DESCRIPTION OF THE PREFERRED EMBODIMENTS A terminal device, a terminal control method, and a mode for implementing a terminal control program (hereinafter referred to as "embodiments") according to the present application will be described in detail below based on the drawings. Note that this embodiment does not limit the terminal device, terminal control method, and terminal control program according to the present application.

[1. Character input processing]
First, character input processing according to the embodiment will be described using FIG. 1. FIG. 1 is a diagram illustrating an example of character input processing according to an embodiment. Character input processing according to the embodiment is performed by the terminal device 100 shown in FIG. The terminal device 100 is a terminal device such as a wearable terminal or a tablet terminal, and includes a display unit 110 such as a liquid crystal display. The terminal device 100 employs a touch panel, and accepts various operations by touching the display section 110 with a finger or the like. The terminal device 100 according to the embodiment receives character input from the user by displaying an interface for inputting characters according to the area selected by the user. This point will be explained using FIG. 1.

First, in this embodiment, it is assumed that the terminal device 100 is a wristwatch-type terminal device (referred to as a smart watch or the like), which is a type of wearable terminal. Here, it is assumed that the terminal device 100 is switched to a character input mode in which character input is accepted from the user. In such a case, the terminal device 100 displays, on the display unit 110, an input field V1 that displays characters received from the user as input characters, and a cursor C1 that indicates the position at which a character is input in the input field V1.

The terminal device 100 also displays an operation area where the user performs various operations related to character input. Specifically, the terminal device 100 displays an operation area including areas R1 to R11 on the display unit 110.

In the example of (a) in FIG. 1, the terminal device 100 has a first area R1 which is an area used for character input, an area R2 located to the left of the first area R1 for displaying characters, and a first area R1. an area R3 for displaying characters located to the right of , an area R4 for inputting voiced sounds and semi-voiced sounds, an area R5 for inputting lowercase letters, and an area R6 for deleting one character displayed in the input field V1. , an area R7 for inputting blank characters, an area R8 for confirming the characters displayed in the input field V1 as input characters, an area R9 for switching between Japanese input and numerical input, and Japanese input and alphabet input. An operation area including an area R10 for switching between the two candidate character strings and an area R11 related to candidate character strings is displayed. Further, the terminal device 100 initially displays "A" as a representative character in the first region R1, as shown in FIG. 1(a).

In the following, the group of characters included in each line of the Japanese alphabet from the "a" line to the "wa" line will be referred to as an "input character group." Also, the characters in the Japanese alphabet "a" are "a", "ka", "sa", "ta", "na", "ha", "ma", "ya", " "ra" and "wa" are described as "representative characters" of each input character group.

In such a state, when the terminal device 100 receives a swipe operation on the first region R1 from the user, the terminal device 100 selects a representative character of the input character group displayed in the first region R1 according to the direction of the swipe operation. Switch.

For example, assume that the user inputs a swipe operation on the first region R1 where the representative character "a" is displayed. In such a case, the terminal device 100 switches the representative character of the input character group displayed in the first region R1 from "a" to "ka", as shown in FIG. 1(b). Note that the terminal device 100 displays each line in the order of "a", "ka", "sa", "ta", "na", "ha", "ma", "ya", "ra", and "wa". The representative characters may be switched depending on the direction and speed of the flick operation. For example, if the flick operation is slow, the terminal device 100 switches the representative characters to one to three characters (such as "ka", "sa", or "ta" for "a") depending on the speed of the flick operation. In addition, when the flick operation is fast, the terminal device 100 may keep changing the characters repeatedly from "a" to "wa" at a constant speed or gradually decelerate until the user stops. Then, the user operates the terminal device 100 so that the representative character of the input character group including the character desired to be input is displayed in the first region R1 from among the input character groups.

In a state where the representative character of the input character group including the character to be inputted is displayed in the first region R1, when the terminal device 100 receives a long press operation on the first region R1 from the user, the terminal device 100 displays the input character in the first region R1. Characters included in the input character group including the displayed representative character are displayed in a second area centered on the display position of the first area R1.

For example, as shown in FIG. 1(a), assume that the user presses and holds the first region R1 in which the representative character "A" is displayed. In such a case, the terminal device 100 displays the characters included in the "A" line of the Japanese alphabet in a second area centered on the display position of the first area R1, as shown in FIG. 1(c). . At this time, in the second area, the terminal device 100 transfers "A", which is a character in the next row, among the characters included in the input character group "A" line, to the central region R12, and the characters in the next row. A certain "i" is placed in the area R13 on the left side of the area R12, "U", which is the character for the ``u'' stage, is placed in the area R14 above the area R12, and ``e'', the character for the ``e'' position, is placed in the area R15 on the right side of the area R12. Then, the character "o" in the row is displayed in the region R16 below the region R12.

Here, it is assumed that the user continues to press and hold the area R12 where "A" is displayed. In such a case, the terminal device 100 determines "A" displayed in the region R12 as the input character.

On the other hand, in the second area including area R12 to area R16, a swipe operation is input from the area corresponding to "a", and the swipe operation is inputted from the area corresponding to "a", which corresponds to "i", "u", "e", or "o". When the area is selected, the terminal device 100 determines the character selected by the swipe operation as the input character. For example, as shown in FIG. 1(c), if the user inputs a swipe operation from area R12 corresponding to "a" toward area R13 corresponding to "i" in the second area, the swipe operation ``i'' selected by is determined as the input character and displayed in the input field V1.

In this way, the terminal device 100 according to the embodiment switches the representative character displayed in the first region R1 by a swipe operation, and then selects the representative character in the first region R1 by a long-press operation. An input character group including a representative character is displayed in a second area centered on the first area R1, and a character selected by a subsequent long press operation or swipe operation is determined as an input character. Thereby, the terminal device 100 can input characters using less space, and therefore can provide an input interface with high usability.

[2. Terminal device configuration]
Next, the terminal device 100 according to the embodiment will be described using FIG. 2. FIG. 2 is a diagram showing a configuration example of the terminal device 100 according to the embodiment. The terminal device 100 is an information processing device that employs a touch panel, and is, for example, a wearable terminal, a tablet terminal, a notebook PC (Personal Computer), a mobile phone, a PDA (Personal Digital Assistant), or the like. As shown in FIG. 2, the terminal device 100 includes a display section 110, an input section 120, and a control section 130.

The display unit 110 is a display device for displaying each piece of information. For example, the display unit 110 is realized by a liquid crystal display or the like. The input unit 120 is an input device that accepts various operations from the user. Note that since the terminal device 100 according to the embodiment employs a touch panel, the display section 110 and a part of the input section 120 are integrated.

The control unit 130 is configured such that a program (corresponding to an example of a terminal control program) stored in an internal storage device is stored in a RAM (Random Access Memory) or the like by, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). This is achieved by using the internal memory of the computer as a work area.

As shown in FIG. 2, the control unit 130 includes a reception unit 131, a display control unit 132, and an input control unit 133, and realizes or executes information processing functions and operations described below. Note that the internal configuration of the control unit 130 is not limited to the configuration shown in FIG. 2, and may be any other configuration as long as it performs information processing to be described later.

The reception unit 131 receives various operations from the user via the input unit 120. Specifically, the receiving unit 131 performs operations such as specifying characters to be displayed in areas (for example, areas R1 to R16) displayed by the display control unit 132, which will be described later, and confirming the selection of various input candidates. Accepts various user operations (for example, long press operation, swipe operation, flick operation, etc.).

The display control unit 132 displays an operation area where various operations related to character input are performed, and displays predetermined characters in the operation area, in accordance with the operation accepted by the reception unit 131. For example, when the reception unit 131 receives information indicating that the terminal device 100 has been switched to the character input mode, the display control unit 132 displays the first areas R1 to R11 as shown in FIG. 110. The display control section 132 has a representative character display section 132a, a switching section 132b, and a group display 132c.

The representative character display section 132a displays a representative character of any one input character group among the plurality of input character groups in the first region R1.

The input character group is a group of characters included in each line of the Japanese alphabet, such as "a" line, "ka" line, "sa" line, "ta" line, "na" line, and "ha" line. These are character groups included in the line, "ma" line, "ya" line, "ra" line, and "wa" line, respectively. However, alphabets, other languages, numbers, symbols, etc. divided into arbitrary groups may be used as input character groups.

The representative characters are the characters on the next level of the Japanese alphabet in the input character group, such as "a", "ka", "sa", "ta", "na", "ha", and "ma". ”, “ya”, “ra”, or “wa”. For example, the input character group in the "a" line includes the five characters "a", "i", "u", "e", and "o", and the representative character of this input character group is "a". be.

When the first swipe operation is input to the first region R1, the switching unit 132b switches the representative character of the input character group to be displayed in the first region R1 according to the operation direction of the first swipe operation. . The switching unit 132b selects 10 representative characters: "a", "ka", "sa", "ta", "na", "ha", "ma", "ya", "ra", and "wa". Switch in this order. When a swipe operation is input to the left while "A" is displayed in the first region R1, the switching unit 132b changes the character displayed in the first region R1 from "A" to "KA". Switch to . Further, when a swipe operation is input in the right direction while "A" is displayed in the first region R1, the switching unit 132b changes the character displayed in the first region R1 from "A" to "A". Switch to "Wa". Further, the switching unit 132b may increase the number of characters to be switched in the operation direction of the flick operation, depending on the direction and speed of the flick operation. For example, when the speed of the flick operation is below a first threshold, the switching unit 132b switches the representative character displayed in the first region R1 by one character, and when the speed of the flick operation is below a second threshold, the switching unit 132b switches the representative character to be displayed in the first region R1. Two representative characters are switched to be displayed in R1, and when the speed of the flick operation is less than or equal to a third threshold, three representative characters are switched to be displayed in first region R1. Further, when the speed of the flick operation is higher than the third threshold, the switching unit 132b performs control to continue switching the characters in the direction of the flick operation in the first region R1 so that the speed is constant or gradually decelerated. It's okay. Further, the switching unit 132b may control the number of characters to be switched in the operation direction of the flick operation according to the acceleration of the flick operation.

When the first selection operation is input to the first region R1, the group display 132c displays characters included in the input character group including the representative character displayed in the first region R1, centered on the first region R1. It is displayed in the second area. The first selection operation is, for example, a long press operation, but may also be a double tap or the like. The group display 132c displays characters included in the input character group in a second region centered on the first region R1, with characters in the upper row, which are representative characters, in the center, characters in the lower row on the left, and characters in the upper row as the representative characters. Display the text on the top, the text on the right side, and the text on the bottom. In the group display 132c, when the first selection operation is input while "A" is displayed in the first region R1, the character "A" in the other row is displayed in the central region R12, and The character “i” is placed in area R13 on the left side of area R12, the character “u” (u) is placed in area R14 above area R12, and the character “e” (e) is placed on the right side of area R12. In the area R15, the character "O" in a row is displayed in the area R16 below the area R12. However, the manner in which the group display 132c displays characters included in the input character group is not particularly limited. For example, the group display 132c may display five characters "A" to "O" in areas arranged in five directions centered on the first area R1. In this case, any character from "a" to "o" can be selected by a swipe operation instead of the second selection operation.

When a second swipe operation is input following the first selection operation, the input control unit 133 inputs characters located in the direction of the second swipe operation among the characters displayed by the group display 132c. Determine as. In the second area, when a swipe operation is input from region R12 corresponding to "a" to region R13 corresponding to "i", the input control unit 133 inputs "i" located at the swipe operation. Determine as. Furthermore, when a second selection operation is input following the first selection operation, the input control unit 133 determines the representative character as the input character. The second selection operation is, for example, a long press operation, but may also be a double tap or the like. After the group display 132c displays the characters included in the input character group in the second area due to the first selection operation, if the second selection operation is input continuously, the input control unit 133 controls the central "A" displayed in area R12 is determined as the input character.

[3. Character input processing procedure]
Next, character input processing by the terminal device 100 according to the embodiment will be described using FIG. 3. FIG. 3 is a flowchart showing character input processing by the terminal device according to the embodiment.

First, since the terminal device 100 is switched to the character input mode, the representative character display section 132a displays "A" in the first region R1 shown in FIG. 1(a) (step S1).

Subsequently, the display control unit 132 determines whether or not the reception unit 131 performs an operation input to the first region R1 (step S2).

When the display control unit 132 determines that an operation input has been performed on the first region R1 (step S2: Yes), the display control unit 132 determines that the operation input received by the reception unit 131 is a swipe operation (first swipe operation). ) (step S3).

When the display control unit 132 determines that the operation input is a swipe operation (step S3: Yes), the switching unit 132b switches between the first and second switches according to the direction of the swipe operation, as shown in FIG. The representative characters displayed in area R1 are switched (step S4). Thereafter, the process returns to step S2 and continues the process.

In step S3, if the display control unit 132 determines that the operation input is not a swipe operation (step S3: No), the display control unit 132 determines whether the operation input received by the reception unit 131 is a long press operation. (Step S5).

When the display control unit 132 determines that the operation input is a long press operation (step S5: Yes), the group display 132c displays the representative images displayed in the first region R1, as shown in FIG. 1(c). Characters included in the input character group containing characters are displayed (step S6).

Subsequently, the display control unit 132 determines whether the long press operation continues even after the group display 132c displays the characters included in the input character group (step S7).

If the display control unit 132 determines that the long press operation is continued (Step S7: Yes), the input control unit 133 determines the representative character located in the region R12 as the input character (Step S8), and Display it in column V1. Thereafter, the process returns to step S1 and continues the process.

Note that when performing the process in step S1 again, the representative character "A" may be displayed as an initial display in the first area R1, but it may not be displayed before the long press operation in step S5 is input. The selected representative characters may be displayed again.

In step S5, if the display control unit 132 determines that the operation input is not a long press operation (step S5: No), the process returns to step S2 and continues.

In step S7, if the display control unit 132 determines that the long press operation is not continued (step S7: No), the display control unit 132 determines that the swipe operation (second swipe operation) is performed after the long press operation. It is determined whether the input has been made (step S9).

When the display control unit 132 determines that a swipe operation has been input (step S9: Yes), the input control unit 133 determines the character located in the direction of the swipe operation as the input character (step S10), and inputs the input field V1. to be displayed. Thereafter, the process returns to step S1 and continues the process.

In step S9, if the display control unit 132 determines that a swipe operation has not been input (step S9: No), the process returns to step S2 and continues the process.

In step S2, if the display control unit 132 determines that no operation input has been performed for the first region R1 (step S2: No), the display control unit 132 determines that the other regions R2 to R2 other than the first region R1 are It is determined whether an operation input to R11 has been performed (step S11).

If the display control unit 132 determines that an operation input has been performed on another area (step S11: Yes), the display control unit 132 determines whether a confirmation operation has been performed on the area R8 (step S12). .

If the display control unit 132 determines that a confirmation operation has been performed (step S12: Yes), the display control unit 132 confirms the input character and ends the character input.

In step S11, if the display control unit 132 determines that no operation input has been made to other areas (step S11: No), the process returns to step S1 and continues.

In step S12, if the display control unit 132 determines that no confirming operation has been performed (step S12: No), the display control unit 132 executes processing according to the area in which the operation input has been performed. As an example, when an operation input is performed in the region R4, a voiced mark is added to the character located on the left side of the cursor C1. Thereafter, the process returns to step S1 and continues the process.
