    Hi, I’m a programmer, so I have decided, for simple curiosity, to test my Tobii integrated system using .NET SDK, I’m able to discover the device, but I’m not able to receive events.

    static void Main(string[] args)
    var trackers = EyeTrackingOperations.FindAllEyeTrackers();
    trackers[0].GazeDataReceived += Program_GazeDataReceived;
    trackers[0].HMDGazeDataReceived += Program_HMDGazeDataReceived;

    while (true)

    What I’m doing wrong?

    Best regards

    You are using the Tobii Pro SDK, that may not work. See your PM for details.

    Hi @gmgunderground, please use the Tobii Interaction Library for use with this tracker.

    We have created a getting started guide with sample code and tutorials which you can read @

    Getting Started

    As you will see, C# bindings are available so you should not have much trouble to get up and running.
    Check it out and let us know how you get on, thanks.


    Hi, with your information, now I have started the 1st test application. I think I was using the wrong SDK. With the interaction library all is working correctly
