How can i get eyeposition by Unity SDK?

[Matsumoto]

Hi.
I’d like to get the position of the eyeballs relative to the screen.
How can i get it by Unity SDK?

Does the position include the coordinate(x, y, z)?

Hi!

We decided to remove eyeball positions stream in the upcoming API update. Instead you will be able to access head pose stream (x, y, z, yaw, pitch, roll) which will come in higher precision than the old eyeball position stream. Is it something that would suit your needs?

Thank you for your reply.
Which SDKversion do you remove eyeball positions??
Can i use eyeball positions by v2.0 Beta?

Hi!

There’s a reason we removed eyeball positions. Unfortunately 3d eyeball position signal is unstable and is significantly worse than gaze point signal, so we don’t want developers to utilize it. We might add it back in the future if we manage to make it better. If you tell us more about your application I will try to help you solving the particular problem.

It was removed with v2.0 Beta, so you cannot use eyeball positions with that version.

Hi @Jenny
Thank you for your reply.
I will consider it by Alex’s suggestion.

Hi @Alex,
Thank you for your suggestion.

I’d like to develop app which change picture by Right-eyeball position(x, y, z).
It’s not eye-gaze(x, y).

Can i calculate Right-eyeball position(x, y, z) by head-pose(x, y, z)?
Or, is there another method?
