The Eye Tribe

What it means to write files in the api console - the pupilsize in two columns? It is the pupil size in pixels ?? or something else?

Ok, I saw that information about pupil there, but what are they measured, what scale to mm pixel ??

Pixels. Conversion to mm depends on distance from device. That's why we call it a relative value (to the current position).

Ok
If distance from ET to monitor = 700 mm/ a scale for 1 mm? There is a formula unit conversion?

Hi,

I have a question about pupil size. I have read from the forum that pupil sizes are recorded as pixel.
But, I want to convert it to mm.
For the conversion is it enough to multiply it by 0.264583 ? (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.
