One of the PhD candidates upstairs in BioMed (I forget his name, drat)
is measuring the eye movement of infants.  He uses annular, soft contact
lenses (i.e., with the middle cut out) in which are embedded several
turns of fine copper wire; the lenses go in the eyes, and the head goes
in a constant magnetic field.  Voila.

Obviously, this works by measuring movement and not position, but what's
an integration, and when do babies ever sit still, anyway?

P.S.  I really don't know how to contact the guy, and he's probably
graduated and gone by now.  Just thought I'd describe the setup, cuz
I thought it was neat.
