摘要

手机文本输入已经成为许多人日常生活中越来越重要的一部分。虽然大多数输入都是通过在虚拟QWERTY键盘上敲击单个字母来实现的，但情况并非如此。我们探讨了用户如何能够很好地学习一个模糊的键盘，这个键盘模仿标准的QWERTY布局，但不需要用户点击特定的键。我们的研究表明，对于视力较差或没有视力的用户来说，这种键盘是一种可行的文本输入技术，经过8小时的练习，用户达到了每分钟19.09个单词和2.08%的字符错误率。

Exploring an Ambiguous Technique for Eyes-Free Mobile Text Entry

Mobile text entry has become an increasingly important part of many peoples' daily lives. While most input occurs through individual letters being tapped on a virtual QWERTY keyboard, this does not have to be the case. We explore how well users are able to learn an ambiguous keyboard that is modeled after a standard QWERTY layout but does not require users to tap specific keys. We show that this keyboard is a plausible text entry technique for users with little or no vision, with users achieving 19.09 Words per Minute (WPM) and 2.08% Character Error Rate after 8 hours of practice.
