Description

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

  Information processing apparatuses such as smartphones and tablet terminals that use touch panels for character input are rapidly spreading. In connection with this, the improvement of the operativity of the character input using a touch panel is desired. In the following description, information processing apparatuses such as smartphones and tablet terminals that use a touch panel for character input are also simply referred to as information processing apparatuses.

  Unlike hard keys on hardware keyboards used in personal computers, soft keys on software keyboards that use touch panels have no physical boundaries and the keys are small in shape so that multiple characters can be entered quickly. Have difficulty. The software keyboard is an input device including a plurality of soft keys reproduced by software.

  Therefore, in the character input of the information processing device, in order to improve the operability of the user's character input, when a character is selected on the touch panel, the corresponding character string is displayed on the display screen of the information processing device, An input prediction function that accepts selection of a character string is used.

  The information processing apparatus uses the input prediction function to perform input prediction in consideration of the application being used, contexts before and after, time, position information, and the like. Then, the information processing apparatus displays the character string predicted to be input on the display screen, and accepts selection of the character string from the user. Thereby, the user can input a plurality of characters quickly. As described above, the input prediction function is an effective function for improving the operability of character input.

  As another related technique, the display device includes a display unit that displays a key to which a character is assigned, and a touch sensor that detects a position of the contact and outputs a detection result when the contact object comes into contact. Based on the output of the touch sensor, the display device detects the character assigned to the key corresponding to the position of the start point of contact when the contact object touches and the contact position of the contact object is displaced starting from the touched position. It has a control part which performs control which displays a related prediction conversion candidate on a display part. Further, when the touch sensor detects a position corresponding to the prediction conversion candidate while the prediction conversion candidate is displayed, the control unit performs control to select the prediction conversion candidate corresponding to the detected position. At this time, a technique is known in which the control unit controls the display unit so that the prediction conversion candidate is displayed in a region excluding the direction of displacement with the start point as a reference.

  As another related technique, the text input method includes selecting a first set of candidate words stored in a database. The text input method includes displaying on the screen at least one of the first set of candidate words for the user to select. The text input method includes a user generating a continuous input pattern and identifying one or more candidate words located along or in close proximity to the continuous input pattern. The text entry method includes the identified one or more candidate words being entered into a text entry field. The text input method is known to include refreshing displayed candidate words when a continuous input pattern follows a predefined refresh gesture or enters or exits a predefined area. ing.

  Furthermore, as another related technique, the mobile terminal includes a touch panel display and an input prediction publication storage unit that stores input prediction candidates associated with character strings. The mobile terminal also includes a symbol generation unit that refers to the input prediction candidate storage unit based on the character string input from the touch panel display and displays the corresponding input candidate prediction candidate as a symbol with an image around the cursor. Furthermore, when the mobile terminal detects that one object has been selected, a technique including an input control unit that inputs an input prediction candidate included in the object to a cursor is known (for example, Patent Document 1 to Patent Document). 3).

In the information processing apparatus having the character input technique described above, when selecting other than the first displayed character string, the user touches a dedicated key for displaying another character string, and displays the displayed character string. Since the switching operation is performed, the work efficiency of the character input operation may be reduced.
As one aspect, the present invention provides a technique for improving the work efficiency of a character input operation.

  One information processing apparatus disclosed in this specification is an information processing apparatus including a display unit, a detection unit, and a control unit. The display unit displays an image. The detection unit detects a touch. After the touch is detected by the detection unit, the control unit displays a character string that is predicted to be input on the display unit when the touch position is moved in the first direction while the touch is detected. To control. Further, after the control unit displays the character string on the display unit, the touch position is moved in the direction opposite to the first direction in a state where the touch is detected by the detection unit. When moving in the first direction, control is performed to display another character string predicted to be input on the display unit.

[Embodiment]
An information processing apparatus according to an embodiment will be described.
FIG. 1 is a diagram (part 1) illustrating an example of an operation for selecting a character string.
An example of an operation for selecting a character string will be described with reference to FIG.

  As illustrated in FIG. 1A, the information processing apparatus 1 displays the software keyboard 3 on the display unit 30 when the character input process is started. The soft keys on the software keyboard 3 are assigned “a”, “ka”, “sa”, “ta”, “*”, “wa”, “#”, etc., and the assigned characters and Accepts symbol input.

  In the following description, the information processing apparatus 1 is configured such that a detection unit 40 to be described later is arranged on the display unit 30 and can detect which soft key on the software keyboard 3 is touched by the finger of the user 2. And The finger of user 2 is also simply referred to as user 2. Further, the characters and symbols are also simply referred to as characters, and include symbols such as “*” and “#”. The characters displayed on each soft key are also referred to as display characters. When the character displayed on the soft key is touched, the displayed character, character, “A”, “ka”, “sa”, “ta”… “*”, “wa”, and “#” are touched. It is also said.

  As illustrated in FIG. 1A, the information processing apparatus 1 accepts that “TA” is selected by the user 2 when “TA” is touched by the user 2. Then, the information processing apparatus 1 displays a character display 4 indicating that “TA” has been selected by the user 2. In the following description, the character display 4 is a display indicating the character selected by the user 2, and is selected and displayed by displaying the background of the selected character in a dot pattern. In addition, the fact that the character is selected by the user 2 simply means that the character is selected. Furthermore, the fact that the character 2 has been touched by the user 2 simply means that the character has been touched.

  When the position touched by the user 2 moves in the right direction as indicated by an arrow in FIG. 1B, the information processing apparatus 1 is on the moving direction of the touched position in the character display 4. “” Is accepted. At this time, in the character display 4, “te” is selectively displayed as shown in FIG. The movement of the touched position means a slide, a flick operation, and the like. In the following description, the position touched by the user 2 is also referred to as a touch position.

  For example, the information processing apparatus 1 acquires position coordinates indicating a position on the display unit 30 using a touch panel, and obtains a displacement amount of the touch position when the touch position moves. Then, the information processing apparatus 1 determines the selected character according to the touched display character, the direction of displacement of the touch position, and the amount of displacement. At this time, for example, the information processing apparatus 1 stores a reference display character when selecting each character in the setting information 24 to be described later, the moving direction of the touch position, and the displacement amount of the touch position in association with each other. May be.

  The information processing apparatus 1 refers to the setting information 24 and is selected according to the selected display character, the moving direction of the touch position, and the displacement amount of the touch position from the position coordinates of the display character. You may judge the character. In the following description, it is assumed that the information processing apparatus 1 determines a selected character by executing a similar process. However, the determination of the selected character by the information processing apparatus 1 is not limited to this, and arbitrary processing can be used as appropriate.

  As illustrated in FIG. 1A, the information processing apparatus 1 determines the selection of “ta” when a predetermined time has passed in a state where “ta” is selected. In the following description, “to confirm selection” means that even if the position of the touch is subsequently moved, the display character that has received the selection is not changed for a predetermined time.

  In addition, when the touch position moves to the left from the position in FIG. 1A, the information processing apparatus 1 accepts that “Chi” on the moving direction of the touched position has been selected. When the touch position moves upward from the position shown in FIG. 1A, the information processing apparatus 1 accepts that “one” on the movement direction of the touched position is selected. When the touch position moves downward from the position in FIG. 1A, the information processing apparatus 1 accepts that “to” on the moving direction of the touched position is selected. In the following description, accepting that a character has been selected is also simply referred to as a character being selected.

  Then, as shown in FIG. 1C, the information processing apparatus 1 displays a character string display 5 including a character string related to “te” when “te” is selected. Note that the character string display 5 is not limited to a plurality of character strings, and one or more character strings may be displayed.

  When the selection of “ta” is confirmed, the information processing apparatus 1 displays a character string display 5 including a character string related to “ta”. Further, when “Chi” is selected, the information processing apparatus 1 displays a character string display 5 including a character string related to “Chi”. Further, when “T” is selected, the information processing apparatus 1 displays a character string display 5 including a character string related to “T”. Then, when “to” is selected, the information processing apparatus 1 displays a character string display 5 including a character string related to “to”.

  As illustrated in FIG. 1D, the information processing apparatus 1 moves the touch position on the character string display 5 when the character position display 5 is displayed and the touch position further moves to the right. The selection of “weather” in the direction is accepted.

  For example, the information processing apparatus 1 acquires position coordinates indicating a position on the display unit 30 using a touch panel, and obtains a displacement amount of the touch position when the touch position moves. Then, the information processing apparatus 1 determines the selected character according to the selected character, the direction of displacement of the touch position, and the amount of displacement. At this time, for example, the information processing apparatus 1 may store the character, the movement direction of the touch position, and the displacement amount of the touch position in association with the setting information 24 described later.

  Then, the information processing apparatus 1 refers to the setting information 24 and selects the selected character according to the selected character, the moving direction of the touch position, and the displacement amount of the touch position from the position coordinates of the selected character. The determined character string may be determined. In the following description, it is assumed that the information processing apparatus 1 determines a selected character string by executing the same process. However, the determination of the selected character string by the information processing apparatus 1 is not limited to this, and arbitrary processing can be used as appropriate.

  As shown in FIG. 1C, the information processing apparatus 1 moves the touch position on the character string display 5 when the touch position is moved in the upper right direction while the character string display 5 is displayed. The selection of “TV program” in the direction is accepted. Further, as illustrated in FIG. 1C, the information processing apparatus 1 further moves the touch position in the lower right direction in a state where the character string display 5 is displayed. The selection of “text” on the moving direction of the position is accepted. In the following description, selecting a character string displayed on the character string display 5 is also simply referred to as character string selection.

  The information processing apparatus 1 is provided with a dedicated key for character string switching in order to accept from the user 2 selection of a character string other than the character string displayed on the character string display 5. Then, when the dedicated key is touched, the information processing apparatus 1 accepts input of the dedicated key and causes the character string display 5 to display another character string. Thereby, the information processing apparatus 1 has a technique of accepting selection of another character string from the user 2. With this technique, the distance of movement of the finger of the user 2 is increased during a character input operation, and the work efficiency of the character input operation may be reduced.

  Therefore, the information processing apparatus 1 according to the embodiment executes a process of switching selectable character strings to be displayed on the character string display 5 by the user's 2 slide operation. Thereby, the information processing apparatus 1 according to the embodiment facilitates the input of a character string and improves the work efficiency of the character input operation by the user 2.

FIG. 2 is a functional block diagram illustrating an embodiment of the information processing apparatus.
With reference to FIG. 2, the information processing apparatus 1 of the embodiment will be described.

The storage unit 20 stores input information 21, candidate information 22, page information 23, and setting information 24.

  Thereby, the memory | storage part 20 matches and memorize | stores several character strings and the priority of each of several character strings. As the priority, a character string that is more likely to be selected by the user 2 among character strings predicted to be input is set to a higher priority. The priority of the character string is, for example, a rank described later included in the candidate information 22.

  In addition, the storage unit 20 stores a character and a character corresponding to the direction in which the touch position moves from the first region to which the character is assigned, and stores a plurality of character strings corresponding to each character. Store it in association. The first area is, for example, a soft key display area.

  The storage unit 20 stores a plurality of character string groups including one or more character strings and the priorities of the plurality of character string groups in association with each other. The priority of the character string group is, for example, a later-described page included in the candidate information 22. The character string group is, for example, a group of character strings to be described later.

An example of information stored in the storage unit 20 will be specifically described with reference to FIGS.
FIG. 3 is a diagram illustrating an example of input information.
The input information 21 will be described with reference to FIG.
The input information 21 stores an input operation and a character in association with each other.

  In the input operation, information for identifying the input operation of the user 2 is stored. The input operation stores, for example, no movement, left direction, upward direction, right direction, and downward direction. The input operation is not limited to this, and an arbitrary operation may be set as appropriate.

  “No movement” is an input operation in which the touch position is not moved for a predetermined time after the user 2 touches the display character. The left direction is an input operation in which the user 2 touches the display character and then moves the touch position to the left in the touched state. The upward direction is an input operation for moving the touch position upward after the user 2 touches the display character and then touches it. The right direction is an input operation for moving the touch position in the right direction after the user 2 touches the display character and then touches it. The downward direction is an input operation for moving the touch position downward while the user 2 touches the display character and then touches it.

  In the field including no movement, display characters displayed on the soft keys on the software keyboard 3 are stored. The display character is selected when the touch position is not moved for a predetermined time after touching the display character.

  The left field stores a character to be selected when an input operation in the left direction is performed after touching a display character belonging to the same record.

  In the upward field, a character to be selected when an upward input operation is performed after touching a display character belonging to the same record is stored.

  In the field in the right direction, a character to be selected when an input operation in the right direction is performed after touching a display character belonging to the same record is stored.

  The downward field stores a character selected when a downward input operation is performed after touching a display character belonging to the same record.

4 and 5 are diagrams illustrating examples of candidate information.
The candidate information 22 will be described with reference to FIG.
The candidate information 22 stores the selected character, ranking, character string, and page in association with each other.
In the selected character, a character selected by the input operation of the user 2 is stored.

In the rank, the priority of the character string displayed on the character string display 5 is stored. The priority is information for designating a character string to be displayed first when the character string to be displayed on the character string display 5 is switched.
In the character string, a character string that is displayed on the character string display 5 and receives an input operation from the user 2 is stored.

  The page stores an identifier for identifying a group including a plurality of character strings. The page is used as a priority of a group of character strings, for example. Then, the control unit 10 displays the group of character strings on the character string display 5, and when selecting a plurality of character strings at the same time, when switching of the group of selectable character strings is requested, the control unit 10 selects them in order of page numbers The character string group that accepts is switched and displayed on the character string display 5.

A specific example of the candidate information 22 will be described with reference to FIG.
FIG. 5 shows the candidate information 22 corresponding to the characters belonging to the record of the display character “TA” in the input information 21.

In the selected characters, display characters of “ta”, “chi”, “tsu”, “te”, and “to” are stored.
Numbers 1 to 9... Are stored in the ranks. In the example of FIG. 5, it is assumed that the smaller the number, the higher the priority of the associated character string.

Each character string stores a character string corresponding to a display character.
Each page stores a number from 1 to 3... In the example of FIG. 5, it is assumed that character strings associated with the same number of pages are included in the same group. In the example of FIG. 5, it is assumed that the smaller the number, the higher the priority of the group of associated character strings.

  With reference to the candidate information 22, an example of a selectable character string switching process displayed on the character string display 5 by the control unit 10 will be described. In the following description, the case where “ta” is selected will be described, but the switching of selectable character strings is executed by performing the same process when another character is selected.

  When the selection of “ta” is confirmed and an operation for displaying the character string display 5 is accepted, the control unit 10 refers to the candidate information 22 and “typhoon” associated with the priorities 1 to 3 belonging to the page 1. , “Taxi” and “lottery ticket” are displayed on the character string display 5. Further, when an operation for displaying another character string is performed, the control unit 10 refers to the candidate information 22 and associates “tiles”, “who” associated with the priorities 4 to 6 belonging to the page 2. Then, a process of displaying “scouring” on the character string display 5 is executed. Thereafter, the control unit 10 repeats the same process to execute a process of switching and displaying a plurality of character strings. The operation for displaying other character strings will be described later.

FIG. 6 is a diagram illustrating an example of page information.
The page information 23 will be described with reference to FIG.
As shown in FIG. 6A, the page information 23 stores a stage and a page in association with each other.
A character indicating the step is stored in the step. The tier stores dan, dan, dan, dan and dan.

  The page stores an identifier for identifying a group of a plurality of character strings. Then, the page is incremented when the user 2 selects the display character and then the characters in the same row are selected successively. Further, the page is reset when a character at a different stage is selected after the character string display 5 is displayed.

  An example of page increment processing by the control unit 10 will be described with reference to the candidate information 22. In the following description, the case where “te” is selected will be described, but the switching of selectable character strings is executed by performing the same process when another character is selected.

  The control unit 10 selects “te”, refers to the second page 2 of the page information 23 in FIG. 6B, and refers to the character string of page 1 associated with “te” in the candidate information 22 in FIG. “Weather”, “television program”, and “text” included in the group are displayed on the character string display 5. Thereafter, when the position of the touch moves in the “ta” direction, the control unit 10 increments the page corresponding to “te” as shown in FIG. When “te” is further selected in succession, the control unit 10 refers to the second page 2 of the page information 23 in FIG. 6B, and sets “te” in the candidate information 22 in FIG. “Test”, “hand”, and “demo” included in the group of character strings on the associated page 2 are displayed on the character string display 5.

This will be described with reference to FIG.
The display unit 30 displays an image. The detection unit 40 detects a touch. The input / output unit 50 receives input of information from a user or a connected device. Further, the input / output unit 50 outputs information output from the control unit 10 to a connected device.

Referring to FIG. 21, the selection of “ta” corresponding to “no” and no movement is accepted, and the selection of “ta” is confirmed.

  Then, as illustrated in FIG. 9C, the control unit 10 receives the selection with reference to the page information 23 illustrated in FIG. 6A when the touch position is moved in the right direction. Page 1 of the corresponding row is extracted. Then, as shown in FIG. 9C, the control unit 10 displays a character string display 5 including “Ta” in the candidate information 22 and “Taxi”, “Typhoon”, and “Lottery” associated with Page 1. Is displayed on the display unit 30. At this time, the control unit 10 may refer to the candidate information 22 and arrange a character string having a high priority at a position where it can be easily selected and display it on the character string display 5. In the example shown in FIG. 9C, the operation of moving the touch position in the right direction, which is considered to be easier to select than the operation of moving the touch position in the upper right direction and the lower right direction, A character string is arranged in the character string display 5 so that the associated “typhoon” can be selected.

This will be described with reference to FIG.
After displaying the character string on the display unit 30, the control unit 10 moves the touch position in the direction opposite to the first direction while the touch is detected by the detection unit 40. Is controlled to display another character string on the display unit 30 when it moves in the first direction. The other character string may be a character string that has a lower priority than the previously displayed character string and is predicted to be input.

With reference to FIG. 7 and FIG. 8, the above-described processing will be described using processing when “te” is selected.
As shown in FIG. 7D, the control unit 10 accepts that the touch position has moved in the left direction, which is opposite to the movement direction of the touch position in FIG. 7C. Then, as shown in FIG. 6B, the control unit 10 increments the page corresponding to “te”.

  Further, as illustrated in FIG. 8E, when the control unit 10 accepts that the touch position moves to the right, which is the same direction as the touch position moved in FIG. With reference to the page information 23 shown in FIG. 6B, the second page 2 corresponding to “te” that has received the selection is extracted. Then, as shown in FIG. 8E, the control unit 10 displays a character string display 5 including “hand” of the candidate information 22 and “hand”, “test”, and “demo” associated with page 2. Is displayed on the display unit 30.

With reference to FIG. 9 and FIG. 10, the above-described processing will be described using processing when “ta” is selected.
As shown in FIG. 9D, the control unit 10 accepts that the touch position has moved in the left direction, which is opposite to the movement direction of the touch position in FIG. 9C. Then, as shown in FIG. 6C, the control unit 10 increments the next page corresponding to “ta”.

  Furthermore, as illustrated in FIG. 10E, when the control unit 10 accepts that the touch position moves to the right, which is the same direction as the touch position moved in FIG. 9C, With reference to the page information 23 shown in FIG. 6C, the second page 2 corresponding to “ta” that has received the selection is extracted. Then, as shown in FIG. 10 (e), the control unit 10 displays the character string display 5 including “ta” of the candidate information 22 and “tile”, “who”, and “tap” associated with the page 2. Is displayed on the display unit 30.

This will be described with reference to FIG.
The control unit 10 controls the display unit 30 to display character string groups in descending order of priority. The character string group is a group of character strings associated with the same page in the candidate information 22. In addition, the control unit 10 may perform control to display a character string on the display unit 30 in descending order of the associated priority. That is, when displaying the character string which receives selection on the character string display 5, the control part 10 refers to the candidate information 22, and displays a character string in order from a character string with a high priority.

With reference to FIG. 7 and FIG. 8, the above-described processing will be described using processing when “te” is selected.
As shown in FIG. 7C, the control unit 10 displays a group of high-priority character strings in the candidate information 22 and then executes a process of switching the character strings. As shown, in the candidate information 22, a group of character strings having the next highest priority is displayed. The control unit 10 repeatedly executes the above-described processing, thereby displaying a group of character strings having high priority in order on the character string display 5 and accepting selection of the character string.

  For example, when the control unit 10 refers to the candidate information 22 and switches the selectable character strings, the control unit 10 groups character strings related to page 1, character strings group related to page 2, and characters related to page 3. The selectable character strings are switched in the order of the column group, and are displayed on the character string display 5.

This will be described with reference to FIG.

This will be described with reference to FIG.
The control unit 10 displays the character string on the display unit 30 and then moves the touch position to a position to which another character is assigned while the touch is detected by the detection unit 40. When time elapses, the display unit 30 may be controlled to display character strings corresponding to other characters. The second time is a predetermined time and may be stored in the setting information 24. Thereby, since the information processing apparatus 1 displays the character string and continues to accept the character string even if the position of the touch moves to a position to which another character is assigned until a predetermined time elapses. It is possible to prevent erroneous operations and improve the work efficiency of character input operations.

  After the character string is displayed on the display unit 30, the control unit 10 moves the touch position to the first position while the touch is detected by the detection unit 40, and the touch position is the first position. When moving in the direction, another character string predicted to be input may be displayed on the display unit. Thus, after the control unit 10 displays the character string on the display unit 30 and the touch position moves to the first position, the touch position does not pass through the reverse direction and the touch position is subsequently changed. Move in the first direction, another character string predicted to be input is displayed on the display unit 30. Therefore, the information processing apparatus 1 can increase the work efficiency of the character input operation by giving a width to the operation of moving the touch position when switching the character string displayed on the character string display 5.

  When the touch is released, the control unit 10 receives input of the selected character and character string.

A character input process performed by the information processing apparatus 1 according to the embodiment will be described with reference to FIGS. In the following description, it is assumed that the control unit 10 receives an input operation by the touch of the user 2 when the detection of the touch by the detection unit 40 is input.

  The control unit 10 determines whether or not a soft key on the software keyboard 3 has been touched (S101). When the soft key is not touched (No in S101), control unit 10 repeatedly executes the process of S101.

  When the soft key is touched (Yes in S101), the control unit 10 accepts selection of the touched character and determines whether or not a predetermined time has elapsed (S102). When the predetermined time has not elapsed (No in S102), control unit 10 determines whether or not the touch position has moved. Then, when the touch position is not moved (No in S103), the control unit 10 executes the process of S102.

  When the touch position is moved (Yes in S103), the control unit 10 refers to the input information 21 and accepts selection of the touched character and the character in the stage corresponding to the moving direction (S104).

  And the control part 10 determines whether the same stage as the stage selected last time was selected (S105). When a stage different from the previously selected stage is selected (No in S105), control unit 10 resets page information 23 (S106). And the control part 10 performs the process of S107. At this time, the page information 23 is 1 for all the pages as shown in FIG. Note that the control unit 10 may execute the process of S106 when the selection of the stage is accepted for the first time in S104 after the soft key is touched in S101.

  When the same stage as the previously selected stage is selected (Yes in S105), control unit 10 executes the process of S107.

Then, the control unit 10 ends the character input process. The control unit 10 is not limited to S110, and may confirm the input of characters and character strings when the touch is released, and accept the input of characters and character strings selected at that time.

  When the character string is not selected in S108 (No in S108), the control unit 10 determines whether or not the touch position has moved in the opposite direction to the moving walk in S103 (S111). When the touch position has not moved in the reverse direction (No in S111), the control unit 10 executes the process of S109. If the control unit 10 determines that the touch is released in S109 after No in S111, the control unit 10 confirms the input of the character, and the display character corresponding to the soft key touched in S101 is selected in S104. Accepts input of characters corresponding to.

  When the touch position moves in the reverse direction (Yes in S111), the control unit 10 increments the page of the page selected in S104 in the page information 23 (S112). And the control part 10 performs the process of S102. As a result, when the same stage is selected in S104, the control unit 10 refers to the candidate information 22 and the page information 23 in S107, thereby displaying the next highest priority character string group. The processing to be displayed on 30 is performed.

  By executing the processes of S111 and S112, the control unit 10 displays the character string on the display unit 30, and then the touch position is set to the first direction in a state in which the touch is detected by the detection unit 40. It moves in the reverse direction, and further accepts that the touch position has moved in the first direction. Then, after Yes in S105, the control unit 10 controls the display unit to display another character string predicted to be input by executing the process of S107.

This will be described with reference to FIG.

  The control unit 10 determines whether or not the touch position has moved (S116). The movement of the touch position at this time may be in any direction. When the touch position does not move (No in S116), control unit 10 repeatedly executes the process of S116.

  When the touch position is moved (Yes in S116), the control unit 10 executes the process of S117.

This will be described with reference to FIG.
The control unit 10 displays a character string according to the page information 23 (S117). That is, the control unit 10 extracts, from the page information 23, the number of pages corresponding to the stage whose selection has been accepted in S113. Then, the control unit 10 causes the display unit 30 to display a group of character strings corresponding to the extracted number of pages in the candidate information 22. By executing the processing of S101, S102, S116, and S117, the control unit 10 moves the touch position in the first direction while the touch is detected after the touch is detected by the detection unit 40. Then, the display unit 30 is controlled to display a character string predicted to be input.

  The control unit 10 determines whether the touch position has further moved and a character string has been selected (S118). When the character string is selected (Yes in S118), control unit 10 determines whether or not the touch is released (S119). When the touch is not released (No in S119), control unit 10 executes the process of S118.

  When the touch is released (Yes in S119), control unit 10 determines the input of the character and the character string, and accepts the input of the character string selected in S118 (S120). Then, the control unit 10 ends the character input process. Note that the control unit 10 is not limited to S120, and may confirm the input of characters and character strings when the touch is released, and accept the input of characters and character strings selected at that time.

  When the character string is not selected in S118 (No in S118), the control unit 10 determines whether or not the touch position has moved in the opposite direction to the moving walk in S116 (S121). When the touch position has not moved in the reverse direction (No in S121), control unit 10 performs the process of S119. If the control unit 10 determines that the touch is released in S119 after No in S121, the control unit 10 confirms the input of the character, and the display character corresponding to the soft key touched in S101 is selected in S113. Accepts input of characters corresponding to.

  When the touch position moves in the reverse direction (Yes in S121), the control unit 10 increments the page of the page selected in S113 in the page information 23 (S122). And the control part 10 performs the process of S102. As a result, when the selection of the same stage is confirmed in S113, the control unit 10 refers to the candidate information 22 and the page information 23 in S117, thereby selecting a character group having the next highest priority. Processing to be displayed on the display unit 30 is performed.

  By executing the processes of S121 and S122, the control unit 10 displays the character string on the display unit 30, and then the touch position is set to the first direction while the touch is detected by the detection unit 40. It moves in the reverse direction, and further accepts that the touch position has moved in the first direction. Then, after Yes in S114, the control unit 10 performs control to display other character strings predicted to be input on the display unit by executing the process of S117.

  During the character input process, the control unit 10 moves the position of the touch to the position of the soft key to which another character is assigned, and executes a process of S101 when a predetermined time elapses, so that a new software It is determined that there is a key touch.
