Abstract Hi-tech cabin windows offer exciting opportunities for future aviation industry for cost and design reasons. However, little is known about how displays replacing real windows in an airplane influence passenger comfort. Research here mainly focusses on pilots in flight simulators or not flight-related laboratory virtual environments but not on passengers. One result in these studies is that display latencies may cause symptoms of sickness which can be a crucial factor for comfort. Therefore, the purpose of the present study is to evaluate the impact of latency on passengers’ comfort. 104 participants were recruited as passengers in a full-motion cabin simulator with high-resolution digital displays as hi-tech cabin windows. In three flights the delay between actual motion of the cabin and windows’ outside view was varied (0/0.5/10 s) and four flight segments (take-off, cruise, turbulence and approach) were compared. Inflight and post-flight measures of sickness and estimates of realness were analyzed. Results indicate that only a latency of 10 s had an impact on sickness. Moreover, sickness was mostly characterized by oculomotor symptoms. Inflight measurements revealed that the first flight segments (take-off and cruise) were less affected by long latency than the last flight segments (turbulence and approach). Participants who rated the situation as unreal suffered more from sickness; seating position had no impact on the ratings. The study showed that small latency is a negligible problem for passengers and hi-tech outside view is suitable for future mobility.

机舱内的高科技窗户：显示延迟对乘客舒适度的影响

摘要 出于成本和设计的原因，高科技机舱窗户为未来的航空业提供了令人兴奋的机会。然而，关于显示器取代飞机上的真实窗户如何影响乘客舒适度，我们知之甚少。这里的研究主要集中在飞行模拟器中的飞行员或与飞行相关的实验室虚拟环境中，而不是乘客。这些研究的一个结果是，显示延迟可能会导致疾病症状，这可能是舒适度的关键因素。因此，本研究的目的是评估延迟对乘客舒适度的影响。104 名参与者被招募为全动态客舱模拟器的乘客，该模拟器具有高分辨率数字显示器作为高科技客舱窗户。在三个航班中，机舱的实际运动和窗户外部视野之间的延迟是不同的 (0/0. 5/10 秒）和四个飞行段（起飞、巡航、湍流和进近）进行了比较。分析了飞行中和飞行后疾病的测量以及真实性的估计。结果表明，只有 10 秒的潜伏期才会对疾病产生影响。此外，疾病的主要特征是眼球运动症状。机上测量显示，与最后一个航段（湍流和进近）相比，第一个航段（起飞和巡航）受长延迟的影响较小。认为情况不真实的参与者更容易生病；座位位置对收视率没有影响。研究表明，小延迟对乘客来说是一个可以忽略不计的问题，高科技的外部视野适合未来的出行。分析了飞行中和飞行后疾病的测量以及真实性的估计。结果表明，只有 10 秒的潜伏期才会对疾病产生影响。此外，疾病的主要特征是眼球运动症状。机上测量显示，与最后一个航段（湍流和进近）相比，第一个航段（起飞和巡航）受长延迟的影响较小。认为情况不真实的参与者更容易生病；座位位置对收视率没有影响。研究表明，小延迟对乘客来说是一个可以忽略不计的问题，高科技的外部视野适合未来的出行。分析了飞行中和飞行后疾病的测量以及真实性的估计。结果表明，只有 10 秒的潜伏期才会对疾病产生影响。此外，疾病的主要特征是眼球运动症状。机上测量显示，与最后一个航段（湍流和进近）相比，第一个航段（起飞和巡航）受长延迟的影响较小。认为情况不真实的参与者更容易生病；座位位置对收视率没有影响。研究表明，小延迟对乘客来说是一个可以忽略不计的问题，高科技的外部视野适合未来的出行。机上测量显示，与最后一个航段（湍流和进近）相比，第一个航段（起飞和巡航）受长延迟的影响较小。认为情况不真实的参与者更容易生病；座位位置对收视率没有影响。研究表明，小延迟对乘客来说是一个可以忽略不计的问题，高科技的外部视野适合未来的出行。机上测量显示，与最后一个航段（湍流和进近）相比，第一个航段（起飞和巡航）受长延迟的影响较小。认为情况不真实的参与者更容易生病；座位位置对收视率没有影响。研究表明，小延迟对乘客来说是一个可以忽略不计的问题，高科技的外部视野适合未来的出行。
