Hi,
Using the Inquisit plugin for Tobii, we are having trouble understanding the eye tracking data file generated. The Tobii SDK explains some of the columns, but others it does not. Question: Could you tell us the difference between (using left eye as an example):
leftpixelx,y,z compared to focuspixelx,y compared to leftgazex,y,z compared to lefteyex, y, z ?
Judging from the output files, I assume it is not possible to record saccadic eye movements directly (but we would have to define these post-data acquisition), right?
Thank you for any help on this matter.
Cheers,
Esther

Does anyone have any information on this? It would be really helpful to get some hints (the same holds for the outputs produced by your Tobii samples) . Please also let me know if you require any additional details...
Thanks,
E.

We have published a documentation topic here that will hopefully answer those questions:

You did not miss it, it has only been published recently. Sorry that wasn't sufficiently clear in my previous reply.

Thanks for the posting of the document. I do, however, have one question that I do not see answered in that document, and that's what the coordinates mean. Is it the same as Inquisit's default coordinate system, with (0, 0) meaning the top left corner?

0 0 is top left
