Investigating the effect of wearing masks on office work in indoor environments during a pandemic using physiological sensing

ABSTRACT

The spread of pandemics has adverse effects on the lives of people in various ways. For people who need to work in the office and other indoor environments, wearing a mask has become an essential precaution to reduce the spread of the virus and thereby the risk of disease transmission. Therefore, it is important to understand how wearing a mask will affect people while they are performing daily office work. This paper aims to investigate the effect of wearing a mask on the physiological responses and task performance of those who work in office environments during the pandemic period. The two most commonly used masks (i.e., cloth and surgical masks) are chosen for evaluation. The work engagement, mental workload, skin conductance level (SCL), heart rate (HR), as well as the overall performance of 20 subjects while they are completing simulated office tasks are collected and analyzed. Although the results vary across different individuals, they reveal that wearing a mask during a pandemic period will potentially reduce the mental workload and SCL of people for specific types of tasks. In addition, the task performance (correct number and correct rate) of the subjects is worse when wearing a mask, which is highly correlated to the results of the mental workload and SCL. However, there is no one-size-fits-all pattern to conclude the effect of wearing masks on work engagement and HR. This study provides a valuable reference for those who need to wear a mask while working. © 2022 Elsevier Ltd
