在增强现实中复刻手机双指打字，让用户轻松输入文本。
STAR: Smartphone-analogous Typing in Augmented Reality
- 用虚拟键盘模拟手机双指输入，手指皮肤上显示键盘。
- 30分钟练习后达21.9词/分钟，错误率仅0.3%。
- 适合希望在AR中高效输入的用户，尤其熟悉手机打字者。
尽管文本输入是增强现实（AR）应用中的核心且频繁任务，但设计一种高效且易用的AR文本输入方法仍是未解难题。本文提出STAR，一种模拟智能手机双指打字的AR文本输入技术，利用用户对手机打字的熟悉感。使用STAR时，用户在手部皮肤上的虚拟QWERTY键盘上进行拇指打字。在一项评估研究中，参与者经过30分钟练习后，平均打字速度达21.9词/分钟（即其手机打字速度的56%），平均错误率为0.3%。我们进一步分析了STAR与手机打字间性能差距的主要因素，并探讨缩小该差距的可能途径。
原文摘要 · Abstract (English)
While text entry is an essential and frequent task in Augmented Reality (AR) applications, devising an efficient and easy-to-use text entry method for AR remains an open challenge. This research presents STAR, a smartphone-analogous AR text entry technique that leverages a user's familiarity with smartphone two-thumb typing. With STAR, a user performs thumb typing on a virtual QWERTY keyboard that is overlain on the skin of their hands. During an evaluation study of STAR, participants achieved a mean typing speed of 21.9 WPM (i.e., 56% of their smartphone typing speed), and a mean error rate of 0.3% after 30 minutes of practice. We further analyze the major factors implicated in the performance gap between STAR and smartphone typing, and discuss ways this gap could be narrowed.
