移动文本输入方法通常通过让研究参与者复制短语来评估。然而，目前还没有由移动用户编写的可用短语集。相反，研究人员转而使用可能外部效度较低的发明短语。此外，没有可用的短语集，其短语已被验证为易于记忆。在本文中，我们展示了实际用户在实际移动设备上编写的移动电子邮件句子的集合。我们从安然员工在黑莓移动设备上撰写的电子邮件中获取了我们的句子。我们提供了有关句子的记忆难易程度以及用户在全尺寸键盘上输入这些句子的速度和准确度的经验数据。使用这些经验数据，我们构建了一系列建议用于文本输入评估的短语集。
Mobile text entry methods are typically evaluated by having study participants copy phrases. However, currently there is no available phrase set that has been composed by mobile users. Instead researchers have resorted to using invented phrases that probably suffer from low external validity. Further, there is no available phrase set whose phrases have been verified to be memorable. In this paper we present a collection of mobile email sentences written by actual users on actual mobile devices. We obtained our sentences from emails written by Enron employees on their BlackBerry mobile devices. We provide empirical data on how easy the sentences were to remember and how quickly and accurately users could type these sentences on a full-sized keyboard. Using this empirical data, we construct a series of phrase sets we suggest for use in text entry evaluations.
