Getting ‘ distance of eyes from screen’ from calibration run

[Flenderson]

Hi All,
We’re using the Pro Max Spectrum, and are doing lots of microsaccade/fixation oriented analysis.
When calibrating before each task, the GUI shows seating distance from the screen.
Does anybody know if the Tobii keeps some record of the seating distance (or, face distance) from the screen in the calibration run data? I know that many people just assume distance of a fixed pre-determined position, but keeping in mind that people certainly move a bit between each tracking run – it would be really helpful to get this automatically from the calibration run..

(BTW, we are using the Titta package to use with Psychtoolbox)

Thanks in advance!!
