These are the GT gaze labels in the eye coordinate system. You can find the formulas in our paper (Eq. 1).

@erkil1452 I see the formulas, so we can use the code in #30 to compute the GT gaze labels?
there are some other questions I want to ask:
- If our camera only can get the 2d coordinate, then how to covert the 2d coordinate to 3d coordinate?
- Whether gaze360 algorithm can only use in the datas in 3d coordinate format?
- Is there some good algorithms can use in the datas in 2d coordinate format?

Yes, you can use these code snippets to convert a gaze vector expressed in world coordinates into the (network's) eye coordinates (and back).
- It is not clear what your intention is. In case you want to reproduce our annotation procedure, you need to first determine 3D location of the eyes and 3D position of the gaze target in some world coordinate system of your choice. There is no general way how to convert 2D coordinate into 3D without additional information about the scene.
- Our method is developed for 3D gaze prediction. You can feasibly formulate your own problem definition where the prediction happens in 2D by projecting the 3D labels on a 2D manifold of your liking.
- There are many 2D gaze predictors. I can shamelessly refer you to our own iTracker dataset and method: https://gazecapture.csail.mit.edu/
