Description

Apparatus for Inputting Characters where Consonant and Vowel Keys are separately Assigned}

The present invention relates to an input device for inputting a character into a communication terminal, and more particularly to a character input device through the separation and assignment of the letter.

Due to the rapid development of wireless communication systems, communication terminals such as portable telephones and personal digital assistants (PDAs) generally perform functions of sending and receiving short messages and data communications as well as ordinary voice calls. In particular, with the spread of PDAs and smart phones, data storage and transmission functions are generally performed, and various activities such as e-mail transmission and reception using a communication terminal and internet access are being performed.

In order to support such an additional service function, a communication terminal includes a keypad capable of inputting Korean and English, and most communication terminals adopt a method of inputting text using a numeric key for dialing.

Regarding the method of inputting a character, the research on the Hangul input method has been actively conducted until now, various input methods have been commercialized, and the user can input the Hangul without much inconvenience. However, although the necessity of the English input method increases with the increase in the spread of PDAs and smart phones, the research on the English input method is insufficient, and most of them adopt the English input method using the T9 method which is currently standardized.

1 is a plan view illustrating an English input device using a conventional T9 method.

As shown in FIG. 1, in the T9 type English input device, the English alphabets Q and Z are assigned to the first key, the English alphabets are arranged in the order of the keys 2 to 0, and one key is used. Each of the three alphabets is arranged. The alphabet arranged on each key can be entered by pressing the corresponding numeric key, and the second and third alphabet letters arranged on the same key can be entered by pressing the corresponding numeric key twice and three times, respectively. For example, A is input by pressing the number 2 key once, B is input by pressing the number key 2 twice, and C is input by pressing the number key 3 three times.

In the conventional English input method according to the T9 method shown in FIG. 1, since three alphabets are assigned to one key, it takes a long time to input an English letter, and it is inconvenient to enter an English letter because the alphabet is not considered at all. There were many points. For example, J, which has a low frequency of use, is input by pressing a single key, while S, which has a high frequency of use, can be input by pressing a key three times.

As a conventional technique for solving the problem of the T9 method, there is disclosed in the Republic of Korea Patent Publication No. 2000-0044417.

This is to achieve the simplification and speed of the alphabetic character input by separating the consonants and vowels of the alphabet and dividing vowel combinations having a high probability of succession among vowels and vowels in a plurality of keys.

FIG. 2 is a plan view illustrating an English alphabet input device disclosed in Japanese Patent Laid-Open Publication No. 2000-0044417.

As shown in FIG. 2, the vowels of the alphabet are assigned to the numbers 1 to 3 keys located on the keypad, and the consonants of the alphabet are assigned to the fourth to zero keys. In addition, the numbers 1 to 3 keys for inputting the vowels of the alphabet are assigned 'AE, EA, EE', 'IO, OI, OO', 'UY, YU' which are likely to be continuous in the vowels. In other words, press the number 1 key once to enter A, press twice to enter E, press three times to enter EA, and press four times to enter EE.

The conventional alphabetic input device shown in FIG. 2 has an advantage of inputting vowels that are likely to be continuous, by pressing a corresponding number key a predetermined number of times, but inputting two consecutive vowels. In order to make the number keys have to be pressed three to five times, there is a problem in that the keys have a coarse shape by assigning a plurality of vowel combinations to one key.

Another conventional technology related to an English letter input method and apparatus is disclosed in Korean Patent Laid-Open Publication No. 1996-0307897.

3 is a plan view illustrating a key input device disclosed in Japanese Laid-Open Patent Publication No. 1996-0307897.

The alphabet input device illustrated in FIG. 3 is configured to be suitable for writing instruments such as warp, personal computer, and the like, and divides the consonant area and the vowel area, and divides them into upper, middle, and lower parts, and arranges the English alphabet so that the five fingers of the right hand are separated. It is proposed to input key using all. In other words, a character with a high frequency of occurrence is placed at a finger position where it is easy to press, and a key having a low frequency of use is placed at a key corresponding to a finger having a low activity such as a little finger.

In the key input device shown in FIG. 3, the keys are arranged to be input using five fingers, thereby bringing efficiency and speed of character input. However, there is a limit in applying them to communication terminals. The English alphabet was not inconvenient to enter while holding down the shift key. In addition, there is a problem that the user takes a considerable time to learn the arrangement of the keys because there is a lot of differences from the English letters arranged on the five fingers of the keyboard.

As another related art related to an English letter input method and apparatus, there is one disclosed in Korean Laid-Open Patent Publication No. 2001-0098105. This is a conventional T9 layout method, but the input method is improved only, the first of the three alphabets arranged on one numeric key is input by pressing the corresponding numeric key, the second alphabet is the corresponding numeric key Enter by pressing * key, and the third alphabet is entered by pressing the # key after pressing the number key. However, this method was inconvenient to use two keys to input one alphabet.

The present invention aims to input characters conveniently and quickly by increasing the number of keys for inputting characters and arranging them appropriately.

Another object of the present invention is to enable excellent performance in inputting characters using both hands.

Another object of the present invention is to input alphabet letters conveniently and quickly by distinguishing and arranging high and low occurrence frequencies of alphabet letters.

It is still another object of the present invention to assign a vowel alphabet and similar phonetic Korean vowels to the same key so that the user can easily remember the English alphabet arrangement.
