Description

Character input method of cellular wireless communication terminal

The present invention relates to a character input of a personal communications service (PCS) terminal or a mobile phone terminal, and more particularly, to display a plurality of character set windows in the form of a keypad on a liquid crystal display and when a character set is displayed. The present invention relates to a character input method of a cellular wireless communication terminal, in which a corresponding character is inputted when an arbitrary button is operated.

In general, a mobile communication system transmits a call message including a unique number of a called terminal through a call control channel of a base station to call a cellular wireless communication terminal to a cellular wireless communication terminal and then receives a call from the terminal. It is supposed to provide.

Such a general cellular wireless communication terminal has a built-in transmitter and a receiver, and allows a two-way call from a long distance by using a radio signal to connect a line between a portable device and a fixed device of a general telephone. Its purpose is to pursue the convenience and mobility of telephone calls.

In particular, the cellular wireless communication terminal has enabled data communication by adopting a digital communication method, and in another aspect, has another purpose to provide various services through such data communication.

To this end, various methods for inputting English, Korean, and special characters, as well as numerals, have been proposed for cellular wireless communication terminals.To realize this, a predetermined character is written in addition to the numbers on the keypad as shown in FIG. 1 or 2. It is supposed to be entered.

A character input method using the keypad shown in FIG. 1 will be described as an example according to the related art.

In the keypad, two or three English alphabets corresponding to the corresponding buttons are written on the numeric buttons, that is, QZ, 2 for ABC, 3 for DEF, 4 for GHI, 5 for JKL, 6 MNO is set to 7, PRS is set to 7, TUV is set to 8, and WXY is set to 9.

In the conventional character input method using the keypad in which English letters are written in the same way, when a number is first input, the number is inputted by dialing a button in which the number is specified in the same way as the number input button of other devices. Lose.

In addition, in the case of inputting a letter, an English letter written in the corresponding button is sequentially input depending on how many times the same number button is continuously operated after switching from a call mode to an input mode by operating a separate function button.

For example, pressing the number button [3] once will display the first letter, D, on the LCD display, pressing [3] two times in succession, E three times in succession, and F will appear. 3 times in succession is displayed.

That is, if you keep pressing [3], D, E, F, 3, D, E ... Appears sequentially on the LCD, and when the desired letter appears, press the navigation key ([*] / [#], etc.) or if a certain time elapses, the current letter is input to the cellular wireless communication terminal and the next letter is input. To move the cursor on the LCD.

The character input method of the cellular wireless communication terminal using the keypad shown in FIG. 2 will be described as another example according to the related art.

The keypad is arranged with the Hangul alphabet according to the Adjacent Touch-Tone Assembly Code for Hangul (ATTACH). The conventional character input method using the ATTACH includes 12 buttons with 12 different signal values. Hangul is inputted by the adjacent button relationship.

For example, to input a, press [1] first, then press [2] next to it, and conversely, press [2] first, then press [1] to enter n.

And, in case of c, it is input diagonally by pressing [1] first and then [5] next.

In other words, the input is set to each of the two adjacent button values of the Korean alphabet written in this manner.

Meanwhile, only the Hangul alphabet is displayed in the accompanying drawings, but letters including exclamation marks or question marks, including the English alphabet, may be displayed between the buttons and the buttons to input 108 character symbols including English as well as Korean.

However, as an example of the character input method according to the prior art described above, it can be seen that Korean characters cannot be input when only numbers and English characters are written together in the keypad.

Therefore, in order to enable the input of Hangul, the number of characters included in one button is increased more than twice, and it is difficult to display all the corresponding characters on a button of a certain size. For example, in order to input Korean characters, the number button [2] should be marked with abc as an example along with ABC. In addition, if a special character is added in addition to the Korean characters, it is more difficult to display the characters on the button.

Meanwhile, another example of the aforementioned character input method according to the related art is that because a letter must be written between the button and the button, when a large number of letters are written, the letters are densely printed around the button, which is aesthetically poor. There is a problem in that it is difficult to mark characters in a size that can be easily identified by a person with it.

Moreover, it is obvious that as the wireless communication technology develops day by day, terminals become smaller and smaller, and since the space between the buttons and the buttons cannot be sufficiently separated according to the miniaturization of the terminal, there are many ways to display characters between buttons. Constraints follow.

In addition, a calculator or an automatic teller machine has 10 numeric buttons and two or more special buttons in the same way as a wireless communication terminal, so it is possible to input Korean characters using the same. If you want to input Hangul, there is a problem that you need to set the Hangul alphabet notation differently according to the relationship between the button and the button.

In summary, the character input method using the ATTACH according to the prior art shows that the characters are displayed between the buttons and the buttons, which impairs the aesthetics of the terminal, limits the scalability of the character input, and is incompatible with other devices that input characters. It is inherent in falling problems.

Therefore, the character input method of the cellular wireless communication terminal which can reduce the number of characters displayed on the keypad as much as possible and can create an effect equal to or higher than the conventional one in the character input speed or the like is preferable.

Accordingly, the present invention excludes the hassle of having to write many characters such as English, Korean, and special characters on the keypad in the above-described prior art, and as one aspect of the present invention, a call function which is a function of a terminal on a keypad It is an object of the present invention to provide a character input method of a cellular wireless communication terminal that enables input of Korean, English, and special characters even if only numbers and a few special characters are written.

In another aspect of the present invention, a plurality of character set windows are displayed in the form of a keypad on a liquid crystal display, and when any character set is displayed, the arbitrary character of the keypad is inputted so that the corresponding characters are inputted to simplify the key operation. The purpose is to improve the character input speed.

In another aspect of the present invention, it is possible to add a variety of special characters to improve the scalability of the character input, as well as to be compatible with other devices for entering the character.

And, there may be a plurality of embodiments of the present invention, hereinafter will be described in detail with respect to the most preferred embodiment.

This preferred embodiment allows for a better understanding of the objects, features and advantages of the present invention.

Hereinafter, exemplary embodiments of a text input method of a cellular wireless communication terminal according to the present invention will be described in detail with reference to the accompanying drawings.

In addition, the technique of the present invention can be applied to various products such as a calculator or an automatic teller machine that can input characters by operating a keypad such as a wireless telephone or a cellular phone.

Thus, FIG. 3 used in the description focuses on various character input devices capable of inputting characters by manipulating a keypad, rather than a specific cellular wireless communication terminal.

However, in the following, an example of using a cell phone is considered to help understand the description.

3 is a front view of a keypad and a liquid crystal display for realizing a character input method of a cellular wireless communication terminal according to the present invention, and FIGS. 4A to 4F are provided for explanation of the cellular wireless communication terminal character input method according to the present invention. It is a figure which shows an Example.

According to the present embodiment, a cellular wireless communication terminal having a keypad 100 and a liquid crystal display 200 is provided; The keypad 100 includes ten numeric buttons 101 each having a terminal number of 1 to 9 and a terminal number of 0, a left-hand button 102 in which ◀ and * are written together, and a right of # and ▶ together. Direction button 103 and... It is composed of the specified function button 104.

In the drawings, reference numerals 201 to 204 denote character set windows displayed on the liquid crystal display 200 according to the operation of the function button 104, where 201 is a first consonant window, 202 is a second consonant window, and 203 is a first window. One vowel window, 204 is the second vowel window.

Here, although the consonant ㅎ is ubiquitous in the first vowel window 203, this is only an example, and instead of ㅎ, the consonant 적은, ㄸ, ㅃ, ㅆ, ㅉ or other consonants may be replaced with other consonants. It's okay.

The character input method according to the present invention in the cellular wireless communication terminal having the keypad and the liquid crystal display configured as described above performs the following operation according to the operation of each button.

Hereinafter, with reference to FIG. 3 and FIG. 4, it demonstrates more concretely.

First, when the user manipulates the function button 104 of the keypad 100 to input a character, it is converted from the call mode to the input mode, and then the Hangul input mode is selected according to the number of operations of the function button 104.

Then, in the Hangul input mode, four character set windows 201 to 204 each consisting of a bundle of nine characters are displayed on the liquid crystal display 200, and the outline of the first consonant window 201 is indicated by a thick line. The second consonant window 202, the first consonant window 203 and the second vowel window 204, which are remaining, are displayed in a thin line and displayed in an inactive state.

In the Hangul input mode as described above, when the user operates the left button 102, the active window is moved to the left, and when the right button 103 is operated, the active window is moved to the right. In particular, when the left button 102 is operated in the active state of the first consonant window 201, the second vowel window 204 is changed to the active state, and conversely, in the active state of the second vowel window 204, the right direction is changed. Manipulating the button 103 changes the first consonant window 201 to an active state.

When the user manipulates any button among the number buttons 1 to 9 to input the consonant or vowel, the consonant or vowel at the same position as the operated button is input in the currently active character set window.

At this time, the consonant windows 201 and 202 and the collection windows 203 and 204 are automatically displayed in an active state every time the input of the vowel and the vowels is minimized, so that the number of button manipulations by the user is minimized. Letters are entered into the cellular wireless communication terminal.

As an example of the character input, a process of inputting the word invention will be described with reference to FIG. 4.

In the initial screen of the Hangul input mode, as described above, since the first consonant window 201 is in an active state (FIG. 4A), when the user presses [8] of the number button 101,, is input, and automatically The first consonant window 201 is changed to the inactive state and the first vowel window 203 is changed to the active state (FIG. 4B).

In this state, when [2] is pressed, ㅏ is input and the first consonant window 201 is activated (FIG. 4C). Then, when [6] is pressed, the letter foot is completed while ㄹ is input, and at the same time, the first vowel window 203 Is activated (FIG. 4D).

Next, since the consonant k must be input first to input the character name, the user presses the left button 102 twice, and the first consonant window 201 is changed to an active state. At this time, even if the right button 103 is pressed twice, the first consonant window 201 is activated in the same manner (FIG. 4E).

Then, press [7] to input ㅁ, and through this process, when the last vowel is entered, the word invention is input to the cellular wireless communication terminal, and the liquid crystal display 200 has the first collection window 203 active. Will remain (Figure 4f).

For reference, □ of the second collection window 204 is used as a space symbol, ■ is used as a back space symbol,, is preferably used as a line break symbol.

According to another embodiment of the present invention, in the input mode, the plurality of character set windows 201 to 204 are alternately displayed at the predetermined time intervals and displayed in an active state.

That is, in the Hangul input mode, the first consonant window 201 and the second consonant window 202 form one pair, and the first vowel window 203 and the second vowel window 204 form another pair, If a consonant is not input even after a predetermined time elapses after the consonant window 201 is activated, the second consonant window 202 is activated, and the consonant is input even after a predetermined time elapses while the second consonant window 202 is activated. If not, the first consonant window 201 is activated, and according to the same process, the first vowel window 203 and the second vowel window 204 are alternately changed into an active state.

For example, in the above-described input process of the present invention, inputting the first consonant window 201 changes to the active state, but it can be seen that the last vowel is omnipresent in the second consonant window 202.

In this state, the user may operate the right button 103 once to activate the second consonant window 202 and then press [3] to input o.

However, even if the user does not operate the right button 103, if the consonant is not input for a predetermined time, the first consonant window 201 is automatically inactivated and the second consonant window 202 is changed to the active state. .

Therefore, when the user waits for a predetermined time after the first consonant window 201 is activated and presses [3] when the second consonant window 202 is automatically activated, the word is invented in the same manner as described above. Is input, but the number of button operations is reduced once.

On the other hand, as a comparative example, unlike the prior art, that is, in addition to the English letters and Hangul in addition to the numbers on the keypad or the various characters between the buttons and buttons, the present invention is a number that enables the call function that is the basic function of the terminal It is possible to input Korean, English and special characters even though only a few special characters are specified.

As a result, according to the present invention, a plurality of character set windows are displayed on the liquid crystal display in the form of a keypad, and when any character set is displayed, the arbitrary character of the keypad is inputted so that the corresponding character is inputted. Various characters can be input in a short time.

According to this application example, there is no need to write English letters and Korean characters together on the keypad, which improves the appearance of the terminal, improves the text input speed, and adds various special characters, thereby improving the scalability of the text input. It can also be applied to other devices, such as calculators for entering text and automatic teller machines.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that various modifications may be made by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

Obviously, from the above description, according to the character input method of the cellular wireless communication terminal according to the present invention, even if only a number and a few special characters are written on the keypad to perform a call function, which is a function of the terminal, the Korean, English and special characters are written. Not only can you input characters, but also the simple operation of the keys improves the text input speed, and has the effect of adding a variety of special characters that can be input.
