本文介绍了一种基于触摸屏的压力键盘的设计和评估，以调查压力作为移动的设备输入的新方法的可能性。轻按触摸屏会生成一个小写字母，重按会生成一个大写字母。其目的是为了提高输入时的性能混合情况下的文本，或转移字符经常用于表情符号等实验比较了两种不同形式的压力输入（驻留和快速释放）对标准的换档键键盘，与用户都坐着和走路。结果表明，快速释放是最快的输入混合的情况下，文本与停留是最准确的，即使当用户是移动的。结果表明，压力输入可以优于移动的文本输入的标准Shift键键盘设计。
This paper describes the design and evaluation of a touch screen-based pressure keyboard to investigate the possibilities of pressure as a new method of input for mobile devices. A soft press on the touchscreen generated a lowercase letter, a hard press an uppercase one. The aim was to improve input performance when entering mixed-case text, or shifted characters often used for emoticons, etc. An experiment compared two different forms of pressure input (Dwell and Quick Release) against a standard shift key keyboard, with users both sitting and walking. Results showed that Quick Release was the fastest for input of mixed case text with Dwell being the most accurate, even when users were mobile. The results demonstrate that pressure input can outperform a standard shift-key keyboard design for mobile text entry.
