**Review of Open Gazer**

   Opengazer has the following workflow:

1. Feature point selection
2. Calibrating the system
3. Tracking

   It is an open source software that estimates the direction of our gaze and it can then be passed into another application. Like for example in the picture below, the box with the blue dot is where the subject has looked, and the box with the red dot is where the system estimated that he will look.
