| summary | Motion sickness is an increasing problem in simulation, virtual environments, interactive technologies, and mobile devices. One important factor in motion sickness is the existence of a large sex difference. In most situations, women are more likely than men to become motion sick. This has been true for thousands of years (e.g., in sea travel), but there has been little research on possible sex differences in contemporary interactive display systems. Exploring general issues in the etiology of motion sickness, we have shown that the subjective symptoms are preceded by distinctive patterns of postural activity. This effect exists in the context of seasickness, video games, head-mounted displays, flight simulation, and mobile devices. In the present study, standing participants were exposed to visual oscillation in a moving room. Among 114 participants, the proportion of women reporting sickness (38%) was greater than men (9%), confirming that the sex difference extends to purely visual motion. During exposure to room motion, postural activity differed between participants who later reported motion sickness and those who did not, but did not differ between women and men. However, we also measured postural kinematics before participants were exposed to experimental motion. In these data postural sway differed between the sexes, and between those who later became sick and those who did not, in a statistically significant interaction. The results offer new insight into the nature and origin of sex differences in motion sickness, and have implications for the design and use of health-oriented serious games. |
