Hi @wrapcaesar, your syntax looks okay but it’s the combination of trying to output to the console whilst simultaneously using a WPF application that might be tripping you up. Your code never produced any console out on my machine. I think it would be better to create a text box on the WPF form and populate it’s contents with the fixation information or alternatively save the data to an array for later analysis.. have you already tried this? Why do you want the output to a regular windows console seperate from the WPF window?
With reference to catching the point at which gaze is detected on the elements (Rather than the fixation time) then it should be sufficient to simply use the current time method (DateTime.Now) within the if(e.HasGaze) routine.
I would also point out that storing of gaze data for analysis requires the purchase of a special licence to do so. You can read more about this @ https://analyticaluse.tobii.com
