Applying Engineering Anthropometry to Mitigate Eye Strain in Virtual Environments
DescriptionEye strain is a common occupational health issue and barrier for users of stereoscopic displays such as virtual reality (VR) headsets. Despite its prevalence, clear ergonomic guidelines for designing virtual environments can be difficult to find -- particularly the optimal depths at which to place user interfaces and key visual elements to mitigate eyestrain. This paper addresses this gap by providing concrete recommendations aimed at reducing eyestrain from the vergence-accommodation conflict and binocular divergence. Using Monte Carlo simulations, comfortable viewing ranges and far clipping distances that accommodate 99% of users were calculated based on interpupillary-distance measurements from the ANSUR I, ANSUR II, and CAESAR databases. Tables and figures are provided to enable designers and researchers to directly look up these limits, given the focal plane distance of their specific display (e.g., a VR/AR headset) and IPD calibration method -- either a fixed IPD setting or individual calibration with anticipated measurement errors. Examples demonstrate how to apply these findings in real-world scenarios.
