Scientific developments have enabled the application of virtual reality (VR) technology in various fields. However, this technology is disadvantaged by low recognition, existence of bias, lack of precision, and fatigue of text input in VR environments. To address these problems, this study proposed a spatial enhancement technique. This study investigated the effectiveness of spatial enhancement keys of a virtual keyboard from various angles and explored the impact of enhanced response time and enhanced protrusion distance on the spatial enhancement technology. Finally, the following conclusions are obtained: (1) The average text input performance of the keyboard using the spatial enhancement technique is significantly better than that of the ordinary virtual keyboard without using the spatial enhancement technique. (2) The recommended time interval for enhanced response time and the protrusion distance are 0-100 ms and 1.85 diopter, respectively. The keyboard angle insignificantly affects the input through the keyboard performance.
科学的发展使虚拟现实（VR）技术能够应用于各个领域。然而，该技术在 VR 环境中存在识别率低、存在偏差、精度不足和文本输入疲劳等问题。针对这些问题，本研究提出了一种空间增强技术。本研究从多个角度研究了虚拟键盘的空间增强键的有效性，并探讨了增强响应时间和增强突出距离对空间增强技术的影响。最后得出以下结论：（1）使用空间增强技术的键盘的平均文本输入性能明显优于未使用空间增强技术的普通虚拟键盘。（2）推荐的增强响应时间和突出距离的时间间隔分别为 0-100ms 和 1.85 屈光度。键盘角度对通过键盘输入的性能没有显著影响。
