Abstract

Visually induced motion sickness (VIMS) is a common discomfort response associated with vection-provoking stimuli. It is suggested that VIMS susceptibility depends on the ability to regulate visual performance during vection. To test this, in total 29 participants, with VIMS susceptibility assessed by Motion Sickness Susceptibility Questionnaire, were recruited in three successive experiments to perform sustained attention to response tests (SARTs) while watching dot pattern stimuli known to provoke roll-vection. In general, SARTs performance was impaired in the central visual field (CVF), while improved in peripheral visual field (PVF), suggesting the reallocation of attention during vection. Moreover, VIMS susceptibility was negatively correlated with the effect sizes, suggesting that participants who were less susceptible to VIMS showed better performance in attention re-allocation. Finally, when trained to re-allocation attention from CVF to PVF, participants experienced more stable vection.

FINDINGS provide a better understanding of VIMS and shed light on possible preventive measures. Practitioner Summary: Allocating less visual attention to central visual field during visual motion stimulation is associated with stronger vection and higher resistance to motion sickness. Virtual reality application designers may utilize the location of visual tasks to strengthen and stabilize vection, while reducing the potential of visually induced motion sickness.
