Virtual environment (VE) users often experience varying levels of Nausea, Oculomotor Discomfort, and Disorientation after VE exposure. Is there a difference in symptoms for people who end their VE exposure prematurely compared to those who, though suffering discomfort, do not? Sickness data from 29 participants who dropped out of their experimental study (dropouts) and 29 of the most severely sick of those who completed their study (finishers) were compared. Though there was insufficient evidence to conclude that the two groups differed in terms of Total Severity, dropouts experienced significantly more Nausea than did finishers. Relative subscale rankings indicate the most severe symptom for dropouts was primarily Disorientation followed by Nausea. For finishers the most severe symptom was also Disorientation but followed essentially equally by either Nausea or Oculomotor Discomfort. Ramifications of these findings are discussed.
