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.

Adaptive stereo rendering to reduce motion sickness

A display device, such as a head mounted device (HMD), displays a virtual scene. The display device includes a motion tracker for detecting rotation and/or translation of the display device. The display device also includes a processor that is configured to determine, in response to the detected, an orientation of the display device relative to a plurality of world-aligned viewing frustums that are stationary relative to the virtual scene. The processor is also configured to identify a set of those world-aligned viewing frustums that overlap with an output field of view. The processor is further configured to render pixels of the set of those world-aligned viewing frustums that overlap with an output field of view and upsample the rendered pixels to generate values of display pixels for presentation by the display device.
