Profile of cybersickness and balance disturbance induced by virtual ship motion alone and in combination with galvanic vestibular stimulation (GVS) remained unclear. Subjects were exposed to a ship deck vision scene under simulated Degree 5 or 3 sea condition using a head-mounted virtual reality display with or without GVS. Virtual ship motion at Degree 5 induced significant cybersickness with symptom profile: nausea syndrome > central (headache and dizziness) > peripheral (cold sweating) > increased salivation. During a single session of virtual ship motion exposure, GVS aggravated balance disturbance but did not affect most cybersickness symptoms except cold sweating. Repeated exposure induced cybersickness habituation which was delayed by GVS, while the temporal change of balance disturbance was unaffected. These results suggested that vestibular inputs play different roles in cybersickness and balance disturbance during virtual reality exposure. GVS might not serve as a potential countermeasure against cybersickness induced by virtual ship motion.

单独由虚拟船舶运动和结合前庭电刺激 (GVS) 引起的网络病和平衡障碍的概况仍不清楚。使用带或不带 GVS 的头戴式虚拟现实显示器，受试者在模拟 5 级或 3 级海况下暴露于船舶甲板视觉场景。5 级的虚拟船舶运动会导致显着的网络病，其症状是：恶心综合征 > 中枢性（头痛和头晕）> 外周性（冷汗）> 流涎增加。在单次虚拟船舶运动暴露期间，GVS 加重了平衡障碍，但除冷汗外并未影响大多数网络病症状。重复暴露诱发的网络病习惯被 GVS 延迟，而平衡障碍的时间变化不受影响。这些结果表明，前庭输入在虚拟现实暴露期间在网络病和平衡障碍中发挥不同的作用。GVS 可能无法作为针对虚拟船舶运动引起的网络病的潜在对策。
