Automatic generation of GUI for smartphone IME by classifying user behavior patterns

Various user's situation and small screen compared with computer keyboard influence the performance of the IME (Input Method Editor, a program that allows users to enter characters and symbols). According to the hand that a user is using, it has a significant effect on the IME input. In this paper, we propose a method based on decision tree to generate GUI automatically for the IME. We collect sensor data from Android smartphone and key data that user enters with IME. A comparison experiment with different input postures was conducted to show the feasibility of the proposed method.
