Purpose : This study aims to identify the correlation between binocular visual function and Cybersickness induced by vection in HMD VR content.
Methods : The subjects were 52 adults aged 20 to 40 with no issues in near visual acuity.
Binocular visual function and phoria, near point accommodation, near point convergence, binocular accommodation facility, stereo acuity, relative accommodation teat was assessed before the use of VR contents, and the subjects used three different VR contents categorized by optic flow. Cybersickness was measured with a virtual reality sickness questionnaire (VRSQ).
A Pearson’s correlation coefficient was calculated to identify the linear relationship between the binocular visual function and the cybersickness using an alpha level of 0.50.
Results : Content T and R showed a significant increase in cybersickness (p<0.001) for all items after using VR content. There was no significant difference in oculomotor discomfort for content B. Correlation analysis showed that near phoria was significantly correlated with disorientation (p<0.050) and total VRSQ (p<0.050) in Content T, and oculomotor discomfort (p<0.050) in Content R. The correlation analysis showed that oculomotor discomfort was significantly correlated with disorientation (p<0.050). The binocular accommodative facility was significantly correlated with the overall VRSQ of content T (p<0.050) No other binocular visual functions demonstrated a significant correlation with cybersickness components.
Conclusion : As a result of cyber motion sickness, it is thought that the optical flow element of the content implementing 3D has a higher effect than the user's personal characteristics or the effect of the binocular function itself on cyber motion sickness. In future studies, it is thought that there is a need to consider the visual element and visual perception element of VR content.
