Hi Sol: how about sending an email to this mailing list underlying that
EL II does not require a chin-rest because of the head-movement
compensation system (though a chin-rest generally improve data quality)?
Thanks,
Francesco

For some applications a headrest might be better. We sell a simple
folding chair with a detachable, adjustable headrest. We include this
chair and headrest with each eye tracking system that we sell, but we
can also sell them individually for use with other systems. Current
pricing is $200 plus shipping in the U.S.

Dear Dr. Weigelt:
according to recent experiments we made I would suggest to apply a chin
rest during subject's calibration. It seems to be difficult for many
people to maintain the head in a fixed position which is neccessary
during this phase.

Morten Grandt
P.S. Regards to your colleague, Martin Schütte
