The increasing importance of virtual reality (VR) necessitates reading in VR environments. Nonetheless, there is a lack of research on the factors influencing reading performance (speed and accuracy) in VR. The purpose of this study is to investigate the influence of line length, number of lines, line spacing, and font size on the response time and accuracy of a Chinese comprehension task in VR. Thirty-two participants were required to read Chinese passages and answer 32 multiple-choice questions in VR. The results indicated that line spacing significantly affected reading speed. Meanwhile, the interaction between the number of lines and line spacing had a significant impact on reading accuracy. To improve reading speed and accuracy, it is advisable to use single-line spacing, 20 characters per line, and ensure that the vertical distance created by the number of lines and line spacing does not exceed the optimal field of view.

虚拟现实 (VR) 的重要性日益增加，需要在 VR 环境中阅读。尽管如此，目前还缺乏对影响VR阅读性能（速度和准确性）的因素的研究。本研究的目的是研究行长、行数、行距和字体大小对 VR 中汉语理解任务的响应时间和准确性的影响。32 名参与者需要在 VR 中阅读中文文章并回答 32 道选择题。结果表明，行间距显着影响阅读速度。同时，行数和行距之间的交互作用对读取精度有显着影响。为了提高阅读速度和准确性，建议使用单行间距，每行20个字符，
