Display systems and methods for determining registration between a display and a user's eyes

A computer-implemented method for controlling a head-mounted display of a display system, the display configured to project light into an eye of a user to display virtual image content, the method comprising:

• defining a registration volume relative to the display based on one or more parameters;
• determining a position of the eye based on images of the eye obtained with one or more eye-tracking cameras of the display system;
• determining whether the position of the eye is within the registration volume;
• and
• controlling operation of the display based on determining whether the position of the eye is within the registration volume, wherein controlling operation of the display includes causing the display to boost a brightness of a plurality of pixels of the display relative to other pixels of the display, and wherein the plurality of pixels with a boosted brightness comprise pixels expected to undergo perceived dimming while the position of the eye is not within the registration volume.

One or more non-transitory computer-readable storage media storing instructions that, when executed by at least one processor, instruct the at least one processor to perform operations for controlling a head-mounted display of a display system, the display configured to project light into an eye of a user to display virtual image content, the operations comprising:

• defining a registration volume relative to the display based on one or more parameters;
• determining a position of the eye based on images of the eye obtained with one or more eye-tracking cameras of the display system;
• determining whether the position of the eye is within the registration volume;
• and
• controlling operation of the display based on determining whether the position of the eye is within the registration volume, wherein controlling operation of the display includes causing the display to boost a brightness of a plurality of pixels of the display relative to other pixels of the display, and wherein the plurality of pixels with a boosted brightness comprise pixels expected to undergo perceived dimming while the position of the eye is not within the registration volume.
