I have used EOGs for years, and I can confirm that the accuracy is not very
good. Also, you will runinto potential problems with DC, which here
translates into absolute positions, because the EOG shows drifts over time.
If these problems can be solved, then it would be by Dr. Frank Behrens in
Germany.
I think he has gone as far with EOPGs as anyone. You can contact him at
"fbehrens@wotan.CS.Uni-Magdeburg.De". He may even have experience with EOGs
in driving situations, - I am not sure, though.
Good luck.
