character input position is changed to the next input position with respect to the first character in accordance with the operation of the position change key after the first character of the predetermined characters is input and displayed, the next character Character input processing is performed by displaying a related character for the first character at an input position.

  In the portable electronic device of the present invention, smooth character input can be made possible.

  FIG. 2 is a diagram showing a part of the configuration of the key input unit 3 of FIG. 1. The key input unit 3 is determined as a numeric keypad 31 for inputting a telephone number, characters, etc., and up / down / left / right keys 32a to 32d. A cross key 32 having a key 32e, and function keys 33a to 33d for various functions arranged on four sides of the cross key 32 are provided. In the configuration shown in FIG. 2, the numeric keypad 31 has character input functions assigned to character (number) input keys 1 to 10. For example, the “1” input key is assigned the kana character “A line” (predetermined character). In addition, the “2” input key is assigned a “kana line” character (predetermined character) and an alphabet (alphabet) characters “A to C” (predetermined character).

  When performing character input using these character input keys, it is possible to select an input character corresponding to the number of times the character input key is operated (pressed number) in each character input mode (such as the kana input mode or the alphabet input mode). . For example, in the Kana input mode, pressing the “1” input key once will select “A” as the input character, “yes” when pressed twice, “u” when pressed three times, “e” when pressed four times. ”And“ O ”are selected as input characters by pressing the button five times. Furthermore, when the number of times of pressing is repeated, similarly, according to the number of times of pressing, it is sequentially selected according to the order of “A → I → U → E → O → A →” (predetermined order) and displayed in a cyclic manner. Character input processing is performed by repeating. In the alphabet input mode, if the “2” input key is pressed once, “A” is selected as the input character, “B” is selected as the input twice, and “C” is selected as the input character when pressed three times. If the number of times of pressing is further increased, selection of A to C is repeated and repeated according to the number of pressing times. In this way, each time the input key is operated, the character or symbol assigned to the character input key is cyclically displayed on the display 5 by the display control unit 6 according to a predetermined order.

  The cross key 32 has four direction keys, an upper key 32a, a lower key 32b, a right key 32c, and a left key 32d for selecting various items displayed on the display (display unit) 5, and the four direction keys. And a determination key 33e for determining the item selected by the operation.

Next, the character input process of the mobile phone in this embodiment will be described.
When a mail function or the like having a character input function is activated to enter a character input mode, a cursor indicating a character input position is displayed on the screen of the display 5. In this state, the user can input a desired character by operating (pressing) any input key of the numeric keypad 31, and the input character is displayed on the screen of the display 5. In the character input mode, when the character type of the input character is set by operating the function key, the character assigned to the input key (numeric keypad) is input according to the character type. For example, when “Hiragana” is set as the character type, the first character of the input character is operated by operating the first input key (for example, pressing the “1” input key once assigned to the line). After the input, when another second input key is operated (for example, “2” input key to which a line is assigned is pressed once), a desired hiragana (for example, “red”) is input. Displayed. When the input key operated in this way is changed, it is determined that the next character is input, the character input position is automatically changed, and continuous character input processing is performed.

  When it is desired to continuously input characters assigned to one input key, conventionally, after an arbitrary input key is operated to input the first character, a display unit (display) is displayed during character input processing. 5) The character input position is changed to the next position (right adjacent position) of the first character by operating the right key 32c of the cross key 32 in which the function for changing the character input position in 5) is set. Then, the second character is input by operating the same input key. In this conventional configuration, in order to change the character input position, the operation of the right key 32c is necessary, and the operation of the right key only changes the character input position. When inputting characters, it was necessary to operate the same input key again from the beginning.

  That is, when the character input position is changed by the operation of the right key 32c, in order to continuously input the characters assigned to one input key, the input to which the previously input characters are allocated is input. Although there is a high possibility that the keys will be operated continuously, it is necessary to operate the same input key again from the beginning after the character input position is changed by operating the right key. The input operation could not be performed.

  In order to solve such a problem, when a long press of an input key is detected, it is determined that characters assigned to the input key are continuously input, and the character input position is changed by detecting the long press. Configuration is assumed. However, in the case of this configuration, a long press operation is required for character input that is normally performed by a short press of the input key. Therefore, the input operation becomes complicated, and smooth character input cannot be expected so much.

  In addition, when the no-operation time has elapsed from the operation of the input key, it is determined that characters assigned to the input key operated before that are continuously input, and this no-operation state is maintained for the predetermined time. A configuration is assumed in which the character input position is automatically changed after a lapse. However, if you want to continuously input the characters assigned to one input key, wait for the input position to be automatically changed after a predetermined time has elapsed after entering the first character. Therefore, it is considered that a smooth input operation cannot be expected so much.

  Therefore, in the mobile phone according to the present embodiment, in order to continuously input characters assigned to one input character, the cross key is used after an arbitrary input key is operated to input the first character. By operating the right key 32 (position change key for changing the character input position) 32c, the character input position is changed to the right side of the first character, and the arbitrary input position is changed to the changed input position. A character (predetermined character) assigned to the input key is temporarily input and displayed as the first related character. When a plurality of characters are assigned to the arbitrary input key, the first character in the predetermined order among the plurality of characters is provisionally input together with the change of the input position by the operation of the right key 32c. When it is desired to input a character other than the first character as the second character, a plurality of characters assigned according to a predetermined order are sequentially temporarily input in accordance with the operation of the lower key (selection key) 32b of the cross key 32. Displayed.

  Then, when the determination key 32e of the cross key 32 is operated in a state where the second continuous character is temporarily input, the temporarily input character is determined as the second input character. After the input of the second character is determined, the processing is the same as the input processing so far. If the right key 32c is input again from the state in which the second character is temporarily input, it is determined that the characters assigned to the same input key are continuously input again. The character input position is changed to the right next to the second character, and the character assigned to the arbitrary input key is temporarily input and displayed at the changed input position, and then the same processing is executed. Is done.

Next, this character input process will be described with reference to the flowchart shown in FIG.
When the creation of a new mail starts after the mail function is activated, the character input function is executed. By executing this character input function, a character input process is started, and a character input screen is displayed on the display 5, and a cursor indicating the character input position is lit on an initial position on the screen. At the start of this character input process, “Hiragana” is set as the default character type of the input character. It should be noted that the character type of the input character can be converted to an arbitrary character type by operating the function keys.

  With the start of the character input process, it is determined whether or not any of the input keys (input keys “1” to “0”) of the numeric keypad 31 is operated in step S1 shown in the flowchart of FIG. . If it is determined in step S1 that any of the input keys is not operated, the same step process is repeated until it is determined that any of the input keys is operated. If it is determined in step S1 that one of the input keys has been operated, the process proceeds to step S2, and a plurality of characters (for example, “2” input assigned to the input key whose operation has been determined in step S1 are input. When a key is operated, an input character is selected according to the number of operations in accordance with a predetermined order from “a ~ o” hiragana characters), and the character input position on the display 5 is set to the selected character as an input character. To display. The process of step S2 is continuously executed when the same input key is continuously operated, and when a key other than the input key determined to be operated in step S1 is operated, step S2 is executed. It progresses to the process after S3.

  If any key other than the input key whose operation is determined in step S1 is operated, the process proceeds to step S3, and an input key different from the input key determined in step S1 in the numeric keypad 31 is operated. It is determined whether or not. If it is determined in step S3 that a different input key has been operated, the process proceeds to step S4. In step S4, a character input process corresponding to the determined operation of the different input key is performed. The character input process here is the same as the conventional character input process. First, the character input position (cursor lighting display position) is automatically set to the position to the right of the previous input character by operating different input keys. A character corresponding to the operation of a different input key is input and displayed at the changed position.

  If it is determined in step S3 that the operated key is not a different input key, the process proceeds to step S5 to determine whether or not the character input position change key has been operated. Specifically, it is determined whether or not the right key 32c of the cross key 32 has been operated. If it is determined that the right key 32c as the input position change key has been operated, the process proceeds to step S6. In step S6, a continuous character input process is executed by operating the input position change key (right key) 32c. In this continuous character input process, first, the character input position (cursor lighting display position) is automatically changed to the position to the right of the previous input character (next input position), and step S1 is set to this changed input position. The character assigned to the input key whose operation has been determined is automatically temporarily input. Furthermore, by operating the upper key 32a or the lower key 32b of the cross key 32 as a selection key, the characters assigned to the input keys are selected in a predetermined order, and any character can be selected. .

  For example, after the operation of the “2” input key to which the character of the “ka” line is assigned in the numeric keypad 31 is determined in step S1, the input position change key (right key 32c) is operated in step S5. If it is determined, the character input position (cursor lighting display position) is automatically changed to the right of the previously input character in the “ka” line, and the first character input operation is performed. Of the characters assigned to the “2” input key, the first character “ka” in a predetermined order is provisionally input. When it is desired to input characters in the “ka” line other than “ka”, the upper key 32 a or the lower key 32 b of the cross key 32 as a selection key is operated, so that a predetermined order (ka, ki, k, In accordance with this, a plurality of characters assigned to the “2” input key are cyclically displayed and the input characters are selected.

  Next, when the process of step S4 is completed, when the process of step S6 is completed, or when it is determined that the key operated in step S5 is not an input position change key, the process proceeds to step S7. In this step S7, it is determined whether or not a character conversion key for converting characters input so far into kanji or the like has been operated. The character conversion key is the lower key 32b of the cross key 32. If it is determined that the lower key 32b is operated, the process proceeds to step S8. When the continuous character input process in step S6 is performed, the lower key 32b functions as a selection key for the assigned character. In this case (when the process proceeds to step S7 via step S6). The function key 33a is set as a character conversion key, and it is determined whether or not the function key 33a has been operated.

  If it is determined in step S7 that the character conversion key (down key 32b or function key 33a) has been operated, the process proceeds to step S8, the conventional character conversion process is executed, and the process proceeds to step S9. If it is determined in step S7 that the character conversion key has not been operated, the process proceeds to step S9 without going through step S8.

  In step S9, it is determined whether or not the enter key 32e has been operated. If it is determined that the enter key 32e has not been operated, it is determined that character input will be continued, and the processes in and after step S3 are repeated. If it is determined in step S9 that the enter key 32e has been operated, it is determined that the input character has been confirmed, the process proceeds to step S10, where character input is determined, and return processing is performed.

  Next, the operation when the user of the mobile phone of FIG. 1 inputs characters will be described with reference to FIG. The example of the character input operation shown in FIG. 3 is a case where “Kakiku” is input with hiragana.

  At the time of this character input, the user of the mobile phone operates once the “2” input key to which the character of the “ka” line is assigned in the numeric keypad 31 while the character input function is being executed. . By this operation, the first character “KA” among the characters in the “KA” line assigned to the “2” input key is input and displayed at the character input position of the display 5. At this time, a plurality of prediction conversion candidates are displayed in the lower column of the display 5, and conversion processing can be performed by selecting a prediction conversion candidate by operating a selection key (up key 32a or down key 32b). The function key 33a is assigned a function for displaying the next item of the prediction conversion candidate, and the function key 33c is assigned a function for displaying the previous item of the prediction conversion candidate.

  When the right key 32c of the cross key 32 is operated in a state where “ka” is input and displayed by one operation of the “2” input key, continuous character input processing is executed. In this continuous character input process, the character input position is changed to the next input position of the character “ka” that has been input and displayed first, and the cursor is lit up on the right side of the character “ka”. Furthermore, at the changed character input position, the character assigned to the “2” input key to which the previously input character “ka” is assigned is automatically temporarily input and displayed. Here, the first character “ka” in the “ka” line is temporarily input and displayed. A plurality of characters assigned to the same “2” input key are displayed in a predetermined order below the temporarily input character “ka”. The user operates the lower key 32b of the cross key 32 when the character to be input following the previous input character “ka” is different from “ka” which is temporarily input, thereby displaying “ A desired character is selected from the characters in the “ka” line (characters assigned to the “2” input key). Here, in order to input the character “ki”, by operating the down key 32b once, as shown in FIG. 4C, the character “ki” is the next character after the previous input character “ka”. Is temporarily displayed.

  As shown in FIG. 4B, the characters “ka” temporarily displayed at the character input position and the characters “ki-ko” displayed in a list are surrounded by one frame and displayed. In this way, by temporarily displaying the characters “ka” that are temporarily input and the characters “ki-ko” that can be temporarily input and displayed in a frame and highlighted, the user of the mobile phone It can be easily recognized that the input process is being executed. In addition to this frame display, the user can change the display color of the cursor, display an icon indicating that continuous character input processing is being executed in the upper right part of the screen, and output audio to the user. You may make it alert | report that the continuous input process is performed. As shown in FIG. 4B, in the state where the character “ka” or the character “ki” is temporarily input, the predicted conversion candidate combined with the previous input character “ka” is displayed in the lower column of the screen. Has been.

  As shown in FIG. 4C, when the character “ki” is temporarily input and the right key 32c, which is a character input position change key, is operated, as shown in FIG. The temporarily input character “ki” is determined to be input, and the continuous character input process is continuously executed. In this case, the character input position is changed to the next input position of the previously input character “KI”, the cursor is lit on the right of the character “KI”, and the changed character input position is displayed. Similarly, the first character “KA” assigned to the “2” input key is automatically temporarily input and displayed, and the other characters “KIKO” are displayed in a row below.

  When the selection key (down key) 32b is operated twice from the state shown in FIG. 4D, as shown in FIG. 4E, the changed character input position (the previous input character “KI”) is changed. The character “ku” is provisionally entered on the right). In this state, when the enter key 32e of the cross key 32 is operated, the input of the character “ku” that is temporarily input is determined, and the input “kaki” that has been input so far is the same as the conventional input. Processing is possible. Further, when the function key 33a is operated, a conversion process for selecting an arbitrary conversion candidate from the prediction conversion candidates displayed on the screen can be executed. When the function key 33c is operated, the temporary input process in the continuous character input process is canceled, and the character “Kaki” input so far is determined as the input character.

  When the right key 32c, which is the character input position change key, is operated again from the state shown in FIG. 4E, the continuous character input process is continuously executed, and the character input position (cursor lighting display) The position) is changed to the right side, and the character assigned to the “2” input key is temporarily input again. Further, when an input key other than the “2” input key is operated instead of the right key 32c, which is a character input position change key, the character input position is similarly changed as in the conventional case, and the different input operated. Input processing of characters assigned to keys is performed.

  As described above, in the mobile phone according to the present embodiment, in the character input process, when the characters assigned to one input key are continuously input, the character input position change key is input after the previous character is input. By operating the (right key 32c), the character input position is automatically changed, and characters assigned to the same input key are automatically provisionally input. It is possible to continuously input characters assigned to the character, and it is possible to easily input characters assigned to one input key, improve the input operability, and smoothly An input operation can be made possible.

  In addition, in this continuous input process, a plurality of characters assigned to the same input key can be displayed on the screen and any character can be selected, so that a plurality of characters are assigned to the input key. Even if it is a case, arbitrary characters can be selected and input easily. Furthermore, when this continuous character input process is executed, the mobile phone can be used by displaying the temporarily input characters and input candidate characters in the frame, changing the cursor display color, displaying icons on the screen, and outputting voices. By notifying the user that continuous character input processing is in progress, it is recognized that the characters assigned to the input key that was previously operated are automatically input continuously by operating the input position change key. It can be made.

  In addition, characters that are continuously input during the execution of the continuous character input process by operating the input position change key (right key 32c) can be arbitrarily selected by operating the selection key (lower key 32b). Since the change key (right key 32c) and the character selection key (upper key 32a and lower key 32b) are each composed of a part of the cross key 32 and arranged close to each other, the start operation of the continuous character input process (right The operation of the key 32c) and the input character selection operation (the operation of the upper key 32a or the lower key 32b) can be continuously and smoothly operated, and the input operability can be further improved.

  Next, a modification of this embodiment will be described. In the above-described embodiment, when the character input position change key (right key 32c) is operated during the character input process, it is assigned to the same input key as the related character for the previously input character (first character). The character input processing is performed by displaying the characters being displayed. On the other hand, in this modified example, the moji character ('), the semi-moji character (°), the prompt character (tsu), and the moji character (nya, yu, yo, a, i, ぅ, ee, ぉ) Among them, a character corresponding to the previous input character is automatically input as an associated character for the previous input character by operating the character input position change key (right key 32c).

  Here, the character corresponding to the previous input character is set to a character that may be continuously input to the previous input character among the muddy character, the semi-voice character, the prompt character, and the stuttering character. For example, if the previous input character is “ki”, “gi, ki, kya, kyu, kyo” is assumed, so the related characters in this case (characters corresponding to the previous input characters) A moji character, a prompt character, and a roar character are set.

  Conventionally, such muffled characters, semi-voiced characters, prompting characters, and roaring characters have been assigned to different input keys, so it has been necessary to operate any character corresponding to the characters that are continuously input . On the other hand, in the configuration of the present modification, a character corresponding to the previous input character among the muddy character, the semi-voiced character, the prompt character, and the roar character is input by operating the input position change key (right key 32c). Therefore, the operability is improved and a smooth character input operation can be performed.

  Next, with reference to FIG. 5, the operation when the user of the mobile phone inputs characters in this modification will be described. The example of the character input operation shown in FIG. 5 is a case where “Catch” is input in katakana.

  First, in a state where the character input function is being executed, by changing the character type of the input character to “katakana”, katakana input is made possible. Then, the “2” input key to which the characters of the “K” line of the numeric keypad 31 are assigned is operated twice. As a result of this operation, as shown in FIG. 5A, the second character “K” of the characters in the “K” line assigned to the “2” input key is input, and the character input on the display 5 is performed. Displayed in position.

  Then, when the right key (position change key) 32c of the cross key 32 is operated in a state where “K” is input and displayed by the two operations of the “2” input key, FIG. As shown in FIG. 4, the character input position is changed to the next input position of the character “K” input and displayed first, and the cursor is lit up on the right side of the character “K”. Furthermore, in the changed character input position, the mojion character, the mojion character, and the mokuon character, which are characters corresponding to the character “ki” inputted earlier among the makuon character, the semi-tona character, the sound character, and the sound character. A character can be input as a related character of the previous input character. In this case, as shown in FIG. 5B, a muffled character is provisionally input, and an arbitrary character is selected and input from these characters by operating the selection key (up key 32a or down key 32b). can do. In this case, in order to input the stuttering character “a” following the previous input character “ki”, as shown in FIG. 5C, the stuttering character “a” is changed by operating the down key (selection key) 32b. You can select and enter.

  Subsequently, in order to input the prompt character “”, the character input position is automatically changed by operating the character input position change key (right key 32 c) again, and the input character “C” is changed to the previous input character “C”. Subsequently, a prompt sound character, which is a character corresponding to the previously input character “a”, is temporarily input among the cloud sound character, the semi-voice character, the prompt sound character, and the stuttering character. In this case, since the corresponding related character is only a prompt character, no selection operation is required.

  Subsequently, in order to input the character “h”, by operating the “4” input key to which the character of the “ta” line is assigned twice, the character input position is changed as in the conventional character input process. The second character “H” that is automatically changed and assigned to the “4” input key is input and displayed.

  As described above, in this modification, by operating the character input position change key, at least one of the muddy character, the semi-voiced character, the prompting character, and the stuttering character corresponding to the previously input character is related. By making it possible to input as characters, when inputting these muffled characters, semi-voiced characters, prompting characters, and stuttering characters following the previous input characters, the corresponding characters that correspond only by operating the character input position change key are displayed. Since input is possible and there is no need to use different input keys according to the characters to be input, the input operation can be easily performed, and a smooth input operation can be performed.

  In the above-described embodiment, the mobile phone has been described as an example of the mobile electronic device. However, the same configuration can be applied to character input processing in a mobile electronic device other than the mobile phone. The type of characters assigned to the input keys is not limited to hiragana and katakana, and may be alphabetic characters or symbols. The same processing is performed when these characters are input. Also good.

  In addition, a configuration for performing continuous character input processing that allows a character assigned to the operation key of the previous input character to be input continuously by operating the character input position change key, and corresponding to the previously input character The configuration that allows input of at least one of muddy character, semi-voiced character, prompting character, and stuttering character has been explained, but the user of the mobile phone can select and set any configuration You may be able to do it.
