Single & common mean gaze cursor for both eyes

Hi,

 

What's the best way to have a single gaze cursor, which would be the common/mean/average point of the both eyes, instead of having it separately for both left and right eyes?

Does FOVE SDK for Unity 3D provide any script or method for that?

Will it have any repercussions or any unwanted outcomes if its done this way?

 

Thanks in advance!

  Hi Junaid,

  Our underlying C/C++ SDK and the Unity plugin expose getGazeConvergence() which returns what we call the "Cyclops vector" or, essentially, the best vector to use for your ray-traces. It also gives a very approximate distance, which you can use for disambiguating multiple hits on a raytrace.

  Currently it's an averaged vector in the middle, but it could be the better of the two eye vectors, or any other kind of average in the future, if new research yields more accurate techniques. Hence the fact that there's both an offset and a direction in the resulting ray.
