Abstract
Stereoscopic display misalignments contribute to a number of adverse side effects in head-mounted displays that render world-locked or body-locked content, including motion sickness, visual discomfort, and distorted depth perception. This disclosure presents techniques for correcting horizontal misalignments by leveraging the perceptual discrepancies arising from these distortions. Specifically, the difference in perceived distance of a virtual image under binocular (stereoscopic) and monocular viewing conditions is used to detect and rectify misalignments. User input is obtained regarding the distance between two images of the same object, where one image is rendered stereoscopically and one image is rendered monocularly. The binocular disparity of the display is adjusted until the object in the stereoscopic image appears at the same distance as the monocular image. This disparity value ensures correct horizontal display alignment in stereoscopic displays, mitigating adverse side effects like motion sickness and visual discomfort.
