Motion sickness (MS) poses challenges for individuals affected, hindering their activities and travel. This study investigates the effect of a visual dynamic device, forming an artificial horizon plane, on symptoms and physiological changes induced by MS. This device consists of vertical light-emitting diodes whose illumination varies according to the boat's movements. Fifteen subjects with moderate-to-severe MS susceptibility were exposed to a seasickness simulator with and without the device. Symptoms were assessed immediately after exposure. Time spent in the simulator, heart rate, and temperature were also recorded. Symptom intensity at the end of the experience did not differ, but the time spent in the simulator was significantly longer with the device (+46%). Variations in heart rate were also observed. The device delays symptom onset and can be used as a tool against MS. Further research is needed to evaluate its effects, for example, during more prolonged exposure to MS-inducing stimuli.
运动病（MS）给受影响的个体带来挑战，阻碍他们的活动和旅行。本研究调查了一种视觉动态设备（形成一个人工地平线平面）对 MS 引起的症状和生理变化的影响。该设备由垂直发光二极管组成，其照明根据船的运动而变化。15 名具有中度至重度 MS 易感性的受试者在有和没有该设备的情况下暴露于晕船模拟器中。在暴露后立即评估症状。还记录了在模拟器中的时间、心率和体温。体验结束时的症状强度没有差异，但使用该设备时在模拟器中花费的时间明显更长（+46%）。心率也有变化。该设备可延迟症状发作，可作为防治 MS 的工具。需要进一步研究来评估其效果，例如，在更长时间暴露于引起 MS 的刺激时。
