在头盔显示器(HMD)暴露期间，模拟器病(SS)的体验仍然是一个问题。这两个实验的目的是在通过头盔显示器观看真实的实时视频场景时，检查延迟对SS的影响。在两个实验中都执行了物体搜索任务。实验1检测了0和200毫秒的延迟，实验2检测了0、145和300毫秒的延迟。SS没有作为延迟的函数而不同。然而，在两个实验中，SS随着持续暴露时间的增加而增加。在实验1中，第一个实验阶段的SS大于第二个实验阶段。在实验2中，戴上HMD和不戴HMD的对照组之间SS没有差异。这可能是由于对反复暴露于令人恶心的刺激的适应。这种适应可能混淆了实验1的延迟效应。为此，第二个实验增加了会话间隔。实验2的间隔时间从实验1的7天增加到11-14天。然而，实验2没有发现延迟或会话的影响。这些结果表明，SS不是随着延迟而增加，但暴露时间增加了SS。此外，仅进行重复的头部运动可能会引发SS的症状。正如其他研究人员报告的那样，似乎对晕动病刺激的适应可以发生在间歇时间长达7天的情况下，但不能发生在11-14天。HMD VES的其他特征需要检查，因为SS的发生和延迟似乎不是像以前认为的那样强烈的因果因素。(C)2011爱思唯尔B.V.保留所有权利。
The experience of simulator sickness (SS) during head-mounted display (HMD) exposure continues to be a problem. The aim of these two experiments was to examine the effect of delay on SS while viewing a real, live video scene via an HMD. An object search task was performed in both experiments. Experiment 1 examined 0 and 200 ms of delay and Experiment 2 examined 0,145, and 300 ms of delay. SS did not differ as a function of delay. However, SS increased as duration exposure increased in both experiments. In Experiment 1, SS was greater during the first experimental session than the second. SS did not differ between those who donned an HMD and a No HMD control condition in Experiment 2. It is possible that this is due to adaptation to repeated exposure to the sickening stimulus. This adaptation could have confounded the delay effects from Experiment 1. For this reason, a second experiment with an increased intersession interval was conducted. Intersession intervals for Experiment 2 were increased to 11-14 days from 7 days in Experiment 1. However, no effect of delay or session was found in Experiment 2. These results suggested that SS does not increase as a function of delay, but exposure duration increases SS. Also, performing repetitive head movements alone may have elicited symptoms of SS. As reported by other researchers, it appears that adaptation can occur to motion sickness stimuli with intersession intervals of up to 7 days, but not with 11-14 days. Other characteristics of HMD VEs need to be examined because SS occurs and delay does not appear to be as strong of a causal factor as once thought. (C) 2011 Elsevier B.V. All rights reserved.
