| 目的 目前基于移动设备背面屏输入技术的相关研究，大多集中于其在物理键盘布局或是体型较大的移动设备(如iPad)上的探究，而基于小型移动设备(如手机)的背面屏盲打输入法键盘布局的相关研究并不多见。手机背面虚拟键盘的使用可极大程度释放前屏空间，实现前屏交互任务与背屏文本输入的同步进行。基于此研究意义，探讨智能手机背面屏盲打输入法的可行性及设计方案。方法 通过用户访谈和文本输入测试，采集并分析24 167条用户输入数据。结果 智能手机背面屏的横向QWERTY键盘布局为左右拆分式，整体位于双手手持时偏上部的位置。结论 通过对用户在智能手机背面屏盲打输入偏好的研究，可以得出一个具有较强一致性的横向QWERTY键盘布局，为未来背面屏盲打输入法键盘布局设计提供指导。 |

| Existing studies on rear screen text input mostly focus on exploring physical keyboard layout on large mobile devices (e.g., iPad), ignoring the exploration of soft keyboard layout on the back of small mobile phones. The application of soft keyboard on the rear screen may greatly release the space of the front screen of a smartphone, ensuring that the user can perform primary interactive tasks on the front screen while conducting eyes-free text input on the rear screen. The purpose of this paper is to explore the feasibility of eyes-free text input on the back screen of a smartphone. Based on field observation of participants’ text input behaviors, 24, 167 user input data have been collected and analyzed. Participants preferred to divide the traditional QWERTY keyboard into left and right parts and placed them on the upper side of the rear screen of a smartphone for two-handed eyes-free text input. Based on the experimental results, we propose a general keyboard layout for eyes-free text input on the rear screen of a smartphone. We highlight the implication of this work for the design of all back-of-device-based applications. |
