Smartphones are becoming more advanced and the use of touch input is increasing. Therefore, various keyboards can be implemented in smartphones. Unlike a button input method, a 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, a user keyboard input method based on Android is proposed and implemented. Compared with conventional methods, the proposed method results in a rapid improvement in typing speed.
