Abstract

In recent years, Virtual Reality (VR) and 3D User Interfaces (3DUI) have seen a drastic increase in popularity, especially in terms of consumer-ready hardware and software. While the technology for input as well as output devices is market ready, only a few solutions for text input exist, and empirical knowledge about performance and user preferences is lacking. In this paper, we study text entry in VR by selecting characters on a virtual keyboard. We discuss the design space for assessing selection-based text entry in VR. Then, we implement six methods that span different parts of the design space and evaluate their performance and user preferences. Our results show that pointing using tracked hand-held controllers outperforms all other methods. Other methods such as head pointing can be viable alternatives depending on available resources. We summarize our findings by formulating guidelines for choosing optimal virtual keyboard text entry methods in VR.
虚拟现实中基于选择的文本输入
近年来,虚拟现实(VR)和3D用户界面(3DUI)的受欢迎程度急剧上升,尤其是在面向消费者的硬件和软件方面。虽然用于输入和输出设备的技术已经为市场做好了准备,但只有少数文本输入解决方案存在,而且缺乏关于性能和用户偏好的经验知识。在本文中,我们通过在虚拟键盘上选择字符来研究VR中的文本输入。我们讨论了评估VR中基于选择的文本输入的设计空间。然后,我们实现了跨越设计空间不同部分的六种方法,并评估了它们的性能和用户偏好。我们的结果表明,使用跟踪手持控制器的指向优于所有其他方法。根据可用资源,其他方法(如头部指向)也是可行的替代方案。我们总结了我们的发现,并制定了在VR中选择最佳虚拟键盘文本输入方法的指导方针。
