  • Keypad used in the portable terminal based on the touch screen such as current smart phones is complex on the input method because of placement for use a small screen on a character or number button and is inconvenient. In this paper, we propose a combination method for the Hangul through touch and drag. First, only keypad for consonants is displayed, if a single consonant is selected by touch, then the keypad for vowels will be displayed around the consonant. Dragging in the keypad is combined into a vowel by depending on the drag path. This method can input Hangul by rapid and intuitive process compared to conventional methods. Simulation results show that the proposed method is very efficient in terms of speed and convenience compared to the conventional methods.
