Thermal Effect Estimation of Smartphone Virtual Reality Headsets on Human Eye by Finite Element Method

Abstract

Overview

Smartphones are increasingly used as media for virtual and augmented reality applications, especially accentuated during the Covid-19 pandemic for various applications like entertainment, gaming, and video conferencing.

Findings

• Virtual Reality (VR) and Augmented Reality (AR) applications are providing expanded experiences due to advancements in smartphone technology.
• Concerns arise with the usage of VR headsets as they feature multi-radio connectivity that may increase Specific Absorption Rate (SAR) values, which in turn could pose thermal and non-thermal risks to the eye due to electromagnetic radiation.
• Research was conducted using a finite element method to simulate exposure scenarios at 4G and 5G telecommunication frequencies and assess potential risks.

Conclusion

The study explores the implications of prolonged exposure to electromagnetic fields from smartphone VR headsets, underlining potential eye health risks. Continuous monitoring and further research into these findings are warranted due to the integration of high-frequency telecommunication bands in everyday devices.
