I want to know what the three coordinates of vergence in eye movement indicators represent and how they are calculated.
Hi @carriefox517,
Thank you for reaching out regarding this question. I have reached out to our team to get more information and I will report back as soon as I learn more.
Best,
El
The vergence point is a 3D point (x,y,z) that is the least squares intersection of the left and right eye gaze vectors.
The eye tracker computes it relative to the headset (the "rig") but The API transforms it to world coordinates on the way out.
