摘要

为了研究虚拟现实中老年人对汉字字体大小、文字背景不透明度和字体笔画的可识别性,我们招募了老年和青年参与者进行了 VR 实验,并使用眼动跟踪技术记录了任务完成时间和错误率数据。经过分析,我们得出结论:老年人的最小识别字体大小为 30 dmm,最佳字体大小为 60 dmm,年轻人的最小识别字体大小为 20 dmm,最佳字体大小为 40 dmm。字体样式对老年人有显著影响(p = 0.000*)。此外,对于小于 20 dmm 和大于 50 dmm 的字体大小,带有笔画和 50% 以上半透明背景的文字可以提高老年人的可读性。在字体大小合适的情况下,字体风格对老年人的影响不大。这些结论可以为面向老年人的 VR 中文字体设计提供参考。

Effects of font size, stroke, and background on the legibility of Chinese characters in virtual reality for the elderly.

To investigate the legibility of Chinese characters' font size, text background opacity, and font stroke for the elderly in virtual reality, we recruited old and young participants to conduct experiments with VR and used eye-tracking technology to record the data of task completion time and error rate. After analysis, we concluded that the minimum recognition font size for the elderly is 30 dmm, and the best font size is 60 dmm, which is 20 and 40 dmm for young people. The font style has a significant effect on old people (p = 0.000*). Besides, for font sizes smaller than 20 dmm and bigger than 50 dmm, text with strokes and over 50% semi-transparent backgrounds can improve legibility for the elderly. With a suitable font size, the influence of font style on the elderly is not significant. These conclusions can provide a reference for the elderly-oriented Chinese font design in VR.

期刊介绍: Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
