Hi,
I'm using the SRanipal SDK in Unity to get eye tracking data from the HTC Vive Pro Eye headset.
I have a question regarding the pos_sensor_Lx, pos_sensor_Ly, pos_sensor_Rx, pos_sensor_Ry variables (normalized by default in [0,1]). It is generically said that they rapresent the pupil position.
I tried to follow with the Vive Pro Eye a square figure and then overlay the plot of the pupil position for each eye as in the picture attached below (where the image in the background represents the left and right eye view as seen in the Unity game view). However the result obtained does not convince me, I expected to have the plot overlayed on the red square.
So my question is: what do (pos_sensor_Lx, pos_sensor_Ly), (pos_sensor_Rx, pos_sensor_Ry) represent? Are them the position of the pupil on the telecamera or do they indicate where the user is watching on the headset screen?
Are the variables I have to consider to get the gaze coordinates or I have to consider something else?
Thank you!
