Size of Chinese Head and Face Related to Respiratory Protective Device Design
International Conference on Applied Human Factors and Ergonomics, 2021This study presents a two-dimensional distribution table of Chinese head and face dimensions related to the design of respiratory protective devices. The two-dimensional distribution table is set up according to the coverage rate of head width shape length of adult men (18–60 years old) and adult women (18–60 years old).

Compliance Prediction of a Novel Head Protection Device for Elderly Patients With Fall Risk
The American Surgeon™, 2023Brain injury from ground level falls (GLF) is common and has substantial morbidity. We identified a potential head protection device (HPD). This report describes predicted future compliance. 21 elderly patients were provided a HPD and were evaluated on admission and after discharge. Compliance, ease of use, and comfort were evaluated.
