Virtual and augmented reality systems and methods
First Claim
1. A display system comprising:
- a head-mountable display comprising;
a waveguide stack comprising a plurality of waveguides configured to provide image content on a plurality of depth planes, each of the plurality of waveguides of the waveguide stack having optical power and being configured to project light into a same eye of a viewer to display image content on an associated depth plane of the plurality of depth planes,wherein any image content provided by the head-mountable display is disposed on one of the plurality of depth planes, wherein each of the plurality of depth planes is at less than optical infinity.

Abstract
Methods and systems are disclosed for presenting virtual objects on a limited number of depth planes using, e.g., an augmented reality display system. A farthest one of the depth planes is within a mismatch tolerance of optical infinity. The display system may switch the depth plane on which content is actively displayed, so that the content is displayed on the depth plane on which a user is fixating. The impact of errors in fixation tracking is addressed using partially overlapping depth planes. A fixation depth at which a user is fixating is determined and the display system determines whether to adjust selection of a selected depth plane at which a virtual object is presented. The determination may be based on whether the fixation depth falls within a depth overlap region of adjacent depth planes. The display system may switch the active depth plane depending upon whether the fixation depth falls outside the overlap region.
