Being a newbie to the Tobii and to GitHub here is my first attempt. See my sample program at https://github.com/MNDcommunicate/MyGazeForm
This is not exotic, it does however work. I make use of the GazeAware behavior. In the weeks ahead I will have a go at the Activatable Behavior.
Please let me know if you have a play with the sample.
Keep having fun
