文本编辑非常重要，并且是最复杂任务（例如撰写电子邮件或浏览网页）的核心。台式机和触摸设备上存在高效且复杂的技术，但增强现实头戴式显示器 (AR-HMD) 的开发仍未充分。 AR显示中进行文本选择是文本编辑之前的必要步骤，通常使用手动跟踪、语音命令、眼睛/头部注视等技术，这些技术繁琐且缺乏精确度。在本文中，我们探索使用智能手机作为输入设备来支持 AR-HMD 中的文本选择，因为它的可用性、熟悉度和社会可接受性。我们提出了四种免眼文本选择技术，全部使用智能手机——连续触摸、离散触摸、空间移动和光线投射。我们在用户研究中对它们进行了比较，其中用户必须选择不同粒度级别的文本。我们的结果表明，我们使用智能手机作为触控板的连续触摸在任务完成时间、准确性和用户偏好方面优于其他三种技术。
Text editing is important and at the core of most complex tasks, like writing an email or browsing the web. Efficient and sophisticated techniques exist on desktops and touch devices, but are still underexplored for Augmented Reality Head Mounted Display (AR-HMD). Performing text selection, a necessary step before text editing, in AR display commonly uses techniques such as hand-tracking, voice commands, eye/head-gaze, which are cumbersome and lack precision. In this paper, we explore the use of a smartphone as an input device to support text selection in AR-HMD because of its availability, familiarity, and social acceptability. We propose four eyes-free text selection techniques, all using a smartphone — continuous touch, discrete touch, spatial movement, and raycasting. We compare them in a user study where users have to select text at various granularity levels. Our results suggest that continuous touch, in which we used the smartphone as a trackpad, outperforms the other three techniques in terms of task completion time, accuracy, and user preference.
