The Use of Smart Glasses in the Assembly Industry Can Lead to an Increase in the Local Maximum Values of the Forehead Temperature

Abstract

Smart glasses are an emerging technology designed to assist workers in a variety of industrial workplaces. In many cases, their continued development has led to a better working performance. Thus, the radiation of heat is becoming an issue that will even exacerbate, because future smart glasses require faster CPU and a larger memory. Consequently, thermal management of smart glasses is essential for user safety and comfort. In this study, the temporal evolution of the temperature on the user’s forehead was investigated during the assembly work. Two different smart glasses and a tablet were used to provide twelve participants with visual instructions. The forehead temperature was measured before and after the assembly task using a thermal camera system. The analysis revealed statistically significant differences between the two smart glasses and the tablet. The results indicate that certain types of smart glasses can lead to a temperature rise during assembly work.
