Patent 10572764 was granted and assigned to Google on February, 2020 by the United States Patent and Trademark Office.
Techniques of displaying video in an HMD include performing an adaptive rendering operation to produce a transition between stereo and non-stereo rendering of objects in a virtual environment during eye saccade. Because viewers generally have low visual perception performance during eye saccade, the viewer will not notice this transition as much and will not experience as much motion sickness.
