**Review of !GazePointer** 

 !GazePointer is a Human computer interaction application for controlling the mouse pointer with a person's point of gaze, that is calculated with computer vision algorithms. After downloading the !GazePointer app from http://gazerecorder.christiaanboersma.com/gazepointer-beta/, I installed it in order to test it. It has very simple interface and it is very easy to use.
