Abstract

Using soft keyboard is the main text entry method on mobile devices. However, texting on small mobile devices, such as smartphones remains challenging and inconvenient. It’s because of the small size of keys, the difference between view angle and touch point, the tilt of the device etc. When entering text, the human eye conducted visual search for the target key, then casted their attention on the symbol on the button. In this research we would like to understand how the touch points would be affected by the symbol positions on the button. A click-based App has been designed to observe, record, and analyze the data and behaviors of the subjects when they clicked on the keypad buttons. In the experiments the subjects have been asked to perform a series of clicking on the target points under five conditions that the symbols appeared at the center of the buttons, the upper right portions, the lower right portions, the upper left portions and the lower left portions. According to analyses we fund that under the circumstances of different symbol positions, the subjects tended to click on the positions where the symbols appeared instead of the centers of the buttons.
