Dear Lukas,
We have used the MR-compatible eye tracker from Cambridge
Research Systems for some time now. I presume that this system is
the least expensive solution in the market. The quality of the
acquired data is normally quite good, but can be affected by subject
motion. Subjects with glasses may pose problems.
A good mount for the mirror and tracker is essential. Dependent on
what kind of scanner and coil you own, Cambridge may already
have an appropriate design. Otherwise you can make your own
mount or collaborate with Cambridge to design a new one.
Calibrating may be a bit difficult at first, but once you have an
efficient procedure and get the hang of it, you can do it within 5
minutes.
Kind regards,
Mathijs Raemaekers

Dear list members!
Does anybody have experience with eye tracking devices for fMRI
experiments? Any recommendations or comments?
Many thanks in advance,
