I would like to understand, in the world coordinate system, which coordinate system is used as the origin for the eye position and fixation position?
Eye Tracking | MagicLeap Developer Documentation
No, the the headset position is reported located in-between the position of the average of the left and right display referential which ends up being somewhere between the two display and a bit ahead of the users eyes.
To clarify my previous post, I wanted to point out that the fixation point position provided by the API is not relative to the headset but based off of the world origin.
