**Review of !GazeBoard**

   First step of review of !GazeBoard is download, from this location: http://gazerecorder.christiaanboersma.com/gazeboard/. After downloading I installed it on Windows 10. The main interface of !GazeBoard looks like this:

   It has three tabs, Control, Options and Help. The settings that you can change in the options tab are shown in the folowing picture:

   In order to test this software's functionality I did a little experiment with spelling my name. First from the options tab I chose the full type keyboard option, because it works better and it is more precise. Then I tested the calibration option, in which you are told to stay still, not move your head and to look at the red dots. It has a four-dots calibration system. Because calibrating is done also before starting your typing I will provide one photo of the calibrating process:

  After the calibration is done you are redirected to a screen with  your calibration information. Mine is shown in the following picture:

  After this is done you can start typing your words with your eyes.
