How to evaluate the wearability of electronic air filtration masks

Abstract

Electronic masks are wearable devices that can replace common disposable masks. Understanding user discomfort is important for proper electronic mask evaluation and design, but the method has not been standardized yet. This study presents evaluation methods that can qualitatively and quantitatively assess user discomfort caused by wearing an electronic mask. User interviews, surveys, and laboratory experiments were conducted. The pulling force of the ear bands and the contact pressure distribution of the face were selected as quantitative evaluation variables. The task was determined in consideration of various mask use environments through user observation. The final evaluation method was applied to the comparative evaluation of the two masks. It is the first attempt to evaluate the usability of the electronic mask, and this evaluation method could improve user convenience by using it for product development and improvement.
