Abstract
Font size is highly related to the legibility and visual fatigue in OST-HMDs, but the effects of font size on these factors remain further explored. An experiment was conducted to investigate the effects of a wider range of Chinese character font size (0.32°-1°) on legibility and visual fatigue, as well as to determine the optimal font size. Results showed that 0.32° had the worst legibility, but there was no continuous improvement as font size increased. A larger font size was found to be beneficial in reducing visual fatigue until it reached 0.95°, beyond which visual fatigue would relatively increase. Font size smaller than 0.32° should be rejected while a larger font size does not always provide more benefits. Considering legibility, visual fatigue and efficiency of text presentation, 0.84° is a relatively optimal Chinese character font size.
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.
