FAQ: How do I switch to tracking a different eye?
#1
In the Camera Setup screen on the Host PC, simply click on the eye to track in the camera image. Then, select the “Eye Tracked” at the bottom of the Camera Setup screen by clicking “Left,” Right,” or “Both” (or pressing the "L", "R", or "B" key) so it matches the eye selected.
