研究了使用轻型 HMD 作为个人观看系统的效果。当以这种方式使用时，在禁用头部跟踪的情况下，会出现模拟中新颖的感觉冲突：头部运动由前庭系统检测到，但不是由视觉系统检测到。为了调查这种冲突的影响，20 名受试者在使用 HMD 一小时之前和之后报告了一些症状的评级。将结果与同一受试者观看 VDU 时的评分进行比较，其中任务相同但不存在冲突。在这两种情况中，前者产生以下症状的频率明显更高：全身不适、疲劳、头痛、恶心、头晕、胃部意识、眼睛灼热或灼烧感、复视和一般视觉不适。 HMD 结果还与之前的研究进行了比较，之前的研究使用了相同的耳机，但配置为启用了头部跟踪的 VR 应用。令人惊讶的是，考虑到更新滞后、矢量引起的运动线索以及调节/会聚冲突均不存在，因此个人观看配置更频繁地报告了某些症状的增加。 (C) 1997 Elsevier Science B.V.
The effects of using a lightweight HMD as a personal viewing system were examined. When used in this manner, with head-tracking disabled, a sensory conflict which is novel for simulations arises: head movements are detected by the vestibular system but not by the visual system. To investigate the effects of this conflict, ratings of a number of symptoms were reported by 20 subjects before and after they used an HMD for one hour. The results were compared with ratings the same subjects made when viewing a VDU, where the task was the same but the conflict was absent. Of the two conditions, the former produced a significantly greater frequency of increase in the following symptoms: general discomfort, fatigue, headache, nausea, dizziness, stomach awareness, hot or burning eyes, double vision and general visual discomfort. The HMD results were also compared with those from a previous study in which the same headset was used, but configured for VR applications with head-tracking enabled. Surprisingly, given that update lag, cues for vection-induced motion, and accommodation/convergence conflict were all absent, an increase in some symptoms was more frequently reported for the personal viewing configuration.
