- A friend of mine long ago mentioned some guys in california doing it by
- looking at each eyeball with focussed, tight area photoreceptors. The pupil
- moving around changed the reflected light level to each sensor, and a program was
- made to estimate the direction of looking. Blinks were coincidenced out (if more
- than so many detectors were dark, then ignore data, etc.). I have no more details
- than this. I imagine you would only be able to look in one eye and assume the
- other one is also looking at a point. Maybe an easier solution is to use a real
- video lens to look at the eye and run some program to track the splotch of darker
- pixels that show the pupil. ijustdunno. Hope this sets your gears 'a spinnin'.
