Claim 0:
1. A wearable display system, comprising:
a head-mounted display configured to present virtual content by outputting light to an eye of a wearer of the head-mounted display;
at least one light source configured to direct light toward the eye of the wearer; a right eye tracking camera configured to capture a first plurality of visual data of a right eye of the wearer at a first sampling rate;
a left eye tracking camera configured to capture a second plurality of visual data of a left eye of the wearer at a second sampling rate, the second plurality of visual data captured during different sampling times than the first plurality of visual data; and
processing electronics communicatively coupled to the head-mounted display and to the right eye tracking camera and left eye tracking camera, the processing electronics configured to:
based on at least some visual data of the first plurality of visual data and the second plurality of visual data, estimate visual data of the right eye at a sampling time during which visual data of the first plurality of visual data is not being captured;
based on at least some visual data of the first plurality of visual data and the second plurality of visual data, estimate visual data of the left eye at a sampling time during which visual data of the second plurality of visual data is not being captured;
determine eye movement of at least one of the right eye or the left eye, wherein a determination of the eye movement of the right eye is based on at least some of the estimated visual data of the right eye and at least some visual data of the first plurality of visual data of the right eye, and wherein a determination of the eye movement of the left eye is based on at least some of the estimated visual data of the left eye and at least some visual data of the second plurality of visual data of the left eye; and
cause the head-mounted display to present virtual content based on the eye movement of at least one of the right eye or the left eye.
