论文摘要
基于手动的互动，例如使用手持式控制器或制作手势，已被广泛用作与虚拟现实（VR）和增强现实（AR）头部安装的显示器（HMDS）进行交互的主要方法。相比之下，免提互动避免了对用户的手的需求，尽管它可以带来其他好处，但在探索和评估这些HMD的无提技巧方面的研究有限。随着VR HMD无处不在，人们将需要进行文本编辑，这需要选择文本段。与免提互动类似，文本选择不充分。这项研究重点是通过免提互动进行文本选择。我们的探索涉及24名参与者的用户研究，以研究三种免提选择机制（居住，眨眼，语音）的性能，用户体验和工作量，以补充基于头部的指向。结果表明，眨眼在完成时间内超越了居中和声音。用户的主观反馈还表明，眨眼是用于文本选择的首选技术。这项工作是第一个在VR HMD中探索用于文本选择的免费互动的工作。我们的结果为在这一重要领域进行进一步研究提供了一个坚实的平台。
Hand-based interaction, such as using a handheld controller or making hand gestures, has been widely adopted as the primary method for interacting with both virtual reality (VR) and augmented reality (AR) head-mounted displays (HMDs). In contrast, hands-free interaction avoids the need for users' hands and although it can afford additional benefits, there has been limited research in exploring and evaluating hands-free techniques for these HMDs. As VR HMDs become ubiquitous, people will need to do text editing, which requires selecting text segments. Similar to hands-free interaction, text selection is underexplored. This research focuses on both, text selection via hands-free interaction. Our exploration involves a user study with 24 participants to investigate the performance, user experience, and workload of three hands-free selection mechanisms (Dwell, Blink, Voice) to complement head-based pointing. Results indicate that Blink outperforms Dwell and Voice in completion time. Users' subjective feedback also shows that Blink is the preferred technique for text selection. This work is the first to explore hands-free interaction for text selection in VR HMDs. Our results provide a solid platform for further research in this important area.
