Pupil Diameter

[kimarionizetha]

Hi every one,
Does any one knows how to get pupil diameter from the raw data in the eye proof tool?
I will appreciate for any help.


Best Regards.

Hi

Unfortunately, pupil diameter is currently not available in the raw data export tool.

Hi,

I have a question about pupil size. I have read from the forum that pupil sizes are recorded as pixel by Eye Tribe eye tracker.
But, I want to convert it to mm.
For the conversion is it enough to multiply pixel value by 0.264583 ? (because of 1 px = 0.264583 mm).
Or, is there another formula for calculation, if the person is 70 cm far from eye tracker and monitor.

Can you please help,
Many Thanks.
