The aim of this study was to compare simulator sickness symptoms while participants wore either a virtual reality (VR) or augmented reality (AR) headset. A secondary aim involved comparing how physical motion affects symptoms. During a simulation, participants wore VR and AR headsets while standing on a motion platform and firing at hostile ships under three motion conditions: No Physical Motion; Synchronous Motion, in which the physical and displayed motion were coupled; and Asynchronous Motion, in which the physical motion did not match the display. Symptoms increased over time but were not different with respect to headset or motion. The VR condition had higher accuracy and faster response time to the commence fire instruction. Further research is necessary to determine if this holds under more extreme motion. The use of VR or AR headsets for training under gentle motion conditions is practicable and should be permissible under normal conditions during deployment.
本研究旨在比较参与者佩戴虚拟现实（VR）或增强现实（AR）头显时的模拟器病症状。次要目的是比较身体运动如何影响症状。在模拟过程中，参与者在运动平台上站立并在三种运动条件下向敌方船只开火，同时佩戴 VR 和 AR 头显：无物理运动；同步运动，其中物理运动和显示运动是耦合的；以及异步运动，其中物理运动与显示不匹配。症状随时间推移而增加，但与头显或运动无关。VR 条件对开火指令的准确性更高，响应时间更快。需要进一步的研究来确定在更极端的运动条件下是否如此。在温和运动条件下使用 VR 或 AR 头显进行训练是可行的，并且在部署期间正常情况下应该是允许的。
