Description

Keypad for inputing character on mobile phone or remote controller}

The present invention relates to a character input keypad of a mobile phone or a remote control, and more particularly to a character input keypad capable of quickly and conveniently inputting Korean, English or special characters or symbols on a mobile phone or a remote control.

Recently, as the penetration rate of mobile phones increases, mobile phones are widely used as essential equipment for modern life. The mobile phone can transmit a desired message to the other party's mobile phone by using a short message service (SMS) provided by the mobile phone provider as well as a basic voice call.

Such a message is mainly generated by a user inputting characters written together with numbers on a keypad of a mobile phone. A typical text input method of a typical mobile phone is as follows.

That is, when inputting Hangul, the Hangul basic consonants a, b, b, ㄹ, ㅁ, ㅅ, ㅇ and the basic Korean vowels ㅏ, ㅓ, ㅗ, TT, ㅣ and place a key for inputting 'double consonant' and a key for inputting 'add stroke', a, b When entering basic consonants or basic vowels of, ,, ,, ,, 과 and ㅏ, ㅓ, ㅗ,, ㅣ, press the assigned numeric keys once, and enter, ㅂ, ,, ,, ㅋ, ㅌ, ,, ㅎ or ㅑ, ㅕ, ㅛ, ㅠ, ㅐ, ㅔ, ㅒ, ㅖ is entered by pressing the 'Add stroke' key once or twice to the basic Korean consonants or basic vowels, and ㄲ, ㄸ, ㅃ For the sound of, ㅆ, ㅉ, type a, c, ㅂ, ㅅ, ㅈ, and then press the 'double consonant' key.

In addition, when entering English letters, the English alphabet (A, B, C), (D, E, F), (G, H, I), (J, K, L), (M, N) Assign and place (O), (P, Q, R, S), (T, U, V), (W, X, Y, Z), and press the corresponding numeric key once to assign English letters to the above keys. Letters placed in the first digit of the alphabet (ie A, D, G, J, M, P, T, W), double-click letters placed in the second digit of the English alphabet (ie, B, E, H, K, N, Q, U, X), press three times to place the letter in the third digit of the English alphabet (that is, C, F, I, L, O, S, V, Z); press four times to enter the letter in the fourth digit of the English alphabet. That is, S and Z are inputted.

This is only @,?,! Characters that represent special characters or symbols, such as, are placed separately on the numeric keys that are not assigned to the English alphabet, and in the same way as the above English input method, special characters or symbols placed in the corresponding places according to the number of key presses. It is supposed to be input.

However, the Korean input method or the English or special character or symbol input method as described above, in the case of the Korean input, in order to input the basic consonants or basic vowels of the above-mentioned Hangul, in particular, the corresponding key and the 'add stroke' key It was inconvenient to press several times.

For example, to enter the letter 'Cha', first type the Korean basic consonant 'ㅅ', then press the 'Add Stroke' key two more times to create 'ㅊ', and then again create the default vowel 'ㅏ' Press and press the 'Add Stroke' key one more time to enter 'ㅑ', which causes inconvenience to the user to press the corresponding key five times in order to enter 'cha' which is a simple character.

In addition, this problem is similar to the case of inputting the English, in order to input the corresponding English alphabet, the inconvenience of having to press the key up to four times occurs.

Therefore, the conventional text input method as described above has been inconvenient and cumbersome when entering text due to a large number of inputs. In particular, a hierarchical person (such as an elderly person) who is not familiar with using a mobile phone takes a long time to learn the text. You may be reluctant to type.

On the other hand, digital TVs, such as IPTV (Internet Protocol TV), which converge the Internet and television, can be searched using the EPG (Electronic Program Guide) of the TV with a remote control, or browse the Internet while watching TV, home banking, online. Various contents and additional services provided on the Internet, such as games and home shopping, can be searched using a remote controller. However, there is an urgent need to develop a method for allowing a user to conveniently and quickly input desired characters on the remote controller.

SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems as described above, and provides a configuration of a character input keypad of a mobile phone or a remote controller capable of shortening the number of key presses when entering Korean or English.
