I think the size of the frames will occasionally interfere too. I find the bigger the frames the better. Less chance that the frame itself obstructs the infrared eye gaze component. Little "cat eye" frames seem to be the worst.

Hi Kelly

Yes these could be issues, but another possible cause might anti-reflective coatings on the lenses…

Subject: Tobii I-15 eyegaze with glasses

Hey all:

I was wondering if anyone had any trouble shooting ideas for glasses with the Tobii I-15 eye gaze system. I have a patient who has metal rimmed glasses who was looking at eye gaze, but we had difficulty calibrating him. I know that metal rimmed glasses and progressive lenses can be a problem with PRC eyegaze devices. Are there the same constraints with the Tobii devices? Also, any trouble shooting ideas for glasses would be welcomed. Thanks so much!
