  Hereinafter, a character input receiving device and a program according to an embodiment of the present invention will be described with reference to the accompanying drawings.

The character input reception device 10 according to the present embodiment includes a display unit 11, a control unit 12, a storage unit 13, and a speaker 14, for example, as shown in FIG.
The display unit 11 includes, for example, a capacitive touch panel, accepts various operation inputs (for example, tap, flick, scroll, and swipe) by the operator, and provides various operation guidance and operation inputs to the operator. Display the input characters and so on.
The display unit 11 includes at least an input character string display unit 21, a character switching key 22, a completion key 23, and the like as a first display screen 11 </ b> A that can accept various character inputs such as toggle type input and flick type input. , A delete key 24, a position designation key 25, and a plurality of character keys 26. Each of the keys 22 to 26 executes predetermined processes when a touch operation is performed with an operator's finger or the like.

  The input character string display unit 21 displays input character candidates and input character strings based on the input characters according to the toggle type input. The character switching key 22 switches the type of characters (for example, kana characters, alphanumeric characters, etc.) that can be input by the plurality of character keys 26. The completion key 23 completes the display of the input characters on the input character string display unit 21. The delete key 24 deletes the input character displayed on the input character string display unit 21. The position designation key 25 designates a position where an input character can be newly inserted into the input character string displayed on the input character string display unit 21.

  Different character groups, for example, character groups such as “a” line, “ka” line,..., “Wa” line of kana characters, etc. are assigned to each of the plurality of character keys 26. A cyclic order is set in advance for the characters in each character group. For example, a kana character order is set for the kana characters. For example, for the character group in the “A” line, the tour continues in order of “50” in order of “A”, “I”, “U”, “E”, “O”, “A”, “I”,. Order is set. In each character key 26, the first character in the cyclic order set in advance for the characters in each character group (for example, the character group in the “a” row of kana characters in the order of the Japanese syllabary) The image of the first character “A”) is displayed. The display of each character key 26 is set unchanged.

The control unit 12 accepts various character inputs such as toggle type input and flick type input to the display unit 11. Furthermore, the control unit 12 controls the display on the input character string display unit 21 and the output of the speaker 14 according to the state of character input on the display unit 11.
The storage unit 13 stores the input character displayed on the input character string display unit 21 and the candidate character string related to the input character string by the input character.
The speaker 14 outputs sound or signal sound according to the control of the control unit 12.

  The character input receiving device 10 according to the present embodiment has the above-described configuration. Next, the operation of the character input receiving device 10 will be described.

First, in step S01 shown in FIG. 2, the control unit 12 touches any one of the character keys 26 with the finger of the operator while the first display screen 11A that can accept character input is displayed on the display unit 11. It is determined whether or not an operation has been performed.
If the determination result is “NO”, the determination process of step S01 is repeatedly executed.
On the other hand, if this determination is “YES”, the flow proceeds to step S 02.
In step S02, the control unit 12 sets the display character of the operated character key 26 as an input character candidate. For example, when the character key 26 to which the character group of the “a” line of kana characters is assigned is operated, “a” that is the display character of the character key 26 is set as an input character candidate.

Next, in step S03, the control unit 12 inquires of the storage unit 13 whether there is a candidate character string including the input character string displayed on the input character string display unit 21, and the candidate character string is stored in the storage unit 13. Is stored in the candidate character string, the next character candidate (valid candidate character) following the input character string is extracted. When no input character is displayed on the input character string display unit 21, all characters that can be input by the plurality of character keys 26 are set as valid candidate characters. Then, it is determined whether or not the input character candidate is a valid candidate character.
If this determination is “NO”, the flow proceeds to step S 09 described later.
On the other hand, if this determination is “YES”, the flow proceeds to step S 04.
In step S <b> 04, the control unit 12 displays input character candidates on the input character string display unit 21.

For example, if the input character candidate “A” is a valid candidate character in a state where the input character string display unit 21 does not display the input character string, the input character string display unit 21 displays the input character string as shown in FIG. The character image of “A” is displayed.
Further, for example, when “a” is displayed as an input character string on the input character string display unit 21 and the input character candidate “a” is a valid candidate character, it is shown in (1) of FIG. As described above, the character image “Ah” is displayed on the input character string display unit 21.
Further, for example, when “a” is displayed as the input character string on the input character string display unit 21 and the input character candidate “o” is a valid candidate character, it is shown in (5) of FIG. Thus, the character image of “Ao” is displayed on the input character string display unit 21.

Next, in step S05, the control unit 12 determines whether or not a predetermined confirmation operation has been input.
If this determination is “YES”, the flow proceeds to step S 06.
On the other hand, if this determination is “NO”, the flow proceeds to step S 07.
The predetermined confirming operation is, for example, a touch operation with an operator's finger on the completion key 23 or the determination key (not shown).
In step S06, the control unit 12 determines the input character candidates as input characters following the input character string displayed on the input character string display unit 21, and newly sets the input character string and the input character. Enter the correct character string and go to the end.

In step S07, the control unit 12 determines whether or not the same operation of the same character key 26 has been performed within a predetermined time since the previous operation on the character key 26.
If this determination is “NO”, the flow proceeds to step S 06 described above.
On the other hand, if the determination is “YES”, the flow proceeds to step S08.
In step S08, the control unit 12 replaces the input character candidate with the forward feed corresponding to the number of continuous operations, and returns to step S03 described above.

For example, as shown in (2) of FIG. 3, when the character key 26 to which the character group in the line of the kana character is assigned is operated twice in succession, the character group is preset for this character group. "I" is newly set as an input character candidate according to the cyclic order, that is, the order of the order of the 50 notes.
Further, for example, as shown in (3) of FIG. 3, when the character key 26 is operated three times in succession, “U” is newly set as an input character candidate.
For example, as shown in (4) of FIG. 3, when the character key 26 is operated four times in succession, “e” is newly set as an input character candidate.
For example, as shown in FIG. 3 (5), when the character key 26 is operated five times in succession, “o” is newly set as an input character candidate.

  In step S09, the control unit 12 temporarily displays the input character candidates on the input character string display unit 21, and outputs a predetermined voice or signal sound together with the display erasure. In addition, when appropriate sound or signal sound or the like is output in step S04 described above, predetermined sound or signal sound or the like different from the appropriate sound or signal sound is output.

Next, in step S <b> 10, the control unit 12 determines whether the same operation of the same character key 26 has been performed within a predetermined time from the previous operation on the character key 26.
If this determination is “NO”, the flow proceeds to the end.
On the other hand, if this determination is “YES”, the flow proceeds to step S11.
In step S11, the control unit 12 replaces the input character candidate with the forward feed corresponding to the number of continuous operations, and returns to step S03 described above.

For example, as shown in (2) of FIG. 3, when the character key 26 to which the character group of the “a” line of the kana character is assigned twice in succession, the character group is previously stored. “I” is newly set as an input character candidate in accordance with the set cyclic order, that is, the order of the order of 50 notes. However, if the input character candidate is not a valid candidate character, the character image of “i” is temporarily displayed and then erased, and a predetermined sound or signal sound is output.
Further, for example, as shown in (3) of FIG. 3, when the character key 26 is operated three times in succession, “U” is newly set as an input character candidate. However, if the input character candidate is not a valid candidate character, the character image of “U” is temporarily displayed and then erased, and a predetermined sound or signal sound is output.
For example, as shown in (4) of FIG. 3, when the character key 26 is operated four times in succession, “e” is newly set as an input character candidate. However, if the input character candidate is not a valid candidate character, the character image of “e” is temporarily displayed and then erased, and a predetermined sound or signal sound is output.

The control unit 12 includes valid candidate characters in the character group assigned among the plurality of character keys 26 in a state where the first display screen 11A capable of accepting character input is displayed on the display unit 11. The character keys 26 corresponding to the non-character groups may be set to input disabled by inactive display such as grayout display.
For example, as shown in FIG. 4, when there is no valid candidate character in the character group of the “na” line of the kana character, the control unit 12 sets the character key 26 to which the character group of the “na” line is assigned. Is disabled due to gray out display. Then, when the inactive display character key 26 is operated, a sound or a signal sound for notifying that the input is impossible may be output.

As described above, the display of each character key 26 is invariant. For example, the character used for the display of the character key 26 in the character group assigned to the character key 26 is not a valid candidate character. Even if it exists, the character used for the display of this character key 26 becomes active display, without changing.
For example, as shown in FIG. 4, when the control unit 12 includes a valid candidate character other than the character “A” used for displaying the character key 26 in the character group of the “A” line of Kana characters. The character key 26 is set to the active display without changing the character “A” used to display the character key 26. When the character “a” that is not a valid candidate character is determined as the input candidate character by the toggle input to the character key 26, the character “a” is temporarily displayed on the input character string display unit 21. Then, a predetermined sound or signal sound is output together with the display erasure.

Moreover, the control part 12 can display the other screen which can accept various character inputs in the display part 11 other than the 1st display screen 11A.
For example, as shown in FIG. 5, the control unit 12 displays the second display screen 11 </ b> B including the character keys 31 to which all the characters that can be input are assigned, instead of the character keys 26 to which the character groups are assigned. You may display on the part 11. The control unit 12 switches between the first display screen 11 </ b> A and the second display screen 11 </ b> B when the touch operation with the finger of the operator is performed on the screen switching key 32.

  In addition, when the first display screen 11 </ b> A that can accept character input is displayed on the display unit 11, the control unit 12 performs this operation when any of the character keys 26 is touched with an operator's finger. You may change the input style received according to the operation state of touch operation. For example, the control unit 12 accepts a toggle type input when the duration of the touch operation is a short touch operation with a predetermined time or less, and flicks when the duration of the touch operation is a touch operation longer than the predetermined time. Change the input format to accept input.

For example, as illustrated in FIG. 5, the control unit 12 operates the character key 26 to which the character group of the “a” line of kana characters is assigned by a touch operation whose duration of the touch operation is longer than a predetermined time. In this case, a third display screen 11C that accepts flick input is displayed on the display unit 11. The third display screen 11C has at least the characters around the operated character key 26 and all the characters of the character group assigned to the character key 26 (that is, “I”, “U”, “E”, “ Each character of “O” is provided with an assigned character key 33. In the third display screen 11C, the control unit 12 performs inactive display such as grayout display of the character keys 26 and 33 to which characters (for example, “I” and “O” characters) that are not valid candidate characters are assigned. The character keys 26 and 33 to which characters that are valid candidate characters (for example, “A”, “U”, and “E” characters) are assigned are set to be inputable by active display. When any one of the active display character keys 26 and 33 (for example, the character key 26 of “A”) is selected as an input candidate, the control unit 12 further selects another active display. A display different from that of the character keys 26 and 33 may be performed.
In addition, the control unit 12 displays the third display screen 11C that accepts a flick input on the display unit 11 when the touch operation with the operator's finger or the like is finished (for example, the operator's finger is displayed on the display unit 11). 11), the third display screen 11C is switched to the first display screen 11A.

As described above, according to the character input receiving device 10 according to the present embodiment, the input character candidate display mode is switched depending on whether or not the input character candidate is a valid candidate character. Without changing, it is possible to make the operator accurately recognize input character candidates that are prohibited from being confirmed as input characters. As a result, since the input mode of the toggle type input is not changed, it is possible to support efficient toggle type input using the candidate character string without giving the operator a sense of incongruity, and improve operability and convenience. Can do.
Furthermore, for input character candidates that are not valid candidate characters, the operator can be alerted by sound output such as voice or signal sound, and input character candidates that are prohibited to be confirmed as input characters are It can be made to recognize even more accurately.
