Description

Character input method {CHARACTER INPUT METHOD}

The present invention relates to consonant or vowel input, and more particularly, to a consonant or vowel input method that can be used in a mobile communication terminal or a portable information terminal.

In general, most devices, such as a mobile communication terminal or a portable information terminal, have only a number and a minimum function key in order to reduce the size. Consonants or vowels are assigned and used. Typically, three consonants or vowels are assigned to each key, and the consonants or vowels assigned according to the number of key presses are received.

The figure below shows a typical keypad.

For example, to enter a consonant or vowel, press the "5" key once to become "ㅈ", twice to make "zh", and press the third time to "ㅎ". The figure below shows the key values assigned to each problem.

In this case, the number of key presses that the user must press to input one consonant or vowel is twice by 60 (total number of presses) / 30 (number of consonants or vowels) in the arithmetic mean, so that one consonant or vowel There is a problem in that the number of key presses of the user for inputting a number is large.

On the other hand, in such a consonant or vowel input method, since a consonant or a vowel is input by the number of key presses, a predetermined waiting time is set at the time of key input. That is, the controller (see FIG. 1) determines the input consonant or vowel after a predetermined time has passed after the key is input. When the user presses the key "5" once, the character for inputting is not known which is "j", "j", or "ㅎ". This is because “5” must be pressed once more to enter “” and “5” must be pressed twice to enter “”. That is, if there is no key input for a predetermined time after the user's key input, the consonant or vowel to be input by the user is determined by the number of times the corresponding key is pressed. If the waiting time is not set, the input character will always be "ㅈ" regardless of the number of times "5" is pressed.

Therefore, there is a problem in that it takes more time to input consonants or vowels by the set waiting time for each consonant or vowel input.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a method of minimizing the number of key presses of a user when inputting a consonant or a vowel, and shortening the consonant or vowel input time.

2 is a control flowchart for receiving consonants or vowels according to an embodiment of the present invention.

The control unit 100 controls the overall operation of the mobile communication terminal, performs a control operation for calling, editing a phone number, sending and receiving mail, etc. according to a user's request, and receiving consonants or vowels according to an embodiment of the present invention. Control the operation.

The display unit 110 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 consonants or vowels according to an embodiment of the present invention.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to FIGS. 1 and 2.

The following figure shows a schematic configuration of a keypad according to an embodiment of the present invention.

The following figure is an example of Hangul consonants or vowels assigned by key input according to an embodiment of the present invention.

In an embodiment according to the present invention, a first key (number keys 0 to 9) for selecting a consonant or a vowel of a group and a group and a second key for inputting a lower consonant or a vowel of a selected group to receive a Hangul input "*" And "#").

This is summarized in the following table.

First key (group) When "*" is input after the first key input Representative consonants or vowels when only the first key is entered When "#" is entered after the first key input 0 To ｜ ㅖ One ㆍ A N 2 C D Lol 3 M ㅂ ㅌ 4 S ㅇ ㅍ 5 ㅈ H ㅎ 6 ㅏ ㅐ ㅑ 7 ㅓ ㅔ ㅕ 8 ㅡ ㅗ ㅛ 9 TT ㅠ ㅒ

As described above, according to the embodiment of the present invention, since the first and second keys are set to receive consonants or vowels, the average number of key presses that the user must press to input the consonants or vowels is about 50/30 to about 1.67 times. It can be seen that compared to the improvement. By the numerical comparison, there may be no difference in the conventional (two times), but the actual input of 100 consonants or vowels requires the press of 167 times in the embodiment according to the present invention. The difference in the number of presses above occurs.

Hereinafter, a processing flow according to consonant or vowel input will be described with reference to FIG. 2.

In step 300 of FIG. 2, if the controller 100 enters a name of a phone number or selects a text input mode for writing a short message, the controller 100 proceeds to step 310 and checks whether a first key (number keys of 0 to 9) is input. do. When the first key is input from the key input unit 160, the controller proceeds to step 320 and outputs consonants or vowels of the corresponding group according to the input first key, and the representative consonants or vowels are distinguished from other group consonants or vowels. do. The following table shows an example of output of the display unit 120 when the user presses the first key “5” to input “” to input “telson information”.

# ㅎㅎ * #telson

When the second key (*) is input in step 330, the process proceeds to step 340 to search for consonants or vowels according to the first key and the second key (Table 1).

In step 350, the controller 100 outputs the corresponding consonant or vowel “” and proceeds to step 360.

On the other hand, if the second key ("*" or "#") is continuously pressed by the step 330 or 340, the consonants or vowels of the corresponding group according to the first key is toggled and buffered as the key is pressed. In other words, if "*" is pressed twice, "ㅎ" is printed three times, "ㅊ" is pressed three times, and "ㅈ" is printed four times.

If the second key is not input in step 330 and the first key is input again in step 331, the flow proceeds to step 332. For example, if you enter the word "work", the user enters the first key "4" in order to enter the last consonant or vowel "ㄱ" of the first letter "work" and the second letter "work". You have to press this, which is the case. When the user presses "4" to input the "product", the process proceeds to step 332 to search for consonants or vowels according to the first input key, and outputs by step 333.

In step 334, if there is a user's termination request, the process proceeds to step 370, and the entered word or sentence is stored; otherwise, the flow returns to step 330.

After buffering the consonants or vowels in step 333, the process returns to step 320 and outputs the consonants or vowels of the corresponding group, where the output group is based on the first key received in step 331.

As described above, according to the embodiment of the present invention, the consonant or the vowel is determined by the first key or the second key input by the user, and thus compared with the conventional method of determining the consonant or the vowel when a certain time elapses. It can be seen that the input time is reduced.

For example, the flow for entering "telson information" is as follows.

In the above description, the operation according to the Korean input has been described, but it can be applied to other English.

On the other hand, the present invention described above has been described with respect to specific embodiments, of course, various modifications are possible without departing from the scope of the invention. That is, the present invention is not limited to the above-described embodiments and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
