Does interpupillary distance (IPD) relate to immediate cybersickness?

Widespread adoption of virtual reality (VR) will likely be limited by the common occurrence of cybersickness. Cybersickness susceptibility varies across individuals, and previous research reported that interpupillary distance (IPD) may be a factor. However, that work emphasized cybersickness recovery rather than cybersickness immediately after exposure. The current study (N=178) examined if the mismatch between the user's IPD and the VR headset's IPD setting contributes to immediate cybersickness. Multiple linear regression indicated that gender and prior sickness due to screens were significant predictors of immediate cybersickness. However, no relationship between IPD mismatch and immediate cybersickness was observed.
