人们普遍认为，在甲板下工作的水手晕船的发生率高于在驾驶台上以地平线为视觉参照的水手。这项研究调查了投射的人工地平线作为预防晕船的一种手段可能产生的有益效果。在三种实验条件下，12名受试者在倾斜的房间中暴露在角运动中：a)窗户被遮盖，不允许外界的视觉参照；b)窗户不遮盖，因此可以部分看到环境；c)窗户被遮盖，地平线被旋转的激光投射到墙上。受试者在每种情况下暴露35分钟，同时执行不同的计算机化任务。幸福感和表现随着暴露时间的延长而降低。这些影响在“封闭机舱”的情况下表现得很明显。在“人工地平线”和“窗口”条件下晕动病症状较少。视觉参照物的存在防止了在“封闭机舱”条件下的性能下降。这项研究的结果表明，投射的地平线可能会减轻海军舰艇上的晕船，从而改善水手在海上的表现。
It is generally agreed that the incidence of motion sickness in sailors working below deck is higher than in sailors who have the horizon as a visual reference on the bridge. This study investigated the possible beneficial effect of a projected artificial horizon as a means to prevent seasickness. Twelve subjects were exposed to angular motion in a tilting room under three experimental conditions: a) With the windows covered, allowing no visual reference from the outside world; b) With the windows uncovered, thus allowing a partial view of the environment; and c) With the windows covered and a horizon projected on the walls by a rotating laser beam. Subjects were exposed for 35 min in each condition while performing different computerised tasks. There was a reduction in well-being and performance as a function of exposure time. These effects were clearly shown in the "closed cabin" condition. There were less motion sickness symptoms in the "artificial horizon" and "window" conditions. The presence of a visual reference prevented the decrement in performance found in the "closed cabin" condition. The results of this study suggest that a projected horizon might alleviate motion sickness aboard naval vessels, and thus improve the performance of sailors at sea.
