Data communication such as E‐mail has been mainly used via PC, but the Short Message Service (SMS) is widely used in mobile phone after the Personal Communication Service (PCS) was started. Broadcasting technology such DMB is also possible in mobile terminal. Recently, the E‐mail and searching internet is possible in broadcasting terminal such as remote controller of IP‐TV. The conversionce of terminals and services will be accelerated, if technology is updated. Today, numeric keypad is used in various fields, for example, telephone, mobile phone, remote controller, ATM machine, etc. Standardization of Korean keypad on which Korean alphabet characters are marked has been argued. In this paper, the current standard Korean keypad and current text input method of Korean from keypad will be reviewed, and the properties of proper standard Korean keypad is presented. Even though how to induce standardization of Korean keypad is very sensitive matter, it is also mentioned briefly.

Hangeul can be used in writing various languages around the world. For such reason, many regions of the world are considering the use of Hangeul, following the trend of the ‘Korean Wave.’ Accordingly, many researchers are studying methods to use Hangeul to write various languages and spread Hangeul around the world. Considering how to globalize the use of Hangeul and turn it into an international language, this paper suggests a three‐set type Hangeul keyboard for international use. In today’s mobile environment with smart‐phone devices, Hangeul is an excellent bridge that can connect various languages, as well as an optimal character which people lacking their own alphabet can easily use. The one‐hand keyboard suggested in this paper aims to be not only more scientific, but also more convenient for the users compared to previous inputting methods. It is also purposed to input various languages without much difficulties. In short, the goal of this paper is to present a one‐hand Hangeul keyboard that can be used to conveniently input various languages around the world. This paper leaves the study regarding the methods of writing the consonants/vowels of Hangeul to related experts, and focuses on finding an effective way of inputting character through a one‐hand Hangeul keyboard using previous consonants/vowels. In addition, regarding the standardization of a one‐hand inputting method which is still under discussion, this paper tries to suggest an alternative which considers the true meaning of a proper standardization.
