I win7 one, written by the desktop code
Code

    Var eyeXHost = new EyeXHost ();
                Var lightlyFilteredGazeDataStream = eyeXHost.CreateGazePointDataStream (GazePointDataMode.LightlyFiltered);
           
            
                EyeXHost.Start ();
                LightlyFilteredGazeDataStream.Next + = (s, e) =>
                {
               
                    Px = (int) e.X;
                    Py = (int) e.Y;
                    SetCursorPos (px, py);
}}

By getting the screen coordinates of gaze, move the mouse, the accuracy is better.
But when I generated the exe program, into another win10 notebook above, when the test was found to be inaccurate, the right area will not move to the left part of the can not be moved to the overall inaccurate, very distressed, but tobiieyex Management procedures gaze trace of the bubble found that this is indeed very accurate,
My win10 screen resolution is 1920 * 1080, change the text, application and other items size 125%.
My win7 screen resolution is 1600 * 900.

In the end what happened, very distressed. If you can manage the program gaze trace
