So what's the eye image? Is the lens of the headset? Can not understand the eye image by the eye tracking camera, does they use another coordinate syetem. I know the gaze origin and gaze direction is based on HMD coordinate system. I have a question which is can we get the gaze origin based on the pupil position in sensor area?

 

[Coordinate of gaze origin and direction]

Dear @Daniel_Y

Hello,  how I can convert the Pupil position to HMD coordinate system, cause I now I have to compare my method with other peaple, and they did not provide the gaze origin and gaze direction in their collected data. I need to know the gaze origin and gaze direction in order to compute the position in global coordinate system. They used HTC VIVE PRO.
