论文摘要
文本输入是虚拟现实（VR）系统中的常见活动。可用的免提技术数量有限，当用户的手忙碌（例如握住物品或基于手动的设备）时，用户可以执行文本条目。最常用的免提文本输入技术是Delltype，用户通过在特定时期内铺设字母来选择一封信。但是，由于每个字符选择的固定时间，其性能受到限制。在本文中，我们探索了VR中的另外两种免提文本输入机制：BlinkType和Nesucktype，它们利用用户的眼睛眨眼，颈部向前和向后移动以选择字母。通过用户研究，我们将两种技术的性能与Delltype进行比较。结果表明，用户可以使用BlinkType，Nesucktype和Delltype的平均文本输入率分别为13.47、11.18和11.65单词。用户的主观反馈将BlinkType显示为VR中文本输入的首选技术。
Text entry is a common activity in virtual reality (VR) systems. There is a limited number of available hands-free techniques, which allow users to carry out text entry when users' hands are busy such as holding items or hand-based devices are not available. The most used hands-free text entry technique is DwellType, where a user selects a letter by dwelling over it for a specific period. However, its performance is limited due to the fixed dwell time for each character selection. In this paper, we explore two other hands-free text entry mechanisms in VR: BlinkType and NeckType, which leverage users' eye blinks and neck's forward and backward movements to select letters. With a user study, we compare the performance of the two techniques with DwellType. Results show that users can achieve an average text entry rate of 13.47, 11.18 and 11.65 words per minute with BlinkType, NeckType, and DwellType, respectively. Users' subjective feedback shows BlinkType as the preferred technique for text entry in VR.
