Description

  Embodiments described herein relate generally to a mobile terminal.

  In recent mobile terminals such as mobile phones, character data is often exchanged, such as transmission / reception of e-mails and browsing of websites, and character input is also often performed using mobile phones. However, in consideration of the size of the mobile phone, the number of operation keys for inputting characters needs to be a minimum and convenient number. Therefore, conventionally, when inputting characters, numeric keys and several other keys used for making a call are used.

  There are so-called “kana input methods” and “two-touch input methods” as character input methods for mobile phones. The Kana input method is a method in which Kana characters are assigned to the numeric keys for each line of the Japanese syllabary, and each time the same numeric key is pressed, the letters on the same line of the Japanese syllabary are switched in vowel order . For example, “A line” is assigned to the “1” key, and each time the “1” key is pressed, the characters of “A line” are sequentially switched to “A”, “I”, “U”,. .

  On the other hand, the 2-touch input method is a method of inputting a character corresponding to a two-digit number composed of a first input number and a second input number by pressing a number key twice. The first input number key is assigned a 50-sound row (consonant), such as “1” key is “A row”, “2” key is “Ka row”, etc. The keys are assigned fifty steps (vowels) such that “1” key is “A”, “2” is “I”, and so on. One character corresponding to the obtained two-digit number combination is called from the corresponding character data table held in advance. For example, to input “ku”, press the “2” key (or row) and the “3” key (column) in this order. In the two-touch input method, the number of times the number key is pressed only needs to be twice, so that it is possible to input a character with a smaller number of times of pressing than in the kana input method.

  However, in the 2-touch input method, even if the number key of the consonant pressed first is correct, if the number key of the vowel pressed second is incorrect, as a result, an incorrect character is input. When correcting, it is necessary to delete the wrong character and input again from the first numeric key, and the operation is complicated.

The mobile terminal according to the present embodiment includes an input unit including a correction key for instructing correction of characters, a plurality of number keys for inputting numbers, and a movement key for moving the cursor left and right, and 2 A storage unit that stores characters corresponding to a combination of two pieces of numeric information, and the first numeric information and the second numeric information that are continuously input by the numeric keys of the input unit are referred to the storage unit A search unit that searches for a character corresponding to a combination of the first and second numeric information, a display unit that displays the character searched by the search unit, and an input by the correction key. Is converted into the first and second numeric information, the first numeric information is displayed, and the second numeric information is waited for input. In this state, the numeric key Entered if detected When the character is set as the third numeric information and the input of the movement key in the left direction is detected while waiting for the input of the second numeric information, the second numeric information is displayed and the first numeric information is displayed. In this state, when the input of the numeric key is detected, the entered number is used as third numeric information, and the second numeric information is waited for input or the first numeric information. When the input by the correction key is further detected while waiting for the input of the second numerical information, if the input is waiting for the input of the second numerical information, the value obtained by adding 1 to the second numerical information is set to the third number. Information, and when the first numeric information is waiting to be input, a value obtained by adding 1 to the first numeric information is used as the third numeric information. In any case, the third numeric information is used. And the first or second numerical information that has not been changed And having a correction unit to the numerical information.

Details of these will be described later.

<Example of character input and correction operations>
Next, an operation example of character input and correction of the mobile phone 1 having the above configuration will be described with reference to FIG.

  When the user starts character input using the two-touch input method and first presses the numeric key “2” of the operation key 53, the key operation detection unit 13 detects the press of the numeric key “2”. A code indicating the first number “2” is output to the control unit 10 (step S101). Subsequently, when the user presses the number key “3” for the second time, the key operation detection unit 13 detects the pressing of the number key “3” and sends a code indicating the second number “3” to the control unit 10. Output (step S103). Next, the character acquisition function 101 of the control unit 10 refers to the character table of the character table storage unit 21, and displays a code indicating the first number “2” that is a row number and a second number that is a column number. The character “ku” corresponding to the combination of the two-digit number “23” consisting of the code indicating “3” is acquired, and the number “23” is temporarily stored in the storage unit 16 (step S105). Then, the character “ku” is displayed on the display 52 via the display control unit 12 (step S107).

  Next, when the character correction key of the operation key 53 is pressed by the user, the key operation detection unit 13 detects this pressing (“Yes” in step S109), and the character correction function 102 is displayed on the display 52 in step S107. The displayed character “ku” is set to the character correction state, and the character table in the character table storage unit 21 is referred to and converted to the number (first number) “2” in the row indicating the corresponding consonant “ka line”. Then, it is displayed on the display 52 via the display control unit 12. In addition, the character correction function 102 converts a symbol indicating that the input following the converted “2” is waiting (for example, blinking of an underscore) to the right of “2” displayed on the display 52 after conversion. It is displayed next to it (step S111). At this time, “3” is deleted from the number “23” corresponding to the character “ku” on the display 52, and the display 52 is displayed as waiting for input of another number. The user can recognize that the character can be corrected by viewing the display 52.

  In step S111, when the user further presses the character correction key and the key operation detection unit 13 detects (YES in step S113), the character switching function 103 stores the characters temporarily stored in the storage unit 16 in step S105. From the number combination “23” corresponding to “ku”, the number “4” obtained by adding 1 to the deleted number “3” is input, and the displayed number “2” and the input “4” are input. The character “ke” corresponding to the number “24” in combination with is displayed. That is, it is the same consonant “ka line” as the character “ku” displayed on the display 52 in step S107, and is switched to “ke” next to the character “ku” in the vowel order and displayed on the display 52 (step). S115). That is, since the number in the row corresponding to the character “ku” displayed on the display 52 in step S107 is “2” and the number in the column is “3”, the number “2” in the same row and the number in the column Is switched to the character “ke” corresponding to the combination with the next number “4” and displayed on the display 52. Thereafter, each time the character correction key is pressed, the character switching function 103 sequentially switches the numbers in the column, and the characters “K”, “K”,... Corresponding to the number “2” in the row and the number in the switched column are displayed. Acquired and switched and displayed on the display 52.

  In step S111, when the user presses the numeric key “5” of the operation key 53 and the key operation detection unit 13 detects it (“Yes” in step S117), the character acquisition function 101 receives the input numeric key “5”. Is a column number in the character table in the character table storage unit 21. The character acquisition function 101 includes the row number (first number) “2” indicating the consonant “ka line” displayed in step S111 and the column number “5” input in step S117. The character “ko” corresponding to the combination of the two-digit number “25” is acquired from the character table in the character table storage unit 21 and displayed on the display 52 via the display control unit 12 (step S119).

  Next, when the key operation detection unit 13 depresses the confirmation key of the operation key 53 (“Yes” in step S121), the character confirmation function 104 sets the corrected character “ko” in a confirmed state and temporarily stores it in the storage unit 16. The number “23” corresponding to the written character “ku” is deleted (step S123). Therefore, it is possible to easily correct the character being input.

  When the user moves the cursor on the screen using the movement key of the operation key 53, designates the character that has been confirmed in step S123, and presses the character correction key, the key operation detection unit 13 detects (step The combination of numbers corresponding to the designated character is retrieved from the character table in the character table storage unit 21 and temporarily stored in the storage unit 16. And it returns to the process of character correction after step S111. Therefore, it is possible to easily correct the characters that have been confirmed.
