Description

  The present invention relates to an information processing apparatus and a character input control program.

  2. Description of the Related Art In recent years, character input using a 10 key to which numbers from 0 to 9 are assigned is performed in character input for a mobile phone or the like. For example, when there are 50 sounds in hiragana, it is common that about 10 characters are not enough to represent a certain language. Therefore, in an input method in which one character is represented by one key, there are not enough characters that can be represented by ten keys. Therefore, in the character input using the 10 keys, a character corresponding to the number of times of pressing is input by pressing the same key a plurality of times. There are cases where characters are input by adding a few keys to 10 keys, but in this case too, there are not enough characters that can be expressed. Therefore, in the following description, an input using a key obtained by adding a key displaying * or # to the 10 key will be described as an input using the 10 key.

  As such a character input method using 10 keys, a conventional technique for displaying a character string similar to the input character string as a candidate has been proposed. In addition, a conventional technique has been proposed in which conversion candidates are displayed in descending order of the number of pressings when inputting a character subsequent to a character string that has already been input. Also, a conventional technique has been proposed in which a software keyboard is displayed with a large probability of being used as a character subsequent to a character string already input in a conversion candidate of the input character string.

  However, in the character input using the 10 keys, when the characters assigned to the same key are continuously input, the same key is repeatedly pressed. When the number of times is pressed, one character is input. Therefore, to input characters assigned to the same key continuously, after entering the first character, move the character input position to the next position and then enter the next character. Is called. As described above, when characters assigned to the same key are continuously input, the operation of character input becomes complicated, resulting in poor operability. In particular, the operation of character input has become very difficult for elderly people and operators who are not accustomed to character input using 10 keys.

  In addition, in the conventional technique for displaying a character string similar to the input character string as a candidate, an input mistake can be compensated, but the operability of continuous input of characters assigned to the same key is not improved. Also. In the conventional technology that displays conversion candidates in descending order of the number of times of pressing the next character after the already input character string, the number of key pressings in character input can be reduced, but it is assigned to the same key The operability of continuous character input is not improved. Furthermore, with the conventional technology that displays characters that have a high probability of being used as characters following the already entered character string, it is easier to find the next character to be entered. It is the same that the property does not improve.

  The disclosed technique has been made in view of the above, and an object thereof is to provide an information processing apparatus and a character input control program that facilitate continuous input of characters assigned to the same key and improve operability. And

In one aspect, the information processing apparatus and the character input control program disclosed in the present application are such that the character input control unit determines a character corresponding to the number of times the character input key is pressed according to the number of times the character input key is pressed. A predetermined basic character string in the column is acquired, and the acquired basic character string is displayed on the display unit. The character candidate acquisition unit acquires a character string corresponding to the number of times the one character input key is pressed. A candidate display control part displays the character string acquired by the said character candidate acquisition part on the said display part so that selection is possible. The character display control unit causes the display unit to display the selected character string instead of the basic character string based on the selection of one character string from the character strings displayed by the candidate display control unit. . The prediction conversion candidate storage unit stores prediction conversion candidates corresponding to the character strings. The prediction conversion candidate acquisition unit acquires a prediction conversion candidate corresponding to the basic character string from the prediction conversion candidate storage unit. The prediction conversion candidate display control unit displays the prediction conversion candidate acquired by the prediction conversion candidate acquisition unit on the display unit in a selectable manner, and selects one of the character strings displayed by the candidate display control unit. When a character string is selected, the predicted conversion candidate for the selected character string is displayed on the display unit instead of the predicted conversion candidate for the basic character string. Further, the character display control unit receives selection of one prediction conversion candidate from the prediction conversion candidates displayed by the prediction conversion candidate display control unit, and replaces the character string displayed on the display unit. The prediction conversion candidate selected in this way is displayed on the display unit.

  According to one aspect of the information processing apparatus and the character input control program disclosed in the present application, it is possible to facilitate continuous input of characters assigned to the same key and improve operability.

  Embodiments of an information processing apparatus and a character input control program disclosed in the present application will be described below in detail with reference to the drawings. The information processing apparatus and the character input control program disclosed in the present application are not limited by the following embodiments. In particular, in the following description, a mobile phone is described as an example of the information processing device. However, the information processing device is not limited to this, and may be any device that inputs different characters by pressing the same key. Hereinafter, an arrangement of one character or a plurality of characters is referred to as a “character string”.

  In this embodiment, a mobile phone will be described as an example of the information processing apparatus. In the following description, the 10 keys of a mobile phone will be described as an example of character input keys for inputting characters. Assume that hiragana is assigned to each of the 10 keys of the mobile phone. For example, for keys representing “1”, “A”, “I”, “U”, “E”, “O”, “A” (lowercase “A”), “I” (lowercase “I”), “ぅ (lowercase) No. “u”), “e” (lowercase “e”), and “ぉ (lowercase“ o ”)” are assigned ten character strings.

  FIG. 1 is a block diagram of the mobile phone according to the first embodiment. As shown in FIG. 1, the mobile phone according to the present embodiment includes a storage unit 1, an input control unit 2, a character candidate acquisition unit 3, a prediction conversion candidate acquisition unit 4, and a display control unit 5. Although not shown, the mobile phone according to the present embodiment has 10 keys, a confirmation button, and a selection key. Further, although not shown, the mobile phone according to the present embodiment has a display unit such as a liquid crystal screen. Furthermore, the mobile phone according to the present embodiment has buttons for selection corresponding to three areas, which will be described later, that is, a character input area displayed on the display unit, a prediction conversion candidate display area, and a candidate character string display area. Yes.

  The storage unit 1 is a storage device such as a hard disk or a memory. The storage unit 1 includes a candidate table storage unit 11 and a prediction conversion candidate storage unit 12.

  The candidate table storage unit 11 stores the candidate table shown in FIG. FIG. 2 is a diagram illustrating an example of a candidate table. As shown in FIG. 2, the candidate table has a key press count column 101, a normal display column 102, and a candidate display column 103. The key press count column 101 indicates how many times one of the arranged keys is pressed. The normal display column 102 indicates a basic character string that is a predetermined character string corresponding to the key press count described in the key press count column 101. The candidate display column 103 indicates a candidate character string including a basic character string corresponding to the key press count described in the key press count column 101.

  For example, in the column 111 of the key press count column 101, four presses of the “1” key among the ten keys are described. The basic character string corresponding to the case where the “1” key among the 10 keys is pressed four times is “e” described in the column 112 of the normal display column 102. The candidate character string corresponding to the case where the “1” key among the 10 keys is pressed four times is described in the column 113 of the candidate display column 103, “Oh, ah, ah, ah, yes. "Oh, good, good, good, good".

  As shown in FIG. 2, when the key “1” is pressed once, “A” is assigned to the basic character string. When the “1” key is pressed twice, “i” is assigned to the basic character string. When the “1” key is pressed three times, “u” is assigned as the basic character string. When the “1” key is pressed four times, “e” is assigned as the basic character string. When the “1” key is pressed five times, “O” is assigned to the basic character string. After that, the basic character strings are assigned “a”, “i”, “ぅ”, “e”, and “ぉ” in order of increasing number of times of pressing. Further, when the “1” key is pressed 11 times or more, the basic character string returns to “A”, and 10 characters “A” to “ぉ” are repeated in the order of increasing the number of presses.

  As shown in FIG. 2, when the key “1” is pressed once, only “A” is a candidate character string. This is because there is no case of other character strings because it is pressed only once. On the other hand, when the “1” key is pressed twice, “ah” and “i” become candidate character strings. This is because “oh” and “i” are considered as possibilities of the character string that the operator tried to input. For example, if the operator presses twice consecutively, the operator tried to input “Oh”, but forgot to move the input position next after inputting the first “A”, and again The case where it is going to input "A" is considered. Similarly, when the “1” key is pressed three times, “Ah”, “Ai”, “Ia” and “U” become candidate character strings. As described above, the candidate display field 103 describes character strings that the operator may have tried to input when the same key is pressed continuously.

  The prediction conversion candidate storage unit 12 stores prediction conversion candidates corresponding to each character string. A predictive conversion candidate is a word that starts with a character string of a certain hiragana character. The predictive conversion candidate only needs to have the first reading that matches the character string, and may have the same number of hiragana characters as the character string when read, or may have more hiragana characters than the character string. For example, the prediction conversion candidate storage unit 12 stores “love”, “as usual”, “item”, “idol”, “nickname”, and the like as prediction conversion candidates starting with “ai”. The predictive conversion candidate storage unit 12 first stores conversion candidates that are frequently used statistically for each character string. And the prediction conversion candidate memory | storage part 12 learns the conversion which the operator used, and adds and memorize | stores it as a prediction conversion candidate.

  The input control unit 2 has a character input control unit 21. The input control unit 2 receives inputs from 10 keys, a confirmation button, a selection key, and a selection button corresponding to each screen area.

  When the selection button corresponding to the character string input area is pressed, the input control unit 2 accepts an operation for the character input area. The operation on the character input area is, for example, input of a character string from the 10 keys, input character string confirmation instruction from the confirmation button, or the like.

  Further, when the selection button corresponding to the candidate character string display area is pressed, the input control unit 2 accepts an operation for the candidate character string display area. The operation for the candidate character string display area is, for example, selection of a candidate character string from among the candidate character strings displayed in the candidate character string display area.

  Further, when the selection button corresponding to the prediction conversion candidate display area is pressed, the input control unit 2 accepts an operation on the prediction conversion candidate display area. The operation on the prediction conversion candidate display area is, for example, selection of a prediction conversion candidate from the prediction conversion candidates displayed in the prediction conversion candidate display area.

  In this way, when a selection button corresponding to a certain display area is pressed, accepting an operation for the area may be referred to as “activating the area”.

  The character input control unit 21 acquires information on the 10-key operation by the operator from the input control unit 2. Specifically, the character input control unit 21 acquires the type of key pressed by the operator and the number of times the same key has been pressed continuously. Hereinafter, the number of times the same key is continuously pressed is simply referred to as “the number of times the key is continuously pressed”. Then, the character input control unit 21 outputs the type of key pressed by the operator and the number of continuous presses to the character candidate acquisition unit 3. Further, the character input control unit 21 searches the candidate table stored in the candidate table storage unit 11 using the type of key pressed by the operator and the number of times of continuous pressing. And the character input control part 21 acquires the basic character string corresponding to the kind of key which the operator pressed down, and the frequency | count of continuous pressing from a candidate table. Then, the character input control unit 21 outputs a character string display command to the character display control unit 51, which will be described later, together with the acquired basic character string information. For example, when the operator presses the “1” key three times in succession, the character input control unit 21 obtains the character candidate information about the “1” key and the information indicating that the number of consecutive presses is three times. Output to part 3. Further, the character input control unit 21 acquires “u”, which is a basic character string when the key is “1” and the number of consecutive presses is 3, from the candidate table. Then, the character input control unit 21 outputs a display command for “u”, which is the acquired character string, to the character display control unit 51.

  In addition, when there is an undefined character string among the character strings displayed on the character display control unit 51, the character input control unit 21 outputs the undefined character string to the prediction conversion candidate acquisition unit 4. . On the other hand, when all the character strings displayed on the character input control unit 21 have been confirmed, a character string having a predetermined number of characters at the end of the character string displayed on the character input control unit 21. Is output to the predictive conversion candidate acquisition unit 4.

  The operator selects one candidate character string from the candidate character strings displayed on the candidate display control unit 52 using the selection key. Hereinafter, the candidate character string selected by the operator may be referred to as “selection candidate character string”. In this case, the character input control unit 21 acquires a selection candidate character string using the selection key by the operator received by the input control unit 2. Then, the character input control unit 21 outputs the received display command for the selection candidate character string to the character display control unit 51. Further, the character input control unit 21 outputs the received selection candidate character string to the prediction conversion candidate acquisition unit 4. Further, the character input control unit 21 outputs the received selection candidate character string to the character candidate acquisition unit 3.

  In addition, the operator selects one prediction conversion candidate from the prediction conversion candidates displayed on the prediction conversion candidate display control unit 53 using the selection key. Hereinafter, the predictive conversion candidate selected by the operator may be referred to as a “selected predictive conversion candidate”. In this case, the character input control unit 21 acquires the selection prediction conversion candidate received by the input control unit 2. Then, the character input control unit 21 outputs a display command for the selection prediction conversion candidate to the character display control unit 51. Then, the character input control unit 21 determines the selected predictive conversion candidate as the input character string, and moves the character input position to the next place. Further, the character input control unit 21 outputs a notification to the effect that the prediction conversion candidate has been selected to the character candidate acquisition unit 3. Furthermore, the character input control unit 21 outputs a character string having a predetermined number of characters at the end of the character string to the prediction conversion candidate acquisition unit 4 together with a notification that the prediction conversion candidate has been selected.

  Further, the operator inputs an instruction to confirm the character string displayed on the character display control unit 51 as an input character string using the confirm button. In this case, the character input control unit 21 acquires an input character string confirmation instruction using the confirmation button by the operator received by the input control unit 2. Then, the character input control unit 21 determines the character string displayed by the character display control unit 51 as the input character string, and moves the character input position to the next place. In addition, the character input control unit 21 outputs an instruction to confirm the selection candidate character string as the input character string to the character candidate acquisition unit 3.

  The character candidate acquisition unit 3 receives from the character input control unit 21 the input of the type of key pressed by the operator and the number of continuous presses. Further, the character candidate acquisition unit 3 receives input of the candidate character string currently displayed on the display unit from the character input control unit 21 by the character display control unit 51. Here, the candidate character string currently displayed on the display unit by the character display control unit 51 is a basic character string as long as the operator has input a character by pressing the 10 key. If one of the character strings is selected, it is a selected character string. And the character candidate acquisition part 3 searches the candidate table memorize | stored in the candidate table memory | storage part 11, using the kind of key pressed by the operator, and the input of the number of continuous presses. Then, the character candidate acquisition unit 3 acquires all candidate character strings corresponding to the type of key pressed by the operator and the number of continuous presses from the candidate table. Here, the candidate character string acquired by the character candidate acquisition unit 3 includes a basic character string. Then, the character candidate acquisition unit 3 outputs a character string display command to the candidate display control unit 52 described later together with information on the candidate character string obtained by removing the candidate character string currently displayed on the display unit from the acquired candidate character string. To do.

  The character candidate acquisition unit 3 receives an input from the input control unit 2 for confirming the selected selection candidate character string as an input character string. When receiving a confirmation instruction, the character candidate acquisition unit 3 outputs an instruction to delete the display of the candidate character string to the candidate display control unit 52.

  When there is an undefined character string at the end of the character string displayed on the display unit by the character display control unit 51, the predictive conversion candidate acquisition unit 4 inputs the undefined character string to the character input control unit 21. Receive from. The predictive conversion candidate acquisition unit 4 or the end of the character string displayed on the display unit by the character display control unit 51 such as when one of the predictive conversion candidates is selected has been determined. An input of a character string having a predetermined number of characters is received from the character input control unit 21. Then, the prediction conversion candidate acquisition unit 4 acquires a prediction conversion candidate group corresponding to the received character string from the prediction conversion candidate storage unit 12. Then, the predicted conversion candidate acquisition unit 4 outputs the acquired predicted conversion candidate group to the predicted conversion candidate display control unit 53 together with the display command.

  The display control unit 5 includes a character display control unit 51, a candidate display control unit 52, and a predictive conversion candidate display control unit 53.

  The character display control unit 51 receives from the character input control unit 21 a display command for a basic character string input by the operator. And the character display control part 51 displays the received basic character string on a display part after the character string already displayed on the display part. When all the character strings already displayed on the display unit are confirmed, the display unit displays the mark indicating that the character string is not confirmed only on the newly received basic character string. On the other hand, when there is a character string that has not been confirmed yet at the end of the character string that is already displayed on the display unit, the character display control unit 51 displays the received basic character string in the character string that has not yet been confirmed. In addition, it is displayed on the display unit so as to add a mark indicating that they are not fixed.

  The character display control unit 51 receives a display command of the selection candidate character string selected by the operator from the character input control unit 21. And the character display control part 51 changes the character string of the part corresponding to a selection candidate character string, ie, the basic character string corresponding to a selection candidate character string, or another candidate character string, and changes the received selection candidate character string. Display on the display. When all the other character strings already displayed on the display unit are confirmed, the display unit displays the mark indicating that the selected candidate character string is not confirmed. On the other hand, when there is a character string that has not yet been confirmed at the end of another character string that is already displayed on the display unit, the character display control unit 51 selects a candidate character string as a character string that has not yet been confirmed. Is displayed on the display unit so as to add a mark indicating that the part is not fixed to the part to which the mark is added.

  In addition, the character display control unit 51 receives an input from the character display control unit 51 of a display command of the selection prediction conversion candidate selected by the operator. Then, when there is an unfixed character string at the end of the character string currently displayed on the display unit, the character display control unit 51 displays the received selected prediction conversion candidate instead of the undefined character string. Display on the screen. When all the character strings currently displayed on the display unit are confirmed, the character display control unit 51 displays the selected prediction conversion candidate received after the character string currently displayed on the display unit. Let

  The candidate display control unit 52 receives a candidate character string display command from the character candidate acquisition unit 3. Then, the candidate display control unit 52 displays the received candidate character string on the display unit. Here, the candidate display control unit 52 displays the candidate character string on the display unit so that the operator can select one candidate character string from among the candidate character strings displayed using the selection key. Specifically, when the operator operates the selection key, the candidate display control unit 52 adds a mark for selecting the displayed candidate character string to the candidate character string selected by the operator. To display.

  The prediction conversion candidate display control unit 53 receives a prediction conversion candidate display command from the prediction conversion candidate acquisition unit 4. And the prediction conversion candidate display control part 53 displays the received prediction conversion candidate on a display part. Here, the predictive conversion candidate display control unit 53 causes the display unit to display one candidate character string from among the candidate character strings displayed using the selection key. Specifically, when the operator operates the selection key, the predictive conversion candidate display control unit 53 adds a mark for selecting the displayed predictive conversion candidate to the predictive conversion candidate selected by the operator. Display on the display.

  FIG. 3A is a diagram illustrating an example of display on the display unit of an input character string, a candidate character string, and a predictive conversion candidate. The display unit according to the present embodiment is, for example, a liquid crystal screen of a mobile phone. Here, the display area of the input character string, the candidate character string, and the prediction conversion candidate will be described with reference to FIG.

  An area 201 is an input character string display area. The character display control unit 51 displays a character string in the area 201 on the display unit.

  An area 202 is a candidate character string display area. The candidate display control unit 52 displays the candidate character string in the area 202 on the display unit.

  An area 203 is a display area for predictive conversion candidates. The prediction conversion candidate display control unit 53 causes the display unit to display the prediction conversion candidate in the area 203.

  Conventionally, in a mobile phone or the like, an input character string display area and a prediction conversion candidate display area are arranged in the longitudinal direction of the display unit, that is, in the vertical direction toward the paper surface in FIG. Therefore, as shown in FIG. 3A, the conventional operation feeling is maintained by arranging the display area of the input character string, the display area of the candidate character string, and the display area of the prediction conversion candidate in the longitudinal direction of the display unit. Can do. Therefore, even if a candidate character string display area is newly added as in this embodiment, the operator's uncomfortable feeling can be reduced.

  In this embodiment, as an example, as shown in FIG. 3A, the input character string display area, the candidate character string display area, and the prediction conversion candidate display area are arranged in the longitudinal direction of the display unit, that is, on the paper surface. However, the arrangement method of the display areas is not limited to this.

  FIGS. 3-2 and 3-3 are diagrams illustrating other examples of display of the input character string, the candidate character string, and the prediction conversion candidate on the display unit.

  For example, as shown in FIG. 3-2, a region 202 that is a candidate character string display region is provided in a region 201 that is a display region of an input character string, and further, a prediction conversion candidate candidate is displayed downward toward the page of the region 201. You may arrange | position each area | region so that the area | region 203 which is a display area may be provided. In FIG. 3B, the area 202 is displayed as a balloon from the input character string before the confirmation of the area 201 corresponding to the candidate character string. Thereby, the operator can easily grasp which input character string corresponds to the displayed candidate character string.

  Also, for example, as shown in FIG. 3C, the lower part of the area 201 that is the display area of the input character string toward the paper surface is divided in the left-right direction toward the paper surface, and is a candidate character string display area. An area 202 and an area 203 that is a display area for predictive conversion candidates may be arranged.

  Next, with reference to FIG. 4, an overall operation when inputting characters using the mobile phone according to the present embodiment will be described. FIG. 4 is a diagram illustrating an example of the transition of the display screen when inputting characters in the mobile phone according to the first embodiment.

  FIG. 4 shows the transition of the display screen when characters are input. Specifically, the display screen changes in the order of the display screen 301, the display screen 302, the display screen 303, and the display screen 304. A display area 311 in FIG. 4 is a character input display area. The display area 312 is a candidate character string display area. The display area 313 is a prediction conversion candidate display area. In FIG. 4, only the display areas of the display screen 301 are labeled for convenience, but in the following description, the display areas of the other display screens 302 to 304 are also described as display areas 311 to 313.

  Furthermore, a button 401 in FIG. 4 is a selection button corresponding to the character input display area. That is, when the operator presses the button 401, the character input display area of the display area 311 becomes active. A button 402 is a selection button corresponding to the candidate character string display area. That is, when the operator presses the button 402, the candidate character string display area in the display area 312 becomes active. A button 403 is a selection button corresponding to the prediction conversion candidate display area. That is, when the operator presses the button 403, the prediction conversion candidate display area in the display area 313 becomes active.

  Here, a case where the key “1” is pressed down three times by the operator will be described. When the operator presses the “1” key three times in succession, the display shown on the display screen 301 is displayed on the display unit. That is, the character display control unit 51 receives an input from the character input control unit 21 and displays “u”, which is a basic character string when the “1” key is pressed three times in succession, in the display area 311. Let Further, the prediction conversion candidate display control unit 53 causes the display area 312 to display the prediction conversion candidate corresponding to “U” received from the prediction conversion candidate acquisition unit 4. Further, the candidate display control unit 52 causes the display area 313 to display a candidate character string when the “1” key received from the character candidate acquisition unit 3 is pressed three times in succession.

  When the operator presses the button 403 in the state of the display screen 301, the input control unit 2 activates the display area 313. Then, the operator uses the selection button to select a candidate character string from among the candidate character strings displayed in the display area 313. Upon receiving the selection, the input control unit 2 instructs the candidate display control unit 52 to move the mark indicating selection to the selected candidate character string. When the operator selects a candidate character string “Ai”, the candidate display control unit 52 adds a mark indicating selection to “Ai” as shown in the display screen 302 and displays it in the display area 313. In the present embodiment, the grayed out portion of the display area 313 on the display screen 302 is a mark indicating selection.

  When the confirm button is pressed by the operator in the state of the display screen 302, the character input control unit 21 instructs the character display control unit 51 to display “ai” in the display area 311 instead of “u”. . In response to the instruction from the character input control unit 21, the character display control unit 51 changes the display of the display area 311 from “U” to “Ai” like the display screen 303. At this time, the prediction conversion candidate acquisition unit 4 acquires the prediction conversion candidate corresponding to “Ai” from the prediction conversion candidate storage unit 12. Then, the predictive conversion candidate display control unit 53 causes the display area 312 to display the predictive conversion candidate corresponding to “Ai” received from the predictive conversion candidate acquisition unit 4 like the display screen 303. At this time, the candidate display control unit 52 receives from the character candidate acquisition unit 3 a candidate character string obtained by removing “ai” from the “u” candidate character string. Then, the candidate display control unit 52 causes the display area 313 to display candidate character strings obtained by removing “ai” from the “u” candidate character strings as in the display screen 303. Further, when the operator presses the button 402, the input control unit 2 activates the display area 312. Then, the operator selects one prediction conversion candidate from the prediction conversion candidates displayed in the display area 312 using the selection button. Upon receiving the selection, the input control unit 2 instructs the prediction conversion candidate display control unit 53 to move the mark indicating selection to the selected candidate character string. When the operator selects the prediction conversion candidate “partner”, the prediction conversion candidate display control unit 53 adds a mark indicating selection to “partner” as shown in the display screen 303 and displays it in the display area 312. In the present embodiment, the grayed out portion of the display area 312 on the display screen 303 is a mark indicating selection.

  When the confirmation button is pressed by the operator in the state of the display screen 303, the character input control unit 21 instructs the character display control unit 51 to display “partner” in the display area 311 instead of “Ai”. . In response to the instruction from the character input control unit 21, the character display control unit 51 changes the display of the display area 311 from “Ai” to “Partner” like the display screen 304. At this time, the prediction conversion candidate acquisition unit 4 acquires the prediction conversion candidate corresponding to the confirmed “partner” from the prediction conversion candidate storage unit 12. Then, the prediction conversion candidate display control unit 53 causes the display region 312 to display the prediction conversion candidate corresponding to the “partner” received from the prediction conversion candidate acquisition unit 4 as in the display screen 304. At this time, the candidate display control unit 52 receives the input character string confirmation information from the input control unit 2. Then, the candidate display control unit 52 deletes all candidate character strings from the display area 313 as in the display screen 304.
