불편도 평가를 통한 마스크 타입 웨어러블 기기의 인간공학적 설계 = Ergonomic Evaluation of Discomfort for the Development of a Mask-type Wearable Device

다국어 초록 (Multilingual Abstract)

Objective: This study investigated a perceived discomfort which can occur by the weight and loop type of a face mask type wearable device under simulated conditions.
Background: Despite of a rapidly growing interest in face mask type wearable devices, most studies on a face mask have focused on a lightweight disposable mask while few studies have been conducted to evaluate an effect of their weight on a perceived discomfort.
Method: The total of fifteen participants evaluated eight different face masks with four levels of weight and two types of loop. For each session, they were either seated or walking at a speed of 4km/h for thirty minutes while wearing a face mask with a certain weight. Then, they rated a level of discomfort on face, ear, and neck as well as overall discomfort every ten minutes.
Results: The level of overall discomfort was significantly affected by all the experimental factors such as weight and loop type of a mask as well as activity and hours of use.
Also, levels of discomfort on face, ear, and neck could significantly predict an overall discomfort with an adjusted R2 value of 0.917. It was also found that discomfort on face was the factor which had the strongest influence on an overall discomfort.
Overall, the participants felt comfortable wearing a face mask with weight of up to 100g during 30 minutes of walking at a speed of 4km/h.
Conclusion: Although weight of 150g for a face mask-type wearable device can be acceptable for certain people, its weight is recommended to be less than 100g with a head loop to be comfortably used in a daily life such as working in an office or walking outside.
Application: The result of this study can be applied to determine an appropriate weight and loop type of a face mask type wearable device.
