Hi Dieter, just to make sure: you’re using the EyeX SDK for Unity, right?
If you do I’m sorry to say that there is no straightforward way to find the angles just yet. You would need the eye positions and the gaze point, both in space coordinates, but currently there is only the eye positions. We’re planning to provide the gaze point in space too, so if you have the patience it should be available in a few weeks’ time.
If you’d rather get started right now you can download the EyeX SDK for .NET and look at how to read engine states. You can use that to find the screen geometry and calculate the gaze point in space yourself, and from there it’s relatively easy to compute the angles.
