Аннотация:Virtual Reality (VR) is considered one of the most influential technologies of the last decade. However, simulator sickness (SS) remains a significant limitation of its use. We hypothesizedthat forming the turn motor skill in VR can reducethe severity of SS. In this work the participant was motionless in the center of a virtual optokinetic drum which was painted in black and white vertical stripes. He could turn round or rotate the wall of the drum only with the help of the controller. Two groups of participants (N = 40) trained different movements for 3 days. One group (N = 20) trained to turn to the vertical red stripe on the wall of the optokinetic drum and point to it with the controller. The other group (N = 20) trained to rotate the vertical wall of the optokinetic drum so that the red bar was directly opposite the controller. The severity of SS was assessed based on the results of heart rate, tapping test, reverse counting with subtraction and Simulator sickness questionnaire indicators. It was found that the severity of SS was significantly higher in the group forming the motor skill of space level than in the “action-level” group (p < 0.001). However, it significantly decreases with training, and in both test tasks in this group, SS is weakly expressed (p > 0.001). In the second group the severity of SS was initially lower, but no dynamics were observed during training. SS was strongly pronounced in this group in the spatial test task. Thus, movement training in VR at the leading level of space prevents the development of SS.
