The eye-shaped keyboard references the QWERTY key sequence, allowing the users to benefit from their experience using the QWERTY keyboard. The user interacts with an eye-shaped keyboard using rays controlled with both the hands. A character can be entered in one step by moving the rays from the inner eye regions to regions of the characters. A high-speed auto-complete system was designed for the eye-shaped keyboard. We conducted a pilot study to determine the optimal parameters, and a user study to compare our eye-shaped keyboard with the QWERTY and circular keyboards. For beginners, the eye-shaped keyboard performed significantly more efficiently and accurately with less task load and hand movement than the circular keyboard. Compared with the QWERTY keyboard, the eye-shaped keyboard is more accurate and significantly reduces hand translation while maintaining similar efficiency. Finally, to evaluate the potential of eye-shaped keyboards, we conducted another user study. In this study, the participants were asked to type continuously for three days using the proposed eye-shaped keyboard, with two sessions per day. In each session, participants were asked to type for 20min, and then their typing performance was tested. The eye-shaped keyboard was proven to be efficient and promising, with an average speed of 19.89 words per minute (WPM) and mean uncorrected error rate of 1.939%. The maximum speed reached 24.97 WPM after six sessions and continued to increase.展开更多
文字输入是虚拟现实(VR)环境中最常见的交互行为,目前主流的文字输入是通过激光瞄准的方式实现的,然而,现有方法存在诸多弊端,例如效率低、抖动大、扣动扳机容易误触发等,并不能满足VR环境下频繁输入词语的需求。因此,本文提出一种VR环...文字输入是虚拟现实(VR)环境中最常见的交互行为,目前主流的文字输入是通过激光瞄准的方式实现的,然而,现有方法存在诸多弊端,例如效率低、抖动大、扣动扳机容易误触发等,并不能满足VR环境下频繁输入词语的需求。因此,本文提出一种VR环境新型文字输入方式。首先,对键盘进行分区,使用手柄选择字符所在区域,辅以单词消歧算法,实现以单词为单位进行文本输入;其次,对使用者的点击坐标进行聚类分析,做一键多词处理;最后,设计出3种符合用户习惯的键盘布局,并确定出最优的布局。实验结果表明:利用该文本输入方式的最优布局速度高达13.44 WPM(Words per minute),准确率高达92.26%,相比于其他输入方式有较大提高。展开更多
