For the purpose of a study I'm trying to use the vive pro eye (and the sranipal sdk) to get eye tracking data while showing an existing VR-Browser-application in the glasses (using SteamVR).
With a modified version of the c++ example l'm abel to record the 3d unit vectors of the users gaze ray. But I actually need (2d) pixel coordinates of the users point of regard.
Is there a way to calculate the point of regard from gaze ray? Or am I missing something else?
