Abstract
Many headset devices, such as virtual reality helmets, present visuals that respond to the user's motion, such that a rotation of the user's head causes the visual to be re-rendered from a correspondingly rotated perspective. The lag between the user's motion and the updated rendering from the new perspective may be perceivable even at high framerates, and may induce unpleasant feelings such as vertigo. Instead, headset devices may respond to detected motion by identifying a displacement of the physical location of the visual that causes it to maintain a physical position relative to a stationary reference point. The display is operatively coupled with a displacer, such as actuators or a projection adjustment, that are engaged to displace the display according to the identified displacement and maintain a physical location of the visual relative to the stationary reference point (e.g., until the visual is re-rendered from the updated perspective).
