Abstract
Smartphones are becoming more advanced, and the use of touch input is increasing. Therefore, various keyboards can be implemented in smartphones. Unlike the button input method, the touch input method can have non-fixed keys that can be freely arranged. Many users are thus interested in the touch input method. In this paper, we propose a Korean grapheme model called ‘Auto Toggle’ by using auto switching between consonants and vowels of Hangul. Also, Auto Toggle is designed and implemented based on the Android platform. Finally, we describe the results of a performance evaluation for the number of buttons pushed for each single syllable of Hangul compared with conventional methods. Additionally, Auto Toggle results in a rapid improvement on typing speed with respect to sentence generation.
