The study investigates the following two: (i) what types of visually-simulated body motion tends to elicit stronger motion sickness, and (ii) the effects of visual pattern on visually-induced motion sickness. To do this, we showed observers two different visual scenes, random-dots and ordinary scene, with six different types of visual motion corresponding to virtual body movements of rotation and translation along three orthogonal axes. The results showed that: (a) roll motion yielded the largest subjective score of both motion sickness and vection, and (b) no difference of the sickness between the two different scenes used for eliciting the sickness. We speculated that cognitive information, such as information of gravitational direction included in the ordinary scene, does not affect the sickness at least for those visual simulations of simple body motion.
