具有触摸屏的移动的电话已经被引入市场。然而，对于移动的电话的触摸界面设计进行了很少的研究。本研究调查了触摸键的大小和位置对移动的手机交互中流行的单手拇指输入的影响。在实验中检查了三种不同的触摸键尺寸（即，具有4mm、7mm和10mm宽的正方形形状）和二十五个位置。结果提供了两组触摸键的位置（一个适当的和不适当的区域）方面的三个可用性措施，包括成功率，错误的数量，并按下方便。此外，一个基于命中分布的算法被应用到目标选择任务，这在统计上提高了性能。本研究结果可应用于触控按键设计，以提升具有触控屏幕的移动的手机的可用性。
Mobile phones with a touch screen replacing traditional keypads have been introduced to the market. Few studies, however, have been conducted on the touch interface design for a mobile phone. This study investigated the effects of touch key sizes and locations on the one-handed thumb input that is popular in mobile phone interactions. Three different touch key sizes (i.e. square shape with 4mm, 7mm, and 10mm wide) and twenty five locations were examined in an experiment. The results provided two groups of touch key locations (an appropriate and an inappropriate region) with respect to three usability measures including success rate, number of errors, and pressing convenience. In addition, a hits distributions based algorithm was applied to target selection tasks, which statistically improved the performance. The results of this study could be used to design touch keys so as to enhance the usability of mobile phones with a touch screen.
