眼球運動の適切制御による映像酔いの低減(<特集>VR心理学4)

'Sensory conflict' theory is one of well-known theories for motion sickness. We conducted two experiments to determine the effects of the conflict between actual (extra-retinal) eye-movement and visually-simulated (retinal) eye-movement on motion sickness in a virtual environment. In results, we found that motion sickness was significantly decreased by controlling observers' eye-movement with a stationary/moving fixation point. When the extra-retinal and the retinal eye-movements were incongruent during the observer's head moving, the motion sickness was increased for sickness-sensitive observers. These results suggest that we can decrease motion sickness by controlling eye-movements with a stationary/moving fixation point to remove conflict between the extra-retinal and the visual eye-movements. This proposal represents a new approach to decreasing or preventing motion sickness in virtual environments.
