Abstract The purpose of this study was to determine how latency in a head-mounted display (HMD) affects human performance. Virtual environments (VEs) are used frequently for training. However, VEs can cause simulator sickness. Prior work in our laboratory has examined the role of varying latency in simulator sickness. However, the effect of varying latency on task performance has not been examined. Subjects participated in a repeated measures study where they were exposed to two different latency conditions in an HMD: constant (70 ms) and varying (70–270 ms). During each HMD exposure, subjects used a laser pointer to repeatedly “shoot” at laser targets while accuracy and time-to-hit were recorded. Subjects scored fewer hits and took longer to hit targets in the varying latency condition. These findings indicate that individuals exposed to varying latency perform worse than individuals exposed to a lower constant latency.

头戴式显示器中的任务性能：不同延迟的影响

摘要 本研究的目的是确定头戴式显示器 (HMD) 中的延迟如何影响人类表现。虚拟环境 (VE) 经常用于培训。但是，VE 会导致模拟器病。我们实验室之前的工作已经检查了不同延迟在模拟器疾病中的作用。但是，尚未检查不同延迟对任务性能的影响。受试者参与了一项重复测量研究，他们在 HMD 中暴露于两种不同的潜伏条件：恒定（70 毫秒）和变化（70-270 毫秒）。在每次 HMD 曝光期间，受试者使用激光笔反复“射击”激光目标，同时记录准确性和击中时间。在不同的潜伏期条件下，受试者的命中率较低，击中目标的时间更长。
