    Running sample Interaction_Streams_101 from Github, Windows 10 with VS 2017, Tobii.Interaction.Model.dll is v4.0.30319 and Tobii Eye Tracker app is

    In the image you can see the X coordinates giving values way higher than my screen resolution. I was expecting at least the same precision as the Glaze Trace feature.
    Probably the Glaze Feature uses another library than Tobii.Interaction, but the point is, how to get accurate results?

    This is very frustrating, I’m considering returning the device 🙁

    I believe the coordinates are scaled by DPI factor. So you just need to divide them by it.
