Description

{Method for Mapping Alphabet and Hangul using Six Key}

The present invention relates to a method of matching alphabetic and Korean characters, and more particularly, to a method of mapping alphabets and Korean alphabets using a keypad of a new keypad type of six buttons.

2. Description of the Related Art In recent years, various portable terminals including a mobile phone have been released due to the development of information communication, for example, a mobile phone using a wireless communication network. It is rapidly spreading. In addition, since wireless Internet service is provided through a portable terminal, information is shared through a portable terminal for text messages, e-mail, and the like.

Here, the portable terminal has no problem in receiving data due to the limitation of maintaining its slim appearance due to its characteristics, but it has a problem that it is considerably difficult to transmit desired sufficient character information to the other party. In other words, since the portable terminal is configured to be small enough to be held by hand, the character input unit provided in such a portable terminal also has a basic form in which the size and quantity of the keypad can input the minimum contents (number, Alphabet, etc.), it is possible to input very simple sentences and characters, so that the range of information contents to be transmitted is not only narrow, but also it is difficult to use such a method in which a keyboard is repeatedly pressed in the input method. And the like.

This problem also occurs in a portable terminal having an expandable keypad portion coupled with a Bluetooth and a hinge manner to the terminal body as well as the portable terminal. When the keypad portion is coupled to the terminal body, the size of the keypad portion, that is, The volume of the terminal itself becomes large so that it is inconvenient to carry.

Accordingly, existing portable terminals are limited in terms of searching for information requested by users and sharing and providing information. In order to positively utilize wireless Internet service using portable terminals, a portable keyboard capable of promptly and promptly inputting messages This is an inevitable procedure.
