Hi,
You may want to take a look at the Arrington Research Precision Head
Positioner.
It consists of a nose bridge / forehead rest as well as a chin cup to
provide maximum stability without the discomfort of a bite bar.
Independent axes of movement provides quick and accurate adjustment to
accomodate a wide variety of face and head shapes and sizes.
Photographs and prices can be found on our web site.

Arrington Research initially sold the Precision Head Positioner only as
part of the ViewPoint EyeTracker hardware and software system. As many
people who saw it on the ARI web site or at conferences wanted to buy
just the head positioner, it is now sold as a separate product.
