So there isn’t much more to it than getting a good resolution image of the eye from any distance, every millisecond. Precision is the issue because we are mostly moving our eyes in about 8 directions, there’s no precision because we don’t know how to measure focusing of our eye lens with a camera yet (unless that too is just a matter of getting a picture). Squinting would be the closest thing to physically expressing focusing. So the camera needs to know I’m looking left with my eye, followed by a squint to achieve precision. Seems stressful though. Gonna need AI just to do noise cancelling of involuntary things your eyes do like pupil dilation, blinking.
