Review of TrackEye

First thing to do is download the source code, which is packed as a zip archive on code project website's article. Next I unziped it, and as the instruction for instalation on the website, I copied the two pictures, to the C:/ folder, that are going to be used by the algorithms. There are also suggested settings for a user to set before the starting of the eye-tracking, and they are:
