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.

In the example pictures above, 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. After getting the gaze predicted direction with calibration we can use for example another program like Dasher, which is an arcade game where by zooming in an area we write with our looks and the prediction from Open Gazer.
