I need some help.
I need to get?an movement of pupils in real worls's distance unit(mm/inch) or angle unit(degree) using Vive pro eye.
So, I check the SRanipal SDK Doxygen file and find the description about GetPupilPostion API.
But I have a problem.
In Doxygen, pupil position is printed by (x,y)?coordinate.
However, I need to caculate the variation about pupil position by real unit(cm, mm, inch).?
How can I get It?
In other words, I'd like to know if 1, -1 in the?GetPupilPosition() is relative offset or absoulte offset by each person.
