    I’m just setting up the Tobii SDK in Unity. I’m able to get the “Adjust Headset screen” but I can’t modify the position of the pupils at all. I followed all steps in the readme but can’t get it to work. “Adjust the HMD until the eyes are placed as centered as possible.” doesn’t work. Is there anything I have to add to get this working? I get following error: “Failed to start calibration thread
    Tobii.Research.Unity.<PerformCalibration>d__20:MoveNext() (at Assets/TobiiPro/VR/Scripts/Utility/VRCalibration.cs:144)
    UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)”




    Found the solution. One driver was not installed correctly.

    OK Thanks for lettings us know @floma, hopefully your post will prove useful to another other users experiencing similar issues. Best Wishes.


    Hi, @florian! Which driver was installed wrong for you? I am having the same issue and don’t really get where is the problem. Thank you!



    @florian, how did you get this working? I am trying to run the calibration from Unity, but haven’t succeeded yet.

    I am using a script called CalibrationHelper, which I received some time ago from Alexey, but that does not seem to work (complication is that I don’t own the Tobii eyetracker myself, I am developing for a customer, so I need to ask them to test it). I can’t find calibration in the Examples nor in the DevTools.

    @grant, is there an example of how to trigger calibration from Unity?

    Hi @joostbos, I sent you a PM with some further instructions and program samples. Hopefully this can help you get up and running in the meantime.
