I wonder if this concept (corneal reflection photography) can be used for an
eye-tracking interface for computers. Can you match the segment of the image
of the corneal reflection that is above the pupil with what is on the screen
to figure out where/at what the user is looking?

It's good to understand what "resolution" actually means when considering
these types of problems. Suppose you have 2 dots close together. The ability
of your camera to "see" (resolve) 2 dots as opposed to a single blob is a
function of the sensor and the lens.

All the sensor resulution in the world is not going to let you resolve
something if the lens has already blurred the image.

While sensors have become relatively cheap, optics have not. I think physics
alone makes it impossible to have a camera phone lens that resolves anywhere
near what these XX megapixel image sensors could theoritically resolve.
