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.
为了更好地理解在沉浸式虚拟环境中如何感知场景运动，我们在三个实验中的不同条件下测量了场景运动阈值。阈值是在准正弦头部偏航、单次从左到右或从右到左头部偏航、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以及两种场景光照水平下测量的。我们发现，在各种条件下，1）当场景随头部偏航移动时（对应增益<1:0）的阈值大于场景逆头部偏航移动时（对应增益>1:0）的阈值，并且2）阈值随着头部运动的增加而增加。
