                // Other choices of data streams include EyePositionDataStream and FixationDataStream.
                using (var lightlyFilteredGazeDataStream = eyeXHost.CreateGazePointDataStream(GazePointDataMode.LightlyFiltered)) 
                {
                    // Start the EyeX host.
                    eyeXHost.Start();
                    //label1.Text= ("Gaze point at ({0:0.0}, {1:0.0}) @{2:0}", e.X, e.Y, e.Timestamp);

                // Write the data to the console.
                     lightlyFilteredGazeDataStream.Next += (s,entry) => Console.WriteLine("Gaze point at ({0:0.0}, {1:0.0}) @{2:0}", entry.X, entry.Y, entry.Timestamp);

                    // Let it run until a key is pressed.
                    MessageBox.Show("Gaze data recording, press any key to exit...");
                     
                }
            }
        }
