A character inputting system using one 5-way key module has been developed for use in mobile devices such as cell phones, MP3 players, navigation systems, and remote controllers. All Korean and English alphabet characters are assembled by two key clicks, and because the five keys are adjacent to each other and the user does not have to monitor his/her finger movements while typing, the speed of generating characters can be extremely high and its convenience is also remarkable.
