Mobile keypad having a shortcut key and method for inputting english alphabet using the same}

The present invention relates to a method of inputting an English letter using a mobile phone keypad, and more particularly, to change an arrangement of input keys of a mobile phone keypad, and to further add shortcut keys of 'My word', 'Change,' Verb ', and upper and lower sensor bars. The present invention relates to an alphabetic character input method using a mobile phone keypad equipped with a shortcut key configured to more easily and quickly input an alphabetic character, add a word autocompletion function, and facilitate conversion of a verbal alphabetic character.

In general, as a mobile phone is established as a means of daily information transmission and communication, it enables not only a voice call but also a video call, and provides a variety of mobile-based service environments ranging from data communication based on wireless Internet. have. In addition, there is a trend to have a variety of functions using the character, such as the electronic notebook function, PDA function, including a wireless text transmission and reception function of the mobile phone.

However, inputting characters using a keypad of a very small mobile phone compared to a computer keyboard has a problem that is very troublesome and takes a lot of time.

In particular, when looking at the domestic and foreign mobile phones being developed, the Korean alphabet input method has been developed a convenient keypad arrangement and its usage methods, such as Cheonjiin method and Naragle method, but for general English character input does not deviate from the conventional keypad arrangement Also, even in the text input method, an efficient method cannot be found.

In order to input a conventional English letter, there is a method of inputting an alphabet by using a numeric key and a T9word method combining a number of commonly used words. Among these methods, the T9word method automatically expresses the most frequently used words among words starting with a specific alphabet, but when used, they tend to deviate from the words that users want to use.

In addition, there is a method of inputting the alphabet of all the keypads in the form of a computer keyboard and inputting all alphabets through a familiar computer keyboard format. However, this can save the letter input time, but the number of each key is too large. The disadvantage is that the size increases.

Figure 1 (a) (b) is a view showing a conventional mobile phone 100 and the keypad unit provided in the mobile phone 100, in general, the keypad 150 of the conventional mobile phone is a menu, confirm, send, cancel, power key It has an upper keypad 130 and a lower keypad portion 140 is assigned to the alphabet or Hangul characters of the English alphabet with the numbers from 0 to 9 and '#' and '*' as a function key.

In addition, the characters input through the keys of the upper and lower keypads 130 and 140 are displayed on the mobile phone display window 120.

The alphabet for inputting the English letters is assigned to the lower keypad 140 configured as described above with each number. In general, the English alphabet input uses three alphabets on each of the keypad keys of the mobile phone, and inputs all the words accordingly. Let's do it.

For example, as illustrated in FIG. 1A, the lower keypad 140 of the cellular phone is a keyboard having an input key 4 × 3 matrix, and numbers and two to three alphabets are written on each input key. That is, the first column of the first row is the numbers '1' and 'QZ', the second column is '2' and 'ABC', the third column is '3' and 'DEF', and the second row, first column is '4' and 'GHI', Column 2 is '5' and 'JKL', Column 3 is '6' and 'MNO', Row 3, Column 1 is '7' and 'PRS', Column 2 is '8' and 'TUV' In the fourth row, the first column has '*', the second column has '9' and 'WXY', and the third column has '#'.

As another example, as shown in (b) of FIG. 1, as a keyboard of an input key 4 × 3 matrix, the number '1' key is used for '@: /', the number '2' button is used for the 'ABC' and the number '3' button. Like 'DEF', '4' button, 'GHI', etc., the alphabet is assigned to each button three or four sequentially from A to Z.

As described above, in the lower keypad 140 of the cellular phone in which input keys are arranged as shown in FIG. 1 (a) and (b), the alphabetic characters assigned to the respective input keys correspond to the alphabetic characters according to the number of times the buttons are pressed in sequence. Data is input and displayed on the mobile phone display window 120. In other words, after the user sets up the English letter input, if the user presses the number '2' key once, 'A' is pressed again, 'B' is pressed again, and if it is pressed again, the data corresponding to 'C' is generated. . Press again or continue pressing to enter the number '2'.

Therefore, in order to generate the data corresponding to 'B', the user must press the number '2' key twice. In order to generate the data corresponding to 'C', the user must press the number '2' key three times. do.

As such, the corresponding alphabets are sequentially displayed on the display window 120 of the mobile phone according to the input key pressed by the user.

However, the English character input by such an input key arrangement has a problem in that the input efficiency is lowered because it is necessary to press from one stroke to three strokes in order to input a desired alphabet to each key. In addition, when the alphabets assigned to the same letter or the same input key are continuously inputted, a problem arises in that, after inputting the first alphabet, the cursor on the display window must be moved or wait for a certain time until the cursor is automatically moved.

In addition, in order to complete a sentence using an English letter, a problem arises in that an input key to which an alphabet corresponding to a sentence is assigned is pressed one by one.

In other words, if three to four alphabets are assigned to one input key, such as an input key on a mobile phone keypad as in the prior art, it is necessary to press one input key several times in order to input the third and fourth alphabets. As a result, a problem arises that the input speed of the alphabetic characters is significantly reduced.

The present invention has been made to solve the above-described problems, the word autocomplete function is formed when three or more alphabets are input according to the English alphabet input, and a shortcut key is configured to easily input the most commonly used verb type when entering the English alphabet. An object of the present invention is to provide a mobile phone keypad and an English character input method using the same.
