Abstract
The purpose of this paper is to report the comparison of two independent measures of susceptibility to motion sickness, the Motion Sickness History Questionnaire and the Motion Sickness Susceptibility Questionnaire – Short Version. Twenty-nine subjects (15 male) participated in a repeated measures study in which they were exposed to two different latency conditions in a Head-Mounted Display (HMD): constant (70 ms) and varying (70 ms – 270 ms). Sickness levels increased significantly over time in both conditions. Participants began the study with minimal symptoms, progressing to problematic levels by the end of the blocks of trials. Prior to the study all participants completed both the MSHQ and the MSSQ-S. Peak sickness levels were strongly correlated with MSSQ-S, Pearson’s r =.45, p = .01. The MSHQ susceptibility scores did not significantly correlate with peak sickness levels. This indicates for this study the MSSQ-S more accurately predicted a participant’s susceptibility to motion sickness than the MSHQ.
