Dear MEG Community,
We are building an MEG-lab here in Aarhus, Denmark, and are in the
process of sorting out our peripherals. There is not much in the
"Instrumentation - Peripherals" -section on the website, so I would
like to ask everyone out there with experience on eye-tracking in an
MEG-setting the following questions. I will gladly take on the task of
writing up a summary to be placed on the website for future reference!
I would like to hear about the pros and cons associated with the
MEG-compatible eye-tracking solutions currently on the market. I've
been able to identify three vendors:
1) SMI (http://www.smivision.com/en/gaze-and-eye-tracking-systems/products/iview-x-mri-meg.html)
2) SR Research (http://www.sr-research.com/solutions_meg.html)
3) ASL (http://asleyetracking.com/site/Products/EYETRAC6Series/LongRangeOptic/tabid/69/Default.aspx)
I do realise there are quite a few dimensions along which to compare
these devices, but would appreciate any insight you may have. If
sampling rate were the only deciding factor, there would surely be
only one way to go (2). Another factor could be the light source
("pure" IR vs. "ups-there's-a-little-visible-light-too") illuminating
the iris. We would also be keen on hearing if
fMRI-compatibility/-usability has had anything to do with your choice
of MEG eye-tracker.
Btw: Our Elekta Neuromag-system will be installed in January 2011.
Best regards,
Chris
