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.
