Description

Character input method {CHARACTER INPUT METHOD}

The present invention relates to a character input method for a personal mobile communication device, a telephone, a wired / wireless terminal, and the like, and more particularly, to a character input method for a communication terminal that enables a user to easily execute a character input by a simple key operation.

Recently, as the communication technology is developed, a mobile communication device that enables an individual to make a call while moving is also developed and widely used. In particular, as the mobile communication device is converted from the conventional analog method to the digital method, the user can transmit and receive data such as text as well as voice. Therefore, in recent mobile communication terminals, a character input function is employed so that a user can input necessary characters. Such a character input function is widely applied to general communication terminals in addition to the mobile communication terminals.

By the way, such a terminal has a limited number of keys for inputting characters, so that a large number of characters can be input by the number of key presses or a combination of keys.

1 is a view of a keypad and a display device showing a conventional character input method.

Korean Patent Publication No. 10-0276498 discloses a character input device for a communication terminal.

The character input device disclosed in Korean Patent Publication No. 10-0276498 is for inputting a dial number. The character input device includes a 10-key 61 included in the keypad 60 and numbers and letters corresponding to operation keys input by a user. And a display device 50 for displaying and a cursor moving key 62 for moving the cursor 51 displayed on the display device 50, wherein the 10-key 61 has at least one operation key. At least one letter element is displayed on the top, bottom, left, and right sides of the numeral display on the center, and a first operation key (direction key) having respective direction indications indicating up, down, left, and right directions is provided. . Then, the input character element is determined according to the 10-key 61, the cursor movement key 51, and the direction indication input, and the combination of the determined character elements is displayed on the display device 50, but the display device 50 is displayed. An operation key display area 52 is provided on one side of the upper part to output characters of the input key itself, and a character according to the combination of the 10-key 61 and the first operation key is output on the cursor 51.

In this method, the character to be input can be inputted only two times by a combination of the 10-key 61 and the first operation key (direction key), thereby reducing the number of key presses of the user. And, there is an advantage that can be used to assign a plurality of characters at least four times the key to each key.

However, such a method may be input only after the user recognizes which letters are arranged above, below, left, and right of each key. For example, to enter "ㅓ", you need to know that the key containing "ㅓ" is "7" and to know that "ㅓ" is located above the "7" key. In addition to knowing which character is assigned to each key, there is also a problem of knowing the position of the letter assigned to each key.

In other words, the letters assigned to each key up, down, left, and right are inputted by the combination of the direction keys, and since the character assigned to the up, down, left, and right keys and the direction keys are inconsistent, the user can determine which position the specific letter is assigned to. There is a problem that must be recognized.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a character input method in which a user can easily input a vowel.

It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic block diagram of a wireless terminal according to an embodiment of the present invention, Figure 3 is a view showing the arrangement of the keypad for vowel input according to an embodiment of the present invention.

First, referring to FIG. 2, a wireless terminal according to an embodiment of the present invention will be described. The control unit 100 controls the overall operation of the mobile communication terminal, and performs call and phone number editing, mail transmission and reception, etc. according to a user's request. Performs a control operation for controlling the operation for receiving a consonant or a vowel according to an embodiment of the present invention.

The display unit 120 may be configured as an LCD (Liquid Crystal Display) and the like, and outputs various display data according to the status information and the use mode of the terminal.

The voice processor 130 outputs a digital signal by processing a voice input through a microphone, and converts the data received through the antenna into an analog signal and outputs the analog signal.

The RF unit 140 down-converts and filters the signal received through the antenna and outputs the signal, and up-converts the signal output by modulating the CDMA (CODE DIVISION MULTIPLE ACCESS) from the controller 100. CONVERTING) and filter and transmit to the base station through the antenna.

The memory 150 stores various programs for operating the mobile communication terminal and a plurality of data according to the use of the terminal. In particular, the memory 150 stores a program for receiving a vowel according to an embodiment of the present invention.

As shown in FIG. 3, the key input unit 160 includes a 3x4 basic key 162 and a plurality of function keys (not shown). In particular, the key input unit 160 includes a direction key 161 for vowel input.

As shown in FIG. 3, the key for vowel input according to the embodiment of the present invention is to assign the basic collection "ㅏ", "ㅣ", and "ㅑ" to three specific keys of the 3x4 primary key 162. , Assign "ㅏ" to the "*" key, assign "ㅣ" to the "0" key, and assign "ㅑ" to the "#" key. Then, the specific key to which the default vowel is assigned is pressed, and then by pressing the direction key 161, "ㅗ", "TT", "ㅓ", "ㅏ", "ㅣ", "ㅣ", "ㅡ", " "Ah", "ㅛ", "ㅠ", "ㅕ", "ㅑ" can be entered.

In particular, after the specific key assigned to the basic vowel is pressed, the direction key 161 is pressed to rotate and output the basic vowel assigned to the specific key pressed in the corresponding direction.

This is specifically shown in the table below.

Default Bar Direction Key ㅏ (1) ㅣ (2) ㅑ (3) ▲ ㅗ ㅣ ㅛ ▼ TT ㅣ ㅠ ◀ ㅓ ㅡ ㅕ ▶ ㅏ ㅡ ㅑ

That is, the direction (점, ㅏ) of the captured point and the direction (() of the writing are made to be consistent with the direction key 161.

Hereinafter, the vowel input operation according to the present invention will be described.

First, the controller 100 receives a consonant in a character in a character input mode such as editing a phone number or writing a single message. As shown in FIG. 3, the controller 100 may input a consonant by the number of key presses. Likewise, consonants can be input using the direction keys, and detailed description thereof will be omitted. After the consonant is input, the controller 100 checks whether a specific key to which a basic vowel is assigned is input.

When the specific key is pressed, the controller 100 outputs the basic vowel assigned to the specific key to the display unit 120 and checks whether the up, down, left, and right direction keys 161 are input.

When the direction key 161 is input, the direction key 161 is rotated and output in the direction of the up, down, left, and right direction keys 161 inputted to the basic bar assigned to the selected specific key.

For example, when the user presses the "1" key, the control unit 100 first outputs "ㅏ" to the display unit 120, and then outputs "ㅗ" when the user inputs "▲" among the direction keys 161. If "▼" is input, "TT" is output. If "◀" is input, "ㅓ" is output. If "▶" is input, "ㅏ" is output.

In the case of a double vowel, the same operation as the aforementioned method is performed by inputting a vowel once more, and a detailed description thereof will be omitted.

As described above, the present invention sets the direction key and the vowel shape to be consistent, so that the user does not need to know where the position of the letter assigned to each key is located up, down, left and right as in the prior art. It is easy to type.

In addition, in appearance, the button of the key input unit 160 is complicated in the past, causing visual confusion to the user. However, the present invention provides a visually elegant feeling because only the basic collection is displayed on the basic key 162.

Moreover, although four primary keys have been assigned to input vowels as in the related art, in the present invention, vowels can be input with only three primary keys 162 to add a plurality of different characters to other basic keys 162. There is an advantage to assign.

As described above, the present invention is to store the vowel character by making the direction of the point or handwriting is consistent with the direction key, and to input the vowel according to the input of the user's specific key and direction key 161, The vowel can be easily entered by pressing the direction key in consideration of the captured point or the writing direction.
