    using the EyeX Controller with Unity SDK. I installed everything, calibrated and the examples are working. My problem is with the examples 02 a-b-c in terms of Gaze Selection. I can see the gaze plot but when I’m over the objects nothing happens. I’ve looked up a video of someone using the Unity SDK and there the objects turn blue when selected. In the Inspector there is in fact a Change Color script with the same light blue color.

    Anyone got an idea how this can be? The SDK works but this one feature doesn’t?

    I’m new to Unity. Have been following this https://tobii.github.io/UnitySDK/manual#import-the-sdk-assets and did not modify the examples.

    I also noticed that in example 3, while head presence can be detected, the orientation is not translated to the 3D model as in this video https://developer.tobii.com/pc-gaming/unity-sdk/

    I’ve tried various things from the troubleshooting guide

    and with a 2D and 3D projects … no luck

    Which version of Unity do you use?
    Do you target .NET 3.x or .NET 4.x?
    Could you please check Eye Tracking settings in Unity. Layers should not be empty and MaxDistance should not be zero (try 200 or Infinity)

    Regarding Head pose, Tobii EyeX doesn’t support it. You would need Tobii 4C or IS4/IS5 platform based laptop.


    Got it. Awesome!

    Setting the MaxDistance value to 200 did the trick. Maybe add this to the eye tracking settings part of the troubleshooting guide?

    Thanks Alex 🙂
