基于触摸面积的手部姿势对触摸屏文本输入行为的影响

Hand Posture's Effect on Touch Screen Text Input Behaviors: A Touch Area Based Study

Christopher Thomas, Brandon Jennings

摘要:

具有触摸键盘的移动设备已经变得无处不在,但是在这些设备上的文本输入仍然缓慢且容易出错。理解文本输入过程中的触摸模式对于为软键盘设计鲁棒的纠错算法可能很有用。在本文中,我们提出了一个软QWERTY键盘上的文本输入行为的分析在三个不同的文本输入姿势:食指,一个拇指,和两个拇指。我们的工作扩展了[1]的工作,考虑了手指与智能手机键盘接触的整个表面积,而不是将每个触摸解释为单个点。为此,我们在一项有8名参与者的实验室研究中捕获了每个按键的触摸区域,并计算了偏移量、出错率和尺寸测量值。然后,我们重复了[1]中描述的原始实验,并表明当基于触摸面积的偏移计算与两种姿势的触摸点相比时存在显着差异。

英文摘要:

Mobile devices with touch keyboards have become ubiquitous, but text entry on these devices remains slow and errorprone. Understanding touch patterns during text entry could be useful in designing robust error-correction algorithms for soft keyboards. In this paper, we present an analysis of text input behaviors on a soft QWERTY keyboard in three different text entry postures: index finger only, one thumb, and two thumb. Our work expands on the work of [1] by considering the entire surface area of digit contact with the smartphone keyboard, rather than interpreting each touch as a single point. To do this, we captured touch areas for every key in a lab study with 8 participants and calculated offsets, error rates, and size measurements. We then repeated the original experiment described in [1] and showed that significant differences exist when basing offset calculations on touch area compared to touch points for two postures.
