Gaze Points are Offset in Unity with using Eye Tracker 4C

[Janek Stegemann]

Hey,

I just installed Unity and the Eye Tracking SDK.
I tested a DemoScene and other projects with the Eye Tracker 4C and recognized that the shown gaze Points are Offset to the lower right.
I changed the Display scale around but the Problem still exists.
Outside Unity the Eye Tracker works just fine.

So is there a way I can fix this and is the Eye Tracker 4C compatible with the SDK?

Thank you

Hi @janeksteff, sometimes if the gaze points are offset when running the game in the Unity Editor, and the offset increases the closer to the lower-right corner of your screen you are looking, then you probably have a DPI-problem.

On Windows 10 this offset problem is more common since the screen DPI is automatically set to higher values for high-resolution monitors. There are two possible workarounds:

Set the DPI scale for your monitor manually to a value of 125% or lower, or
Build a standalone build and test the eye-tracking related features there

Kindly let us know if this helps to resolve the issue.
