In this paper, we present a QAZ keyboard, which is a QWERTY keyboard that facilitates one-handed thumb input for a mobile device with a large touchscreen. To design the keyboard, we first conducted experiments to investigate pointing performance on a large mobile touchscreen using one-handed thumb. The results showed that vertically long areas around the center of the touchscreen would be suitable to place a keyboard in terms of accuracy and time of pointing. Based on this finding, we designed and implemented the QAZ keyboard for Android-based devices. A longitudinal study with 4 participants showed that the mean text entry speed was 18.2wpm, and the mean error rate was 9.1%. Moreover, a comparative study of the QAZ keyboard compared to a QWERTY keyboard showed that the QAZ keyboard’s error rate was significantly lower than the QWERTY keyboard.
