Abstract

PURPOSE: A method for inputting characters by using a repetition key in a mobile communication terminal is provided to simplify a character input method while improving the utility by inputting characters with less frequency of pressing keys. CONSTITUTION: In a character input mode, one of input keys is set to be operated as a repetition key(301,302). When a character(including figures and marks) is displayed at a position of a current cursor, the current cursor reads a character displayed at the previous cursor if the repetition key is pressed(303,304,305). The read character is duplicated to be displayed at the current cursor(305,307).

Description

Letter input method using the repetition key in mobile telecommunication terminal}

The present invention relates to a character input method that can increase the simplicity and utilization of the character input method by a small number of key presses during character input using a repeat key (copy key) in a mobile communication terminal.

In the present invention, the text input method is merely an expression in consideration of the user's position, and is based on its display behavior on an actual terminal.

Nowadays, from mobile pagers to cellular phones, personal mobile phones (PCS), IMT-2000 (International Mobile Telecommunication) and UMTS (Universal Mobile Telecommunication Service) based mobile communications in recent years The communication environment is developing at a tremendous speed, and with the development of mobile communication terminals, the search for additional services available through the terminals is actively being developed.

In particular, as mobile communication terminals become more popular and have more functions, the amount of information stored in the terminals increases, and the use rate of short message service (SMS) has expanded to various age groups as well as teenagers and 20s. . In addition, the mail sending and photomail functions are also added, and the usage rate of the text input to the terminal is expected to increase. Accordingly, in order for a user to efficiently and simply use a character input that will be widely used accordingly, a character input method that can be easily input by the user is required.

Nevertheless, in the conventional mobile communication terminal, there is a problem in that the user inputs the button of the keypad several times in order to input characters.

For example, in the case of Korean Patent Registration No. 159191, a method of combining three symbols "-", "ㅣ", and "·" for vowel input is proposed, and the keypad according to the conventional method is shown in FIG. The arrangement of is disclosed.

Referring to FIG. 1, one or more consonants are assigned to each numeric key, and three numeric keys are assigned with a vertical direction key (ㅣ) for inputting a vowel, a male direction key (-), and a key for short and long term determination (·), respectively. do. For example, in order to input "a", the keys "a", "|", and "." Are sequentially selected. The above-described text input method matches the handwritten stroke order of the Korean alphabet and uses a minimum key for vowel input, so that the keypad is highly efficient and easy for the user to learn.

Nevertheless, the above-described character input method inputs one stroke at a time in order to minimize key assignment for vowels, and thus, there is a problem in that keys must be input as many strokes as vowels for vowel input. That is, in order to input "ㅖ", it is necessary to select "占", "占", "ㅣ", and "|" in order to increase the number of key inputs.

As such, in the conventional text input method, Korean or English must be input by pressing the keypad several times one by one. Characters such as symbols, numbers, and figures are entered in the menu one by one. I had to press the keypad twice. In particular, when you want to enter a set of repetitive characters such as "Bang Bap Bap", a key such as "ㅣ", "." At least 5 to 6 times to enter the letter (bread), to enter the whole letter (bread), you have to press the keypad "6 (5) x 5 = 30 (25)", so there is a problem of increasing the number of keys there was. In addition, symbol or pictograph repetition, number repetition also had a problem that a lot of key input.

The present invention has been proposed to solve the above problems, character input to increase the ease and utilization of the character input method by a small number of key presses during character input using a repeat key (copy key) in the mobile communication terminal The purpose is to provide a method.

In accordance with another aspect of the present invention, there is provided a character input method in a mobile communication terminal, comprising: a first step of setting one of a known input key to operate as a repetition key (copy key) in a character input mode; A second step of reading the character displayed at the cursor immediately before the current cursor when the character (including numbers and symbols) is displayed at the position of the current cursor in the character input mode when the repeat key (copy key) is detected; ; And a third step of copying the read character and displaying the read character at a position of a current cursor.

In addition, the present invention provides a character input method in a mobile communication terminal, comprising: a first step of setting, in a character input mode, at least two of the known input keys to be operated as keys for notifying the start and end of a repetition (copy) range; A second step of reading a sentence (including a word) designated by the start key and the end key when displaying a character (including numbers and symbols) at the current cursor position in the character input mode; And a third step of copying the read sentence and displaying the read sentence at the current cursor position.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exemplary configuration diagram of a mobile communication terminal to which the present invention is applied.

The controller 10 of the mobile communication terminal controls the overall operation of the terminal and at the same time controls the text input method according to the present invention. Then, control of various components provided is achieved.

The voice memory 11 stores various voice data.

The memory 12 stores an operation program and a system program of the controller 10, and the operation program and the system program are usually stored in a ROM area included therein and can be erased as necessary. Electrically erasable ROMs include EEPROM and flash memory. The memory 12 also includes a RAM that temporarily stores data generated during execution of various operating programs.

In particular, the memory 12 stores a character input program by a repeat key (copy key) of the present invention. A more detailed description thereof will be described later with reference to FIG. 3.

The key input unit 13 includes a plurality of numeric keys (letter keys), menu keys, and function keys for performing various functions, and outputs key data to the controller 10 by external operations. In particular, the key input unit 13 includes a repetition key (copy key) button and a drag button when a character is input. For example, the position of the repetition key (copy key) button may be defined by a "#" button, The position of the drag button can be set on the existing keypad (0 ~ 9, *, #), such as the "*" button of the existing keypad, and one of the navigation keys, function keys, and side arrow keys can be repeated (copy key), It is obvious that a drag button may be set and a separate key may be added to the terminal. Although the main menu and its submenus can be configured using the menu function as an index, it is preferable to set an existing keypad button or a separate key button to reduce the number of key inputs.

The display unit 14 is a display device such as a liquid crystal display (LCD). The display unit 14 is controlled by the controller 10 to display the state of the mobile communication terminal or the progress of the program. That is, the overall state of the mobile communication terminal and input user information are displayed.

Therefore, the control unit 10 reads out the corresponding character input program from the memory 12 according to the user's character input request by the key input unit 13, and displays the characters input by the user's key operation based on the character input program. Combination is displayed on the display unit 14. That is, the key input unit 13 is a conventional user information input means, and includes a plurality of keys suitable for a mobile communication terminal to be applied, such as a plurality of numeric keys (letter keys) and function keys, and if there is an input of each of the provided keys, By outputting the unique key data corresponding to each input key to the control unit 10, the control unit 10 reads the character input program corresponding to the key input from the memory 12, and based on the character input program. Characters, numbers, symbols, and the like, input through the key input operation of the key input unit 13 are combined and displayed on the display unit 14.

The RF unit 15 is controlled by the controller 10 and converts a signal output from the controller 10 into a radio signal. In addition, the RF unit 15 converts the radio signal received through the antenna into a desired signal and outputs it.

The ring tone generator 16 generates a ring tone through the speaker under the control of the controller 10.

The voice processor 17 modulates the voice signal input from the microphone to convert the voice signal into voice data, demodulates the voice data input from the RF unit 15 and the voice data stored in the voice memory 11 into voice signals. Sound is output through a speaker.

In particular, the repeat key (copy key) of the key input unit 13 according to the present invention is a key for repeating (copying) letters, numbers, symbols, and the like in the text input mode, and repeats using a drag key ( If you do not set the copy range, the character that will be displayed repeatedly on the current cursor when the repeat key (copy key) is pressed is the character displayed on the previous cursor, that is, if the character entered immediately before is a consonant or a vowel. If it is a consonant or a vowel, or if it is a single letter, the letter, number, etc. Accordingly, the control unit 10 recognizes that the repeating key (copy key) is pressed, copies the previously expressed letters, numbers, symbols, and the like and displays them on the display unit 14.

For example, if a sentence of "kana" is entered and a repeat key (copy key) is pressed at this time, "kana" is displayed on the display unit 14. In addition, when the user enters "ㄱㄴㄷ" and presses the repeat key (copy key), "ㄱㄴㄷ" is displayed on the display unit 14. Particularly, in the case of expressing a set of repetitive characters as in the case of "Bang Bap Bap", the method of expressing the first letter "Bap" is the same as the existing "2" key on the keypad "ㅂ" is assigned. To enter a single character (bread) such as, "ㅣ", "·", "ㅇ", you need to enter the key 5 or 6 times, but the remaining characters (the whole bread) are the same set of characters as the first character (bread). ), Press the repeat key (copy key) four times. Therefore, in the expression of "bang bang bang bang", it takes only 9 to 10 times of key input.

On the other hand, you can set the range (word or sentence) to be repeated (drag) using the drag key. For example, "Hey ~ Let's have a cup of tea in our time. I was really sorry last time. I'm sorry to get you up first. If you type in the sentence "Yeah ~" and then "Let's have a cup of tea when it's time", start the copy (repeat) via the side keys or navigation keys to specify the copy (repeat) range. Move the cursor to the character ("right"), hold down the drag key (that is, the start key of the copy range), use the cursor to reach the last character (".") Of the copy (repeat), and repeat When (Copy key) (finally, it becomes the end key of the copy range) is pressed, the sentence " Let's have a cold drink when it is time " is repeated (copyed) and displayed on the display unit 14. So, finally, "Hello ~ Let's have a cup of tea if we have time. Last time I was really sorry. I'm sorry to get up first without contact. Yes ~ Let's have a cup of tea when we have time." This drag key can be especially useful for repeating (copying) a complete word (e.g., goodbye, love, etc.) or a complete sentence.

As described above, the present invention makes it easy to input letters, numbers, symbols, etc. by using a repeat key (copy key) and a drag key.

Then, the character input method using the repeat key will be described with reference to FIG. 3.

3 is a flowchart illustrating a method for inputting a character using a repeat key according to the present invention.

First, in a text input mode such as writing a text message, writing a mail, or creating a schedule (301), if the control unit 10 detects the pressing of a repetition key (copy key) according to a user's key input (304), immediately before Copied letters, numbers, symbols, etc. are copied and displayed on the display unit 14 (305). At this time, if the character entered immediately before is one consonant or vowel, the consonant or vowel is one character, and if it is a single character, the character, other symbol, number, etc., is the symbol and number. Accordingly, the controller 10 recognizes that the repetition key (copy key) is pressed and copies the previously expressed letters, numbers, symbols, etc. and displays them on the display unit 14 (304, 305).

On the other hand, in the state in the text input mode (301), the control unit 10 in response to the user's key input drag (i.e. key to start the copy range) and repeat key (copy key) (i.e., copy) Recognizing the press of a key indicating the end of a range (i.e., if a repeating (copying) range (word or sentence) is specified) (303,306), a word or sentence of the specified range is copied and displayed on the display unit 14. 307.

This process is possible at any time in the text input mode state 301 (302 to 308).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

According to the present invention as described above, the character input method can be simplified even with a small number of key presses when the character is input by using a repeat key (copy key) in the mobile communication terminal. .
