Abstract :Smartphones insert ignore into journalissuearticles values(SP); terminals are becoming the most popular media for virtual reality insert ignore into journalissuearticles values(VR); and augmented reality insert ignore into journalissuearticles values(AR); effects with their central processing unit insert ignore into journalissuearticles values(CPU); and video capabilities. Simple VR headsets with reasonable costs can host smartphones, and they can together be used for many different applications. But with the outbreak of Covid-19 pandemic, their usage has become essential for many people working from their homes. VR and AR capabilities provide a much richer experience for entertainment, gaming, and video conferencing. The increasing popularity of 3D virtual worlds add up to this usage. On the technology side, multi-radio connectivity is supported both on terminal and network side. A certain risk may arise when using SP VR headsets for such applications requiring a broadband Internet connectivity. SPs with multi-radio connectivity feature may elevate specific absorption rate insert ignore into journalissuearticles values(SAR); values in those cases. The smartphone used for VR and AR applications is positioned in front of the eyes; and there is very limited ventilation in VR/AR headsets. Authors’ model aims simulate these exposure scenarios in 4G and 5G mobile telecommunication frequencies by finite element method insert ignore into journalissuearticles values(FEM);; and, possible thermal and non-thermal risks of related electromagnetic insert ignore into journalissuearticles values(EM); radiation on human eye according to the outputs of the model are discussed.
