yanscheu Posted October 1, 2019 Share Posted October 1, 2019 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? @Corvus @Daniel_Y Link to comment Share on other sites More sharing options...
Daniel_Y Posted October 3, 2019 Share Posted October 3, 2019 What 2D system your are refering to? LCD panel? Link to comment Share on other sites More sharing options...
yanscheu Posted October 5, 2019 Author Share Posted October 5, 2019 Yes, I'm refering to the Vives double 1440 x 1600 pixel screen. @Daniel_Y Link to comment Share on other sites More sharing options...
Daniel_Y Posted October 8, 2019 Share Posted October 8, 2019 @yanscheu You could consider your gaze vector mapping to HFOVxVFOV is ~110 degree covering 1440x1600 resolution per eye although it is not precisely because it is distorted image shown on LCD panel via a Fresnel lens to your sight.
