Abstract

The present study analysed the anthropometric characteristics of an integrated head-ear dataset to advance the ergonomic design of head-wearable products. By integrating 3D scanning, casting techniques, and template registration methods, scan data from 200 Korean participants were processed and 88 head and ear dimensions were measured. Among the head and ear dimensions, 95.5% showed larger average sizes in males than in females (mean difference = 0.3-25.1 mm; mean ratio = 1.02-1.37), with males exhibiting 67.0% greater variability (SD ratio = 1.01-1.36). Significant age-related changes were observed in 30.7% of the dimensions, with the majority of significant increases occurring in ear height-related dimensions, which rose by 5.0-18.0% from individuals in their 20s to their 50s, such as ear length (mean ratio: 30s = 1.03, 40s = 1.04, 50s = 1.09). These results can be of use for designing head-wearable products.

头戴式产品使用3D扫描分析头部和耳朵的人体测量数据。

本研究分析了一个集成头耳数据集的人体测量特征，以推进头戴式产品的人体工程学设计。通过综合3D扫描、铸造技术、模板注册方法，对200名韩国参与者的扫描数据进行了处理，并测量了88个头部和耳朵尺寸。在头和耳尺寸中，95.5%的雄性比雌性大（平均差异为0.3 ~ 25.1 mm，平均比值为1.02 ~ 1.37），雄性比雌性大67.0% （SD比值为1.01 ~ 1.36）。30.7%的维度发生了显著的年龄相关变化，其中耳朵高度相关维度的显著增加最为显著，从20多岁到50多岁，耳朵长度等维度的显著增加幅度为5.0% ~ 18.0%（平均比值为：30多岁= 1.03,40多岁= 1.04,50多岁= 1.09）。这些结果可用于头戴式产品的设计。

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.
