  Further, when the user traces his / her finger clockwise without releasing his / her finger from the display 106, “?” Is advanced by one in the display order of the special characters set in advance, as indicated by “516”. ! "Special character is displayed.

  Next, in the state where “!” Is displayed, if the user traces his / her finger up and down without releasing his / her finger from the display 106, the display content does not change.

  Next, FIG. 6 shows a flowchart showing Japanese (Kana character) input processing as a character string input method.

  In step S100, it is determined whether the input mode is Japanese (kana characters), English characters, or numbers / special characters. If it is determined that the input mode is Japanese, the process proceeds to step S102, and the English characters are processed. If it is determined that the character is a number / special character, the process proceeds to step S118.

  This input mode can be switched by pressing a key for switching the mode, for example, the conversion key 108 displayed on the display 106 of the terminal 100 shown in FIG. When the conversion key 108 is pressed, the input mode is switched to English characters, and when the conversion key 108 is pressed again, the input mode is switched to numbers / special characters.

  In step S102, when it is detected that the user presses the display 106 with a finger, “a” is displayed on the display 106 as a character to be displayed initially. For example, as shown in FIG. 10, the kana character “A” is displayed on the upper layer of the application 110 that accepts input of a character string from the user.

  Thereafter, the processing from step S104 to step S114 is continued until the user removes the finger from the display 106, and when the finger is removed, the processing is exited.

  In step S104, when the user's finger tracing operation on the display 106 is detected and the direction in which the belt 104 of the terminal 100 is attached is the vertical direction, it is determined that this operation is an operation in any of the vertical directions.

FIG. 11 illustrates an operation in which the user traces the right circumferential direction without releasing his / her finger from the display 106. Examples of these operations are as described above with reference to FIG. 3 (hereinafter the same).

  In step S108, the vowels of the characters currently displayed on the display 106 are displayed by advancing one by one in the order of “A • ka • sa • tana ...”, and in step S110, the current vowels are displayed on the display 106. Displays the consonant of the current character by advancing in the order of “a, i, u, e, o”.

  In step S112, if the character currently displayed on the display 106 is uppercase, it is converted to lowercase, and if lowercase is displayed, it is converted to uppercase.

  In step S114, if the character currently displayed on the display 106 is not provided with a dakuten / semi-turbid point, a dakuten / semi-turbid point is provided. lose.

  In step S116, English character input processing is performed (details will be described later), and in step S118, numeric / special character input processing is performed (details will be described later).

  In step S120, when the user removes his / her finger from the display 106, the character string currently displayed on the display 106 is determined. After the determination, for example, as shown in FIG. 12, an input is made to the application 110.

  In step S122, it is determined whether or not the next character string is input. If it is determined that the input is performed, the process proceeds to step S100. If it is not determined that the input is performed, the process ends.

  Next, FIG. 7 shows a flowchart showing an English character input process as a character string input method.

  In step S200, it is determined whether the input mode is Japanese (kana characters), English characters, or numbers / special characters. If it is determined that the input mode is Japanese, the process proceeds to step S218 and English characters are processed. If it is determined that the character is a number / special character, the process proceeds to step S216.

  As described above, the input mode is switched every time the conversion 108 is pressed.

  In step S202, when it is detected that the user presses the display 106 with a finger, “A” is displayed on the display 106 as a character to be initially displayed. For example, as shown in FIG. 10, an English letter “A” is displayed instead of “A” in the upper layer of the application 110 that accepts input of a character string from the user.

  Thereafter, the processing from step S204 to step S214 is continued until the user removes the finger from the display 106, and when the finger is removed, the processing is exited.

  In step S204, when the user's finger tracing operation on the display 106 is detected and the direction in which the belt 104 of the terminal 100 is attached is the vertical direction, it is determined that this operation is an operation in any of the vertical directions. Then, the process proceeds to step S212. If it is determined that this operation is an operation in any of the left and right directions, the process proceeds to step S214. If it is determined that this operation is a circular operation, the process proceeds to step S206.

  In step S206, it is determined whether the operation direction of the lap is the right circulatory direction or the left circulatory direction. If it is determined that the circulatory operation direction is the right circulatory direction, the process proceeds to step S208, and the left lap If it is determined that the direction is, the process proceeds to step S210.

  An example of the operation that is determined to be the right circulation direction is as described above with reference to FIG. These operation examples are as described above with reference to FIG. 4 (hereinafter the same).

  In step S208, the English characters currently displayed on the display 106 are advanced by one in alphabetical order, and in step S210, the English characters currently displayed on the display 106 are advanced by one in alphabetical order and displayed. .

  In step S212, if the English character currently displayed on the display 106 is uppercase, it is converted to lowercase, and if lowercase is displayed, it is converted to uppercase.

  In step S214, the English characters currently displayed on the display 106 are displayed in advance in alphabetical order by a predetermined number of characters.

  In step S216, numeric / special character input processing is performed (details will be described later), and in step S118, Japanese character input processing is performed.

  In step S220, when the user removes his / her finger from the display 106, the character string currently displayed on the display 106 is determined. After the determination, for example, as shown in FIG. 12, an input is made to the application 110 (in this process, English characters are input).

  In step S222, it is determined whether or not the next character string is input. If it is determined that the input is performed, the process proceeds to step S200. If it is not determined that the input is performed, the process ends.

  Next, FIG. 8 shows a flowchart showing the input process of numbers and special characters as a method of inputting a character string.

  In step S300, it is determined whether the input mode is Japanese (kana characters), English characters, or numbers / special characters. If it is determined that the input mode is Japanese, the process proceeds to step S312 to process the English characters. If it is determined that the character is a number / special character, the process proceeds to step S <b> 302.

  As described above, the input mode is switched every time the conversion 108 is pressed.

  In step S <b> 302, when it is detected that the user presses the display 106 with a finger, “0” is displayed on the display 106 as a character to be initially displayed. For example, as shown in FIG. 10, a number “0” is displayed instead of “A” in the upper layer of the application 110 that accepts input of a character string from the user.

  Thereafter, the processing from step S304 to step S310 is continued until the user removes his / her finger from the display 106, and when the finger is removed, the processing is exited.

  In step S304, if the user's finger tracing operation on the display 106 is detected and it is determined that this operation is a lap, the process proceeds to step S306.

  In step S306, it is determined whether the operation direction of the lap is the right lap direction or the left lap direction. If it is determined that the lap direction is the right lap direction, the process proceeds to step S308, and the left lap direction is determined. If it is determined that the direction is, the process proceeds to step S310.

  An example of the operation that is determined to be the right circulation direction is as described above with reference to FIG. These operation examples are as described above with reference to FIG. 5 (hereinafter the same).

  In step S308, the numbers and special characters currently displayed on the display 106 are displayed by advancing one by one in numerical order or in a predetermined special character display order. In step S310, the numbers and special characters are currently displayed on the display 106. The numbers and special characters are displayed one by one in the numerical order or in a predetermined special character display order.

  In step S312, Japanese character input processing is performed, and in step S314, English character input processing is performed.

  In step S320, when the user removes his / her finger from the display 106, the character string currently displayed on the display 106 is determined. After the confirmation, for example, as shown in FIG. 12, an input is made to the application 110 (numbers and special characters are inputted in this process).

  In step S322, it is determined whether or not the next character string is input. If it is determined that the input is performed, the process proceeds to step S300. If it is not determined that the input is performed, the process ends.

  Note that the display order of keys indicating functions such as return and space can be determined in advance, and the display of each key can be switched and displayed by a circular operation by the user tracing with a finger.

In this case, in step S300, when the input mode is switched, the conversion key 108 is pressed so that the key related to the function can be input. In terms of processing, according to the flowchart shown in FIG. The special character display order is used as a key display order indicating a predetermined function.
<Modification>

  In the present embodiment, when the operation of tracing the finger on the display 106 performs the orbiting operation and switches the display of the character string, the character string is displayed around the circle drawn by the orbiting operation. It is assumed that the position of the character string to be displayed changes depending on the position of the drawn circle.

  Therefore, as a modification of this embodiment, first, when starting input of a character string, the user performs a circular operation by dragging a finger, and the display position of the character string around a circle drawn by the circular operation After that, when a circular operation is performed by tracing the finger of the user, a character string is displayed at the determined display position.

  For example, as shown in FIG. 13, after starting the application 110 and displaying “Please specify the display position of the character string”, the user performs a round operation by tracing his / her finger and draws by the round operation. The center of the circle is fixed as the display position of the character string.

  At this time, as shown in FIG. 14, by virtually displaying one character string, the user can determine whether or not the display position is appropriate. In this state, the display is performed once. When the user presses 106, the display position is determined. When the display 106 is pressed twice or once, the user performs a circular operation by tracing his / her finger to determine the display position again.

  By adopting such an aspect, the user can once fix the position where the character string is displayed, and can maintain high visibility even if the display is switched by a circular operation thereafter. High usability.

  Although the present embodiment has been described for a small watch-type terminal, the present invention can be applied to any information processing apparatus capable of inputting characters in a touch panel format without being limited to such a mode. It goes without saying that it is possible.

  Further, as shown in FIG. 15, in the portable terminal 600, a character string input area 602 is provided as an alternative to the software keyboard, and the user performs a circular operation or the like by tracing the finger with respect to the character string input area 602. It is also possible to switch the display of the character string so that it can be input.

  As described above, according to the present invention, it is possible for a user to input a character string by drawing a circumference with respect to the display area. Therefore, the user's labor for inputting a character string to a narrow display area is reduced. Can be reduced.

  The program according to the present invention is a program that allows a computer to execute (read) each processing method, and the storage medium according to the present invention stores a program that allows the computer to execute each processing method.

  The program in the present invention may be a program for each processing method of each device.

  As described above, a recording medium that records a program that implements the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU or MPU) of the system or apparatus stores the program stored in the recording medium. It goes without saying that the object of the present invention can also be achieved by performing reading.
