Abstract

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), and (2) thresholds increase as head motion increases.
