In order to better understand how scene motion is perceived in immersive virtual environments, we measured scene-motion thresholds under different conditions across three experiments. Thresholds were measured during quasi-sinusoidal head yaw, single left-to-right or right-to-left head yaw, different phases of head yaw, slow to fast head yaw, scene motion relative to head yaw, and two scene-illumination levels. We found that across various conditions (1) thresholds are greater when the scene moves with head yaw (corresponding to gain <1.0) than when the scene moves against head yaw (corresponding to gain >1.0), and (2) thresholds increase as head motion increases.

沉浸式虚拟环境中头部偏航期间的场景运动阈值

为了更好地了解在沉浸式虚拟环境中如何感知场景运动，我们在三个实验中测量了不同条件下的场景运动阈值。在准正弦头部偏航、单个从左到右或从右到左的头部偏航、头部偏航的不同阶段、从慢到快的头部偏航、相对于头部偏航的场景运动和两个场景照明级别期间测量阈值. 我们发现，在各种条件下，（1）当场景移动时头部偏航（对应于增益<1.0）时阈值大于场景移动时头部偏航时（对应于增益>1.0），并且（2）阈值随着头部而增加运动增加。
