  FIG. 2 is an explanatory diagram showing one display form of the display unit 1. The display unit 1 is a display device that includes an input character display area 11 and an input character selection area 12. In the input character selection area 12, the first character of a character group obtained by grouping a plurality of input characters is displayed as a button. The first character that can identify a character group can also be referred to as a group identification character. The input character display area 11 displays a character selected from the characters belonging to the character group displayed in the input character selection area 12.

  In the example shown in FIG. 2, each character group includes characters in each line of the syllabary 50, and the characters in the upper row of each line as buttons are used as the group identification characters of each character group. Is displayed.

The touch panel 2 is a sensor that detects contact of fingers on the panel and movement of fingers.
For example, when the touch panel 2 detects a finger contact, the control unit 4 specifies a button on the display unit 1 corresponding to the contact position as the selected button. Hereinafter, a position where the touch panel 2 first detects a finger contact is referred to as a contact detection position.

  The control unit 4 controls character input processing. When the touch panel 2 detects a finger contact in the input character selection area 12, the control unit 4 displays a list of characters belonging to the character group corresponding to the button displayed at the contact detection position in the vicinity of the contact detection position. . For example, the control unit 4 may display the list of characters belonging to the character group in a circle on the circumference with the contact detection position as a part of the circumference. The method is not limited. For example, the control unit 4 may display a list of characters belonging to the character group in the vicinity of the contact detection position. In any of the above cases, the position for displaying the list of characters may not include the contact detection position.

  Further, the control unit 4 displays one character belonging to the character group at a predetermined position in the vicinity of the contact detection position (hereinafter referred to as a contact vicinity position). The contact vicinity position may be the same place as the contact detection position or may be different. That is, the control unit 4 may display one character at the contact detection position with the contact detection position as the contact vicinity position.

  FIG. 3 is an explanatory diagram showing an example when the touch panel 2 detects the contact of the finger 20 on the button “A”. In the example illustrated in FIG. 3, when the touch panel 2 detects the contact of the finger 20 on the button “A”, the control unit 4 belongs to the character group “A” with the contact detection position as a part of the circumference. Indicates that a list of characters is displayed on the circumference. In addition, the control unit 4 indicates that the character “A” is displayed at the contact detection position as the contact vicinity position. That is, when the touch panel 2 detects the contact of the finger 20 on the button “A”, the control unit 4 displays the characters “A” of “A” at the contact detection position, and the remaining “I, U, "E, O" is displayed in a circle on the circumference including "A".

  FIG. 4 is an explanatory diagram illustrating an example in which a list of characters included in a character group is displayed vertically in the vicinity of the contact detection position when the touch panel 2 detects the contact of the finger 20 on the button “A”. It is. In the example illustrated in FIG. 4, when the touch panel 2 detects the contact of the finger 20 on the button “A”, the control unit 4 displays a list of characters belonging to the character group “A” near the contact detection position. The group identification character in the group is displayed at the contact detection position.

  In addition, when the touch panel 2 detects the movement of the finger 20 in the input character selection area 12, the control unit 4 moves the input character selection area 12 to one character belonging to the list of characters according to the movement of the finger 20. Are moved in the order of the list so that they are displayed near the contact and the characters are switched. For example, when the touch panel 2 detects the touch of the button and the control unit 4 detects the movement of the finger 20 when the control unit 4 displays the list of characters in a circle, the control unit 4 sequentially switches the list of characters. It is also possible to display a single character at a position near the contact by moving it on the circumference. The method of movement and display is not limited to the above method. For example, when the touch panel 2 detects the movement of the finger 20 when the control unit 4 displays a list of characters vertically, the control unit 4 detects the movement of the character. One character may be switched and displayed in the vicinity of the contact in the order of the list.

  FIG. 5 shows an example in which when the touch panel 2 detects the contact of the finger 20 on the button “A” and displays a list of characters on the circumference, the finger 20 is moved to the left. It is explanatory drawing shown. In the example shown in FIG. 5, when the touch panel 2 detects the contact of the finger 20 on the button “A” and then moves the finger 20 to the left, the control unit 4 displays the characters displayed in a circle. The list of “A, I, U, E, O” is rotated clockwise to indicate that one character “O” is displayed at the contact detection position.

  FIG. 6 is an explanatory diagram illustrating an example in which the touch panel 2 detects the contact of the finger 20 on the button “A” and vertically displays a list of characters 20 and moves the finger 20 downward. It is. In the example illustrated in FIG. 6, when the touch panel 2 detects the touch of the finger 20 on the button “A” and then moves the finger 20 downward, the control unit 4 displays the order of the displayed list of characters. Indicates that the character in the downward direction is selected and displayed at the contact detection position. The control part 4 changes the character displayed on a contact detection position by performing such operations according to the movement of the finger 20.

  In the following description, when the touch panel 2 detects the touch of the finger 20, the control unit 4 displays a list of characters in a circle, and the touch panel 2 detects a left or right movement as a predetermined movement of the finger 20. A case will be described in which a character is rotated clockwise or counterclockwise according to the direction of the operation. However, the predetermined direction of the finger 20 when rotating the character is not limited to the left direction or the right direction, and may be the other direction. For example, it may be an upward direction or a downward direction.

  Further, when the touch panel 2 detects that the finger 20 has left in the input character selection area 12, the control unit 4 determines the character displayed at the position near the contact as the input character and confirms the input.

  FIG. 7 is an explanatory diagram showing an example of the operation when the finger 20 is released in the state shown in FIG. In the example illustrated in FIG. 5, the character “o” is displayed at the contact detection position as a result of rotating the character group. When the finger 20 is released in this state, the control unit 4 determines the character “O” displayed at the contact detection position as the input character. The control unit 4 displays the confirmed character in the input character display area 11 of the display unit 1. FIG. 7 shows an example of this state.

  For example, in the case of a method of assigning one input key “A, I, U, E, O” and changing the assigned character each time the input key is pressed, the character “O” To input, it is necessary to press the input key five times. However, in this embodiment, the character “o” can be input with a single press.

  In the present embodiment, a case will be described in which a character group is associated with lines A to W of the 50 phonogram, but the character group is not limited to cases corresponding to lines A to W of the 50 phonogram. For example, a group of alphabets or numbers may be used as the character group.

  The control unit 4 is realized, for example, by the CPU of the character input device 10 that operates according to a program (character input program). For example, the program may be stored in the storage unit 3 of the character input device 10, and the CPU may read the program and operate as the control unit 4 according to the program.

  Next, the operation will be described. FIG. 8 is a flowchart showing an example of processing until input characters are confirmed. In the following description, as shown in the example of FIG. 2, the character input device 10 performs processing from the state in which the characters in the upper row of each line as buttons are displayed in the input character selection area 12 as group identification characters. The case of starting will be described. Further, the contact vicinity position and the contact detection position are the same position, and the control unit 4 displays the list of characters belonging to the character group in a circle on the circumference with the contact detection position as a part of the circumference. Will be described.

  When the touch panel 2 detects the touch of a finger with respect to the position of the button in the input character selection area 12 (step S1), the control unit 4 displays the characters belonging to the character group corresponding to the button in a circle (step S2, (See FIG. 3). When the touch panel 2 detects that the finger touch is released (YES in step S3), the control unit 4 determines the character displayed at the position near the contact as the input character (step S4), and displays the input character. The character is displayed in the area 11. In the case of the example shown in FIG. 3, since the group identification character is displayed at the position near the contact when the finger touches, the control unit 4 determines the group identification character as the input character.

  On the other hand, when the touch panel 2 does not detect that the finger touch is separated (NO in step S3), the control unit 4 determines whether the touch panel 2 has detected the left or right movement of the finger. Determination is made (step S11). When the control unit 4 determines that the touch panel 2 has detected a leftward or rightward movement of the finger (YES in step S11), the control unit 4 is currently displaying according to the direction in which the finger has moved. A list of characters is rotated and displayed clockwise or counterclockwise (step S12).

  In this example, when the touch panel 2 detects a leftward movement of a finger, the control unit 4 rotates and displays a list of characters clockwise, and when the touchscreen 2 detects a rightward movement of the finger, the control is performed. The case where the part 4 displays the list of characters by rotating them counterclockwise will be described. The display rotation direction with respect to the left or right movement of the finger is not limited to the above direction. For example, the display may be displayed by rotating clockwise with respect to the rightward movement of the finger and rotating counterclockwise with respect to the leftward movement of the finger. In the example shown in FIG. 5, since the finger is slid to the left, the control unit 4 indicates that the character is rotated and displayed in a clockwise direction corresponding to the direction.

  On the other hand, if it is determined that the touch panel 2 has not detected the leftward or rightward movement of the finger (NO in step S11), the processes in and after step S3 for determining whether or not the finger contact is released again are repeated.

  For example, when the user moves the left or right direction so that the user of the input character device 1 moves to the character that the user wants to select, and the control unit 4 moves the character to the contact detection position, the finger is released. The control unit 4 determines the character as an input character (step S4). For example, when the finger is released in the state shown in FIG. 5, as shown in FIG. 7, the control unit 4 determines the character “o” at the contact detection position as the input character and puts the character in the input character display area 11. Display.

  According to the present invention, the control unit 4 displays group identification characters on the display unit 1. When the touch panel 2 detects a finger contact on the group identification character, the control unit 4 causes the display unit 1 to display a list of characters in the character group corresponding to the contact detection position in the vicinity of the contact detection position. One character belonging to the list is displayed near the contact. When the touch panel 2 detects a leftward or rightward movement while the finger is in contact, the control unit 4 moves one character belonging to the character list in the order of the character list to move to a position near the contact. To display. When the touch panel 2 detects that the touched finger has been released, the control unit 4 determines the character displayed at the position near the contact as the input character. Therefore, an operation for selecting a character to be input can be visually confirmed, and a character can be input with a small number of key inputs.

  Next, a modification of this embodiment will be described. In the above embodiment, in the flowchart shown in the example of FIG. 8, when the touch panel 2 does not detect that the finger touch is separated (NO in step S <b> 3), the touch panel 2 moves in the left direction or the right direction of the finger. The case where it is determined whether or not a movement has been detected (step S11) has been described. In the modification of the present embodiment, when the touch panel 2 detects a movement of a finger other than the left direction and the right direction, the control unit 4 displays a list of other character groups in the vicinity of the contact detection position, A case will be described in which one character belonging to the character list is displayed near the contact position. In the following modification, the case where the touch panel 2 detects a downward movement as a movement other than the left direction and the right direction of the finger will be described, but the movement of the finger other than the left direction and the right direction is limited to the downward direction. Not. For example, the movement of the fingers other than the left direction and the right direction may be an upward movement.

  FIG. 9 is a flowchart illustrating an example of processing until an input character is confirmed in a modification of the present embodiment. Processing from when the character input device 10 displays a button in the input character selection area 12 until the touch panel 2 detects a finger touch is the same as steps S1 to S3 (see FIG. 8) in the above embodiment. .

  When the touch panel 2 does not detect that the finger contact has been released (NO in Step S3), the control unit 4 does not detect the left or right movement of the finger (Step S3). No) in S11 will be described. In this case, the control unit 4 determines whether or not the touch panel 2 has detected a downward movement of a finger (step S21). When the control unit 4 determines that the touch panel 2 has detected the downward movement of the finger (YES in step S21), the control unit 4 converts the currently displayed character list into a list of other character groups. Change (step S22).

  The list of other character groups may be, for example, a lower case group or an alphabet, but the list of character groups to be changed is not limited to these contents. FIG. 10 is an explanatory diagram illustrating an example when the touch panel 2 detects a downward movement of a finger from the state illustrated in the example of FIG. 3 in step S21. In this example, it is shown that the control unit 4 has changed the character group in the line A to the character group in the lower line A line and displayed it.

  According to the above method, an operation of selecting a character to be input can be visually confirmed, a character can be input with a small number of key inputs, and a large number of character groups can be assigned even in a limited display space.

  In the above description, when the touch panel 2 detects the left or right movement of the finger, the control unit 4 rotates and displays the display character (step S12), and the touch panel 2 detects the downward movement of the finger. The case where the control unit 4 changes to another character group and displays it (step S22) has been described. The direction of finger movement corresponding to the process of rotating a character and the process of changing to a group of other characters is not limited to the above direction. For example, when the touch panel 2 detects an upward or downward movement of a finger, the control unit 4 rotates and displays a display character, and the touch panel 2 detects a rightward (or leftward) movement of the finger. Sometimes, the control unit 4 may change to another character group and display it.
