我们的目的是扩大对晕动病的了解，晕动病是一种因沉浸在移动的计算机生成的虚拟现实中而引起的晕动病的亚型。 14 名健康受试者连续 3 天通过头戴式显示器 (Oculus Rift) 体验了 15 分钟的过山车之旅。实验过程中测量心率、呼吸、手指和前额皮肤电导；骑行期间的主观恶心评级以及骑行前、骑行后立即以及骑行后 1、2 和 3 小时的晕动病评估问卷对此进行了补充。从三个维度分析生理测量结果：骑行时间、与主观恶心评级的关联以及实验日期。前额以及较小程度的手指阶段性皮肤电导活动显示出与报告的恶心等级相关，而其他测量参数的变化主要与虚拟骑行开始期间的自主神经唤醒有关。在主观症状评分和耐受挑衅持续时间中观察到显着的习惯化。后者从第一天的 7.0 +/- 1.3 分钟增加到第三天的 12.0 +/- 2.5 分钟 (p < 0.05)；这与恶心上升斜率降低相关，从第一天的 13 03 单位/分钟减少到第三天的 0.7 +/- 0.1 单位/分钟 (p < 0.01)。此外，重复暴露的习惯也通过骑行后的总症状评分来确定：从第一天的 1.6 +/- 0.1 下降到第三天的 12 0.1 (p
Our aim was to expand knowledge of cybersickness a subtype of motion sickness provoked by immersion into a moving computer-generated virtual reality. Fourteen healthy subjects experienced a 15-min rollercoaster ride presented via a head-mounted display (Oculus Rift), for 3 consecutive days. Heart rate, respiration, finger and forehead skin conductance were measured during the experiment; this was complemented by a subjective nausea rating during the ride and by Motion Sickness Assessment Questionnaire before, immediately after and then 1, 2 and 3 h post-ride. Physiological measurements were analysed in three dimensions: ride time, association with subjective nausea rating and experimental day. Forehead, and to a lesser extent finger phasic skin conductance activity showed a correlation with the reported nausea ratings, while alteration in other measured parameters were mostly related to autonomic arousal during the virtual ride onset. A significant habituation was observed in subjective symptom scores and in the duration of tolerated provocation. The latter increased from 7.0 +/- 1.3 min on the first day to 12.0 +/- 2.5 min on the third day (p < 0.05); this was associated with a reduced slope of nausea rise from 13 03 units/min on the first to 0.7 +/- 0.1 units/min on the third day (p < 0.01). Furthermore, habituation with repetitive exposure was also determined in the total symptom score post-ride: it fell from 1.6 +/- 0.1 on the first day to 12 0.1 on the third (p
